Abstract: Video content enhancement methods, systems and devices are disclosed. An input video 11 is processed to generate an augmentation descriptor 4 from it, the augmentation descriptor 4 defining augmentations that enhance the content of the input video 11. An output video 14 is generated by combining the augmentations defined by the augmentation descriptor 4 with the input video 11, so that playback of the output video 14 features said augmentations. A timecoded transcript is generated from at least an audio portion of the input video 11, and the timecoded transcript is processed to generate from it a set of transcript-derived enhancements. The set of transcript-derived enhancements are added to the augmentation descriptor 4 as augmentations for enhancing the content of the input video 11.

Abstract: A device for providing a "soft shaft" interconnection between a prime mover and a driven machine, such as a turbine and an electric generator in a wind power plant, wherein the shafts of the two machines are coaxially aligned and are interconnected by a gearing, operatively connected to a hydraulic fluid pump/motor unit fitted between a high pressure accumulator and a low pressure accumulator in a hydraulic circuit so that the hydraulic circuit provides a predetermined torque dependency for the shaft interconnection. The gearing may be enclosed in a housing adapted to rotate about the shafts, the hydraulic unit being driven by the movements of the housing. Alternatively the hydraulic unit may be operated by a gear wheel meshing with a gear wheel, journalled in a stationary gearing housing.
