摘要： Examples of systems and methods are provided for generating an output signal having an output code having less number of bits compared to an input signal having a thermometer code representation. The system may partition the input code bits into non-overlapping clusters. The system may generate a control signal for each of the clusters based on, at least in part, a logical OR operation over all bits in a corresponding one of the clusters. The system may determine a transition cluster comprising a 1/0 transition in the input code bits. The system may determine output code bits based on, at least in part, an input code bit pattern in the transition cluster and an identity of the transition cluster.

摘要： A circuit for transmitting and receiving communications. The circuit includes a transmit block, a receive block, and an echo canceller, coupled to the transmit block and to the receive block, for determining an echo signal and subtracting it from the received signal, the determination of the echo signal involving a predetermined number N of coefficients calculated at the beginning of each of the communications in an initialization phase. The circuit periodically updates during communication a restricted group of coefficients chosen from among the most significant coefficients. The present invention also relates to an echo cancellation method.

摘要： A device for identifying a determined repetitive sequence of predetermined signals arriving on a modem. The device includes a delay circuit so that all the words of a sequence are simultaneously present; a combination circuit for providing a combined word; a circuit for calculating the modulus of each combined word and for comparing this modulus with a threshold; a circuit for counting clock pulses corresponding to the rate at which words arrive; a circuit for inhibiting the counting circuit when the modulus of the combined word is lower than the threshold; and a circuit for providing an identification signal when a predetermined number of clock signals is counted.

摘要： A digital phase-locked loop filter in which the incoming error signals are subject to at least one multiplication by a filtering coefficient before being digitally processed at each clock pulse to provide a filtered signal. The PLL filter includes a circuit which decrements the value of the filtering coefficients at each clock pulse during an initial operation period of the filter.

摘要： A supplemental bumper apparatus for covering the bumper of a personal water craft and providing enhanced shock absorption and blemish resistance. The supplemental bumper apparatus comprises a synthetic rubber body and a fastener system. The synthetic rubber body provides a barrier which can absorb shock and block blemishes from an impact. The synthetic rubber body is attached to the bumper fastener system defined by a plurality of snap fasteners on its upper section and a hook and loop fabric fastener is on its lower section. A plurality of snap fastener base members are permanently attached to the bumper and a corresponding hook and loop fastener material is permanently attached to the bumper, each providing a corresponding engaging member to enable the snap fasteners and the hook and loop fastener surface to attach the synthetic rubber body to the surface of the bumper.

摘要： A muffler providing a compact and low-profile form factor for small two-stroke engines is described, particularly useful for aerodynamic radio controlled aircraft. The muffler comprises a tuned internal header eliminating the need for an external header to mount the inventive muffler to the exhaust port of a two-stroke engine while maintaining enhanced engine performance, obviating the need for a conventional tuned-pipe exhaust.
