20090267559 | Mobile electronic equipment and battery charger cradle - Mobile electronic equipment incorporating an induction coil and a battery; and a battery charger cradle for recharging the battery in the mobile electronic equipment. Regarding the charger cradle, a bottom surface of a mounting portion is curved in a U-grooved shape, and a primary coil is incorporated inside the U-grooved bottom surface, with the primary coil being connected to a power source. Regarding the mobile equipment, its rear surface placed on the mounting portion of the charger cradle is curved to match with the U-grooved bottom surface, and the induction coil is incorporated inside the curved rear surface. When the mobile equipment is placed on the mounting portion of the charger cradle, the electric power is carried from the primary coil to the induction coil which are electromagnetically coupled with each other, and the battery in the mobile equipment is recharged by the electric power induced to the induction coil. | 10-29-2009 |
20090267560 | Battery pack - The battery pack instead of the size AA battery is loaded in a battery storage of an electronic device. The battery pack includes a battery casing, a plurality of size AAA batteries, a battery holder, a circuit board, and an induction coil electromagnetically connected to a primary coil of a battery charger cradle. The size AAA batteries are accommodated in the battery casing in a spaced-apart manner where a distance between longitudinal axes of the size AAA batteries is larger than a distance between longitudinal axes of the size AA batteries loaded in the battery storage, and a storage space is defined between the adjacent size AAA batteries. With an electronic component, mounted on the circuit board, being disposed in the storage space, the battery pack accommodates the size AAA batteries, the battery holder, the circuit board, and the induction coil in a mutually layered state in the battery casing. | 10-29-2009 |
20090278505 | BATTERY-CONTAINING UNIT AND CHARGING BASE - A battery-containing unit and a charging base are a battery-containing unit includes a lithium ion battery, and a charging base to which the battery-containing unit to be charged is placed. The battery-containing unit includes a charging circuit that converts an alternating current produced in an energized coil into a direct current, and a transmitter that detects the voltage of the lithium ion battery and transmits a voltage signal to the charging base. The charging base includes a receiver that receives the signal from the transmitter and detects the voltage signal, and a high frequency power supply that provides AC power to the energizing coil The power supply of the charging base detects the voltage of the lithium ion battery through the receiver and the transmitter, and is controlled to charge the lithium ion battery so that the voltage of lithium ion battery does not exceed a predetermined voltage. | 11-12-2009 |
