There is disclosed a valve assembly for washing cameras or sensors of an autonomous vehicle. The valve assembly includes a single fluid injector having a fluid inlet, a fluid outlet, and a fluid passage in fluid communication with the fluid inlet and the fluid outlet. A cup is disposed over an upstream portion of the fluid injector, relative to a direction of fluid flow through the fluid injector. A lower housing is disposed over and surrounds a downstream portion of the fluid injector, relative to the direction of fluid flow therethrough. A bracket member extends from the lower housing. The bracket member is configured for connecting to an anchor member for attachment within the autonomous vehicle. In this way, the valve assembly may be easily secured within a vehicle for providing a desired amount of fluid to the lens of the vehicle camera or sensor.

Vehicle camera and sensor wash valve assembly

A wireless power transmission method of control is disclosed where equalization of the reactive voltages of a series resonant circuit, which is part of a transmitter antenna tuning and coupling unit, is obtained by adjusting the switching frequency and thereby used to determine a switching frequency of the driving high frequency inverter. By measuring and largely equalizing the voltage parameters of the series resonant circuit to establish an inverter switching frequency, improved efficiency of the wireless power transmission method.

Dynamic tuning using reactive voltages on a series resonator

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.

Reactive power regulation of wireless power transfer network

An RDU fluid injector includes a fluid inlet and a fluid outlet; a fluid path; an actuator unit including a pole piece, a movable armature and a coil; a valve assembly including a valve seat and a seal member connected to the armature and engageable with the valve seat; and a volume reduction member upstream of the actuator unit. The volume reduction member includes a throughbore partly defining the fluid path. The actuator unit, the valve assembly and the volume reduction member are disposed in one or more body portions of the injector, wherein each of the actuator unit, the valve assembly, the volume reduction member and the one or more body portions includes one or more components of the fluid injector. A ratio of a volume of the fluid path to a volume of the components of the fluid injector is between 0.08 and 0.30.

Injector for reductant delivery unit having reduced fluid volume

An injector, including: a moveable armature having a bore and upper and lower control surfaces; a lower housing including a bore and upper and lower stationary control surfaces; and a flow geometry defined along an exterior of the armature. The armature includes a transverse flow path fluidly coupled with the armature bore and the flow geometry. The lower housing includes a transverse flow path fluidly coupled with the lower housing bore. Upon moving the armature from a first position to a second position, a first flow path is formed between the flow geometry and the lower housing transverse flow geometry through a space between the lower stationary control surface and the lower armature control surface, and a second flow path is formed between the armature bore and the lower housing transverse flow geometry through a space between the upper stationary control surface and the armature upper control surface.

High pressure gas phase injector

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.

Using resistance equivalent to estimate temperature of a fuel-injector heater

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 an electronic catalyst or exhaust after-treatment component, wherein the current through the component generates an appropriate loss to generate heat for facilitation of an exhaust after-treatment process. 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.

A method adjusts a pulse width of a signal. The method provides a fixed voltage input trigger pulse (), of a certain pulse width, to a pulse width generator circuit () and provides an output pulse () from the pulse width generator circuit such that a pulse width of the output pulse is longer than the certain pulse width, without changing a voltage or frequency of the input trigger pulse. The method is used to drive an injector of a diesel reductant delivery system to inject fluid into an exhaust flow path.
