摘要:
A manufacturing method for manufacturing ceramic electronic components, includes steps of forming a stack body by stacking ceramic green sheets and conductive layers on top of each other, punching a frame into the stack body and holding the frame in the stack body, locating a pressing force applying member inside the frame and, while the frame is held in the stack body, applying a pressing force to a portion of the stack body located inside the frame by causing the pressing force applying member located inside the frame to press against the portion of the stack body located inside the frame, to thereby form a high-density structure inside the frame while preventing the high-density structure from deforming outwardly beyond the frame. The stack body can be heated to reduce the required pressing force, and an elastic member may be provided to make the pressing force uniform.

A method and system are provided for thermal management of a portable computing apparatus. Accelerometers are provided to detect changes in attitude, and temperature sensors are provided to detect changes in temperature. A fan is used to cool the internal temperature of the electronic components of the computer. In response to lift of the computer from a stationary surface, the computer may transition to an alternative state of operation. The transition may include the change of the speed of the fan and/or adjustment of the processor clock.

Power usage of computing device components is controlled in a holistic manner. The projected total power consumption for the computing device to satisfy a power consumption policy for the device is determined. Power usage of each component of the computing device is controlled in a holistic manner—i.e., balancing the power usage of the component against the power usage of other components—so that the total power usage of the computing device falls within the projected total power consumption needed to satisfy the power consumption policy. How the user is currently utilizing the computing device may be periodically detected, based at least on a power consumption distribution of the components of the computing device. A current usage model is determined based on how the user is currently utilizing the computing device. The power usage of each component of the computing device is controlled based on the current usage model.

Systems, methods and products directed toward coordinating power states in a hybrid information handling device are described herein. One aspect includes a method including: providing a primary operating environment and a secondary operating environment in an information handling device; ascertaining a trigger event for switching between the primary operating environment and the secondary operating environment; providing power state transitioning responsive to the trigger event; and placing one of the primary operating environment and the secondary operating environment in a working state while one of the primary operating environment and the secondary operating environment is in a sleeping state. Other embodiments are described herein.
摘要:
A portable computer having a biometric authentication device is disclosed. The portable computer also includes a processor, a power supply unit having a first power system and a second power system, a power control circuit for controlling the power supply unit, and a start-up button for generating a startup signal for starting the portable computer. The biometric authentication device sends a power request signal to the power control circuit to activate the second power system upon a detection of a human user in a state where the second power system is deactivated and electric power is being supplied by the first power system. The biometric authentication device can perform an authentication operation while receiving electric power from the second power system, and the power control circuit causes the portable computer to transition to a power-on state in response to an authentication success by the biometric authentication device.

The invention realizes the execution of a predetermined process just before the turn-off of the power of a computer, without incurring increase in the load.A shutdown reset logic 52 is provided between a power management unit 68 on a core chip and a power circuit 54. The logic 52 is enabled just before the system is shut down, and it interrupts the inputting of a power-off signal −SUSC output from the power management unit 68 to the power circuit 54, inputs a signal LAST#PWG#PIIX4 representing a faulty power state to the power management unit 68 to cause a hardware reset, and inputs a signal −PERSW#PIIX4 representing the turn-on of a power switch 92. This causes the POST to be started, and the POST turns off the power of the system after enabling the WOL function of the network adapter.
