Title: Filtering of seismic data to remove coherent noise from reflection data
Inventor: JI YING
IPC: G01V1/36
Filed: 2010-08-06
Abstract: A method of filtering seismic data, characterized in that the signals from sensors are filtered to attenuate coherent noise relative to reflection signals by attenuating received signals over one or more ranges of slowness. One example of coherent noise is ground roll, which has a typical slowness range of 0.001-0.005s/m. The seismic survey may be performed using single or point receiver arrays as this allows the recording of the output of individual sensors or receivers and the inherent filtering effect of the hard-wired group can be replaced by filters which preserve more of the seismic reflection signals, such as a multi-dimensional FIR digital filter. The invention adds linear constraints at some slowness ranges to keep the spatial aperture of the filter as small as possible by minimizing the weighted l-norm errors between the actual and the desired frequency slowness response.

Title: Interest Point Detection using downscaling and Hessian filtering
Inventor: KIRSCH GRAHAM
IPC: G06T1/20
Filed: 2011-01-18
Abstract: Interest points are markers anchored to a specific position in a digital image of an object. They are mathematically extracted in such a way that, in another image of the object, they will appear in the same position on the object, even though the object may be presented at a different position in the image, a different orientation, a different distance or under different lighting conditions. This application relates to identifying potential candidates for such points by the following means: Firstly image data is received and downscaled by blurring the image data, a Hessian or similar filter is then applied to the blurred data and then a Laplacian of Gaussians (LOG) or a Difference of Gaussians (DOG) or similar is use to identify the extrema in the filtered data. The data is then downscaled again and the filtering process repeated and the extrema again identified. This downscaling and filtering process may be repeated a number of times. The image data may be processed on a row by row basis with rows of data being discarded once they are no longer required for processing.

Title: A Deterministic version of the multiple point geostatistics simulation/reconstruction method
Inventor: MARIETHOZ GREGOIRE
IPC: G01V11/00
Filed: 2008-11-20
Abstract: A multiple-point geostatistics method of simulating, reconstructing and scaling digital data sets, in particular images, but not exclusively. The method of the invention is based on a training image that is directly sampled each time a point in the simulation image is to be filled, and does not need the preliminary creation of a data structure storing conditional probabilities, as it is often the case in known multipoint simulation method. Accordingly, the method of the invention is less memory-demanding than conventional methods, and is better suited to simulations including continuous variables. Embodiments regarding the application to reconstruction of partial images and downscaling are also presented.

Title: Providing a secure wireless link between two devices using a plurality of probes
Inventor: BRADLEY BOB
IPC: H04W12/06
Filed: 2011-08-30
Abstract: A secure wireless communication link (pairing) between two devices can be established using wireless transmissions between devices not joined to a network ("probes"). One device can broadcast a first probe indicating that it is seeking to establish a pairing. The other device can respond with a second probe, and the two devices can establish a shared secret, e.g., by exchanging further information using additional probes. A shared secret is established by exchanging public keys with a controller using a plurality of additional probes including at least a third probe sent by an accessory and a fourth probe received by the accessory, validating by the accessory that the shared secret is shared by the controller. The accessory then generates a further cryptographic key using the shared secret and receives a fifth probe from the controller which contains an encrypted message. Thereafter, either device can send a message to the other by encrypting the message using a cryptographic key derived from the shared secret; encrypted messages can also be sent within probes. The receiving device can extract an encrypted message from a probe and decrypt it using the cryptographic key. The encrypted message can include credentials usable by the receiving device to join a wireless network.
