  • Patent number: 10361594
    Abstract: A wireless power transmission device radiates electromagnetic waves through a transmission antenna and generates multiple sensed signals by using multiple foreign object detection (FOD) coils for detecting metallic foreign object to sense the electromagnetic waves. Each FOD coil has three coil units connected in series to and spaced apart from one another. The radiation pattern of the transmission antenna overlaps a sensing range of the FOD coils. A controller of the wireless power transmission device determines if any metallic foreign object enters the radiation range of the transmission antenna according to a reference voltage signal and sensed signals of the cells, and stops the generation of electromagnetic waves when determining entry of metallic foreign object into the radiation range to avoid the metallic foreign object to be heated by the electromagnetic waves.

  • Patent number: 10351115
    Abstract: An air brake relay valve includes an air guide unit having a movable set, a drive unit having a motor and a worm shaft, and a cam unit having a transmission member and a driven member. During a brake action, the motor rotates the worm shaft to rotate the transmission member so as to push the driven member downward to thereby move the movable set to a communicating position where a first valve opening and a second valve opening fluidly communicate with each other. When the brake action is released, the motor rotates reversely so that the driven member is moved upward and that the movable set moves, without being applied with additional force, to a non-communicating position where the first and second valve openings do not fluidly communicate.
