  • Publication number: 20070217169
    Abstract: A clamshell housing is used in a stand-alone configuration of “DualPlay” instrument modules. The housing comprises first and second sections pivotally connected by a hinge mechanism at a hinge end of the clamshell housing that allows rotation of the first and second sections relative to one other between an open and closed position. An open end of the clamshell housing is opposite to the hinge end. A sliding-fastener bumper section slides over the open end and secures the sections in the closed position. A main storage compartment is formed by the first and second sections when in the closed position and serves to hold the instrument module.

  • Publication number: 20070120588
    Abstract: A first oscillatory signal is distributed to a number of destinations in an integrated circuit die. The frequency of a second oscillatory signal is made to track the average frequency of the first oscillatory signal, using an injection locked oscillator, as such rejecting high frequency jitter. The second oscillatory signal is provided to one or more of the destinations. Other embodiments are also described and claimed.

  • Publication number: 20060288244
    Abstract: A processor having asymmetric secondary processing resources. One disclosed embodiment includes a first execution resource to perform a first function and a second execution resource that also performs the second function, although the second processing resource is asymmetric to the first resource in that it has a lower throughput than the first processing resource. Switching logic switches execution from the first processing resource to the second processing resource in a reduced power consumption mode.

  • Publication number: 20060202385
    Abstract: A master mould is made by wire cutting a plate in two or more directions to provide a base with an array of master mould needles protruding therefrom. The size and shape of the master mould needles can readily be varied by varying the angles of upward and downward cuts in the two or more directions. The master mould is used to make a secondary mould by hot embossing a secondary mould plate onto the master mould. This forms through-holes in the secondary mould. The secondary mould is plated with a layer of metal, which forms a microneedle array.

  • Publication number: 20060091964
    Abstract: A method and apparatus for jitter reduction in a Phase Locked Loop (PLL) that includes determining a size of a original charge pump adequate to generate an appropriate control voltage to a Voltage Controlled Oscillator (VCO) of a PLL based on the charge pump receiving a single up signal or down signal within one cycle of a PLL input reference clock. N number of the up signal or down signal are generated to a second charge pump 1/N the size of the original charge pump. The N number of the up signal or the down signal occurs within one cycle of the PLL input reference clock. The second charge pump generates N second control voltage corrections each being 1/N the amplitude of the appropriate control voltage glitch, thus minimizing glitches on the second control voltages and reducing jitter to the VCO.

  • Publication number: 20060060762
    Abstract: An electronic device having a first piece, a second piece moveable with respect to the first piece, and a position sensor operable to sense the position of the second piece relative to the first piece. The electronic device is operated in a first mode or a second mode dependent upon the position of the second piece relative to the first piece. Optionally, a proximity sensor is provided to detect the presence of a body in close proximity to the device when the second piece is in an open position relative to the first piece.

  • Publication number: 20050287954
    Abstract: A system and method directed to testing various communication signals and related components in a communications network. In one embodiment of the invention, a first set of data about a signal is collected when the signal is at an origin point in the communications network. Further, a second set of data about the signal is collected when the signal is at a destination point in the communications network. These two snapshots of the signal in the system can then be analyzed to determine a quality measurement based on a comparison of the first set of data and the second set of data. With such a testing method and system, various signals throughout a communications network can be tested at analyzed at any point n the system and trouble spots or high traffic areas in the communications network can be identified more quickly.
