  • Patent number: 7859840
    Abstract: A portable heat dissipation device is provided for operation with various devices of different purposes for heat dissipation therefrom and includes an enclosure and an air flow generation device. The air flow generation device is set in a given chamber inside the enclosure to effect flowing of air, causing air to enter through an inlet opening defined in a top of the enclosure and forcing the air flowing out through an outlet opening defined in a front wall of the enclosure. The portable heat dissipation device, when applied to remove heat, provides high performance of heat dissipation and effectively extended time interval of operation to thereby extend the lifespan of the device.

  • Patent number: 7787636
    Abstract: 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.

  • Patent number: 7099497
    Abstract: 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.

  • Publication number: 20060049092
    Abstract: A membrane bioreactor includes a tank, a porous pre-filtering element mounted in the tank for conducting a primary filtration of wastewater, at least one membrane module mounted in the tank and disposed downstream of the porous pre-filtering element for conducting a secondary filtration of the wastewater, and a turbulent flow-forming unit. The membrane module cooperates with the porous pre-filtering element or another membrane module to define a compartment therebetween for receiving the wastewater pretreated by the porous pre-filtering element. The turbulent flow-forming unit is associated with the compartment for generating turbulent flow in the compartment.

  • Patent number: 6968503
    Abstract: 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.

  • Publication number: 20050200151
    Abstract: 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.

  • Publication number: 20040152427
    Abstract: 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.

  • Patent number: 6327637
    Abstract: 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.
