Patent number: 8811199Abstract: A first node sends a first message to a second node. The second node sends a second message to the first node. A first elapsed time is measured from the beginning of the transmission of the first message to the beginning of receipt of the second message. A second elapsed time is measured from the beginning of the receipt of the first message to the beginning of the transmission of the second message. The second node sends a third message to the first node containing the second elapsed time. The distance between the first and second node is calculated based on these elapsed times and a calibration count multiplier contained in the second or third message. A node may be moved within a wireless mesh network. Positional information about the node and distances to its neighbors is determined and transmitted to the network manager where it is stored.Type: GrantFiled: November 6, 2009Date of Patent: August 19, 2014Assignee: Rosemount Inc.Inventors: Mark Nixon, Robert Karschnia, Eric Rotvold, Trevor Duncan Schleiss, Deji Chen

Patent number: 7986968Abstract: A control system uses a wireless network to provide communication between a host computer and field devices. The host and the field devices communicate with one another using control messages and response messages based upon a known control system protocol. The control and response messages are embedded as a payload within a wireless message that is transmitted over the wireless network. When the wireless message is received at its ultimate destination, the control or response message is separated from the wireless message and is delivered to the intended recipient (either a field device or the host computer).Type: GrantFiled: January 11, 2007Date of Patent: July 26, 2011Assignee: Fisher-Rosemount Systems, Inc.Inventors: Patrick M. Dobrowski, Eric R. Lovegren, Kelly M. Orth, Kyle L. Stotz, Robert Karschnia

Publication number: 20080082180Abstract: A method and device or monitoring parameters in a process reduces power consumption and bandwidth requirements in the transmission of the monitored parameter to for example, a monitoring application. In particular, new monitoring parameter values are only transmitted if the difference between a measured or calculated parameter value and the most recently transmitted value exceeds a limit, since the last communication of the parameter or if the time since the last communication of the parameter exceeds a preset refresh period. The determination as to whether to transmit the parameter can be applied to engineering unit values or raw values.Type: ApplicationFiled: September 6, 2007Publication date: April 3, 2008Applicant: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Terrence Blevins, Robert Karschnia, Mark Nixon
