  • Patent number: 11808841
    Abstract: Systems and methods to perform sensor fusion with a depth imager and a radar system involve transmitting radio frequency (RF) energy from the radar system to a region and simultaneously emitting light to the region using a light source, Reflected light is received at a depth imager aligned with the light source, and RF reflections are received at the radar system. The reflected light is processed to obtain azimuth, elevation, range, variance in range, and reflectivity to each pixel that makes up the region. Processing the RF reflections provides azimuth, elevation, range, variance in range, velocity, and variance in velocity to a subset of the pixels representing a region of interest. Performing the sensor fusion includes using the azimuth, the elevation, the variance in range, and the reflectivity resulting from the depth imager and the range, the velocity, and the variance in velocity resulting from the radar system.

  • Patent number: 11808599
    Abstract: A route recording with real-time annotation and re-display system includes a first automobile vehicle having one or more camera systems. An imaging display device defining a head-up display (HUD) is positioned within the first automobile vehicle and receives camera imaging data from the one or more camera systems. The HUD includes a video display screen presenting the camera imaging data either in real-time or re-displayed from a pre-recorded image file. A microphone array receives vehicle operator voice data of a first operator of the first automobile vehicle. An annotated-recorded-route is created by adding a user input of the first operator of the first automobile vehicle including the voice data. The annotated-recorded-route identifies specific coordinates or locations along a travel route driven by the automobile vehicle through the voice data after activating recording of the camera imaging data.

  • Patent number: 11811187
    Abstract: A non-reciprocal optical assembly for injection locking a laser to a resonator is described. The laser emits a light beam, and the resonator receives the light beam and returns a feedback light beam to the laser such that the feedback light beam causes injection locking. The non-reciprocal optical assembly is interposed between and optically coupled to the laser and the resonator. The non-reciprocal optical assembly includes a first port that receives the light beam from the laser, and a second port that outputs the light beam to the resonator and receives the feedback light beam from the resonator. The first port also outputs the feedback light beam to the laser. The light beam passes through the non-reciprocal optical assembly with a first power loss, and the feedback light beam passes through the non-reciprocal optical assembly with a second power loss (the first power loss differs from the second power loss).

  • Patent number: 11807090
    Abstract: A test system for detecting impairment aboard a motor vehicle includes an electronic control unit (ECU) and sensors in communication therewith. The sensors are positioned within a vehicle interior, and include at least a touch screen and a microphone, and possibly an eye-tracking camera. In response to receiving a start request indicative of a requested start event of the motor vehicle, the ECU executes instructions to initiate a cognitive response test via the sensors. The ECU determines a test score of a driver during the test while the motor vehicle remains off, compares the test score to baseline scores to determine a passing or failing test result, and executes a control action aboard the motor vehicle in response to the passing or failing test result. The ECU may disable or immobilize the motor vehicle in response to the failing test result.

  • Publication number: 20230347777
    Abstract: Presented are intelligent vehicle systems and logic for battery charge control and information display, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a vehicle includes a vehicle controller receiving vehicle location data indicating a real-time location of the vehicle and determining if the vehicle's real-time location is within a virtual geofence that delineates a predefined geographic area. If the real-time vehicle location is within the virtual geofence, the controller receives user location data indicating a real-time location of a vehicle user and determines if the user's real-time location is within a predefined proximity to the vehicle. If the user is within the predefined proximity to the vehicle, the controller responsively determines if a vehicle battery is charging; if so, the controller transmits a command signal to a resident vehicle subsystem to execute a control operation related to the charging of the vehicle battery.
