A bladder which is particularly useful for a sole assembly of a shoe is formed of multiple layers of barrier film to provide multiple pressurized layers of cushioning fluid or gas when the bladder is filled. A multiple gas layer bladder enhances cushioning response by relying more on the response characteristics of the gas and reducing the amount of foam and the dependence on foam as a cushioning material. The internal film layers provide a truss-like geometry in cross section and act as tensile members to impart a generally smooth surface contour to the bladder. The bladder is constructed to provide complex regionalized cushioning profiles which are coupled to the anatomy of the foot and expected loads at known points.

An extension indicator is provided for determining a predetermined extension applied to an extensibly deformable article such as medical bandage used in compression therapy. The indicator includes first ( ) and second ( ) co-operating members, each adapted to be secured to an extensibly deformable article ( ). One of the members is more extensible than the other and each member ( ) bears visual indicia ( ) which upon extension of the more extensible member, are adapted to align with each other to indicate a predetermined extension of the more extensible member.

Extension indicators

Particles are separated according to their dielectrophoretic characteristics and electrorotation characteristics by the use of a travelling wave separation in which they flow from a departure point at an inlet (,) towards at least two destinations at outlets (,) and are deflected toward one or other outlet according to their characteristics by a travelling wave field set up on an array of electrodes, each electrode running generally in the direction of flow.
