TL;DR: In this article, a back-pounding and fan-switching robot with a base and a storage battery is shown to have the advantages of convenient operation, low manufacturing cost and automatic regulation and control.
Abstract: The utility model relates to a back-pounding and fan-swing robot, which comprises a back-pounding device, a base, a first infrared human body inductive sensor, a first timing switch, a storage battery, a second timing switch, a second infrared human body inductive sensor and a fan-swing device. The storage battery is arranged at the center of the base. The back-pounding device, the first infrared human body inductive sensor and the first timing switch are arranged on one side of the storage battery and the fan-swing device, the second infrared human body inductive sensor and the second timing switch are arranged on the other side of the storage battery. The arrangement of the back-pounding device, the first infrared human body inductive sensor and the first timing switch is symmetrical to the arrangement of the fan-swing device, the second infrared human body inductive sensor and the second timing switch. The fan-swing device, the second infrared human body inductive sensor, the second timing switch, the storage battery, the second timing switch, the second infrared human body inductive sensor and the fan-swing device are successively connected with each other into a pathway. The back-pounding and fan-swing robot has the advantages of simple structure, convenient operation, low manufacturing cost and automatic regulation and control and integrates the functions of back-pounding and fan-swing in one piece.

TL;DR: In this paper, a system for a machine with a plurality of proximity sensors, especially an automated production machine, is described, where each proximity sensor (3.1 to 3.s) comprises at least one secondary winding (2.1, 1.p) that is suitable for receiving energy from a medium frequency magnetic field.
Abstract: The invention relates to a system for a machine with a plurality of proximity sensors, especially an automated production machine. Each proximity sensor (3.1 to 3.s) comprises at least one secondary winding (2.1 to 2.s) that is suitable for receiving energy from a medium frequency magnetic field. At least one primary winding (1, 1.1 to 1.p) that is supplied by a medium frequency oscillator (4) is designed for the wireless supply of the proximity sensors (3.1 to 3.s) with electric energy. Every proximity sensor (3.1 to 3.s) is provided with a transmitter device which transmits radio signals that contain relevant sensor information to a central receiver device (9) that is linked with a process computer (10) of the machine. The invention also relates to a proximity sensor and to a corresponding primary winding.

TL;DR: In this article, the authors describe a monitoring circuit for an aircraft which consists of a multitude of air core inductors and capacitors, depending on the distance between the target and the inductive system, the frequency response of the system is changed.
Abstract: The present application describes a monitoring circuit for an aircraft. The monitoring circuit comprises an inductive system, wherein the inductive system comprises a multitude of air core inductors and capacitors. Depending on the distance between a target and the inductive system the frequency response of the inductive system is changed. The change in the frequency response is detected and displayed in a display unit. The monitoring circuit can be used to improve door monitoring in an aircraft.

TL;DR: In this paper, the authors describe a bar code reader with a head that contains an array of inductive sensors that are spaced relative to each other such that magnetic interference is limited, and the sensors sit above the bar code and are stationary.
Abstract: The bar code reader has a head that contains an array of inductive sensors that are spaced relative to each other such that magnetic interference is limited. The sensors sit above the bar code and are stationary. The length of the array exceeds that of the bar code. The sensor outputs are transmitted in sequence using a multiplexer. Two such arrays may be located in parallel. A computer receives the signals which undergo phase changes linked to the bar code pattern. The signals are demodulated for input to the computer. USE/ADVANTAGE - Allows reading without relative motion between head and code.
