Patent number: 10783026Abstract: An apparatus includes an interface configured to obtain data associated with multiple cables coupled to or forming a part of a redundant token bus control network. The apparatus also includes a traffic detector configured to determine whether valid data traffic is being received over the cables from the redundant token bus control network based on the data. The apparatus further includes at least one processing device configured to determine whether one or more of the cables has experienced a network fault or a return from a network fault based on the determination of whether valid data traffic is being received over the cables. The at least one processing device is also configured, in response to determining that one or more of the cables has experienced a network fault or a return from a network fault, to generate a notification that identifies the apparatus and the one or more cables and output the notification.Type: GrantFiled: February 15, 2018Date of Patent: September 22, 2020Assignee: Honeywell International Inc.Inventors: Jay W.

Patent number: 9448548Abstract: A method of displaying fault tolerant Ethernet (FTE) status in a process control system having FTE devices in a FTE community including a plurality of Enhanced Universal Control Networks (EUCNs) each having an Enhanced Network Interface Module (ENIM). FTE cable status data is collected from the FTE devices during system operation. Responsive to receiving user's request, generating diagnostic display view data filtered by a FTE Device index including FTE status for any combination of the FTE devices or second FTE diagnostic display view data filtered by EUCN node number including FTE status for FTE devices in a user selected EUCN. The first FTE diagnostic display view data or second FTE diagnostic display view data are transmitted to a device of the user, and is then displayed on a user's display.Type: GrantFiled: November 15, 2013Date of Patent: September 20, 2016Assignee: Honeywell International Inc.Inventors: Steven Roby, John Michael Prall, Laurence Clawson, Ronald E.

Patent number: 9306802Abstract: A method of displaying fault tolerant Ethernet (FTE) cable status in a process control system having FTE devices in an Enhanced Universal Control Network (EUCN) including an Enhanced Network Interface Module (ENIM) on a UCN status display. Updated FTE cable status is obtained from each of the FTE devices during operation of the process control system. The updated FTE cable status from each of the FTE devices is stored in a memory. A UCN cable status word (CSW) including cable status bits allocated for representing the updated FTE cable status is compiled for each of the FTE devices, wherein locations for the cable status bits in the UCN CSW are used by the UCN status display to show changes in cable status. The UCN CSWs are read at a node having the UCN status display, and the updated FTE cable status is displayed on the UCN status display.Type: GrantFiled: November 15, 2013Date of Patent: April 5, 2016Assignee: Honeywell International Inc.Inventors: Steven Roby, Basanth Chinivar, John Michael Prall, Michael Novak

Patent number: 8341256Abstract: A multi-generation distributed control system includes a first generation (FG) DCS connected to a local control network (LCN) including FG client nodes. A second generation (SG) DCS connected to a non-LCN data highway includes a server node connected between the LCN and the non-LCN data highway and SG client nodes. The server node includes a LCN processor (LCNP) board. LCNP emulator software including a server LCNP emulator software component is at the server node and a client LCNP emulator software component at the SG client nodes. The server LCNP emulator software component translates between LCN data and data highway protocol data and adds one of a plurality of LCN address slots to communications received from the LCN for delivery to the SG DCS that each correspond to a SG client node. Each client LCNP emulator software component provides one of the LCN address slots at its SG client node.Type: GrantFiled: November 11, 2010Date of Patent: December 25, 2012Assignee: Honeywell International Inc.Inventors: Rahul De, Anand Sunit, Nagore Hanifa Sikkandar Basha, Sakthivel Renganathan, Sarayu Subramanyam, Neha Parasharami, Ravi Gupta, Steven Roby, Piotr Golenko, Avinash Rajan, Vilas Ingle

Patent number: 8276186Abstract: A method for communicating data between a first and second control system (FCS and SCS). FCS (202) controls a first process (FP) having first security data (FSD) in a first data security format (FDSF). The method involves modifying the FSD (214) from being in the FDSF into modified security data (MSD) in a modified security format (MSDF) compatible with SCS (226). Subsequent to the modifying, a request is received from an SCS user. The request includes a user type, process parameter (PP) associated with the FP, and request for information regarding the PP or a request to change a PP value. The method also involves referencing the user type and PP to the MSD. The method further involves blocking or allowing the request based on results of the referencing. If results indicate that the request is allowed, then an access level can be impersonated for changing the PP value in FCS.Type: GrantFiled: January 22, 2008Date of Patent: September 25, 2012Assignee: Honeywell International Inc.Inventors: Leslie Lee DeFord, Steven Roby

Patent number: 6663347Abstract: A compressor wheel is re-designed to permit die inserts (20), which occupy the air passage and define the blades (4, 5) during a process of forming a wax pattern (21) of a compressor wheel, to be pulled without being impeded by the blades. This modified blade design enables the automated production of wax patterns (21) using simplified tooling. These wax patterns (21) can be used in a large-scale investment casting process, and produce an economical cast titanium compressor wheel which performs aerodynamically at high boost pressure/RPM. The compressor wheel improves low cycle fatigue, withstands high temperatures and temperature changes, and permits operation at high boost pressure ratio while, on the other hand, having low weight, low inertial drag, and high responsiveness.Type: GrantFiled: June 6, 2001Date of Patent: December 16, 2003Assignee: BorgWarner, Inc.Inventors: David Decker, Steven Roby

Patent number: 5773046Abstract: The invention relates to the method and apparatus for producing a cured elastomeric hose having an internal socket or other internal configuration formed therein. The invention also relates to the product produced according to the method and the apparatus. Cured elastomeric hose can be formed having an internal socket by mounting the hose on a mandrel assembly having the desired internal configuration formed therein. An end forming cap assembly is selectively mounted on the hose and mandrel assembly, tightly engages the hose and forces the hose to assume the shape of the mandrel assembly. The hose is cured and then the end forming cap is removed from the hose through the use of an air removal tool. The product produced according to this invention is suitable to receive a wide variety of articles such as an anti-splashback valve or a molded thermoplastic connector.Type: GrantFiled: August 30, 1996Date of Patent: June 30, 1998Assignee: Cadillac Rubber & Plastics, Inc.Inventor: H.
