Abstract: The packer system includes a packer mandrel, an upper support or gage ring, a seal member, an upper slip device, an upper cone, a lower cone, a lower slip device, a setting sleeve, and a setting piston. The seal member has a run-in position and a set position. The set position seals against a borehole at a location in a borehole. The setting sleeve has a bypass position to transfer load of the setting piston away from the lower slip device and to the lower cone, the seal member, and the upper cone to set the seal member and upper slip device before the lower slip device. The setting sleeve has a released position to separate from the setting piston so that the load of the setting piston can finally be applied on the lower slip device for expansion of the lower slip device at the proper time and location.

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

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.

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.

Abstract: A temperature of a heated component is determined for control and monitoring. 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.

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.
