  • Patent number: 12252898
    Abstract: The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.

  • Patent number: 12123218
    Abstract: The present invention relates to a variable friction energy dissipation prefabricated seismic-damping partition wall-frame structure and a construction method therefor. The variable friction energy dissipation prefabricated seismic-damping partition wall-frame structure includes a peripheral frame, prefabricated seismic-damping partition wall panels, rubber pads, a friction seismic-damping layer, horizontal force transfer members and a steel angle restraining members. The sliding friction of the partition wall can be significantly improved with increase of an inter-story drift, so that the partition wall has a larger hysteretic area and a higher energy dissipation capacity and can provide the structure with a relatively high additional damping ratio, so as to alleviate a seismic action. In addition, integral damage control of the partition wall can be better achieved, and the energy dissipation capacity of the partition wall under bidirectional seismic actions can be guaranteed.

  • Publication number: 20240272709
    Abstract: Methods and apparatus for generating user-aware eye models. During an enrollment process, images of a user's eye are captured by one or more cameras when the eye is in two or more different orientations and at two or more different levels of display brightness. The captured images are processed to generate a 3-dimensional, user-aware eye model, for example a model of at least the eye's cornea and pupil features. The generated user-aware eye model may be used in other processes, for example in a gaze tracking process. The enrollment process may be an iterative process to optimize the eye model, or a continuous process performed while the user is using the system.

  • Publication number: 20240211038
    Abstract: Methods to trigger eye enrollment without requiring good gaze interaction are described that allow a guest user of a device to initiate partial or full eye enrollment even though their eye model is not known and thus conventional gaze-based interactions do not work well. A gaze tracking system collects gaze data in the background. At any time (or within an interval after a user puts on the device), an eye enrollment can be triggered by detecting some gaze gesture, for example rolling the eyes in a large circle, or moving the eyes randomly for a time that exceeds a threshold. Depending on the coverage of the gaze/cornea data collected in the background, a full eye enrollment or only a visual axis enrollment may be performed in response to the gesture.

  • Publication number: 20240211039
    Abstract: In an unobtrusive visual axis enrollment process, a line of text or other content is displayed at a known vertical location and virtual depth that the user can then read. This line of text may be content that the user needs to read as part of the normal enrollment process. As the user reads the line of text, eye tracking cameras may capture images of the eye. This data may then be used to estimate a stimulus plane. The error between the estimated stimulus plane and the ground truth stimulus plane (the actual location of the line of text in virtual space) may then be used to estimate the kappa angle.

  • Publication number: 20240104967
    Abstract: A personalized eye model is used to generate synthetic gaze features at ground-truth eye poses Gg. Corresponding synthetic gaze poses Gs are estimated from the synthetic gaze features using an average eye model. A linear regression is applied between Gg and Gs to generate a gaze correction function. The gaze correction function represents differences between the synthetic gaze Gs of the subject eye at the display and that of the average eye model Gg at the display, but does not contain security- or privacy-sensitive information. Further, the personalized eye model cannot be recovered from the gaze correction function, and thus the gaze correction function can be stored unencrypted and available for use during a cold boot of a device prior to login. On a cold boot of the device, the gaze correction function may be accessed and used with an average eye model to improve gaze-based interactions.

  • Publication number: 20240104958
    Abstract: Methods and apparatus for providing eye model matching in a device are disclosed. When a user activates a device and the presence of the user's eye is detected, an image of the user's eye is captured. An eye model matching process is then implemented to determine a stored eye model (e.g., an eye model stored after enrollment of the eye on the device) that best matches the eye in the captured image. Determination of the best matching eye model may be based on matching between properties of the user's eye in the captured image (such as cornea and pupil features) and properties of the user's eye determined by the eye model. The best matching eye model may then be implemented in, for example, an eye gaze tracking process. In certain instances, the best matching eye model satisfies a threshold for matching before being implemented in the downstream process.

  • Publication number: 20230315201
    Abstract: Methods and apparatus for stray light mitigation in optical systems that include two or more illumination sources (e.g., point light sources such as light-emitting diodes (LEDs)) that illuminate an object to be imaged, and a camera configured to capture images of light from the point light sources reflected by the object when illuminated. To mitigate “occlusions” or artifacts caused by, for example, stray light or reflections of the illumination sources off of other components of the system, multiple images of the object are captured with different groups of the illumination sources enabled. The captured images can then be processed and merged to generate an output image with the occlusions or artifacts caused by stray light or reflections mitigated or eliminated.
