Proximity sensing structure and electronic device having proximity sensing capability

Abstract: The present invention relates to a proximity sensing structure, which is disposed in an article for detecting whether an object approaches the article. The article can be an electronic device. The proximity sensing structure comprises a first sensing electrode, a wire, a second sensing electrode, and a proximity sensor. Both ends of the wire are coupled electrically to the first and second sensing electrodes, respectively. The proximity sensor is coupled electrically to the wire, the first sensing electrode, and the second sensing electrode, and detects whether the object approaches the article according to an electrical status of the wire, the first sensing electrode, and the second sensing electrode. Thereby, the proximity sensing structure according to the present invention uses the wire to increase the sensing area. In addition, the wire design makes the disposal of the proximity sensing structure more flexible.

Inductive edge detector for paper machinery

Abstract: The invention is directed to a continuous belt edge detector system for use in a paper making machine having a continuous belt guide device. The edge detector system comprises a continuous belt having an edge dope with metallic particles therein and an inductive sensor connected to the guide device and adjacent the edge dope. The inductive sensor sends a signal to the guide device indicative of a location of the continuous belt. The guide device moves the continuous belt, e.g., transversely relative to the running direction of the belt within the machine, dependent on the inductive sensor signal.

Inductive proximity sensor - has oscillator in bridge circuit in branch of current source and continuously restores bridge balance

Abstract: The inductive proximity sensor has an oscillator module (Z3) containing a coil (L1) which is damped by the presence of an object (6). The module forms a branch (3) of the DC supplied (UB) bridge circuit (1 to 4) such that a resultant voltage change (RV) is evaluated (S) for analogue digital load control via the voltage (VA). A branch (1) of the bridge (1 to 4) contains an impedance (Z1) exactly matched to the oscillator's static impedance (Z3) and of identical thermal construction. An AC source (8) controlled by the evaluation unit(s) continuously restores the bridge (1 to 4) balance with the resultant minimisation of source voltage and thermal errors. USE/ADVANTAGE - Also for analogue path measurement. Has improved accuracy and long-term stability as consequence of thermal compensation and insensitivity to spurious oscillatory influences. Is universally applicable to both analogue and digital systems.
