Abstract:
Systems and methods for recording and playback of multiple data streams. One device includes a storage controller coupled to an electronic storage device, a first data buffer storing data received from a first data stream, a second data buffer storing data received from a second data stream, a fragment buffer storing fragment metadata, a storage buffer including a plurality of data fragments, and an electronic processor. The electronic processor receives information designating a data stream storage area of the electronic storage device. The electronic processor arbitrates between the first and second data buffers to select a data fragment for writing to the storage buffer. The electronic processor writes the data fragment to the storage buffer, and writes fragment metadata defining the data fragment to the fragment buffer. The electronic processor controls the storage controller to sequentially write from the plurality of data fragments to the data stream storage area.

Abstract:
Methods and systems to increase protection of personnel during K9 deployments include receiving contextual and situational data from mobile devices associated with a plurality of officers at a scene, a mobile device associated with a K9 handler at the scene, and a device associated with a K9 at the scene, wherein each of the mobile devices and the device are communicatively coupled to one or more networks; determining safety conditions of each of the plurality of officers based on the contextual and situational data; and notifying any of the plurality of officers and the K9 handler via the associated mobile devices of unsafe conditions based on the determining.
