  • Publication number: 20120314017
    Abstract: An image display apparatus includes a display layer and an image separation layer. The image separation layer is adapted to separate a displayed image on the display layer into a first image for a left eye of an observer and into a second image for a right eye of an observer. This renders the image display apparatus autostereoscopic. In order to improve the appearance of the displayed image, the apparatus is adapted to activate the display layer and the image separation layer substantially only within a given two-dimensional silhouette and to remain substantially transparent outside of the silhouette. In other aspects, the apparatus may be adapted to dynamically adjust an observation angle between the first image and the second image by controlling the distance between the display layer and the image separation layer by an actuator. The apparatus may be mounted on a robotic unit.

  • Patent number: 8309518
    Abstract: Bioactive molecules are entrapped within a matrix for the controlled delivery of these compounds for therapeutic healing applications. The matrix may be formed of natural or synthetic compounds. The primary method of entrapment of the bioactive molecule is through precipitation of the bioactive molecule during gelation of the matrix, either in vitro or in vivo. The bioactive molecule may be modified to reduce its effective solubility in the matrix to retain it more effectively within the matrix, such as through the deglycosylation of members within the cystine knot growth factor superfamily and particularly within the TGF? superfamily. The matrix may be modified to include sites with binding affinity for different bioactive molecules, for example, for heparin binding.

  • Publication number: 20120130538
    Abstract: A method to control a robot device that includes at least one manipulator which is moveable in an operating space, at least one actuator which actuates the manipulator, a sensor arrangement having at least one position sensor to determine the actual position of the manipulator and a controller which controls the actuator. The manipulator moves along an actual trajectory by means of an external force provided by an operator. The actuator provides compensation forces onto the manipulator influencing the torques or forces exchanged between operator and manipulator. The controller includes a conservative force field module having a conservative force field. The controller provides control signals for the actuator which provides the compensation force based on the control signals. The control signals are based on the conservative force field and on the actual position of the manipulator.

  • Publication number: 20110233472
    Abstract: A method of producing a rigid catalytically active porous ceramic is disclosed. Catalyst particles comprising a catalytically active material or a precursor thereof are mixed with a chemical additive, a ceramic binder, a carrier liquid and, optionally, substantially inert carrier particles to obtain a slurry having a gel-or paste-like consistency. The slurry may be transported to a substrate, e.g., by printing, or to a reactor cavity by a suitable flow method. The slurry is then heated to substantially evaporate said carrier liquid to obtain a rigid, catalytically active porous ceramic in situ. A catalyst obtainable by such a method and the use of such a catalyst are also disclosed.

  • Patent number: 7854959
    Abstract: A simple and reproducible preparative method for the fabrication of surface-chemical gradients is described herein. Surface-chemical gradient films are prepared by using a liquid front in relative motion to the substrate (e.g. immersion by a linear-motion drive or the use of a spreading droplet) to gradually expose substrate samples to very dilute solutions of adsorbates. As demonstrated by XPS, the self-assembled monolayer gradients produced in this way display a high packing density. This method can be used in the preparation of other gradients of various chemical or biochemical functionalities in one or two dimensions. Such gradients can be used in a wide variety of applications in such diverse areas as cell motility studies, nanotribology research, and high-throughput screening.

  • Publication number: 20100309226
    Abstract: For retrieving information based on images, a first image is taken (S1) using a digital camera associated with a communication terminal (1). Query data related to the first image is transmitted (S3) via a communication network (2) to a remote recognition server (3). In the remote recognition server (3) a reference image is identified (S4) based on the query data. Subsequently, in the remote recognition server (3), a Homography is computed (S5) based on the reference image and the query data, the Homography mapping the reference image to the first image. Moreover, in the remote recognition server (3), a second image is selected (S6) and a projection image is computed (S7) of the second image using the Homography. By replacing a part of the first image with at least a part of the projection image, an augmented image is generated (S8, S10) and displayed (S11) at the communication terminal (1).
