Title: Low-power direct digital synthesizer
Inventor: SHIE SU-CHIN
IPC: H04B1/00
Filed: 2002-05-15
Granted: 2005-03-01
Abstract: A low-power direct digital synthesizer utilizes small amount of memories and a simple hardware circuit to generate a digital sine wave and cosine wave signals based on the phase signal outputted by a phase accumulator. Firstly, the simple hardware circuit is used to generate the estimated value of sinusoidal wave, then expand the difference between the correct value and the estimated value of sinusoidal wave at a specific phase by Taylor's series, store the zero-th order and first order coefficients in the memories, so as to generate the correction quantity of the estimated value, and correct the estimated value of the sinusoidal wave value for obtaining the correct value of sinusoidal wave. By the design method associating the correction of estimated value of sinusoidal wave and Taylor's series expansion, the circuit is simplified while the quality of accurate sinusoidal wave signal is ensured.

IPC: H04N5/335
Filed: 2002-06-12
Granted: 2003-12-01
Abstract: A high-speed event is imaged with an image sensor (a MOS type optical sensor circuit with a wide dynamic range for suppressing occurrence of an after image is used for each pixel unit). The data on the image produced by the image sensor is stored in a memory. In playing, the variation of each pixel output of the image sensor is corrected on the basis of the data on the image read out of the memory by a corrector. An image is displayed on a display on the basis of the corrected data. While storing data at a speed following up the high-speed event, the variation of each pixel output of the image sensor is corrected at a normal processing speed without following up the high speed.

Title: Schottky barrier diode and process
Inventor: ASANO TETSURO
IPC: H01L27/095
Filed: 2002-07-16
Granted: 2003-09-11
Abstract: This invention provides a novel Schottky barrier diode free from a mesa etching and a thick polyimide layer which hindered the size-reduction of chip in conventional art. The Schottky barrier diode also reduces the distance between electrodes and enhances the control of etching of Schottky junctions. The mesa and polyimide layer are eliminated by providing an n+ type ion implant region on the surface of the substrate, to form a planar type Schottky barrier diode containing a chemical compound semiconductor, wherein the distance between electrodes is reduced, the chip size is reduced, and the high frequency characterics are improved. The Schottky barrier diode of this invention provides an excellent repetitivity in production because no etching GaAs is performed when Schottky electrodes are formed.

Filed: 2003-05-28
Granted: 2007-09-11
Abstract: The present discloses a framework that allows a synchronization engine to synchronize data between a mobile device and Back End data stores independently from the architecture and data formats of that Back End data store. The framework introduces content adapters, which access synchronization data from backend data systems. These adapters convert the data into a Back End data store independent representation, which can be used by all applications or modules which need to access different back-ends in a generic manner. A generic synchronization engine for the purpose of conflict detection and resolution is one example for a module of this kind. Other applications that could use the content adapter are Notification Frameworks or Portals and all other applications aggregating data. Any Back End data store specific issues are handled by the Back End dependent part of content adapters, which can easi1y provided by third parties and plugged into the framework.
