A wireless power receiver configured to control an electrical connection between a capture resonator of a wireless power transfer system and an electrical load, such as a battery pack or electric motor. The circuitry of the wireless power receiver is powered directly by the power output from the capture resonator, automatically powering up the wireless power receiver as soon as the capture resonator begins producing power. The wireless power receiverdoes not require stand-by power provided by an external source, such as a vehicle battery. Since the wireless power receiver does not require power from an external source, it can initiate charging of a vehicle battery even if the state of charge of the battery in the vehicle is too low to operate the controller.

Magnetic field detection apparatus for a wireless power transfer system

A system for managing regeneration of a CDPF in a diesel engine. The system determines volatility of the accumulated soot by a weighting/indexing method to select a regeneration control strategy that protects the CDPF from thermal damage. The system determines the mass of wet soot and dry soot accumulated over the previous driving cycle and selects a management strategy to control the rate of temperature increase and the thermal gradient imposed upon the filter. The wet soot percent is an index for setting the regeneration temperature control profile for an allowable total accumulated soot mass as a function of the accumulated wet soot. The method also scales the soot mass regeneration threshold value based upon wet soot accumulation and accumulation rate and provides an indicator of combustibility of the soot accumulation. The method provides a temperature ramp rate, total regeneration time, and exhaust oxygen level required to control regeneration.

A method for triggering a new regeneration event in a soot-trapping particulates filter disposed in an exhaust gas stream of an internal combustion engine, comprising the steps of determining instantaneous engine speed and engine load; determining instantaneous mass fractions for wet soot and for dry soot in the exhaust gas stream for the instantaneous engine speed and load; determining instantaneous concentrations of wet and dry soot particles in the exhaust gas; determining the rates of accumulation of wet soot and dry soot in the particulates filter; determining the total amounts of wet soot and dry soot accumulated in said soot-trapping device during all engine operation conditions since the latest previous regeneration event; and triggering the new regeneration event when the total amount of wet soot and dry soot exceeds a permissible value.

A fuel cell APU system comprising a plurality of fuel cell modules connected in parallel. Each module includes a local controller connected to a master controller that coordinates the modules to achieve a desired power output at any given time. Each module is operated within an output range to maximize efficiency of the system. When load demand on a first module exceeds the desired output range of the module, an additional module is brought online in parallel with the first. As the load increases further, additional modules are brought online in cascade fashion to permit all modules to be operated efficiently. If a module is disabled, it is automatically switched out of service and replaced by a standby module. The master controller keeps track of the total operating time of each module and varies the sequence in which different modules are brought into service to balance deterioration among the modules.
