20090132217 | BODY DYNAMICS CALCULATION METHOD, BODY DYNAMICS MODEL AND MODEL DATA THEREOF, AND BODY-MODEL GENERATION METHOD - A forward/reverse mechanics calculation of an accurate model of a human body having bone geometrical data and muscle/cord/band data is carried out at high speed. When a new skeleton geometrical model is given, a mapping between the new skeleton geometrical model and a pre-defined normal body model representing a normal body is defined to automatically produce a new body model. A processing unit reads model data to be subjected to mechanics calculation, reads a produced force f of a wire/virtual link exerted on the body model, reads the angle, position and velocity of the current rigid body link, calculates the Jacobian J | 05-21-2009 |
20090295711 | MOTION CAPTURE SYSTEM AND METHOD FOR THREE-DIMENSIONAL RECONFIGURING OF CHARACTERISTIC POINT IN MOTION CAPTURE SYSTEM - In an optical motion capture system, it is possible to measure spatially high-dense data by increasing the number of measuring points. In the motion capture system using a mesh marker, intersections of lines for the mesh marker are called nodes and the lines connecting the nodes are called edges. The system includes a plurality of cameras for capturing a two-dimensional image of the mesh marker by imaging a subject having the mesh marker, a node/edge detecting section for detecting node/edge information on the mesh marker from the two-dimensional image captured by the respective cameras, and a three-dimensional reconstructing section for acquiring three-dimensional position information of the nodes by using the node/edge information detected from the plurality of two-dimensional images captured by different cameras. | 12-03-2009 |

20090161258 | STORAGE DEVICE AND ASSEMBLY METHOD FOR THE SAME - A storage device includes a storage medium; a rotating shaft; a head actuator pivotally supported about the rotating shaft; a head fixed at an end of the head actuator for reading/writing information from/to the storage medium; and a magnetic circuit having a magnetic member and a magnet connected thereto. The magnet has a magnetic characteristic corresponding to the inertia of the head actuator. The storage device further includes a coil fixed at the other end of the head actuator. The coil generates a driving force proportional to the inertia when an electric current is flown through the coil by interaction with the magnetic circuit. The driving force causes the head actuator to be driven to adjust the head to a target position on the storage medium. The magnetic member is configured as a single unit having a common dimension among a plurality of storage devices having different specifications. | 06-25-2009 |
20090161260 | STORAGE APPARATUS AND RETRACTION MECHANISM FOR HEAD ACTUATOR THEREOF - A retraction mechanism for a head actuator having a head at the end thereof includes a metal piece that is attached to a coil arm, a stopper, and a magnet. The metal piece is configured to be attracted to the stopper with a magnetic force exerted by the magnet to retract the head outside the outer periphery of a storage medium. The metal piece is attached in contact with a surface of the coil arm other than the one facing the stopper. | 06-25-2009 |
