  • Patent number: 8641590
    Abstract: A sheet folder comprising input rollers, exit rollers and a fold box having a fold plate which is curved substantially along its whole length, wherein the curved fold plate is configured to induce a sheet to curve in two different directions during the folding process.
    Type: Grant

  • Patent number: 7675655
    Abstract: Apparatus for scanning a moving object includes a visible waveband sensor 12 oriented to collect a series of images of the object as it passes through a field of view 16. An image processor 14 uses the series of images to form a composite image. The image processor 14 stores image pixel data for a current image and a predecessor image in the series. It uses information in the current image and its predecessor to analyse images and derive likelihood measures indicating probabilities that current image pixels correspond to parts of the object. The image processor 14 estimates motion between the current image and its predecessor from likelihood weighted pixels. It generates the composite image from frames positioned according to respective estimates of object image motion. Image motion may alternatively be detected by a speed sensor such as a Doppler radar 200 sensing object motion directly and providing image timing signals.
