A system for controlling multiple energy storage devices in an uninterruptible power supply (UPS) system is provided. In one embodiment of the invention, the system generally includes a charger coupled to a direct current (DC) bus of the UPS system, and two or more energy storage circuits, each of which includes a power regulator coupled to the charger and coupled to the DC bus, at least one energy storage device coupled to the power regulator, and a processor coupled to the power regulator for controlling the charge and discharge of the at least one energy storage device. In another embodiment of the invention, digital communication between two or more controllers is accomplished over the DC bus through use of the Control Area Network (CAN) protocol.

According to one aspect of the invention, a UPS includes an input configured to be coupled to an AC power source, a DC power source, an output configured to receive power from at least one of the AC power source and the DC power source, a first switched receptacle outlet coupled to the output and configured to be coupled to a first electrical load and a second receptacle outlet coupled to the output and configured to be coupled to a second electrical load. According to some embodiments, the UPS also includes a control unit configurable to provide a first configuration associated with the first switched receptacle outlet, where the first configuration is employed by the control unit to control a connection of the first switched receptacle outlet to the output independent of the second receptacle outlet.

One aspect relates to a communication protocol for communicating between one or more entities, such as devices, hosts or any other system capable of communicating over a network. A protocol is provided that allows communication between entities without a priori knowledge of the communication protocol. In such a protocol, for example, information describing a data structure of the communication protocol is transferred between communicating entities. Further, an authentication protocol is provided for providing bidirectional authentication between communicating entities. In one specific example, the entities include a master device and a slave device coupled by a serial link. In another specific example, the communication protocol may be used for performing unbalanced transmission between communicating entities.

Systems and methods of re-enumerating peripheral devices operatively connected to a computer system are provided. In one example, a system is configured to disable an existing connection between an operating system and a peripheral device established through a device driver by re-describing the peripheral device to the OS. In another example, the system can be further configured to execute operation(s) on the peripheral device without new driver installation using communication channels native to the OS. Once the operation(s) are complete, the system can be configured to restore the existing connection.
