摘要： Tap or current collector for rotary or linear potentiometers, displacement pick-ups, variable resistances, brushes/collector junctions of electric motors, etc., wherein the tapping part on which the slider elements as such are mounted and which performs a relative movement with respect to the tapped path or collector carries the slider elements having individual resilient and freely movable slider fingers, at least in the contact area proper, and which are mounted on a mounting block in such a manner, relative to the sense of displacement, that irrespective of the sense in which the tap moves at any time, one of the slider elements is always pushed, and the other one is always pulled so that even the influences on the tapped or transmitted electric signal of dynamical effects developed by high accelerations are compensated. Further, the individual slider elements are pre-bent along their longitudinal extension so that they follow a pre-determined curve in the inoperative condition and assume a substantially straight shape when applied under resilient pressure to the path to be scanned, whereby the distance between the tap and the path can be minimized.

摘要： A potentiometer circuit by which a continuous, sawtooth 360 degree ramp output voltage is obtained from a single turn continuous rotation potentiometer having an annularly disposed resistance element and two angularly displaced rotatable wipers providing displaced voltages from the resistance element. The circuit includes comparator means responsive to one of the wiper voltages providing a comparator output signal and switch means responsive to the comparator output signal for switching between the wiper voltage outputs to provide a continuous, sawtooth 360 degree ramp analog output voltage. An analog-digital converter may be connected to it to provide a digital output voltage.

摘要： An inductive displacement sensor having a displaceable or rotatable, magnetically permeable measuring head, at least one measuring loop whose geometric shape varies in response to the longitudinal/rotary displacement of the measuring head, and at least one excitation loop by which a magnetic flux can be generated in the measuring head. The flux penetrates the at least one measuring loop at any point of the longitudinal/rotary displacement, essentially in the region of the measuring head, and inducing an electric measuring signal (i2). A resonant circuit, which is electrically decoupled from the outside, is arranged on the measuring head and is excited in correct phase relation by a short voltage pulse after a number of, preferably, 10 to 20 free oscillations.
