摘要： The present invention is directed to an electrical wiring device that includes at least one sensor that provides a sensor output signal corresponding to electrical perturbations propagating on the plurality of line terminals or the plurality of load terminals. A protective circuit assembly configured to detect a fault condition when the sensor output signal substantially corresponds to at least one predetermined fault criterion and generate a trip actuation signal in response thereto. A solenoid coil is configured to generate a trip actuation force in response to the trip actuation signal. A circuit interrupter assembly includes movable contacts configured to be driven into a tripped state in response to the trip actuation force. An automatic fault simulation circuit is configured to generate a self-test signal without execution of software code. The self-test signal is generated such that it is sensed by the at least one sensor if the at least one sensor is operational. An end-of-life detection circuit is coupled to the protective circuit assembly. The end-of-life detection circuit is configured to monitor the protective circuit assembly without execution of software code. The end-of-life detection circuit is configured to substantially inhibit the trip actuation force when the protective circuit assembly detects the fault condition and generates the trip actuation signal in response to the self-test signal. The end-of-life detection circuit is configured to generate an end-of-life response if the protective circuit assembly does not respond to the self-test signal within a predetermined period of time.

摘要： The present invention is directed to a protection device that includes line terminals coupled to a power source disposed in an electric power distribution system. The protection device is configured to protect a portion of the power distribution system from at least one fault condition. The device includes a receptacle member that includes a housing and a cover. The cover includes receptacle openings configured to accommodate plug contact blades. Receptacle contacts are disposed in the housing. The receptacle contacts are also coupled to the line terminals to thereby establish an electrical connection between the receptacle contacts and the line terminals. Each receptacle contact is in communication with a corresponding receptacle opening. A protective shutter mechanism is integrated into the housing. The protective shutter mechanism is movable from a closed position to an open position upon insertion of the plug contact blades. The protective shutter mechanism is substantially hermetically sealed in the closed position. The protective shutter mechanism is also not movable from the closed position to the open position upon insertion of an object into only one receptacle opening, such that the object is prevented from making contact with the corresponding receptacle contact.

摘要： A noise reduction system is connected to at least two input channels for receiving input signals that have substantially identical program content but differing instantaneous noise transients. The system selects a filtered input signal that has the lowest instantaneous noise transient level. In another aspect, the noise reduction system removes instantaneous transient noise from an input signal by way of a blanker. The blanker includes a switch that opens whenever a band-pass filtered input signal is greater than the average level of the signal by a predetermined proportional amount. The input signal also includes continuous noise that is removed by a continuous noise suppressor. The continuous noise is removed by a low pass filter whose corner frequency is responsive to a differentiated input signal divided by the program component signal, or vice versa. In another aspect, the noise reduction system includes at least two of a switcher, blanker or continuous noise suppressor in connected in series to remove both instantaneous noise transients and continuous noise from an input signal.
