Abstract

In an exemplary method of monitoring usage of an electronically operated dispenser, a dispensing mechanism is operated by an internal controller of the dispenser in response to user activation of an actuator of the dispenser in communication with the controller. In response to operation of the dispensing mechanism, dispenser data is written to an internal dispenser memory in wired communication with the controller, with the controller and the dispenser memory being electrically connected with and powered by a power source. The dispenser memory receives a wireless interrogation signal from an external reader and collects energy from the wireless interrogation signal. In response to receipt of the wireless interrogation signal, the dispenser memory wirelessly transmits the written dispenser data to the external reader, with the dispenser memory being powered by the collected energy.

Claims

1. A method for monitoring usage of an electronically operated dispenser, the method comprising:

operating a dispensing mechanism by a controller in response to activation of an actuator in communication with the controller;

wherein the dispenser includes a dual interface memory that includes a wired interface and a wireless interface;

wherein the dual interface memory is configured to receive power through the wired interface and to receive power through the wireless interface;

in response to operation of the dispensing mechanism, writing dispenser data to an internal dispenser dual interface memory in wired communication with the controller, with the controller and the dispenser dual interface memory being powered by a power source electrically connected with the controller and the dispenser memory;

receiving a wireless interrogation signal from an external reader and collecting energy from the wireless interrogation signal;

in response to receipt of the wireless interrogation signal, wirelessly transmitting the written dispenser data from the dispenser dual interface memory to the external reader, with the dispenser dual interface memory being powered by the collected energy.

2. The method of claim 1, wherein wirelessly receiving the wireless interrogation signal comprises wirelessly receiving an ultra high frequency (UHF) radio frequency identification (RFID) signal.

3. The method of claim 1, wherein wirelessly transmitting the written dispenser data comprises wirelessly transmitting an ultra high frequency (UHF) radio frequency identification (RFID) signal.

4. The method of any of claim 1, wherein operating the dispensing mechanism comprises dispensing a hand hygiene fluid.

5. The method of claim 1, wherein writing dispenser data to the internal dispenser memory comprises writing at least one of dispense count data and dispenser status data to the internal dispenser dual interface memory.

6. The method of claim 1, further comprising:

activating an activity monitor in response to user activity at a location in proximity with the activity monitor;

in response to activation of the activity monitor, writing user activity data to an internal monitor dual interface memory of the activity monitor, with the monitor dual interface memory being powered by a power source electrically connected with the activity monitor;

wirelessly receiving in the monitor dual interface memory a wireless interrogation signal from an external reader and collecting energy from the wireless interrogation signal;

in response to receipt of the wireless interrogation signal, wirelessly transmitting the written user activity data from the monitor dual interface memory to the external reader.

7. The method of claim 6, further comprising associating the written user activity data with the written dispenser data in the external reader.

8. The method of claim 6, further comprising wirelessly transmitting a wireless interrogation signal from the external reader to a radio frequency identification (RFID) badge of a user at a location proximate to one of the activity monitor and the dispenser, and receiving user identification data from the RFID badge at the external reader.

9. The method of claim 8, further comprising associating the received user identification data with the written user activity data in the external reader.

10. The method of claim 1, further comprising transmitting the written dispenser data from the external reader to a central computer system.

11. An electronically operated dispenser comprising:

a housing;

a dispensing mechanism electrically connected with a power source;

an actuator;

a controller electrically connected with the power source, the controller being in communication with the actuator and configured to operate the dispensing mechanism in response to user actuation of the actuator; and

a dispenser dual interface memory including a wired interface and a wireless interface;

wherein the wired interface supports wired communication, powered by the power source, between the dispenser dual interface memory and the controller, for writing dispenser data from the controller to the dispenser memory; and

wherein the wireless interface supports passive wireless communication between the dispenser dual interface memory and an external reader, for transmitting the written dispenser data from the dispenser dual interface memory to the external reader, with the dispenser data transmission being powered by energy collected from an external reader interrogation signal by the dispenser dual interface memory.

12. The dispenser of claim 11, further comprising a housing retaining the dispensing mechanism, the controller, and the dispenser dual interface memory.

13. The dispenser of claim 11, wherein the power source is disposed in the housing.

14. The dispenser of claim 11, wherein the wireless interface is configured to receive and or transmit ultra high frequency (UHF) radio frequency identification (RFID) signals.

15. The dispenser of claim 11, wherein the dispenser data comprises at least one of dispense count data and dispenser status data.

16. The dispenser of claim 11, wherein the actuator comprises at least one of an optical sensor, a motion sensor, a microphone, and a button actuated mechanism.

17. An electronically operated dispenser comprising:

a housing;

a dispensing mechanism located in the housing;

one or more batteries located in the housing for providing power to the dispenser components;

an actuator;

a controller electrically connected with the one or more batteries, the controller being in communication with the actuator and configured to operate the dispensing mechanism in response to a signal from the actuator; and

a dispenser dual interface memory including a wired interface and a wireless interface;

wherein the wired interface supports wired communication, powered by the one or more batteries, to the dispenser dual interface memory; and

wherein the wireless interface supports passive wireless communication between the dispenser dual interface memory and an external reader.

18. The dispenser of claim 17 further comprising a radio frequency identification device (“

RFD”

) powered by the one or more batteries.

19. The dispenser of claim 17 further comprising a spout configured to mount to a countertop.

20. The dispenser of claim 17 wherein the dispenser is a wall mounted dispenser.
