Title: Cache coherency between a CPU cache hierarchy and a graphics cache hierarchy
Inventor: OFFEN ZEEV
IPC: G06F12/08
Filed: 2009-03-27
Abstract: A processor 101, such as a central processing unit (CPU), is in a cache coherency domain with a first set of coherency rules 109. A graphics device 105, such as a graphics processing unit (GPU), is in a different coherency domain 111 with a second set of coherency rules. The processor has a level 1 processor cache 103 (L1 cache) and a lower level processor cache 107. The graphics device has a level 1 graphics cache 104 (L1 cache) and a lower level graphics cache 108. The central processing unit uses the first set of coherency rules with the lower level graphics cache. The graphics device uses the second set of coherency rules with the lower level graphics cache. The lower level graphics cache may be a mid-level or last level cache. The processor may snoop the lower level graphics cache.

Title: Device for detecting flooding of a hollow structure
Inventor: GEORGE DAVID
IPC: G01F23/296
Filed: 2013-01-16
Abstract: A device for detecting the presence of liquid 25 in a hollow structure, such as a supporting member of an off-shore oil rig, is disclosed. It comprises an ultrasonic generator for emitting ultrasound toward an outer surface of a wall of the structure; an ultrasonic detector; a processor which controls the ultrasonic transducer so as to emit ultrasound and for controlling the detector so as to detect reflections 24 between the outer surface and an inner surface of the same wall 14. The processor determines from the reflections an indication as to whether or not liquid exists within the structure. The presence of liquid is preferably determined by measuring the rate of decay between at least two peaks, and comparing it to a previously determined rate, perhaps measured for a structure with no liquid opposite the device. The generator may emit at least one burst of ultrasound, which may contain a number of cycles.

Title: Hydrocarbon recovery employing an injection well and a production well having multiple tubing strings with active feedback control
Inventor: STONE TERRY WAYNE
IPC: E21B43/12
Filed: 2012-08-08
Abstract: System and method for producing fluids from a hydrocarbon reservoir where an injector well segment and parallel underlying producer well segment are both completed with slotted liners. The injector and producer segments are logically partitioned into corresponding sections to define a plurality of injector-producer section pairs. Injection tubing strings supply stimulating fluid (e.g., saturated steam) to associated sections of the injector segment for injection into the hydrocarbon reservoir.

Title: System and method to prevent misuse of aircraft messages
Inventor: SAMPIGETHAYA RADHAKRISHNA G
IPC: H04K1/02
Filed: 2014-03-11
Abstract: Aircraft signal transmission comprising transmitted data has false information introduced into it so that the transmitted data includes true and false aircraft position and movement information. Thus an avionics system may include an automatic dependent surveillance-broadcast (ADS-B) transponder 20 to generate ADS-B Out messages 21 and an airborne ATC processor 25 which causes the transponder to transmit authorised bogus ADS-B Out messages 24 which are recognized as false only by authorized users 22. The bogus flight trajectory may be generated so as not to conflict with trajectories of neighbouring aircraft. The airborne processor may also detect maliciously spoofed ADS-B Out messages 28. Thus misuse of ADS-B Out information for malicious cyber or physical attack is prevented.

Patent GB-2541034-A (GB)
Title: Network operation
Inventor: ALEXANDER HEALING
IPC: G06F17/30
Filed: 2015-08-12
Abstract: Modern communications networks produce vast amounts of network operational data which have the potential to provide a useful summary of the operational state of the network. Whilst processes such as clustering are known for arranging the vast amount of data into groups, the clusters themselves do not provide data which might be easily interpreted by network elements or administrators. Network operational data often comprises a plurality of data items, each of which gives a value for each of a set of attributes. By processing a cluster to identify attributes in the cluster whose values vary less in the cluster then they vary outside of the cluster, and then generating a cluster description which is based on a measure of the central tendency, e.g. the modal value or the mean value, of the values of those attribute in the cluster, an easily interpretable general description of the data items in the cluster is provided. The easily interpretable general description of the cluster can then be used to relatively identify data items similar to those present in the cluster (e.g. from a larger database of data items), and elements in the network can then act autonomously on the basis of the cluster description to control the operation of the communications network.
