    Abstract: An inductance coil sensor in which a rotating spoiler (46) alters the inductance of a stationary coil (1230/1432) having two parts (12a, 12b; 30a, 30b/14a, 14b; 32a, 32b) disposed on opposite sides of the spoiler. Changes in inductance of the stationary coil are sensed to develop an indication of the rotary movement of the spoiler which, in turn, represents changes in the parameter being monitored. By locating one part of the stationary coil above the spoiler and one part below the spoiler, compensation is provided for undesired movements of the spoiler along its rotation axis.

    Abstract: Non-contacting sensor apparatus having two tank circuits from which an indication of the position of the moving part of the sensor is developed by measuring the relative resonance frequencies of the two tank circuits. As the moving part of the sensor changes position, the relative resonance frequencies of the two tank circuits change. The outputs of the two tank circuits are multiplexed and drive a pulse generator which develops a first series of pulses having a repetition rate which corresponds to the resonance frequency of one of the tank circuits and a second series of pulses having a repetition rate which corresponds to the resonance frequency of the other tank circuit. The relative times required to count the same number of pulses of each series of pulses provides an indication of the position of the moving part of the sensor.

    Abstract: A musical keyboard having keys which carry metal spoilers that alter the resonance characteristics of tank circuits associated with the keys as the keys move toward and away from the inductance coils of the tank circuits. The tank circuits are connected sequentially to a frequency sensing circuit which develops indications of key positions by sensing the resonance frequency of each tank circuit.

    Abstract: The accurate detection of a change in a monitored parameter is accomplished by an inductance non-contacting coil sensor that has a stationary coil which is composed of two parts which are disposed on opposite sides of a spoiler. One part of the stationary coil includes planar metal coil parts (12a, 12b, 14a, 14b) which are located on an insulating board (10). The other part of the stationary coil includes metal coil parts which are located on another insulating board (28). Planar metal coil parts (12a, 12b) which are located on opposite sides of the insulating board (10) are connected via a through hole (16). Similarly, planar metal coil parts (14a, 14b), (30a, 30b), (32a, 32b) are located on opposite sides of their respective insulating boards (10, 28, 28) via respective through holes (18, 34, 36). A spoiler (46) on a shaft (48) is positioned between the two insulating boards. By disposing the spoiler between the two parts of the stationary coil compensation is provided for undesired movements of the spoiler along its rotation axis.
