Patent number: 10914953Abstract: A tunable waveguide display includes a source waveguide, a first tunable lens (FTL), an output waveguide, and a second tunable lens (STL). The source waveguide receives light, expands the light in a first dimension, and outputs the expanded light. The FTL adjusts a wavefront of the expanded light to form adjusted light. The output waveguide receives the adjusted light, expands the adjusted light in a second dimension to form image light, and outputs the image light. The STL adjusts a wavefront of the image light. The FTL and the STL control an image plane of the image light.Type: GrantFiled: June 11, 2018Date of Patent: February 9, 2021Assignee: Facebook Technologies, LLCInventors: Wai Sze Tiffany Lam, Yijing Fu, Lu Lu, Pasi Saarikko

Patent number: 10914435Abstract: A modular light system comprising a lightbar assembly with first and second conductive parts, each of which extend in a direction generally transverse to a longitudinal axis of the lightbar assembly. The modular lightbar system further comprises a lightbar assembly connector having a major surface and with a conductive part that extends in a direction generally transverse to the major surface. Such a design and configuration enables the lightbar assembly connector and lightbar assembly to be connected by moving the lightbar assembly connector in a direction generally transverse to the longitudinal axis of the lightbar assembly (or by moving the lightbar assembly in a direction generally transverse to the major surface of the lightbar assembly connector). It is thus possible to assemble a lightbar system comprised of a plurality of lightbar assemblies and lightbar assembly connectors, any of which are removable, replaceable, or serviceable.Type: GrantFiled: June 5, 2020Date of Patent: February 9, 2021Assignee: MAXLITE, INC.Inventors: Aymen Chami, Yaolin Tang

Patent number: 10732340Abstract: Techniques of providing illumination to a head-mounted display (HMD) involve providing off-board illumination apart from the HMD. An off-board illumination unit delivers the illumination to the HMD via optical fibers. The optical fibers are lightweight and do not restrict motion of a user. Because the power source is less restricted, the off-board illumination unit provides flexibility in the hardware used to generate the illumination. For example, the illumination unit may use red, green, and blue narrow-band diode lasers. Further, by controlling modes in the fiber and providing additional light-guiding hardware, the angles at which light strikes LCD pixels may be largely restricted to certain specified angles. Restricted angles of incidence enable the use of fast-switching liquid crystals without degrading the image quality. Such a restriction allows for high-resolution imaging using rapid switching of the liquid crystal which enables very low latencies.Type: GrantFiled: July 21, 2017Date of Patent: August 4, 2020Assignee: GOOGLE LLCInventors: Martin Friedrich Schubert, Michael Grundmann

Patent number: 10731811Abstract: The invention relates to the field of illumination technology and provides a simulated candle tip, which comprises a light source arranged in the flame base such that a light emitted by the light source can be projected through the reflecting chamber of the flame cover, to simulate real flames. By controlling the power on/off of the electromagnetic coil and the direction of current, attracting and repelling forces can be generated between the electromagnetic coil and the magnet, to enable the flame holder to perform regular swing motion in forward, backward, left and right directions. In this way, both the light source disposed at the upper end of the flame holder and the flame cover can perform swing motion along with the flame holder, to simulate flickering effect of real burning flames. In such case, a stable swing motion can be realized, and it is easy to control.Type: GrantFiled: September 12, 2019Date of Patent: August 4, 2020Assignee: AE TECHNOLOGIES CO., LTD.Inventor: Wenfeng Wu
