Abstract: A selector switch in which an input obtained from a range of continuous analog signals is used to select from one of a set of discrete selections. Each selection is assigned a specified range of analog signals. Each range is separated from an adjoining range by a guard band of signals. A determination is made as to whether the input analog signal is within one of the specified ranges of analog signals. If so, a sector indicator is set to correspond to the specified range. Otherwise, the sector indicator is not changed.

Abstract: This invention is directed to a position detection system for a rotary motor element where color is used to determine the position of the rotary motor element. Different color light pulses are emitted in the direction of a color-coded disk which rotates in accordance with the rotary motor element. The light pulses are reflected back from the disk in distinct combinations which define the position of the rotary motor element. By determining which colors of light are reflected back, the position of the motor element may be determined. The apparatus may be located remote from the position detector to extend the life and the reliability of its electronic components. The angular resolution of a range of rotary positions is dependent upon the number of color regions on the color-coded disk and the number of different colors of light pulses that are emitted.

Abstract: A rotational position indicator useful for example for indicating wind direction is provided by a stator having nine position sensors substantially equally spaced around the circumference of a circle and an armature mounted for rotation on an axis located at the center of the circle. The armature is formed with two position sensor actuators mounted at approximately 140.degree. relative to each other. Each position sensor actuator is mounted at a radial position for selectively actuating the position sensors upon rotation of the armature. An electric circuit is coupled to each position sensor for indicating actuation or not of the respective position sensor. The output provides a unique position code for successive intervals of angular positioning of the armature relative to the stator. The actuators have an actuating effect over a selected angular interval sufficient to produce 36 unique position codes for indentifying successive 10.degree. intervals of angular positioning of the armature relative to the stator.
