Patent number: 4562539Abstract: A data processing system comprising multiple processing nodes each containing a processor and a data store. The store holds local data, and also holds copies of shared data required by the node. This reduces conflict between the nodes in accessing the shared data. When one node updates the shared data, it sends an update message to all the other nodes over a transmission link. The processor is then free to continue processing. When the message reaches the other nodes, it updates the other copies of the shared data, so as to ensure consistency. Each node receives messages from the link in the same order, and this defines a unique chronological order for the updates, even though the nodes are asynchronous. A node is temporarily suspended if an update occurs out of this correct chronological order.Type: GrantFiled: February 17, 1983Date of Patent: December 31, 1985Assignee: International Computers LimitedInventor: Nigel L. Vince

Patent number: 4560595Abstract: The thermal emission characteristics of sheet form camouflage material is predetermined to match closely the known thermal emission characteristics of the natural environment in which the particular camouflage material is intended to be used. This control is accomplished by the combination of a reflecting thin metallic layer covered on at least the exposed side by a layer of plastic material comprising at least two different plastic materials each having different emissivity properties. The reflecting layer both minimizes the heating of the camouflage material from sources covered by the material and reflects incident heat from meteorological sources such as solar warming and the plastic layer controls and determines the radiation of heat from all parts of the exposed surface of the camouflage to present to surveillance equipment a thermal-picture closely simulating that of the surrounding terrain.Type: GrantFiled: March 22, 1984Date of Patent: December 24, 1985Assignee: Diab-Barracuda ABInventor: Lars E. Johansson
