A write driver circuit including a plurality of programmable fuses for a phase change memory device in which a write operation is correctly performed even in the case where a current output shift in a write current generation circuit; or in the case where a phase change memory cell having a phase change property shift due to an external factor or due a process change. The write driver circuit includes a write current control unit for outputting a first or second level of voltage selected, by selecting one of a first or second programmable current path, based on whether a first or second selection pulse signal is applied; and a current driving unit for generating a write current controlled by the output voltage of the write current control unit. Each of the first and second programmable current paths includes fuses that can be programmed to adjust their resistance to adjust the respective selected output voltage to compensate for the current output shift in the write current generation circuit or for the phase change memory cell having the phase change property shift.

An electrically controlled light modulator device comprises at least one cell, where two deformable dielectric layers meet at an interface, at least one of said layers consisting of viscoelastic relief forming gel. A first support electrode structure and a second signal electrode structures are arranged on separate sides of the dielectric layers in order to create an electric field passing through said layers and in order to create surface reliefs on the viscoelastic gel layer. According to the invention, a third enhancement electrode structure is arranged in the proximity of the first signal electrode structure. Applying enhancement signal voltage between the enhancement electrode structure and the signal electrode structure concentrates locally the electric field passing through the two deformable dielectric layers and therefore enhances the amplitude of the deformation of the viscoelastic gel layer.

A shift circuit of a shift register includes an output terminal, an input terminal, a reset terminal. A voltage is applied to a first wiring in response to the output signal from the preceding stage shift circuit to the input terminal and in accordance with the predetermined voltage to the first wiring, outputting an externally applied signal to the output terminal. A voltage level of the first wiring is reduced in response to the output signal to the reset terminal by the preceding stage shift circuit. The voltage is applied to the second wiring in response to a change in the level of the voltage applied to the first wiring. The voltage is applied to a second wiring in response to the output signal to the reset terminal by the preceding stage shift circuit. A voltage level of the output signal is reduced in response to the predetermined voltage to the second wiring.

A pressure-sensitive adhesive label has a base having an information indication portion on its one surface thereof, and a pressure-sensitive adhesive layer formed on another surface of the base. After peeling a release liner, the label is stuck on an outer surface of a housing of the hard disk drive to reduce noise generated when the hard disk drive is driven. The release liner for coating the pressure-sensitive adhesive layer has an antistatic function and a cut line. The adhesive force of the adhesive layer is reduced by heating. The label has a surface density of not lower than 0.18 (kg / m2).

A silicon-insulator-silicon capacitive (SISCAP) optical modulator is configured to provide analog operation for applications which previously required the use of relatively large, power-consuming and expensive lithium niobate devices. An MZI-based SISCAP modulator (preferably a balanced arrangement with a SISCAP device on each arm) is responsive to an incoming high frequency electrical signal and is biased in a region where the capacitance of the device is essentially constant and the transform function of the MZI is linear.

Systems and methods for detection of charge switching element failure (e.g., charge FET switching element) in a battery system, such as a battery system of an information handling system (e.g. notebook computer), in which an increase in cell voltage is employed as a criteria for detecting charge switching element failure.

A battery charger controller is coupled to DC output terminals of an AC-DC (or DC-DC) adapter containing an AC-DC (or DC-DC) converter. A controlled current flow path between input and output terminals of the battery charger controller circuit is controlled to provide a substantially constant current to charge the battery to a nominal battery voltage. When a constant voltage output of the said adapter transitions to a value that limits available charging current to a value less than programmed constant charging current, current flow drive for the controlled current flow path is increased for a limited time interval. Thereafter, the controlled current flow path gradually reduces charging current as the battery voltage remains at its nominal battery voltage until the charge is complete or otherwise terminated.
