  • Publication number: 20080076100
    Abstract: A portable medical simulation system and method employs an artificial patient with a built-in haptic interface device, with up to four carriages for engaging different diameter catheters. A catheter stabilizer between each carriage expands and contracts in an accordion fashion as the carriages move in relation to each other, preventing the catheter from bending and bowing. A contrast display visual effect derived from a particle emitter software tool simulates the release of radiopaque dye within a simulated vasculature system for display on a monitor. A computer software based system is used for generating haptic effects on the catheter through control signals passed to each of the carriage motors controlling translation movement of the catheter and magnetic particle brakes controlling rotational movement of the catheter.

  • Publication number: 20050278691
    Abstract: A visual effect creation system and method is software designed for creating, maintaining, and displaying real-time 3D visual effects. There are two parts to the software. The first part is the creation and maintenance tool and the second part is a real-time display module. The creation and maintenance tool contains the real-time display module which greatly aids the creation phase. The real-time display module is also designed to integrate the 3D visual effect created with the creation and maintenance tool into the platform of the final product. With the creation and maintenance tool the user can create individual and modular 3D visual effects, which can later be incorporated into other effects or used as a stand-alone 3D visual effect. The data structure for each 3D visual effect is based on a hierarchical node design (parent-child relationship) which allows for inheritance of specific attributes from the parent to the child.
