1. A method for positioning a mirror comprising:
- (a) providing a mirror including a reflective surface;
(b) a carrier assembly attached to said mirror surface, said carrier assembly including a first motor for adjusting the angular orientation of the mirror by said motor;
(c) a signal pickup for electrically picking up a signal for each rotation of the motor shaft;
(d) measuring the rotation of the shaft between a first position and a second position for providing a position index for positioning said reflective surface at any predetermined point between said first and second position; and
(e) establishing a base point for positioning of said mirror surface by driving the motor to a stop at one of said first and second positions and thereafter actuating said motor to a predetermined position between said first and second positions.

14. A mirror for a vehicle comprising:
-
a mirror housing;
a multiplexing chip mounted in said housing;
a wiring harness connecting said multiplexing chip to a controller inside a vehicle; and
a thermistor connected to said multiplexor wherein said thermistor curve is linearized by said multiplexor and said multiplexor and the linearization is used to adjust for temperature induced fluctuations in the electronic control. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for positioning a mirror comprising:
-
(a) providing a mirror including a reflective surface;
(b) a carrier assembly attached to said mirror surface, said carrier assembly including a first motor for adjusting the angular orientation of the mirror by said motor;
(c) a signal pickup for electrically picking up a signal for each rotation of the motor shaft;
(d) measuring the rotation of the shaft between a first stop position and a second stop position along either a first or second axis and averaging the result to provide a zero position index for positioning said reflective surface at any predetermined point between said first and second position; and
(e) establishing a base point for positioning of said mirror surface by driving the motor to said zero position, and thereafter actuating said motor to a predetermined position between said first and second positions by advancing the motor from said zero position to said predetermined position. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A mirror having a plurality of controllable features selected from the group consisting of mirror adjustments, fold control, heating, lighting, memory, turn signals, temperature read-out, and intercom functions, said mirror comprising:
-
a mirror housing;
a multiplexing chip contained within said housing;
said multiplexor including a three wire serial connection to a control interface for controlling said controllable features;
at least one motor having a rotatable shaft for positioning of a mirror in a predetermined position within said housing along a first axis, the rotations of said shaft being counted and stored in said multiplexor memory from at least one zero position, said multiplexor storing a predetermined mirror position and indexing to said zero position prior to moving said mirror into said predetermined position along said first and second axis. - View Dependent Claims (31, 32)
