Abstract: An electronic device structure having a shielding structure includes a substrate with an electronic component electrically connected to the substrate. The shielding structure includes conductive spaced-apart pillar structures that have proximate ends connected to the substrate and distal ends spaced apart from the substrate, and that are laterally spaced apart from the first electronic component. In one embodiment, the conductive pillar structures are conductive wires attached at one end to the substrate with an opposing end extending away from the substrate so that the conductive wires are provided generally perpendicular to the substrate. A package body encapsulates the electronic component and the conductive spaced-apart pillar structures. In one embodiment, the shielding structure further includes a shielding layer disposed adjacent to the package body, which is electrically connected to the conductive spaced-apart pillar structures.

Abstract: A vehicle battery charging device includes a controller configured to generate one of a first activation signal and a second activation signal, based on a start-up signal and a battery state information, a continuous charger configured to output first electric energy of a constant voltage level, based on the first activation signal, a pulse charger configured to alternately output a charging voltage and a discharge voltage as second electric energy depending on a preset ratio, based on the second activation signal, a battery configured to continuously charge by receiving the first electric energy or to pulse-charge by receiving the second electric energy, and a battery state detector configured to detect a state of the battery and to output the detected state of the battery as the battery state information.
