Abstract: A coordinated multiple power management system provides an efficient and unique means of controlling the power usage of devices attached to a personal energy platform. Power control in an abundant power situation (i.e. commercial power is available) saves money. Power control in a constrained power situation (i.e. commercial power is unavailable e.g. “power failure”) provides more availability of needed computing services (for example, emergency activities, enable longer communication periods, longer video streaming, security monitoring, internet access and communications, or critical healthcare device usage etc.). The power supplied to the devices can be determined automatically and is under program control, which allows the complete management and distribution of power to any, and all, devices attached to the personal energy platform.

Abstract: A time-admittance fault detection and isolation system includes a series of time-admittance switches spaced apart along the power line, each including a respective time-admittance function. Together, the time-admittance functions define a cascade trip sequence in a downstream-to-upstream direction, which autonomously causes a closest upstream time-admittance switch to a fault to trip to isolate the fault on an upstream side of the fault without communication with the time-admittance switches. The fault detection and isolation system may also include a radio communicating a trip signal from the closest upstream time-admittance switch to the fault to a closest downstream time-admittance switch to the fault. The trip signal causes the closest downstream time-admittance switch to the fault to trip to isolate the fault on a downstream side of the fault. A tie switch closes to back-feed a portion of the electric power line downstream from the closest downstream time-admittance switch to the fault.
