Abstract:
In an electronic system and a power supply device thereof, the power supply device supplies electric power to an electronic device in the electronic system. When the electronic device is shut down, the electronic device transmits a shutdown signal to the power supply device, so that the power supply device stops supplying electric power to the electronic device. And, when the electronic device is switched on, the electronic device transmits a start signal to the power supply device, so that the power supply device starts supplying electric power to the electronic device. Therefore, power consumption by the power supply device when the electronic device is shut down can be reduced.
Abstract:
A panel device mounted on a computer case comprises an adjustment unit for adjusting CPU's operating frequency, a display module for showing system information, and a microprocessor which interconnects the adjustment unit and the display module with the computer system. The microprocessor can perform adjustment done by the adjustment unit and issue a service request signal to the computer. In response, the computer issues signals about system information to the microprocessor for being processed and showed on the display module.
Abstract:
A system, and an apparatus of speaker, and a method for forming a virtual audio is provided. An audio source is processed by a second audio source processing program according to parameters which are entered by the user, and filtered to be a high frequency audio signal. The audio source with orientation is outputted by the orientation speaker.
Abstract:
An electronic apparatus using NAND flash memory and a memory management method thereof are provided. The electronic apparatus uses the NAND flash memory to record data in the system memory. In the present method, when a standby instruction is received, a fast flash standby (FFS) procedure is initiated, and a state of the NAND flash memory is checked to determine whether the NAND flash memory is suitable for recording the data in the system memory. If the state is determined as suitable for recording the data, the data in the system memory is copied to the NAND flash and the operating system of the electronic apparatus is controlled to enter a hibernate mode. On the contrary, if the state is determined as not suitable for recording the data, the operating system of the electronic apparatus is controlled to enter a standby mode.
Abstract:
A portable apparatus includes a display housing, a main housing, and a sound output device. The display housing has a pivot side. The main housing includes a pivot portion that defines a pivot axis and that is coupled to the pivot side of the display housing such that the display housing is pivotable relative to the main housing about the pivot axis. The pivot portion is formed with a receiving space. The sound output device is disposed in the receiving space of the pivot portion and outputs sound in a sound propagating direction substantially parallel to the pivot axis.
Abstract:
An electronic device and an external power supply device control method applicable to the electronic device are disclosed. The electronic device is electrically connected to an external power supply device that is able to switch between an ON state and an OFF state. The electronic device includes a switch module and an internal power module. The switch module, when being triggered, generates a switch signal. The internal power module receives the switch signal and accordingly generates a trigger signal to the external power supply device, so that the external power supply device is triggered to switch from the OFF state to the ON state and accordingly supplies electric power to the electronic device.
