H02J 7/00

US Classification:

320160, 320103, 320114, 320115

Abstract:

Multi-mode charger device for charging portable devices and methods of charging portable devices are described. In an embodiment, a multi-mode charger device has mode blocks respectively associated with modes of operation which are coupled to a switch module. The switch module is for coupling a selected one of the mode blocks to a peripheral bus and to decouple the mode blocks remaining from the peripheral bus. A first mode of the modes of operation is a pass through mode. A second mode of the modes of operation is a first charging mode. A third mode of the modes of operation is a second charging mode. The first charging mode and the second charging mode are different from one another.

International Classification:

H05K 700

US Classification:

361744

Abstract:

An electronic system having a plurality of electronic devices contained in a plurality of stackable enclosures is provided. Each of the plurality of stackable enclosures is stackable and interlockable together with another one of the plurality of stackable enclosures. Each of the plurality of stackable enclosures comprises a housing having a top surface and a bottom surface. A first plurality of projections are provided to extend upwardly from the top surface. The first plurality of projections are spaced to define a first group of grooves therebetween. A second plurality of projections are provided to extend downwardly from the bottom surface. The second plurality of projections are spaced to define a second group of grooves therebetween. Each of the second group of grooves corresponds to a respective one of the first plurality of projections. Each of the first group of grooves corresponds to a respective one of the second plurality of projections.
