  • Patent number: 11977230
    Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

  • Patent number: 11914150
    Abstract: A wearable display system includes a light projection system having one or more emissive microdisplays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.

  • Patent number: 11204143
    Abstract: A solar disk light has a central body and an annular shelf surrounding the central body and attached to the central body by one or more struts, defining a gap between an inner surface of the annular shelf and the central body. LEDs are disposed on the annular shelf. The central body has solar cells for harvesting solar energy and detecting ambient light. The central body contains a rechargeable battery for storing harvested solar energy, a switch, and wiring and driver electronics for operably connecting the solar cells, battery, switch, and LEDs. A translucent shell is on the disk light body, covering the annular shelf and LEDs, such that light emitted by the LEDs shines through the shell. The shell has an opening for receiving the central body such that the solar cells are not covered by the shell, the shell having an inner wall received in the gap.

  • Patent number: 9362852
    Abstract: The current disclosure teaches and describes a generator assembly and related hand crank devices. One embodiment of the device may include a traditional generator, a handle and a crank link. The crank link is rotatably connected to the handle in a perpendicular position. A user may hold the handle and wield the hand crank device to make the crank link rotate around the handle like a clock hand, enabling the generator to provide power to the hand crank device. Such wielding motion may also be driven by other forces. The current design allows the user to charge the device with only one hand and with ease. In addition, the “functioning” components of the current hand crank device may be housed in or attached to either the handle or crank link, or both. Other components may also be introduced to make the generator assembly more efficient and easy to use.

  • Patent number: 8612165
    Abstract: The invention relates to a method and system for determining an aerodynamic drag area CxA of a moving vehicle, for example a bicycle, in dependence upon the airflow yaw direction and speed without the use of a wind tunnel. The vehicle is equipped with sensors for collecting time-stamped values indicative of the vehicle speed, propulsion force, airflow speed and yaw angle of the airflow at various points during the trip. The trip data are then processed using successively refined hypotheses regarding the CxA(yaw) dependence to generate a plurality of elevation profiles for the travelled path. The generated elevation profiles are then evaluated based on available route elevation information to select a correct dependence of the aerodynamic drag area upon the yaw angle of the airflow.

  • Publication number: 20100153482
    Abstract: In an example embodiment, workflow based procedures are authored, tested and converted to a collection of resource automation scripts with orchestration rules. The scripts and rules are uploaded to a cloud-based provisioning service. The cloud-based provisioning service follows the orchestration rules to coordinate with a provisioning agent installed on a VM host, storage area network (SAN) or other network device to execute a sequence of scripts to provision or tear down resources.
