TL;DR: In this paper, the authors described a miniature transformer with an inductive sensor (2) which is sensitive to the magnetic field produced by a leakage current from an earth conductor (12), called the primary.
Abstract: Device operates as a miniature transformer and comprises an inductive sensor (2) which is sensitive to the magnetic field produced by a leakage current from an earth conductor (12), called the primary. The sensor (2) produces an electric current, under the influence of the magnetic field, within the generator (24), which is called the secondary. An indicator (4) has a mobile shutter (14), which moves between two positions, conspicuous and neutral positions. The secondary current serves to move the shutter between neutral and conspicuous positions when there is a leakage current. The switch can only be reset manually by an operator.

TL;DR: An automatic vehicle tracking system based on inductance sensor that can implement the function of real-time display of time and distances, and has high precision and low power consumption was designed.
Abstract: Automatic vehicle tracking system based on inductance sensor was designed. This system uses inductive sensor for data acquisition controlled by STM32 microcontroller. The vehicle is made up of L298N motor drive module, geared motor module, buzzer sound module, LCD module, encoder module, bluetooth module, and battery module, and in order to change direction and speed by DC motor, its four-wheel drive vehicle can output variable pulse signals. Microcontroller continually scans four-channel data of LDC1614 and controls vehicle to complete tracing action. If an obstacle is detected by it, the buzzer module will make a sound prompts. The precise timing can be obtained by the timer module, and the encoder module is designed to measure the speed of the vehicle. The designed system can implement the function of real-time display of time and distances, and has high precision and low power consumption.

TL;DR: In this article, the authors describe a proximity sensor used by an operation robot that may measure a proximity distance to an object using an ultrasonic wave in a device such as an operating robot, an endoscope, and the like.
Abstract: Described is a proximity sensor used by an operation robot that may measure a proximity distance to an object using an ultrasonic wave in a device such as an operation robot, an endoscope, and the like, and a method of operating the proximity sensor which may be used by an operation robot. The proximity sensor used by the operation robot may include an inner wall provided in a circular structure to secure a cavity within the circular structure, a piezoelectric polymer film disposed outside the inner wall to generate an ultrasonic signal, and to sense the ultrasonic signal, and an outer wall disposed outside the piezoelectric polymer film to propagate the ultrasonic signal via an open window, thereby preventing a collision between devices or an unnecessary contact, and providing a more stable operation environment.

TL;DR: In this paper, a tunable proximity sensor 210 and a method of manufacturing the same are disclosed, which includes a cap 230 with different sections having different dielectric constants, shapes, and/or thicknesses.
Abstract: A tunable proximity sensor 210 and a method of manufacturing the same are disclosed. The proximity sensor includes a cap 230 with different sections having different dielectric constants, shapes, and/or thicknesses. As the cap 230 is rotated with respect the sensing element, these non-uniform sections induce a different loading on the sensor element from the electromagnetic field, allowing the proximity sensor 210 to be tuned.

TL;DR: In this paper, a method for determining the angular position of a rotating machine by way of an inductive sensor was proposed, based on the excitation signal for the primary winding and voltages induced in the two secondary windings of the sensor.
Abstract: The invention relates to an assembly and to a method for determining the angular position of a rotating machine by way of an inductive sensor (1). From the excitation signal (17) for the primary winding (2) of the sensor and the voltages induced in the two secondary windings (3, 4) of the sensor, three more signals are derived using phase shifters (9, 10, 11) and polarity sign determination units (12, 13). The six signals in total are sampled using a sample and hold sampling unit (14) and provided to a processor (15) for evaluation, which then calculates the current angular position of the rotating machine at the sampling time.
