Title: Converting position into electrical impulses - using inductive sensing of core position w.r.t. antiphase coils and phase differencing
Inventor: HOLZAPFEL JUERGEN
IPC: G01D5/22
Filed: 1978-12-18
Abstract: A circuit converting different positions into electrical impulse produces high resolution indication of a shaft rotary position. A sensed force is converted into a displacement. It is applicable to weighing and length measurement and involves low manufacturing costs. For weight measurement the balance mechanism itself is the force sensor and the circuit measures the position of an attached core. Otherwise the core is part of a force sensor. Coils are driven with rectangular pulses. The voltage rises in their series resistors are indicative of the coil inductances. The position of the core, which protrudes into the coils in antiphase, is a measure of the displacement and determines the coil inductances. The resistor voltages are amplified and their phase difference during the rise period used to generate counter pulses.

Patent DE-2926561-A1 (DE)
Inventor: ALTMANN GEB HARMS JUERGEN
IPC: G11C27/02
Filed: 1979-06-30
Abstract: The precise analysis of transient measurement values arriving simultaneously available directly or as electrical signals, required heretofore a very large range of means. In order to reduce the importance of such required means, the signals arriving simultaneously are stored in a memory in an analog form while preserving their time and amplitude information, are delayed by a given time interval different for each signal and are then transmitted on a same output line. Hence, at the input of the signal processing system which comes next, the initially simultaneous signals are provided successively, but are kept and changed and may be processed successively.
