  • Patent number: 10789729
    Abstract: A system and method for determining a projectile impact location is described. Embodiments of the projectile impact location system can include, but is not limited to, a control module, a camera with removable filter, a projector, and a light source. The projectile impact location system can be implemented to determine a location of a projectile impact and generate coordinates of the impact location for use by an animation engine.
    Type: Grant

  • Patent number: 9068996
    Abstract: Disclosed is a method of determining the presence of an analyte of interest by means of a detection of a reaction product between the analyte of interest and a reactant, the method comprising extracting the analyte of interest from a complex sample matrix; transferring the analyte of interest to an initial reaction mixture; performing a background measurement on the initial reaction mixture comprising at most a negligible concentration of the reaction product, wherein the reaction conditions present in said initial reaction mixture at least reduce the reaction rate of the formation of the reaction product such that the background measurement can be performed without a measurable change in said negligible concentration; altering the reaction conditions in the initial reaction mixture to accelerate said reaction rate; continuing said reaction until the concentration of the reaction product has stabilized; performing a second measurement on the resultant reaction mixture to obtain a signal correlated to said con

  • Patent number: 6951278
    Abstract: Apparatus used for holding a disc (12) including a lower surface and an upper surface with an opening extending between the surfaces, comprises a base (1) and a hub (2) extending upwards from the base. The hub includes a center portion (6) adapted to pass through the opening of the disc and engage the upper surface of the disc (12) to hold the disc on the hub. The hub (2) includes outer pieces (4), non-movable with respect to the base (1), for arresting downward movement of the disc (12) during its removal.
