Abstract:
A battery assembly for use in an electronic device is provided. The battery assembly may include a battery cell (e.g., a rechargeable battery cell), a battery connector for providing power from the battery cell to the electronic device, and a flex circuit electrically coupling the battery cell to the electronic device. The battery connector may be located adjacent the battery cell, and may include one or more alignment mechanisms for ensuring that conductive pads of the battery connector align properly with corresponding conductive elements of the electronic device. The battery cell may be fixed to the electronic device using an adhesive layer (e.g., double sided tape) placed between the cell and the electronic device. A tab may extend beyond the periphery of the battery cell to allow a user to pull or peal the battery cell from the electronic device for replacement or repair. In some embodiments, a tool may be used to grasp the tab.
Abstract:
A handheld electronic device may be provided that contains a conductive housing and other conductive elements. The conductive elements may form an antenna ground plane. One or more antennas for the handheld electronic device may be formed from the ground plane and one or more associated antenna resonating elements. Transceiver circuitry may be connected to the resonating elements by transmission lines such as coaxial cables. Ferrules may be crimped to the coaxial cables. A bracket with extending members may be crimped over the ferrules to ground the coaxial cables to the housing and other conductive elements in the ground plane. The ground plane may contain an antenna slot. A dock connector and flex circuit may overlap the slot in a way that does not affect the resonant frequency of the slot. Electrical components may be isolated from the antenna using isolation elements such as inductors and resistors.

Abstract:
Laminate lanyards and methods for making the same are disclosed. The laminate lanyards may include a head formed from a reinforcing loop of yarn incorporated within a scrim. The head can be coupled to the head section of a body, which also includes a main section that forms the loop of the laminate lanyard. A gusset can be coupled to ends of the main section of the body to couple the two ends of the body together and facilitate opening and closing of the loop of the laminate lanyard. A slider may also be included in laminate lanyard for adjusting the size of the loop.
Abstract:
Electronic devices are provided with ejectable component assemblies. The ejectable component assembly may include a tray that can be loaded with one or more removable modules, wafers coupled to circuit boards, cages and retaining plates to assist in retaining the tray within the assembly. The ejectable component assembly may include springs operative to engage detents in the tray to retain the tray in the assembly. The ejectable component assembly may include a tray ejector mechanism for ejecting the tray from the assembly.
Abstract:
Electronic devices may have sensitive circuitry. To determine whether an electronic device has been exposed to excessive amounts of moisture, the electronic device may be provided with a moisture indicator. The moisture indicator may have a wicking layer of white paper and a red dye layer. If a portion of the moisture indicator is exposed to moisture, red dye may bleed into the white paper. The moisture indicator may be mounted in an input-output port opening or other portion of the electronic device where the state of the moisture indicator is visible. The moisture indicator may have sealed edges to reduce sensitivity to small amounts of moisture intrusion. Different regions of the moisture indicator may be provided with different sensitivities by forming structures that have altered moisture flow properties, by altering wicking layer thicknesses, or by otherwise spatially modifying moisture sensitivity.
Abstract:
The disclosed embodiments relate to the manufacture of a battery cell. The battery cell includes a set of layers including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a pouch enclosing the layers, wherein the pouch is flexible. The layers may be wound to create a jelly roll prior to sealing the layers in the flexible pouch. A curve may also be formed in the battery cell by applying a pressure of at least 0.13 kilogram-force (kgf) per square millimeter to the layers using a set of curved plates applying a temperature of about 85° C. to the layers.
Abstract:
A voice-controlled electronic device that includes a device housing having a longitudinal axis bisecting opposing top and bottom surfaces and a side surface extending between the top and bottom surfaces. The device can further include one or more microphones disposed within the device housing and distributed radially around the longitudinal axis; a processor configured to execute computer instructions stored in a computer-readable memory for interacting with a user and processing voice commands received by the one or more microphones and first transducer and second transducers configured to generate sound waves within different frequency ranges.
Abstract:
Portable electronic devices are provided. Each device may be formed from two parts. A first part may be provided with components such as a display, a touch screen, a cover glass, and a frame. A second part may be provided with a plastic housing, circuit boards containing electrical components, and a bezel. Engagement members may be connected to the first and second parts. The engagement members may be formed from metal clips with holes and springs with flexible spring prongs that mate with the holes in the clips. The metal clips may be welded to frame struts on the frame and the springs may be welded to the bezel. During assembly, the first part may be rotated into place within the second part. Retention clips attached to the frame may be used to secure the two parts together. Assembly instructions and associated connector numbers may be provided within the devices.
