Patent CA-2645848-A1 (CA)
Title: Pneumatic launcher
Inventor: RUSSELL GILES
IPC: F42D3/00
Filed: 2008-12-04
Abstract: A pneumatic launcher includes a number of chambers for holding a compressed gas and a valve for releasing the compressed gas into a firing chamber to fire a projectile. The firing valve may include a number of surfaces on which pressure acts to slide a sliding valve body between an open position and a closed position.  The launcher may include a recess for preventing pressure from acting on one of those surfaces when the valve is in the closed position. A part of the sliding valve body may interact with adjacent parts to form a closed region ahead of the sliding valve body, in order to cushion motion of the sliding valve body. The launcher may have a breech and a breech pin shaped to create a desired gas flow within the firing chamber during firing. The breech may include a breech pin seal which seals between two faces oriented transverse to the axis of the launcher. The launcher barrel may have a number of ribs for improved stability and accuracy.

Abstract: A method for rendering and generating computer-generated video holograms from three-dimensional image data with depth information in real-time, wherein the position of the viewer (V) and the viewer's line of sight determines a view of a scene (3D-S), and at least one virtual viewing window (VW) in a viewing plane (VP) near the eye is assigned to the viewer, including the following procedural steps. Step 1): Three-dimensional rendering and generation of the depth map from scene section data from two parallel section planes that are perpendicular to the line of sight of the observer. Step 2): Transformation of the scene section data, wherein the dispersion of the light waves in the viewing window is propagated. Step 3): Repetition of the 3D-rendering and transformation steps with successive shifts of the section planes into the line of sight, wherein the results of the individual transformations are added up. Step 4): Inverse transformation, wherein the added data from the viewing plane are transformed into hologram data in the hologram plane.

Abstract: This invention is directed to a modularized interface for connecting a plug-in electric vehicle to the energy grid. For use with public or semi-public outlets, the modularized interface comprises a module and a smart socket, where the module is integrated within or capable of being connected to, the vehicle's charging interface. The module is normally disabled, but is enabled only after the end user is authenticated, the smart socket and its associated meter have been identified, and the module and the end user's account with the local utility are validated. The module meters the energy consumption, and, when the module is disconnected from the smart socket, indicating termination of the charging session, the metered data is communicated to the utility for updating the end user's account, and the module is disabled. The module is also capable of use with conventional outlets located, for example, in private residences.
