Abstract: Embodiments described herein include a sensor control device configured for secure over-the-air (OTA) programming. Embodiments include a sensor control device that includes one or more processors, an analyte sensor, a communication module, and a memory. The memory includes a first set of storage blocks that are in a non-programmable state and a second set of blocks that are in a programmable state. The processors are configured to receive, using the communication module, instructions to write marking data to the memory to mark a first storage block from the first set of storage blocks as inaccessible and to write program data to a second storage block from the second set of storage blocks, causing the second storage block to be placed into the non-programmable state. The program data written to the second storage block includes instructions that cause the processors to process analyte data received from the analyte sensor.

Abstract: Various implementations disclosed herein include electronic devices, systems, and methods that determine a characteristic of an eye based on detecting reflections of light. An example electronic device may include a scanning light source capable, a set of one or more photodiodes, a refractive/diffractive medium, and a processor. The refractive/diffractive medium includes a near-eye side and a far-eye side, and when the electronic device is worn, the near-eye side is proximate an eye of the user and the far-eye side is an opposite side of the refractive/diffractive medium such that light projected by the scanning light source that is reflected by the eye passes through the refractive/diffractive medium before capture by the set of one or more photodiodes. The processor may be configured to receive sensor data from the set of one or more photodiodes and determine a characteristic of the eye based on the sensor data.

Abstract: A gripping attachment (10) is disclosed which facilitates the handling of a medication bottle (12). The medication bottle includes a container (14) having a cylindrical wall (16) extending parallel to a longitudinal axis. The container is closed at one end by a base wall (18) and has an opposed open end. The container receives a cap (20) on the open end to enclose the container. The gripping attachment comprises a sleeve portion (22) having a sleeve wall (24) defining an internal, cylindrical surface configured to removably attach to the container wall. The gripping attachment further comprises a leverage component connected to the sleeve portion to facilitate gripping the sleeve portion.

Abstract: An electronic device may have a camera and a display. The display may be configured to display virtual reality content for a user in which no real-world content from the camera is displayed or mixed reality content in which a combination of real-world content from the camera and overlaid virtual reality content is displayed. Control circuitry in the device may adjust the display and camera while transitioning between virtual reality and mixed reality modes. The control circuitry may reconfigure the camera to exhibit a desired frame rate immediately upon transitioning from virtual reality mode to mixed reality mode. Transitions between modes may be accompanied by smooth transitions between frame rates to avoid visible artifacts on the display. The camera frame rate may be synchronized to the display frame rate for at least part of the transition between the virtual reality and mixed reality modes.

Abstract: Fiducial patterns that produce 2D Barker code-like diffraction patterns at a camera sensor are etched or otherwise provided on a cover glass in front of a camera. 2D Barker code kernels, when cross-correlated with the diffraction patterns captured in images by the camera, provide sharp cross-correlation peaks. Misalignment of the cover glass with respect to the camera can be derived by detecting shifts in the location of the detected peaks with respect to calibrated locations. Devices that include multiple cameras behind a cover glass with one or more fiducials on the cover glass in front of each camera are also described. The diffraction patterns caused by the fiducials at the various cameras may be analyzed to detect movement or distortion of the cover glass in multiple degrees of freedom.

Abstract: Fiducial patterns that include sub-patterns of dot-like markers are generated or applied on or in transparent glass or plastic material, for example an optical element such as a cover glass or lens attachment. A camera may capture multiple images through the glass or plastic element that include diffraction patterns caused by the fiducial patterns. The diffraction patterns from multiple images may be processed and analyzed to extract information including but not limited to centroids of the sub-patterns of the fiducial patterns. This information may, for example, be used to estimate location of the fiducial 10 patterns with respect to the camera, and thus to estimate pose of the glass or lens element with respect to the camera. Information such as serial numbers and prescriptions can also be encoded in the fiducial patterns and extracted from the respective diffraction patterns.

Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.
