    摘要： A portable DVD player includes a generally thin prismatic enclosure having a first major surface, a second major surface separated from the first major surface, and side surfaces connecting the first major surface to the second major surface. At least a portion of the first major surface includes a video display. The enclosure further includes a DVD entry port such that a DVD can be inserted into the enclosure. A digital processing system within the enclosure includes a decoder, a deinterlacer, and a display controller. The decoder receives signals from a DVD inserted into the enclosure to provide a decoded, interlaced video signal, the deinterlacer converts the interlaced video signal to a deinterlaced video signal, and the display controller uses the deinterlaced video signal to provide progressively scanned video on the video display. Preferably, the portable DVD player is both mechanically and electronically isolated for physical shocks to the player.

    摘要： In some implementations, an electronic device includes an actuator having a coil and a magnet, at least one of which may be movable relative to the other. The coil may receive a drive current to cause movement of at least one of the magnet or the coil, such as to provide a haptic output, motivate a loudspeaker, or the like. A transceiver electrically coupled with the coil through a connection circuit may use the coil as an antenna for at least one of sending or receiving a radio frequency communication through the coil. Additionally, or alternatively, the coil may be placed into proximity to a source of a magnetic field to induce an electric current in the coil. The induced electric current may be passed from the coil to a power management system, such as to charge a battery or the like.

    摘要： User interface experiences with electronic devices are enhanced with feedback cues such as haptic or vibrotactile output feedback. One or more piezoelectric actuators generate haptic output. The one or more piezoelectric actuators may be integrated onto a display substrate, a battery case, a device enclosure, or other component. Such integration may improve propagation of the haptic output to the user, reduce bulk of the electronic device, minimize parts count, and reduce production costs.

    摘要： The present invention is a printed circuit board having conductive layers split into electrically isolated voltage supply plane regions each plane region being connectable to an external supply voltage. The voltage supply plane regions are split to reduce the total number of PCB conductive layers. Voltage supply plane regions are configured to match the device voltage requirements and their placement on the PCB. In the case in which a circuit includes a device having two voltage supply requirements, a first set of the device's power supply pins are fixedly coupled to a first voltage supply plane region and a second set of the device's power supply pins are fixedly coupled to a second voltage supply plane region. In this instance, each of the first and second voltage supply plane regions are fixedly connectable to external voltage supplies or to a voltage regulator according to the voltage supply requirements of the device.

    摘要： A wide dynamic range charger module is configured to couple a variable power source such as a photovoltaic cell to a load. The module determines a maximum power point (MPPT) of the power source and based at least in part upon that MPPT selects one of a plurality of power converters to provide power to the load. The selection is such that the selected power converter is operating within its operating regime. The selected power converter may further be configured to a pre-determined input admittance which corresponds to the power source.
