摘要： An ultrasonic sensor includes a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object. The threshold adjustment section reduces the first threshold, when the output voltage corresponding to the calculated sound pressure is less than a second threshold that is greater the first threshold.

摘要： A laser sensor is located close to a rotation axis of a vehicle door and configured to emit a laser beam to a surface of the vehicle door and accept reflected light reflected from an obstacle for scanning a scanning plane shifted in a door-opening direction, in which the vehicle door is openable. A determination section determines whether an obstacle, which is possible to make contact with the vehicle door, exists in the door-opening direction of the vehicle door, based on a result of emission and acceptance of the laser beam of the laser sensor. An opening regulating section regulates an opening of the vehicle door in response to determination of the determination section that the obstacle exists.

摘要： An ultrasonic sensor is disclosed. The ultrasonic sensor includes a piezoelectric element and an acoustic matching member. The piezoelectric element is configured to detect ultrasonic wave transmitted from a transmitter and reflected by a detection target object located in a detection target space. The acoustic matching member is configured to conduct the received ultrasonic wave to the piezoelectric element. The piezo electric element is covered with the acoustic matching member including a principal oscillation portion and a supplement oscillation portion. Thickness of a part of the supplement oscillation portion, the part covering the piezoelectric element, is smaller than a predetermined thickness threshold.

摘要： In an obstacle detection system, a wave transmitted by a transmitting element and received by receiving elements as a receiving wave includes extraneous waves, which are reflection waves from other than an obstacle, and obstacle reflection waves from an obstacle. It is determined that, an obstacle is present, if the reflection waves are detected as having an amplitude (voltage) greater than a threshold level and a reception time difference between time points at which the amplitude exceeds threshold level at the receiving elements is less than a predetermined time.
