The PDP disclosed herein has a plurality of thin wire electrodes extending in the row direction, which are laid out in such a way as to widen the interval at a fixed ratio (2 times) from the discharge gap section toward the non-discharge gap section as well as to shorten the lengths of those row direction thin wire electrodes in steps with a fixed difference (approximately 20 mumxleft/right) from the cell's vertical center axis toward the partition walls. They are connected by thin wire electrodes that extend in the column direction to form antenna-shaped plane electrodes and the thin wire electrodes that extend in the column direction from the center of the antenna-shaped plane electrodes and the bus electrodes that extend in the row direction are connected to form a sustaining electrode pair (scan electrode and common electrode).

In order to avoid loss of data, computer systems are often connected to a UPS which provides power backup in case of an emergency shutdown resulting from a power failure. However, as UPS units are costly, they take up a lot of physical space and can provide power for a limited period of time, it would be advantageous to improve the efficiency of UPS devices and enable to utilize as much as possible of the UPS power in order to save data to a permanent storage before shutdown. There is provided a method and system for controlling the frequency of one or more processors in computer systems, responsive to an indication of a power failure, and thereby reduce its power consumption, so as to provide more power for writing write-pending data to a non-volatile data storage.

A calendar timer mechanism has an OFF mode for turning off all objects to be controlled, which include a heater, a display panel, and motors, an ON mode for turning on all the objects to be controlled, and at least two energy-saving modes for selectively turning off the objects to be controlled or turning on the objects to be controlled at a lower power consumption rate. Transitional times between at least three of the OFF mode, the ON mode, and the energy-saving modes can be set as desired.

An aspect of the present invention proposes a solution to allow a dynamic adjustment of a performance level of a GPU based on the user observed screen area. According to one embodiment, a user's focus in one or more display panels is determined. The GPU that performs rendering for that region and/or display panel will dynamically adjust (i.e., increase) the level of performance in response to the user's focus, whereas all other GPUs (e.g., the GPUs that perform rendering for other regions/display panels) will experience a reduced level of performance. According to such an embodiment, dynamically reducing the performance of GPUs outside of the area of focus can result in any one or more of a significant number of benefits, including lower power consumption rates, less processing, less (frequent) memory accesses, and reduced heat and noise levels

The present invention discloses a power-efficient backbone-oriented wireless sensor network, a method for constructing the same and a method for repairing the same, wherein energy-rich nodes are used to form backbones linking to a server, and wherein regular nodes having limited energy storage link to the backbones. When one energy-rich node malfunctions, the energy-rich node, which is posterior to the malfunctioning energy-rich node, searches for and links to a linkable neighboring energy-rich node on the backbone. If there is none linkable neighboring energy-rich node, the regular nodes are used to form a temporary tunnel until the malfunctioning energy-rich node has been repaired. The present invention can relieve the influence of hot spots, increase the robustness of the wireless sensor network, and prolong the service life of the wireless sensor network.

The operation of a HEMT is monitored on an on-chip basis without increasing the power consumption rate. In a semiconductor device 10, an electron supply layer 12 is formed on a channel layer 11. A two-dimensional electron gas (2DEG) layer 13 is formed at the side of the channel layer of the hetero-junction interface. Electrons flow through the 2DEG layer 13 between a source electrode 14 formed on the surface of the electron supply layer 12 and a drain electrode 15 that is formed on the same surface. A potential detection electrode 17 is arranged on the electron supply layer 12 between the gate electrode 16 and the source electrode 14. A resistor 18 having a sufficiently high resistance value makes the electric current flowing to the potential detection electrode 17 negligible relative to the drain current in operation.
