    摘要： The present invention relates to a vector sensor for measuring particle movement in a medium. The vector sensor comprises a magnetic body that is held at a certain distance from a magnetometer in such a way that the magnetic body can move in time with a passing particle movement, wherein the magnetometer is arranged to detect the oscillations in the magnetic field that the movements in the medium produce.

    摘要： Systems, methods, and devices may enhance the apparent sample rate of data collected using Nyquist sampling from a system, such as Continuous Wave (CW) Light detection and ranging (“Lidar”), Radio detection and ranging (“Radar”), or Sound Navigation and Ranging (“Sonar”), that has been modulated with a repeating waveform, such as linear swept frequency, by reordering of the data in the frequency domain. The enhancement of the apparent sample rate may result in a highly interpolated range profile where the data resolution may be enhanced by a factor equal to the number of repeats in the signal being processed, and may result in a highly detained range measurement with a high precision. The various embodiments may combine data from multiple modulation repeats into a single highly interpolated pulse, which may result in a real-time finer range measurement from CW Lidar, Radar, or Sonar systems.

    摘要： An apparatus comprises a test signal generator (401) which generates an ultrasonic test signal by modulating an audio band test signal on an ultrasonic signal. The ultrasonic test signal is radiated from a parametric loudspeaker (403) and is demodulated by non-linearities in the air. A reflected audio signal may arise from reflections of an object, such as a wall. An audio band sensor (405) generates an audio band captured signal which comprises the demodulated reflected audio band signal. A distance circuit (407) then generates a distance estimate for the distance from the parametric loudspeaker (403) to the object in response to a comparison of the audio band captured signal and the audio band test signal. Specifically two signals may be correlated to determine a delay corresponding to the full path length. Based on the distance estimates an audio environment may be estimated and a sound system may be adapted accordingly.

    摘要： A moving object detecting apparatus includes: a transmitting/receiving unit for radiating an ultrasonic wave and receiving a reflective wave reflected from an object present in a monitoring space; a phase detection circuit for mixing reference signals with a reflective signal and obtaining a pair of Doppler signals each having an amplitude depending on a phase difference from the reference signal, each of the Doppler signals having a different phase from each other; a rotation angle calculation unit for calculating a rotation angle; a cumulative addition unit for accumulating the rotation angle; and a comparison unit for comparing the accumulated rotation angle with a threshold value. In the moving object detecting apparatus, a single ultrasonic vibrator is commonly used in the transmitting unit and the receiving unit.

    摘要： The invention provides a sonar system having a moving window display of the sonified area in which a single broad beam projecting transducer is employed to sonify a desired area. A plurality of line focus receiving transducers are used to receive signals from adjacent strips of the sonified area, and the signals received from each transducer are amplified, detected and sampled. A sampling switch is employed to sequentially sample each detector channel RE times, where RE represents the number of range elements. The sampled signals are then stored in a magnetic storage device, preferably a magnetic disc. The signals from a single sonar pulse are stored in groups, equal in number to the number of receiving transducers, at nonadjacent locations on the disc track, and the signals corresponding to equal range elements from previous and subsequent pulses are stored at adjacent locations in the order received. The disc rotates 360* + OR phi during one picture interval to provide the moving picture display on a cathode ray tube electrically connected to a read head on the magnetic storage means.
