Abstract: A battery charger is configured to independently charge a plurality of single cells in a battery of series connected single cells. In one example, the battery charger provides a plurality of independent charging current paths to the plurality of single cells via a plurality of removable charging connectors. Each charging connector is associated with a different charging stage and configured to connect to a single cell of a battery of single cells connected in series. A top charging stage and each of a plurality of middle charging stages are grounded by independent isolated grounds. A bottom charging stage is grounded by a main ground. The respective, independent grounds of the charging stages serve as the reference voltages for charging each of the single cells independently.

Abstract: A building control system is provided that receives information from devices of different subsystems. A trigger causes a zone controller to store the information in a database. The stored data is used to generate customized reports based on sequences or sets of related events. The information from multiple subsystems is consolidated, analyzed, and patterns of behavior are determined. The trigger also causes execution of control actions throughout the building spanning the multiple subsystems, devices, and areas based on the information. An access control subsystem and a non-access control subsystem of the building control system are linked using a common network such that a change in the state of an access control device can affect the state of a non-access control device and a change in the state of a non-access control device can affect the state of an access control device.
