Abstract: A plurality of ultrasonic sensors are configured such that search ultrasonic waves transmitted from the respective ultrasonic sensors have mutually different characteristics that are mutually distinguishable. A transmission timing setting unit is configured to set a transmission timing of transmitting the search ultrasonic wave for each of the ultrasonic sensors, such that the plurality of ultrasonic sensors transmit the respective search ultrasonic waves at respective transmission timings that are mutually different. The transmission timing setting unit is configured to set a delay time between a first transmission timing, which is a transmission timing of the first ultrasonic sensor, and a second transmission timing, which is a transmission timing of the second ultrasonic sensor, with the delay time being determined based on a positional relationship between the first ultrasonic sensor and the second ultrasonic sensor.

Abstract: A transducer assembly comprises a housing and a plurality of frequency steered transducer array elements. Each of the transducer array elements includes a plurality of piezoelectric elements. The frequency steered transducer array elements are configured to receive a transmit electronic signal including a plurality of frequency components and to transmit an array of sonar beams into a body of water. Each sonar beam is transmitted in an angular direction that varies according to one of the frequency components of the transmit electronic signal. The frequency steered transducer array elements are positioned within the housing in a fan-shaped configuration where an end section of at least two of the frequency steered transducer array elements are within an intersection range of each other.

Abstract: A dual-band ultrasonic sensing apparatus for vehicles and a control method thereof. The dual-band ultrasonic sensing apparatus includes a first waveform transceiver configured to transmit and receive ultrasound in a first center frequency band, a second waveform transceiver configured to transmit and receive ultrasound in a second center frequency band higher than the first center frequency band, a processor configured to sequentially transmit and receive ultrasonic waves through the first and second waveform transceivers, to calculate each distance based on the result of transmission and reception by compensating for signal attenuation due to a difference in center frequency, and to calculate a final distance by determining whether to detect an obstacle through each calculated distance, and an output unit configured to output the final distance calculated by the processor.

Abstract: A collision prevention device is mounted on a vehicle and prevents collision against an obstacle by controlling a driving system of the vehicle. This collision prevention device includes an obstacle sensor, an obstacle detection area setting unit, a detector and a vehicle controller. The obstacle sensor transmits one of a light wave, a radio wave and an ultrasonic wave to a predetermined obstacle detection area, and receives a reflected wave of one of the light wave, the radio wave and the ultrasonic wave. The obstacle detection area setting unit sets the obstacle detection area of the obstacle sensor. The detector detects the obstacle in the obstacle detection area based on a detection result of the obstacle sensor. The vehicle controller controls the driving system of the vehicle based on a result of the detection of the detector, and according to the obstacle detection area set by the obstacle detection area setting unit.

Abstract: A pedestrian detection device on a vehicle having a vehicular camera and a sonar or a radar includes: an identification dictionary storage unit that stores multiple identification dictionaries of shape features of a pedestrian; a detection result accumulation unit that searches the captured image for one feature to detect the pedestrian, and accumulates a detection result for each identification dictionary; a pedestrian position accumulation unit that detects the pedestrian using the sonar or the radar, and accumulates a pedestrian position; an identification dictionary selection unit that selects a detection identification dictionary having the detection result consistent with the pedestrian position; and a pedestrian detection unit that searches the captured image for one feature described in the detection identification dictionary, and detects the pedestrian.

Abstract: A weighing apparatus includes —a sample holder (20), —a protective housing (14, 16, 18) with an access port (181) and a closure element (26), —a reflection sensor (34) with a radiation emitter (37) emitting sensor radiation (38) reflected by a reflecting object (39) and with a radiation receiver (42) receiving a sensor radiation component (40), reflected by the object and —a control unit (32), connected to a motorized drive (30) of the closure element and to the reflection sensor, and which controls the motorized drive with a reflection sensor signal, for transferring the closure element between closed and open positions. A differentiating element subjects a sensor primary signal (52) of the reflection sensor to a differentiation. The primary signal depends on a reflection intensity of the reflected radiation component and generates a sensor secondary signal (60). The control unit controls the motorized drive based on the sign of the secondary signal.

Abstract: An obstacle monitoring system includes a first transducer that obtains a first distance measurement to an obstacle using a first linear frequency modulated (“LFM”) chirp. The system further includes a second transducer, able to operate concurrently with the first transducer, that obtains a second distance measurement to the obstacle using a second LFM chirp. The second LFM chirp has an inverted slope or shifted center frequency compared to the first LFM chirp. The system further includes a controller that processes the first and second distance measurements to determine a motion-compensated distance measurement to the obstacle.

Abstract: A miniature rangefinder includes a housing, a micromachined ultrasonic transducer, and signal processing circuitry. The housing includes a substrate and a lid. The housing has one or more apertures and the micromachined ultrasonic transducer is mounted over an aperture. The micromachined ultrasonic transducer may function as both a transmitter and a receiver. An integrated circuit is configured to drive the transducer to transmit an acoustic signal, detect a return signal, and determine a time of flight between emitting the acoustic signal and detecting the return signal.
