International Classification:

H02J 7/00

US Classification:

320110, 320106, 320107, 320114

Abstract:

A control module is included in a battery charger that is adapted to charge a plurality of battery packs of different types or a power tool that is adapted to be powered by at least one of the battery packs. The control module includes a remote sensing module that communicates remotely with one of the battery packs. The control module also includes a battery pack connection module that determines that the one of the battery packs is in electrical communication with at least one of the battery charger and the power tool. The control module also includes a battery pack identification (ID) module that determines a first type of the battery pack based on remote sensing module signals. The control module also includes a charge control module that determines at least one of a charge setting and a discharge setting for the battery pack based on the first type.

International Classification:

B41F 2706
B41F 2712

US Classification:

101382MV

Abstract:

Apparatus for mounting a flexible printing plate comprises a printing cylinder having a surface upon which the printing plate is mountable, and a connection for applying subatmospheric pressure inside the cylinder. A plurality of valves selectively apply the subatmospheric pressure to the surface from inside the cylinder. These valves have depressable actuating members protrudable above the cylinder surface. Those actuating members contacted by the printing plate when applied to the cylinder surface are depressed thereby to effect application of subatmospheric pressure to beneath the printing plate to draw the plate against the cylinder. Preferably, grooves are provided in the cylinder surface for distribution of the subatmospheric pressure beneath the plate. Advantageously, the printing plate may have a thin, highly flexible and deformable fringe along its trailing edge to seal the surface grooves, at that location. This mounting arrangement facilitates quick changing of printing plates during printing operations.
