    摘要: A method for determining position of a device includes generating at least two, time-varying, magnetic fields using inductive elements, wherein the fields have differing phases. The method further includes detecting a signal modulated on top of the fields, wherein the signal is generated from the device, and determining a position of the device based on a phase difference of the signal from the device and a reference signal.

    摘要: A system and method for managing electrically isolated fuel cell powered devices within an equipment rack is disclosed. The system discloses: an equipment rack; fuel cell devices; a fluid bus; a fluid manifold, coupling the fluid bus to each of the fuel cell devices; and an external fuel cell manager, for controlling a flow of fuel cell fluids to each of the fuel cell devices. The method discloses: generating electrical power on an electrical bus internal to each of a set of fuel cell devices, which are located in an equipment rack having an external electrical bus; transporting fuel cell fluids from a fluid bus to the fuel cell devices through a fluid manifold; adjusting the electrical power generated by each of the fuel cell devices; and electrically isolating the internal electrical bus of each of the fuel cell devices from the external electrical bus.
