  • Patent number: 11956887
    Abstract: A board, including a first pad area, a second pad area, a first micro heater, a second micro heater, a first heater terminal pad, a second heater terminal pad, and a third heater terminal pad, is provided. The first pad area and the second pad area respectively include at least one pad. The first micro heater and the second micro heater are respectively disposed corresponding to the first pad area and the second pad area. The first heater terminal pad and the second heater terminal pad form a loop with the first micro heater by being electrically connected to an outside, so that the first micro heater generates heat. The second heater terminal pad and the third heater terminal pad form another loop with the second micro heater by being electrically connected to the outside, so that the second micro heater generates heat. A circuit board and a fixture are also provided.

  • Patent number: 8404374
    Abstract: An electronic device with a battery cover waterproof structure includes a body having a first end and a second end, a battery compartment disposed in the body, a waterproof gasket disposed in the battery compartment, and a battery cover coupled to the body. The waterproof gasket includes an oblique engage surface, and one end of the oblique engage surface near the first end is elevated higher than the other end of the oblique engage surface near the second end. The battery cover has an oblique rib arranged corresponding to in the oblique engage surface. One end of the oblique rib near the first end is elevated higher than the other end of the oblique rib near the second end. The oblique rib will interfere with the oblique engage surface for sealing the battery compartment when the battery cover is pushed towards one end of the battery compartment near the first end.
