    摘要： A circuit breaker detects a loose electrical connection condition of a power circuit. The circuit breaker includes first and second lugs, first and second acoustic couplers acoustically coupled to the power circuit, separable contacts electrically connected in series between the first and second lugs, and an operating mechanism adapted to open and close the contacts. An acoustic generator is coupled to the second acoustic coupler and generates a first acoustic signal to the power circuit from the second acoustic coupler. An acoustic sensor is coupled to the first acoustic coupler and has a second acoustic signal which is operatively associated with the loose electrical connection condition. The acoustic sensor outputs a sensed acoustic signal. A circuit cooperates with the acoustic generator to generate the first acoustic signal, input the sensed acoustic signal, and detect the loose electrical connection condition therefrom.

    摘要： A system and method for preventing contact weld under various fault current conditions is disclosed. The system includes a contactor having stationary and movable contacts biased towards each other and switchable between an open and closed position. Energization of an electromagnetic coil engages the contacts creating an electric path for current flow through the contactor. Pulse width modulation is used to lower the power to the coil and maintain the contacts in the closed position. The contactor is equipped with safeguards to prevent contact welding. Under low fault currents, welding is prevented by contact material composition. Under intermediate fault currents, the contacts are blown open and remain open using magnetic components until the arc dissipates and the contacts have cooled sufficiently. Under high fault currents, the arrangement causes the contacts to blow open and separate the armature from the coil preventing re-engagement of the contacts until the coil is energized again.

    摘要： A text content summary is created from speech content. A focus more signal is issued by a user while receiving the speech content. The focus more signal is associated with a time window, and the time window is associated with a part of the speech content. It is determined whether to use the part of the speech content associated with the time window to generate a text content summary based on a number of the focus more signals that are associated with the time window. The user may express relative significance to different portions of speech content, so as to generate a personal text content summary.
