Abstract: The disclosure relates to technology for preventing a drop event for a mobile device. Sensor data is collected from the mobile device using one or more sensors to determine a pattern and/or current behavior of a user. A potential drop event risk of the mobile device is then determined based on the pattern and/or the current behavior of the user, and a notification is sent to the user of the mobile device indicating the potential drop risk when the pattern and/or the current behavior of the user is determined to satisfy a threshold risk level.

Abstract: Disclosed here are systems and methods which enable high-bandwidth communication between a mobile device and an accessory. The high-bandwidth communication uses electromagnetic waves in the extremely high frequency range between 30 GHz and 300 GHz inclusive, also known as millimeter waves. The millimeter waves travel through at least the chassis of the accessory and the chassis of the mobile device without significant scattering and attenuation. The properties of the materials through which the millimeter waves travel determine the attenuation of the millimeter waves. Disclosed here are various materials, and their thicknesses, which form a transmission stack through which the millimeter waves can travel unimpeded. In effect, the transmission stack acts as a dielectric member which facilitates the transmission of the millimeter waves, while attenuating transmission of waves outside of the extremely high frequency range.

The 360-degree camera accessory includes a camera module disposed partially within the camera accessory, where the camera module including an optical lens configured to capture an image of a scene. The 360-degree camera accessory also includes a rigid structure disposed within the accessory to support the camera module, and a deformable structure disposed between a camera barrel that surrounds the optical lens of the camera module and the rigid structure. The deformable structure can compensate for movement of the camera module to improve image capturing of the scene.

Abstract: An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. To facilitate bending about the bend axis, the display may have layers such as a display cover layer with grooves or other recesses. The recesses form a flexible portion in the display layer. The display layer may be formed from glass or other materials that are transparent. Elastomeric material, fluids, and other materials may be placed in the recesses in the display layer. The material in the display layer may have an index of refraction that is matched to the index of refraction of the display layer. A hinge may be formed between rigid planar layers that are separated by a gap. Flexible layers that lie flush with opposing surfaces of the rigid planar layers may be used to span the gap.

A display in the electronic device may have a touch sensor layer such as an array of capacitive touch sensor electrodes. The display may have display layers in a plastic chassis structure and a metal chassis structure. A display layer may have a conductive surface.

Segments of conductive tape may run along each of the four edges of a display and may overlap at display corners. Conductive foam structures may be used to short the segments to adjacent portions of the conductive housing walls.
