Abstract: In various embodiments, the energy efficient power supply utilizes switching control energy from an onboard energy storage device, or from an external utilization device power, to power the switching function of the power supply to switch between a zero energy use state, and an energized state, providing standby, low-draw, measured-demand, and full-output energy; variable, as the utilization device, or devices, require. Energized switching control is achieved by completing, or providing, the control circuit when the power supply is connected to a utilization device, or devices, or when the power supply is connected to a utilization device, or devices, and a utilization device signals, or when utilization devices signal, that power is needed from the power supply. De-energized switching control is achieved by disconnecting the power supply from a utilization device, or devices, or when a utilization device signals, or when utilization devices signal, that power is no longer needed from the power supply.

Abstract: In various embodiments, the present invention includes a rupture control system comprising an inner hose, an outer hose, and a valve that is actuated by fluid leaking from the inner hose. The inner hose and the outer hose define a containment passageway therebetween, and the valve includes an inlet, an outlet, a passageway extending between the inlet and the outlet, a valve member readily movable between a first position and a second position, and a valve control chamber. In these embodiments, a rupture in the inner hose places the inner hose in fluid communication with the containment passageway and the valve control chamber, and fluid flowing into the valve control chamber moves the valve member from its first position into its second position, the valve member at least partially blocking the valve passageway in the second position.
