The power system may include a main circuit arrangement having a power source, a load and a circuit breaker. The power system may additionally include an energy harvesting circuit arrangement connected to the main circuit arrangement. The energy harvesting circuit arrangement may include an operating switch and an energy harvester. The power system may also further include a trigger mechanism, which may be configured to, when detecting a current above a predetermined value in the main circuit arrangement, trigger the circuit breaker to switch from a closed mode to an open mode. The trigger mechanism may also be configured to trigger the operating switch to switch from an open mode to a closed mode for a predetermined duration, and back to the open mode after the predetermined duration, thereby storing electrical energy in the energy harvester.

This disclosure relates to various embodiments of rotary actuation devices that may be utilized in a variety of applications. In one embodiment, a rotary actuation device is configured to transition between a first position and a second position in response to each of a manual adjustment, an activation of an electrical actuator, and a force generated by a deck device. The rotary actuation device may be at least one deck device configured to exert a force in response to a condition. The force may cause the rotary actuation device to transition between the first position and the second position. The rotary actuation device may further include an electrical actuator configured to generate a motion upon activation. A rotary latch mechanism coupled to the electrical actuator and may cause the rotary actuation device to transition from the first position to the second position.
