Abstract

A detector for detecting the removal and/or insertion of a firearm out of and/or into a holster. The detector may transmit a message each time the firearm is removed from the holster. A recording system may receive the message and determine whether or not it will begin recording the data it captures. A detector may detect the change in a magnitude of an inductance and/or an impedance of a circuit to detect insertion and removal of the firearm into and out of the holster. The holster is configured to couple to the detector to position the detector to detect insertion and removal of the firearm.

First claim

What is claimed is:

1. A method performed by a detector for detecting at least one of removal and insertion of a firearm into and from a holster, the method comprising:
responsive to detecting a first activation of a control, entering a test mode;
responsive to detecting a third activation of the control, entering a reset mode;
while in the test mode:
detecting a first characteristic of a signal provided by a sensor that indicates insertion of the firearm in the holster;
detecting a second characteristic of the signal provided by the sensor that indicates removal of the firearm from the holster; and
responsive to detecting a second activation of the control, entering a field mode;

while in the field mode:
responsive to detecting the second characteristic of the signal provided by the sensor, transmitting a message; and

while in the reset mode:
resetting an operation of the detector; and
entering the test mode.

2. The method of claim 1 further comprising:
while in the test mode: responsive to detecting the second characteristic, activating an indicator.

3. The method of claim 1 further comprising:
while in the test mode: responsive to detecting the first characteristic, activating an indicator.

4. The method of claim 1 wherein the first activation comprises a single press activation.

5. The method of claim 1 wherein the second activation comprises a long press activation.

6. The method of claim 1 wherein:
the second activation comprises a long press activation;
the third activation comprises a longer press activation; and
the control is operated for a longer period of time during the longer press activation than the long press activation.

7. The method of claim 1 further comprising:
while in the test mode: responsive to detecting a fourth activation of the control, entering a calibration mode; and
while in the calibration mode:
determining the first characteristic of the signal provided by he sensor that indicates insertion of the firearm in the holster;
determining the second characteristic of the signal provided by the sensor that indicates removal of the firearm from the holster; and
entering the test mode.

8. The method of claim 7 wherein the fourth activation comprises a double press activation.

9. The method of claim 7 wherein determining the first characteristic comprises determining a magnitude of at least one of an inductance and an impedance that indicates that the firearm is positioned in the holster.

10. The method of claim 7 wherein determining the second characteristic comprises determining a magnitude of at least one of an inductance and an impedance that indicates that the firearm is positioned out of the holster.

11. The method of claim 1 further comprising:
responsive to detecting a fifth activation of the control, entering a rollback mode; and
while in the rollback mode:
selecting for execution a previous version of software of the detector; and
entering the reset mode.

12. The method of claim 11 wherein the fifth activation comprises a very long press activation.

13. A method performed by a detector for detecting removal of a firearm from a holster, the detector includes a communication circuit, a sensor circuit, and a control, the method comprising:
while operating in a field mode:
responsive to detecting a first signal, transmitting a message, the message having a mute bit set to a first value of zero, the sensor circuit provides the first signal in response to detecting removal of the firearm from the holster, the communication circuit transmits the message; and
responsive to detecting activation of the control, entering a mute mode, the control manually operated by a user; and

while operating in the mute mode:
responsive to detecting the first signal, transmitting all the message, the message having the mute bit set to a second value of one, the communication circuit transmits the message; and
responsive to detecting expiration of a duration of time, entering the field mode.

14. The method of claim 13 wherein detecting removal of the firearm comprises detecting a change in a magnitude of an impedance of a circuit.

15. The method of claim 13 wherein detecting activation of the control comprises detecting operation of a button.

16. The method of claim 13 wherein detecting expiration of the duration of time comprises counting down a timer.

17. The method of claim 13 wherein transmitting the message comprises transmitting the message wirelessly.

18. The method of claim 13 wherein:
while in the field mode: transmitting the message comprises transmitting one or more messages, each message has the mute bit set to the first value; and
while in the mute mode: transmitting the message comprises transmitting one or more messages, each message has the mute bit set to the second value.
