An ultra low power, low complexity, low collision, deterministic modulation method that also works as a massive medium access mechanism for communication systems is based on positioning data in a communication resource space, such as time and frequency, such that the position of a symbol in that space determines its value and its access to the medium. The number base of the symbol is determined by the size of the subset of the resource space it is positioning itself in and, thereby, a few sparsely located symbols can convey a large value, while the remainder of the space can be simultaneously and massively used by other sparsely resource using members of the network.

An efficient system and method for adaptive tile depth filter (ATDF) is disclosed. The key concept of this system and method is to consider more occlusion conditions in order to achieve a better performance of filter before the conventional Z test process in three dimensional graphics pipeline. Two occlusion criteria, Zmax and Zmin (depth range in a tile), are introduced first for occlusion and non-occlusion fragments in a tile. The points between Zmax and Zmin are in uncertain fragment which may need to go through the later Z test. Moreover, a new technique, coverage mask, can further filter the points in the uncertain fragment to a final uncertain fragment and non-occlusion fragment. Besides, the coverage mask can be used to efficiently decide which tile needs the further sub-tile depth filter.

The object of the invention is to enable inhibiting power consumption in a power saving mode in an image scanner more. Separately from linear CCD that is an optical sensor mounted inside the body provided with an original table having a surface on which an original is put, senses reflected light from the original on which a beam emitted from a light source is incident on the surface and converts it to an electric signal, an external light sensor that detects external light incident on the body via the surface from the outside of the body and outputs a detection signal is provided in the body. A controller in the body releases a power saving mode based upon a detection signal value from the external light sensor. Besides, the controller stops the supply of power to a light source and the linear CCD in case the power saving mode is turned on.

So, the transparency of the light-regulation membrane can be regulated from opaque to clear or reversely while the transmittance of the PDLC film being adjusted by the power, and then any light source passing through the light-regulation membrane can be controlled.

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 power saving apparatus and power saving method thereof are disclosed. The apparatus includes a power controller and a power outlet, wherein the power controller has a first signal transmission interface, said first signal transmission signal interface is used to detect the operation mode of a host machine by a second signal transmission interface of said host machine, and outputs a controlling signal according to the operation mode of said host machine. The power socket communicates with the power controller and switches the power-on or off according to the control signal. When the host machine is operated in non-working mode, the power socket will turn off the power supplied to the peripheral electrical devices of the host machines, so as to save the power consumption of the peripheral electrical devices of the host machines.

A signal measurement method for a mobile communication apparatus supporting multiple transmission interfaces to perform communication transmission in a heterogeneous network environment, system and a recording medium thereof. Changes in the signal strength of an active network transmission interface are employed to adjust signal measurement periods of other non-active network transmission interfaces, thereby reducing the signal measurement frequency of these non-active network transmission interfaces. Moreover, as for the situation that a specific transmission interface periodically reports the signal measurement result to a remote network server, the signal measurement time during the report can also be reduced. By solving the power consumption problem caused by frequently activating the signal measurement of the mobile communication apparatus, the efficacies of saving power and improving the standby time and talk time can be achieved.
