Abstract:
The disclosed embodiments provide a battery cell. The battery cell includes a set of layers forming a non-rectangular shape, wherein the set of layers comprises a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a first conductive tab coupled to the cathode and a second conductive tab coupled to the anode. The layers are enclosed in a flexible pouch, and the first and second conductive tabs are extended through seals in the pouch to provide terminals for the battery cell. Furthermore, the non-rectangular shape is created by removing material from one or more of the layers.
Abstract:
An electronic device may have circuitry mounted on a printed circuit board. The circuitry may include electronic components such as integrated circuits, sensors, and switches that are sensitive to bending-induced stress in the printed circuit board. An overmolded plastic stress concentrator may be overmolded over the printed circuit board and the circuitry on the printed circuit board. A flexible plastic body may be used to enclose the stress concentrator and printed circuit board. The plastic body, stress concentrator, and printed circuit board may be elongated along a longitudinal axis. The stress concentrator may have unbent regions in which the printed circuit board is prevented from flexing and enhanced flexibility regions. Sensitive circuitry may be located in the unbent regions to prevent the sensitive circuitry from being exposed to bending stress.

Abstract:
Clasp assemblies for bands (e.g., for watches) are disclosed. In some embodiments, a clasp assembly may include a plurality of pivotally interconnected links, where respective links are releasably coupled to one another, and spring assemblies disposed between respective links impart biasing forces between the respective links. In some embodiments, a clasp assembly may include a clasp body, a clasp cover, and a connecting arm pivotally coupled to the clasp body at a first end of the connecting arm, and pivotally coupled to the clasp cover at a second end of the connecting arm. The clasp assembly may include springs, magnets, elastomer members, and/or other mechanisms, components, or assemblies that impart a biasing force between the clasp body, the connecting arm, and/or the clasp cover.
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:
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.
