  • Electronic devices with distributed slot antenna structures
    Patent number: 12107335
    Abstract: An electronic device may have peripheral conductive housing structures, a display frame, a support plate, a logic board, and an antenna. The antenna may have a resonating element that includes a first slot between the logic board and a segment of the peripheral conductive housing structures, a second slot between the display frame and the segment, and optionally a third slot between the support plate and the segment. The slots may be at least partially overlapping, may have respective lengths, may be located at respective distances from a cover layer for the display, and may collectively receive radio-frequency signals in a frequency band such as the L5 GPS band. Switching circuitry and filter circuitry may be coupled to the antenna feed and/or to the antenna feed (s) of one or more adjacent antennas in the electronic device to help to isolate the antennas from each other.

  • Apparatus and method for increasing heat dissipation capacity of a medical instrument
    Patent number: 11744448
    Abstract: A method and apparatus for improving a heat dissipation capacity. An apparatus comprises an elongate member, a housing, and a heat pump device. The elongate member has a distal end and a proximal end. The housing is coupled to the proximal end of the elongate member. The heat pump device is disposed between the proximal end of the elongate member and the housing. The heat pump device is disposed at least partially outside the housing and is configured to transfer thermal energy between the elongate member and the housing. The heat pump device has a maximum outer diameter that is greater than a maximum outer diameter of the elongate member.
