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.

Abstract: Electronic devices such as head-mounted electronic devices may include displays for presenting images to users. To accommodate variations in the interpupillary distances associated with different users, a head-mounted device may have left-eye and right-eye optical modules that move with respect to each other. To hide internal structures from view, the rear of a head-mounted device may be provided with a cover. The cover may have a stretchable layer that is coupled to a frame. Openings in the stretchable layer may be aligned with the optical modules.

Abstract: Embodiments relate to lateral chromatic aberration (LCA) recovery of raw image data generated by image sensors. A chromatic aberration recovery circuit performs chromatic aberration recovery on the raw image data to correct the resulting LCA in the full color images using pre-calculated offset values of a subset of colors of pixels.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap the optical sensor. The display may include a black masking layer with a plurality of horizontal portions and a plurality of vertical portions that form a grid that defines a plurality of apertures. The black masking layer may additionally include patches in the apertures. The patches may be optimally positioned to mitigate diffraction artifacts in the sensor that operates through the pixel removal region. The patches may have unique sizes and shapes. The display may include first and second pixel removal regions with different black masking layer layouts. The layouts may cause complementary diffraction artifacts such that a single artifact-free image may be constructed using the first and second optical sensors.

Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

Abstract: An electronic device may have a display mounted in a housing. The display may have a pixel array that produces images. A display cover layer may overlap the pixel array. The display cover layer may have a planar central area surrounded by a peripheral edge area with a curved cross-sectional profile. From an on-axis viewing angle, an image on the pixel array is fully viewable through the planar central area and the peripheral edge area. From an off-axis viewing angle, the image is partly viewable through the peripheral edge area and not through the central area. To avoid an undesired color cast in the partly viewable image seen through the peripheral edge area of the display cover layer, the display may be provided with color cast compensation structures such as a guest-host liquid crystal layer that exhibits an anisotropic colored light absorption characteristic, a diffuser layer, and/or other optical structures.

Abstract: Techniques to protect a subscriber identity, by encrypting a subscription permanent identifier (SUPI) to form one-time use subscription concealed identifiers (SUCIs) using a set of one-time ephemeral asymmetric keys, generated by a user equipment (UE), and network provided keys are disclosed. Encryption of the SUPI to form the SUCIs can mitigate snooping by rogue network entities, such as fake base stations. The UE is restricted from providing the unencrypted SUPI over an unauthenticated connection to a network entity. In some instances, the UE uses a trusted symmetric fallback encryption key KFB or trusted asymmetric fallback public key PKFB to verify messages from an unauthenticated network entity and/or to encrypt the SUPI to form a fallback SUCIFB for communication of messages with the unauthenticated network entity.

Abstract: Techniques are disclosed for facilitating disabling an alarm in response to particular types of activity-indicative data. More specifically, activity-indicative data (e.g., sensor data or input(s) can be detected prior to a preset alarm time. Upon determining, based on the activity-indicative data, that a wakefulness condition is satisfied (e.g., that the activity-indicative data corresponds to one or more predefined characteristics), a disablement query can be displayed that includes an option to disable the alarm. In response to detecting a selection of the option, the alarm can be disabled such that the alarm stimuli is not to be presented at the preset alarm time.

Abstract: An electronic device may include wireless circuitry. The wireless circuitry may include a quadratic phase generator for outputting a perfectly interpolated constant amplitude zero autocorrelation (CAZAC) sequence for a transmit path. The quadratic phase generator may include a numerically controlled oscillator, a switch controlled based on a value output from the numerically controlled oscillator, a first integrator stage, and a second integrator stage connected in series with the first integrator stage. The numerically controlled oscillator may receive as inputs a chirp count and a word length. The switch may be configured to switchably feed one of two input values that are a function of the chirp count and the word length to the first integrator stage. The quadratic phase generator may output full-bandwidth chirps or reduced-bandwidth chirps. Bandwidth reduction can be achieved by scaling the two input values of the switches.

Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.

The receiving device is configured to allow prioritized notification alerts for incoming call connection requests and/or for incoming messages from a sending device to override a silent or do not disturb mode for one or more contacts based on i) a priority level provided with the call connection request or message and ii) a priority setting for the sending device or a set of devices associated with a user of the sending device.

Abstract: Systems and methods of adjusting contention window size (CWS) in a LBT procedure for both UL and DL unlicensed spectrum transmissions are described. The UE makes a HARQ-ACK determination for at least one code block group (CBG) of a transport block (TB) in a reference burst from a base station, determines whether the HARQ-ACK determination for the CBG meets a predetermined number of NACKs, transmits to the base station a single bit HARQ-ACK feedback for the TB that is dependent on whether the predetermined number of NACKs has been met, and receives or determines the adjusted CWS and uses the adjusted CWS for communication with the base station.
