Abstract: A USB wall plate charger for charging an external electronic device is mountable to a common 120 volt AC wall outlet, and includes a power supply to convert the 120 volts AC to +5 volts DC, and a charging profile configuration circuit. A charging profile selection switch is provided for the user to select a desired charging profile that is compatible with the electronic device to be charged.

Abstract: A nightlight charger for charging an external electronic device is mountable to a common 120 volt AC wall outlet, and includes a power supply to convert the 120 volts AC to +5 volts DC, and a charging profile configuration circuit. A charging profile selection switch is provided for the user to select a desired charging profile that is compatible with the electronic device to be charged. The nightlight includes a housing having a side wall, a portion of which is translucent. A light emitting device within the housing emits light that passes though the translucent portion of the side wall.

Abstract: A current selectable USB charger includes a USB (universal serial bus) connector, a crossover switch, a pair of voltage dividers and a power supply. The power supply provides preferably a +5 volt DC voltage to the pair of voltage dividers. The pair of voltage dividers includes a first voltage divider and a second voltage divider, each being formed of a pair of series-connected resistors. The voltage on the junction of the series-connected resistors of the first voltage divider is selectively provided, through the crossover switch, to one of the D? pin and the D+ pin of the USB connector. The voltage on the junction of the series-connected resistors of the second voltage divider is selectively provided, through the crossover switch, to one of the D+ pin and the D? pin of the USB connector.

Abstract: A compressed digital music adapting apparatus for vehicles is described, which includes a cigarette-lighter power port and an FM modulator/transmitter. The FM modulator/transmitter modulates compressed digital music from a digital music player and then transmits the modulated music to an FM receiver by coupling the RF output of the FM modulator/transmitter directly to a power supply terminal of the FM modulator/transmitter thus causing a loop of RF current flow which generates a magnetic radiating field.
