Patent number: 11888740Abstract: Techniques for integrating disparate headend traffic ingress services with disparate backend services are disclosed herein. The techniques may include receiving, at a classification and forwarding node of a networked computing environment, a data packet encapsulated according to a first encapsulation protocol that is supported by the classification and forwarding node. The techniques may also include determining, by the classification and forwarding node, that the data packet is to be sent to a service from among a group of services associated with the networked computing environment. The classification and forwarding node may also determine whether the first encapsulation protocol is supported by the service. Based at least in part on determining that the service supports a second encapsulation protocol different than the first encapsulation protocol, the classification and forwarding node may encapsulate the data packet according to the second encapsulation protocol and send the data packet to the service.Type: GrantFiled: March 5, 2021Date of Patent: January 30, 2024Assignee: Cisco Technology, Inc.Inventors: Leonardo Rangel Augusto, Stephen John Hassard, Kyle Andrew Donald Mestery, Bernardo De Moraes Soares

Patent number: 7413642Abstract: A separating device for use in separating electrically charged components, e.g., by electrophoresis, comprises a channel branched at a branch point to provide a main feed channel (105) connected to at least two subsidiary channels (110, 115). In use, different components (120, 125, 130) show differential migration along the feed channel (105) so they can be separated into different subsidiary channels (110, 115) at the branch point. To support this separation, the separating device is provided with switchable voltage control means for controlling local voltages in a region of the branch point to provide potential differences of opposing polarity along the respective subsidiary channels (110, 115) such that a component to be separated (125) can be caused to migrate from the feed channel into a different subsidiary channel (115) from one or more other components.Type: GrantFiled: July 8, 2003Date of Patent: August 19, 2008Assignee: Deltadot LimitedInventors: John Hassard, Ed McKigney

Patent number: 7372038Abstract: An apparatus and method for analysing temperature-dependent molecular configurations such as folding comprises a multi-channel flow-through chip (12) along which molecules to be analysed pass. A temperature gradient is maintained along the length of the chip. As molecules pass along the channels they fold or unfold, in response to the changing temperature. These changing molecular configurations are investigated by simultaneously measuring the extent to which the molecules absorb UV light, and the extent to which they fluoresce. The absorption and fluorescence information is supplied to a computer system (26) for real-time analysis.Type: GrantFiled: October 3, 2002Date of Patent: May 13, 2008Assignee: Deltadot LimitedInventors: John Hassard, Anthony Edward George Cass

Patent number: 7132758Abstract: An apparatus for extracting power from a fluid flow comprises a fluid driveable engine, a conduit, disposed to enable fluid communication between a portion of the fluid flow, the fluid driveable engine and a transmission fluid, the fluid in the fluid flow and the transmission fluid being different fluids and the portion of the fluid flow being at a lower pressure than the transmission fluid by virtue of its flow rate, thus causing the transmission fluid to be drawn through the conduit to become entrained in the fluid flow, the fluid driveable engine being arranged such that the flow of the transmission fluid along the conduit acts to drive the fluid driveable engine.Type: GrantFiled: March 19, 2003Date of Patent: November 7, 2006Assignee: Hydroventuri LimitedInventors: Geoffrey Kenneth Rochester, Keith Pullen, John Hassard

Patent number: 6979390Abstract: A system for separating biological molecules includes a chip (10) on which there is an electrophoresis separation microchannel (16). At the start of the channel there is an isoelectric focusing section (14) containing a gel having a pH gradient. Molecules to be separated are placed in the focusing section (14) and move to an equilibrium position under the influence of an electric field. The electrophoretic state of the molecules is then changed, and a high voltage potential applied across the entire length of the focusing and separation sections. The molecules migrate under the influence of the electric field from the focusing section into the separation section where their position and velocity are tracked. From a knowledge of position and velocity, a user can determine both charge/mass ratio and isoelectric equilibrium point for each molecule. The gels can be replicated in the chip to allow parallel analysis, and hence comparisons, to take place.Type: GrantFiled: October 23, 2001Date of Patent: December 27, 2005Assignee: Deltadot LimitedInventors: Giles Hugo William Sanders, John Hassard, Stuart Hassard, Dimitrios Sideris

Patent number: 6752914Abstract: An analyser comprises a substrate (20) of diamond, sapphire or a polymer material; an array (10) of elongate capillary channels formed in the substrate; means (40) for driving a sample to be tested along one or more of the channels whereby the velocities of components of the sample along the channels depends on the relative molecular weights of those components; and a radiation source (100) and a radiation detector (30) disposed on either side of the channel array so as to detect the presence of material in the channels as interruptions in the radiation path between the radiation source and the radiation detector.Type: GrantFiled: November 15, 2000Date of Patent: June 22, 2004Assignee: Deltadot LimitedInventor: John Hassard
