Abstract: A system has a power source connected to power access points and at least one environmental control system. A threshold compare device is effective to compare the proportional load on the environmental control systems to a preset threshold. If the threshold is exceeded, unused power access points are disabled. This prevents such access points from placing additional loads on the environmental control systems. Conversely, when the proportional load on the environmental control systems drops below a preset threshold, power can be restored to the disabled power access points. A master control unit can monitor the load on the environmental control systems and either or both the environmental conditions in environment zones or the power loading of the power access points and determine whether to disable unused power outlets.

Abstract: An outlet provides both AC and DC power to at least one device. The outlet includes an input portion adapted to receive a first voltage input and a second voltage input wherein the first voltage input is a variable DC voltage and the second input is AC of a desired voltage and frequency. A converter reduces the first input voltage to a constant DC voltage output effective to power a PED. The outlet has a first receptacle in the form of a USB port to deliver the DC power to the device and a second receptacle to deliver the AC power to the device. A sensing circuit is coupled to the outlet and determines if a source of the second voltage may safely provide the AC power.

Abstract: In a method of thermal management, a temperature is sensed and compared with a first preset temperature. The lowest priority load is disabled in response to the temperature being equal to the first preset temperature.

Abstract: An embodiment of the present invention comprises apparatus for and method of managing and distributing power from a supply of limited power. A plurality of outlets is connected to a plurality of power units. In accordance with the present invention, an amount of power drawn by the outlets is measured and compared to a first predetermined electrical power level and a second predetermined electrical power level. When the amount of measured power being drawn exceeds the second predetermined maximum electrical power level, all outlets are disabled. When the amount of measured power being drawn is less than both the first predetermined electrical power level and the second predetermined electrical power level, all outlets are enabled. When the amount of measured power being drawn exceeds the first predetermined electrical power level, outlets currently in use by a power utilizing device are enabled while outlets not currently in use by a power utilizing device are disabled.

Abstract: An apparatus for and method of managing and distributing power from a supply of limited power is described. A plurality of outlets are connect to a plurality of power units. As additional outlets are used, the invention measures the amount of power drawn by the outlets. Outlets are enabled if the amount of measured power is less than a maximum amount of power available. Additional outlets not currently in use are disabled if the amount of measured power is greater than the maximum amount of power available.
