Appl. No.:

09/711752

Inventors:

Aaron Fitzgerald - Faribault MN
Gary Larson - Waseca MN

Assignee:

Itron, Inc. - Waseca MN

International Classification:

G08B 2300

US Classification:

34087002, 32420713, 324609, 73 116

Abstract:

A low impedance encoder generally comprises a clock source and a switch. The clock source operates according to a predetermined duty cycle. The switch has a first position, closed, and a second position, opened. The duty cycle controls a current flow the switch. A high current flow through the switch indicates that the switch is closed and that the consumption of a utility as registered by the utility meter has occurred; the switch will continue to open and close throughout the process of metering. A low current flow through the switch indicates that the switch is open.

Abstract:

A method for printing a three-dimensional part with an additive manufacturing system, the method including printing layers of the three-dimensional part and of a support structure for the three-dimensional part from multiple print heads or deposition lines, and switching the print heads or deposition line between stand-by modes and operating modes in-between the printing of the layers of the three-dimensional part and the support structure. The method also includes performing a purge operation for each print head or deposition line switched to the operating mode, where the purge operation includes printing a layer of at least one purge tower from the print head or deposition line switched to the operating mode.
