    摘要： The present invention is designed to be fitted in the upper part of Roll Bars on small vehicles such as quad bikes, ATV's, ride-on mowers, and small tractors (“small vehicles”) to overcome the issue with striking overhanging objects. If the Roll Bar system including the present invention is struck when the vehicle is in forward motion, the present invention allows the upper portion of the Roll Bar to flex, either allowing it to pass under the object or providing a more gradual reduction in speed as opposed to an instant jolt, then returning to the original upright position.

    摘要： Methods and apparatus for tuning are disclosed. One embodiment of the invention is directed to a tuner formed on a substrate. The tuner comprises a first die that receives an analog input signal and processes the analog input signal using analog processing circuitry to form analog output signals, and a second die that receives the analog output signals, converts the analog output signals to digital signals, and processes the digital signals to form output signals. Another embodiment of the invention is directed to a multi-chip module comprising a tuner adapted to process television signals of a plurality of types and of a plurality of standards to form output signals. A further embodiment of the invention is directed to a method that comprises receiving an analog signal from a signal source, filtering the analog signal to remove a portion of the analog signal, converting the analog signal to quadrature analog signals, converting the quadrature analog signals to digital signals, and filtering the digital signals to substantially isolate a channel of interest.

    摘要： The invention relates to a suturing instrument for performing a surgical procedure, such as passing a suture through tissue, and methods thereof. The suturing instrument is a low profile device that includes an elongate body member, a needle exit port, a needle catch, and a needle deployment mechanism. The needle deployment mechanism drives the needle distally between the needle exit port and the needle catch.

    摘要： A combined nozzle set and lift tool is provided for use with a pop-up sprinkler, wherein the lift tool comprises a tool body in the form of an injection molded runner formed integrally with a plurality of individual nozzle inserts. An elongated tool stem projects outwardly from the tool body and has protruding tabs at a tip end thereof for reception into an undercut recess formed in a pop-up sprinkler spray head to permit lifting of the spray head from a normal position spring-retracted substantially within a sprinkler housing or case, to an elevated position for facilitated access to the spray head. A selected one of the plurality of nozzle inserts can be separated from the lift tool as by snap-off detachment, whereupon the selected nozzle insert can be mounted on the elevated spray head to individually tailor the characteristics of a water stream projected therefrom during normal sprinkler operation. The lift tool further includes latch teeth for snap-fit engagement with the spray head to permit storage of the combined nozzle set and lift tool on the spray head, to provide a convenient commercial unit which can be transported to an installation site with little or no risk of components becoming lost or misplaced.

    摘要： Improved data scramblers and swapper cells and improved digital to analog converters are provided. The improved swapper cells permit data to be propagated through the cell immediately upon receipt. The determination of whether to swap data or pass it directly through is based on a history of data values propagated through the cell, but is independent of the values of the particular inputs being swapped. The data scrambler is structured to permit the possible data inputs on swapper cells in the scrambler to be restricted. A minimum delay data scrambler for use in a fast digital to analog converter is disclosed using these components.
