摘要： A wireless remote control system is provided. This system includes a remote controller, plural detectors, and a decision module. The detectors are used for detecting the frequency a wireless signal emitted by the remote controller and respectively generate a detecting result. Based on at least one frequency difference between the detecting results, the decision module determines how the remote controller is moving and thereby generates a control signal. Because the decision module needs no knowledge of the frequency of the emitted wireless signal, the wireless remote controller has the advantages of small size, low cost, and low power consumption.

摘要： The invention relates to a method for locating a sound projecting target by means of an elongated underwater antenna (10) having a plurality of electroacoustic converters (11), wherein a horizontal target location (ßzk) is determined in the water as the target in a directionally selective manner from the receiving signals of the converters (11), including a measured variable (Cmess) of the acoustic velocity. In order to compensate the systematic location error inherent in such an underwater antenna, which may lead to erroneous locations particularly in the case of greater locating angles, the acoustic radiation course is calculated in the acoustic distribution direction specified by the target location (ßzk) by means of an acoustic distribution model, and a vertical acoustic incident angle (γk) is determined at the location of the antenna from the acoustic radiation course for an estimated distance and depth of the target. A correction factor is deduced from the vertical acoustic incident angle (Yk), and the measured variable (Cmess) of the acoustic velocity is corrected by multiplying the measured variable by said acoustic incident angle. Locating in turn is carried out using the corrected variable (Ceinstell) of the acoustic velocity, and an improved target location (ßzk) is obtained.

摘要： A zone location system with ultrasound US transmitters S1, S2, S3 located in respective zones Z1, Z2, Z3 such as rooms of a building B. Preferably, the US transmitters are time-multiplexed so that each of them in turn transmits a US signal US with a unique ID code USID represented therein. The portable tag PT includes an ultrasound receiver USR arranged to receive the US signal. Based on the received US signal, the portable tag PT measures a strength of the received US signal. The portable tag PT also measures a parameter related to a movement of the portable tag PT, e.g. a Doppler shift based on the received US signal. Further, the portable tag extracts the USID. Then it transmits a wireless Radio Frequency signal RFS with its own ID PTID, the USID and first and second data values D1, D2 representing the signal strength and the movement related parameters. A processor P connected to a Radio Frequency receiver RFR receives the data from the portable tag PT and determines a connection between PTID and the zone Z2 in which it is present based on the USID. Further, the processor utilizes data D1 and D2 to calculate an estimated position POS within the zone Z2. Especially, estimated distance between US transmitter S2 and portable tag PT and velocity of the portable tag may be estimated based on D1 and D2, thus assisting in estimating the position POS of the portable tag PT. The system may further be combined with a Radio Frequency based positioning system, e.g. an RF signal strength based system, thereby enhancing the resolution of the estimated position POS of the portable tag PT. Further, such combined system help location in complicated and changing environments and in situations where the portable tag PT may be out of reach for US signals, e.g. when attached to a paper file enclosed in a box.

摘要： A method and apparatus for tracking variations in distance D calculated from time-of-flight measurements of a sequence of pulses of a pressure wave oscillation from a transmitter to a receiver identifies a state of synchronous operation by obtaining at least two time-of-flight measurements (20, 22) derived from successive pressure wave pulses which satisfy given synchronicity criteria. Successive time-of-flight measurements are then monitored to identify a shifted time-of-flight measurement (26) which varies by at least half of the wave period from a preceding time-of-flight measurements. The distance D calculated from the shifted time-of-flight measurement is then corrected by the product of the shift factor and the pressure wave wavelength.
