  • Ultrasonic sensing device and the manufacturing method thereof
    Patent number: 11476404
    Abstract: An ultrasonic sensing device includes a housing, a piezoelectric assembly, a board and a plurality of fixing members. The housing includes a bottom wall, a top wall and a surrounding side wall connected between the top wall and the bottom wall. The piezoelectric assembly includes an encapsulating body and a piezoelectric sheet, wherein at least a portion of the piezoelectric sheet is enclosed by the encapsulating body and has a sensing surface exposed to the encapsulating body and facing the bottom wall. The board is disposed on the top wall of the housing and has a pressing surface facing the encapsulating body and the top wall. The plurality of fixing members is configured to fix the board to the top wall of the housing to press the board to the encapsulating body of the piezoelectric assembly, thereby pressing the sensing surface of the piezoelectric sheet to the bottom wall.

  • POWER CONVERTER SWITCHABLE BETWEEN DIFFERENT POWER CONVERSION MODES
    Publication number: 20200036278
    Abstract: A power converter includes a mode switch cell which is provided with AC power or DC power, and a converter circuit which has an AC input port and a DC input port. The mode switch cell is operable to relay the AC power to the AC input port or to relay the DC power to the DC input port. The converter circuit is configured to generate a DC power output by performing AC-to-DC conversion on the AC power, or performing DC-to-DC conversion on the DC power.
