  • Patent number: 11640017
    Abstract: Apparatuses, methods, and systems are taught that convey information in a mirror to a user. A glass layer has a front side and a back side. The glass layer further includes a first region. The first region has a first optical property. A second region has a second optical property. The first optical property is different than the second optical property. A first boundary exists where the first region meets the second region and the first boundary is shaped to convey information when the second region is illuminated from the back side and the glass layer is viewed from the front side by the user. When the second region is not illuminated from the back side the first region and the second region provide substantially the same reflection when the glass layer is viewed from the front side by the user, and the first boundary does not convey information.

  • Patent number: 11613201
    Abstract: In various examples, high beam control for vehicles may be automated using a deep neural network (DNN) that processes sensor data received from vehicle sensors. The DNN may process the sensor data to output pixel-level semantic segmentation masks in order to differentiate actionable objects (e.g., vehicles with front or back lights lit, bicyclists, or pedestrians) from other objects (e.g., parked vehicles). Resulting segmentation masks output by the DNN(s), when combined with one or more post processing steps, may be used to generate masks for automated high beam on/off activation and/or dimming or shading—thereby providing additional illumination of an environment for the driver while controlling downstream effects of high beam glare for active vehicles.

  • Patent number: 11602033
    Abstract: The present disclosure describes a network device that is capable of coordinating the control of light emitters. For example, the network device may receive data indicating conditions for activating the light emitters. The network device may then receive sensor data generated by various sensors, such as motion sensors, light sensors, or a timer. Using the sensor data, the network device may determine that the conditions are satisfied and, in response, cause the light emitters to activate. To activate first light emitters, the network device may transmit a signal to an electronic device that causes the first light emitters to activate. The first light emitters may be powered by the electronic device. Additionally, to activate second light emitters, the network device may transmit signals to the second light emitters that include commands to activate.
