TL;DR: In this paper, a micro-machined inductive sensor emits an alternating magnetic field in order to detect position and or movement of an object (O), which is capable of modifying the magnetic field, by means of a discontinuity (D,C).
Abstract: Micro-machined inductive sensor emits an alternating magnetic field in order to detect position and or movement of an object (O), which is capable of modifying the magnetic field, by means of a discontinuity (D,C). The sensor comprises a planar emitting coil (10), which radiates the alternating magnetic field and one or more planar receiving magnetic coils (11-14), arranged in such a manner as to capture a certain part of the radiating field and variations in the field caused by discontinuities in the object (O). The coils are machined on the common substrate by a selective photolithography process. In the areas where the emitter coil (10) is contiguous with the receiver coils (11-14) a shielding strip galvanically independent of the coils (10-14) is connected to a reference potential. The shielding strip is formed by deposition of a metal skin on the substrate.

TL;DR: In this article, the authors propose a method for operating a sensor system, having at least one capacitive sensor element, which is attachable to the surface of machines or machine parts, electrical field lines on the sensor element changing in the event of an approach and/or a contact of a body or object, which, based on the detected change of the field lines, triggers a safety function on the machine or the machine part.
Abstract: A method for operating a sensor system, having at least one capacitive sensor element, which is attachable to the surface of machines or machine parts, electrical field lines on the sensor element changing in the event of an approach and/or a contact of a body or object, and the at least one sensor element being connected to a control unit, which, based on the detected change of the field lines of the at least one sensor element, triggers a safety function on the machine or the machine part. The at least one sensor element has, in addition to fulfilling the safety function, an operating function, which is concluded from the location of the at least one sensor element and the time curve of the change of the field lines, and the safety function has priority over the operating function in a base state of the sensor system.

TL;DR: In this article, the authors proposed a short-circuit direction indicator for high-voltage lines fed from two ends in three-phase systems using Zener diodes in trapezoidal form.
Abstract: The invention relates to short-circuit direction indicators for high-voltage lines fed from two ends in three-phase systems. In such devices, it is usual to use a capacitive sensor for the voltage and an inductive sensor for the current and to transfer the sinusoidal quantities via Zener diodes in trapezoidal form. It is the object of the invention to improve known devices by simple means in such a manner that they still reliably indicate even with a collapse of the voltage in the short-circuit case. This is achieved by the fact that the star or delta voltage triggers a synchronous oscillator (2) which continues to run with the correct phase in the short-circuit case and is used as phase frequency, that the signals (U20, U21) of the sensors (1, 3) are supplied to a drive logic (4) and that the drive logic (4) output is connected to a phase measuring unit (6) consisting of logic gates, the output of which feeds direction indicating elements (LED1, LED2).

TL;DR: In this paper, an inductive sensor is connected with the controller so that the sensor provides measurement information for the controller, where the information is correlated with instantaneous conductibility of the liquid in the bowl.
Abstract: The device (100) has a bowl (101) for accommodating liquid e.g. water and oil, and food, and a heating device for heating the liquid. A controller (110) controls heating of the liquid, and an inductive sensor (120) comprises an active zone with annular shape for surrounding an opening (121). The active zone is arranged in the bowl so that the liquid flows through the opening. The sensor is connected with the controller so that the sensor provides measurement information for the controller, where the information is correlated with instantaneous conductibility of the liquid in the bowl. An independent claim is also included for a method for preparing food.
