Patent number: 11150480Abstract: The disclosed head-mounted display systems may include an optical element supported by a head-mounted display frame, a projector mounted to the head-mounted display frame, and at least one voice coil actuator mounted on the head-mounted display frame. The projector may be configured to project, via the optical element, an image toward an eye of a user of the head-mounted display system. The at least one voice coil actuator may be coupled to at least one of the projector or the optical element. When actuated, the at least one voice coil actuator may translate at least one of the projector or the optical element in at least one direction relative to the head-mounted display frame. Various other methods, systems, and methods of manufacture are also disclosed.Type: GrantFiled: February 20, 2019Date of Patent: October 19, 2021Assignee: Facebook Technologies, LLCInventor: Ryan Michael Ebert

Patent number: 11150459Abstract: A sample observation device includes a light source, an illumination optical system, an observation optical system, a detector, a processor, and a drive controller. The illumination optical system includes a condenser lens and an aperture, and the observation optical system includes an objective lens and a light attenuation member. The light attenuation member and the aperture are conjugate. The aperture includes an aperture region, and the light attenuation member includes a light attenuation region. A size of the aperture region, a position of the aperture region, a size of the light attenuation region, and a position of the light attenuation region are set such that a predetermined state is generated. The processor determines light quantity of light received with the detector. The drive controller changes an interval between a sample and the objective lens on the basis of the light quantity such that the light quantity becomes minimum.Type: GrantFiled: October 10, 2019Date of Patent: October 19, 2021Assignee: OLYMPUS CORPORATIONInventor: Mayumi Odaira

Patent number: 11137612Abstract: A head-mounted device may include a housing structure, a display module mounted in the housing structure, and adjustable support structures coupled to the housing structure. The adjustable support structures may include a first portion that rests against a user's forehead and second and third portions that rest against the user's cheeks or temples. In some arrangements, the adjustable support structures include posts with adjustable lengths, telescoping layers of material, inflatable structures, and/or elastomeric materials that expand and retract to accommodate different face shapes and sizes. In some arrangements, the adjustable support structures include a cable located in a flexible member. When pressure is applied to a forehead portion of the flexible member, the cable pulls the temple portions of the flexible member towards each other. In some arrangements, the adjustable support structures include a movable member that pivots about a pivot axis.Type: GrantFiled: September 5, 2019Date of Patent: October 5, 2021Assignee: Apple Inc.Inventors: Yoonhoo Jo, Thomas E. Degen, Julian Hoenig, Julian Jaede, Aiden D. Mossop, Atif H. Naqvi, Scott Y. Oshita, Heidi Williamson, Edward W. Wong, Timon A. Wright

Patent number: 11130592Abstract: A method of avoiding Controlled Flight Into Terrain (CFIT) involves a step of equipping an aircraft with a radar based sensor positioned in an angular orientation directed forward and down, so as to detect ground objects ahead of the aircraft. The radar must have a range of at least 10 Kilometres. A processing unit monitors the radar 5 based sensor. A display remains in an inactive mode until the radar based sensor detects a ground object meeting predetermined parameters. Upon the radar based sensor detecting a ground object the processing unit is programmed to switch the display to the active mode and display a graphic representation of the ground object. The method puts the pilot on alert with an 10 accentuated and focused warning in sufficient time to take appropriate evasive action to avoid a ground obstacle.Type: GrantFiled: March 26, 2021Date of Patent: September 28, 2021Inventor: Nicky Rosenberg

Patent number: 11134206Abstract: An imaging system includes an image combiner, at least one reflecting mirror, an image generating device and an indication mark. The at least one reflecting mirror is disposed with respect to the image combiner. The image generating device is disposed with respect to the at least one reflecting mirror. When the image generating device displays an image, a light projected by the image generating device is reflected by the at least one reflecting mirror to the image combiner, so as to form a virtual image through the image combiner. The indicating mark is disposed at a periphery of the image combiner.Type: GrantFiled: April 29, 2020Date of Patent: September 28, 2021Assignee: Qisda CorporationInventors: Tsung-Hsun Wu, Wei-Chun Chang
