Patent number: 9052351Abstract: A method and apparatus that monitors and controls an operation of an electricity meter. A potential failure condition of an electrical connection between an electricity meter and a meter socket in an electrical line that provides power from a power supply to an electrical load through the electricity meter, is detected. A correction time may be determined based on a temperature in a vicinity of and a current through the electrical connection, and may indicate an amount of time before a predicted failure of the electrical connection will occur. The method determines whether the electricity meter is in an imminent failure condition based on the correction time or the information used to detect the potential failure condition of the electrical connection. The method may provide either, or both, notification of the imminent failure condition and disconnection of power to the electrical load by operating a disconnection switch.Type: GrantFiled: September 19, 2012Date of Patent: June 9, 2015Assignee: SENSUS USA INC.Inventors: Marc L. Reed, Jared Rude, Andrew Dudding, Michael Brown, William R. Mazza, Jr.

Patent number: 8854217Abstract: A method and apparatus that monitors and controls the operation of an electricity meter, and modifies at least one temperature threshold for determining when an alarm message should be transmitted or an electrical connection in the meter should be disconnected. The method and apparatus includes a plurality of sensors that detect temperatures in various locations within the electricity meter. The method and apparatus compares at least one detected temperature to at least one threshold, and operates an alarm or a switch when the detected temperature exceeds the threshold. The method and apparatus determines an average rate of change for at least one temperature according to a short-term temperature average over a first number of samples of the temperature, and a long term-term temperature average over a second number of samples of the temperature. The second number of samples is different from the first number of samples.Type: GrantFiled: February 13, 2013Date of Patent: October 7, 2014Assignee: Sensus Spectrum LLCInventors: Michael R. Brown, William R. Mazza, Jr., Andrew James Bryce Dudding

Patent number: 8279027Abstract: A magnetic latching actuator operable to control the movement of at least a first contact and second contact between a closed position in which the contacts physically engage each other and an open position in which the contacts are spaced from each other. The magnetic latching actuator includes first and second stationary permanent magnets oriented such that the first magnetic field created by the first magnet and the second magnetic field created by the second magnet are in opposite directions. An actuation coil surrounds both the first and second magnets. Current is supplied to the actuation coil in a first direction to create a first magnetic field or a second direction to create a second actuation magnetic field opposite the first actuation magnetic field. A yoke is movable relative to the first and second magnets to cause the first and second contacts to move between the open and closed positions.Type: GrantFiled: May 8, 2009Date of Patent: October 2, 2012Assignee: Sensus Spectrum LLCInventors: Michael R.

Patent number: 7990239Abstract: At least one electrical contactor is provided that includes a fixed contact and a movable contact. The fixed contact includes a center leg and first and second arms that extend in opposite directions from the center leg. The movable contact associated with each fixed contact includes first and second blades positioned on opposite sides of the center leg. The first and second blades extend parallel to the center leg of the fixed contact such that when current flows through the electrical contactor, the current flow creates a force to push the first and second blades into the first and second arms of the fixed contact. The electrical contactor includes an actuating arrangement having a pair of cam members. The movement of the cam members causes pegs on each of the first and second blades to travel within the cam channel, thus opening and closing the contactor arrangement.Type: GrantFiled: May 8, 2009Date of Patent: August 2, 2011Assignee: M&FC Holding, LLCInventors: Michael R. Brown, William R. Mazza, Jr., Oliver Burstall, Alan Syrop

Patent number: 6453757Abstract: An ultrasonic gas meter housing member is configured to provide an associated multi-configuration ultrasonic gas meter assembly. The housing member is installable in an ultrasonic gas flow meter which includes an internal flow measurement tube along which gas travels for flow measurement, the tube having an inlet end and an outlet end. The ultrasonic gas meter housing member includes a closed back portion and a front portion spaced from the back portion to define a space for receiving the internal flow measurement tube such that the tube extends across the internal space of the housing member. At least one wall portion extends between the back portion and the front portion, the wall portion having a first opening and a second opening therethrough for connection of the housing member to a gas inlet pipe and a gas outlet pipe. The gas meter housing member is symmetrical about a plane which divides the housing member into a first portion and a second portion.Type: GrantFiled: May 6, 1999Date of Patent: September 24, 2002Assignee: M&FC Holding CompanyInventors: Dennis R.
