Abstract: A compact handheld imaging apparatus (700) which can be used to capture high-quality iris images for identification of a person.  The handheld iris imager is non-invasive and non-contacting and comprises a camera (105), a cold mirror (120), a lens (110), and an illuminator (130). The imager has sensors and indicators (555, 556, 557, 560) which assist a user in aligning and focusing the device. The imager also automatically captures the image when proper positioning is achieved. A template of the image is then compared to a database of previously stored templates of images to identify the person. The imager is integrated into a telecommunications device as a security module. The telecommunications device cannot be unlocked and used unless a user has been identified and authorized by the imager.

Abstract: A touch roller 20 (a driven roller) is mounted on the free end 22a of a support arm 22 that can rotate. A changeover mechanism 26 rotates the support arm 22, thus changing the inclination of the support arm 22. The touch roller 20 is thereby moved between two positions. In the first position, the touch roller 20 is pressed onto a forward driving roller 12. In the second position, the touch roller 20 is pressed onto a reverse driving roller 14. The rollers 12 and 14 are spaced apart from each other. The touch roller 20 may be moved to the third position, where it remains spaced from both the forward driving roller 12 and the reverse driving roller 14. In the second position, the touch roller 20 can be pushed onto the reverse driving roller with a small force or a large force. When the touch roller 20 is pushed onto the reverse driving roller 14 with the small force, the reverse driving roller 14 pulls back a band 15.  When the touch roller 20 is pushed onto the reverse driving roller 14 with the large force, the reverse driving roller 14 tightens the band 15.

Granted: 2012-08-28
Abstract: Disclosed are a variety of methods for achieving enhanced expression from a target nucleotide sequence in a plant e.g. comprising the step of transiently introducing into a tissue of a plant (e.g. a leaf) a first nucleic acid comprising the target nucleotide sequence and a second nucleic acid encoding a Post Transcriptional Gene Silencing (PTGS) suppressor protein (preferably of viral or plant origin), wherein the first and second nucleic acids are comprised within a single binary vector, construct, or the first and second nucleic acid sequences are comprised within a first binary vector and a second binary vector construct respectively. The plant tissue may then be harvested for the protein. Such methods can give much higher levels of gene expression than are obtainable using stable transgenes, or certain replicating vectors.  Also disclosed are specific PTGS suppressor proteins: potato virus X (pvx), p25 protein; african cassava mosaic virus (acmv) AC2 protein; rice yellow mottle virus (rymv) P1 protein; tomato bushy stunt virus (tbsv) 19K protein;  plus variants of these. These suppressors may be used in any PTRS context, including the enhancement of transient expression systems.

Abstract: L'invention concerne un procédé de surveillance d'une liaison amont dans un système à débit binaire élevé. En l'occurence, une station de base émet vers un terminal d'accès uniquement via un canal de trafic aval dès que la station de base doit envoyer des données au terminal d'accès. Chaque terminal d'accès génère des mesures périodiques de débit binaire sur la base du signal de liaison aval reçu. Chaque terminal d'accès réduit alors la période durant laquelle il émet sur la liaison amont sans être commandé en puissance. Pour cela, il met hors fonction son émetteur sur la base des mesures de débit binaire.

Abstract: A system and method of developing better-designed medical devices, particularly prosthesis and more particularly cardiovascular stents and endovascular grafts. The system comprises a geometry generator, a mesh generator, a stress/strain/deformation analyzer, and, optionally, a visualization tool. In one embodiment, the geometry generator receives three-dimensional volumetric data of an anatomical feature and generates a geometric model. The mesh generator then receives such geometric model of an anatomical feature or an in vitro model and a geometric model of a candidate medical device. In another embodiment, the mesh generator only receives a geometric model of the candidate medical device. Using the geometric model(s) received, the mesh generator creates or generates a mesh or a finite element model. The stress/strain/deformation analyzer then receives the mesh, and the material models and loads of that mesh. Using analysis, preferably non-linear analysis, the stress/strain/deformation analyzer determines the predicted stresses, strains, and deformations on the candidate medical device. Such stresses, strains, and deformations may optionally be simulated visually using a visualization tool.

Abstract: The invention relates to a pallet container (10) comprising a thin-walled inner container (12), preferably consisting of a thermoplastic plastic, for storing and transporting liquid or free-flowing filling materials, a tubular framework of metal bars, which closely surrounds the plastic container (12) and acts as a support shell (14) and a base pallet (16), on which the plasti c container (12) rests and to which the support shell (14) is connected in a fixed manner. In order to receive official certification, the pallet contain er (10) must undergo various certification tests, such as a compression pressur e test, interior pressure test or a drop test. During the drop test, the vertical lattice bars (20) are often wrenched out of or shear away from thei r anchorage on the base pallet (16). According to the invention, to prevent su ch detrimental effects, the tubular bars (18, 20) of the support shell (14) are provided with specific features in the event of the container falling, said features allowing a plastic deformation of the support shell (14) at specifi c predeterminable points, whilst preventing the individual tubular bars (20) from shearing or being wrenched out of their anchorage. According to one embodiment of the invention, the features allowing the plastic deformation o f the supportshell take the form of a flexure point coupled with a reduced cross-section of the bars.
