| 20100250457 | AUTHENTICATION ITEM AND SYSTEM FOR PACKAGED ARTICLES AND METHOD FOR THE MANUFACTURING OF THE AUTHENTICATION ITEM - The present invention discloses, inter alia, an authentication item manufactured on product units for encoding the product units as being authentic. The authentication item is an intensity-modulating surface comprising a plurality of adjacent protrusions such that the intensity-modulating surface has alternating height. Each of the protrusions has at least two slopes of respective different orientation. When being in an authenticating position with respect to incident electromagnetic radiation employed for authentication, the authentication item modulates the intensity of the electromagnetic radiation in a manner that generates an intensity profile which is characteristic of the authentication item. In the authentication position, the propagation direction of the incident electromagnetic radiation is at least approximately parallel to one of the at least two slopes of the plurality of protrusions. | 09-30-2010 |
| 20100242629 | ROLL-TO-ROLL COMPATIBLE PRESSURE SENSITIVE EVENT SENSING LABEL - The present invention discloses a smart label to be affixed on or integrated in an object and able to provide an electrical signal indicative of the applied pressure or force and/or the position of the applied pressure or force at a touch point on the object to which the label is affixed. The smart label comprises a layer structure and a detector system, the layer structure comprising of at least a stack of a first, a second and a third layer. The first and third layers comprise a flexible, electrically conductive or semiconductive material and at least two electrodes for connecting the layers to the detector system. The second layer comprises a flexible, deformable and compressible material. The second layer is electrically nonconductive or electrically conductive but less conductive than the first and third layers, wherein the second layer separates the first and third layers. | 09-30-2010 |
| 20100220395 | FABRICATION PROCESS OF A MICROFABRICATED BLAZED GRATING - A blazed grating is disclosed as well as mode hop-free tunable lasers and a process for fabricating gratings of this type. The grating lies in a general plane and includes a plurality of elongate beams carrying mutually parallel respective reflection surfaces spaced apart from one another with a predefined pitch, each of these reflection surfaces having a normal direction inclined at a grating angle α to the normal direction of the general plane. The grating includes a plurality of resilient suspension arms connected to the beams and intended to be fastened to a grating support. A first pair of comb electrodes is provided for applying a mechanical force to this assembly, being placed on a first side of the grating, along an axis transverse to the beams, and designed so as to allow the pitch of the grating to be modified in response to the application of the mechanical force. | 09-02-2010 |
| 20100183459 | MINIPUMP - The present invention discloses an adhesion rotary disc pump comprising a housing embedding therein at least one adhesion-propelling disc mounted on a rotatable shaft that is drivable by a drive, wherein fluids engaging with said at least one adhesion-propelling disc are transportable from at least one inlet to at least one outlet. In embodiments, the pump employs a scraping unit operative to scrape off fluid adherent on both sides of each of the at least one rotatable adhesion-propelling disc and that the scraped-off fluid is being channeled directly or indirectly to the at least one outlet. | 07-22-2010 |
| 20100062480 | DEVICE, SYSTEM AND METHOD FOR STORING AND SORTING CELLULAR SAMPLES - The present invention discloses a sample sorter system adapted to receive and sort samples according to predetermined criteria. The sample sorter system comprises a receptacle that is adapted to receive and retain fluid and samples. The receptacle is operatively coupled with a drive and with a power source such that actuation of the drive causes the rotation of at least one circular component, which in turn causes the development of a flow regime in the receptacle such that the samples suspended in the fluid are conveyable along a closed path to at least one sample handling site that are positioned along said closed path. | 03-11-2010 |
