Abstract: An electronic device comprises a housing, a motion sensor configured to sense motion of the housing, and a processor configured to determine an impact geometry based on the motion. A countermeasure system comprises an actuator coupled to an actuated member. The actuated member is operable by the actuator to modify the impact geometry, so that impact energy is redirected away from an impact sensitive component of the electronic device to an energy absorbing component of the electronic device.

Abstract: Electronic devices may include displays. A display may include backlight structures that generate light and display layers that generate images using the generated light. An electronic device may include an opaque flexible printed circuit that is wrapped around one or more edges of the backlight structures. The opaque flexible printed circuit may prevent light from the backlight structures from reaching other electronic components or escaping from the device. The opaque flexible printed circuit may include signal lines that communicate signals between a printed circuit board and the display. The opaque flexible printed circuit may be a layer of the printed circuit board that extends from an edge of the printed circuit board. The printed circuit board may include an additional flexible extended printed circuit layer that wraps around a surface of the printed circuit board and forms a portion of a conductive shield over that surface.

Abstract: An electronic device contains electrical circuits. The circuits may include circuitry on printed circuit boards and components such as a touch screen display and buttons. Signal paths for routing signals between the electrical circuits may be formed from metal traces on flexible printed circuit cables. The flexible printed circuit cables may be bent around one or more bend axes. A flexible printed circuit cable may be formed from a flexible polymer substrate having one or more layers of polymer. Upper and lower ground layers may be supported by the flexible polymer substrate. The metal traces for the signal paths may lie between the upper and lower ground layers. Longitudinal slits within the flexible printed circuit may be formed that pass through the ground layers and the polymer layers. Vias may be formed that couple the ground layers together. The vias may run along the edges of the slits.

Abstract: Pressure indicator pressure sensitive adhesive may contain microspheres that burst and release indicator when subjected to pressure and thereby produce a detectable indication of how much pressure has been applied when forming an adhesive joint between opposing structures. Electronic device structures can be assembled using the pressure indicator pressure sensitive adhesive. A camera or other sensor may monitor joint formation. The camera can gather infrared image data, visible light image data, or ultraviolet light image data. Sensor data such as magnetic or ultrasonic sensor data can also be collected on an adhesive joint. Joint inspection can be performed on test structures and production structures and corresponding adjustments made to the joint formation process. Positioners and other equipment that compresses the pressure indicator pressure sensitive adhesive can be adjusted in real time or calibrated using information about the condition of the pressure indicator pressure sensitive adhesive.

Abstract: An electronic device may have a conductive housing. A dielectric structure may be mounted in the conductive housing to form an antenna window. An electrical component such as a camera, light sensor, or other device may press against a conductive foam structure. A printed circuit may have conductive traces that form an antenna ground and antenna resonating element. The printed circuit may be wrapped around a support structure. The electrical component, the conductive foam structure, and the printed circuit wrapped around the support structure may be compressed between a display cover layer and the antenna window. A camera window may be attached to a camera window trim using multiple adhesives. The trim may have a curved exterior surface that matches a curved housing surface. A flexible printed circuit cable may have a folded portion. A band structure may surround the folded portion to form a service loop.

Abstract: Printed circuit substrates may be formed from rigid printed circuit material or flexible sheets of polymer. Printed circuit substrates may have conductive traces. Integrated circuits, touch sensor electrode structure, sensors, and other components may be mounted to the conductive traces. Connectors such as board-to-board connectors may be used to couple printed circuit substrates together. To hold the connectors together and to provide electromagnetic shielding, printed circuits and connectors may be surrounded by printed circuit connector securing structures. The printed circuit connector securing structures may have one or more strips of conductive fabric tape wrapped around the connectors. Metal stiffening members may be attached to opposing ends of the strip of conductive tape to facilitate removal of the tape for rework or repair. An additional strip of tape may be used to help secure the wrapped conductive tape. The additional strip may have a tab to facilitate removal.
