Abstract: AR glasses are provided with left and right temples extending well behind the ears of the wearer to establish a center of gravity of the glasses that is approximately vertically above the front portion of the ears of the wearer. Rear segments the temples may be detachably engaged with the temples and may hold one or more electrical components.

Abstract: A detection apparatus includes a resonant electrical circuit supported within an interior of a nuclear fuel rod generates a response pulse in response to an excitation pulse and transmits the response pulse through a cladding of the fuel rod to another location within a reactor in which the fuel rod is housed and without any breach in the cladding. A characteristic of the response pulse is indicative of a condition of the fuel rod. The detection apparatus also includes a transmitter positioned outside the cladding, in the reactor, in the vicinity of the fuel rod and configured to generate the excitation pulse and transmit the excitation pulse through the cladding to the resonant electrical circuit. A receiver is supported within the reactor outside of the cladding and, in response to the response pulse, communicates a signal to an electronic processing apparatus outside of the reactor.

Abstract: By using the user head and/or eye tracking capabilities of an extended reality (XR) system, a region of gaze (ROG) of the user towards the virtual screen can be determined and signaled to non-XR games and applications running on the host system connected to the XR system. The existing non-XR games/applications can be patched, upgraded, or remastered to support the application of the ROG and ROG based enhancements of the visuals and user interfaces, using the provided by the system software on the host system that is rendering the game for the XR system.

Abstract: Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). An inter-pupillary distance (IPD) value is determined from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having two fixed optics configured for a specific inter-pupillary distance. The position sensitive device is configured to produce a signal that corresponds to a distance between the two sighting fixtures. The images are warped with a processor to optimize display of the images with the two fixed optics for the determined IPD value.

Abstract: A sunglasses-style head worn display includes a curved waveguide with double reflective coatings/films and containing an array of light wavelength converting phosphor pinhole-size discs covered with pinhole-sized micro lenses, presenting a wide FOV virtual image for AR/VR.

Abstract: Techniques are described for using the Advanced Television Systems Committee (ATSC) 3.0 television protocol to deliver volumetric information for presentation on various displays using ATSC over-the-air communications channels.

Abstract: A volume holographic film (such as a photopolymer) that is pre-recorded with patterns subsequently is used to encode LED or low-power laser light reflections from an eye into a binary pattern that can be read at very high speeds by a relatively simple complementary metal-oxide-semiconductor (CMOS) sensor that may be similar to a high framerate, low resolution mouse sensor. The low-resolution mono images from the film are translated into eye poses using, for instance, a look up table that correlates binary patterns to X, Y positions or using a pre-trained convolutional neural network to robustly interpret many variations of the binary patterns for conversion to X, Y positions.

Abstract: To facilitate control of an AR HMD, a camera unit in a camera sensor system generates RGB/IR images and the system also extrapolates images for times in the future based on light intensity change signals from an event detection sensor (EDS) for HMD pose tracking, hand tracking, and eye tracking. The times in the future are provided by an HMD application which defines the future times, and the RGB/IR images and extrapolated images are sent back to the application. In this way, the camera sensor system enables improved performance tracking (equivalent to using very high-speed camera) at lower bandwidth and power consumption.

Abstract: A stereoscopic VR HMD has left and right display portions in which one of the display portions is arranged with a transformation to improve the perceived virtual image resolution and therefore the perceived virtual image quality. The transformation can include offsetting sub-pixels of one of the display portions in the horizontal and if desired vertical dimensions relative to the other display portion. By applying very small (sub-millimeter) offsets along with appropriately adjusted image data, two slightly different virtual images form a stereoscopic image with a perceived increased of resolution in the binocular overlap zone established by the display portions.

Abstract: A method for gaming. The method includes assigning a default game play profile to a user, wherein the default game play profile includes a default game play style that simulates human game play, and wherein the default game play profile is configured to control game play for the user based on the default game play style. The method includes monitoring a plurality of game plays of the user playing a plurality of gaming applications. The method includes generating a user game play profile of the user by adjusting the default game play style based on the plurality of game plays, wherein the user game play profile incudes a user game play style customized to the user. The method includes controlling an instance of a first gaming application based on the user game play style of the user game play profile.

Abstract: To improve the social interaction and interaction with external objects for a user wearing an AR head-mounted display (HMD), cameras on the HMD detect that other users (“social targets”) are looking at and/or speaking to the user. The region around the social target in the AR user's view is determined and in response an optical occlusion system in the HMD is changed to allow more outside light to reveal the HMD user's eyes to the other users, The HMD optionally decreases the brightness of the virtual images presented in the HMD to allow the HMD user to improve his real world social and scene interaction.

Abstract: A computer game can be viewed on a TV through an augmented reality (AR) head-mounted display (HMD). The wearer can make a gesture such as a first to cause the HMD to present 2D rectangles and 3D objects representing locations in the room that the game can be “presented” in. The wearer may then open his hand and “cast” toward one of the room locations, and the game is transferred to the HMD for presentation in the associated rectangle (in 2D) or 3D object (in 3D).

Abstract: To derive three dimensional (3D) position and orientation of a 3-axis (or more) magnetometer/accelerometer device (such as may be implemented in VR or AR headset or computer game controller) without line of sight constraints, a spinning magnetic field is used to discriminate and remove the external (Earth's) magnetic field from the spinning magnetic field. This reduces the problem to finding the distance to the source of the magnetic field using a calibration table (or formula), finding two angles describing the deviation of the magnetic sensor from the axis of rotation of the spinning magnetic field and the phase around this axis, and from these values deriving the orientation of the sensor.
