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 capacitive humidity sensor includes a semiconductor substrate, a protective layer and a humidity sensitive section including a pair of comb electrodes and a humidity sensitive layer having a dielectric constant, which changes in accordance with humidity. The comb electrodes are disposed on one surface of the semiconductor substrate through the protective layer to face each other with a predetermined gap. An interface between the protective layer and the humidity sensitive layer is planarized so that the sensor prevents a hysteresis in a variation of capacitance. For example, a surface of the protective layer can be made flat by polishing.

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.
