Inventor: KO WON JUN
IPC: H02J7/00
Filed: 2003-04-09
Abstract: PURPOSE: An apparatus for charging a robot is provided to charge easily a battery of a robot without connecting electrically the robot to a main body of a charger. CONSTITUTION: A supply charging part(38) is installed at a main body(10) and is formed with an RF current generator for converting AC power to RF current, a primary induction coil(40) for generating electromagnetic field from the RF current, and a supply terminal for radiating the electromagnetic field. A charging part(54) is installed at a robot and is formed with a receiving terminal connected to the supply terminal, a secondary induction coil(56) for generating inductive current from the electromagnetic field of the primary induction coil, and a DC converter(42) for rectifying the inductive current and supplying DC power to a battery.

Abstract: PURPOSE: An apparatus of checking whether or not of live wire is provided to easily check whether a live wire or not by operating selectively according to a live wire state. CONSTITUTION: A conductor ring(10) is coupled to surround the outer circumference of a power cable. A conductor stick(11) is extended from one side of the conductor ring in a spaced direction from the power cable. A metal foil(12) is provided at an end part of the conductor stick and is pushed selectively by a repulsive power at electrostatic induction. A container part(13) receives the conductor stick and the metal foil in its inner space.
