摘要： In a receiver circuit, a binary signal is generated based on a signal level of a received signal that has been received via a transmission line from a driver of a transmitter circuit. Then, a first stable state and a second stable state are detected based on a reference signal whose signal level changes in accordance with the received signal. In the first stable state, the received signal is stable at a first signal level. In the second stable state, the received signal is stable at a second signal level. When the first stable state is detected and the received signal is changed from the first signal level into the second signal level, the generated binary signal is retained at a signal level corresponding to the second signal level, until the second stable state is detected.

摘要： A capacitance type sensor includes a detection electrode, a reference electrode, and a sub-reference electrode for distinguishingly detecting a detection object. The sub-reference electrode has a reference voltage applied thereto and is displaceable relative to the detection electrode due to a pressure exerted from the detection object. A voltage application device applies a detection voltage to form an electric field in a space defined with the reference electrode device. A capacitance detector of the sensor detects a first capacitance and a second capacitance, and a detection unit of the sensor distinguishingly detects the detection object based on the first capacitance and the second capacitance. The first capacitance is measured between the detection electrode and the reference electrode, and the second capacitance is measured between the detection electrode and the sub-reference electrode.

摘要： An ultrasonic transducer includes a transducer case and an ultrasonic element. The transducer case is formed into a bottomed, cylindrical shape having a side plate portion and a bottom plate portion that seals one end side of the side plate portion in an axial direction to configure a diaphragm. The ultrasonic element is fixedly supported to the bottom plate portion to face an interior space surrounded by the side plate portion and the bottom plate portion. The ultrasonic element is arranged in a position being offset in an in-plane direction orthogonal to the axial direction relative to a center position of the diaphragm in the in-plane direction to be capable of generating a first transmission wave having first directivity characteristics and a second transmission wave having second directivity characteristics that are directivity characteristics differing from the first directivity characteristics and in which sound pressure in the axial direction is decreased.

摘要： An object detection device that detects a corner of an object includes: a transmitter that transmits a search wave; receivers that receive a reflected wave reflected off the corner. The device determines a first path length of the search wave from the transmitter to a first receiver, and uses the positions of the transmitter and the first receiver as focal points to find a first ellipse whose distances from the transmitter and the first receiver add up to the first path length. The device determines a second path length of the search wave from the transmitter to a second receiver, and uses the positions of the transmitter and the second receiver as focal points to find a second ellipse whose distances from the transmitter and the second receiver add up to the second path length. The device finds an intersection point between the first and second ellipses as the corner.

The sensor body includes a main electrode and a parallel electrode. The parallel electrode is disposed in parallel with the main electrode with a gap interposed therebetween and has a detection voltage applied thereto. The main electrode and the parallel electrode each have a base material, a first electrode member disposed on the base material, and a second electrode member disposed on the base material to cover the first electrode member, where the second electrode member has an electric conductivity that is lower than the first electrode member. The first electrode member is disposed on a lateral perimeter of the second electrode member to surround a center of the second electrode member.

摘要： A capacitance type sensor includes a sensor body part having a first detection electrode and a second detection electrode, which are arranged to face a detection object. The first detection electrode and the second detection electrode are arranged in a partially overlapping manner to form an overlap section. An area size of the overlap section between the first detection electrode and the second detection electrode decreases when the sensor body part deforms from a pressure exerted onto the sensor body part, in comparison to the area size of the overlap section when the sensor body part is in a normal state without deformation.
