Title: Protective circuit and protective plug for telecommunication installations
Inventor: HONL ROBERT
IPC: H01H15/08
Filed: 1991-08-08
Granted: 1998-09-22
Abstract: The invention relates to a protective circuit for the protection of a system to be protected from overvoltage and over-current, in particular for telecommunicationinstallations. The protective circuits comprise a fuse connected into the line conductor, and a surge arrester with a heat-sensitive protection device, forming a cross path between the line conductor and an earth conductor, the heat-sensitive protection device disconnecting the cross path in case of excessive power, and connecting the line conductor to the earth conductor. In the protective circuit of the present invention, the response of the heat-sensitive protection device will cause disconnection of the cross path of the surge arrester and closing of a short-circuit cross path provided on the system side of the fuse between the line conductor and the earth conductor. The protective circuit can be accommodated in a miniature plug for application in telecommunication installations.

Title: Ground fault interruptor circuit with electronic latch
Inventor: BAER MARK
IPC: H02H3/33
Filed: 1992-04-21
Granted: 2001-12-18
Abstract: A ground fault interruptor circuit interrupts the flow of current to a pair of lines extending between a source of power and a load. The ground fault interruptor circuit includes a circuit brewer comprising a normally open switch located in one ar both of the lines, a relay circuit for selectively closing the normally open switch, an electronic latch circuit operable in first and second bi-stable states and a fault sensing circuit for sensing the presence of a fault condition in at least one of the lines. The electronic latch circuit causes the relay circuit to close the normally open switch and maintain the normally open switch in its closed position when the electronic latch circuit is in the first bi-stable state. The electronic latch circuit also causes the relay circuit to permit the normally open switch to return to its normally open condition when the latch circuit is in its second bi-stable state. A fault sensing circuit senses the presence of a fault condition in at least one of the lines and causes the electronic latch circuit to latch in its second state upon detection of the fault condition.

Abstract: A method and system for locating field breaks within input data is provided. In a preferred embodiment, a software facility locates field breaks within input data. The facility first receives input data made of a large number of rows of text. The facility then selects a group of the received rows of text to analyze. The facility identifies field breaks within the input data by analyzing the selected group of rows of text. The facility preferably analyzes the selected rows by counting the number of substantive characters in each column of the selected rows. The facility then uses the count to determine which columns have less than a field-break threshold of substantive characters. The facility locates one field break within each series of columns that have less than the field-break threshold of substantive characters.
