There is described a portable wrist worn device for determining information about the movement of a human body when swimming. The device comprises a waterproof housing containing: an accelerometer operable to generate an acceleration signal; a processor operable to process the acceleration signal so as to generate one or more metrics relating to the movement of the human body; and a means for feedback of the one or more metrics to the user. The accelerometer may be operable to generate an acceleration signal along an axis parallel to the proximo-distal axis of the user's arm in use and/or the accelerometer may be operable to generate an acceleration signal along an axis parallel to the dorsal-palmar axis of the user's hand in use. The device may also be used in sports other than swimming.

Motion analysis device for sports

A sensor uses the principle of surface plasmon resonance (SPR) to monitor the progress of the reaction between a sample and a sensitive layer (for example an antibody layer). The layer is applied to the rear surface of a metallic film formed on the surface of an optically transmissive component in the form of a hemicylindrical lens and slide. Collimated light from a source is applied via a lens which focuses the incoming beam to a focus at a point to form a fan-shaped spread of light incident at the point. The light is internally reflected at the point, and emerges from the component to be applied to a dectector array which latter is electronically scanned. The angle of incidence of the light at the point is such as to span that angle which gives rise to surface plasmon resonance, together with a range of angles thereabout so that the progress of the resonant condition, as the reaction between the sample and the sensitive layer proceeds, can be monitored.
