  • Patent number: 5943476
    Abstract: A system for determining position and orientation of a stationary or moving object projects beams of electromagnetic waves, such as light, onto the object. The beams make lines on the object. A camera senses reflections of the lines. The reflections are converted into pixel data which are used to determine the position and orientation of the object relative to a predetermined coordinate system. The system can also maneuver a robot end effector to the object's position and orientation by interactively viewing representations of the object's position and orientation, and the end effector on a computer screen.

  • Patent number: 5936541
    Abstract: A transaction system is disclosed wherein, when a transaction, document or thing needs to be authenticated, information associated with one or more of the parties involved is coded together to produce a joint code. This joint code is then utilized to code information relevant to the transaction, document or record, in order to produce a variable authentication number (VAN) at the initiation of the transaction. This VAN is thereafter associated with the transaction and is recorded on the document or thing, along with the original information that was coded. During subsequent stages of the transaction, only parties capable of reconstructing the joint code will be able to uncode the VAN properly in order to re-derive the information. The joint code serves to authenticate the parties, and the comparison of the re-derived information against the information recorded on the document serves to authenticate the accuracy of that information.

  • Patent number: 5935848
    Abstract: A container that may be closed all around is useful for deepfreezing suspensions of living cellular materials kept in elastic bags. The container has two plane-parallel thin-walled metallic plates (14, 16) secured in swivellingly interconnected frame halves (20, 22). When the frame halves (20, 22) are superimposed, the plates (14, 16) secured therein are arranged with parallel faces at a slight defined distance from each other and form an intermediate cavity (12) in which the bag is placed. When the container is closed, the plates (14, 16) press the bag arranged inside (12) the container and flatten it until it has a small defined thickness. A microporous layer (30) that considerably increases heat transfer to the coolant that surrounds the container is secured to the outer side of plates (14, 16) by an adhesive layer. Furthermore, since the homogeneously flattened bag has a high surface/volume ratio and is pressed until it has no folds or bulges, the cellular material may be quickly and controllably cooled.

  • Patent number: 5935940
    Abstract: Polyionic derivatives of cyclodextrins and methods for preparing these derivatives are provided in which a polyionic derivative of cyclodextrin is combined with a growth factor, preferably a heparin binding growth factor. These compositions are of low solubility and are applied directly to the location of a wound. By virtue of the low solubility, the compositions remain in place at the site of application and slowly release growth factor. In an alternative embodiment, the cyclodextrin derivatives are administered in the absence of growth factor and are used to absorb growth factor present in the body at the location of the wound in order to prevent overstimulation of the wound response.
