  • Patent number: 11984700
    Abstract: A display system includes an integrated laser and modulator device and a display assembly. The integrated laser and modulator device includes a laser component configured to facilitate light emission responsive to applied current and a modulator component configured to selectively modulate light responsive to applied signal. The modulator component is integrally coupled to the laser component via a bridging structure that intervenes between the laser component and the modulator component. At least a portion of the bridging structure facilitates power reflectivity into a laser cavity of the laser component. The bridging structure facilitates transmission of light emitted by the laser component into the modulator component for modulation by the modulator component to provide modulated light. The display assembly is configured to direct the modulated light provided by the integrated laser and modulator device to illuminate pixels to form an image.

  • Publication number: 20240085770
    Abstract: A projection device and an operation method of the projection device are provided. The projection device includes a driver, a LED module, a current sensor, and a controller. The driver generates a driving current signal according to a control signal. The LED module provides an output light beam in response to the driving current signal. The current sensor senses a driving current flowing through the LED module to generate a sensing signal. The controller generates the control signal according to a current calibration parameter and a first control parameter, and determines whether a current value of the driving current flowing through the LED module is in a target driving current value range. When the current value of the driving current is not in the target drive current value range, the controller changes the first control parameter to adjust the control signal.

  • Publication number: 20230245568
    Abstract: A fleet management system coordinates multiple autonomous vehicles (AVs) to transport a group of passengers from one location to another. A single user can submit a request to the fleet management system to provide a ride for the group, the request specifying the number of passengers and the pickup location. The fleet management system determines a number of AVs to transport the group based on the number passengers, and dispatches this number of AVs to the pickup location. The AVs pick up the passengers at the pickup location, drive the passengers to a destination, and drop the passengers off at the destination.
