  • Publication number: 20200202087
    Abstract: A radio frequency (RF) positioning system comprises transceivers, positioning tags, processing units and a computing host. One or multiple positioning tags are attached to a target object being located. When the transceivers first generate and transmit transmission signals, one or multiple tag antennas in the positioning tag receive the transmission signals and transmit back modulated signals. The transceivers then receive and transmit the modulated signals to the processing units. The processing units are configured to obtain received signals, and calculate frequency differences based on the received signals and the transmission signals. The computing host calculates position coordinates of tag antennas based on the frequency differences, and then calculates the orientation of the target object being located according to the position coordinates of the tag antennas.

  • Patent number: 10658137
    Abstract: A key structure includes a support shaft, a resilience sheet, a pedestal and a keycap. While the keycap is pressed down in response to an external force, the support shaft is moved downwardly and the resilience sheet is correspondingly moved. Since a resilience part of the resilience sheet is pushed by a push part of the pedestal, the resilience part is subjected to deformation. After the resilience part is moved across the push part, the resilience part is elastically restored and swung. Consequently, the resilience part collides with the inner surface of the sliding groove to generate a click sound.
