    Abstract: A monitoring system for determining whether an object is touched by a living body includes a receiver and a piezoelectric sensor attached to a substrate such that when the substrate is attached to the object. The piezoelectric sensor generates an output signal as a function of whether the living body is in contact with at least one of the substrate and the object. A processor processes the output signal to determine whether the living body is in contact with at least one of the substrate and the object and outputs a contact information signal containing information indicative of whether the living body is in contact with at least one of the substrate and object based on the determination. A transmitter transmits the contact information signal to the receiver.

    Abstract: A high-frequency module includes a mount board, a wave splitter chip mounted on one principal surface of the mount board and including a transmission filter and a reception filter, a first inductor chip mounted on one principal surface of the mount board and including an inductor, and a second inductor chip mounted on one principal surface of the mount board and including an inductor. The first and second inductor chips are disposed adjacent to each other and each has a polarity. The first and second inductor chips are disposed such that the polarities thereof are opposite to each other, as viewed from the reception filter.

    Abstract: A pressing sensor is provided that generates an output voltage of a first polarity by deforming with an operation plate when a part of a user's body touches the operation plate, and generates the output voltage of a second polarity by deforming with the operation plate when the part of the user's body is moved away from the operation plate. Moreover, a calculation unit calculates an electrical parameter integral value by time-integrating an electrical parameter that changes with the output voltage generated by the pressing sensor. The electrical parameter has a third polarity when the output voltage has the first polarity and has a fourth polarity when the output voltage has the second polarity. The calculation unit calculates a subtraction electrical parameter integral value obtained by subtracting a predetermined value having the third polarity per unit time from the electrical parameter integral value.

    Abstract: An electronic device that includes a housing and a piezoelectric sensor. The piezoelectric sensor is disposed in contact with an inner wall surface of the housing while in a bent state. The piezoelectric sensor includes a piezoelectric film, a coverlay, a first electrode, a second electrode, a third electrode, and a substrate having flexibility. The first electrode is disposed on a surface of the substrate. The first electrode includes a wide part and a narrow part. The coverlay covers a boundary between the wide part and the narrow part. The piezoelectric film covers a boundary between a part of the first electrode which is covered with the coverlay and a part of the first electrode which is not covered with the coverlay.

    Abstract: A pointer includes: a pointer tip having a tip configured to point a position; a transmitter configured to emit a signal from the pointer tip; and a main body connected to the pointer tip. The main body includes: an exterior housing forming an exterior; a detector configured to detect displacement of the exterior housing and output a detection signal; and a controller configured to change an operation state of the pointer in accordance with the detection signal. The detector includes: a detection device provided on an inner surface of the exterior housing and configured to detect the displacement; and a signal outputter configured to output the detection signal in the case where the detection device detects the displacement.
