  • Patent number: 9208612
    Abstract: Methods of generating a three dimensional representation of an object in a reference plane from a depth map including distances from a reference point to pixels in an image of the object taken from a reference point. Weights are assigned to respective voxels in a three dimensional grid along rays extending from the reference point through the pixels in the image based on the distances in the depth map from the reference point to the respective pixels, and a height map including an array of height values in the reference plane is formed based on the assigned weights. An n-layer height map may be constructed by generating a probabilistic occupancy grid for the voxels and forming an n-dimensional height map comprising an array of layer height values in the reference plane based on the probabilistic occupancy grid.

  • Patent number: 9088791
    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: 8854178
    Abstract: Shaking patterns and/or environmental information associated with real-world handheld devices may form a basis for enabling authentication and/or effectuating events in a virtual environment. The handheld devices may include toys and/or other object that can be used to play. The handheld devices may be associated with the virtual environment in that individual handheld devices may share an appearance and/or theme with an avatar, a virtual object, and/or other element within the virtual environment. Shaking a pair of handheld devices together may facilitate authentication of the handheld devices with respect to the virtual environment and/or effectuate one or more events within the virtual environment. By way of non-limiting example, two avatars may dance together or become friends in the virtual environment responsive to two corresponding handheld devices being shaken together.

  • Patent number: 8784949
    Abstract: The present invention relates to a novel process for the remote plasma surface treatment of substrate particles at atmospheric pressure. The invention is motivated by the urge to overcome major drawbacks of particle treatment in low pressure plasmas and in-situ particle treatment at atmospheric pressure. The former requires complex and mostly expensive vacuum installations and vacuum locks usually prohibiting continuous processing. Independent of the system pressure, in-situ plasma treatment causes particle charging and therefore undesirable interaction with the electric field of the discharge, which is seen to contribute to the process of reactor clogging. Additionally, the filamentary discharges modes of atmospheric pressure plasmas are inflicted with inhomogeneous surface treatment. Furthermore, short radical lifetimes at elevated pressures complicate a remote plasma treatment approach as widely used in low pressure applications.

  • Publication number: 20140133745
    Abstract: A learning unit 4 generates a function table indicating the relationship between the class number and position information of an object and the probability of appearance of the object for each small area image pattern of a code book, calculates a sharing matrix indicating the commonality of a feature amount between the classes, makes a tree diagram in which the classes with a similar feature amount are clustered, and calculates the weight of each node in the tree diagram for each small area image pattern. The recognition processing unit 7 compares image data captured by a camera 2 with the code book, selects the closest small area image pattern among a plurality of small area image patterns, extracts the class related to the node with the smallest weight among the nodes with a weight equal to or greater than a threshold value for the selected small area image pattern, and votes the position information of the small area image pattern for the class, thereby recognizing the object.
