Publication number: 20120186218Abstract: A pneumatic tire for use on aircraft has a tread, a crown reinforcement, and a radial carcass reinforcement having at least one axially inner ply of textile cords wound around a pair of bead cores, at least one axially inner ply being wound around the bead core in each bead from inside to the outside forming outside turn-ups and at least one axially outer ply of textile cords extending from bead to bead along the turn-ups of the at least one axially inner ply. The at least one axially inner ply or at least one axially outer ply has merged cords having a percent elongation at break of 12% to less than 20% and a break strength greater than 1050 N with a linear density of greater than 9,000 dtex. Merged cord reinforcement is preferably used in the ply layers or strips of the crown reinforcement as well.Type: ApplicationFiled: April 3, 2012Publication date: July 26, 2012Applicant: THE GOODYEAR TIRE & RUBBER COMPANYInventors: Walter Kevin Westgate, Yuvaraj Senthil Arumugam, Robert John Gartland

Patent number: 8036202Abstract: Disclosed, inter alia, is a Physical Layer Transceiver (PHY) with integrated time synchronization, such as, but not limited to, IEEE 1588 Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems. The PHY includes circuitry to maintain a current time, and to trigger the storage of timestamps corresponding to received frames. Typically, in response to a request from an external device, the timestamps are retrieved from storage and are communicated to the external device. By moving the triggering of the storage of the timestamps by the PHY itself, rather than by a monitoring of the traffic between the PHY and the Media Access Controller (MAC), higher accuracy can typically be achieved.Type: GrantFiled: July 27, 2006Date of Patent: October 11, 2011Assignee: Cisco Technology, Inc.Inventors: Daniel Christian Biederman, Haichuan Tan, Howard Borchew, Senthil Arumugam

Patent number: 7885296Abstract: Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for maintaining consistency among timestamp counters distributed among multiple devices. When timestamp counters are distributed among multiple physical devices, variances in their timestamp values can occur, such as, but not limited to those cause by variances among clocks in these different devices, different routing delays, different components, etc. These differences may be same, but still not allow high enough precision, especially as packet and processing rates continue to increase (which also causes clocking rates of devices to increase). One implementation distributes a time advance signal to each of these devices, which each device independently uses to determine when to advance its timestamp counter in response to its clock signal.Type: GrantFiled: July 27, 2006Date of Patent: February 8, 2011Assignee: Cisco Technology, Inc.Inventors: Daniel Christian Biederman, Haichuan Tan, Senthil Arumugam, Howard Borchew

Publication number: 20100024948Abstract: This invention disclosed a pneumatic tire for use on aircrafts having a tread, a crown reinforcement, and a radial carcass reinforcement. The carcass reinforcement has at least one axially inner ply of textile cord wound around a pair of bead cores, at least one axially inner ply being wound around the bead core in each bead from inside to the outside forming outside turn-ups and at least one axially outer ply of textile cords extending from bead to bead along the turn-ups of the at least one axially inner ply. Each bead has an elastomeric apex filler. The at least one axially inner ply or at least one axially outer ply has merged cords having a percent elongation at break of 12% to less than 20% and a break strength greater than 1050 N with a linear density of greater than 9,000 dtex. The preferred cord has fibers of polyamide and nylon. The cord fiber of polyamide is an aromatic polyamide 3300/2 construction. The cord fiber of nylon is a 1880/1 nylon construction. The preferred cord construction is 6.Type: ApplicationFiled: October 30, 2008Publication date: February 4, 2010Applicant: THE GOODYEAR TIRE & RUBBER COMPANYInventors: Walter Kevin Westgate, Yuvaraj Senthil Arumugam, Robert John Gartland
