Abstract: A jeweller's work bench accessory (14) for use with work bench fitments having an elongate shank (64). The accessory comprises structure (16) affixable to a work bench (10) and having an opening for receiving the shank (64) of the fitment. Releasable locking means is provided for locking the shank to the structure (16) when the shank is so received. The releasable locking means comprises an apertured member mounted within the structure (16) for receiving portion of the shank (64) when extended through the opening in the structure (16). The apertured member is then moveable downwardly with respect to the shank (64) for gripping of the shank (64) between portions of the structure (16) and member which surround the opening and aperture respectively. Rotatable means (28) is provided for effecting the downward movement of the member.

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.
