  • Publication number: 20230386258
    Abstract: There is provided an optical sensor including a pixel matrix and a readout circuit. The pixel matrix includes multiple pixels arranged in a matrix, and each of the multiple pixels outputs temporal difference pixel data. The readout circuit sequentially reads the pixel matrix using a readout block, and performs the hybrid difference calculation on the temporal difference pixel data of pixels within the readout block. Accordingly, the output of the readout circuit is the data accomplishing temporal difference and spatial difference.

  • Patent number: 11803273
    Abstract: A touch sensor, a touch pad, a method for identifying an inadvertent touch event and a computer device are provided. A control circuit of the touch sensor identifies whether there is the inadvertent touch event in response to the touch signals that indicates at least one touch event applied to the touch pad having the touch sensor. In the method, the touch signals are discarded if the inadvertent touch event is identified when a touch position corresponding to the touch signals is within an object detection area defined for the touch pad, or the touch positions in response to the touch signals are reported to the computer device if a multi-touch event is identified when the touch positions are within a touch detection area defined for the touch pad.

  • Patent number: 11743691
    Abstract: A method and node for processing messages within an Internet of Things (IoT) network and network packet thereof are provided. Multiple fields of a header of a network packet broadcasted over the IoT network are referred to in the method. When a node receives a network packet broadcasted over the IOT network, it checks if the node's ID is recorded in an ID field of the network packet. The node ID is added to the network packet if the network packet does not record the node ID, and the network packet is then broadcasted to the IOT network; otherwise, the network packet is not broadcasted if the node ID has been recorded in the ID field. The node also performs a function indicated in a function field of the network packet when the node ID is not recorded in the network packet.
