  • Publication number: 20240113809
    Abstract: The present application provides an instruction encoding-based data processing method and apparatus, and a device. N-path error correction encoding is performed on an instruction in information to be processed to obtain N encoded instructions, the encoded instructions and encoded meta channel programs obtained by the error correction encoding are used to perform redundant processing on data to be processed to obtain N pieces of response data, and then error correction decoding is performed on the N pieces of response data to obtain processing result information of the information to be processed. Because the N encoded instructions are heterogeneous and the encoded meta channel programs used in the N-path processing are heterogeneous, the randomness of the processing process can be improved, generalized disturbance in the data processing process can be corrected in combination with the error correction encoding and decoding methods, and thus the security of data processing is improved.

  • Patent number: 9959719
    Abstract: An entry sensor, which supports either wireless or wired operation, facilitates installation and is adjustable for gaps between a building entry barrier such as a door or window and the surrounding frame. The sensor, which may be implemented as a single piece design, includes an adjustment mechanism that enables an installer to vary the extension of the sensor to match the actual gap so that the sensor properly secures the building entry when closed. The sensor includes a detector that determines the state of a switch that is responsive to the movement of a plunger mechanism, where the state is indicative whether the building entry barrier is opened or closed, and that may determine whether the sensor is tampered with. The sensor also may facilitate battery replacement that protects the associated circuitry during the replacement.
