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 power supply unit for a mobile computerized device includes a housing having a handle, a battery positioned within the housing, and a detector configured to detect user interaction with the handle. The power supply unit may comprise a removable power supply unit for a mobile computerized device, having a detector generating a signal in response to detecting user interaction with the handle.

Abstract: A power system for a mobile workstation includes a docking station for a removable battery, a power bus, and a power interface having an output interface electrically connected with the power bus. The power system further includes a detector configured to detect user interaction with a removable battery docked with the docking station, and a switching device coupled with the detector and configured to switch the power interface from a first power sourcing mode to a second power sourcing mode receiving power from a back-up battery, in response to detecting user interaction with a removable battery docked with the docking station.

Abstract: A mobile workstation includes a frame having a wheeled base, a power system resident on the mobile workstation and a battery docking station having a holster which defines a guide. The mobile workstation further includes a removable battery assembly configured to dock with the battery docking station via engagement in the guide, and having a housing with a shape complementary to a shape of the guide and an external contour configured to mate with an internal contour of the guide.

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.
