Abstract:
A chip array structure for laser diodes, formed on an active surface of a semiconductor chip produced from a semiconductor process includes a plurality of light-emitting elements in an array arrangement, at least one insulation wall, at least two wire bond areas and a plurality of connection electrodes. The insulation wall separates the light-emitting elements into at least two light-emitting districts. The wire bond areas are positioned respective to the corresponding light-emitting districts. The connection electrodes electrically couple the wire bond areas with the corresponding light-emitting districts. The wire bond areas have independent electrodes, and the light-emitting districts are electrically isolated by the insulation wall.

Abstract:
A three-dimensional connector, which is used by a coordinate input device of a touch pad, has a flat conductor cable with an end being connected to the touch pad and another end forming a soldered conductive contact head perpendicular to the flat conductor cable to pass through a support to shorten a length of said conductor cable and enhance electro-conductibility of the connector.
Abstract:
A method and system of controlling halt and resumption of scanning actions of an LCD is disclosed. An incoming video source is monitored, and current scan line position and corresponding polarity are recorded. When an abnormal video source is detected, the LCD scanning is stopped at a halt scan line of a halt frame with a halt polarity. After a normal video source has been detected again, determination is made of a proper resumptive scan line and/or a resumptive polarity. The panel scanning is resumed at the resumptive scan line equal to the halt scan line and/or with the resumptive polarity matching the halt polarity.

A method for generating a one-time password (OTP) by using software only is provided. The method is suitable for generating a common dynamic password in a first electronic device and a second electronic device. First, an initial number is provided to the first electronic device and the second electronic devices. Then, a value is generated, encrypted into a transmission value according to the initial number, and transmitted to the second electronic device by the first electronic device. Next, the transmission value is decrypted by the second electronic device according to the initial number to obtain the value. Finally, a dynamic password is respectively generated in the first electronic device and the second electronic device according to the initial number and the value. Thereby, an OTP system is constituted.
Abstract:
In a method and apparatus for enabling fast clock phase locking in a phase-locked loop, a sampling clock generator generates sampling clock signals in response to an oscillator output of the phase-locked loop. A detector unit samples an input digital signal to the phase-locked loop at clock edges of the sampling clock signals to obtain multiple sampling points of the input digital signal, and compares logic levels of each temporally adjacent pair of the sampling points to detect presence of a logic level transition in the input digital signal. A selector unit is controlled by the detector unit to select one of the sampling clock signals, which has one of the clock edges thereof defining an interval that was detected to have occurrence of the logic level transition in the input digital signal, and which is subsequently provided to the phase-locked loop as an input phase-locking clock signal.

Abstract:
The present invention describes an apparatus and method for optical disk drive signal processing. For improving the bandwidth for signal transmitting between an optical disk drive (ODD) controller and an optical pick-up unit (OPU) via a flexible cable, a physical address pre-processing unit is mounted on the optical pick-up unit of a Optical disk drive. The long settling time problem conventionally due to a voltage change in the writing process can be resolved. The apparatus and method extract the physical address in the high-writing process of the Optical disk drive.
Abstract:
A semiconductor memory device with a function of equalizing voltages of dataline pair. After turning off the word line and before turning on the equalization means, the datalines are precharged and discharged to a supplied voltage and ground, respectively. Using the theory of uniform distribution of charges, the datalines are equalized into VCC/2, that is, a half of the source supply voltage. The interference on a weak voltage VCC/2 generator within the equalization means during the equalization mode is thus avoided. The equalization of voltages on the dataline pair can be achieved within a transient cycle. Complete data can thus be written or read before the next command is given.
