Abstract: Existing AC power distribution infrastructure in a building is leveraged for the DC power distribution, where one or more DC powers are delivered over an existing power distribution circuit and existing AC power sockets. A DC power attachment is coupled to an existing AC power socket to provide various DC voltages, including a high DC voltage for high power DC devices and a low DC voltage for low power DC devices. Transition from the AC centric environment to a DC environment is thus simplified thereby improving energy usage efficiency and making DC power readily available.

Abstract: An exercise device including a base plate having a generally circular wall extending upwardly therefrom to define a base body having an interior cavity. Spaced apart roller assemblies are disposed within an interior of the base body. A generally convex dome of a motion platform assembly is at least partially disposable within the base body so as to contact the roller assemblies. The motion platform assembly slides, tilts or rotates as force is applied to an upper support platform. A lip of the motion platform assembly may contact a rim of the wall to limit a range of motion of the motion platform assembly. One or more elastic cords extending between the base body and the motion platform assembly provide resistance to motion of the platform assembly.

Abstract: A method selects between AC and DC power inputs for delivery to power distribution circuits in a building. Power distribution circuits includes power distribution wiring and a socket. Power distribution wiring connects between the socket and a circuit breaker and is selectively coupled through the circuit breaker to either the AC or DC power input. DC and AC power inputs, and the circuit breaker are dispositioned at a building service panel. The method includes monitoring a voltage level of the DC power input using a detection circuit in the circuit breaker, using a switch circuit in the circuit breaker to couple the power connection wiring to the AC power input when the detection circuit detects the voltage level is below a threshold level, and coupling the power connection wiring to the DC power input when the detection circuit detects the voltage level is equal to or above the threshold level.
