Abstract: A wireless power transmission method of control where an electrical parameter of a resonant circuit, which is part of a transmitter antenna tuning and coupling unit, determines in some part the regulation current level target or power level target of the resonant circuit. By using an electrical parameter of a resonant circuit to establish a current or power regulation level of the resonant circuit, a maximum limitation is established for the electrical current and voltage of the antenna tuning and coupling unit in order to operate the electrical elements within safe design limits. Additionally, energy is managed entering the transmitter antenna tuning and coupling unit for variable load at the receiver.

A current-representation signal, which is proportional to an electrical current passing through the heater component is received. A magnified current-representation signal is generated by determining a difference between a current baseline offset, which represents a minimum operating current of the heater component, and the current-representation signal.

Abstract: A dosing valve for administering a reducing agent into an exhaust stream within an exhaust manifold of an internal combustion engine. The dosing valve includes a valve needle internally coaxial to a valve body and held in a closed position by a force of compressed spring acting axially and held in relation to the valve needle and valve body. The negative impact of varnish and dehydrogenated compounds, or coking products, of hydrocarbon based reducing agents, is substantially reduced or eliminated. Additionally, this includes decreased sensitivity to the negative impact of the precipitates and crystals that come out of the solution due to temperature change with urea-based reducing agents.

The heater driver, upon receipt of a turn-on signal, generates a current within a component of a heated fuel injector, wherein the current through the component generates an appropriate loss to generate heat for a variable spray fuel injection system. The heater driver regulates the energy to the heated component based on the electrical resistance of that component as a function of temperature and a predetermined reference value for that temperature.

Abstract: Electrical resistance of a heated component is determined for temperature control and monitoring. A voltage-representation signal, which is proportional to a voltage across a heater component, is received. A current-representation signal, which is proportional to an electrical current passing through the heater component is received and modulated to generate a resistance-representation signal that is proportional to an amount of modulation that makes the current-representation signal approximately equal to the voltage-representation signal. The modulation may be pulse-width modulation. The resistance-representation signal may be generated based on a signal that is proportional to the percent duty cycle of the pulse width modulation. A difference of the resistance-representation signal and the voltage-representation signal may be integrated to provide an error signal adapted to cause the modulation to be proportional to an electrical resistance of the heater component.

Abstract: An air bypass valve (10) includes a solenoid assembly (30) including a magnetic housing (32), a coil bobbin (34) in the magnetic housing, a coil (36) disposed about the coil bobbin, and a magnetic flux ring (38) coupled with the magnetic housing. An armature and seal assembly (12) includes an armature structure (14, 16) that can move with respect to the solenoid assembly from a closed position to an open position in response to a magnetic field generated by the coil. Seal structure (22) is coupled with armature structure so that the seal structure can pivot with respect to the armature structure. The seal structure has a sealing edge (28) to seal with a manifold component when the armature structure is in the closed position thereof. A spring (44) biases the armature structure to the closed position and a main housing covers (46) the magnetic housing.

Abstract: A fuel injector assembly includes a first coil that induces a time varying magnetic field into a second coil that is utilized to heat fuel flowing through the fuel injector. A first coil receives a first signal from a driver to generate a first magnetic field that moves an armature between an open and closed position. The second coil generates a second magnetic field generated by a current induced by the first coil into the second coil. The induced current is generated by an alternating current signal that is interposed onto a direct current signal sent to the first coil. The alternating current signal produces a time varying second magnetic field that induces heating of a magnetically active component with the fuel flow that in turn heats the fuel.
