Abstract

Systems and methods for presenting incident information provided by video devices and electronic weapons. Information may be selected for presentation by a machine or a human operator. Information from video devices and/or electronic weapons may be temporally aligned (e.g., synchronized) for presenting events that occurred in a temporally related manner. Information for aligning may be collected by a server and/or a video device.

4. The method of claim 1 wherein determining a second difference in time comprises:

requesting a present time of the second real-time clock of the electronic weapon;

receiving the present time of the second real-time clock of the electronic weapon; and

adjusting the received present time of the electronic weapon to account for a communication delay.

5. The method of claim 1 wherein providing electronic access comprises driving a display in accordance with the presentation.

6. The method of claim 1 wherein providing electronic access comprises transmitting the presentation for display.

7. The method of claim 1 wherein, in accordance with the log, the presentation comprises a graphic of an information.

8. The method of claim 1 wherein, in accordance with the log, the presentation comprises a graphic of a total quantity of pulses of current provided through the target.

9. The method of claim 1 wherein, in accordance with the log, the presentation comprises a bar chart of a quantity of pulses of current provided through the target.

10. A method performed by a server for presenting in a time-aligned manner a recording and a description of use of each electronic weapon of a plurality of electronic weapons, the recording captured by a video device at the scene of an incident, the recording comprising a plurality of time-stamps provided by a first real-time clock of the video device, the description comprising, for each particular electronic weapon, a plurality of time-stamps that each relate to provision of one or more pulses of current through a target with reference to a real-time clock of the particular electronic weapon, the method comprising:

determining a first difference in time between the first real-time clock of the video device and a third real-time clock of the server;

determining a respective second difference in time between a respective second real-time clock of each electronic weapon and the third real-time clock of the server;

in accordance with the first difference in time and each respective second difference in time, aligning a portion of a received video recording to a provision of current through the target to form an aligned information; and

providing electronic access to the aligned information for presentation.

11. The method of claim 10 wherein determining a first difference in time comprises:

requesting a present time of the first real-time clock of the video device;

receiving the present time of the first real-time clock of the video device; and

adjusting the received present time to account for a communication delay.

12. The method of claim 10 wherein determining a second difference in time comprises:

requesting a present time of the respective second real-time clock of each electronic weapon;

receiving the present time of the respective second real-time clock of each electronic weapon; and

adjusting the received present time of each electronic weapon to account for a communication delay.

13. A server for preparing a presentation of a recording and a log of an electronic weapon in a time aligned manner, the recording captured by a video device at the scene of an incident, the recording comprising a plurality of time-stamps provided by a first real-time clock of the video device, the log of the electronic weapon comprising a plurality of time-stamps that relate to provision of one or more pulses of current through a target with reference to a second real-time clock of the electronic weapon, the server comprising:

a processing circuit; and

a real-time clock;

wherein

the processing circuit determines a difference in time between a first real-time clock of the video device and a second real-time clock of the electronic weapon with reference to a third real-time clock of the server;

from the recording, selects for the presentation a frame having a first time-stamp; and

from the log, selects for the presentation an entry having a second time-stamp, selecting being in accordance with the first time-stamp of the recording and the difference in time.

14. The server of claim 13 wherein the server:

requests a present time of the first real-time clock of the video device;

receives the present time of the first real-time clock of the video device; and

adjusts the received present time to account for a communication delay.

15. The server of claim 13 wherein the server:

requests a present time of the second real-time clock of the electronic weapon;

receives the present time of the second real-time clock of the electronic weapon; and

adjusts the received present time to account for a communication delay.

16. A method performed by a video device for aligning a recording captured by the video device with a log of an electronic weapon, the recording comprising a first time stamp with reference to a first real-time clock of the video device, the log of the electronic weapon comprising a second time stamp that relates to provision of one or more pulses of current through a target, the second time stamp with reference to a second real-time clock of the electronic weapon, the method comprising:

determining a difference in time between the first real-time clock of the video device and the second real-time clock of the electronic weapon;
