Abstract:
An electronic device may contain electrical components mounted on one or more substrates such as printed circuit boards. During a drop event, the printed circuit boards and components may be subjected to stresses. Strain gauges may be formed from metal traces embedded within dielectric layers in the printed circuit boards. The strain gauges may be used to make stress measurements at various locations on the boards. Stress data may be collected in response to data from an accelerometer indicating that the device has been dropped. Stress data collection may be halted in response to determining that the device has struck an external surface. Impact may be detected using accelerometer data, strain gauge output, or other sensor data. Stress data may be analyzed by the electronic device or external equipment.
Abstract:
An electronic device contains circuitry such as radio-frequency transceiver circuitry and antenna structures that are coupled using transmission line paths such as coaxial cable paths. A coaxial cable is mounted within an electronic device housing cable mounting structures. The coaxial cable has a meandering portion that forms a service loop. The cable mounting structures includes grooves that receive the meandering portion of the cable. The grooves may be formed within a molded plastic body. Patterned metal may be formed on the surface of the molded plastic body using laser-based processing techniques. The cable in the meandering portion may have a segment in which an outer cable conductor is exposed. The patterned metal on the molded plastic body may short the exposed outer conductor to the electronic device housing or other ground structure.
Abstract:
The described embodiments relate generally to electronic devices and to three dimensional modules for increasing useable space on a circuit board associated therewith. In some embodiments, the modules can have a cuboid geometry, and can include a number of surfaces having embedded circuit traces configured to interconnect electronic components arranged on various surfaces of the module. One of the surfaces of module can include at least one communication interface configured to interconnect the circuit traces on the module to associated circuit paths on a circuit board to which the module is coupled. In some embodiments the module can be operative as a standoff between the circuit board and another component of the electronic device.
Abstract:
The described embodiments relate generally to improvements to injection molding equipment. More specifically, concepts for reducing sink and improving cosmetics of portions of injection molded parts in close proximity to gate areas of an injection mold are disclosed. A cold runner system is described in which molding material disposed in a mold cavity is separated from excess molding material in the runner system shortly after the mold is filled at a predetermined packing pressure.
Abstract:
Adjustable antenna structures may be used to compensate for manufacturing variations in electronic device antennas. An electronic device antenna may have an antenna feed and conductive structures such as portions of a peripheral conductive electronic device housing member and other conductive antenna structures. The adjustable antenna structures may have a movable dielectric support. Multiple conductive paths may be formed on the dielectric support. The movable dielectric support may be installed within an electronic device housing so that a selected one of the multiple conductive paths is coupled into use to convey antenna signals. Coupling the selected path into use adjusts the position of an antenna feed terminal for the antenna feed and compensates for manufacturing variations in the conductive antenna structures that could potentially lead to undesired variations in antenna performance.

Abstract:
An electronic device has a housing in which components are installed. The components contain audio components having audio ports and terminals. Elastomeric material is molded over the surface of an audio component so that the leads attached to the terminals protrude through the elastomeric material. The protruding portions of the leads are bent back to lie flush with the surface of the elastomeric material. The elastomeric material are configured to form elastomeric structures with an opening that is aligned with the audio port in a component. The housing of an electronic device has one or more openings that form an audio port. The opening in the elastomeric structures that are molded onto the audio component is aligned with the audio port in the housing and the audio port in the audio component. Mesh structures cover the audio port in the housing.
Abstract:
An electronic device may be provided with an electronic component such as a camera light source containing a light-emitting diode. During operation, the light-emitting diode may produce heat. Thermally conducting elastomeric structures may have features such as sidewalls that mate with external surface of the camera light source or other electronic component to dissipate heat from the electronic component. Metal structures such as a bracket may be used to press the elastomeric structures and the electronic component towards a wall of a housing for the electronic device. Support structures may be interposed between the wall of the housing and the elastomeric structures. The support structures may have an opening that is aligned with an opening in the housing wall. Insert structures may be received within the opening in the support structures. The electronic component may be aligned with the insert structures and the opening in the support structures.
Abstract:
One embodiment of a molded shield can include a cavity to conform to and receive an electrical component, a slit to conform to and receive a metal frame and a metal layer coupled to the top and lateral sides of the molded shield. In one embodiment, the molded shield can be formed from silicon and can include material to enhance electrical conductivity. The molded shield can couple to the metal frame which in turn can be coupled to ground with the resulting configuration acting to reduce electrical emissions. The molded shield can transfer heat away from the electrical component through conduction.
