Patent number: 11163402Abstract: Systems and methods for determining a likelihood of an occurrence of an anomaly in a sensor are described. A processor can receive a first measurement of a first capacitance change between a first port and a second port of a device connected to the sensor. The first measurement can be obtained in response to the first port being configured to perform a first function, and in response to the second port being configured to perform a second function. The processor can receive a second measurement of a second capacitance change between the first and second ports. The second measurement can be obtained in response to the first port being configured to perform the second function, and in response to the second port being configured to perform the first function. The processor can determine the likelihood of the occurrence of the anomaly based on the first and second measurements.Type: GrantFiled: March 29, 2021Date of Patent: November 2, 2021Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Christopher Semanson, Onkar Raut, James Page

Patent number: 10364735Abstract: Methods and systems are provided for adjusting vehicle grille shutters based on a direction of motion of the grille shutters. In one example, a method includes adjusting a motor coupled to the grille shutters based on the direction of motion of the grille shutters, a desired opening of the grille shutters, and vehicle speed. Further, the method may include determining the direction of motion of the grille shutters based on a desired motor position relative to an actual motor position.Type: GrantFiled: November 27, 2013Date of Patent: July 30, 2019Assignee: Ford Global Technologies, LLCInventors: Kevin Macfarlane, Christopher Semanson, Joseph James Gallo, Mark Fleming, Colby Jason Buckman, Robert Roy Jentz

Patent number: 10093198Abstract: A method is provided for determining a lower voltage set-point, an upper voltage set-point, a temperature-dependent upper current set-point, a time limit value, and a lower current hysteresis threshold set-point based on a measured temperature of a battery. A charge current from a battery charging circuit is provided. If a charge voltage is above the lower voltage set-point and below the upper voltage set-point and the charge current exceeds the temperature-dependent upper current set-point, timer is started. If the timer reaches a time limit value while the charge current exceeds the temperature-dependent upper current set-point and the charge voltage is between the lower voltage set-point and the upper voltage set-point, the charge current is reduced.Type: GrantFiled: August 24, 2017Date of Patent: October 9, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Cathleen Tistle, Mark Eifert, Christopher Semanson

Patent number: 9988954Abstract: Methods and systems are provided for filtering an oil dilution amount based on a current value of the oil dilution amount. In one example, filtering the oil dilution amount may include decreasing a sensitivity of filtering at lower oil dilution below a threshold; otherwise, increasing the sensitivity of filtering. The sensitivity of the filtering may be decreased by implementing a larger time constant, while the sensitivity of the filtering may be increased by implementing a smaller time constant.Type: GrantFiled: June 30, 2016Date of Patent: June 5, 2018Assignee: Ford Global Technologies, LLCInventors: Kevin Macfarlane, Dennis Witt, Amanda Perkins, Christopher Semanson, Robert Milton, Charles Irwin Rackmil
