摘要： An electronic device has a temperature sensor that detects temperature of a CPU, an image processing unit, and a microprocessor unit that controls the supply of electric power from a power source unit to the CPU and the image processing unit according to the temperature detected by the temperature sensor. If the temperature of the CPU and/or the image processing unit is detected by the temperature sensor to be near the temperature that causes malfunction or damage to them, the supply of electric power to the CPU and the image processing unit is automatically stopped by the microprocessor unit. It is possible to prevent malfunction and damage of the CPU and the image processing unit and to easily prevent the occurrence of runaway programs, etc.

摘要： The operating mode of a power modulation system is determined according to the nature of the load. The power modulation system can operate in either of two operating modes, namely a “reverse phase control” mode and a “forward phase control” mode. To this end, the load is supplied with power under predetermined low-load operating conditions by the power stage in the “reverse phase control” mode, overvoltages are detected and the power modulation system is caused to change to the “forward phase control” operating mode if an excessive number of overvoltages is detected.

摘要： A detection unit detects input-request signals or receive signals that correspond to the input-request signals that are sent and received between a specific data-processing apparatus and another apparatus. A judgment unit then determines whether the data-processing apparatus is performing a specific process, based on the status of the data-processing apparatus and detection results from the detection unit. A supply-control unit controls whether or not to supply a synchronization clock to the data-processing means according to judgment results from the judgment unit.

摘要： In a computer system having a plurality of power management states, a power management control circuit includes a power management controller which manages power in accordance with the Advanced Configuration and Power Interface (ACPI) power management scheme, and includes a switching circuit that supplies a main power or a standby power to a system memory for the computer system according to a control of the power management controller. When a system state of the computer system is converted into the soft off state of the ACPI power management scheme, the power management controller cuts off power supplied to the system memory for the computer system. Therefore, it is possible to prevent unnecessary power consumption and damage to the system memory and to peripheral circuits when the system memory is removed or mounted from or upon a main board for the computer system.

摘要： A PC includes a main body housing and lid. The main body housing has an input unit on the upper surface, and the lid pivotally attached to the back portion via a hinge. The lid has a liquid crystal display on the inner surface, and an antenna disposed above the display to communicate with a peripheral device. The PC has a detector made up of a push type switch and projection for detecting the open/closed state of the lid. The CPU of the PC detects the open/closed state of the lid by a detection signal from the detector, and controls shift of the peripheral device between a normal mode and a power saving mode.

摘要： A computer system that selectively disables power to wake on LAN (WOL) devices in the absence of AC power. In one embodiment, the computer system comprises a power supply and a power management controller. The power supply is configured to provide power to a wakeup device. The power management controller receives an AC voltage sense signal that indicates the presence or absence of an AC power source and enables the power supply to provide power to the wakeup device when the AC voltage sense signal is asserted. The power management controller preferably disables the power supply when the AC voltage sense signal is de-asserted. The computer system may operate in several states including an off state, a power on self test (POST) state, a working state, a trap state, and an armed state.

摘要： A coupling piece for carrying out digital transmissions between an electrical interface of a first device and an electrical interface of a second device. The devices each use different voltage levels for distinguishing between the two logical states “high” and “low”. An internal circuit is provided for converting the voltage levels of the first device to the voltage levels of the second device, which correspond to the state. The higher voltage level is conveyed to this internal circuit by one of the two devices so that the low level can be converted to the higher level. The internal circuit carries out the conversions using a switching process.

摘要： A method to reduce the power dissipation of a system by omitting an unnecessary CPU throttling operation in a power management apparatus that performs the CPU throttling operation. A power management apparatus 10 is constituted by an event detecting section 12 to detect an event in a system, an activity detecting section 14 to decide whether the system is in a busy state or in an idle state by checking whether or not there is activity in the system, and a clock control section 16 to execute CPU-clock control. The control section 16 does not perform an unnecessary CPU throttling operation, by stopping the CPU throttling operation when the system is in the idle state and performing the CPU throttling operation only when the system is in the busy state. With this, the power dissipation of the system can be considerably reduced.
