The disclosure relates to seamless manufacturing processes for 3-dimensional waterproof and breathable porous polymer membranes by spraying, dip-coating or painting a substrate with a dispersion having polymer, coated or non-coated particles and diluent and removing the particles by dissolution thus creating porosity after the 3D coating/shaping. The disclosure further relates to dispersions to obtain such membranes, to polymer membranes obtained, to shaped articles containing such membranes; to the use of such membranes, shaped articles and intermediates.

A device is provided for locating a moving object or person in a space partially equipped with inductive surfaces. The device comprises magnetic detection means configured to detect the presence of the object or of the person on or close to an inductive surface, measure a heading angle by way of two simultaneous measurement points and generate dated reference heading angle data for the object or for the person; inertial detection means configured to generate estimated angular speed and acceleration data for the object or for the person; and calculation means coupled to the magnetic and inertial detection means, configured to combine the dated reference heading angle data with the estimated data in order to generated corrected position and orientation data for the object or for the person in the space.

To provide a sports inner boot that ensures removal from a sports outer boot to allow an inside to be easily washed and where a drying time be a comparatively short time. A sports inner boot made of a thermoplastic plastic includes a bottom plate disposed in the sports outer boot and a foot wrap portion formed at the bottom plate. The bottom plate and the foot wrap portion are integrally formed. The bottom plate and the foot wrap portion contain an ethylene vinyl acetate copolymer material (EVA).

A medical shoe having a plurality of outsole projections is provided. The medical shoe may include a sole assembly configured to support a foot, and a frame surrounding the sole assembly. The sole assembly may include a midsole portion forming a substantially planar surface for supporting the foot and an outsole portion including the plurality of outsole projections extending from the midsole portion. The frame may include a plurality of through holes corresponding to the plurality of outsole projections. The plurality of outsole projections may extend through the plurality of through holes so as to form a ground contacting surface. The plurality of outsole projections may also be provided in a symmetrical pattern. The sole assembly may be secured to the frame by a self-locking fit between the sole assembly and the frame.
