Auto-adjusting electric rear-view mirror for car, has servo circuit comparing feed back signal with signal from entry port of circuit to transmit control signal towards corresponding driving mechanisms, and keys with master control circuit

摘要

The mirror has a sensor unit detecting position variation of a mirror unit to transmit a feedback signal towards a servo circuit which compares the signal with a signal from entry port of the circuit to transmit a control signal towards corresponding driving mechanisms. A master control circuit is coupled to the servo circuit and an outer control device for the servo circuit to directly control the corresponding mechanism based on a control signal transmitted by the device. Keys are coupled to the control circuit for entering a control signal in the control circuit.
