Patent number: 10985695Abstract: An arc detection method includes classifying whether an arc fault is present in the power system by, for each of a plurality of bins of a current frame of a signal, marking the bin as a candidate bin if a magnitude spectrum of the bin meets first criteria; determining a number of candidate bins in the current frame; marking the number of candidate bins as candidate cluster bins if the number of candidate bins exceeds a minimum cluster size; for each of the candidate cluster bins, determining whether the candidate cluster bin is also a candidate cluster bin of a previous frame of the first signal and if so, identifying the current frame as a candidate frame and incrementing a candidate frame count; and if the candidate frame count exceeds a candidate frame count threshold, determining that an arc fault is present in the power system.Type: GrantFiled: August 28, 2018Date of Patent: April 20, 2021Assignee: ANALOG DEVICES INTERNATIONAL UNLIMITED COMPANYInventors: Bijesh Poyil, Hans Brueggemann, Daniel Brian O'Malley

Clamps for repairing posts and methods and/or arrangements for repairing such posts with said clamps
Patent number: 9574365Abstract: A clamp arrangement includes a pair of brackets adapted to be clamped on opposing sides of the wooden post to encapsulate a fractured portion, each bracket is made from an integral sheet of metal cut and pressed to define a longitudinal hemispherical chamber and a pair of longitudinal flanges extended out from each, the longitudinal hemispherical chamber having an upper end wherein a lip is supported in the lateral extension by a multitude of pressed out ribs such that when the clamp arrangement is required to be driven into the ground about the wooden post, the lip provides a support location for an impact tool to drive the clamp arrangement into the ground.Type: GrantFiled: March 29, 2012Date of Patent: February 21, 2017Assignee: OCVITTI PTY LTDInventors: Nigel Catt, Brian O'Malley -
Patent number: 9359785Abstract: A metal post reinforcement arrangement adapted to be clamped about a broken section of a metal post, including two opposing brackets wherein when a bolt fixes one bracket to the other about the metal post the bolt divides the broken section into upper and lower portions so as to provide support and/or structural integrity when the reinforcement arrangement is clamped about the broken section and wherein each bracket has a substantially semi circular cross-sectional configuration along said bracket length that includes a longitudinal central segment terminating on opposed sides with internally directed curved edges with corresponding upwardly extended rounded shoulders that provide substantially triangular dimples on the internal side of the bracket, and wherein a peripheral flange stems out from a rounded dip from each substantially triangular dimple such that said brackets are adapted to be fixed around metal posts having different shapes.Type: GrantFiled: September 11, 2012Date of Patent: June 7, 2016Assignee: Ocvitti Pty LtdInventors: Nigel M Catt, Brian O'Malley

Publication number: 20070021002Abstract: A high speed connector includes a plurality of wafer-style components in which two columns of conductive terminals are supported in an insulative support body, the body including an internal cavity disposed between the two columns of conductive terminals. The terminals are arranged in horizontal pairs, and the internal cavity defines an air channel between each horizontal pair of terminals arranged in the two columns of terminals. The terminals are further aligned with each other in each row so that horizontal faces of the terminals in the two rows face each other to thereby promote broadside coupling between horizontal pairs of terminals.Type: ApplicationFiled: March 31, 2006Publication date: January 25, 2007Inventors: John Laurx, Craig Bixler, Kent Regnier, David Dunham, Brian O'Malley

Patent number: 6843687Abstract: A high-density connector utilizes a plurality of terminal assemblies that are assembled together into a block, or single unit, to form a connector. Each terminal assembly of the connector utilizes a plurality of conductive terminals having contact portions for mating with an opposing connector, tail portions for mounting to a circuit substrate and body portions held within an insulative body portion of the assembly. The body portions are supported within a housing in the form of a wafer which is plated with a conductive material so as to provide an all encompassing ground structure that surrounds the terminals and their insulative supporting terminal assemblies. In this manner a reference ground is provided around each signal terminal between its contact and tail portions that emulates a coaxial cable.Type: GrantFiled: February 27, 2004Date of Patent: January 18, 2005Assignee: Molex IncorporatedInventors: Daniel B. McGowan, Brian O'Malley, Kent E. Regnier
