Patent number: 9893984Abstract: Embodiments of the present invention provide path MTU discovery of a network path, such as an IPv4 network. According to various embodiments of the invention, a node receives a packet at a node along the network path between a source node and a destination node, compares a MTU size of a next hop along the network path with the size of the packet, responsive to the MTU size of the next hop along the network path being less than the size of the packet and responsive to the packet supporting path MTU discovery, the node truncates the packet to the MTU size of the next hop, stores the MTU size in the portion of the packet reserved for PMTU size, and forwards the packet.Type: GrantFiled: April 19, 2016Date of Patent: February 13, 2018Assignee: DELL PRODUCTS LPInventors: Chandra Mohan Sundar, Pugalendran Rajendran

Patent number: 9441686Abstract: A brake assembly includes a brake pad, a bracket supporting the brake pad and having a first portion, a second portion spaced apart from the first portion, and a linkage interconnecting the first and second portions. The linkage is configured to transfer tensile loads between the first and second portion, but is characterized by the absence of any bending modes. The absence of bending modes prevents excitation of the linkage, thereby reducing sound generated during application of the brake assembly.Type: GrantFiled: May 24, 2013Date of Patent: September 13, 2016Assignee: GM Global Technology Operations LLCInventors: Brent D.

Patent number: 9174274Abstract: A multi-piece sound dampened brake rotor comprises a relatively light weight hub with a hub flange and a heavier rotor body with a sound damping insert and a rotor body flange. The hub and rotor body are attached at their flanges. The flanges may be mechanically attached such as with bolts. Or the hub and rotor may be attached by casting the hub of a lower melting metal alloy against the rotor body and rotor body flange. The rotor body may have vanes for air cooling and a sound damping insert may be incased in either or both body portions sandwiching the vanes.Type: GrantFiled: July 31, 2008Date of Patent: November 3, 2015Assignee: GM Global Technology Operations LLCInventors: Michael D.

Patent number: 9027718Abstract: A light-weight, sound-damped, composite brake rotor for a vehicle braking system includes a rotor hat and an annular rotor cheek supported by, and cast around, the rotor hat. The rotor hat includes an axially-protruding central hub and an integral flange that extends radially from and circumferentially around the central hub. The rotor cheek includes a top ledge and a bottom ledge that overly a top annular surface and a bottom annular surface, respectively, of the integral flange. An annular interfacial boundary present between an underside of the top and/or bottom ledges and their respective adjacent annular surfaces of the integral flange includes a vibration damping interface. The brake rotor derives its vibration-deadening and sound-damping effects from the vibration damping interface through the occurrence of relative frictional contacting movement.Type: GrantFiled: August 31, 2011Date of Patent: May 12, 2015Assignee: GM Global Technology Operations LLCInventors: Michael D.

Patent number: 9016445Abstract: A light-weight and sound-damped brake rotor for a vehicle braking system includes a rotor hat and a rotor cheek supported by the rotor hat. The rotor hat includes an axially-protruding central hub and a flange that extends radially from and circumferentially around the central hub. The rotor cheek, which provides at least one braking surface, is formed from two or more separate and distinct pieces which are fixedly secured to the flange of the rotor hat. Located within the rotor cheek underneath the at least one braking surface is a vibration damping element.
