Title: Oceanic pump for removal of carbon dioxide from the atmosphere
Inventor: BIRKETT HAROLD
IPC: C02F3/20
Filed: 2012-01-23
Abstract: An oceanic biological pumping unit accelerates the photosynthesis in picophytoplankton and other microorganisms and thereby increases the amount of carbon dioxide absorbed into the sea. The unit also comprises electrolysis means which can separate seawater into hydrogen, oxygen and chlorine and smaller quantities of other gases. Gas bubbles produced by electrolysis can be injected into a flexible pipe 9 to induce an upward flow. One or more electric power generators 8 are preferably installed along the flexible pipe to extract energy from the upward flow. The flexible pipe may increase in diameter going upwards and may branch into several pipes to release aerated water and bacteria over a wider area. The unit may be operated in inland waterways by adding brine to the electrolysis unit. The brine can be added by a remotely operated control system. A mesh filter may be placed around the unit to protect against the ingress of unwanted debris.
Patent GB-2498720-A (GB)
Title: Detecting Movement of an Object Between a First and a Second Image
Inventor: VANDAME BENOA T
IPC: G06T7/20
Filed: 2012-01-24
Abstract: Movement of an object between first and second images is detected. A global distortion model (e.g. first order polynomial function modeling rotation, scale and translation) is determined based on the association of one or more points of interest in the first image with corresponding point(s) of interest in the second. Transformation (e.g. backward warping process) is performed on the second image (S22) to align it with the first based on the distortion model. A first observed residual between the first image and the transformed second image is computed (S23) and a predicted residual is computed (S26) based on a quantitative estimation of the variation of aliasing between pixels of the transformed second image (S24) and corresponding pixels of the first image, and on a quantitative evaluation of the level of aliasing within the first image based on the frequency of content detail of pixels of the first image (S25). The observed residual is compared with the predicted residual to identify pixels related to object movement. Sources of movement are therefore identified after removing the effect of variation of aliasing, allowing a more sensitive detection. An image sequence may be encoded using the movement detection method.
