摘要： A circuit for heartbeat detection derives the heartbeat frquency from ultrasonic signals reflected from the heart and frequency-shifted due to the Doppler effect. The circuit allows for the automatic determination of the distance between the heart and an ultrasonic transducer located on the body of the patient, so that the evaluation of the reflected ultrasonic signals can be limited to a small body range and spurious signals from other ranges can be suppressed. The circuit comprises at least two channels which are enabled by a transmitting/receiving control circuit during receiving intervals for receiving and further processing the reflected ultrasonic signals. The receiving intervals of the different channels are time shifted toward one another so that the respectively received ultrasonic signals originate from different depth ranges within the body. A comparison circuit compares the strengths of the signals corresponding to the heartbeat during each heartbeat period in the individual channels, and thus derives a gradient which indicates the direction in which the receiving intervals or transmit windows are to be shifted during the subsequent heartbeat period in order to localize the heart.

摘要： A system and method for measuring the acoustically induced vibrations within a living organism. The object is ensonified to set it into low frequency vibration. A continuous wave beam of ultrasonic energy is transmitted along one path and focused at the tissue to be investigated. A focused transducer receives the reflected beam along a second axis such that the intersection of the transmitted and received beams define a small, concentrated region positioned at the object under investigation. The received beam is phase modulated by the amplitude of vibration of the object producing sidebands whose amplitude can be ratioed to the amplitude of the high frequency peak to determine the absolute amplitude of the low frequency vibration.

摘要： There is disclosed an automated flush system which senses the approach and departure of an object or person and produces control signals indicative of said approach and departure, respectively. A discriminator unit receives and decodes the approach and departure signals to produce a flush control signal which controls a flush valve in the flush system as a result of the occurrence of the departure signal following the occurrence of the approach signal.

摘要： An electronic apparatus for depth sounding and range finding and primarily intended for use with ships. The apparatus produces an analogue voltage indicative of distance and proportional to the time duration between the transmission of pulses of acoustic energy and the reception of corresponding reflection pulses and includes circuitry for producing warning signals if the analogue voltage reaches a pre-set value indicative of a certain distance or if the rate of change of the analogue voltage is predictable as producing a future value indicative of a certain distance within a pre-set time interval. Further circuitry is provided to improve the validity of the operational results of the apparatus.

摘要： Method and apparatus for scanning a plurality of channels to determine the azimuth of propagation of, and/or the Doppler shift in, acoustic waves which impinge on a receiver, where each channel carries a signal which is a different function of the azimuth or frequency, respectively, but where three or more of the signals are nonzero for the same value of azimuth or frequency. The method includes the steps of scanning the channels to obtain the nonzero signals in successive order, without interpolating to determine the azimuth or frequency, and then interpolating the azimuth or frequency from the nonzero signals.

摘要： The invention relates to a device with a microphone and a speaker or transducer and processing means to process audio signals from the microphone and for the transducer. Electronic devices and especially mobile devices serve several user interfaces of which the touch screen has revolutionized the market in the past few years. Ultrasonic gesture control has the power to add another interface that fills in for use cases where the touch screen is not reliable. This holds true for medical environments as well as for outdoor use cases just to name two. The invention suggests a different signal processing of the ultrasonic sending and receiving signals in order not to produce audible artefacts.

摘要： Sonar rendering systems and methods are described herein. One example is an apparatus that includes a transducer element, position sensing circuitry, processing circuitry, and a display device. The processing circuitry may be configured to receive raw sonar data and positioning data, convert the raw sonar data into range cell data based at least on amplitudes of the return echoes, make a location-based association between the raw sonar data and the positioning data, plot the range cell data based on respective positions derived from the positioning data and rotate the range cell data based on a direction of movement of the watercraft to generate adjusted range cell data. The processing circuitry may be further configured to convert the adjusted range cell data into sonar image data, and cause the display device to render the sonar image data with a presentation of a geographic map.
