System, head-mountable device and method for determining a value of a physiological parameter of an individual. The system comprises a head-mountable device intended to be worn by the individual. The head-mountable device comprises a first set of at least one sensor and a second set of at least one sensor. The at least one sensor of the first set comprises at least one LED and at least one photodiode. The at least one LED is arranged, so that light emitted by the at least one LED is reflected by the face of the individual and received by the at least one photodiode. Values outputted by the at least one sensor of the first set depend on an amount of the light received by the at least one photodiode. Values outputted by the at least one sensor of the second set depend on a distance between the face of the individual and the head-mountable device. The system is configured to determine the value of the physiological parameter of the individual based on values outputted by the at least one sensor of the first set and the values outputted by the at least one sensor of the second set.

A polymerizable composition for making thermosetting materials containing allylic monomers and/or oligomers and diisopropyl peroxydicarbonate (IPP) as an initiator, wherein the said composition comprises: • A UV absorber in an amount ranging from 0.1 to 2 % wt, • A phosphite based molecule in an amount ranging from 0.2% wt to 1% wt.

A manufacturing device for additively manufacturing an object, the object encapsulating a component, the manufacturing device being configured for placing the component in a volume of an optically reactive material, irradiating, for forming a part of the object, a part of the optically reactive material, the part of the optically reactive material being adjacent to the component, the irradiating being realized with a first light of a first wavelength and a second light of a second wavelength, wherein the irradiation of the part of the optically reactive material depends on a value of at least one characteristic of the component.

System and computer implemented method for determining updated values of manufacturing parameters to reduce defects in manufactured items. The system is configured for receiving descriptions of the defects, the descriptions being provided in a natural language, converting the descriptions into inputs suitable for a deterministic problem-solving module and feeding the inputs in the deterministic problem-solving module to obtain the updated values of the manufacturing parameters.

The invention relates to a method for making a polymerizable composition to produce an anti-abrasion hard coat which does not comprise adding organic solvent, the method consisting of (a) Stoichiometrically hydrolysing a tetraalkoxysilane compound bearing hydrolysable groups with HCl solution having a concentration between 0.025 to 0.05N to obtain a first composition; (b)Adding an epoxysilane monomer to the first composition; (c)Stirring the composition resulting from step (b); (d)Adding an excess amount of DI water for hydrolysing said epoxysilane, and lowering the HCl concentration under 0.025 mol.L^-1; (e)Adding a polymer catalyst under stirring.
