Publication number: 20130104852Abstract: A fuel rail has a mounting portion with an aperture through which a fastener extends along a central axis. The fastener secures the fuel rail with respect to a support surface. Stacked-layer isolators are positioned on both sides of the mounting portion. Each stacked-layer isolator includes a pair of rings and an elastomer layer positioned between the rings. Each elastomer layer has a pair of opposing contact surfaces respectively contacting adjacent contact surfaces of the corresponding pair of rings. The pairs of opposing contact surfaces of the elastomer layers and the contact surfaces of the pairs of rings are oblique to the central axis.Type: ApplicationFiled: October 28, 2011Publication date: May 2, 2013Applicant: Robert Bosch GmbHInventor: Venkatesh Kannan

Patent number: 8402947Abstract: A fuel rail includes an elongated tube having an inlet and a plurality of outlets. The elongated tube defines a fuel passageway for directing fuel toward the plurality of outlets. The fuel rail also includes a plurality of immovable baffles positioned within the elongated tube to divide the fuel passageway into a plurality of chambers such that each outlet is positioned in one of the plurality of chambers. The plurality of baffles restricts fluid flow between adjacent chambers. A majority of the plurality of outlets are located essentially at an acoustic node of each corresponding chamber to reduce noise generated by the fuel rail.Type: GrantFiled: June 22, 2012Date of Patent: March 26, 2013Assignee: Robert Bosch GmbHInventors: Venkatesh Kannan, Jason Schwanke, Chad D. Ormsbee, John P. Casari

Patent number: 8161945Abstract: A fuel injection system includes a fuel supply rail having a supply opening. A fuel injector is coupled to the fuel supply rail and configured to control the delivery of fuel from the fuel supply rail through the supply opening. A noise filtering device engages an upstream end of the fuel injector. The noise filtering device has a projecting portion extending at least partially into the supply opening along an axis, and the noise filtering device defines a restriction passage for directing fuel from the supply rail into the fuel injector. A face seal is established at a transverse face adjacent the supply opening.Type: GrantFiled: September 12, 2011Date of Patent: April 24, 2012Assignee: Robert Bosch GmbHInventors: Norbert Mueller, Venkatesh Kannan, Markus Friedrich, Jason L.

Patent number: 8121091Abstract: Described are systems, methods, and devices used for reducing scanning time while communicating between wireless mobile computing devices within a wireless communications network. The method includes the following step(s): receiving communication data from one or more APs within a network, the communication data being specific to each of the one or more APs and transmitting the communication data to an MU within the network. The MU is associated with a first AP and the MU associates with a second AP based on the communication data as the MU roams to the second AP. The method further includes the steps of: associating, by an MU, with a first AP within a network, receiving communication data from the first AP, the communication data including information specific to each of one or more further APs, and associating with one of the further APs based on the communication data.Type: GrantFiled: September 9, 2008Date of Patent: February 21, 2012Assignee: Symbol Technologies, Inc.Inventor: Venkatesh Kannan

Patent number: 8069842Abstract: An injector mounting arrangement includes a tolerance ring assembly that provides damping or absorption capabilities in addition to alignment and centering functionality. The tolerance ring assembly is designed to absorb axial excitation energy from the injector by converting it into strain energy through the radial deformation of the tolerance ring. The strain energy is absorbed in the form of bending stress within the tolerance ring more effectively than by simply absorbing the axial forces in compression alone. As a result, vibration and noise is reduced and/or isolated.Type: GrantFiled: July 2, 2009Date of Patent: December 6, 2011Assignee: Robert Bosch GmbHInventor: Venkatesh Kannan

Patent number: 8027248Abstract: An apparatus, network and techniques for minimizing wireless network downtime associated with a wireless switch failure are disclosed. Access ports are adopted to multiple wireless switches wherein one switch operates to exchange data and control traffic with the access port and remaining switches operate to exchange control traffic with the access port. In the event of a link failure between the wireless switch exchanging data and control traffic with the access port, the access port remains adopted to remaining switches and exchanges data and control traffic with one of the remaining switches.Type: GrantFiled: September 19, 2008Date of Patent: September 27, 2011Assignee: Symbol Technologies, Inc.Inventors: Karthikeyan Balasubramanian, Venkatesh Kannan, Shrijith Velayudhan, Vivek Krishnan, Somesh Agrawal
