Patent number: 7787636Abstract: A sound recording device includes a disk drive, a microphone, and a controller. The disk drive writes data on a rotatable data storage disk therein. The microphone generates a microphone signal which includes a desired sound component and a noise component from noise that is generated by the disk drive. The controller filters the microphone signal to reduce the noise component from the disk drive relative to the desired sound component, and writes the filtered microphone signal on the disk. Accordingly, noise from the disk drive can be attenuated during recording by the sound recording device.Type: GrantFiled: February 6, 2006Date of Patent: August 31, 2010Assignee: Seagate Technology, LLCInventors: Liu Yanning, Ben Chang, Babu Rahman, Timothy Glassburn, Erhard Schreck

Patent number: 7099497Abstract: A capacitive fingerprint sensor includes a plurality of capacitive sensing members arranged in a 2D array. A charge-sharing principle is utilized to read signals in the capacitive sensing member. Each capacitive sensing member includes an insulating surface layer, a sense electrode, a reference electrode, a reference capacitor, and a signal reading circuit. The sense electrode is below the insulating surface layer. When a finger contacts the insulating surface layer, a sense capacitor is formed therebetween. The reference capacitor is connected between the reference and sense electrodes. The signal reading circuit is connected to the sense and reference electrodes, repeatedly provides control signals to charge the reference capacitor and then enable the reference and sense capacitor to share charges. Finally, the sense voltage of the sense electrode may be read.Type: GrantFiled: April 1, 2003Date of Patent: August 29, 2006Assignee: LighTuning Tech. Inc.Inventors: Bruce C. S.

Patent number: 6968503Abstract: A workflow server system is provided which uses an XML namespace designed to execute various workflow server services. The workflow server may include an XML Execution Engine, which uses the XML namespace to execute commands issued by the user from a web browser. The use of the XML namespace allows users to easily modify the user interface and how content is handled without needing to contact the manufacturer of the workflow server or engage in a massive redesign of the server. The Workflow Server passes a user command to an XML Execution Engine, accesses an XML namespace to determine how to execute said command, executes said command, accessing a database if necessary, and returns an XML document back to user for display on the user's web browser, said XML document containing a reference to an XSL file.Type: GrantFiled: March 9, 2000Date of Patent: November 22, 2005Assignee: Quovadx, Inc.Inventors: Tipin Ben Chang, Chung Jen Ho

Publication number: 20050200151Abstract: A rear seat assembly movable between a use configuration and a stowed configuration within a passenger compartment of a motor vehicle. The rear seat assembly includes a seat cushion having a front portion and a rear portion, a seat back disposed adjacent to the rear portion of the seat cushion, and a translator coupled to the seat back. The translator moves the seat back between the use configuration and the stowed configuration in which the seat back is adjacent to a rear lift gate of the motor vehicle.Type: ApplicationFiled: May 11, 2005Publication date: September 15, 2005Inventors: Christopher Welch, Ben Chang, Colin Neale

Publication number: 20040152427Abstract: A single crystal oscillator RF transmitter system converts a data to be transmitted into RF packets by a converter under the control of a microprocessor, receives the RF packets and generates an RF signal accordingly to be sent out by a transmitter. The system comprises a local oscillator to generate a first clock in response to an external crystal to provide for the transmitter and connected to a clock switch which divides the frequency of the first clock so as to generate a second clock to the microprocessor and a third clock to the converter. Alternatively, an RC oscillator generates a fourth clock for the clock switch to provide the second and third clocks for the microprocessor and converter, respectively.Type: ApplicationFiled: January 22, 2004Publication date: August 5, 2004Inventors: Yen-Chang Chiu, Chong-Hao Tang, Ki-Dar Lin, Ben-Chang Sun

Patent number: 6327637Abstract: Logic for a 1394-enabled system is disclosed which enables multiple internal link layers, connected to corresponding 1394 devices, to communicate with each other without an intervening physical layer, thereby eliminating one or more PHY chips and associated PHY-PHY cables and connectors (reducing both cost and power consumption). Using a single, optional PHY chip or the integrated PHY block, the internal devices can also communicate with external 1394 devices. The logic can also include, among other elements: multi-node logic to permit data to be transmitted between a device on an external 1394 bus and a selected one of two or more internal link layers; packet overlap logic to permit data to be transmitted between two internal link layers while data is being transmitted on an external 1394 bus; and a PHY-emulation module to provide each internal link layer with a corresponding “virtual” PHY layer having a node ID which is unique on an external 1394 bus.Type: GrantFiled: December 18, 1998Date of Patent: December 4, 2001Assignee: Cirrus Logic, Inc.Inventor: Ben Chang
