With the aid of the invention, small-linewidth structures can be created without high-precision lithography. | 01-15-2009 |
20090014655 | Coupling and Method for a Transition-Edge Bolometer - The invention relates to a circuit for transition-edge bolometers, which comprises a resistor element ( | 01-15-2009 |
20090011160 | Polymeric Packaging Film - A polymeric film has at least one surface on which chitosan has been immobilised so as to be substantially resistant to leaching and have a strong antimicrobial activity. The polymeric film may be a polyolefin film such as a biaxially orientated polypropylene film. A process immobilises chitosan on a polymeric surface so as to be resistant to leaching and have a strong antimicrobial activity by applying chitosan to a polymeric film surface which has been activated before addition of chitosan to the surface by plasma activation at atmospheric pressure. | 01-08-2009 |
20090006456 | CHARACTERIZING RUN-TIME PROPERTIES OF COMPUTING SYSTEM - A characterization system characterizes run-time properties of a computing system comprising hardware and software. The characterization system comprises generating means for generating an associative data structure comprising load data and priority data. The priority data characterize importance of a sub-process of a computer process during the execution of the computer process, and the load data characterize the use of resources of the computing system at an importance of the sub-process. | 01-01-2009 |

20080289120 | Method for Modifying Polyamide - The present invention relates to a method for modifying polyamide. The method comprises that polyamide is contacted with an enzyme preparation comprising an effective amount of protease enzyme in aqueous environment under conditions suitable for the function of the enzyme. The enzyme is preferably selected from the group of aspartic proteases, cysteine proteases and metallo-proteases. | 11-27-2008 |
20080283584 | Method and Terminal for Presenting in Speech Format Product Descriptions Attachable to Products - The invention is especially intended for visually impaired persons who are not able to read text printed on products or product containers. With the invented method at least a part of a product description, which corresponds to a bar code read and which is fetched from a product information database, is stored in at least one memory accessible to the terminal. After this, in response to a command ordered by a user of the terminal, the RFID identifier attached to the terminal is read and the product description is presented in speech format so that the information readable in the memory and the RFID identifier is utilized in the presentation. The terminal is preferably a mobile station equipped with a speech synthesizer. A visually impaired person can point with the terminal to one or more products and listen via an audio system of the terminal to the product descriptions related to them. When RFID identifiers are attached to the product, the products need to be pointed to as precisely when reading bar codes. The products are, for example, foodstuff or medicine. | 11-20-2008 |
20080262190 | Method For the Manufacture of Oligo- and Polyesters From a Mixture of Carboxylic Acid Obtained From Suberin and/or Cutin and Use Thereof - The invention relates to a method for processing mixtures of carboxylic acids obtained as hydrolysis products of suberin and cutin, particularly suberin and cutin isolated from birch bark, to give oligo- and polyesters, or corresponding ester-ethers, as well as the use of the products thus obtained as lubricants, fuel components, plasticizers, surface active agents, environmentally friendly agents for modifying wood, binders in coatings, adhesives, printing inks and composites, further in various cosmetic applications. | 10-23-2008 |
20080256824 | Method of Treating a Piece of Wood at an Elevated Temperature - The present invention relates to a method of heat treatment of a solid piece of wood, such as sawn timber. According to the method, the temperature difference between the inside temperature of the heating oven and, correspondingly, the inside temperature of the wood is maintained at a maximum of 10° C., after the level of moisture content of the piece of wood has reached the fibre saturation point of the wood. A small temperature difference such as this is maintained when the temperature is further increased until a level of moisture content is reached at which the strength properties of the piece of wood are at their best. By means of the solution it is possible to considerably reduce the formation of internal cracks in heat treated wood. | 10-23-2008 |
