Abstract: A self-calibrating linear actuator is configured to control a spring return valve with variable stroke. The actuator includes a motor, a spindle coupled to an output of the motor, a motor controller coupled to the motor, a microcontroller coupled to the motor controller, and a back electromotive force (BEMF) circuit, coupled to the motor, configured to provide to the microcontroller a BEMF value for each motor step. The microcontroller is configured to determine a difference of a number of motor steps during operation of the actuator and to store the difference as a calibrated touch point for the actuator.

Abstract: An assembly includes a thermoelectric tripping device, a flange, and a gland. The thermoelectric tripping device is configured to be detachably coupled with a damper. The thermoelectric tripping device includes an extending arm including a fuse configured to trip at a pre-defined temperature. The flange is configured to be coupled to a surface of the damper. The gland is defined by a pair of fixtures positioned in-line with each other and having a passage configured therewithin to facilitate passage of the extending arm therethrough. A first fixture of the pair of fixtures is configured to be coupled with the flange, and a second fixture of the pair of fixtures is configured to be detachably coupled with the extending arm.
