Claim:
1. A movable barrier system comprising: a movable barrier pivotally connected to a movable barrier pivot connection; a linear actuator with a first end pivotally connected to the movable barrier and a second end pivotally connected to a linear actuator pivot connection; a processor configured to variably control an operation speed of the linear actuator during operation thereof between a first position of the movable barrier and a second position of the movable barrier based on a position of the movable barrier pivot connection relative to a position of the linear actuator pivot connection; an input device operatively coupled to the processor to input information regarding the position of the movable barrier pivot connection relative to the position of the linear actuator pivot connection; wherein the processor is configured to variably control the operation speed of the linear actuator in response to a ratio of a distance from the linear actuator pivot connection to a fixed point and a distance from the movable barrier pivot connection to the fixed point as determined from the information received from the input device.
