An automatic method of measuring the shape of plaster replicas of residual limbs has been developed. This instrument enables the full three-dimensional shape to be digitized and stored on computer. The shape modifications produced by student prosthetists are examined by requesting the computer to draw sections of the unmodified replica with corresponding sections following modification superimposed. This paper reports experiences with the use of this instrument as a teaching aid for student prosthetists.

This article examines the relatively new fields of colour and shape trade marks. It was initially feared by some academics that the new marks would encroach on the realms of patent and copyright.  However, the traditional requirements of trade mark law, such as functionality and descriptiveness, have meant that trade marks in colour and shape are extremely hard to acquire if they do not have factual distinctiveness. As colour and shape trade marks have no special restrictions, it is proposed that the combination trade mark theory and analysis from the Diamond T case should be used as a way to make them more accessible. The combination analysis can be easily applied because every product has a three dimensional shape and a fourth dimension of colour.
