摘要： A distance measuring apparatus measures a distance to a target from a plurality of directions, and includes sensors having identical two-dimensional scan type configurations that launch a laser beam and receive reflected light from the target by a multi-segment light receiving element, and a processor. The processor performs a process including specifying a receiving part of the multi-segment light receiving element of a first sensor, that receives a second laser beam launched from a second sensor in a state in which the target is non-detectable by the first sensor, adjusting a phase in a vertical scan direction of the second laser beam with respect to that of a first laser beam launched from the first sensor, until the receiving part no longer receives the second laser beam, and integrating range images from the first and second sensors after the phase is adjusted.

The device includes an ultrasound source for emitting an ultrasound transmission signal and an ultrasound receiver for receiving a corresponding ultrasound signal reflected by an obstacle, a control module for measuring a time of flight between emission of the ultrasound transmission signal and reception of the corresponding ultrasound signal reflected by the obstacle and calculating, on the basis of the aforesaid time of flight, the distance at which the obstacle is located. The device comprises an inertial sensor, in particular an acceleration sensor, designed to measure acceleration of the foot along three axes, and a control module configured for enabling operation of the ultrasound source if the aforesaid acceleration values measured by the inertial sensor respect a given condition for enabling measurement of the time of flight.

摘要： An ultrasound imaging system includes: a harmonic filter coupled to an ultrasound transmitter to reduce transmitted harmonic components; a fundamental filter coupled with an ultrasound receiver to reduce received fundamental components; and a fusion processor configured to generate multiple frames of fusion images for two subsequent frames of ultrasound transmissions to improve frame rate. The ultrasound receiver may optionally perform signal alignment and matching to improve image quality. To improve image quality, the ultrasound system may optionally use multiple amplitude-modulated transmit pulses with different delays, or multiple transmit pulses with different amplitudes to extract harmonic signals.
