    摘要： A wrist-worn electronic device configured to transmit and receive wireless signals in two frequency bands comprises a bezel loop antenna, first and second signal processing elements, a diplexer, and a tuning element. The bezel loop antenna has a first impedance and is configured to wirelessly receive first and second electronic signals simultaneously. The first and second signal processing elements process the first electronic signal having a frequency in a first frequency band and the second electronic signal having a frequency in a second frequency band. The diplexer is configured to receive the first and second electronic signals and output the first electronic signal to the first signal processing element and the second electronic signal to the second signal processing element. The tuning element has a second impedance causing the bezel loop antenna to wirelessly receive electronic signals in the first frequency band and electronic signals in the second frequency band.

    摘要： Systems and methods of generating electrical power for a portable electronic device from a photovoltaic power system are described herein. In some embodiments, a photovoltaic module comprises an interior surface and an exterior surface. The interior photovoltaic cells may be disposed in photovoltaic stripes on the interior surface and exterior photovoltaic cells may be disposed on the exterior surface. Substantially opaque materials are employed to provide a photovoltaic-powered portable electric device with an improved appearance.

    摘要： Systems and methods for generating electrical current from at least one photovoltaic cell is described herein. The photovoltaic cell may be disposed over a display of an electronic device. The photovoltaic cell may comprise first and second conductive layers and a photovoltaic layer. The first conductive layer may be etched such that a width of the metal layer is less than a width of the photovoltaic layer providing visibility to the display disposed below. In some embodiments, a capacitive touch sensor is disposed between the metal layer and the absorber layer for providing interaction with a user.

    摘要： Systems and methods of generating electrical current from at least one photovoltaic cell are described herein. In some embodiments, a dual-cell arrangement of photovoltaic cells may be disposed on a face. Equal parts of a first photovoltaic cell and a second photovoltaic cell may be disposed on the face such that when a portion of the face is shaded, the first photovoltaic cell and the second photovoltaic cell receive substantially equal amounts of electromagnetic radiation. In some embodiments, the first photovoltaic cell and the second photovoltaic cell comprises a plurality of sub-cell connected in series and parallel to optimize the power output form the partially exposed cells.
