Every year, millions of people become infected and die from a variety of diseases, some of which are vaccine-preventable. Although vaccination has led to a dramatic decline in the number of cases of several infectious diseases, some of these diseases remain quite common. In many instances, large populations of the world, particularly in developing countries, suffer from the spread of vaccine-preventable diseases due to ineffective immunization programs, either because of poor implementation, lack of affordable vaccines, or inadequate devices for administering vaccines, or combinations thereof.
Some implementations of immunization programs include administration of vaccines via a reusable syringe. However, in many situations, particularly in developing countries, the administration of vaccines occur outside of a hospital and may be provided by a non-professional, such that injections are given to patients without carefully controlling access to syringes. The use of reusable syringes under those circumstances increases the risk of infection and spread of blood-borne diseases, particularly when syringes, which have been previously used and are no longer sterile, are used to administer subsequent injections. For example, the World Health Organization (WHO) estimates that blood-borne diseases, such as Hepatitis and human immunodeficiency virus (HIV), are being transmitted due to reuse of such syringes, resulting in the death of more than one million people each year.
Previous attempts at providing single-use or disposable injection devices to remedy such problems in the industry have achieved measurable success but have failed to adequately remedy the existing problems. Pre-filled, single-use injection devices manufactured via injection molding or Form-Fill-Seal (FFS) processes, such as the Uniject™ device available from the Becton, Dickinson and Company of Franklin Lakes, N.J., for example, while offering precise manufacturing tolerances in the range of two thousandths of an inch (0.002-in; 50.8 μm) to four thousandths of an inch (0.004-in; 101.6 μm)—for hole diameters in molded parts, require separate sterilization processes (e.g., gamma radiation) that are not compatible with certain fluids, provide production rates limited to approximately nine thousand (9,000) non-sterile units per hour, and can be provided to an end-user for approximately one dollar and forty cents ($1.40) per dose/unit.
Inspection of BFS products such as BFS vials, bottles, cards, etc., that are filled with therapeutic, biologic, medicinal, and/or other injectable fluids, presents challenges that are not addressed by previous inspection systems.
Embodiments of the disclosed subject matter provide systems and methods for inspecting a pre-filled blow-fill-seal (BFS) product. For example, in embodiments, the BFS product can include a plurality of BFS vials formed together during a BFS manufacturing process. Each BFS vial can have a neck with a coupling portion that is used to secure and seal an administration assembly to the BFS vial for subsequent use. In some embodiments, proper operation of the BFS assembly (e.g., avoiding leakage between the neck and the administration assembly) may be influenced by the configuration of the neck and/or the coupling portion. The neck can thus be inspected after manufacturing, for example, to determine proper shape and size of the coupling portion.
While conventional methods for inspection (e.g., machine vision) may have issues inspecting such necks, embodiments of the disclosed subject matter can perform inspection using a unique illumination and detection configuration, which allows imaging of the BFS vial neck despite being formed of a translucent plastic. Other features of the BFS product and/or BFS vials can also be inspected, such as, but not limited to, a tab (e.g., including printed or embossed information), a reservoir (e.g., particular within a liquid product sealed within the reservoir), fluid seal of neck (e.g., shape of fluid seal, or defect therein), or a product body (e.g., shape of shoulder, particulate within body).
In some embodiments, all of the BFS vials of the BFS product are inspected to determine compliance of the BFS product. Alternatively, in some embodiments, only one or some of the BFS vials (e.g., only the laterally outer vials) are inspected to determine compliance of the BFS product (e.g., the compliance determination may be imputed to all of the BFS vials of the BFS product even if not specifically inspected). Alternatively or additionally, in some embodiments, only one or some of the BFS products are inspected for compliance, for example, a periodic or random inspection for quality control.
In one or more embodiments, an inspection system for a pre-filled BFS product can comprise one or more first inspection stations and a controller operatively coupled thereto. The BFS product can have first and second ends spaced from each other along a longitudinal direction. The BFS product can comprise one or more necks at the first end that extend along the longitudinal direction. Each neck can comprise a coupling portion that protrudes laterally outward with respect to adjacent portions of the neck. Each first inspection station can comprise an illumination assembly and a detection assembly. The illumination assembly can comprise one or more light sources and can be constructed such that interrogating light from the light sources is directed at a perimeter of a coupling portion of a neck disposed at a target position. The detection assembly can comprise one or more imaging devices. The detection assembly can have an input optical axis extending from the target position along the longitudinal direction and can be arranged to detect light emitted from the neck disposed at the target position. The controller can be configured to determine compliance of the BFS product with respect to one or more predetermined criteria based at least in part on the light detected by the one or more imaging devices.
Any of the various innovations of this disclosure can be used in combination or separately. This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter. The foregoing and other objects, features, and advantages of the disclosed technology will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures.
Where applicable, some elements may be simplified or otherwise not illustrated in order to assist in the illustration and description of underlying features. For example, in some figures, some components have been illustrated using a partial or cutaway view in order to illustrate internal interaction of components. Throughout the figures, like reference numerals denote like elements. An understanding of embodiments described herein and many of the attendant advantages thereof may be readily obtained by reference to the following detailed description when considered with the accompanying drawings, wherein:
Described herein are systems, assemblies, and methods for inspecting pre-filled medical delivery assemblies. In some embodiments, the medical delivery assemblies include at least one blow-fill-seal (BFS) vial (also referred to herein as a component, container, or bottle) that has one or more reservoirs (also referred to herein as chambers) prefilled with one or more liquid agents using a BFS manufacturing technique. The reservoirs filled with the liquid agents can be sealed from the environment until dispensing thereof is desired (e.g., a time for administration to the patient). The BFS vial may be constructed, filled, and sealed, according to some embodiments, in a sterile manufacturing environment. In some embodiments, multiple BFS vials can be simultaneously formed together as a single BFS product (also referred to herein as a module or card), which can then be separated into subsets or individual BFS vials for subsequent storage and/or use. BFS vials may, for example, offer a less expensive alternative to typical vials or bottles created via other manufacturing techniques.
In some embodiments, BFS modules (e.g., due to the nature of the BFS manufacturing process) may not require separate sterilization (and thereby may be compatible with a wider array of liquid agents), may provide enhanced production rates of sterile/aseptic units per hour, and/or may be provided to an end-user for significantly lower per dose/unit costs. In some embodiments, these advantages may come with an attendant drawbacks of reduced manufacturing tolerances and other disadvantages of utilizing a “soft” plastic (e.g., having a Shore/Durometer “D” hardness of between 60 and 70). BFS processes may, for example, offer less precise manufacturing tolerances in the range of five hundredths of an inch (0.05-in; 1.27 mm) to fifteen hundredths of an inch (0.15-in; 3.81 mm)—for linear dimensions, e.g., in accordance with the standard ISO 2768-1 “General tolerances for linear and angular dimensions without individual tolerance indications” published by the International Organization for Standardization (ISO) of Geneva, Switzerland (Nov. 15, 1989), which is incorporated herein by reference.
Referring initially to
In some embodiments, the BFS vial 110 may also comprise and/or define a tab 126 upon and/or in which various identifying information (e.g., descriptive of the fluid agent contained within the vial) is provided. For example, the identifying information may comprise various printed, engraved (e.g., laser engraved), embossed, adhered, radio-frequency identification (RFID), quick response (QR) code, barcode, and/or other informational objects (human and/or computer-readable) that are indicative of one or more characteristics of the vial, a product card of which the vial was a part, the manufacturing process/device/location, and/or the fluid agent(s). In some embodiments, the identifying information may comprise first information disposed on a first side or face of the tabs 126 (e.g., the front side as shown in
In some embodiments, the pre-filled medical delivery assembly 100 may comprise an administration module or component 130 that is, e.g., maintained as a closed and/or sterile component via a seal 132 (e.g., a foil, wax, paper, and/or other thin, pierceable, tear-able, and/or removable object or layer coupled to the administration component 130) that seals an interior volume of hub 134 disposed at a first end thereof. According to some embodiments, the hub 134 may comprise and/or define (e.g., on or in an interior surface thereof) a shaped seat 136 that is configured to accept the coupling portion 116 of the BFS vial 110 (e.g., in the case that the neck 112 of the BFS vial 110 is inserted into the hub 134). In some embodiments, the administration component 130 may comprise and/or be coupled to an administration member 140 (e.g., a cannula or needle). In some embodiments, the administration member 140 can be inserted into and/or extend through the hub 134, for example, such that it comprises a first or administration end extending longitudinally distal from the BFS vial 110 and a second end disposed within the hub 134 and/or extending into the BFS vial (e.g., in the case that the vial 110 is coupled to the hub 134). In some embodiments, the administration end and/or a distal portion of the administration member 140 may be housed, shrouded, and/or covered by a cap 150, which may be removably coupled to the hub 134 (e.g., via friction fit with an external portion of the hub).
In some embodiments, the administration member 140 may comprise a needle for at least one of subcutaneous, intramuscular, intradermal, and intravenous injection of the fluid agent into the patient. For example, the needle can have a length of 0.5 mm to 4 mm, inclusive, or in a range of 4 mm to 15 mm, inclusive, or in a range of 15 mm to 30 mm, inclusive, depending on the desired manner of injection. For ease of explanation and description, the figures and the description herein generally refer to the administration member as a needle. However, it should be noted that, in other embodiments, the administration member 140 may include a nozzle (not shown) configured to control administration of the fluid agent to the patient. The nozzle may include a spray nozzle, for example, configured to facilitate dispersion of the fluid agent into a spray. Accordingly, a hub 134 fitted with a spray nozzle may be particularly useful in the administration of a fluid agent into the nasal passage, for example, or other parts of the body that benefit from a spray application (e.g., ear canal, other orifices). In other embodiments, the nozzle may be configured to facilitate formation of droplets of the fluid agent. Thus, a hub 134 including a droplet nozzle may be useful in the administration of a fluid agent by way of droplets, such as administration to the eyes, topical administration, and the like.
In the illustrated example of
In some embodiments, the one or more reservoirs 120, 122 may be filled (fully or partially) with a fluid or other agent (not separately shown) to be delivered, e.g., to a patient (not shown). According to some embodiments, the fluid may be injected into the BFS vial 110 during manufacture via a BFS process (e.g., in a sterile environment) and sealed within the BFS vial 110 via the fluid seal 114. In some embodiments, the reservoirs 120, 122 may be joined by a constriction 124 (also referred to herein as a passage, juncture, junction, depression, indentation, relief, geometric transition, grip point, valve, restriction, or narrowed portion), as shown in
As generally understood, the fluid or drug agent sealed within the BFS vial 110 (or BFS vial 150) may include any type of agent to be injected into a patient (e.g., mammal, either human or non-human, or any other animal) and capable of producing an effect (alone, or in combination with an active ingredient). Accordingly, the agent may include, but is not limited to, a vaccine, a drug, a therapeutic agent, a medicament, a diluent, and/or the like. According to some embodiments, either or both of the fluid agent and the active ingredient (i.e., the drug agent and/or components thereof) may be tracked, monitored, checked for compatibility with each other, etc., such as by utilization of electronic data storage devices (not shown) coupled to the various modules or components of the pre-filled multi-liquid medical delivery assembly, such as the BFS vial 110 and/or administration component 130.
In some embodiments, the BFS vial 110 and administration assembly 130 may be coupled, e.g., in the field and/or in situ, to provide an active pre-filled (e.g., injectable) medical delivery assembly 100. As shown in
As depicted in
Alternatively, in some embodiments, the neck of the BFS vial can be provided with a coupling portion (or mounting flange) constructed for interfacing with threads in the hub to secure the BFS vial to the administration assembly. For example, in place of or in addition to coupling portion 116 in neck 112 of BFS vial 110 (or coupling portion 156 in neck 152 of BFS vial 150), the coupling portion of the BFS vial can define and/or comprise an external thread element (e.g., one or more Luer-style thread protrusions). In some embodiments, the external thread element can be constructed as an angled exterior flange designed to fit within a cooperative and/or mirrored angled interior groove or track within the hub.
In some embodiments, the administration component 130 (and/or the cap 150) may be composed of a medical grade material. In some embodiments, the administration component 130 (and/or the cap 150) may be composed of a thermoplastic polymer or other relatively hard plastic (e.g., greater than 80 on the Rockwell “M” scale; e.g., Rockwell M 85; and/or greater than 110 on the Rockwell “M” scale; e.g., Rockwell R 115), such as, but not limited to, polypropylene, polybenzimidazole, acrylonitrile butadiene styrene (ABS), polystyrene, polyvinyl chloride, polycarbonate, or the like. In some embodiments, the pre-filled medical delivery assembly 100 may be advantageously manufactured (in mass quantities) in separate parts or portions, namely, at least the “soft” plastic BFS vial 110 portion (e.g., a “first” piece) and the “hard” plastic administration component 130 (e.g., the “second” piece), with such different plastic parts/portions being selectively coupled to administer a medication to a patient.
In some embodiments, fewer or more components 110-166 and/or various configurations of the depicted components 110-166 may be included in the pre-filled medical delivery assembly 100 without deviating from the scope of embodiments described herein. In some embodiments, the components 110-166 may be similar in configuration and/or functionality to similarly named and/or numbered components as described herein. According to some embodiments, the pre-filled medical delivery assembly 100 may comprise the coupling portion 116 but not the collapsible reservoir 120. In some embodiments, the pre-filled medical delivery assembly 100 may comprise the coupling portion 116 but not the dispensing reservoir 122.
Each BFS vial can have a neck with a coupling portion that is used to secure and seal an administration assembly to the BFS vial for subsequent use. In some embodiments, proper operation of the BFS assembly (e.g., avoiding leakage between the neck and the administration assembly) may be influenced by the configuration of the neck and/or the coupling portion. The neck can thus be inspected after manufacturing, for example, to determine proper shape and size of the coupling portion, among other features. While conventional methods for inspection (e.g., machine vision) may have issues inspecting such necks, embodiments of the disclosed subject matter can perform inspection using a unique illumination and detection configuration, which allows imaging of the BFS vial neck despite being formed of a translucent plastic. Other features of the BFS product and/or BFS vials can also be inspected, such as, but not limited to, a tab (e.g., including printed or embossed information), a reservoir (e.g., particular within a liquid product sealed within the reservoir), fluid seal of neck (e.g., shape of fluid seal, or defect therein), or a product body (e.g., shape of shoulder, particulate within body).
In some embodiments, the inspection system 326 can comprise one or more inspection stations 328, for example, at least one station for inspecting a neck of BFS vial 110. A controller 330 can be operatively coupled to the inspection station 328 for controlling operation thereof. Alternatively or additionally, in some embodiments, the controller 330 is coupled to the inspection station 328 to receive one or more signals from the inspection station 328 indicative of a result of the inspection and/or one or more data signals (e.g., providing information that can be used by the controller 330 to form an image and to perform a comparison with predetermined criteria). In some embodiments, the controller 330 can be configured to control transport of the BFS vial 110 through the inspection system 326 based at least in part on a result of the inspection. For example, in some embodiments, if the inspection by station 328 indicates that the BFS vial 110 does not comply with one or more predetermined criteria (e.g., as determined by the inspection station 328 and/or controller 330), the controller 330 can redirect the BFS vial 110 to move along a rejection path 334 rather than via output path 332.
In some embodiments, inspection of the neck of the BFS vial 110, in particular a coupling portion thereof, may be complicated due to the translucent nature of the plastic comprising the BFS vial and the relatively small sizes of the BFS vial features being inspected (e.g., a neck diameter of 6.5-6.65 mm and/or a protrusion amount of the coupling portion from the neck of 0.8-1.6 mm), especially if axial lighting (e.g., directed along longitudinal direction, z) and axial detection (e.g., with an input optical axis extending along longitudinal direction, z) are both used to image the BFS vial 110. Accordingly, in some embodiments, angled lighting can be employed together with axial detection, which may allow for the capture of images that have a resolution conducive to image analysis processing.
For example,
In some embodiments, the illumination assembly can comprise one or more light sources (or lighting devices), for example, four light sources 342a-342d, for example, arranged at equal intervals (e.g., to form angle 358 between adjacent light paths 346a-346d of)—90° around the perimeter of the neck 112 of the BFS vial, as shown in
In some embodiments, each light source 342a-342d can have one or more optical components 344a-344d that direct the interrogating light along the appropriate path 346a-346d toward the neck 112. For example, the one or more optical components 344a-344d can comprise a light tube (or pipe), an optical fiber, a lens, a filter, a reflector, or any combination thereof. In some embodiments, the interrogating light can have one or more wavelengths in a range from 10 nm to 1 mm inclusive, for example, in a range from 400-700 nm (e.g. visible light). In some embodiments, each light source 342a-342d can comprise a laser source, a laser diode, or a light emitting diode (LED).
In the illustrated example, the interrogating light from light sources 342a-342d can be directed to provide lateral plane illumination (e.g., substantially parallel to x-y plane) and/or can be directed substantially along a radial direction of the coupling portion 116. For example, paths 346a-346d of the interrogating light can be directed along a plane substantially perpendicular to the longitudinal direction and/or the input optical axis 348 of the detection assembly. In some embodiments, the paths 346a-346d of the interrogating light can thus form an angle 356 with the input optical axis 348 of −90°. Alternatively or additionally, in some embodiments, the light paths 346a-346d can be directed at an angle away from the longitudinal axis (e.g., the axial direction and/or vertical direction), such that light from the light sources cannot directly enter an input aperture of the detection optical assembly and/or such that only light scattered or reflected by the neck 112 enters input aperture and is detected by imaging device 352. For example, in some embodiments, the paths 346a-346d can be directed at an angle with respect to the lateral plane, but such that a major component of the light along the lateral direction exceeds the components of the light along the longitudinal direction. For example, in some embodiments, the paths 346a-346d of the interrogating light can form an angle 356 with the input optical axis 348 that is less than or equal to 135°.
In the illustrated example of
The method 400 can proceed to process block 404, where interrogating light can be directed onto or surrounding the neck of the BFS vial at the target position. For example, the interrogating light can be directed at the coupling portion of the neck, or at other portions of the neck proximal to the coupling portion. In some embodiments, the interrogating light can be directed along lateral directions (e.g., substantially along a radial direction of the neck) so as to be incident on or around the circumference or perimeter of the coupling portion of the neck, for example, as described herein. In some embodiments, the interrogating light is provided by an illumination assembly with one or more lights sources.
The method 400 can proceed to process block 406, where the light emanating or emitted from the BFS vial is detected. For example, in some embodiments, a detection optical assembly, which has an input optical axis extending from a target position along the longitudinal direction, can be used to detect the light from the BFS vial. The detection optical assembly can thus be arranged to collect and detect light that has been emitted axially from the BFS vial in response to the illumination of process block 404. In some embodiments, an axial image of at least the coupling portion (and optionally other portions of the neck, such as the end seal) is formed based on the detected light from the BFS vial.
The method 400 can proceed to process block 408, where it is determined if at least the coupling portion (and optionally other portions of the BFS vial) is within acceptable parameters (e.g., compliant with one or more predetermined criteria). For example, in some embodiments, various shapes, orientations, sizes, and/or other features of the coupling portion and/or neck of the BFS vial in the obtained image may be compared to stored images, templates, geometries, dimensions, etc. to determine whether the inspected BFS vial falls within acceptable parameters. Based on the determination of process block 408, the method can perform an action indicative of the determination, for example, by providing a visual or audible alarm, by automatically routing non-compliant or defective BFS vials, by automatically routing compliant or acceptable BFS vials, and/or by providing feedback to a BFS molding machine to automatically adjust parameters thereof to obtain more compliant BFS vials. In some embodiments, the determination of process block 408 can take into account multiple inspections of different BFS vials. For example, an inspection system can evaluate multiple BFS vials or products produced by a BFS molding machine and can identify failure trends that may indicate a problem with molding or other aspects of the BFS product fabrication. In some embodiments, feedback based on the identified trends can be sent to one or more upstream fabrication systems, for example, to generate an alarm or halt production to address the problem.
Although some of blocks 402-408 of method 400 have been described as being performed once, in some embodiments, multiple repetitions of a particular process block may be employed before proceeding to the next decision block or process block. In addition, although blocks 408-408 of method 400 have been separately illustrated and described, in some embodiments, process blocks may be combined and performed together (simultaneously or sequentially). For example, the illumination of process block 404 may generally occur at the same time as the imaging in process block 406. Moreover, although
Referring to
In some embodiments, each BFS vial 110a-110e may comprise and/or be interconnected with an adjacent BFS vial 110a-110e via plastic web 121, which may comprise, for example, unformed portions of plastic substrate utilized in the BFS manufacturing process. In some embodiments, after separation of the BFS vial from the BFS product card 102, the body flange 118 can be formed by severed or cut portions of the plastic web 121. According to some embodiments, the plastic web may be trimmed adjacent to each respective neck 112 to define a shoulder portion 119. In some embodiments, each neck 112 (or each internal void defined thereby; not separately labeled) may be in fluid communication with a respective fluid reservoir 122. According to some embodiments, the fluid reservoirs 122 and fluid seals 114 at a terminal end of each neck 112 may act to maintain any fluids (not explicitly shown) in the respective fluid reservoirs 122 and/or necks 112. In some embodiments, the fluid reservoirs 122 may be filled (fully or partially) with a fluid, liquid, or other agent (not separately shown in
According to some embodiments, each fluid reservoir 122 may be in fluid communication with a respective compressible reservoir 120. The compressible reservoirs 120 may, for example, retain a portion (some or all) of the fluid agent and/or may comprise a second fluid such as air. In some embodiments, a first junction “A” may be formed and/or defined between each fluid reservoir 122 and each respective compressible reservoir 120. According to some embodiments, a second junction “B” (e.g., a depression, indent, relief, geometric transition, grip point, etc.) may be formed and/or defined between each compressible reservoir 120 and each respective tab 126.
In some embodiments, the BFS product 202 can be subject to inspection for compliance, for example, with respect to one or more predetermined criteria. For example, the coupling portion 116 of one, some, or all of the BFS vials 110a-110e of the BFS product 202 can be checked for conformance to acceptable shapes, sizes, and/or ranges thereof. For example, the predetermined criteria can include an acceptable value or range of values for lateral dimension of the coupling portion 116, a lateral dimension of one of the adjacent portions of the neck 112, amount of lateral protrusion of the coupling portion 116 with respect to one of the adjacent portions of the neck (e.g., proximal to seal 114 and/or proximal to shoulder 119), a difference between lateral dimension of the coupling portion 116 and lateral dimension of one of the adjacent portions of the neck 112, or any combination of the foregoing.
In some embodiments, other portions of the BFS produce 202 besides the coupling portion can be inspected, for example, before or after inspection of the coupling portion 116. For example, the inspected features of the BFS product 202 can include, but are not limited to, (i) the shape and/or dimensions of the fluid reservoirs 122, (ii) the shape and/or dimensions of the shoulders 119, (iii) the shape and/or dimensions of the compressible reservoirs 120, (iv) whether any particles 123 are embedded in the plastic walls of the BFS product 202, (v) the opacity of the walls of the BFS product 202, (vi) whether any portions of the BFS product 202 are deformed, (vii) whether the edges of the BFS product 202 are properly punched/trimmed, (viii) whether the BFS product 202 comprises any excess plastic, and/or (ix) whether liquid is present in the BFS product 202 (e.g., in the fluid reservoirs 122 and/or necks 112). According to some embodiments, in the case that any data (or any amount of and/or type of data exceeding a stored threshold) does not fall within acceptable thresholds, the BFS product 202 may be rejected and/or flagged with a failure indication and/or status.
In some embodiments, only a portion of the BFS product 202 may be inspected (e.g., laterally-outermost BFS vials, such as leading vial 110a and/or trailing vial 110e). In such embodiments, the compliance results can be imputed to all of the vials 110a-110e in the BFS product 202, or the BFS product 202 can be flagged for more intensive inspection (e.g., of each vial). Alternatively or additionally, in some embodiments, each vial 110a-110e in the BFS product 202 can be inspected.
In some embodiments, the conveying of process block 602 can be via or include an infeed conveyor or drive mechanism of the BFS inspection system. According to some embodiments, incoming BFS product may be directed to and/or accepted via a staged infeed. The speed of the infeed may be set and/or varied to ensure an adequate separation distance between BFS products traveling through the BFS product inspection system, for example. According to some embodiments, the BFS product inspection system may be in communication with upstream devices such that start, stop, alarm, and/or speed settings or other information is exchanged between interconnected devices to maintain coordination of the manufacturing, assembly, inspection, packaging, and/or distribution line.
The method 600 can proceed to decision block 604, where it is determined if the BFS product should bypass inspection. If bypass is desired, the method 600 can proceed to process block 606, where the BFS product can be diverted prior to any inspection. For example, BFS products may be selectively ejected by activation of a bypass ejection mechanism. In some embodiments, faulty BFS products and/or products that need to be excluded to maintain separation distances and/or other operations of the BFS product inspection system may, for example, be directed into a bypass line and/or bin at process block 604. For diverted BFS product, the inspection of method 600 may end, but the inspection of method 600 may otherwise continue for subsequent BFS products.
If no bypass is desired, the method 600 can proceed to process block 608, where the BFS product can be conveyed using a first configuration for drive engagement. For example, a drive mechanism can be used that grips or otherwise supports the BFS product while exposing at least the tab for inspection. For example, the drive mechanism can contact or engage with a constriction or junction between axially-adjacent reservoirs of one or more vials of the BFS product. Alternatively or additionally, the drive mechanism can contact or engage with opposing surfaces of reservoirs of one or more vials of the BFS product.
The method 600 can proceed to process block 610, where a front of a tab of the BFS module is inspected, for example, by conveying the BFS product through a first tab inspection station. For example, various markings, indicia, and/or other information descriptive of the BFS product and/or the fluid therein and that are disposed in or on a front tab (or other frontal element) of the BFS product may, for example, be sensed, read, captured, interpreted, decoded, and/or analyzed to determine if the information falls within acceptable parameters. According to some embodiments, the frontal tab inspection may comprise reading laser engraving markings on the front of the tab of the BFS product.
The method 600 can proceed to process block 612, where a rear of a tab of the BFS module is inspected, for example, by conveying the BFS module through a second tab inspection station. For example, various markings, indicia, and/or other information descriptive of the BFS product and/or the fluid therein and that are disposed in or on a rear tab (or other rear element) of the BFS product may, for example, be sensed, read, captured, interpreted, decoded, and/or analyzed to determine if the information falls within acceptable parameters. According to some embodiments, the rear tab inspection may comprise reading embossed markings on the rear of the tab of the BFS product.
The method 600 can proceed to decision block 614, where it is determined if the drive mechanism configuration should be changed, for example, to allow exposure of other portions of the BFS product that may otherwise by covered or obscured by the current drive mechanism configuration. If changing the drive mechanism configuration is desired, the method 600 can proceed to process block 616, where the drive mechanism configuration is changed. In some embodiments, the BFS product can be transferred from a current drive mechanism to a new drive mechanism via an overlapping handoff region. For example, the new drive mechanism can contact or engage with a constriction or narrowed region between the tab portion and a reservoir of one or more vials of the BFS product.
After process block 616, or after decision block 614 if no drive configuration change is desired, the method 600 can proceed to process block 618, where a neck of the BFS product can be inspected, for example, by conveying the BFS product through a neck inspection station. In some embodiments, an axially-oriented imaging and/or other sensor device (e.g., having an input optical axis substantially parallel to a longitudinal direction of the BFS product) may be utilized to capture information descriptive of the neck, seal, coupling portion, shoulder, and/or other features of the BFS vial. In some embodiments, and as described herein, such an inspection may be performed advantageously by utilizing angled lighting sources that direct light at or around the circumference of the neck and/or coupling portion—e.g., as opposed to from below or above (e.g., axially) the BFS product. According to some embodiments, various shapes, orientations, sizes, and/or other features of the neck area of the BFS product may be compared to stored images, templates, geometries, dimensions, etc. to determine whether the inspected BFS product falls within acceptable parameters.
The method 600 can proceed to decision block 620, where it is determined if the drive mechanism configuration should be changed, for example, to allow exposure of other portions of the BFS product that may otherwise by covered or obscured by the current drive mechanism configuration. If changing the drive mechanism configuration is desired, the method 600 can proceed to process block 622, where the drive mechanism configuration is changed. In some embodiments, the BFS product can be transferred from a current drive mechanism to a new drive mechanism via an overlapping handoff region. For example, the new drive mechanism can contact or engage with a constriction or narrowed region between the tab portion and a reservoir of one or more vials of the BFS product.
After process block 622, or after decision block 620 if no drive configuration change is desired, the method 600 can proceed to process block 624, where a front of a body of the BFS module is inspected, for example, by conveying the BFS product through a front body inspection process. For example, a frontal oriented imaging and/or other sensor device may be utilized to capture information descriptive of features of the front of the body of the BFS vial. In some embodiments, various shapes, orientations, sizes, and/or other features of the body of the BFS product may be compared to stored images, templates, geometries, dimensions, etc. to determine whether the inspected BFS product falls within acceptable parameters.
The method 600 can proceed to process block 626, where a rear of a body of the BFS module is inspected, for example, by conveying the BFS product through a rear body inspection process. For example, a rear oriented imaging and/or other sensor device may be utilized to capture information descriptive of features of the rear of the body of the BFS vial, for example. In some embodiments, various shapes, orientations, sizes, and/or other features of the body of the BFS product may be compared to stored images, templates, geometries, dimensions, etc. to determine whether the inspected BFS product falls within acceptable parameters. In some embodiments, the body of the BFS product (front and/or rear) may be inspected to identify and/or analyze the presence, amount, location, and/or other characteristics (e.g., color, viscosity) of the fluid agent within the BFS product.
The method 600 can proceed to decision block 628, where it is determined if the BFS product failed one or more aspects of inspection, for example, by being outside the bounds or otherwise non-compliant with one or more predetermined criteria. If the BFS product failed, the method 600 can proceed to process block 630, where the BFS product is redirected or diverted to follow a rejected product path. In some embodiments, the BFS product may be directed through a first reject gate, a second reject gate, or a third reject gate. Each reject gate may, for example, correspond to a different type of identified defect, problem, and/or failure reason or status. In some embodiments, each reject gate may be selectively activated by the BFS product inspection system to direct failed BFS products into appropriate reject areas, lines, bins, etc.
If the BFS product did not fail any inspection (or if the BFS product passes all, or more than a threshold amount, of the inspection processes), the method 600 can proceed to process block 632, where the BFS product is redirected or otherwise allowed to proceed along an output path, for example, via an outfeed conveyor. In some embodiments, the outfeed conveyor may, for example, re-orient the BFS products for packaging and/or shipping such as by causing the BFS products to lay flat and/or to be transported up an inclined slope to be deposited into one or more storage or shipping containers.
Although some of blocks 602-632 of method 600 have been described as being performed once, in some embodiments, multiple repetitions of a particular process block may be employed before proceeding to the next decision block or process block. In addition, although blocks 602-632 of method 600 have been separately illustrated and described, in some embodiments, process blocks may be combined and performed together (simultaneously or sequentially). For example, inspection of the neck of one BFS product in process block 618 may occur at the same time as inspection of the tab of another BFS product in process block 610 or 612. Moreover, although
An exemplary BFS product inspection system 200 will now be described in a manner that generally follows the path of any one or more BFS products 202 through the BFS product inspection system 200, in accordance with at least one embodiment of the BFS product inspection system 200. Variations in the path, order of processes and/or associated positioning of related inspection equipment and/or sensors are also possible according to one or more contemplated embodiments. In some embodiments, the BFS product inspection system 200 may be utilized to inspect various BFS products 202 such as the individual pre-filled BFS cards depicted in the figures. While these specific BFS products 202 are depicted for non-limiting exemplary purposes, other types, quantities, and/or configurations of BFS products 202 may be utilized in the BFS product inspection system 200 in accordance with some embodiments.
Referring to
In some embodiments, the control portion 230 may further comprise, for example, one or more displays 234a-b such as first and second Human-Machine Interface (HMI) displays. According to some embodiments, the displays 234a-b may output various visual information (e.g., data, images, graphs, warnings, etc.) regarding the operation of the BFS inspection machine 220 and/or regarding results of analyzing one or more of the BFS products 202. According to some embodiments, the control portion 230 may comprise an indicator device 236 (e.g., strobe light, single or multi-color indicator light, visual or audible alarm, speaker, any combination thereof, etc.). The indicator device 236 may, for example, be prominently positioned for optimal visibility by an operator (not shown).
In some embodiments, the housing 222 of the BFS inspection machine 220 may be coupled to and/or may retain a base portion 240. The base portion 240 may, for example, be disposed upon and/or supported by the feet 224 and/or may couple to and/or comprise or retain the supports 226. According to some embodiments, the base portion 240 may comprise and/or define an electrical access panel 240-1 (e.g., that controls access to the internal components of the BFS inspection machine 220 such as wires, cables, processing devices, controllers, circuit boards, breakers, relays, switches, etc. —none of which are shown), a bypass bin 242, and/or one or more reject bins 244a-c. As depicted (see, e.g.,
According to some embodiments, the BFS inspection machine 220 may be coupled to and/or may retain or define an operations portion 250. The operations portion 250 may be disposed between the control portion 230 and the base portion 240, for example, and may be oriented and/or configured to align an infeed processing section 260 with upstream manufacturing elements (not shown—e.g., upstream devices and/or a manual feed device). For example, the BFS product 202 can initially be received at the infeed processing section 260, which can be configured to receive fabricated BFS products 202 directly from a BFS molding machine (e.g., conveyed from a demolding stage of BFS shuttling machine or a BFS rotary machine) or indirectly from a BFS molding machine (e.g., via a post-processing station, such as label creation station (e.g., laser-etching of and/or adhesive label fixing on tabs 126), punching station (e.g., to trim excess plastic), and/or card separation station (e.g., where a larger BFS product is separated into smaller constituent cards of multiple vials)).
The BFS product 202 can be conveyed from the infeed processing section 260 to inspection processing section 270 within the operations portions 250 for inspection and then to a routing (e.g., outfeed) section 280. In some embodiments, the inspection processing section 270 comprises and/or is defined by one or more stations (also referred to herein as sub-sections) arranged for sequential or parallel inspection of one or more physical attributes of the BFS product 202. For example, inspection processing section 270 can have a tab inspection station 270A, a neck inspection station 270B, and/or a body inspection station 270C.
Referring to
In some embodiments, the infeed processing section 260 may comprise an infeed belt retraction mechanism 264 that is operable to selectively redirect the infeed drive belt 262 to divert incoming BFS product 202. The infeed belt retraction mechanism 264 may, for example, pivot the plane of the infeed drive belt 262 such that one or more incoming BFS products 202 are directed through a bypass chute 266 and into the bypass bin 242. In some embodiments, the infeed belt retraction mechanism 264 may be utilized to prevent BFS products 202 from progressing into the inspection processing section 270 of the operations portion 250 of the BFS inspection machine 220 such as in the case of inspection processing failures and/or slow the rate of incoming BFS products 202. The BFS products 202 may be spaced at a desired spacing, for example, such as by controlling the speed of the infeed drive belt 262, operating the infeed belt retraction mechanism 264, and/or controlling the speed of the inspection processing section 270.
In some embodiments, any BFS products 202 not directed through the bypass chute 266 may be passed from the guide rails 260-2a, 260-2b and by the infeed drive belt 262 to a cooperating (first) planar drive 268, as shown in
In some embodiments, and as shown in
As shown in
According to some embodiments, any or all indicia from either or both sides of the tabs 126 may be sensed and/or analyzed by the BFS inspection machine 220 as part of the tab inspection sub-section 270A of the inspection processing section 270. The indicia may be compared to store data to ensure that the BFS product 202 identifiers (e.g., batch number, manufacturing information, fluid agent identifier and/or amount/dosage) match stored values. According to some embodiments, the operator may utilize the control portion 230 to input a desired indicia value to which the data sensed from the tabs 126 can be compared and/or matched. In some embodiments, in the case that any data (or any amount of and/or type of data exceeding a stored threshold) does not match, the BFS product 202 may be rejected and/or flagged with a failure indication and/or status.
As shown in
As noted above, due to the nature of the translucent plastic forming the BFS product 202, for example, angled lighting may permit the neck imaging device 272B to capture images that have a resolution conducive to image analysis processing, for example, in order to characterize the compliance of the coupling portion 116 with predetermined criteria. In contrast, axial lighting may significantly reduce the image quality such that the resolution is not conducive to image analysis processing. Thus, in some embodiments, the lighting devices 276B-1, 276B-2, 276B-3, 276B-4 may comprise one or more light tubes and/or fiber optic pathways that are oriented to direct light to specific portions of the necks 112 (e.g., coupling portion 116) of the BFS product 202 and/or at specific angles with respect to the orientation of the neck imaging device 272B. As depicted in
In some embodiments, the imagery/data captured by the neck imaging device 272B may be analyzed to identify and/or quantify various characteristics of the necks 112 of the BFS product 202. The neck inspection sub-section 270B may analyze, for example, (i) the shape and/or dimensions of the coupling portions 116, (ii) the shape and/or dimensions of other portions of the necks 112, and/or (iii) the shape and/or dimensions of the seals 114. According to some embodiments, in the case that any data (or any amount of and/or type of data exceeding a stored threshold) does not fall within acceptable thresholds, the BFS product 202 may be rejected and/or flagged with a failure indication and/or status.
As shown in
As discussed above, the first planar drive 268 may engage and/or support the BFS product 202 at or via the first junction “A”, which may expose the tabs 126 and the necks 112, seals 114, and coupling portions 116 for inspection. However, this support configuration may obscure or cover other portions of the BFS product 202, such as all or part of reservoirs 120, 122. Accordingly, in some embodiments, the second planar drive 278 can be used to expose the reservoirs for subsequent inspection, for example, by engaging and/or supporting the BFS product 202 at or via the second junction “B.” In some embodiments, and as shown in
In some embodiments, a planar drive motor 278-3 may be mounted to engage with (e.g., impart rotation to) two (2) planar drive gears 278-4a, 278-4b. According to some embodiments, a dual-drive bracket 278-5 may be coupled to retain and/or house two (2) planar drive shafts 278-6a, 278-6b, one for each cooperative second frontal and second rear planar drive platforms 278-1a, 278-1b. In some embodiments, the planar drive shafts 278-6a, 278-6b and/or the planar drive gears 278-4a, 278-4b may be coupled to drive either or both of the second drive bands 278-2a, 278-2b of the second planar drive 278 and the first drive bands 268-2a, 268-2b of the first planar drive 268. In such a manner, for example, the drive bands 268-2a, 268-2b, 278-2a, 278-2b may all be maintained at the same velocity, e.g., to ensure steady and smooth movement of the BFS product 202 through the inspection processing section 270.
As shown in
In some embodiments, the imagery/data captured by the body imaging devices 2720-1, 272C-2 may be analyzed to identify and/or quantify various characteristics of the BFS product 202. The body inspection station 270C may analyze, for example, (i) the shape and/or dimensions of the fluid reservoirs 122, (ii) the shape and/or dimensions of the shoulders 119, (iii) the shape and/or dimensions of the compressible reservoirs 120, (iv) whether any particles are embedded in the plastic walls of the BFS product 202, (v) the opacity of the walls of the BFS product 202, (vi) whether any portions of the BFS product 202 are deformed, (vii) whether the edges of the BFS product 202 are properly punched/trimmed, (viii) whether the BFS product 202 comprises any excess plastic, and/or (ix) whether liquid is present in the BFS product 202 (e.g., in the fluid reservoir 122 and/or neck 112). According to some embodiments, in the case that any data (or any amount of and/or type of data exceeding a stored threshold) does not fall within acceptable thresholds, the BFS product 202 may be rejected and/or flagged with a failure indication and/or status.
In some embodiments, the BFS product 202 may be driven by the second planar drive 278 from the inspection processing section 270 and into output processing section 280 (also referred to herein as rejection processing section) of the operations portion 250 of the BFS inspection machine 220.

Any or all of the components disclosed herein can be formed of one or more plastics. In some embodiments, some components (e.g., the BFS vials) can be formed of a relatively soft polymer (e.g., having a Shore/Durometer “D” hardness of between 60 and 70), such as polyethylene (e.g., low density polyethylene (LDPE)), polypropylene, or any other polymer adaptable for use in a BFS manufacturing process. In some embodiments, some components (e.g., the connection assemblies, the administration assemblies, and/or needle caps or covers) can be formed, at least in part, of a relatively hard polymer (e.g., having a hardness greater than 80 on the Rockwell “R” scale), such as, but not limited to, polypropylene, polycarbonate, polybenzimidazole, acrylonitrile butadiene styrene (ABS), polystyrene, polyvinyl chloride, or the like. Other materials are also possible according to one or more contemplated embodiments.
Throughout the description herein and unless otherwise specified, the following terms may include and/or encompass the example meanings provided. These terms and illustrative example meanings are provided to clarify the language selected to describe embodiments both in the specification and in the appended claims, and accordingly, are not intended to be generally limiting. While not generally limiting and while not limiting for all described embodiments, in some embodiments, the terms are specifically limited to the example definitions and/or examples provided. Other terms are defined throughout the present description.
Numerous embodiments are described in this patent application, and are presented for illustrative purposes only. The described embodiments are not, and are not intended to be, limiting in any sense. The presently disclosed invention(s) are widely applicable to numerous embodiments, as is readily apparent from the disclosure. One of ordinary skill in the art will recognize that the disclosed invention(s) may be practiced with various modifications and alterations, such as structural, logical, software, and electrical modifications. Although particular features of the disclosed invention(s) may be described with reference to one or more particular embodiments and/or drawings, it should be understood that such features are not limited to usage in the one or more particular embodiments or drawings with reference to which they are described, unless expressly specified otherwise.
The present disclosure is neither a literal description of all embodiments of the invention nor a listing of features of the invention that must be present in all embodiments.
Neither the Title (set forth at the beginning of the first page of this patent application) nor the Abstract (set forth at the end of this patent application) is to be taken as limiting in any way as the scope of the disclosed invention(s).
While the term “modules” is utilized herein for convenience and ease of illustration, objects represented and/or described as “modules” may comprise various forms, configurations, and/or quantities of components. A BFS module may comprise one or more BFS products that are formed and/or manufactured together or separately, for example, and/or may comprise one or more BFS chambers, bottles, containers, and/or other fluid-retaining objects. The term “module” does not convey any designation of shape or size. In some embodiments, a BFS module may comprise one or more vials. According to some embodiments a BFS module and/or a BFS vial may comprise one or more fluid chambers. In some embodiments, a plurality of BFS modules, components, vials, and/or chambers may be manufactured simultaneously from a single BFS mold. Each respective module and/or chamber may be formed, for example, by different portions of a single BFS mold (e.g., two cooperative halves thereof). In some embodiments, BFS modules, components, vials, and/or chambers may be joined and/or coupled during manufacturing (e.g., via unformed and/or fused connecting parison) and/or after manufacturing/filling.
The term “product” means any machine, manufacture and/or composition of matter as contemplated by 35 U.S.C. § 101, unless expressly specified otherwise.
The terms “an embodiment”, “embodiment”, “embodiments”, “the embodiment”, “the embodiments”, “one or more embodiments”, “some embodiments”, “one embodiment” and the like mean “one or more (but not all) disclosed embodiments”, unless expressly specified otherwise.
A reference to “another embodiment” in describing an embodiment does not imply that the referenced embodiment is mutually exclusive with another embodiment (e.g., an embodiment described before the referenced embodiment), unless expressly specified otherwise.
The terms “a”, “an” and “the” mean “one or more”, unless expressly specified otherwise.
The term “plurality” means “two or more”, unless expressly specified otherwise.
The term “herein” means “in the present application, including anything which may be incorporated by reference”, unless expressly specified otherwise.
The phrase “at least one of”, when such phrase modifies a plurality of things (such as an enumerated list of things) means any combination of one or more of those things, unless expressly specified otherwise. For example, the phrase at least one of a widget, a car and a wheel means either (i) a widget, (ii) a car, (iii) a wheel, (iv) a widget and a car, (v) a widget and a wheel, (vi) a car and a wheel, or (vii) a widget, a car and a wheel.
The phrase “based on” does not mean “based only on”, unless expressly specified otherwise. In other words, the phrase “based on” describes both “based only on” and “based at least on”.
Where a limitation of a first claim would cover one of a feature as well as more than one of a feature (e.g., a limitation such as “at least one widget” covers one widget as well as more than one widget), and where in a second claim that depends on the first claim, the second claim uses a definite article “the” to refer to the limitation (e.g., “the widget”), this does not imply that the first claim covers only one of the feature, and this does not imply that the second claim covers only one of the feature (e.g., “the widget” can cover both one widget and more than one widget).
Each process (whether called a method, algorithm or otherwise) inherently includes one or more steps, and therefore all references to a “step” or “steps” of a process have an inherent antecedent basis in the mere recitation of the term ‘process’ or a like term. Accordingly, any reference in a claim to a ‘step’ or ‘steps’ of a process has sufficient antecedent basis.
When an ordinal number (such as “first”, “second”, “third” and so on) is used as an adjective before a term, that ordinal number is used (unless expressly specified otherwise) merely to indicate a particular feature, such as to distinguish that particular feature from another feature that is described by the same term or by a similar term. For example, a “first widget” may be so named merely to distinguish it from, e.g., a “second widget”. Thus, the mere usage of the ordinal numbers “first” and “second” before the term “widget” does not indicate any other relationship between the two widgets, and likewise does not indicate any other characteristics of either or both widgets. For example, the mere usage of the ordinal numbers “first” and “second” before the term “widget” (1) does not indicate that either widget comes before or after any other in order or location; (2) does not indicate that either widget occurs or acts before or after any other in time; and (3) does not indicate that either widget ranks above or below any other, as in importance or quality. In addition, the mere usage of ordinal numbers does not define a numerical limit to the features identified with the ordinal numbers. For example, the mere usage of the ordinal numbers “first” and “second” before the term “widget” does not indicate that there must be no more than two widgets.
When a single device or article is described herein, more than one device or article (whether or not they cooperate) may alternatively be used in place of the single device or article that is described. Accordingly, the functionality that is described as being possessed by a device may alternatively be possessed by more than one device or article (whether or not they cooperate).
Similarly, where more than one device or article is described herein (whether or not they cooperate), a single device or article may alternatively be used in place of the more than one device or article that is described. For example, a plurality of computer-based devices may be substituted with a single computer-based device. Accordingly, the various functionality that is described as being possessed by more than one device or article may alternatively be possessed by a single device or article.
The functionality and/or the features of a single device that is described may be alternatively embodied by one or more other devices which are described but are not explicitly described as having such functionality and/or features. Thus, other embodiments need not include the described device itself, but rather can include the one or more other devices which would, in those other embodiments, have such functionality/features.
Devices that are in communication with each other need not be in continuous communication with each other, unless expressly specified otherwise. On the contrary, such devices need only transmit to each other as necessary or desirable, and may actually refrain from exchanging data most of the time. For example, a machine in communication with another machine via the Internet may not transmit data to the other machine for weeks at a time. In addition, devices that are in communication with each other may communicate directly or indirectly through one or more intermediaries.
A description of an embodiment with several components or features does not imply that all or even any of such components and/or features are required. On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the present invention(s). Unless otherwise specified explicitly, no component and/or feature is essential or required.
Further, although process steps, algorithms or the like may be described in a sequential order, such processes may be configured to work in different orders. In other words, any sequence or order of steps that may be explicitly described does not necessarily indicate a requirement that the steps be performed in that order. The steps of processes described herein may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to the invention, and does not imply that the illustrated process is preferred.
Although a process may be described as including a plurality of steps, that does not indicate that all or even any of the steps are essential or required. Various other embodiments within the scope of the described invention(s) include other processes that omit some or all of the described steps. Unless otherwise specified explicitly, no step is essential or required.
Although a product may be described as including a plurality of components, aspects, qualities, characteristics and/or features, that does not indicate that all of the plurality are essential or required. Various other embodiments within the scope of the described invention(s) include other products that omit some or all of the described plurality.
An enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are mutually exclusive, unless expressly specified otherwise. Likewise, an enumerated list of items (which may or may not be numbered) does not imply that any or all of the items are comprehensive of any category, unless expressly specified otherwise. For example, the enumerated list “a computer, a laptop, a PDA” does not imply that any or all of the three items of that list are mutually exclusive and does not imply that any or all of the three items of that list are comprehensive of any category.
Headings of sections provided in this patent application and the title of this patent application are for convenience only, and are not to be taken as limiting the disclosure in any way.
“Determining” something can be performed in a variety of manners and therefore the term “determining” (and like terms) includes calculating, computing, deriving, looking up (e.g., in a table, database or data structure), ascertaining and the like
The terms “including”, “comprising” and variations thereof mean “including but not limited to”, unless expressly specified otherwise. As used herein, “comprising” means “including,” and the singular forms “a” or “an” or “the” include plural references unless the context clearly dictates otherwise. The term “or” refers to a single element of stated alternative elements or a combination of two or more elements, unless the context clearly indicates otherwise
A description of an embodiment with several components or features does not imply that all or even any of such components and/or features are required. On the contrary, a variety of optional components are described to illustrate the wide variety of possible embodiments of the present invention(s). Unless otherwise specified explicitly, no component and/or feature is essential or required.
Further, although process steps, algorithms or the like may be described in a sequential order, such processes may be configured to work in different orders. In other words, any sequence or order of steps that may be explicitly described does not necessarily indicate a requirement that the steps be performed in that order. The steps of processes described herein may be performed in any order practical. Further, some steps may be performed simultaneously despite being described or implied as occurring non-simultaneously (e.g., because one step is described after the other step). Moreover, the illustration of a process by its depiction in a drawing does not imply that the illustrated process is exclusive of other variations and modifications thereto, does not imply that the illustrated process or any of its steps are necessary to the invention, and does not imply that the illustrated process is preferred.
The present disclosure provides, to one of ordinary skill in the art, an enabling description of several embodiments and/or inventions. Some of these embodiments and/or inventions may not be claimed in the present application, but may nevertheless be claimed in one or more continuing applications that claim the benefit of priority of the present application. Applicants intend to file additional applications to pursue patents for subject matter that has been disclosed and enabled but not claimed in the present application.
It will be understood that various modifications can be made to the embodiments of the present disclosure herein without departing from the scope thereof.

All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.
The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”
The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified, unless clearly indicated to the contrary.
Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
The disclosure of numerical ranges should be understood as referring to each discrete point within the range, inclusive of endpoints, unless otherwise noted. Unless otherwise indicated, all numbers expressing quantities of components, molecular weights, percentages, temperatures, times, and so forth, as used in the specification or claims are to be understood as being modified by the term “about.” Accordingly, unless otherwise implicitly or explicitly indicated, or unless the context is properly understood by a person of ordinary skill in the art to have a more definitive construction, the numerical parameters set forth are approximations that may depend on the desired properties sought and/or limits of detection under standard test conditions/methods, as known to those of ordinary skill in the art. When directly and explicitly distinguishing embodiments from discussed prior art, the embodiment numbers are not approximates unless the word “about” is recited. Whenever “substantially,” “approximately,” “about,” or similar language is explicitly used in combination with a specific value, variations up to and including ten percent (10%) of that value are intended, unless explicitly stated otherwise.
Directions and other relative references may be used to facilitate discussion of the drawings and principles herein, but are not intended to be limiting. For example, certain terms may be used such as “inner,” “outer,”, “upper,” “lower,” “top,” “bottom,” “interior,” “exterior,” “left,” right,” “front,” “back,” “rear,” and the like. Such terms are used, where applicable, to provide some clarity of description when dealing with relative relationships, particularly with respect to the illustrated embodiments. Such terms are not, however, intended to imply absolute relationships, positions, and/or orientations. For example, with respect to an object, an “upper” part can become a “lower” part simply by turning the object over. Nevertheless, it is still the same part and the object remains the same.
The terms and expressions which have been employed herein are used as terms of description and not of limitation, and there is no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described (or portions thereof), and it is recognized that various modifications are possible within the scope of the claims. Accordingly, the claims are intended to cover all such equivalents.
Any of the features illustrated or described with respect to
Various modifications of the invention and many further embodiments thereof, in addition to those shown and described herein, will become apparent to those skilled in the art from the full contents of this document, including references to the scientific and patent literature cited herein. The subject matter herein contains important information, exemplification and guidance that can be adapted to the practice of this invention in its various embodiments and equivalents thereof.
