TL;DR: In this paper, an inductive proximity sensor is created by means of which distances travelled can be continuously detected, provided that the oscillator magnetic core (7) is premagnetised to the or up to closely before the transition region from linear magnetisation characteristic to flattened saturation line, and that the magnetic core is located, at least with its saturation-sensitive area, between two magnetic flux conducting pieces for the additional magnetic field (N-S), which extend over the approach path to be detected, and a magnetic flux bridge (11), which can be moved along the conducting pieces,
Abstract: An inductive proximity sensor has an RF oscillator (6) with saturation-sensitive oscillator magnetic core (7), the state of saturation of which, and thus the state of oscillation of the oscillator (6), can be varied by the approach or removal of an additional magnetic field (N-S), there also being provided an evaluating circuit (18) for the state of oscillation. An inductive proximity sensor is to be created by means of which distances travelled can be continuously detected. For this purpose, it is provided that the oscillator magnetic core (7) is premagnetised to the or up to closely before the transition region from linear magnetisation characteristic to flattened saturation line, that the oscillator magnetic core (7) is located, at least with its saturation-sensitive area, between two magnetic flux conducting pieces (10) for the additional magnetic field (N-S), which extend over the approach path to be detected, and that a magnetic flux bridge (11), which can be moved along the conducting pieces, is provided between the two conducting pieces (10).

TL;DR: In this paper, a gesture-controlled automatic sensor faucet based on gesture control application is presented, in which a light inductive sensor is arranged at the upper end of the housing and is connected with a sensing control circuit, and the sensing controller circuit connects with the cold and hot water dual-switch valve by arranging a valve driving circuit.
Abstract: The invention relates to the field of faucets, in particular to an automatic sensor faucet based on a gesture control application. The faucet comprises a housing, a cold water inlet pipe, a hot water inlet pipe and a mixed water outlet pipe, wherein the cold water inlet pipe, the hot water inlet pipe and the mixed water outlet pipe are communicated with a cold and hot water dual-switch valve respectively, a light inductive sensor is arranged at the upper end of the housing and is connected with a sensing control circuit, and the sensing control circuit is connected with the cold and hot water dual-switch valve by arranging a valve driving circuit. The cold and hot water dual-switch valve is controlled through swing of the hand on the light inductive sensor, and the water volume well-adjusted in water temperature is supplied in a constant proportional increase and decrease mode, so that the automatic sensor faucet supplies an appropriate amount of water with appropriate temperature according to the demand of a user.

TL;DR: In this article, an induction safety valve with a magnetic exchange valve and a magnetic-exchange valve is presented. But the model is restricted to the utility model, and the inductive sensor is fixedly installed on the surface of the other side of the left side cover of the sliding column.
Abstract: The utility model discloses an induction safety valve with a magnetic exchange valve. The induction safety valve with the magnetic exchange valve comprises a hollow valve body and the magnetic exchange valve, wherein a first oil inlet channel and a second oil inlet channel are formed in the two ends of the valve body respectively, a sliding column is arranged in the valve body in a sliding mode, a left side cover and a right side cover are arranged at the left end and the right end of the valve body respectively, a first spring is arranged between the left side cover and the sliding column, a second spring is arranged between the right side cover and the sliding column, an inductive sensor is fixedly installed on the surface of the other side of the left side cover, an induction iron core is arranged at the end, close to the inductive sensor, of the sliding column, the induction iron core penetrates through the left side cover, and then extends into the inductive sensor, the induction iron core is sleeved with the first spring in a connection mode, and a control oil port which is used for controlling a main oil circuit of the induction safety valve to be connected or disconnected is further formed in one side face of the valve body. Due to the fact that the inductive sensor is used as a monitoring sensor, when the induction iron core moves in a coil L of the inductive sensor, changes of the coil L are obvious, and sensitivity of the monitoring sensor is improved.

TL;DR: In this article, the coupling of a sensor element to a transponder, the connection of said sensors element to the transponders being achieved by capacitive or inductive coupling, is described.
Abstract: The invention relates to the coupling of a sensor element to a transponder, the connection of said sensor element to the transponder being achieved by capacitive or inductive coupling. This enables any separation layer that may lie between the sensor element and the transponder to be retained, allowing the invention to be advantageously used in gas and liquid-tight containers, such as tires. In addition, electrically non-conductive materials of the object to be measured can be used as a dielectric for the capacitive coupling and electrically conductive parts can form part of a conductor loop for the inductive coupling.
