Abstract: Among other things, a user of a browser is exposed simultaneously to three interfaces: A viewing interface for at least one image of a subject that is stored on a device on which the browser is running, a decision support interface that aids the user in determining the state of the subject based on the image, and a template interface that aids the user in capturing uniform descriptive information about the state of the subject. At least two of the viewing interface, the decision support interface, and the template interface operate cooperatively so that actions of the user with respect to one of the two interfaces causes changes in content exposed by the other of the two interfaces.

Abstract: A sole adapted to provide improved leverage during the toe-off stage of gait comprises elongate elements (2a-e) along the horizontal surface of the sole. The elongate elements (2a-e) are adapted to tauten in response to longitudinal forces on the sole, increasing the rigidity of the midsection of the sole and providing effective propulsive assistance to the athlete.

Abstract: A diagnostic device comprises a container formed from a base element (10) and a cover element (11) bonded together to define a cavity. The cover element is formed with an aperture (17) surrounded by a depression (18) and a single or multi-layer porous support membrane (9) located within the cavity so as to be accessible through the aperture. A body of fluid-absorbent material (14) is also located within the cavity in contact with the porous support. The fluid-absorbent material (14) is formed at least partly from fibers of a kind which absorb fluid into the fiber itself, so as to cause the fiber to swell and increase in volume. Appropriate reactants are applied to the porous support (9) so that when a sample to be tested is applied to the support through the aperture (17) the result of any reaction can be observed. Samples or reactants in the form of fluids pass through the porous support and are absorbed by the underlying body (14) of fluid-absorbent material.
