Abstract: A display apparatus includes a substrate, a pixel arranged in a display area of the substrate and including a light-emitting diode configured to emit light in a first mode, and a photo sensor arranged in the display area of the substrate and configured to receive, in a second mode, light reflected from an external object and receive external light in a third mode. The first mode is triggered by a signal to display an image, the second mode is triggered by reflection from the external object, and the third mode is triggered by absence of the signal to display an image and reflection from the external object.

Abstract: A biometric button assembly may be disposed in an opening of an enclosure of an electronic device. The biometric button assembly may include an input member that forms an exterior surface of the button housing and is configured to receive inputs, for example from a user of the electronic device. The biometric button assembly may further include a biometric sensor for detecting the received inputs and transmitting a signal to a processor of the electronic device. The signal may correspond to a biometric characteristic, such as a fingerprint. A flexible conduit may transmit the signal to the processor. A portion of the flexible conduit and a seal may be positioned between the button assembly and the enclosure that prevents contaminants from entering the button housing and the enclosure.

Abstract: In various examples, infrared image data may be used to detect a subcutaneous characteristic(s) (e.g., a palm vein topology) of a person (e.g., a person requesting entry to a vehicle, a vehicle occupant) and authenticate the user based on the detected subcutaneous characteristic(s). For example, infrared image data representing one or more acquired subcutaneous characteristics (e.g., a topology of veins and/or other blood vessels in a region of the authenticating user's palm, hand, neck, forearm, face, fingertip, eye, etc.) may be generated. Hand and/or palm detection may be applied to detect a region depicting the user's hand or palm, and that region (or some subset thereof) may be segmented to generate a representation of an acquired vein topology. The acquired vein topology may be compared with one or more reference vein topologies stored in a database to determine whether the acquired vein topology matches one of the reference vein topologies.
