Patent number: 11814016Abstract: 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.Type: GrantFiled: July 3, 2019Date of Patent: November 14, 2023Inventors: Douglas Edward Cosby, Stephen C Bugos, Michael J.

Patent number: 11349341Abstract: 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.Type: GrantFiled: November 22, 2019Date of Patent: May 31, 2022Assignee: Vitesco Technologies USA, LLCInventors: Perry Robert Czimmek, Willem Nicolaas Van Vuuren, Douglas Edward Cosby

Patent number: 11316373Abstract: 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.Type: GrantFiled: November 22, 2019Date of Patent: April 26, 2022Assignee: Vitesco Technologies USA, LLCInventors: Perry Robert Czimmek, Douglas Edward Cosby
