Abstract
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 the memory, and the controller configured and arranged to stop the motor as a function of the position sensor output and the first threshold value.
Claims28
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.

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.
