Abstract: A system and method for remote health monitoring is described. One embodiment includes a portable health monitoring device comprising a data transfer interface configured to receive a protocol, wherein the protocol comprises branching logic, a display configured to present a user with at least one question from the branching logic, a user interface configured to receive information from the user, a diagnostic device interface configured to communicate with a diagnostic device, a memory configured to store data related to the user, and a processor configured to analyze at least a portion of the data related to the user, wherein the processor is further configured to transmit at least a portion of the data related to the user to a monitoring location via the data transfer interface.

Abstract: A ground fault interrupter, operable in a measurement state, is employed with a DC circuit having a DC power source and a load. The DC source supplies DC current to the load along a supply current path and receives DC current from the load along a return current path. The ground fault interrupter comprises a first resistance in series with the supply current path, a second resistance in series with the return current path, and a current interrupter disposed in series with one of the current paths. The current interruptor interrupts the one of the current paths in response to actuation of the current interrupter. The ground fault interrupter further includes a measurement unit for measuring voltage drops across the respective first and second resistances during the measurement state, obtaining a measurement value using a difference between the voltage drops, and comparing the measurement value to a predetermined threshold.
