ACTUATOR CONTROL CIRCUIT
First Claim
Patent Images
1. An actuator comprising:
- a single actuator housing containing within it a motor, a controller, a memory, and a position sensor having an output;
a user interface for causing a first threshold value to be stored in said memory; and
said controller configured and arranged to stop said motor as a function of said position sensor output and said first threshold value.

20. The method of controlling an actuator comprising the steps of:
-
providing an actuator having a single actuator housing containing within it a motor, a controller, a memory, a position sensor having an output, and a user interface for causing a first threshold value to be stored in said memory; receiving a signal over said user interface; storing a threshold value in said memory; reading a position sensor output; calculating a current position value, said position value being a function of said position sensor output; and preventing said motor from moving as a function of said current position value and said threshold value stored in said memory. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
