Data segmentation using shift-varying predicate function fingerprinting
Shift-varying segmentation uses a shift-varying predicate function to evaluate input data within a sliding window to determine if the current sliding window position should be a segment boundary.

As the sliding window position advances away from a previous segment boundary, the probability of a segment boundary at the window position increases. Shift-varying segmentation can be used in compression, transaction acceleration, and data storage applications. |

A unilateral feedback power amplifier utilizes new feedback techniques and devices to make the amplified high-frequency signal unilateral, let the output power, power gain and impedance matching simultaneously accomplish the optimal values, and enhance the stability of the system. In this feedback amplifier, a generalized multi-port feedback circuit is in shunt with the input terminal and the output terminal of the power transistor. This generalized multi-port feedback circuit receives an amplified high-frequency signal and eliminates the reverse admittance of the amplified high-frequency signal to let the admittance value of the output amplified high-frequency signal approach zero so as to be unilateral. Moreover, the generalized multi-port feedback power amplifier differs from the conventional power amplifier of cascaded architecture in that the ground terminal of the power transistor is directly connected to the system ground.

Eliminating metal-rich silicides using an amorphous Ni alloy silicide structure
The present invention provides a method for producing thin nickel (Ni) monosilicide or NiSi films (having a thickness on the order of about 30 nm or less), as contacts in CMOS devices wherein an amorphous Ni alloy silicide layer is formed during annealing which eliminates (i.e., completely by-passing) the formation of metal-rich silicide layers.

A tensile-stress-generating structure is formed above a gate electrode in a CMOS image sensor to apply a normal tensile stress between a charge collection well of a photodiode, which is also a source region of a transfer transistor, and a floating drain in the direction connecting the source region and the floating drain.

Recycle of electrical equipment
The conventional techniques for recycling an electrical equipment including a hardened epoxy resin and electroconductive material has involved conventional problems that a catalyst is degraded to an extent that it can be no longer reused when a water is contained in a dissolving system. Moreover, moisture, when present in the dissolving system for treating an electrical equipment including an electroconductive material of aluminum, may react with aluminum to produce an aluminate compound which is transformed into aluminum oxide (alumina) under heating, which, in turn, may cause abnormal temperature rise to melt aluminum.
