摘要： The application provides a method for measuring a shortest distance between capacitances and a method for evaluating a capacitance manufacture procedure. The method for measuring the shortest distance between the capacitances includes: obtaining a distance between tangent lines of adjacent surfaces of two adjacent capacitances, and taking the distance between the tangent lines of the adjacent surfaces of the two adjacent capacitances as the shortest distance between two capacitances. The tangent lines of the adjacent surfaces of the two adjacent capacitances have a same direction, and the direction of the tangent lines is perpendicular to a preset arrangement direction of the capacitances.

摘要： A sensing system determines movement and position of passengers and objects within a vehicle. The sensing system comprises a group a group of transmitting antennas operably connected to a car seat, each transmitting antenna adapted to transmit a signal that is orthogonal to each other signal transmitted during an integration period; a plurality of receiving antennas, each one of the plurality of receiving antennas adapted to receive transmitted signals; and a processor adapted to determine a measurement of the transmitted signals received and create a heatmap, wherein a heatmap summation is taken during no-touch events, compared to a baseline heatmap, and a new baseline heatmap recalibrated if a threshold is exceeded.

摘要： An inductive sensor (10) has a substrate (20), on which multiple transmitter/receiver coils (31, 32, 33) are arranged side by side. It can be operated in such a way that the transmitter/receiver coils (31, 32, 33) are each stimulated independently of one another at a frequency of more than 100 MHz.

摘要： Systems and methods for measuring air gaps between opposing surfaces of two structural components. In one application, such measurements are used to fabricate a shim that fills the air gap between two structural members, such as parts of an aircraft. The resonant inductive coupling-based sensing system has the capability to remotely measure an air gap using an on-board transmit system. Furthermore, the system has the capability to switch between multiple inductor-capacitor sets such as to simultaneously measure air gaps across an area so that a better profile of the air gap can be determined. The resonant inductive coupling-based gap sensor is configured as signal generating and signal sensing electronics printed or mounted on respective flexible substrates to provide a flexible and portable measurement solution.

摘要： Described is a security sensor comprising two or more sub-sensors for use in a variety of installations where different magnetic fields may be experienced by the security sensor as a result of the variety of installations. One of the sub-sensors may have a low magnetic sensitivity while the other sub-sensor may have a much higher sensitivity to magnetic fields. In operation, one or both sub-sensors are used to determine if a door or a window has been opened.
