Abstract

A fluid management system includes an authentication device and a fluid dispensing meter, and the fluid dispensing meter includes a processor and a memory. The authentication device is configured to provide user-identification data to the processor. The processor is configured to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control a trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.

First claim

1 . A fluid dispensing meter comprising:
a trigger control mechanism mounted in a body of the fluid dispensing meter, the trigger control mechanism controllable between an activated state, where the fluid dispensing meter can dispense fluid, and a deactivated state, where the fluid dispensing meter is prevented from dispensing fluid; a data receiver mounted on the fluid dispensing meter, the data receiver configured to receive data from an external data source; and a control board disposed within the bezel housing, the control board comprising:
a processor; and
a memory encoded with instructions that, when executed by the processor, cause the processor to recall approved user identities from the memory, to compare the approved user identities to user-identification data received from an external data source, and to control the trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.

2 . The fluid dispensing meter of claim 1 , wherein the data receiver comprises:
an antenna configured to receive the user-identification data from the external data source and provide the user-identification data to the processor.

3 . The fluid dispensing meter of claim 2 , wherein the antenna is configured to receive the user-identification data from an authenticator via near field communications.

4 . The fluid dispensing meter of claim 1 , wherein the data receiver comprises:
an integrated optical scanner mounted on the fluid dispensing meter; and wherein the external data source is a visual pattern, and the integrated optical scanner is configured to scan the visual pattern to receive the user-identification data.

5 . The fluid dispensing meter of claim 4 , wherein a bezel housing is mounted on the body of the fluid dispensing meter and the bezel housing includes a scanner opening extending through the bezel housing, and wherein the integrated optical scanner is configured to receive the user-identification data through the scanner opening.

6 . The fluid dispensing meter of claim 1 , wherein the trigger control mechanism comprises:
a solenoid mounted on the body; and a trip rod extending from the solenoid to a trigger of the fluid dispensing meter; wherein the solenoid is configured to lock the trip rod in place within the meter body with the trigger control mechanism in the activated state, and the solenoid is configured to unlock the trip rod such that the trip rod is movable within the meter body with the trigger control mechanism in the deactivated state.

7 . A fluid management system comprising:
an external data source configured to generate a user-identification signal including user-identification data; a fluid dispensing meter comprising:
a trigger control mechanism mounted in a body of the fluid dispensing meter, the trigger control mechanism controllable between an activated state, where the fluid dispensing meter can dispense fluid, and a deactivated state, where the fluid dispensing meter is prevented from dispensing fluid;
a data receiver mounted on the fluid dispensing meter, the receiver configured to receive the user-identification data from the external data source;
a control board disposed on the fluid dispensing meter, the control board comprising:
a processor; and
a memory encoded with instructions that, when executed by the processor, cause the processor to recall approved user identities from the memory, to compare the approved user identities to the user-identification data received from the authenticator, and to control the trigger control mechanism between the activated state and the deactivated state based on the comparison of the user-identification data and the approved user identities.

8 . The fluid management system of claim 7 , wherein the processor is configured to place the trigger control mechanism in the activated state based on the user-identification data matching the approved user identities.

9 . The fluid management system of claim 7 , wherein:
the external data source comprises an authenticator; and the data receiver comprises an antenna configured to receive the user-identification data from the authenticator and to provide the user-authentication data to the control board.

10 . The fluid management system of claim 9 , wherein the authenticator comprises a near field communication (NFC) device.

11 . The fluid management system of claim 10 , wherein the authenticator is selected from a group consisting of an NFC access card, an NFC wristband, an NFC ring, and an NFC belt.

12 . The fluid management system of claim 9 , wherein the antenna is disposed within a bezel housing mounted on the body of the fluid dispensing meter.

13 . The fluid management system of claim 7 , and wherein:
the external data source comprises a visual pattern containing dispense-identification data; the data receiver comprises an integrated optical scanner mounted on the handheld fluid meter, the integrated optical scanner configured to scan the visual pattern to receive the dispense-identification data and to transmit the dispense-identification data to the processor; and the memory is encoded with further instructions that, when executed by the processor, cause the processor to recall authorized-dispense data from the memory, to compare the authorized-dispense data to the dispense-identification data, and to control the trigger control mechanism between the activated state and the deactivated state based on the comparison of the authorized-dispense data and the dispense-identification data.

14 . The fluid management system of claim 13 , wherein the dispense-identification data is work order-identification data configured to identify a work order.

15 . The fluid management system of claim 13 , wherein the dispense-identification data is user-identification data configured to identify a user.

16 . The fluid management system of claim 13 , wherein the fluid dispensing meter further comprises:
a scanner opening extending through a bezel housing mounted on the body of the fluid dispensing meter, wherein the integrated optical scanner is configured to scan the visual pattern and receive the dispense-identification data through the scanner opening.

17 . The fluid management system of claim 16 , wherein the visual pattern is selected from the group consisting of a bar code and a QR code.

18 . The fluid management system of claim 7 , further comprising:
a peripheral device configured to receive work order-identification data and communicate the work order-identification data to the processor, wherein the processor is configured to recall authorized-dispense data from the memory, to compare the authorized-dispense data to the work order-identification data, and to control the trigger control mechanism between the activated state and the deactivated state based on the comparison of the work-order identification data and the authorized-dispense data.

19 . The fluid management system of claim 18 , wherein the peripheral device is an external optical scanner configured to receive the desired work order information from a visual identifier.

20 . The fluid management system of claim 18 , wherein the peripheral device is a system controller.

21 . A method of authorizing a fluid dispense, the method comprising:
receiving user-identification data at a processor of a fluid dispensing meter, the user-identification data configured to identify a user;
