Abstract: A power distribution circuit of an uninterruptible power supply is provided, where a first port of the power distribution circuit of the uninterruptible power supply is electrically connected to a second port. A third port is electrically connected to the second port by using a compensation circuit. When an input voltage of the first port is less than a rated voltage of a load of the second port, an input voltage of the third port is input to the compensation circuit. The compensation circuit converts a direct current into an alternating current, so that the alternating current output by the compensation circuit and the input voltage of the first port jointly supply power to the load of the second port.

Abstract: A controller, e.g., a software-defined network (SDN) controller, stores data representing a topology of a network that includes a plurality of network elements. A move is detected of a host between network elements in the network and a destination network element to which the host has moved is determined. The destination network element is designated as a root of a tree in the network. A topology for the tree is generated using the destination network element as the root of the tree. Following the topology of the tree, starting with the root, parent network elements in the tree are updated for a traffic flow for the host before child network elements are updated.

Abstract: A method and apparatus for generating a pronunciation score by receiving a user phrase intended to conform to a reference phrase and processing the user phrase in accordance with at least one of an articulation-scoring engine, a duration scoring engine and an intonation-scoring engine to derive thereby the pronunciation score. The scores provided by the various scoring engines are adapted to provide a visual and/or numerical feedback that provides information pertaining to correctness or incorrectness in one or more speech-features such as intonation, articulation, voicing, phoneme error and relative word duration. Such useful interactive feedback will allow a user to quickly identify the problem area and take remedial action in reciting “tutor” sentences or phrases.
