  • Patent number: 10370748
    Abstract: An austenitic stainless steel having low nickel and molybdenum and exhibiting comparable corrosion resistance and formability properties to higher nickel and molybdenum alloys comprises, in weight %, up to 0.20 C, 2.0-9.0 Mn, up to 2.0 Si, 16.0-23.0 Cr, 1.0-5.0 Ni, up to 3.0 Mo, up to 3.0 Cu, 0.1-0.35 N, up to 4.0 W, up to 0.01 B, up to 1.0 Co, iron and impurities, the steel having a ferrite number of less than 10 and a MD30 value of less than 20° C.

  • Patent number: 10372585
    Abstract: A system and method that automatically detects that a regression incident has occurred, and identifies the particular revision(s) of source code that introduced the regression incident is disclosed herein. The system and method execute one or more simulations of each revision in a window of revisions of the source code to compute values for one or more metrics. The metric values are then used to compute regression confidence values as well as a regression confidence interval—to then detect a regression incident and identify the revision that caused the regression incident. The system and method can also identify subsequent revision(s) that sufficiently fix regression incident(s) caused by a revision such that a software developer can be informed of these fixing revisions.

  • Patent number: 10323308
    Abstract: An austenitic stainless steel composition having low nickel and molybdenum and exhibiting high corrosion resistance and good formability. The austenitic stainless steel includes, in weight %, up to 0.20 C, 2.0-6.0 Mn, up to 2.0 Si, 16.0-23.0 Cr, 5.0-7.0 Ni, up to 3.0 Mo, up to 3.0 Cu, 0.1-0.35 N, up to 4.0 W, up to 0.01 B, up to 1.0 Co, iron and impurities. The austenitic stainless steel has a ferrite number less than 11 and an MD30 value less than ?10° C.

  • Patent number: 6778099
    Abstract: A communications module that permits remote meter reading of a utility meter via a wireless modem that communicates using data packet networks along a communications system, such as ARDIS. The communications module is a microprocessor-based transmitter/receiver which receives data collection requests from a system server, initiates data collection from a utility meter, and reports the data back to a host computer system residing, for example, at a central office. Preferably, session-based communication using the meter protocol is implemented between the communications module and the meter, and packet switching is used between the communications server and the communications module through the network.
