    • A controller for detection of touches by a single finger or multiple fingers on a touch panel, the touch panel including a first group of electrodes arranged in a first direction and a second group of electrodes arranged in a second direction, thereby forming a plurality of crossover points. The controller includes: a plurality of signal drivers coupled to the first group of electrodes and configured to excite the first group of electrodes sequentially using a spread spectrum signal; a plurality of signal sensors coupled to the second group of electrodes and configured to detect peaks and troughs of capacitive coupled signals at the second group of electrodes, the detecting being performed simultaneously for the crossover points along a current one of the first group of electrodes that is being excited; and a signal processing device configured to detect the touches on the touch panel and to determine touch positions and touch movements, based on the detected peaks and troughs of the capacitive coupled signals.

    • A motor vehicle safety system for a motor vehicle having wheels and tires on the wheels includes a hydraulically extendable elongate arcuate member in an elongate arcuate housing extending around an upper portion of each tires, and a valve operable in response to an impact on the impact sensor to apply hydraulic pressure from an oil supply system to the arcuate housing to displace the arcuate member along the arcuate housing from a retracted position in the arcuate housing to an extended position in which the arcuate member projects from the housing with an end located beneath the tire. Alternatively, the arcuate member may be released for displacement by gravity into its extended position. Rollers projecting from the arcuate member are in rolling engagement with the tire and with the ground on displacement of the arcuate member into the extended position.
    • 一种用于在车轮上具有车轮和轮胎的机动车辆的机动车辆安全系统包括在每个轮胎的上部周围延伸的细长弓形壳体中的液压可伸长的细长弓形构件,以及响应于冲击传感器的冲击而可操作的阀 将来自供油系统的液压施加到弧形壳体,以将弓形构件沿着弓形壳体从弓形壳体中的缩回位置移位到延伸位置,在该延伸位置中,弓形构件从壳体突出并且位于轮胎下方的端部 。 或者,可以释放弓形构件以通过重力移位到其延伸位置。 从弓形构件突出的辊子与轮胎成一体地滚动,并且在将弓形构件移位到伸出位置时与地面滚动接合。
