    摘要: A method of communicating data in a system having a plurality of transmitters each adapted to transmit a radio signal, and a receiver situated at a distance from the transmitters to receive and process the signals transmitted by the transmitters, information for transmission being subdivided into N-bit symbols, the method consisting in: giving a numerical value to each symbol; and compressing the data using a CHIP encoding technique in which the values of the symbols are transposed to an encoded value having x digits in a base B, each digit subsequently being represented in the form of n chips, the base B, the number n of chips, and the number x of digits for an encoded value satisfying the following conditions: B≦2&ngr; and 2N≦B&xgr;  so that the total number of chips x.n representing the coded value is less than 2.N.

    摘要: This method which enables two periodic signals having the same waveform and the same theoretical period to be synchronized is of the type in which the second signal is synthesized iteratively at a phase that is adjusted as a function of a measure of the correlation between the first and second signals. Synchronization is obtained by progressively shifting the phase of the second signal until a correlation maximum is detected, after which said signal is locked onto the correlation peak by phase skips on either side thereof.

    摘要: A rear suspension system for a two wheel cycle such as a bicycle or motorcycle having a main frame which includes a rearwardly or downwardly inclined down tube. A vertically pivotable rear frame assembly includes a pair of swing arms which extend rearwardly from pivotal connections on the main frame. Rear wheel fitments are carried by the swing arms. A pair of elongated tubelike or rodlike chain stays extend forwardly from the rear fitments at a fixed angle relative to the swing arms. A tubular shock absorber assembly is supported on the down tube and has a spring urging a coupler portion thereof in a forward and upward direction. A double-pivoted link is pivotally connected between the forward ends of the chain stays and a bell crank assembly which is pivotally connected to the underside of the frame, and in turn, connects the double-pivoted link to the coupler portion of the shock absorber assembly. Upward impacts on the rear wheel are reacted on the main frame as a downward and rearward force with a largely downward force component so pitching motion at the rear end of the main frame is minimized when moving over ground or highway irregularities or rough terrain encountered in off road riding. In one embodiment, the shock absorber assembly is supported on the forward side of the down tube; in another embodiment, the shock absorber assembly is inside an open-rear-ended down tube.
