  • Patent number: 12294416
    Abstract: An automobile includes an electronic control unit (ECU), at least one fiber optical cable, and a sensor unit. The ECU is operational to generate an optical power signal and a first optical communications signal. The fiber optical cable transports the optical power signal and the first optical communications signal. The sensor unit is operational to convert the optical power signal into an electrical power, convert the first optical communications signal into an electrical control signal, measure a first parameter related to the automobile, and generate a second optical communications signal that conveys the first parameter as measured. The fiber optical transports the second optical communications signal to the electronic control unit. The ECU is further operational to convert the second optical communications signal into a first electrical sensed signal that conveys the first parameter, and take an action based on the first parameter in the first electrical sensed signal.

  • Patent number: 12290871
    Abstract: Methods and systems for joining multiple workpieces are provided. In one example, the method includes dispensing adhesive on a first workpiece. A second workpiece is contacted with the adhesive such that the adhesive is disposed between the first and second workpieces. Resistance heating is produced in the first and second workpieces at first processing conditions to partially cure the adhesive and affix the first and second workpieces together to form a partially cured, adhesive-joined workpiece assembly. The partially cured, adhesive-joined workpiece assembly is exposed to heat at second processing conditions to substantially fully cure the adhesive.

  • Patent number: 12291121
    Abstract: A system for charging an electric vehicle in a facility includes a current sensor adapted to obtain an input current signal for a power source in the facility. An electric vehicle supply equipment (EVSE) is configured to charge the electric vehicle through the power source based at least partially on a control pilot signal. A controller has a processor and tangible, non-transitory memory on which instructions are recorded for dynamically adjusting the control pilot signal based on the input current signal. The control pilot signal is set to a predefined maximum when the input current signal is less than a main circuit breaker rating of the facility. The controller is configured to reduce the control pilot signal from the predefined maximum when the input current signal is at or above the main circuit breaker rating.

  • Patent number: 12291231
    Abstract: A system for a host vehicle operating on a road surface includes a polarimetric camera, a global positioning system (“GPS”) receiver, a compass, and an electronic control unit (“ECU”). The camera collects polarimetric image data of a drive scene, including a potential driving path on the road surface. The ECU receives the polarimetric image data, estimates the Sun location using the GPS receiver and compass, and computes an ideal representation of the road surface using the Sun location. The ECU normalizes the polarimetric image data such that the road surface has a normalized representation in the drive scene, i.e., an angle of linear polarization (“AoLP”) and degree of linear polarization (“DoLP”) equal predetermined fixed values. The ECU executes a control action using the normalized representation.

  • Patent number: 12291232
    Abstract: A detection system for a host vehicle includes a camera, global positioning system (“GPS”) receiver, compass, and electronic control unit (“ECU”). The camera collects polarimetric image data forming an imaged drive scene inclusive of a road surface illuminated by the Sun. The GPS receiver outputs a present location of the vehicle as a date-and-time-stamped coordinate set. The compass provides a directional heading of the vehicle. The ECU determines the Sun's location relative to the vehicle and camera using an input data set, including the present location and directional heading. The ECU also detects a specular reflecting area or areas on the road surface using the polarimetric image data and Sun's location, with the specular reflecting area(s) forming an output data set. The ECU then executes a control action aboard the host vehicle in response to the output data set.
