  • Publication number: 20250029481
    Abstract: A sensor device, a holster sensing system, and a video-recording system are provided. The sensor device includes a control unit and a sensing module. The sensing module includes a reference coil set and an induction coil set that are arranged in a stacked structure. The sensing device is fixed on a holster. The induction coil set is configured to be adjacent to the holster. The control unit determines whether a gun is in the holster according to an inductance change between a sensing value generated by the induction coil set and a reference level provided by the reference coil set. In an application of the video-recording system, the control unit transmits a trigger signal to a recording device if the gun is determined to be pulled out of the holster according to the inductance change, so that the recording device is activated to start recording.

  • Patent number: 12149299
    Abstract: Systems and methods are provided for synchronizing multiple channels in an access network, where the multiple channels are neighboring channels such that a guard band between them or use of a diplexer to prevent inter-channel interference is not required. Synchronization is achieved by defining channel MAP (media access plan) cycle structures such that all channels work in the same direction (upstream US or downstream DS) at any given time. Moreover, the network controller of channel may send out a beacon to allow new nodes to join. A long MAP cycle (402) may be followed by three consecutive regular MAP cycles (404, 406), and (408). These MAP cycles are repeated between beacon transmissions. Synchronization allows multiple channels to be configured contiguous (without a guard band between neighbouring channels) and without utilizing diplexers. A plurality of customer premises equipment may operate on each of the communications channels.
