摘要： A method and apparatus for moderating interference with impulse radio wireless control of an appliance; the control is effected by a controller remote from the appliance transmitting impulse radio digital control signals to the appliance. The control signals have a transmission power and a data rate. The method comprises the steps of: (a) in no particular order: (1) establishing a maximum acceptable noise value for a parameter relating to interfering signals; (2) establishing a frequency range for measuring the interfering signals; (b) measuring the parameter for the interference signals within the frequency range; and (c) when the parameter exceeds the maximum acceptable noise value, effecting an alteration of transmission of the control signals. The apparatus is for moderating interference with impulse radio wireless control of an appliance; the control being effected by a controller remote from the appliance, the controller transmitting impulse radio digital control signals to the appliance; the control signals having a transmission power and a data rate; the apparatus comprising: a threshold unit for establishing a maximum acceptable noise value for a parameter relating to interfering signals in a predetermined frequency range; and a measuring unit for measuring the parameter for the interference signals within the frequency range; and a transmission control unit for effecting alteration of the transmission of the control signals when the parameter exceeds the maximum acceptable noise value.

摘要： A system and a method for position determination by impulse radio using a first transceiver having a first clock providing a first reference signal and a second transceiver placed spaced from the first transceiver. The system determines the position of the second transceiver. The second transceiver has a second clock that provides a second reference signal. A first sequence of pulses are transmitted from the first transceiver. The first sequence of pulses are then received at the second transceiver and the second transceiver is then synchronized with the first sequence of pulses. A second sequence of pulses are transmitted from the second transceiver. The first transceiver receives the second sequence of pulses and the first transceiver is synchronized with the second sequence of pulses. A delayed first reference signal is generated in response to the synchronization with the second sequence of pulses. A time difference between the delayed first reference signal and the first reference signal is then measured. The time difference indicates a total time of flight of the first and second sequence of pulses. The distance between the first and the second transceiver is determined from the time difference. The direction of the second transceiver from the first transceiver is determined using a directional antenna. Finally, the position of the second transceiver is determined using the distance and the direction.

摘要： A system and method are provided that can detect any part of a multipath impulse radio signal. More specifically, the method compares a template pulse train and the multipath impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks onto any part of the multipath impulse radio signal including a direct path part and at least one multipath reflection part. The system may also perform a quick check, a sychronization check, and/or a command check of the multipath impulse radio signal.

摘要： An impulse radio concurrently receives an impulse signal and interference. An interference sampler samples the interference before an expected time of arrival of an impulse in the impulse signal, to produce an interference nulling sample. Then, when the impulse arrives, a data sampler samples the impulse in the presence of the interference to produce a data sample including undesired interference energy. The anticipatory nulling sample is an estimate of the undesired interference energy captured in the subsequent data sample so that the nulling sample can be used to cancel the interference energy from the data sample. When the nulling sample precedes the data sample by an odd number of half cycle periods of the interference, the nulling sample is additively combined with the data sample to derive a corrected data sample, from which a portion of the interference energy is canceled. When the nulling sample precedes the data sample by an even number of half cycle periods of the interference, the nulling sample is subtractively combined with the data sample to derive a corrected data sample.

摘要： Potential interference is reduced in an impulse radio. A signal including an impulse signal and potential interference is received by the impulse radio. The impulse signal includes a sequence of impulses. The sequence of impulses of the received signal is sampled at a sequence of data sample times to produce a sequence of data samples. The received signal is also sampled at a plurality of time offsets from each of the data sample times to produce a plurality of nulling samples corresponding to each of the data samples. A separate sequence of nulling samples for each of the time offsets is thereby produced. Each of the data samples is then separately combined with a corresponding nulling sample from each of the separate sequences of nulling samples to produce a separate sequence of adjusted samples corresponding to each of the time offsets. A separate quality metric, representative of a signal-to-interference level, is then determined for each of the separate sequences of adjusted samples. A preferred sequence of samples is selected for further signal processing based on the determined quality metrics. Alternatively or additionally, one of the plurality of time offsets is selected as the preferred time offset based on the determined quality metrics.

摘要： The present invention relates to a stepping motor with a magnet pole pattern having a predetermined pattern around the circumference of the stepping motor. In one embodiment, the pattern relates to a code having a unique single maximum autocorrelation peak over the period of the code. Example codes include Barker codes, PN codes, Kasami codes, Golomb ruler codes, and other codes. In one embodiment, the rotor and stator have a matching pole pattern. In one embodiment, the drive is arranged to align the poles in an inline configuration, alternatively, the drive may be arranged to align the poles in a diagonal configuration. In a further embodiment, one or more sets of poles are provided on the stator, each set being offset rotationally by a partial pole spacing. In one embodiment, the rotor is initially synchronized with the stator by capturing the rotor using a single unambiguous lock-in position based on the code autocorrelation.
