  • Patent number: 10012491
    Abstract: A diffraction interferometer includes a reference light passage, a test light passage and a pinhole substrate. The pinhole substrate includes a test pinhole and a reference pinhole. The diffracted wavefront emitted from the test pinhole is reflected by the optical component to be tested adjacent to the pinhole substrate and a converge adjacent to the reference pinhole. The diffracted wavefront includes surface shape information of an optical component to be tested that is reflected by the pinhole substrate. Interference with the diffracted wavefront is emitted by the reference pinhole and forms interference fringes. The large numerical aperture phase-shifting dual pinhole diffraction interferometer adopts a dual pinhole substrate and a illumination manner with two converged light paths to enable the separation of the reference light and test light, to prevent disturbance between the two light paths, which would induce the change of interferogram status during phase-shifting.

  • Patent number: 9902815
    Abstract: In this study, commercially available softwood lignin was esterified with tall oil fatty acid (TOFA) and tested as barrier material in fiber-based packaging material. The modified lignin samples were applied with a bar coater forming an even coating on the paperboard substrate. A significant decrease in WVTR and OTR value was observed for paperboard coated with the modified lignin as well as pure TOFA used as a reference. In contrast to the TOFA coating, the modified lignin coatings exhibited a high and stable contact angle. The coating material did not affect the tensile strength of the paperboard. According to the results, the demonstration of the conversion of lignin into a value added product has been shown. Furthermore, the novel coating material shows promising properties for the development as sustainable barrier material in fiber-based packaging material to replace oil-placed barriers.

  • Patent number: 9882790
    Abstract: Recommendation system based on the actions of a group of users, and not requiring prior metadata, is provided. The recommendation is not limited to from user-to-item (e.g. media recommendation) type; e.g. from user-to-user (e.g. social networking), from item-to-item (e.g. “see also” in internet shopping) and item-to-user (e.g. advertizing) recommendations are supported. The solution utilizes a set of identifiable tokens, associated with each entity, an entity being either a user or an item. Whenever there is an interaction between entities, either existing token sets are updated or new token sets are created such that after an interaction each interacting entity is associated with a token set which resembles more than before the token set(s) associated with the other interacting entity. Recommendation can be produced by searching best matching token sets on the user-to-item, user-to-user, from item-to-item or item-to-user basis.
