Abstract: There is provided a method and system for determining if a head-mounted device for extended reality (XR) is correctly positioned on a user, and optionally performing a position correction procedure if the head-mounted device is determined to be incorrectly positioned on the user. Embodiments include: performing eye tracking by estimating, based on a first image of a first eye of the user, a position of a pupil in two dimensions; determining whether the estimated position of the pupil of the first eye is within a predetermined allowable area in the first image; and, if the determined position of the pupil of the first eye is inside the predetermined allowable area, concluding that the head-mounted device is correctly positioned on the user; or, if the determined position of the pupil of the first eye is outside the predetermined allowable area, concluding that the head-mounted device is incorrectly positioned on the user.

Abstract: A camera identification method comprises identifying a to-be-identified camera using a light sensitivity deviation of each pixel in the to-be-identified camera; generating corresponding identification data; identifying a target camera using a light sensitivity deviation of each pixel in the target camera; and identifying the target camera by comparing a similarity between data that identifies the target camera and identification data of a known camera.

Abstract: Systems, apparatuses, and methods for utilizing different modulation coding schemes (MCSs) for different components of a video stream are disclosed. A system includes a transmitter sending a video stream over a wireless link to a receiver. The transmitter splits the video stream into low, medium, and high quality components, and then the transmitter modulates the different components using different MCS's. For example, the transmitter modulates the low quality component using a lower, robust MCS level to increase the likelihood that this component is received. Also, the medium quality component is modulated using a medium MCS level and the high frequency component is modulated using a higher MCS level. If only the low quality component is received by the receiver, then the receiver reconstructs and displays a low quality video frame from this component, which avoids a glitch in the display of the video stream.

Abstract: Aspects of the disclosure provide for an apparatus. In some examples, the apparatus includes a clock generator, a clock data recovery (CDR) circuit, a state machine, and an adder. The clock generator is configured to determine a sampling clock based on a received input clock and a clock offset. The CDR circuit is configured to determine a phase of the input clock and determine CDR codes based on the determined phase and sampled data. The state machine is configured to record a first CDR code of the CDR codes at a first time, record a second CDR code of the CDR codes at a second time subsequent to the first time, and determine a calibrated offset based on the first CDR code and the second CDR code. The adder is configured to determine the clock offset according to the CDR codes and the calibrated offset.

Abstract: In an example there is provided a method for a set of registered devices that are registered to participate in an authentication protocol, where each registered device has a share of an authentication key. The method comprises generating share data for a share of the authentication key. The share data is communicated from an authorised subset of the registered devices to a device. The share of the authentication key is generated at the device, on the basis of the share data. The share of the authentication key combines with shares of the registered devices to allow the device to participate in the authentication protocol.

Abstract: A radar authentication method includes after obtaining output data of a to-be-authenticated radar, a computer device that first invokes a prediction model to obtain predicted data of the to-be-authenticated radar based on the output data of the to-be-authenticated radar, where the prediction model is obtained through training based on output data of a target radar. Then the computer device verifies, based on the predicted data of the to-be-authenticated radar and the output data of the to-be-authenticated radar, whether the to-be-authenticated radar and the target radar are the same radar.

Abstract: Images of an eye are captured by a camera. For each of the images, gaze data is obtained and a position of a pupil center is estimated in the image. The gaze data indicates a gaze point and/or gaze direction of the eye when the image was captured. A mapping is calibrated using the obtained gaze data and the estimated positions of the pupil center. The mapping maps positions of the pupil center in images captured by the camera to gaze points at a surface, or to gaze directions. A further image of the eye is captured by the camera. A position of the pupil center is estimated in the further image. Gaze tracking is performed using the calibrated mapping and the estimated position of the pupil center in the further image. These steps may for example be performed at a HMD.

Abstract: A load controller in a load control system may communicate messages with controllable loads on a plurality of loops for controlling electrical loads. Each controllable load may include a load control device and an associated electrical load. The messages received by the load controller may include a zone identifier. The zone identifier may be associated with the load control devices for being controlled together. The load controller may communicate messages to sets of load control devices for performing common control of the load control devices on each loop using group messages. The load controller may reconfigure the zones that are assigned group identifiers for receiving group messages on the loops, such that the group identifiers are assigned to the zones that have larger numbers of load control devices. The message types on a given loop may be selected based on the type of control being transmitted in the commands.

Abstract: An eye tracking system is provided that detects the presence of problematic blobs in an image captured by the system and removes these problematic blobs by switching off illuminators. Problematic blobs may be those obscuring the pupil of the eye of the user. Each blob is detected in a first image by the use of at least one first criterion, and then an illuminator is switched off. After the illuminator is switched off, at least one second criterion is used to identify blobs in a subsequent image. This process may be repeated until the illuminator causing the problematic blob is identified.

Abstract: An automated wire feeder assembly to first repetitively receive a wire from a gripper of an automated processing tool and then load the wire into a hollow conduit coupled to the gripper of the automated tool. The wire feeder assembly includes belts that pivot between open and closed positions and each belt rotate to advance a wire into the conduit attached to the gripper of the automated tool. When the belts are in the open position the gripper of the automated tool places a free end of the wire into a wire guide. Pivoting the belts to the closed position engages the belts with the free end of the wire. Once the belt is engaged with the free end of the wire, rotating the belts advances the wire out of the wire feeder and into the gripper conduit.

Abstract: Images of an eye are captured at respective time instances by a camera of a head-mounted device. For each time instance, a position of a center of corneal curvature is estimated using an image captured at that time instance, a position of a pupil center is estimated using an image captured at that time instance, and a line is determined through the estimated corneal curvature center position and the estimated pupil center position. A first estimated position of a center of the eye is computed based on the lines determined for time instances in a first time period. A second estimated position of the center of the eye is computed based on the lines determined for time instances in a second time period. Relocation of the head-mounted device relative to a user's head is detected based on the first and second estimated positions of the eye center.

Abstract: A system and method optimizes game quality by matching players for an online game to one of several virtual games. This matching process may involve filtering the players who wish to play according to various constraint minimizing criteria, packing the players into one or more virtual games to optimize game quality factors of the virtual games, and then instantiating the virtual games to actual online games played by the players. The game packing process may be iterative and may involve adding a new player into a virtual game. Game quality factor (GQF) values prior to and after the placement of the new player in the virtual game may be compared. The comparison of the GQF values may be used, at least in part to determine whether the new player is to remain in the virtual game. Various criteria may be considered in instantiating a virtual game.
