Abstract
A method of controlling operation of a linear actuator, including maintaining the linear actuator in equilibrium when supporting a first load, determining application of a second load on the linear actuator, and selectively actuating the linear actuator in response to application of the second load on the linear actuator.
Claims17
A method of controlling operation of a linear actuator, said method comprising:
- maintaining the linear actuator in equilibrium when supporting a first load;
- determining application of a second load on the linear actuator;
- and
- selectively actuating the linear actuator in response to application of the second load on the linear actuator by:
- causing the linear actuator to extend when the second load applied to the linear actuator is a negative load;
- and
- causing the linear actuator to retract when the second load applied to the linear actuator is a positive load;
- and
- varying a rate of extension and retraction of the linear actuator proportionally as a function of the value of the second load.
A computer-readable storage media having computer-executable instructions embodied thereon for use in controlling operation of a linear actuator, wherein, when executed by at least one processor, the computer-executable instructions cause the processor to:
- maintain the linear actuator in equilibrium when supporting a first load;
- determine application of a second load on the linear actuator;
- and
- selectively actuate the linear actuator in response to application of the second load on the linear actuator by:
- causing the linear actuator to extend when the second load applied to the linear actuator is a negative load;
- and
- causing the linear actuator to retract when the second load applied to the linear actuator is a positive load;
- and
- vary a rate of extension and retraction of the linear actuator proportionally as a function of the value of the second load.
