Patent number: 11558024Abstract: Disclosed is a device for filtering electrical noise in a vehicle. The device includes a housing connectable to the vehicle, a variable capacitor, an input signal line coupled to the variable capacitor and couplable to a first conductor that carries electrical signals along with electrical noise of a given amplitude, and an output signal line coupled to the variable capacitor and couplable to a second conductor. When the input signal line is coupled to the first conductor and the output signal line is coupled to the second conductor, the second conductor carries the electrical signals along with electrical noise of reduced amplitude within a range of frequencies. The device also includes a tuner coupled to the housing and configured to adjust a capacitance of the variable capacitor, wherein adjusting the capacitance of the variable capacitor adjusts the range of frequencies.Type: GrantFiled: April 9, 2020Date of Patent: January 17, 2023Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventors: Ming M.

Patent number: 11042765Abstract: In one embodiment, a safety system for playing vehicle monitored content in a vehicle while minimizing driver distraction is provided. When the driver selects a camera, such as a rear view camera, vehicle monitored content stream from the camera is displayed on a display in the vehicle. While the driver drives the vehicle, the eye-gaze of the driver is monitored. When the eye-gaze of the driver shows that the driver is looking at the display, a timer is started. The timer runs when the driver looks at the display. When the eye-gaze of the driver shows that the driver has looked at the road continuously for more than a threshold amount of time, the time associated with the vehicle monitored content is reset back to its initial value. If the timer runs out, indicating that the driver has been watching the vehicle monitored content too much without also looking at the road, the vehicle monitored content is stopped and the driver is prevented from watching the vehicle monitored content for some period of time.Type: GrantFiled: May 14, 2019Date of Patent: June 22, 2021Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Coh L.

Patent number: 10796177Abstract: A safety system can play videos in a vehicle while minimizing driver distraction. The driver can select a video source, and video from the video source may begin playing on a display to the driver. Upon the driver first selecting the video, the video is displayed to the driver for an amount of time that does not exceed a timer having a duration. If the driver again selects to view the video, the duration associated with the timer is reduced, and the video is displayed for an amount of time that does not exceed the newly reduced timer. As the driver continues to try to view the video, the duration of the timer is further reduced until it is zero or near zero. After which the driver may not be permitted to view the video until a threshold amount of time has passed.Type: GrantFiled: May 15, 2019Date of Patent: October 6, 2020Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Coh L.
