  • Publication number: 20080123726
    Abstract: The invention proposes a simple method suitable for automatically locking frequency during USB data communication. Based on the soft plug/unplug concept proposed in the contents and the error handling mechanism defined in the USB specification, we can calibrate the clock frequency of the digitally controlled oscillator (DCO), through the token packets, to be within the acceptable frequency when USB device is attached to the host controller.

  • Publication number: 20080100388
    Abstract: A frequency-locking device including a digitally-controlled oscillator (DCO) and a comparing unit is disclosed. The DCO is used for generating an output frequency signal. The comparing unit receives a Keep Alive signal from a universal serial bus (USB) and the output frequency signal, and compares the Keep Alive signal with the output frequency signal to generate a calibration signal. Then, the DCO adjusts the frequency of the output frequency signal according to the calibration signal to meet the USB specification for data communication.

  • Publication number: 20060020234
    Abstract: An absorbent sac wound dressing comprising a wound-contacting layer covered with tapered pores and the bottom surface of tapered pores contacting a wound area wherein discharged exudate penetrates through, a guiding layer transmitting discharged exudate to an absorbent layer, an absorbent layer absorbing discharged exudate to make fibers expand into the shape of gel, which is effective in preventing from backflow of exudate to a wound area, and a translucent breathing layer having a broad spread of micro pores. The placement of the above layer is one on top of another in order and the peripheral edges are joined together by heat-sealing to form a sac without side escape. More particularly, the certain concentration of water-soluble antimicrobial medicines, enzymes or growth factor agents in a suitable amount are well distributed added in the absorbent layer, which is more effective in controlling a wound infection.

  • Patent number: 6594809
    Abstract: Antenna diodes used to correct antenna rule violations during the design and formation of integrated circuits are defined within filler cells laid out on the IC chip following the layout of standard electronic module cells and routing of electrical conductors on the chip. The filler cells are disposed in gaps between standard cells containing the electronic modules. The diodes are formed in unconnected pairs that are selectively connected to each other and to an adjacent conductor in order to correct antenna rule violations. Low current leakage is achieved as a result of the use of a fewer number of diode circuits, and the fact that they remain unconnected until used to correct an antenna rule violation.

  • Patent number: 6034552
    Abstract: A dynamic-floating-gate arrangement is used to improve the ESD robustness of driving-current-programmable CMOS output buffers in cell libraries, by suitably dynamically floating the gates of the NMOS/PMOS buffers using a small-dimension CMOS device having its drain connected to the gate of an unused CMOS buffer, its source connected to one of two voltage sources, and its gate connected between a resistance, that is connected between the two voltage sources, and a capacitance connected between the resistance and the same one of the two voltage sources as the source of the small-dimension CMOS device.

  • Patent number: 5977809
    Abstract: A programmable non-overlap clock generator is disclosed. This clock generator includes a primary clock signal input terminal for providing a primary clock signal, and a selection signal input terminal for providing at least one selection signal. The present invention also includes a first logic gate, whose first input terminal is coupled to receive an inverted signal of the primary clock signal. Further, the first input terminal of a second logic gate is coupled to receive the primary clock signal. A first programmable delay means, connected between an output of the first logic gate and the second input terminal of the second logic gate, is used to delay an output signal from the first logic gate a predetermined amount of time according to the selection signal.
