摘要： An acceleration sensor has a ring-shaped movable electrode connected to an anchor part via beams and a fixed electrode facing the ring-shaped movable electrode defining a specific interval, which are disposed on a substrate. The movable electrode is displaced by acceleration approximately in parallel to the substrate and contacts the fixed electrode, so that the acceleration is detected. The fixed electrode is divided into a detecting fixed electrode for contacting the movable electrode and a sensitivity controlling fixed electrode insulated from the detecting fixed electrode. Accordingly, potential differences between the movable electrode and the detecting fixed electrode and between the movable electrode and the sensitivity controlling fixed electrode are independently controlled to control sensitivity of acceleration.

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 collision detection device for a vehicle includes a first direction signal outputting unit which detects an intensity of heat ray radiated from a detection object which is near or contacts the vehicle to outputs a first direction signal, a second direction signal outputting unit which detects ultrasound wave sent by a sending member and reflected by the detection object to output a second direction signal, an impact signal outputting unit which detects an impact on the vehicle to output an impact signal, and a control unit. The control unit determines an occurrence of a collision between the vehicle and a human, in the case where it is determined that a difference between the first direction signal and the second direction signal is within a first predetermined range and the impact signal is outputted.

摘要： An ultrasonic sensor composed of a substrate and a piezoelectric vibrator mounted on the substrate is advantageously used as a sensor for detecting a distance to an object located in front of an automotive vehicle. Ultrasonic waves transmitted from the sensor are reflected by the object, and the reflected waves are received by the sensor. Based on the reflected waves, the distance from the vehicle to the object is calculated. To reduce rigidity and thereby to lower a resonant frequency of the substrate to a desirable level, grooves are formed in the substrate. A thickness of the substrate is not reduced to maintain its mechanical strength against an impact force. A resonant frequency which is desirable to realize a sufficiently high directivity and sensitivity is obtained in this manner without enlarging a size of the ultrasonic sensor.
