Publication number: 20240080678Abstract: A wireless industrial process filed device includes a process interface element configured to interface with a process fluid and control or sense a process variable of the process fluid. A controller is configured to control operation of the process interface element. An RF circuit board includes a plurality of RF transceivers carried on the RF circuit board, each configured to send and/or receive an RF signal which carries information related to the process variable. A plurality of antennas are carried on the RF circuit board and form an antenna array. Each of the plurality of antennas is coupled to at least one of the plurality of RF transceivers. Each of the plurality of antennas having a different antenna pattern. The controller controls operation of the plurality of RF transceivers to communicate with a remote device through an antenna array patterned formed by transmission of RF signals through the plurality of antenna patterns of the plurality of antennas.Type: ApplicationFiled: August 24, 2023Publication date: March 7, 2024Inventors: Laura Anne Schafer, Eric Darrell Rotvold, Jason Harold Rud, Theodore Henry Schnaare

Patent number: 8737244Abstract: A system for measuring and analyzing radio frequency power proximate and within a wireless field device mesh network. A centralized software module (CSWM) collects and analyzes values from one or more wireless devices of the wireless field device mesh network representing received RF power measurements on an assigned RF channel and values representing corresponding times of the received RF power measurements. Each wireless device measures received RF power on the assigned RF channel at times other than during reception of a signal resulting in transmission by the wireless device of either an acknowledgment signal or a non-acknowledgement signal. Values representing the received RF power measurements and the corresponding times of the received RF power measurements are determined from the stored received RF power measurements and corresponding times and then discarded. These values are stored within the wireless device until successfully reported.Type: GrantFiled: November 29, 2010Date of Patent: May 27, 2014Assignee: Rosemount Inc.Inventors: Eric Darrell Rotvold, Kelly Michael Orth, Daniel Clifford Carlson, Theodore Henry Schnaare, Joseph Citrano, III

Patent number: 7421531Abstract: A system couples fieldbus data from a fieldbus line to a network line. The system includes a data format converter that converts the data to USB data. A coupler that includes a first insulating barrier is coupled in cascade with the converter. A host receives the USB data. The host has a data server interface and a network connection. The data server interface presents the data to the network line. A regulator couples power between the host and the fieldbus line with the regulator including a second insulating barrier. Data and power are isolatingly coupled between the fieldbus line and the network line.Type: GrantFiled: January 12, 2005Date of Patent: September 2, 2008Assignee: Rosemount Inc.Inventors: Eric Darrell Rotvold, John P. Brewer, Clarence Edward Holmstadt
