Abstract
A system, method and device for monitoring fluid dispensing are described. The method includes coupling a plurality of sensors to a valve of a fluid dispensing assembly, wherein the valve is configured to operate in either a first state or a second state to control fluid flow from the inlet to the outlet. A change of a state of the valve is detected from the first state to the second state from the second state back to the first state. The detected data from the detected sequence of triggering events, a time duration and a predetermined flow rate may be transmitted through a wireless transceiver, to one or both of an external user device and a remote central monitoring unit for a determination of a volume V of fluid being dispensed.
Description
TECHNICAL FIELD

This disclosure relates to monitoring content dispensing and inventory tracking, more specifically to the dispensed inventory which are in fluid state.


BACKGROUND

Inventory tracking in a business can be quite tedious, often resulting in personnel spending a significant amount of time on a regular basis to record the amount, age, expiration, location, usage patterns, shrinkage, sales or sale pace of products. Tracking inventory is especially challenging in multi-tier supply chains where manufacturer or suppliers may need most up to date information on product movement at many commercial, retail or end user locations they may have limited or no access to. The need for this information may be driven by regulatory requirements, product planning, sales and marketing data needs. Some examples of products requiring inventory monitoring and tracking include: beer in kegs, alcoholic beverages, pesticides in sprayers, gasoline or natural gas in tanks, and pills in bottles. Take an example of beer dispensing, when one considers that a half barrel/full keg of beer is around 16 U.S. gallons (60.6 liters), one realizes that there are only about 128 one pint (0.5 liters) servings of beer in a keg. A waste of, or failure to log, 13 pint servings of keg product from a keg results in a 10% error in tracking remaining keg product via sales recordings.

DETAILED DESCRIPTION

The disclosure describes a monitoring and tracking device that provides cost-effective way of tracking product inventory that is accurate, efficient, easy to implement, provides timely data, can operate remotely, requires minimal or no end user interaction, consumes minimal power and having a small form factor. The disclosure describes an exemplary method of analyzing dispensing or consumption of product inventory, and/or consumption trends related thereto, that is accurate, efficient, and easy to implement.


The monitoring and tracking device to be described find applications including: any valve or dispenser that connects to a container or to a supply line, which detects a product dispensing or shut off mechanism caused by a mechanical shock, or in combination with a change in magnetic field. The monitoring and tracking device may be installed in infrastructure of various dispenser types already existing and the monitoring and tracking device may retrofit without interfering with existing dispensing mechanisms in form, fit or function. The monitoring and tracking device may have low power consumption with long service life using a battery small enough to achieve monitoring the sensors and to broadcast data upon accumulating certain number of successful events.


In general, according to the present invention, data relating to the state, the use and certain contextual parameters of an inventory may be collected and transmitted, either subsequently after a duration or in real-time over an electronic network such as the Internet, to a remote site from the monitoring and tracking device for storage, later manipulation and presentation to a recipient. One or more sensors may be integrated within the monitoring and tracking device to generate signals in response to detecting dispensing events associated with a change of states in a valve of a fluid dispensing system. The generated signals may include signals generated from one or a combination of: a Mems sensor, accelerometer, gyroscope, magnetometer, biometric sensor, microphone for speech recognition, light sensor, touch sensor, motion sensor, humidity sensor, pressure sensor, proximity sensors, RFID transponder, geolocation (GPS) sensor et al.


In addition, sensor device may generate other data indicative of various conditions of a dispenser such as the location, movement information, attachment or detachment of the device to the dispenser, open or close of the dispenser, in use or our of use state of the dispenser, temperature of the dispenser or near the dispenser, orientation, timestamps of conditions or events, inventory levels, raw motion data, data derived from motion data or external conditions to the device, events derived from sensed external conditions, threading or unthreading of a dispenser handle. Sensor device generates data indicative of various conditions of the device such as the device ID, battery voltage, time since last transmission, GPS location, motion, location based on cell towers, timestamp, attachment to a dispenser, detachment from a dispenser, in-use state, out-of-use state, temperature or antenna signal strength.


In certain cases, the data indicative of the various conditions is the signal or signals themselves generated by the one or more sensors and in certain other cases the data is calculated by the microprocessor based on the signal or signals generated by the one or more sensors. Methods for generating data indicative of various conditions and sensors to be used therefor include: analyzing dispensing patterns, attachment and detachment patterns, temperature changes, or other motions of the device in order to generate data indicative of the dispenser location, dispenser performance, volume dispensed, volume remaining, dispenser maintenance, product age, product temperature, product quality, product pressure or product flow rate.


Additional data indicative of the dispenser in a draft beer system may include: the time a keg is placed in or removed from the cooler, the time the keg is tapped or untapped, the actuation of a FOB (Foam on beer device) or the resetting of a FOB.


The sensor may associate a probability or confidence level to the data, condition or event communicated. The sensor may store a library of conditions, criteria and/or event types for assessing sensed conditions. Said library may be programmed once or updated when the sensor communicates or as the sensor operates. Algorithms or decision criteria may be modified over time by data recorded by the sensors, data received from the cloud, data received from other sensors directly or via the cloud, by input directly from a user, by input from a user via the cloud or other.


The generated data from the sensor device may be communicated wirelessly in one or more schemes, including: in real-time, periodically, delayed, upon reaching a predetermined cumulative triggering events or a predetermined cumulative flow volume, in burst broadcast mode and encrypted.



FIG. 1 illustrates a fluid dispensing assembly 100 with an integrated fluid monitoring and tracking device handle 105. The integrated fluid monitoring and tracking device handle 105 may include an embedded fluid monitoring and tracking device 102 (also known as “tracking device”) inserted within a hollow portion of the handle 105. The embedded tracking device 102 may not obstruct an actuating movement 150 of the handle 105 when dispensing fluid 130. In an example shown in FIG. 1, the fluid dispensing assembly 100 may be a beer tap apparatus attached to a wall or attached to a beer dispensing tank 120.


The fluid dispensing assembly 100 may include a dispenser body 104, a valve 106, a handle 105, an inlet 108, and an outlet 110. The inlet 108 of the dispenser body 104 is configured to be connected either to a fluid container or to a conduit that transports fluid, and the valve 106 is disposed between the inlet 108 and the outlet 110, wherein the valve is configured to operate in either a first state (open) or a second state (shut) to control fluid (such as pressurized fluid) flow from the inlet 108 to the outlet 110.


The handle 105 is a movable structure of the fluid dispensing assembly 100. In other embodiments, the movable structure may be a mechanical switch, a mechanical trigger, a lever, and a solenoid relay, and wherein the tracking device is either integrated within or externally attached to the fluid dispensing assembly (see FIGS. 10-14).


The Actuation move 150 of the handle 105 which opens valve 106 may be detected as a triggering event, which an acceleration motion is detected by an accelerometer sensor. Alternatively, the actuation movement of the handle 105 may also be detected through an angular tilt which may be detected by a gyroscope sensor or detected by a change in magnetic field through a magnetometer sensor. In another example, the triggering event may be detected as attachment or detachment of the fluid dispensing assembly 100 or the tracking device 102.


As illustrated in FIG. 1, handle 105 and tracking device 102 may be in a first state, that is, the valve 106 is closed and no fluid is dispensed. The handle 105 and the tracking device 102 may be in a second state, where the valve 106 is opened and fluid 130 is dispensed. As described below, the tracking device 102 may be configured to sense a start and a termination of a fluid dispensing event of the valve 106 through detecting a state change of a motion sensor (such as accelerometer) from a first state (valve closed—no fluid dispensed) to a second state (valve open—fluid is dispensed) and vice versa. The motion sensor detects an acceleration when the handle 105 is being set into motion from a rest position to another position. Alternately, the fluid dispensing event may be detected based on a combination of detecting exceeding a threshold of acceleration and exceeding a time duration of holding the handle 105 after being set into an initial motion to begin tracking a volume V of fluid 130 dispensed over time duration ΔT according to a calibrated or a predetermined constant fluid flow rate Q. The constant flow rate Q may be maintained by regulating a substantially constant internal pressure in the container 120 (such as the beer keg). The volume of fluid dispensed may be calculated by the equation V=Q*ΔT.



FIG. 2 illustrates an alternate embodiment of a fluid dispensing assembly 200 installed with an external fluid monitoring and tracking device 202 (i.e., tracking device). The tracking device 202 may be housed in a housing 211 and externally attached to a handle 205 through an attachment element 212. In this shown example, the housing 211 is sufficiently small without interfering an actuation movement 250 of the handle 205 for opening and closing of a valve 206. In an example, the housing 211 may be constructed from a heat conductive metal or alloy (e.g., aluminum) to allow device components housed inside the housing 211 to measure an ambient air temperature or the temperature of the fluid dispensing assembly where it contacts the housing. The housing 211 may alternately be constructed from any material, including for example a polymer, a metal, or an alloy.


In this shown example, the attachment element 212 may be an extension of a surface 214 of the housing 211. The housing 211 may be operatively connected to at least one of a product inventory storage system and a delivery system via the attachment element 212, wherein the attachment element 212 may be attached to the handle 205 by means of any one of: an opening, a hook and loop fastener, a threaded screw, a threaded recess, a snap fitting, a magnet, a hook, a ring, an adhesive, a clamp, a string, a wire, and a rope.


In addition, the tracking device 202 may include a plurality of sensors to detect a sequence of triggering events to determine a state change of the valve 206. The sensors may perform one or more of: (1) using an accelerometer to detect a sudden change of a position of a movable structure of the fluid dispensing assembly, a sudden shock force of a movable structure of the fluid dispensing assembly, a sudden change in motion of a movable structure of the fluid dispensing assembly; (2) using a magnetometer to detect a change or disruption of existing magnetic field to the movable structure of the fluid dispensing assembly; (3) using a gyroscope to detect a tilt or a change of radial angle of the movable structure of the fluid dispensing assembly; (4) using a piezoelectric pressure sensor to detect an applied pressure formed by the movable structure of the fluid dispensing assembly; (5) using a thermocouple to detect temperature change of the housing which is in contact with the fluid dispensing assembly as a result of operating the movable structure of the fluid dispensing assembly; and (6) using a photodetector to detect a disruption to an intensity of an optical beam caused by the movable structure of the fluid dispensing assembly. There may be other sensors used in the triggering event, which not limited to the scope of the disclosure.



FIG. 3A illustrates a perspective view of a stand-alone fluid monitoring and tracking device 302. FIG. 3B illustrates a perspective view of a fluid monitoring and tracking device 302 installed on a handle 305 of a fluid dispensing assembly 300. As shown in FIG. 3A, the attachment element 312 may be a flange with a through hole opening 313 which may be a structural extension from the housing 311. As shown in FIG. 3B, the tracking device 302 is externally attached to the handle 305 through coaxially inserting and threading a valve portion 306 of the fluid dispensing assembly 300 through the hole opening 313 into the handle 305. Housing 311 may house a circuit board having a plurality of device components to monitor and track fluid dispensing, as further described in FIG. 6. In operation, the tracking device 302 may sense an actuation motion 350 of the handle 305 to trigger a change of state of a valve 306 to start dispensing fluid 330.



FIG. 4 illustrates individual fluid monitoring and tracking devices 402 installed on respective handles 405 of individual fluid dispensing assembly 400, such as a beer tap apparatus. In an alternate embodiment, the tracking device 402 may utilize other sensors other than a motion detector sensor (e.g. accelerometer). For example, the tracking device 402 may include a touch sensor which detects a change of capacitance when touched or a near field proximity sensor which operates inductively by reading a code from a RFID transponder 425 in order to control opening and closing of individual valve 406 in the individual fluid dispensing assembly 400. For example, the valve 406 may be controlled to open or shut by a touch of a hand on the handle 405 or a touch on the housing 411 of the tracking device 402, or through placing a RFID transponder 425 proximal to the tracking device 402 to unlock the valve 406 to dispense fluid from the container.


To add assurance to the detecting of the sequence of triggering events to open the valve to dispense fluid, an accessory device 491 may be coupled to the fluid dispensing assembly 400 and to the tracking device 402 to perform user verification prior to receiving the permission to dispense fluid. The accessory device may be a smart device having a display, a touch screen, a scanner and a near-field transponder to perform one or more of the verification methods as follows: (1) receiving user's biometric data on a biometric input device through detecting one of: finger prints, e-signature, voice signature; (2) scan in user's one-dimensional or two-dimensional (QR) barcode; (3) read a code from a user's RFID tag; and (4) receive on a touch screen, one or both of user's finger gesture and a user's password.



FIG. 5 illustrates a system diagram of a fluid monitoring and tracking device 500 communicating with a plurality of network devices 591-594. Any of the aforementioned tracking devices (102, 202, 302, 402) may include device components 531-537 housed within respective housings 211-411. The device components may include one or more sensor 531, a wireless transceiver 532 including an antenna 537, a memory 533 which stores executable program code, sensor data and a database 534, a power source 535 and a processor 536 operatively connected to the wireless transceiver 532. The power source 535 may be a battery which supplies direct current (dc) to power the one or more sensor 531, wireless communication device 532, and memory 533. In an embodiment, the one or more sensor 531 may be at least one or a combination of: an accelerometer for sensing an acceleration or an abrupt motion, a magnetometer for sensing a change in magnetic field or detection of a non-uniform magnetic field, a gyroscope for sensing a relative change in radial angles, a motion sensor for sensing movement, a touch sensor which senses a change of capacitance due to touch or a near field proximity sensor which may communicate inductively to read address code from a RFID tag. A combination of sensors 631 may be configured to perform both monitoring function of fluid flow and control function to open and close the valve 406 of the individual fluid dispensing assembly 400. A timer (built into the processor 536) may be used to monitor a duration of fluid flow in order to provide a reading of how much inventory has been dispensed and to track remaining inventory in a container.


As shown in FIG.5, an accessory device 591 may be one of the network devices which may be communicatively coupled to the fluid dispensing assembly 400 and to the tracking device 402 to perform user verification prior to receiving the permission to dispense fluid.


The wireless communication device 532 may be in a standby state (i.e., low power or sleep mode) or in an operating state. The memory 533 may include a nonvolatile semiconductor memory. In an example, upon sensor 531 sensing a trigger condition (such as an actuation of handle 306) which indicates opening of the valve 306, sensor 531 may store sensed condition in the memory 533 and send a command to the wireless communication device 532 to transmit the recorded sensed condition. Wireless communication device 532 may, upon receiving the command from the sensor 531, transition from a standby state to an operating state to transmit the sensed condition, then transition back to the standby state. The standby state may consume just sufficient power from power source 535 for wireless communication device to receive and interpret the command from the sensor 531, but may consume an insufficient quantity of power from power source 535 than is needed for wireless communication device 532 to communicate wirelessly. The operating state may consume a sufficient quantity of power from power source 535 for wireless communication device 532 to communicate wirelessly.


When sensor 531 is “on” during the standby state of wireless communication device 532, sensor 531 may draw less power than wireless communication device 532 in wireless communication device 532′s operating state. In this manner, power may be conserved to extend the life of power source 535.


In one embodiment, sensor 531 may be in an interrupt state to draw minimal power from power source 535. Sensor 531 may draw less power in operating state than wireless communication device 532 in operating state. In this manner, power in power source 535 may be conserved, thus increasing the life of power source 535.


In other embodiment, the wireless transceiver 532 may wake up from a low power sleep mode upon detecting one or both of: a sequence of triggering events and the verification of user's identity. Subsequent to the waking up, the wireless transceiver delays transmission to one or both of the external user device and the remote central monitoring unit until a buffer of the tracking device has reached a predetermined storage level as a result of successive counts of detection of data from the detected sequence of triggering events, and the time duration ΔT.


Wireless communication device 532 may communicate over a range of radio frequency spectrum. Wireless communication device 532 may communicate via any known wireless communication method. Wireless communication device 532 may include at least one of: a transmitter, a receiver, a transceiver, and an antenna 537. The wireless communication device 532 may transmit the recorded sensed condition or sensed data to a wireless network 675. The network 675 may be one of: an Internet through a gateway device, a cellular network through a radio tower or a cellular tower, and a local network through a remote device as shown in FIG. 6. The network may be a wireless network.


In addition, sensor 531 may further include at least one of: a liquid quantity sensor to sense a quantity of liquid passing through a system, a liquid flow sensor to sense the flow of a liquid through a system, a motion sensor to sense motion of tracking device 102 to 402, an orientation sensor to sense the orientation of tracking device 102 to 402, an accelerometer (or other binary position sensor) to sense movement and/or orientation of tracking device 102, 202, 302, an accelerometer to sense shock or vibration of tracking device 102 to 402, a gyroscope to sense movement and/or orientation of tracking device 102 to 402, a global positioning system sensor to sense movement and/or orientation of tracking device 102, 202, 302, a magnetometer to sense movement and/or orientation of tracking device 102, 202, 302 relative to a magnetic field, a force sensor to sense force applied to tracking device 102 to 402, a pressure sensor to sense pressure of a fluid passing through a system and/or pressure applied to tracking device 102, 202, 302, a light sensor to sense movement of tracking device 102 to 402, a radio frequency identification (RFID) sensor to sense proximity of a user and/or identify a particular user, a temperature sensor to sense the ambient temperature in the area of tracking device 102 to 402 and/or the temperature of a fluid passing through a system, a microphone to sense fluid mass and/or fluid flow, and a camera to visually recognize the position of handle 105, 205.


Sensor 631 may be calibrated for each application of tracking device 102 to 402. Sensor 631 may, for example, sense the tipping of handle 105 and thus opening of valve 106, 406. A user may install sensor in a fluid dispensing assembly 100 to 400, open valve 106, 406, and dispense a known quantity of fluid into a container of a known volume. Sensor 631 may sense the time between which valve 106 is opened and closed and thus the amount of time during which valve 106, 406 is opened. A user may calculate the volume of fluid dispensed during that amount of time, divide that volume by the amount of time recorded, and obtain a volume flow rate. This volume flow rate may be input into tracking device 102 to 402 via an input element described herein, such that tracking device 102 to 402 and sensor 631 is calibrated to the specific volume flow rate associated with that fluid dispensing assembly 100 to 400. Alternatively, a user may simply input the volume of fluid dispensed during the sensed time interval, and tracking device 102, 202, 302 may perform the necessary calculation to determine the volume flow rate associated with that fluid dispensing assembly 100 to 400.


Fluid dispensing assembly 100 to 400 may experience inconsistency in the volume flow rate of dispensing of a product over time. For example, volume flow rate may change as product within the product storage container (such as a beer keg) is diminished. As a result, tracking device 102 to 402 and/or remote device 775 and/or the central monitoring unit 1001 may apply a known curve to estimation of volume of product dispensed to account for this change, and may adjust recorded dispensed product volumes accordingly.


Fluid dispensing assembly 100 to 400 may experience inconsistency in the volume flow rate of dispensing of a product due to inconsistent opening of valve 106, 406. That is, where a user, such as a bartender, does not open valve 106, 406 completely, fluid may not be dispensed at the calibrated volume flow rate. Sensor 631 may sense how far valve 106, 406 is opened, for example by how far handle 105, 405 is actuated during product dispensing. Tracking device 102 to 402 and/or remote device 775 may sense a failure to open valve 106, 406 completely, and may at least one of: alert the user (e.g., bartender) to open valve 106, 406 completely, and adjust the calculated product dispensed volume to account for failure to open valve 106, 406 completely.


Tracking device 102 to 402 may alternately be integrated with a wireless temperature sensor located in a product storage area (e.g., a cooler) and alert a user if storage temperatures are not within a desired threshold. Tracking device 102 to 402 may integrate with a wireless CO2 regulator sensor operatively connected to a CO2 supply connected to fluid dispensing assembly 100 to 400, and alert a user if CO2 pressures/supplies are not within a desired threshold. Tracking device 102 to 402 may integrate with a wireless gas regulator sensor operatively connected to a gas supply connected to fluid dispensing assembly 100 to 400, and alert a user if gas pressures/supplies are not within a desired threshold.


The gas may include any gas commonly used to pressurize a fluid to be dispensed, including for example, CO2, N2, O2, atmospheric air, and the like. The gas may include any gas commonly used to pressurize a fluid to be dispensed, including for example, CO2, N2, O2, atmospheric air, and the like. Tracking device 102 to 402 may be integrated with a wireless sensor operatively connected to a keg or keg coupler connected to fluid dispensing assembly 100, 400, and alert a user if a keg is changed. Tracking device 102 to 402 may be integrated with a wireless sensor operatively connected to a lid, cap, handle or other component connected to fluid storage assembly and alert a user if the storage assembly is opened or refilled. Tracking device 102 to 402 may be integrated with a sensor including at least one of: a temperature sensor configured to measure a temperature of a product in product storage, a temperature sensor configured to measure a temperature of a product in a product delivery system, a keg or keg coupler sensor configured to measure a status or condition of a keg, a lid, cap or handle sensor configured to measure the opening and closing or refilling of a storage container and a gas regulator sensor configured to measure a pressure of a gas supply operatively connected to the product delivery system. In this manner, tracking device 102 to 402 and/or remote device 775 and/or central monitoring unit 1001 may provide a user with a general “system health” analysis.
