  • Publication number: 20230387963
    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.

  • Publication number: 20230118938
    Abstract: A breath detecting system and breath detecting mat thereof are disclosed. The breath detecting mat is placed under bed mattress and has a hollow board, a vibration sensor and a signal processing circuit. The vibration sensor and the signal processing circuit are mounted in the hollow board. The vibration sensor senses the micro-vibrations caused by the breathing of the person is lying on the bed mattress and outputs the breath sensing signal to the signal processing circuit. The signal processing circuit samples the sensing signal according to different moving average points to generate the fast-moving and slow-moving average signals. Since the first fast-moving and slow-moving average signals have many cross points, the signal processing circuit calculates each time difference between every two adjacent cross points. A present breath frequency is calculated according to the time differences. Therefore, the noises of the sensing signal are effectively removed.
