  • Publication number: 20240079485
    Abstract: A high electron mobility transistor device including a channel layer, a first barrier layer, and a P-type gallium nitride layer is provided. The first barrier layer is disposed on the channel layer. The P-type gallium nitride layer is disposed on the first barrier layer. The first thickness of the first barrier layer located directly under the P-type gallium nitride layer is greater than the second thickness of the first barrier layer located on two sides of the P-type gallium nitride layer.

  • Patent number: 9886147
    Abstract: An electronic device includes a storage unit, a touch-sensing unit and a processing unit. The storage unit stores a plurality of combinations of at least two shapes. The touch-sensing unit detects the touch of a first touching object and a second touching object while the electronic device is in an idle mode. The touch-sensing unit further generates a sensing signal when the capacitance values corresponding to the first touching object and the second touching object are within a predetermined range over a predetermined time, and the combination of the shapes of the first touching object and the second touching object conforms to one of the combinations stored in the storage unit. The processing unit enables an application program according to the sensing signal.

  • Patent number: 7244054
    Abstract: A direction indication light installed on a handle of a car door comprises a body; a front edge thereof installed with a receiving groove; the receiving groove received with a plurality of circuit boards, a light guide plate, and a cover; each circuit board being installed with light emitting body; upper sides of the circuit boards being installed with a light guide plate for receiving the circuit boards; the power wires of the circuit boards serve to light up the light emitting body of at least one of the circuit boards. By the indication light, the periphery of the car is lighted up so that cars at the periphery of the car can keep attention to the state of the car to prevent from collision due to weak view.
