Abstract: A device for monitoring surface alterations over time, preferably skin alterations, has means for capturing images of the alterations and for storing same in a memory. The device includes a screen and a processor for processing and managing said images, and the aforementioned image-capture means includes at least two cameras with overlapping viewing angles. The processor is configured to process skin alteration images taken from different angles and to obtain therefrom an image of said skin alteration that corresponds to a pre-determined viewing angle, lighting type and level and distance.

Abstract: The present invention relates to an inner cushion for helmets. The inner cushion includes an shock absorbing composite sandwiched between two protecting foils. The composite includes at least one absorbing material for absorbing an impact energy, wherein the at least one absorbing material is structured and arranged to absorb the impact energy by being crushed and collapsed upon exposure to the impact energy and diffusing air through a network of pores in the absorbing material.

Abstract: For the present we register a hybrid Inner Cushion for Helmets based on a Composite Foam sandwiched between two foils. The cushions or paddings used in the last century by helmets manufacturers (mainly made with expanded polystyrene, EPS or expanded polypropylene, EPP) absorb impacts by elastic deformation of the material, producing a significant bounce back after being compressed. The composite foams of the present invention avoid the ‘bounce back on head’ effect by converting a large fraction of the incoming kinetic energy in plastic deformation of the material. Thus, the ‘bounce effect’ or ‘counter-coup lesions’, which largely enhance the first impact brain damage, can be greatly reduced. Two covering foils, either made by a metal (i.e. aluminum) or a combination of a metal and a polymer (i.e. mylar), protect the cushion material against environment and other eventual damaging agents.

Abstract: An impact resistant helmet assembly having a first material layer coupled to a second material layer so as to define a gas chamber therebetween which contains a quantity that provides impact dampening upon an impact force being applied to the helmet assembly. The helmet assembly further includes a containment layer disposed over the second material layer and structured to define a fluid chamber in which a quantity of fluid is disposed. The fluid includes a generally viscous gel structured to provide some resistance against disbursement from an impacted region of the fluid chamber to non-impacted regions of the fluid chamber, thereby further enhance the impact distribution and dampening of the impact force provided by the helmet assembly.
