  • Patent number: 12365206
    Abstract: A TPMS transmitter (100) fixing structure, comprising a valve stem and a core rod (200) in the middle of the valve stem, the core rod (200) having a connector suitable for connecting to the TPMS transmitter (100), and also comprising a protruding part protruding outward along the radial direction of the valve stem, such that, when the valve stem is mounted on a wheel rim (300) of an automobile, the protruding part is in contact with the wheel rim (300); adding a protruding part to the valve stem can counteract the rotational torque produced by the eccentricity and centrifugal force of the transmitter to forcefully prevent rotation of the transmitter during operation, and limits the mounting direction of the TPMS transmitter, ensuring that the TPMS transmitter is not biased when mounted on the wheel rim, and effectively reducing the risk of the loss of function or reduction in performance of the TPMS transmitter due to biased or backward mounting of the TPMS transmitter.

  • Patent number: 12277975
    Abstract: A method of operating a non-volatile memory including an unselected word line is provided. A first voltage rising at a first slope is applied by a voltage generator to the unselected word line. Outputting the first voltage is stopped by the voltage generator in response to that the first voltage rises to a predetermined voltage, wherein the predetermined voltage is higher than a pass voltage. The pass voltage is outputted by the voltage generator to the unselected word line.

  • Patent number: 11935615
    Abstract: A sample and hold scheme for temperature measurements for non-volatile memory can enable significant reduction in temperature readout latency. In one example thermometer circuits are enabled at a refresh rate to cause the temperature to be sensed and latched at regular intervals. By performing the temperature readings in the background at a refresh rate instead of on-demand, the temperature is available to service commands with almost no latency.
