2results about How to "Less contention" patented technology

This invention provides a three-dimensional force data management method and system, relating to the management and communication of three-dimensional force data from tactile sensors. The method quantizes and compresses the X / Y / Z axis amplitudes of each three-dimensional force vector to 10 bits, and separately encodes the X and Y sign bits into 2 bits, forming a compact 32-bit representation of 10+10+10+2 bits. At the transmitting end, continuous three-dimensional force vector arrays are batch-packed into multiple 64-byte communication frames with 32-bit alignment and zero-copy, and then sent. At the receiving end, the three-axis force and direction information is quickly recovered through bitmasking and shifting. Simultaneously, addressing the bus contention problem caused by multiple nodes powering on in parallel, this invention utilizes a unique chip identifier and a hardware counter to generate multi-level random startup delays, enabling staggered initialization and transmission by multiple devices, thereby reducing frame loss and congestion. This invention has the advantages of data compression, fast parsing, low memory and bandwidth consumption, and high stability across multiple nodes, making it suitable for mass production deployment of tactile sensor products using real-time buses such as CAN / CAN-FD.
