Patent number: 11391759Abstract: A shunt is composed of multiple pieces with at least some of the pieces being connected by a conductive channel that provides uniform flow of current. The conductive channel may be a recess, raised portion, stand-alone component, or other channel that directs current to flow from one piece of the shunt to another piece in a uniform manner, resulting in an accurate current reading for the shunt. Further, the shunt may include multiple pieces that are composed of different materials.Type: GrantFiled: September 28, 2020Date of Patent: July 19, 2022Assignee: Itron, Inc.Inventor: David Nelson Makinson

Patent number: 10401392Abstract: A thermocouple device includes a shared conductor for a shunt measurement and a thermocouple measurement. For example, the thermocouple device may include a shared conductor that provides a signal to both calculate current of a shunt and calculate a temperature of the shunt. The thermocouple device may provide an efficient structure that accurately calculates current and temperature. In addition, the thermocouple device may use the temperature of the shunt to detect when a conductive path is overheating. The temperature of the shunt may also be used for other purposes.Type: GrantFiled: December 21, 2016Date of Patent: September 3, 2019Assignee: Itron, Inc.Inventors: David Nelson Makinson, Steven Grey

Patent number: 9910071Abstract: Disclosed is a metrology assembly that utilizes a multi-Hall effect device configuration which eliminates the necessity of a magnetic concentrator. In some embodiments, the metrology assembly includes a substrate or support platform configured to support at least two Hall effect devices per phase of an electricity meter. The metrology assembly may further include one or more electrical conductors coupled to the substrate and configured to conduct electric current. The at least two Hall effect devices may be coupled to the substrate at opposing sides of an associated electrical conductor, each Hall effect device being configured to detect a magnetic field created by the electric current of the associated electrical conductor, and to generate an output.Type: GrantFiled: January 7, 2016Date of Patent: March 6, 2018Assignee: Itron, Inc.Inventors: Vincent Mosser, Youcef Haddab, David Nelson Makinson, Steven Grey

Patent number: 9885743Abstract: Techniques for construction of an electric meter base level printed circuit board (PCB), such as for use in an electric consumption meter, are described herein. A plurality of heavy copper traces may be embedded in the PCB, thereby eliminating the need for heavy copper bar between connectors and components on the board. In one example, a PCB includes connectors for incoming and outgoing line and neutral conductors. The PCB may include a current measuring component, mounted on the PCB, to communicate with metrology circuitry. The PCB may include one or more switches, configured to regulate electrical service. Heavy electrical traces may be embedded in the PCB to connect the connectors and various components mounted on the PCB. The heavy electrical traces are sized to allow passage of currents that may be in excess of 100 amps.Type: GrantFiled: December 17, 2012Date of Patent: February 6, 2018Assignee: Itron, Inc.Inventors: David Nelson Makinson, Joseph Pontin
