  • Publication number: 20240404925
    Abstract: A molded power semiconductor package includes a mold compound having first and second opposing main surfaces and an edge between the first and second main surfaces. Power semiconductor dies are embedded in the mold compound. A metallic frame embedded in the mold compound is electrically connected to the power semiconductor dies. Pins protrude from the first main surface of the mold compound, each pin being secured to a respective contact area of the metallic frame that is exposed by an opening in the mold compound at the first main surface. One or more of the openings extends to the edge of the mold compound to form an open channel from each contact area exposed by the one or more of the openings to the edge of the mold compound. Additional package embodiments and methods of production are also described.

  • Publication number: 20240403402
    Abstract: Techniques are disclosed relating to devices that support biometric authentication. In various embodiments, a device includes a biosensor configured to collect biometric data from a user. An authentication system of the device is configured to perform a user authentication based on the collected biometric data. After performance of the user authentication, the authentication system receives sensor data indicating that the user remains collocated with the device and receives a request to confirm an authentication of the user. Based on the user authentication and the received sensor data, the authentication system confirms that the user has been authenticated. In various embodiments, the authentication system is configured to receive additional sensor data indicating that the user is no longer collocated with the device and, in response to a subsequent authentication request, require the user to perform another biometric authentication using the biosensor.

  • Publication number: 20240211569
    Abstract: Methods for performing user authentication based on a multi-representation eye model for devices such as head-mounted display devices are disclosed. The multi-representation eye model may be generated and updated based on feature representations of an identified eye. The user authentication process may be initiated by causing an image to be captured of a current eye under a first set of conditions that may then be transformed into a current feature representation. The current feature representation may be applied to the multi-representation eye model to determine whether the current eye is a match for the identified eye.

  • Patent number: 11861941
    Abstract: Methods and apparatus for using polarized light (e.g., infrared (IR) light) to improve eye-related functions such as iris recognition. An eye camera system includes one or more IR cameras that capture images of the user's eyes that are processed to perform iris recognition, gaze tracking, or other functions. At least one polarizing element may be located in the path of the light which is used to capture images of the user's eye. The user's eye may be illuminated by IR light emitted by one or more LEDs. At least one of the LEDs may be an LED with a polarizing filter. Instead or in addition, at least one polarizer may be located at the eye camera sensor, in the eye camera optics, or as or in an additional optical element located on the light path between the eye camera and the user's eye.

  • Publication number: 20230377302
    Abstract: Methods and apparatus for flexible illumination that improve the performance and robustness of an imaging system are described. Multiple different lighting configurations for the imaging system are pre-generated. Each lighting configuration may specify one or more aspects of lighting. A lookup table may be generated via which each pose is associated with a respective lighting configuration. A user may put on, hold, or otherwise use the device. A process may be initiated in which different lighting configurations may be selected by the controller to capture images of the user's eye, periorbital region, or face at different poses and in different conditions for use by a biometric authentication or gaze tracking process.

  • Publication number: 20230377370
    Abstract: Methods and apparatus for biometric authentication in which two or more cameras are used to capture images of biometric features or aspects for analysis to identify and authenticate a person. An imaging system includes at least two cameras that are used to capture images of a person's iris, eye, periorbital region, and/or other regions of the person's face, and one or more features from the captured images are analyzed to identify and authenticate the person or to detect attempts to spoof the biometric authentication. Information from two or more images may be combined to process aspects and features extracted from the combined images. Alternatively, one of the images to be used for biometric authentication may be determined, for example using one or more objective criteria to evaluate the quality of the captured images.

  • Publication number: 20230379564
    Abstract: Methods and apparatus for biometric authentication in which two or more biometric features or aspects are captured and analyzed individually or in combination to identify and authenticate a person. An imaging system captures images of a person's iris, eye, periorbital region, and/or other regions of the person's face, and two or more features from the captured images are analyzed individually or in combination to identify and authenticate the person and/or to detect attempts to spoof the biometric authentication. Embodiments may improve the performance of biometric authentication systems, and may help to reduce false positives and false negatives by the biometric authentication algorithms.

  • Publication number: 20230367857
    Abstract: Methods and apparatus for biometric authentication in which a current eye pose is determined and evaluated to determine if the current pose is satisfactory, and in which the eye pose may be improved by the user manually adjusting the device or their pose/gaze direction in response to a signal from the controller, and/or in which the imaging system is mechanically adjusted at the direction of the controller to improve the current view of the eye.

  • Publication number: 20230334909
    Abstract: Methods and apparatus for flexible illumination in which two or more different wavelengths are used in the illumination system. An illumination source may be configured to emit light at two or more different wavelengths, either continuously or selectively. A method may be implemented in which a first wavelength is emitted for capturing an image or images for a first portion of algorithmic processing for biometric authentication, and a second wavelength is emitted for capturing another image or images for a second portion of algorithmic processing for biometric authentication. The camera may sequentially capture two or more images at different wavelengths. As an alternative, the camera may be configured to concurrently capture two or more images at different wavelengths.

  • 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.
