Patent number: 11767929Abstract: An assembly includes an inlet tube. The assembly includes a first outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube. The solenoid assembly has a spring urging the plunger to the closed position. The solenoid assembly has a strain gage fixed to the spring. A strain detected by the strain gage indicates whether the plunger is at the closed position.Type: GrantFiled: March 26, 2021Date of Patent: September 26, 2023Assignees: Ford Global Technologies, LLC, Valeo North America, Inc.Inventors: Segundo Baldovino, Ashwin Arunmozhi, Venkatesh Krishnan, Charles Prain, Michael Whitney, William S.

Patent number: 11745703Abstract: An assembly includes an inlet tube and an outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube. The solenoid assembly has a spring urging the plunger to the closed position. The assembly includes a first pressure sensor positioned to be compressed when the plunger is moved toward the open position. Pressure detected by the first pressure sensor indicates whether the plunger is at the open position. The assembly includes a second pressure sensor positioned to be compressed when the plunger is moved toward the closed position. Pressure detected by the second pressure sensor indicates whether the plunger is at the closed position.Type: GrantFiled: March 23, 2021Date of Patent: September 5, 2023Assignees: Ford Global Technologies, LLC, Valeo North America, Inc.Inventors: Venkatesh Krishnan, Segundo Baldovino, Ashwin Arunmozhi, Charles Prain, Michael Whitney, William S.

Publication number: 20220307619Abstract: An assembly includes an inlet tube and an outlet tube. The assembly includes a solenoid assembly having a plunger movable between an open position in which fluid is permitted to flow from the inlet tube to the outlet tube and a closed position in which fluid is inhibited from flowing from the inlet tube to the outlet tube, the solenoid assembly having an induction coil surrounding the plunger. The assembly includes a Hall effect sensor that detects a magnetic field of the solenoid assembly. The assembly includes a computer in communication with the Hall effect sensor, the computer having a processor and memory that stores instructions executable by the processor to identify a resistance of the induction coil based on data from the Hall effect sensor, and to determine whether the plunger is at the closed position based on the identified resistance of the induction coil.Type: ApplicationFiled: March 23, 2021Publication date: September 29, 2022Applicants: Ford Global Technologies, LLC, Valeo North America, Inc.Inventors: Segundo Baldovino, Venkatesh Krishnan, Ashwin Arunmozhi, Charles Prain, Michael Whitney, William S.

Patent number: 10946838Abstract: A sensor apparatus includes a cylindrical sensor window defining an axis, and a tubular annular member fixed relative to the sensor window and substantially centered around the axis. The annular member includes a plurality of first nozzles and second nozzles arranged in an alternating pattern around the annular member. The first nozzles each have a direction of discharge in a radially inward and axial direction forming a first angle with the axis. The second nozzles each have a direction of discharge in a radially inward and axial direction forming a second angle with the axis, and the second angle is different than the first angle.Type: GrantFiled: March 21, 2019Date of Patent: March 16, 2021Assignee: Ford Global Technologies, LLCInventors: Andre Sykula, Venkatesh Krishnan, Segundo Baldovino, Michael Whitney, David Franco, Maxime Baudouin, Xavier Bousset, William Terrasse, Theophile Jullien, Geoffroy Duplaix
