The example embodiments in general are directed to a door locking apparatus, more particularly to an apparatus adapted to provide resistance to a forced entry through the door.
It may be desirable in many situations to increase the security on a door by, for example, installing a stronger lock or additional locks or bolts at additional locking points around the door. However, it is not always possible or convenient to make these types of permanent installations on a door, for example in a rented home or office, a hotel or hostel room, or in student accommodations.
Thus, in these situations it may be desirable to increase door security using non-permanent means. One well known method is to jam a chair under the door handle, but unless the chair is of proper size and construction, this will not hold the door for long. Another solution of jamming a door closed is by locating a bar at an angle between the door handle and the floor behind the door. While this is an improvement over the use of a chair, the connection between the bar and the door handle is prone to failure, and the bar can extend significantly beyond the door, presenting a trip hazard.
One conventional improvement to the angled bracing bar noted above is shown in
With brace 10 in its extended condition, the foot 17 engages the floor 16 and prevents the door 14 from swinging to the left. This is accomplished by an internal motor 19 supplied with electrical current from batteries 29. As is well known, the DC motor 19 under power from batteries 29 extends and retracts the inner tube 12 within outer tube 13, so as to raise and lower foot 17. Motor 19 is connected to a gear reduction unit 32 with a recess 33 to receive a splined shaft 34 projecting from the lower tube 13. The splined shaft is rotated by the reduction gears 32 and it is connected to a threaded shaft 36 which threads into a non-rotatable nut 37 secured to the upper end of the inner tube 12. The inner tube 12 (and the nut 37) are prevented from rotating by a pin 38 projecting from the inner tube 12 into a longitudinal slot 39 in the outer tube 13.
The motor 19 is controlled by a radio receiver and associated electronics 21 which may be an off-the shelf arming and disarming circuits. As this brace 10 was developed pre-internet and prior to the smart phone age, coded radio signals are employed. Namely, coded radio waves are sent directly to a radio receiver 21 by a hand held transmitter (not shown). When the code supplied by the transmitter is identical to the code recognized by the receiver 21, the brace 10 under motor 19 control will extend or retract inner tube 12 with the foot 17 attached to the distal end thereof, depending upon the state of a flip-flop in the electronics of the receiver 21.
A more current, commercially available conventional door brace, known as the DOORJAMMER™ (sold by Gitway, Inc.) is shown in
The leg 20 comprises a fixed length section 22 and an adjustable length section 24′. In this embodiment, the fixed length section 22 has an angled shape and comprises a first part 22a and a second part 22b. The first part 22a extends in a first elongate direction and the second part 22b extends in the second elongate direction. In the bracing position, the first part 22a extends at a first angle to the face 18′ and the second part 22b extends at a second, smaller angle to the face 18′.
The leg 20 is hingedly connected at one end of its first part 22a to the opposite face of the engagement wall 16′, so as to be moveable relative to the door engagement member 12′ between a bracing position (as shown) and a released position. In the bracing position the leg 20 is spaced from the engagement wall 16′ and in the released position the foot 26′ is located generally adjacent to the engagement wall 16′.
The adjustable length section 24′ of leg 20 is embodied as a threaded bolt located in a threaded aperture within the second part 22b. The adjustable length section 24′ includes a wing nut 28′ for turning the threaded bolt into or out of the fixed length section 22 to shorten or lengthen the adjustable length section 24′. The foot 26′ is provided with a pad 32′ of non-slip material to provide additional resistance to force applied to the door brace 20′.
In use, with the door brace 10′ in its released condition the bottom flange 14′ is underneath the door 34′ and the door brace 10′ is pushed towards the door 34′ until the face 18′ of the engagement wall 16′ is located against part of one side of the door 34′. The leg 20 is then moved from the released to the bracing position, whereby the length of the adjustable length section 24′ is increased by turning the wing-nut 28′, and the non-slip pad 32′ on the foot 26′ contacts the floor 36′. In this position a force applied against the door 34 on the side opposite to the one on which the door brace 10′ is located is transferred into the door brace 10′, and a downwards component of the force is exerted downwardly through the leg 20′ and the foot 26′ into the floor 36′. Any external force on the door 34′ increases the strength of the engagement of the door brace 10′ between the door 34′ and the floor 36′.
Applicant, in its co-pending parent '746 application, described two (2) conventional door locking apparatuses, as shown in
The housing 110 includes an interior metal backing 112, a pair of interior upper support ribs 114, a pair of lower, spaced interior support ribs 117, an access cover 116 on a sloping front facing 113 for access to various components therein. Housing 110 includes a bottom horizontal flange 115 that is designed so as to be located under a bottom edge of the door 105, in a space between the door bottom edge and the floor surface 107. This facilitates orienting and securing a rear face 111 of housing 110 flush against the door 105.
Additionally, apparatus 100 includes attachment means embodied as one or more suction cups 195 to removably attach the rear face 111 of the housing 110 to a portion of the opposite-facing door 105. As shown in
Within housing 110, a DC-powered linear actuator 150 is adapted to actuate a movable foot 170. The actuator 150 comprises a DC motor 153, the lead screw (not shown, within screw housing 154) and a traveler rod 155, which has a proximal end connected to a nut traveling on the lead screw (not shown, within a screw housing 154) and a distal end attached to foot 170 between posts 171 thereof.
An upper end 151 of the actuator 150 is fixed between the upper support ribs 114 via a metal pin 118 such as a cotter pin, and the actuator lower end 152 is connected to a horizontal connecting rod 160 attached at one end via pin 161 between lower support ribs 117, and at its other end to the screw housing 154, which extends through aperture 162, The movable foot 170 is attached to a lower end 152 of the actuator 150. Foot 170 includes posts 171 connected to the actuator lower end 152 by a pair of metal mounting pins 172, which also serve to secure an end of a metal horizontal connecting rod 160. Foot 170 includes an elastomeric bottom pad 173 that, with the foot 170 in the lock state, provides a frictional surface against the floor surface 107 to facilitate maintaining the door 105 in place.
As described in the '746 application, for actuator 150 the DC motor 153 is configured to receive a current signal from an electronics module 180 via a power source 130 within the housing 110, to either extend of retract foot 170. Namely, based on the signal, a lead screw (within the screw housing 154) rotatable in two directions under control of the DC motor 153 translates rotary motion thereof to a linear displacement, the lead screw having a continuous helical thread on its circumference running along a length thereof, and a nut (not shown) which travels on the threads of the lead screw but does not rotate with the lead screw, the nut having corresponding helical threads threaded on the lead screw. The nut is adapted to be driven along the threads of the lead screw as the lead screw rotates in a first direction so that the traveler rod 155 and attached foot 170 extend (upon a lock state signal being received), or is adapted to be driven as the lead screw rotates in a second direction so that the traveler rod 155 and attached foot 170 retract (upon an unlock state signal being received). Accordingly, in the locked state, any external force on the door 105 increases the strength of the engagement of the apparatus 100 between the door 105 and the floor 107.
As described in detail in the '746 application, movement of the foot 170 by the DC-powered actuator 150 is based on a remote, wireless signal sent from a smart device (not shown, but embodied as any of a cell phone, smart pad, key fob and the like) and received by an electronics module 180 (configured in an example as a printed circuit board assembly (PCBA)) that is configured to communicate wirelessly with the remote smart device in order to control the powered actuator 150.
Housing 110 includes indicator lamps thereon such as LEDs for example, here shown as a lamp 120 that when illuminated may indicate that the apparatus 100 is paired (via a short wave radio signal such as BLUETOOTH, Wi-Fi, etc.) with the smart device, or actively in a charging mode, fully charged, and/or also as an indication of an intruder alert. Another lamp 121 can represent a battery level low or battery charging indicator, and/or also be an indication of an intruder alert. Housing 110 includes a charging port 181 adapted for receiving external DC power thereto from a cable, such as a cable connected to DC wall power.
The indicator lamps 120, 121, actuator 150 and electronics module 180 are powered by a power supply 130, such as one or more alkaline or rechargeable batteries 132. A user may electrically connect the power source 130 to other electrical components therein by simply pressing a power (on/off) button 131, which extends through aperture 123 in housing 110. The on/off button 131 when pressed electrically connects the electronics module 180 to battery power via power source 130 thereto via a tach switch 182.
Here, movement of the foot 170′ to secure door 105 is powered by the AC motor 150′, the armature of which is energized via a power source 130′ based on a wireless signal received from a smart device (not shown) by the electronics module, referred to as PCBA 180′. A wireless radio in a microcontroller (MCU) mounted on PCBA 180′ is capable of acting as a transceiver, implementing protocols associated with any of the NFC, WIFI, 3G/4G/5G, GSM, Bluetooth and ZigBee standards, as well as for other known or developing wireless communication protocols, among various other communications standards. Furthermore, the MCU in PCBA 180′ may be used to wirelessly transmit status notifications to the smart device.
The AC motor 150′ is thus electrically connected to a PCBA 180′ and configured to power a gearbox 154′ (reduction gears with cam shaft) which rotates a horizontal lifting rod 155′ that is fixedly connected to spaced plates 156. The plates 156 in turn are connected to the pivotable foot 170′.
The plates 156 move with clockwise or counterclockwise rotation of the rod 155′ (dependent on rotary motion direction of AC motor 150′) to either raise foot 170′ from (or lower it to) the floor surface 107 so that pad 173 comes into frictional contact therewith. Somewhat similar to Applicant's DC-powered embodiment in the '746 application, upon the MCU in PCBA 180′ receiving a wireless signal (e.g., locking command) from a smart device, the armature of AC motor 150 energizes to impart or rotary motion to gearing in gearbox 154′ so as to rotate lifting rod 155′ in a counterclockwise direction. This lowers foot 170′ toward the floor surface 107, as described previously. The floor 107 exerts a counterforce which causes apparatus 100′ to act as a wedge between the door 105 and floor 107, effectively securing door 105 in place. Alternatively, apparatus 100′ may be employed to lock open door 105.
Conversely, upon the microcontroller in PCBA 180′ receiving a different wireless control signal (e.g., unlocking command) from smart device 140, the armature of AC motor 150 energizes to impart or rotary motion to gearing in gearbox 154′ so as to rotate lifting rod 155′ in a clockwise direction. This raises foot 170 away from the floor surface 107.
Power to the electrical components therein from the power source 130′ is provided by a manual on/off switch 125 on housing 110′. With switch 125 on, the power source 130′, such as an AC battery pack of alkaline or rechargeable cells 132, powers each of the AC motor 150′, PCBA 180′ and lamps 121′, 122′. Alternatively, AC wall power may be used in a wired configuration via a suitable adapter. Lamp 121′ indicates a locked (lamp 121′ green illuminated) or unlocked (lamp 121′ red illuminated) state. There is also lamp 122′ which indicates a battery fully charged (lamp 122′ green illuminated) or battery power low (lamp 122′ red illuminated) state.
An example embodiment of the present invention is directed to a removable, remotely-controlled door locking apparatus. The apparatus includes a rear plate for attachment against a surface of a door, a removable cover for enclosing components on the rear plate, and a telescoping arm assembly connected at one end to the rear plate and extendible upward so that a second end of the assembly attaches to a door knob of the door. The apparatus further includes a DC-powered linear actuator enclosed within the removable cover and connected to the rear plate, at least one electronics module attached to the rear plate and configured to communicate wirelessly, and a foot attached to a lower end of the DC-powered linear actuator, the foot configured under actuator control to be extended in a lock state against a floor surface to secure the door or retracted in an unlock state, based on a wireless signal received from a remote smart device to control the DC-powered linear actuator. The apparatus further includes a pressure sensor attached to the rear plate for, upon receiving a control signal based on a user of the remote smart device placing the remotely-controlled door locking apparatus in a lock state with a wireless command signal transmitted to the at least one electronics module, sensing a movement condition of the door only from its locked state such that the at least one electronics module generates an alarm signal locally at the door, and issuing a wireless alert message that is transmitted for display on the remote smart device of the user.
Another example embodiment is directed to a removable, remotely-controlled door locking apparatus which includes a rear plate having a plurality of electronic and mechanical components fixed thereon, a cover removably attached to the rear plate to enclose the plurality of electronic and mechanical components, and a DC-powered linear actuator enclosed within the cover and connected to the rear plate, the DC-powered linear actuator including a piston rod terminating in a foot, the DC-powered linear actuator either extending or retracting the piston rod and foot in response to a wireless signal transmitted from a handheld smart device to the apparatus. The apparatus further includes a telescoping arm assembly connected at a lower end to the rear plate and the DC-powered linear actuator, and extendible upward so that an upper end of the assembly attaches to a door knob of the door so as to facilitate stabilizing the apparatus with the rear plate flush against a door surface. The telescoping arm assembly further including a spring-biased hook, the spring-biased hook attached at its lower end to the upper end of the telescoping arm assembly via a single pin, such that the spring-biased hook is rotatable by a user in a direction opposite to a direction of spring pressure applied thereto so as to latch with spring force to the door knob, and a spring loaded, door bottom holding lip attached to the rear plate that engages an underside of the door to assist, in conjunction with the telescoping arm assembly, securing the rear plate against the door surface.

The apparatus includes a rear plate adapted to be removably secured against the door surface, a removable cover attached to the rear plate, and a control board attached to the rear plate for communicating wirelessly with a remote smart device and configured to send control signals to other electronic devices on the rear plate. The apparatus also includes an actuation control board which, based on a control signal wirelessly received via the control board from the remote smart device, sends a motor control signal to a DC-powered linear actuator so as to either extend a foot attached to a lower end of a piston of the actuator to seat the foot against a floor surface, or retract the piston and foot to disengage the floor surface. The control board further includes an undervoltage circuit that, upon sensing a low voltage condition, sends a control signal via the actuation control board to de-energize the actuator and retract the piston with foot from the floor surface.

Hereafter, the example embodiment is directed to a removable, remotely-controlled door locking apparatus 200. Referring now to
One or more electronics modules, namely a control board 280, an actuator control board 283, and a pressure sensor 285 are affixed on rear plate 213. Control board 280, which is the brain of the electronics modules, includes transceiver circuitry that enables wireless short-range RF communications with a remote smart device 240 (see
The actuator 250 includes a movable piston 254 which terminates at a lower end in a foot 270, which is attached to the piston 254 via a lock screw 271 and the like. A fixed upper piston casing 252 protrudes from the top of actuator 250 and is captured by a pin 261 so as to be secured to upper bracket 260 which supports the upper end of actuator 250 on rear plate 213. A lower bracket 255 connected to rear plate 213 supports the lower end of actuator 250. The piston 254 with foot 270 is configured under actuator 250 control to be extended in a lock state against a floor surface to secure the door or retracted in an unlock state, based on a wireless signal received from by control board 280 from the remote smart device 240 to control the actuator 250. This is described in further detail below.
Cover 210 is attached to rear plate 213 at cutout 214, which includes ball detents (not shown) which are captured in apertures within flanges 264 attached to rear plate 213. This permits cover 210 to be rotated up and down for internal access. The cutout 214 also provides clearance for a lower arm end cap 262 of a telescoping arm assembly 290, explained in further detail hereafter. Cover 210 may be constructed primarily from lightweight moldable plastic materials such as moldable plastic, e.g., as a single or multiple parts formed by an injection molding process using a high impact plastic such as Acrylonitrile Butadiene Styrene (ABS). ABS is an easily machined, tough, low cost rigid thermoplastic material with high impact strength, and may be a desirable material for turning, drilling, milling, sawing, die-cutting, shearing, etc. Virgin ABS may be mixed with a plastic regrind of ABS or another lightweight, durable plastic material. ABS is merely an example material, equivalent materials may include various thermoplastic and thermoset materials, such as talc-filled polypropylene, high strength polycarbonates such as GE Lexan®, or blended plastics.
There are many known injection molding machines for forming plastic injection molds, other plastic molding processes such as vacuum forming may be used. Alternatively, cover 210 may be formed using a metal casting process such as sand casting, die casting, or investment casting, for example.
The electronic modules of apparatus 200 may best be shown in
In one example, each of the control board 280 and actuation control board 283 may be embodied as a microcontroller (MCU)-on-chip, with control board 280 being capable of wireless short-range RF communications with a smart device 240 using BLUETOOTH protocols. As is well known, a BLUETOOTH device works by using short-range RF waves (two devices communicating typically up to about 30 feet apart) instead of wires or cables to connect with a smart device.
In one example, a commercially-available BLUETOOTH-capable module or chip usable for control board 280 may be an ARDUINO UNO REV3 Microcontroller. In another example, control board 280 may be embodied as a 2.4-GHz BLUETOOTH, low energy System-on-Chip by TEXAS INSTRUMENTS®, part numbers CC2540F128 or CC2540F256, configured for both ANDROID® and IOS® communications operations, as is known.
In another example, wireless fidelity (Wi-Fi) communications may be established between control board 280 and smart device 240 via various standard Wi-Fi protocols, with both being connected to a network. This configuration would require a Wi-Fi capable controller. Current Wi-Fi systems support a peak physical-layer data rate of 54 Mbps and typically provide indoor coverage over a distance of about 100 feet. Wi-Fi is based on the IEEE 802.11 family of standards (e.g., 802.11a for wireless Local Area Networks (LANs) with data transfer rates up to 54 Mbps in the 5-GHz band employing an orthogonal frequency division multiplexing (OFDM) encoding scheme as opposed to either the frequency-hopping spread spectrum (FHSS) or direct-sequence spread spectrum (DSSS); 802.11b, for wireless LANs with rates up to 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps depending on strength of signal) in the 2.4-GHz band using only DSSS; and 802.11g for wireless LANs with rates 20+ Mbps in the 2.4-GHz band). Accordingly, in a specific Wi-Fi configuration, control board 280 may be embodied as, in one example, a user-dedicated MCU Power Wi-Fi battery-operated chip, such as TEXAS INSTRUMENTS' CC3200 wireless MCU module.
In an example, a commercially-available actuator board 283 for use in apparatus 200 may be a POLOLU TReX Dual Motor Controller, part number DMC01. In an example, a commercially-available pressure sensor 285 may be a DIGIKEY (Reseller), 223-1528-ND, FX1901-0001-0025-L Sensor Tense Load Cell. Optionally, an audible alarm sensor (actuating upon the movement sensed by pressure sensor 285) may also be provided in apparatus 200, although not shown for purposes of brevity. A commercially available part for the audible sensor may be a DIGIKEY (Reseller) 445-5229-1-ND, PS1240P02CT3 audio piezo transducer.
As is well known in the art, electro-mechanical linear actuators convert rotary motion of a DC motor (such as a permanent magnet, stepped or brushless DC motor) into linear displacement. The electric motor is mechanically connected to rotate a lead screw, such as a ball-bearing lead screw for example. The lead screw has a continuous helical thread machined on its circumference running along the length (similar to the thread on a bolt). Threaded onto the lead screw is a lead nut or ball nut with corresponding helical threads.
A commercial example for the DC-powered linear actuator 250 may be an ECO-WORTHY 12V 2-Inch Stroke Linear Actuator. In actuator 250 operation (in general), current in the armature of the DC motor (applied based on a motor control signal from the actuator board 283) causes rotary motion of its motor. As the lead screw is rotated by the DC motor, the nut will be driven along the threads. The direction of motion of the nut depends on the direction of rotation of the lead screw. By connecting an upper end of the movable piston 254 to the nut, the motion of the lead screw is converted into a usable linear displacement, e.g. the piston 254 with foot 270 attached thereto either is retracted as the lead screw rotates in a first direction based on motor rotation (i.e., with apparatus 200 in the unlock state), or the piston 254 with foot 270 moves downward with the nut to the lock state as the lead screw rotates in a second opposite direction under DC motor control. Linear actuators are often supplied with limit switches, such as electro-mechanical, magnetic proximity and rotary cam. These limit switches are designed to control the length of the stroke of the piston 254 for a particular application.
Although the example embodiments are not so limited, typical specifications for these linear actuators include any of a DC Mini permanent magnet motor, brushless DC motor, or stepper motor configured to handle a max load of at least 100 N, in an example range between about 100 to 2500 N, configured to generate a turning speed from about 5 mm/s to 80 mm/s, and achieving a stroke of about between 20-1100 mm with built-in limit switches.
The power supply for apparatus 200 to power the electronics and DC motor of actuator 250 may be in one example a battery pack 230 comprising one or more alkaline batteries or rechargeable batteries, which seats into a battery compartment 232 affixed to rear plate 213. A well-known push-push button 234 (accessible through a cutout 212 in cover 210) may be used to locking engage and disengage pack 230 into compartment 232. In a further alternative, the power supply could be solar-powered, where solar cells can be charged by ambient light or by a combination of a rechargeable battery with solar cells to charge the battery pack 230. Alternatively, battery pack 230 may be charged remotely via an external charger with wall power, as shown in
In an example, it is desirable that apparatus 200 be removeably attachable against the surface of door 250 with minimal, if any, marring of the door 205. Although rear plate 213 is provided with corner holes 218 to receive fasteners for permanent affixation of rear plate 213 to door, the Applicant has devised a much less intrusive attachment means for apparatus 200. Namely, this may be accomplished by employing a combination of a telescoping arm assembly 290 and a spring loaded, door bottom holding lip 215 that engages an underside of the door 205 to assist in securing the apparatus 200 thereto.
For the spring loaded, door bottom holding lip 215, reference is made to
Referring now to
Assembly 290 also includes attachment means 295 affixed between part of the arm assembly 290 (lower arm 291) and a surface of the door 205. In this example, these are illustrated as a plurality of suction cups 295. This connection provides additional stability for apparatus 200 against the surface of door 205, and with the bottom lip 215 offers a non-mark means of attaching apparatus to door 205. In an alternative, suction cups 295 could be substituted with hook and loop material fasteners, and/or a light adhesive to secure telescoping arm assembly 290 of the apparatus 200 to a surface of the door 205.
Turning to
In general, once paired, wireless communications between a user of the smart device 240 to control apparatus 200 can be understood as follows. With the system mode “Off”, no current is applied by battery pack 230 to the actuator 250 or the associated electronics (control PCB 280, actuation control board 283). Upon selection or tapping the “LOCK” icon 243, the following operations occur: (i) a wireless signal is sent from the smart phone 240 to the control board 280; (ii) this is communicated by control board 280 to actuator board 283, which in turn (iii) sends a motor control signal to the armature in the motor of actuator 250 to cause the motor to rotate in one direction, which (iv) causes the piston 254 with foot 270 to travel downward to the floor surface to maintain door 205 secured. In this “lock state”, any pressure or force moment exerted against the door 205 from the outside thereof will be sensed by pressure sensor 285, which in turn will cause an alert signal to be transmitted wirelessly from control board 280 to the smart device 240 for alert signal display thereon. An alarm indication will flash on display 241 to alert the user, may be accompanied by sound, and may be recorded by time, date and event on the events page (as shown by action icon 247). Conversely, upon selection or tapping the “UNLOCK” icon 244 to change system mode, the reverse operations occur.
Cyber hacking remains a concern; hence communication via BLUETOOTH protocol should be able to limit the possibility of the application becoming compromised. The application on smart device 240 only works within a certain distance of the apparatus 200, in one example a range of about between 5 to 30 m, in another specific example about 30 feet or less. If a hacker desired access, he/she would need to be already in the user's home specifically looking for that application on the user's smart device 240. This is not likely, and by this time the homeowner would be off to safety. Additionally, Bluetooth is more likely to be turned off on the user's smart device 240 rather than Wi-Fi in order to conserve battery life. Once off, Bluetooth hacking is not possible.
The smart device 240 has been described as being embodied as any of smartphones, phablets and tablets, smartwatches, smart bands and smart key chains, a smartphone example having being shown in

The foregoing discussion of the invention has been presented for purposes of illustration and description. The foregoing is not intended to limit the invention to the form or forms disclosed herein. In the foregoing Detailed Description for example, various features of the invention are grouped together in one or more embodiments, configurations, or aspects for the purpose of streamlining the disclosure. The features of the embodiments, configurations, or aspects of the invention may be combined in alternate embodiments, configurations, or aspects other than those discussed above. This method of disclosure is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment, configuration, or aspect. Thus, the following claims are hereby incorporated into this Detailed Description, with each claim standing on its own as a separate preferred embodiment of the invention.
Moreover, though the description of the invention has included description of one or more embodiments, configurations, or aspects and certain variations and modifications, other variations, combinations, and modifications are within the scope of the invention, e.g., as may be within the skill and knowledge of those in the art, after understanding the present disclosure. It is intended to obtain rights which include alternative embodiments, configurations, or aspects to the extent permitted, including alternate, interchangeable and/or equivalent structures to those claimed, whether or not such alternate, interchangeable and/or equivalent structures disclosed herein, and without intending to publicly dedicate any patentable subject matter.
The present application claims the benefit under 35 U.S.C. § 120 and is a continuation-in-part of U.S. patent application Ser. No. 14/876,746 to Finley, et al.
