Title: Methods and apparatus for an adaptive blocking matrix
Inventor: SAMUEL EBENEZER
IPC: H04R3/00
Filed: 2020-01-24
Abstract: A noise correlation statistic is estimated between two input signals 202,204. If the statistic meets a predefined condition then it is used to estimate an inter-sensor model h[n] that relates desired signal components present in the input signals. Otherwise, the model is estimated using a constrained statistic that is derived from the noise correlation statistic. The estimated inter-signal model 402 may then be used in an adaptive blocking matrix 210 to estimate noise signal b[n]. This noise signal may then be used (130, fig. 1) to perform adaptive cancellation on a beamformed signal derived from the input signals. More than two input signals may be treated similarly by estimating pairwise inter-sensor signal models. The condition on the noise correlation statistic may involve a maximum energy threshold of the normalised noise cross section, and the constrained statistic may be obtained by rescaling the noise correlation statistic by its norm.

Title: Post-quantum certificate binding
Inventor: MICHAEL W GRAY
IPC: H04L9/32
Filed: 2021-11-16
Abstract: The invention includes selecting a traditional certificate (such as X.509 standard) owned by an owner and calculating a fingerprint (such as a hash) of the traditional certificate. A post-quantum certificate is generated with identical information fields as the traditional certificate and the serial number of the post-quantum certificate is populated with the fingerprint. The post-quantum certificate acts as an extension of the first traditional certificate providing authentication and validation between a client and a server using post-quantum capable signing algorithms. The bound certificates can work in parallel without having to modify or replace the traditional certificate. The system may bind multiple certificates into a certificate chain, or generate a post-quantum certificate that is bound to more than one traditional chains instead of generating two separate post-quantum certificates. The invention may detect a vulnerable certificate containing a weak algorithm and generate a second post-quantum certificate using a second fingerprint.

Title: Shot point dithering techniques for marine seismic surveys
Inventor: EDWIN HODGES
IPC: G01V1/38
Filed: 2019-06-21
Abstract: A marine seismic survey uses shots at locations based on dither values which are subject to one one or more dithering constraints, including an absolute dither difference threshold constraint, a non-duplication constraint, and a statistical constraint. A set of nominal shot points for a marine seismic energy source and a set of dither values may be determined. A standard deviation of differences between dither values for consecutive shot points meets a threshold value. The dither values may be based on a velocity of the sources relative to the ground. This facilitates a de-blending procedure to separate signals from the marine seismic energy sources.
