The present invention relates to a digital health proxy device, system, and method. or particularly, but not exclusively, the various apparatuses, methods, and systems disclosed herein relate to a health proxy device configured to parse medical data using data processing techniques and provide assistive technologies to a caregiver and/or patient for making an optimal medical decision in a time-sensitive environment.
For informal caregivers (ICG), accompanying their loved one (e.g., a child or an elder loved one) to the emergency department during an acute event can be a stressful, frightening and overwhelming time. The informal caregiver may need to be the voice of the patient even if he or she does not understand the situation fully themselves. Because of this, informal caregivers rely heavily on the direction of the physician and the physician recommendations, which may or may not be the correct course of action for the care recipient.
To the extent a caregiver relies upon additional resources, those resources may simply be generic websites such as medical and/or health news and publications (e.g., WebMD®). However, parsing through online and/or printed materials is time-consuming and ineffective in time-sensitive scenarios such as the acute care setting. Additionally, the information may not be available in a manner that is easily understood by a lay person and therefor is an ineffective resource for many individuals. Accordingly, by relying solely on a medical professional, a caregiver may not be thoroughly aware of alternative testing, diagnosis or treatment options. And, as a result, a caregiver may not be able to identify the best testing, diagnosis, and/or treatment options specific to the care recipient based at least on the care recipient's specific medical history.
In addition, current systems and devices lack the ability to provide medically secure assistance and optimized assistive technology. For example, a device that may operate the assistive technology may include a caregiver device that may at times remain unsecured (e.g., unlocked, open to public wireless networks, and/or the like). It is estimated that about 250,000 people die in the United States alone due to medical errors every year. Given an advanced medical proxy device with at least enhanced medical databasing and an improved processing technologies as described herein, these drawbacks in current technologies may be addressed so that caregivers may gather diagnosis, treatment, protocol, and clinical data and/or determine an optimal treatment plan for the care recipient.
The present disclosure is directed to inventive methods and apparatus for a device, system, and methods that provide health proxy technologies. Generally, in one aspect a caregiver device is disclosed where the caregiver device includes an antenna that communicates wirelessly with a network; an input/output interface comprising a display; and a processor that: receives an indication to begin a medical guidance session; transmits, via the antenna and in response to receiving an indication to begin a medical guidance session, a request to generate a dynamic database comprising patient specific data, population-based clinical data, and medical ontology data, wherein the dynamic database is dynamically reduced in response to each query to the dynamic database during the medical guidance session; receives current patient event data comprising a treatment recommendation and at least one of: diagnosis data, clinical notes, and image data; executes a query process comprising: querying the dynamic database using the current patient event data to identify a refined dataset used to determine (a) a preliminary treatment confidence associated with the treatment recommendation and (b) additional data that could increase the preliminary treatment confidence; generating a question for the user, wherein the question is associated with the determined additional data; receiving a response to the generated question via the input/output interface; and determining an updated treatment confidence associated with the treatment recommendation; and transmits, via the input/output interface, caregiver data comprising at least one of: the updated treatment confidence and a description of the treatment recommendation associated with the medical guidance session.
In some aspects of the invention the processor further determines a security setting based on network settings associated with the network, and wherein the indication to begin a medical guidance session comprises a security feature based on the security setting comprising at least one of: a username, a password, a personal identification number (PIN), and a biometric data.

Generally, in some aspects of the invention the patient specific data comprises patient insurance data, and wherein at least one of the preliminary treatment confidence and updated treatment confidence is based on the patient insurance data, and wherein the generated question is related to the patient insurance data.
In some aspects of the inventions, a device may further comprise a location detection unit that detects a location of the device, wherein when the location of the device is within a predefined distance of a medical facility, the processor generates a notification to begin the medical guidance session prior to receiving an indication to begin the medical guidance session. In still other aspects of the invention, when the location detection unit determines the location of the device is within a predefined distance of a medical facility, the device generates a notification to alter a network setting, wherein the notification comprises selectable data to automatically alter the network setting.
Generally, in some aspects of the invention, a device may further comprise a camera, wherein image data is received via the camera. In still other aspects of the invention, a treatment recommendation may comprise at least two treatment options, and wherein the preliminary treatment confidence comprises a treatment option confidence for each treatment option, and wherein the determined additional data could increase the treatment option confidence for at least one of the treatment options.
In some aspects, a device may further comprise a memory whereby the dynamic database is cached in the memory. Generally, in some aspects of the invention the dynamic database may be cached upon reaching a predefined size. In still some aspects of the invention, the antenna may become inactive once the dynamic database is cached on the device.

In various embodiments, load balancer(s) 210 may distribute workloads across, for example, web server(S) 216 and/or backend 218 systems. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any one of the resources. Using multiple components with load balancing instead of a single component may increase reliability through redundancy. Load balancing is usually provided by dedicated software or hardware, such as a multilayer switch or a Domain Name System (DNS) server process.
Load balancer(s) 208 may include software that monitoring the port where external clients, such as, for example, cardholder device 202, connect to access various services of a financial institution, for example. Load balancer(s) 208 may forward requests to one of the application servers 216 and/or backend 218 servers, which may then reply to load balancer 208. This may allow load balancer(s) 208 to reply to cardholder device 202 without cardholder device 202 ever knowing about the internal separation of functions. It also may prevent cardholder devices from contacting backend servers directly, which may have security benefits by hiding the structure of the internal network and preventing attacks on backend 218 or unrelated services running on other ports, for example.
A variety of scheduling algorithms may be used by load balancer(s) 208 to determine which backend server to send a request to. Simple algorithms may include, for example, random choice or round robin. Load balancers 208 also may account for additional factors, such as a server's reported load, recent response times, up/down status (determined by a monitoring poll of some kind), number of active connections, geographic location, capabilities, or how much traffic it has recently been assigned.
Load balancers 208 may be implemented in hardware and/or software. Load balancer(s) 208 may implement numerous features, including, without limitation: asymmetric loading; Priority activation: SSL Offload and Acceleration; Distributed Denial of Service (DDoS) attack protection; HTTP/HTTPS compression; TCP offloading; TCP buffering; direct server return; health checking; HTTP/HTTPS caching; content filtering; HTTP/HTTPS security; priority queuing; rate shaping; content-aware switching; client authentication; programmatic traffic manipulation; firewall; intrusion prevention systems.
Web server(s) 210 may include hardware (e.g., one or more computers) and/or software (e.g., one or more applications) that deliver web content that can be accessed by, for example a client device (e.g., cardholder device 202) through a network (e.g., network 204), such as the Internet. In various examples, web servers, may deliver web pages, relating to, for example, health proxy assistance sessions, to clients (e.g., user device 202). Web server(s) 210 may use, for example, a hypertext transfer protocol (HTTP/HTTPS or sHTTP) to communicate with user device 202. The web pages delivered to user device may include, for example, HTML documents, which may include images, style sheets and scripts in addition to text content.
A user agent, such as, for example, a web browser, web crawler, or native mobile application, may initiate communication by making a request for a specific resource using HTTP/HTTPS and web server 210 may respond with the content of that resource or an error message if unable to do so. The resource may be, for example a file on stored on backend 218. Web server(s) 210 also may enable or facilitate receiving content from user device 202 so user device 202 may be able to, for example, submit network-based forms, including uploading of files.
Web server(s) also may support server-side scripting using, for example, Active Server Pages (ASP), PHP, or other scripting languages. Accordingly, the behavior of web server(s) 210 can be scripted in separate files, while the actual server software remains unchanged.
Load balancers 214 may be similar to load balancers 208 as described above.
Application server(s) 216 may include hardware and/or software that is dedicated to the efficient execution of procedures (e.g., programs, routines, scripts) for supporting its applied applications. Application server(s) 216 may comprise one or more application server frameworks, including, for example, Java application servers (e.g., Java platform, Enterprise Edition (Java EE), the .NET framework from Microsoft®, PHP application servers, and the like). The various application server frameworks may contain a comprehensive service layer model. Also, application server(s) 216 may act as a set of components accessible to, for example, a decision engine and/or medical facility system or other entity implementing system 200, through an API defined by the platform itself. For Web applications, these components may be performed in, for example, the same running environment as web server(s) 210, and application servers 216 may support the construction of dynamic pages. Application server(s) 216 also may implement services, such as, for example, clustering, fail-over, and load-balancing. In various embodiments, where application server(s) 216 are Java application servers, the web server(s) 216 may behaves like an extended virtual machine for running applications, transparently handling connections to databases associated with backend 218 on one side, and, connections to the Web client (e.g., client device 202) on the other.
Backend 218 may include hardware and/or software that enables the backend services of, for example, a decision engine and/or medical facility system or other entity that maintains a distributed system similar to system 200. For example, backend 218 may include, a system of one or more platforms that provide mobile services, one or more platforms that provide online services, a decision engine platform, and/or a location system, which may include additional capabilities, such as determining the location of a user device 202 and its proximity to a medical facility. Backend 218 may be associated with various databases, including data storage such as data storage 130. Backend 218 also may be associated with one or more servers that enable the various services provided by system 200.
Referring now to
The mobile device 300 comprises at least two different processors, including a baseband processor (BBP) 304 and an application processor (APP) 308. As is known, the baseband processor 304 primarily handles baseband communication-related tasks and the application processor 308 generally handles inputs and outputs and all applications other than those directly related to baseband processing. The baseband processor 304 comprises a dedicated processor for deploying functionality associated with a protocol stack, such as but not limited to a GSM (Global System for Mobile communications) protocol stack, among other functions. The application processor 308 comprises a multi-core processor for running applications, including all or a portion of application software. The baseband processor 304 and the application processor 308 have respective associated memory including random access memory (RAM), Flash memory, etc., and peripherals, and a running clock. The memory are each also referred to herein as a non-transitory computer readable medium. Note that, though depicted as residing in memory 310, all or a portion of the application software may be stored in memory 310, distributed among memory or reside in other memory.
The baseband processor 304 may deploy functionality of the protocol stack to enable the mobile device 300 to access one or a plurality of wireless network technologies, including WCDMA (Wideband Code Division Multiple Access), CDMA (Code Division Multiple Access), EDGE (Enhanced Data Rates for GSM Evolution), GPRS (General Packet Radio Service), Zigbee (e.g., based on IEEE 802.15.4), Bluetooth, Wi-Fi (Wireless Fidelity, such as based on IEEE 802.11), and/or LTE (Long Term Evolution), among variations thereof and/or other telecommunication protocols, standards, and/or specifications. The baseband processor 304 manages radio communications and control functions, including signal modulation, radio frequency shifting, and encoding. The baseband processor 304 comprises, or may be coupled to, a radio (e.g., RF front end) 302 and/or a GSM (or other communications standard) modem, and analog and digital baseband circuitry (ABB, DBB, receptively). The radio 302 comprises one or more antennas, a transceiver, and a power amplifier to enable the receiving and transmitting of signals of a plurality of different frequencies, enabling access to a cellular (and/or wireless) network. The analog baseband circuitry is coupled to the radio 302 and provides an interface between the analog and digital domains of the GSM modem. The analog baseband circuitry comprises circuitry including an analog-to-digital converter (ADC) and digital-to-analog converter (DAC), as well as control and power management/distribution components and an audio codec to process analog and/or digital signals received indirectly via the application processor 308 or directly from a user interface (UI) 318 (e.g., microphone, earpiece, ring tone, vibrator circuits, touch-screen, etc.). The ADC digitizes any analog signals for processing by the digital baseband circuitry. The digital baseband circuitry deploys the functionality of one or more levels of the GSM protocol stack (e.g., Layer 1, Layer 2, etc.), and comprises a microcontroller (e.g., microcontroller unit or MCU, also referred to herein as a processor) and a digital signal processor (DSP, also referred to herein as a processor) that communicate over a shared memory interface (the memory comprising data and control information and parameters that instruct the actions to be taken on the data processed by the application processor 308). The MCU may be embodied as a RISC (reduced instruction set computer) machine that runs a real-time operating system (RTIOS), with cores having a plurality of peripherals (e.g., circuitry packaged as integrated circuits) such as RTC (real-time clock), SPI (serial peripheral interface), I2C (inter-integrated circuit), UARTs (Universal Asynchronous Receiver/Transmitter), devices based on IrDA (Infrared Data Association), SD/MMC (Secure Digital/Multimedia Cards) card controller, keypad scan controller, and USB devices, GPRS crypto module, TDMA (Time Division Multiple Access), smart card reader interface (e.g., for the one or more SIM (Subscriber Identity Module) cards), timers, and among others. For receive-side functionality, the MCU instructs the DSP to receive, for instance, in-phase/quadrature (I/Q) samples from the analog baseband circuitry and perform detection, demodulation, and decoding with reporting back to the MCU. For transmit-side functionality, the MCU presents transmittable data and auxiliary information to the DSP, which encodes the data and provides to the analog baseband circuitry (e.g., converted to analog signals by the DAC).
The application processor 308 operates under control of an operating system (OS) that enables the implementation of a plurality of user applications, including, for example, the application software that supports a health proxy assistance session. The application processor 308 may be embodied as a System on a Chip (SOC), and supports a plurality of multimedia related features including web browsing/cloud-based access functionality to access one or more computing devices, of the cloud(s), that are coupled to the Internet. For instance, the application processor 308 may execute communications functionality of the application software (e.g., middleware, similar to some embodiments of the caregiver device 120 which may include a browser with or operable in association with one or more application program interfaces (APIs)) to enable access to a cloud computing framework or other networks to provide remote data access/storage/processing, and through cooperation with an embedded operating system, access to calendars, location services, user data, public data, caregiver observation data, care recipient medical data, etc.
For instance, in some embodiments, the health proxy assistance system may operate using cloud computing services, where the processing of raw and/or derived parameter data received, indirectly via the mobile device 300 or directly from the caregiver device 120, data storage 130, and/or medical provider system 140 may be achieved by one or more devices of the cloud(s), and triggering signals (to trigger feedback) may be communicated from the cloud(s) (or other devices) to the mobile device 300, which in turn may activate feedback internal to the mobile device 300 (e.g., visually, audibly, or via tactile mechanisms) or relay the triggering signals to other devices (e.g., medical provider system 140, decision engine 150).
The application processor 308 generally comprises a processor core (Advanced RISC Machine or ARM), and further comprises or may be coupled to multimedia modules (for decoding/encoding pictures, video, and/or audio), a graphics processing unit (GPU), communications interface 328, and device interfaces. In one embodiment, the communications interfaces 328 may include wireless interfaces, including a Bluetooth (BT) (and/or Zigbee in some embodiments, among others) module that enable wireless communication with the data storage 130, medical provider system 140, and/or decision engine 140.
In some embodiments, the communications interface 328 may comprise a Wi-Fi module for interfacing with a local 802.11 network, according to corresponding communications software in the applications software. The application processor 308 further comprises, or in the depicted embodiment, is coupled to, a global navigation satellite systems (GNSS) receiver 330 for enabling access to a satellite network to, for instance, provide position coordinates. In some embodiments, the GNSS receiver 330, in association with GNSS functionality in the application software, collects contextual data (time and location data, including location coordinates and altitude) to determine a proximity to a medical facility for example. Note that, though described as a GNSS receiver 330, other indoor/outdoor positioning systems may be used, including those based on triangulation of cellular network signals and/or Wi-Fi.
The device interfaces coupled to the application processor 308 may include the user interface 318, including a display screen. The display screen, in some embodiments similar to a display screen of the wearable device user interface, may be embodied in one of several available technologies, including LCD or Liquid Crystal Display (or variants thereof, such as Thin Film Transistor (TFT) LCD, In Plane Switching (IPS) LCD)), light-emitting diode (LED)-based technology, such as organic LED (OLED), Active-Matrix OLED (AMOLED), retina or haptic-based technology, or virtual/augmented reality technology. For instance, the user interface 318 may present visual feedback in the form of messaging (e.g., text messages) and/or symbols/graphics (e.g., warning or alert icons, flashing screen, etc.), and/or flashing lights (LEDs). In some embodiments, the user interface 318 may be configured, in addition to or in lieu of a display screen, a keypad, microphone, speaker, ear piece connector, I/O interfaces (e.g., USB (Universal Serial Bus)), SD/MMC card, among other peripherals. For instance, the speaker may be used to audibly provide feedback, and/or the user interface 318 may comprise a vibratory motor that provides a vibrating feedback to the user. One or any combination of visual, audible, or tactile feedback may be used, and as described before, variations in the intensity of format of the feedback may be used.
Also coupled to the application processor 308 is an image capture device (IMAGE CAPTURE) 326. The image capture device 326 may comprise an optical sensor (e.g., a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor). The image capture device 326 may be configured to capture and/or receive medical imaging, such as ultrasounds and/or other scans.
Also included is a power management device 322 that controls and manages operations of a battery 324. The components described above and/or depicted in
In the depicted embodiment, the application processor 308 runs the application software 314, and may comprise a conversation detection application 315, a feedback application 316, and a communications application 317. The conversation detection application 315 may, upon receiving an indication to begin a healthy proxy assistance session, execute voice recognition processes to detect a caregiver voice and a medical professional (or other) voice. Conversation detection application 315 may use natural language processing techniques to parse the language spoked by the medical professional to determine any medical data (testing results, vital signs, emergency medication provision, and/or the like) associated with a care recipient medical event. This data may then be used by a decision engine to successfully execute a health proxy assistance session. Conversation detection application 315 may also receive input via an interface in the form of alphanumeric input, imaging input, and/or the like to detect and determine relevant medical data for a health proxy assistance session.
The feedback application provides for visual, audible, and or tactile feedback to the user via the user interface 318. The communications interface 328 communicates raw and/or derived parameters to one or more other devices such as data storage 130, medical provider system 140, and/or decision engine 150, and also receives triggering signals to activate the feedback functionality. For instance, in one embodiment, the mobile device 300 communicates parameters to the data storage 130 and/or decision engine 150 and receives feedback from these system components.
At block 404, a system may receive an indication to begin a medical guidance or health proxy assistance session. The indication may be received in response to manual input via an input/output interface on a caregiver device. The indication may be receive in response to a prompt and/or push notification generated upon the caregiver device detecting a proximity to a medical facility. Caregiver device may detect proximity to a medical facility by determining that a caregiver device is within a predefined distance of a medical facility using location detection technology and/or proximity data received from a medical facility device (e.g., Bluetooth, BLE, RFID WiFi and/or other network data indicating network data of a medical facility). The indication may be received automatically upon a caregiver device detecting a proximity to a medical facility.
Upon receiving an indication to begin a health proxy assistance session, a security setting may be determined associated with the caregiver device. A security setting may be based on network settings associated with the network connected to the caregiver device. An indication to begin a health proxy assistance session may include transmitting a security feature based on the security setting comprising at least one of: a username, a password, a personal identification number (PIN), and a biometric data. Moreover, prior to and/or in conjunction with receiving the indication to begin the medical guidance session, a caregiver device may receive a notification to change a network setting to increase security. By way of example, a caregiver device may receive a notification to leave a wide area network and join a local area network. Caregiver device may automatically resume prior network settings once a health proxy assistance session ends.
At block 406, a caregiver device may transmit a request to generate a dynamic database. For example, a caregiver device, such as caregiver device 120 may query data storage such as data storage 130 to determine care recipient-specific data as well as medical event specific data and/or population-specific data. For example, where a care recipient has suffered a particular medical event, data associated with that particular event (agnostic to the care recipient) may be retrieved and/or population-based clinical data, such as data specific to demographically-similar and/or medically-similar patients may be retrieved to generate a dynamic database for a particular health proxy assistance session. Dynamic database may further include ontology data, such as data relevant to the current care recipient medical event from a Medical Subject Headings (MeSH) knowledge base, Unified Medial Language System (UMLS), and/or the Online Mendelian Inheritance in Man (OMIM) knowledge bases. Dynamic database may further include patient-centric data relevant to the current care recipient medical event such as prior medical records, caregiver observation data, PERS data, care recipient wearable device data (fall detection data, vital signs data, stress data, activity data, and/or the like), medication adherence data, and/or current or prior medication data. Dynamic database may also include patient specific data such as patient insurance data.
Once relevant data is retrieved from population-based clinical data, ontology data, and patient-centric data, the data may be combined into a dynamic database that is cached in memory, for example of the decision engine, during the healthy proxy assistance session until it is written into memory (of a prior iterations database, caregiver device memory, medical provider system memory and/or decision engine).
While a dynamic database is being generate, a caregiver device may receive current patient event data at block 408 from a medical professional and/or a medical provider system. Current patient event data may include voice data from a medical professional detailing the medical event, testing and/or examination results, treatment recommendation(s), and/or diagnosis. Current patient event data may include medical testing and/or imaging results. Current patient event data may include real-time vital signs measurements. A dynamic database may be continuously generated upon receipt of each data point associate with the current patient event data.
At block 410, the dynamic database may be queried to determine a confidence interval associated with a diagnosis and/or treatment recommendation using, for example, statistical confidence, matched cases, and/or machine learning techniques such as decision trees, neural networks (e.g., artificial neural networks, ANN), deep learning, support vector machines (SVMs), clustering, Bayesian networks, and/or the like. In this way, a diagnosis and/or treatment recommendation may be associated with a confidence interval. Decision engine may then determine additional data that may increase the confidence level associated with a particular diagnosis and/or treatment option by altering the variables of the matched cases, determining which variable changes may increase the confidence level, and selecting the variable that make the most impact on a confidence level. An additional data request may be generated using natural language processing to generate a caregiver-level question and/or request for information to be answered by the medical professional. A caregiver-level may be determined to include medical terminology as well as a descriptive terminology that explains the medical terminology. By way of example, a natural language processing technique may be used to replace medical terminology, such as transient ischemic attack, with more descriptive terminology, such as deprive blood flow to the brain. In this manner, the caregiver may be able to ask questions and receive information that the caregiver is able to comprehend.
By way of example, a diagnosis of Congestive Heart Failure (CHF) may be originally provided and a treatment recommendation may be fluid removal. Upon querying the dynamic database it may be determined that pulmonary consult test result data is a variable that would most alter a confidence of the diagnosis and/or treatment recommendation. Accordingly, the decision engine may generate a question to determine if the treatment may be altered to include a pulmonary consult test. Upon receiving test results, the decision engine may query the dynamic database with the updated information and determine a lower confidence of the original diagnosis and treatment and a higher confidence of an alternate diagnosis (e.g., pulmonary embolism) and treatment (e.g., blood thinning treatment). The natural language processor may explain what a pulmonary consult test is and generate a question to ask if the patient can receive that test.
At block 412, a response may be received to the additional data request. In the example above, the response may be a doctor explaining the results of the test to the caregiver and/or the actual result data itself. Additional data request may include data relevant to the care recipient or patient's insurance. In block 414, an updated treatment confidence may be determined. In the example above, it may be determined that the treatment confidence for CFH is lower and the treatment confidence for a pulmonary embolism is higher.
At block 416, caregiver data may be transmitted to the caregiver via the caregiver device. For example, caregiver data may include an explanation of the diagnosis, an explanation of the treatment recommendation, a treatment and/or diagnosis confidence, and/or links for additional data regarding the diagnosis and/or treatment.
At block 418, the method may end.
It is further noted that the systems and methods described herein may be tangibly embodied in one of more physical media, such as, but not limited to, a compact disc (CD), a digital versatile disc (DVD), a floppy disk, a hard drive, read only memory (ROM), random access memory (RAM), as well as other physical media capable of storing software, or combinations thereof. Moreover, the figures illustrate various components (e.g., servers, computers, processors, etc.) separately. The functions described as being performed at various components may be performed at other components, and the various components bay be combined or separated. Other modifications also may be made.
The present disclosure is not to be limited in terms of the particular embodiments described in this application, which are intended as illustrations of various aspects. Many modifications and variations can be made without departing from its spirit and scope, as may be apparent. Functionally equivalent methods and apparatuses within the scope of the disclosure, in addition to those enumerated herein, may be apparent from the foregoing representative descriptions. Such modifications and variations are intended to fall within the scope of the appended representative claims. The present disclosure is to be limited only by the terms of the appended representative claims, along with the full scope of equivalents to which such representative claims are entitled. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It may be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It may be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent may be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to embodiments containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, such recitation should be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It may be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” may be understood to include the possibilities of “A” or “B” or “A and B.”
The foregoing description, along with its associated embodiments, has been presented for purposes of illustration only. It is not exhaustive and does not limit the invention to the precise form disclosed. Those skilled in the art may appreciate from the foregoing description that modifications and variations are possible in light of the above teachings or may be acquired from practicing the disclosed embodiments. For example, the steps described need not be performed in the same sequence discussed or with the same degree of separation. Likewise various steps may be omitted, repeated, or combined, as necessary, to achieve the same or similar objectives. Accordingly, the invention is not limited to the above-described embodiments, but instead is defined by the appended claims in light of their full scope of equivalents.
In the preceding specification, various preferred embodiments have been described with references to the accompanying drawings. It may, however, be evident that various modifications and changes may be made thereto, and additional embodiments may be implemented, without departing from the broader scope of the invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded as an illustrative rather than restrictive sense.
