20080203995 | Methods of discharge control for a battery pack of a cordless power tool system, a cordless power tool system and battery pack adapted to provide over-discharge protection and discharge control - In a cordless power tool system, a battery pack which may removably attachable to a cordless power tool and to a charger may include at least one battery cell and a power limiting device. The power limiting device may be arranged in series with the at least one battery cell for limiting power output of the battery pack based on the component that is connected to the pack. Current and hence power out of the battery pack may be controlled as a function of total internal impedance in the battery pack, which may be adjusted depending on the component that is connected to the pack. | 08-28-2008 |
20080238370 | BATTERY PACK FOR CORDLESS POWER TOOLS - A battery pack which includes a battery pack electronic control circuit adapted to control an attached power tool and/or an attached charger. The battery pack includes additional protection circuits, methodologies and devices to protect against fault conditions within the pack, as the pack is operatively attached to and providing power to the power tool, and/or as the pack is operatively attached to and being charged by the charger. | 10-02-2008 |
20090015410 | WIRELESS ASSET MONITORING AND SECURITY SYSTEM - An asset monitoring and security system includes at least one asset assigned a unique identifier and operable wirelessly transmit an identification signal embodying the identifier. A data store maintains a list of the assets and privileges associated with the assets for authorized users of the assets. A control unit is adapted to receive identification signals from the assets and monitor positions of the assets within a defined area. The control unit communicates with the data store and is further operable to initiate an alarm event when privileges associated with a given asset for authorized users of the asset are exceeded. Each of the assets includes a lock-out mechanism that impedes use of the asset when the lock-out mechanism is activated. The control unit activates the lock-out mechanism of a given asset when the privileges associated with the asset for authorized users of the asset are exceeded. | 01-15-2009 |
20100213900 | BATTERY PACK FOR CORDLESS POWER TOOLS - A battery pack which includes a battery pack electronic control circuit adapted to control an attached power tool and/or an attached charger. The battery pack includes additional protection circuits, methodologies and devices to protect against fault conditions within the pack, as the pack is operatively attached to and providing power to the power tool, and/or as they pack is operatively attached to and being charged by the charger. | 08-26-2010 |
20110095883 | ASSET MONITORING SYSTEM AND PORTABLE SECURITY SYSTEM THEREFOR - A portable security system for monitoring an asset has one or more alarm sensors and a wireless transmitter/receiver that communicates via wireless communication with a host system. The portable security system is switchable between a disabled (partially powered) state and an enabled (fully powered state) in response to commands received from the host system. In an aspect, the portable security system has a plurality of alarm sensors which a user can separately activate and deactivate via the host system. In an aspect, the portable security system includes a base unit and an auxiliary unit. The base unit includes one or more of the alarm sensors that serves a dual purpose depending on whether the base unit is mated with the auxiliary unit. In an aspect, the host system can be utilized by multiple users to manage portable security systems associated with the respective users, including management by group. In an aspect, the host system notifies a user(s) of an alarm condition(s). | 04-28-2011 |
