Abstract: A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.

Abstract: A thermodynamic apparatus that includes a displacer within a cylinder is disclosed. The displacer reciprocates within the cylinder by a linear actuator that includes electrical coils, an armature, and a coil spring system. The spring system includes collinear first and second coil springs of opposite sense. First ends of the springs are captured in a first plate; second ends of the springs are captured in a second plate. Without constraint, the springs can compensate to forces by bending, rotating, increasing in diameter, and combinations thereof. In certain applications, such as the heat pump, bending should be minimized. By selecting the points of capture of the hooks at the ends of the springs in the plates, bending force of the first spring counteracts the bending force of the second spring.
