Abstract: A battery charging system includes a housing having a plurality of docking stations coupled therewith. A control device is coupled with a battery charging interface of each of the plurality of docking stations, and is configured to reduce variation in charging cycle count among a plurality of batteries configured to dock with the battery charging interfaces. A method of reducing variation in charging cycle count in a system of batteries includes receiving inputs associated with a charging cycle count for each of a plurality of interchangeable batteries docked with a common battery charger, and outputting a battery selection signal based at least in part on the inputs.

Abstract: A vertically adjustable mobile computer workstation includes a first arm which has an upper end and a lower end. Attached to the upper end of the first arm is at least one platform. A second arm includes an upper end and a lower end. The lower end of the first arm and the upper end of the second arm are hingedly attached. The lower end of the second arm is attached to a base that is supported by a plurality of rotatable members. The first arm is rotatable between a first angular position in which the at least one platform is positioned above the rotatable members and a second angular position in which the at least one platform is positioned higher above the rotatable members.
