  • Patent number: 10071220
    Abstract: In summary the invention relates to a stimuli control system configured for finding ambient stimuli from a database in a way so that the ambient stimuli having the most promising effect on stress reduction is selected. The selection may be performed based on a probability distribution created for describing how likely it is that a given ambient stimuli has a positive effect on the stress level for a given patient or other user. The database is a multiuser database which may be updated based on experiences from users' already registered ambient stimuli.

  • Patent number: 9346730
    Abstract: A process for producing furfural and levulinic acid from lignocellulose-comprising biomass is disclosed. The biomass is slurried using water and optionally an acid, subjected to hydrolysis, and then subjected to a solid/liquid separation to yield at least an aqueous fraction comprising C5 and C6 sugars and a solid fraction comprising cellulose and lignin. Furfural is obtained by adding an organic solvent to the aqueous fraction, heating at 120-220° C. for a sufficient time to form furfural, cooling, and separating an organic phase comprising at least part of the furfural from an aqueous phase. Levulinic acid is obtained by suspending the solid fraction in water and optionally an acid, heating the suspension to 140-220° C., and separating an aqueous fraction comprising the levulinic acid from a solid fraction.
