  • Patent number: 12002906
    Abstract: The present disclosure provides a semiconductor device and a semiconductor component. The semiconductor device includes an active structure, a ring-shaped semiconductor contact layer, a first electrode, and an insulating layer. The active structure has a first-conductivity-type semiconductor layer, a second-conductivity-type semiconductor layer, and an active layer located between the first-conductivity-type semiconductor layer and the second-conductivity-type semiconductor layer. The ring-shaped semiconductor contact layer is located on the second-conductivity-type semiconductor layer and having a first inner sidewall and a first outer sidewall. The first electrode has an upper surface and covers the ring-shaped semiconductor contact layer. The insulating layer covers the first electrode and the active structure and has a second inner sidewall and a second outer sidewall. The first inner sidewall is not flush with the second inner sidewall in a vertical direction.

  • Publication number: 20120182319
    Abstract: A system for changing the display direction of a screen includes a gravity sensor, a control key unit, a display control unit, and a control mode choice unit. The gravity sensor is adapted to generate gravity-sensing signals according to the orientation of the screen. The control key unit is adapted to generate a control instruction. The control mode choice unit is connected to the gravity sensor and the control key unit. The control mode choice unit is adapted to send either the gravity sensed signal from the gravity sensor or the control instruction from the control key unit to the display control unit. The display control unit is adapted to control the display direction of the screen according to either the gravity sensed signal or the control instruction.

  • Publication number: 20120176339
    Abstract: A system for generating click input signal for optical finger navigation, includes a touch sensor, a timing unit, and a control unit. The touch sensor is adapted to sense whether a finger presses thereon. The timing unit is adapted to time a duration time of the finger pressing on the touch sensor when the finger presses on the touch sensor. The control unit is adapted to generate a first click signal when the duration time is greater than a threshold value and generate a second click signal when the duration time is smaller than a threshold value.

  • Publication number: 20120052927
    Abstract: A system for managing power supply of a mobile device, includes a random access memory, a storage device, and a battery. The random access memory will not store information therein without power. The storage device can store information therein regardless of power supplied to the storage device. The storage device is connected to the random access memory. The storage device includes an image area. The battery is connected to the random access memory and the storage device. The mobile device is configured to work between a normal mode and a first power-saving mode. In the normal mode, the battery supplies power to the random access memory. In the first power-saving mode, information stored in the random access memory is copied into the image area, and the battery stops providing power to the random access memory.

  • Publication number: 20120049631
    Abstract: A power supply system includes an adapter adapted to covert AC power into DC power, a power supply chipset connected to the adapter, a main battery, a slave battery, and a control chipset connected to the power supply chipset, the main battery, and the slave battery. The power supply chipset is adapted to receive DC power provided by the adapter. The control chipset is configured to monitor whether the power supply chipset receives DC power. The power supply chipset can provide DC power to the electronic device system and charge the main battery and the slave battery when the power supply chipset receives DC power. The power supply chipset also can control the main battery and the slave battery providing power to the electronic device system when the power supply chipset does not receive DC power.
