Patent number: 6596469Abstract: A method of making a mask or an electronic part, for example a printed circuit, comprises the steps of delivering heat in a desired pattern to a precursor of the mask or electronic part, the precursor comprising a surface coated with a coating, the coating comprising a heat-sensitive composition itself comprising an aqueous developer soluble polymeric substance and a compound which reduces the aqueous developer solubility of the polymeric substance, wherein the aqueous developer solubility of the composition is not increased by incident UV radiation but is increased by the delivery of heat; then developing the precursor to remove the heat-sensitive composition in regions to which the heat was delivered. In the case of a printed circuit precursor the surface may be then etched in conventional manner to yield the required printed circuit.Type: GrantFiled: February 11, 2000Date of Patent: July 22, 2003Assignee: Kodak Polychrome Graphics, LLCInventors: Christopher David McCullough, Kevin Barry Ray, Alan Stanley Victor Monk, John David Riches, Anthony Paul Kitson, Gareth Rhodri Parsons, David Stephen Riley, Peter Andrew Reath Bennett, Richard David Hoare

Publication number: 20030103450Abstract: The present invention relates to a switch for processing data units, such as IF data packets. The switch can be implemented as a router that includes a plurality of input ports, a plurality of output ports and a switch fabric capable of establishing logical pathways to interconnect a certain input port with a certain output port. A characterizing element of the router is its ability to control bandwidth usage on a basis of a logical pathway. This prevents congestion to occur in the switch fabric and also at the level of the output ports. For every active logical pathway the router sets-up a bandwidth control mechanism including at least one queue to hold data units received at an input port. The bandwidth control mechanism performs an accounting operation to determine the average bandwidth usage and if less than a threshold requests for releasing data units in the switch fabric are sent to the switch fabric controller.Type: ApplicationFiled: April 30, 1998Publication date: June 5, 2003Inventors: ALAN STANLEY JOHN CHAPMAN, HSIANG-TSUNG KUNG

Patent number: 6524767Abstract: An imagable article comprises a thermally imagable coating on a substrate, the coating comprising a radiation absorbing compound and a metal compound which is thermally decomposable, to form a metal. The imagable article is imagewise exposed to electromagnetic radiation, which is converted to heat by the radiation absorbing compound. The imaged article is then subjected to a developer, and in regions that have been exposed the thermally decomposable metal compound is decomposed to elemental metal, and regions that have not been exposed dissolve in the developer leaving behind the regions of elemental metal.Type: GrantFiled: October 26, 2000Date of Patent: February 25, 2003Assignee: Kodak Polychrome Graphics LLCInventors: Kevin Barry Ray, Anthony Paul Kitson, Alan Stanley Victor Monk

Patent number: 6493316Abstract: Flow control of packet based traffic by window is known. Novel modification is described which causes the flow control mechanism to reduce sending rate to some configured number rather than just reducing it by a fixed amount such as one half. The description also shows how the flow control mechanism can be constrained to a maximum rate. The configured numbers will assure that the connection can always run at a minimum rate but not more than a maximum rate. If the guaranteed minimum bandwidth is known and the round trip time between the end points is known or has been calculated, then the sender node needs only reduce its window to that which corresponds to a sending rate equal to that configured number. In this way the protocol will still probe for extra, opportunistic bandwidth but will be able to maintain the minimum rate. In a similar way a window that corresponds to the maximum rate can be calculated and used to constrain the maximum rate of sending.Type: GrantFiled: December 1, 1998Date of Patent: December 10, 2002Assignee: Nortel Networks LimitedInventors: Alan Stanley John Chapman, Hsiang-Tsung Kung

Patent number: 6485890Abstract: Thermally imageable lithographic printing plate precursors and heat-sensitive compositions for use in these printing plate precursors are disclosed. The compositions contain an aqueous developer soluble polymer, such as a phenolic resin; a compound that reduces the aqueous developer solubility of the polymer; and optionally, and infrared absorber. Examples of compounds that reduce the aqueous developer solubility of the polymer are those that contain at least one quarternized nitrogen atom, such as quinolinium compounds, benzothiazolium compounds, pyridinium compounds, and imidazoline compounds. On thermal imaging, the irradiated areas become more soluble in the aqueous developer and can be removed to form a positive image.Type: GrantFiled: May 18, 2001Date of Patent: November 26, 2002Assignee: Kodak Polychrome Graphics, LLCInventors: Gareth Rhodri Parsons, David Stephen Riley, Richard David Hoare, Alan Stanley Victor Monk

Publication number: 20020101834Abstract: Methods for modeling costs of wireless network infrastructure are described. More specifically, the cost contribution models for modeling radioports are described. Various radioport architectures include a constant channel capacity model (48) and a constant offered load model (82). Under constraints imposed by a class of dense user networks, such as wireless metropolitan area networks, cost models are shown to exhibit convex cost functions having minimums. Processes for analyzing these cost models are described for determining which radioport architecture, provides a least-cost radioport cost segment to the overall network cost.Type: ApplicationFiled: December 7, 2000Publication date: August 1, 2002Inventor: Richard Alan Stanley

Patent number: 6330226Abstract: Congestion at a network node can be aggravated by having too many TCP connections. A simple method of avoiding the bad effects of too many TCP connections is to limit the number of connections. Limiting the number of connections is achieved by an admission control which delays or even discards the connection set-up packets. TCP traffic flows are monitored to generate packet loss characteristics and when a certain condition is met, a connection request queue is disabled.Type: GrantFiled: January 27, 1998Date of Patent: December 11, 2001Assignee: Nortel Networks LimitedInventors: Alan Stanley John Chapman, Hsiang-Tsung Kung

Patent number: 6304552Abstract: The present invention relates to a lossy switch for processing data units, for example IP data packets. The switch can be implemented as a contained network that includes a plurality of input ports, a plurality of output ports and a lossy switch fabric capable of establishing logical pathways to interconnect a certain input port with a certain output port. A characterizing element of the switch is its ability to control the discard of data packets at a transport point within the switch. This control mechanism prevents and reduces congestion which may occur within the switch fabric and at the level of the input and output ports. The system also supports priorities, routing HI priority request data packets over the switch fabric before LO priority request data packets, and discarding LO priority data packets first when controlling congestion.Type: GrantFiled: September 11, 1998Date of Patent: October 16, 2001Assignee: Nortel Networks LimitedInventors: Alan Stanley John Chapman, Hsiang T.
