A shape encoder then encodes the segmentation masks, a position encoder encodes a position of each pixel, and a color encoder encodes a color of each pixel.

The magnetic angle sensor may also function as an incremental position encoder.

The position encoder provides encoder signals which are used as a clock signal for a pattern memory (136).

The trigger initiates acquiring a position signal (315) from the absolute rotary position encoder (310).

The position encoder provides an electrical output indicative of the position of the slider on the supporting plate.

The pan mechanism includes a pan motor and a pan position encoder.

A position encoder coupled to the active portion provides position data indicative of a position of the active portion.

A rotor position encoder (14) determines the angular positions of the rotor.

The tilt mechanism includes a tilt motor and a tilt position encoder.

A position encoder is provided for indicating the relative position between first and second relatively movable members.

A position encoder is provided for indicating the relative position between first and second relatively move members.

A position encoder (118) is associated with each servo motor (116) and outputs position information to a controller (120).

The lower end of the sleeve (8) is connected with a first shaft encoder (9).

The output of the first shaft encoder (9) is connected with the control module (4).

The output of the second shaft encoder (11) is connected with the control module (4).
