Title: A data de-duplication system using chunks
Inventor: MOORHEAD PAUL
IPC: G06F3/06
Filed: 2012-08-10
Abstract: A data de-duplication system includes a data manager (12, fig. 1) for storing data blocks (40) in a memory 14 and an index for identifying which data blocks are stored in the memory (16) e.g. a sparse bitmap. The index includes chunks (22) e.g. of bits r corresponding to hash values of given data blocks, and a chunk allocation record (30) is provided which has a record of entries (32). Each record entry being associated with a range of data values that are associated with the data blocks, and being configurable to identify a respective chunk in respect of a received data block. The data manager refers to the record entry associated with the range of values in which the data value for the data block falls, and in the event that the record entry does not identify any of the chunks, selects one of the chunks, configures the record entry to identify the selected chunk, configures the selected chunk to identify the data value for the data block, and stores the data block in the memory. In the event that the record entry does identify one of the chunks, the data manager determines if the identified chunk is configured to identify the data value, and upon determining that the identified chunk does not identify the data value, configures the identified chunk to identify the data value for the data block, and stores the data block in the memory, and upon determining that said identified chunk does identify the data value, does not store the data block.

Filed: 2014-09-30
Abstract: A two-stage, fully self-retracting, telescopic fluid actuator suitable for high speed ejection applications comprises a detent 38, 64, 26, which locks a cylinder 6 in an extended position for extension of a piston 3 therefrom.

Title: Method and system for determining downhole optical fiber orientation and/or location
Inventor: FARHADIROUSHAN MAHMOUD
IPC: G01V9/00
Filed: 2014-10-29
Abstract: A probe 36a contacts the inner surface of a wellbore and imparts energy at the contact point. Energy may be imparted around the circumference of the wellbore and a fiber optic distributed sensor 56 located on the outer surface of the casing or other tubing is used to record the energy that it receives whilst the probe is moved. A record of energy versus position of the probe around the circumference can be obtained, from which maxima in the detected energy measurements can then be found. The position around the circumference which gave the maximum measurement should be the position at which the optical fiber of the fiber optic distributed sensor is located. This may allow a perforation gun to avoid damaging the optical fibres. The probe may be an acousto-vibrational tapper, a heated probe, or alternatively an electromagnetic projection device such as a laser. Alternatively the optical fibre may impart energy to the interior surface of the wellbore, and a sensor on a downhole tool in contact with the interior surface may detect the energy at a point of contact.
