  • Publication number: 20250138188
    Abstract: An unmanned vehicle processing system includes a controller, a laser source, a galvanometer module and a receiving device. The controller provides a laser trigger signal. The laser source is connected electrically to the controller, receives the laser trigger signal and further emits accordingly a laser beam. The galvanometer module includes a scanning galvanometer for reflecting and converting the laser beam into a processing beam.

  • Patent number: 11916282
    Abstract: An antenna apparatus includes a feeding antenna inside an electronic device and one or more antenna elements, such as a floating metal antenna, disposed on a rear cover of the electronic device. The floating metal antenna and a feeding antenna inside the electronic device may form a coupling antenna structure. The feeding antenna may be an antenna fastened on an antenna support (which may be referred to as a support antenna). The feeding antenna may alternatively be a slot antenna formed by slitting on a metal middle frame of the electronic device. The antenna apparatus may be implemented in limited design space, thereby effectively saving antenna design space inside the electronic device. The antenna apparatus may generate excitation of a plurality of resonance modes, so that antenna bandwidth and radiation characteristics can be improved.
