Abstract: A method for the biological treatment of organic waste containing impurities consisting of non-biodegradable materials, including: • a first step of wet mechanical separation of the non-biodegradable materials present in the abovementioned organic waste in order to obtain a purified organic fraction, • a second step of dehydrating the purified organic fraction in order to obtain a dehydrated purified organic fraction and an effluent, • a third step of dry anaerobic biological treatment of the dehydrated organic fraction in order to obtain organic residues.

Abstract: There are described methods and apparatus for scrambling digital content, such as video or audio content, by dividing the digital content into blocks set out in an original arrangement, and reordering the blocks from the original arrangement to a scrambled arrangement. Additional manipulation transforms such as rotations and reflections may be applied to individual blocks. A subsequent compression step may then be carried out. Methods and apparatus for carrying out corresponding descrambling of digital content are also described.

Abstract: Systems and methods for estimating distances to objects or features are described. The distance estimation tracks features across images captured from a single camera mounted to an automobile and determines features that are off-ground. Features are tracked based on a ground motion estimate and respective motion of the features tracked across two or more successive images. For each off-ground feature a distance to the camera is calculated based on motion of the feature in the images captured by the camera projected to a ground-plane and the ground motion estimate.
