Abstract: The invention relates to a locking device mounted directly on a circuit breaker and configured for mounting different locks. The locking device includes a yoke member, a slider member, a handle block and a lock. When the locking device is locked, the handle block abuts the operating handle in an engaged position corresponding to the operating handle in the ON or OFF position. Thus, the locking device locks the circuit breaker in the OFF position or the ON position. The locking device may further comprise a base member disposed between the yoke member and the housing. When it is desired to lock the circuit breaker in the on position, the base member is adapted to cover the push-to-trip button on the housing.

Abstract: A method of virtualizing reality, i.e., a method of creating virtual reality from images of a real event, is comprised of the steps of capturing a plurality of images of each time instant of a real event using a plurality of cameras positioned at a plurality of angles. Each image is stored as intensity and/or color information. A suitable internal representation is computed from these images and the information regarding the camera angles. An image of each time instant may be generated from any viewing angle using the internal representation of it. The virtual viewpoints could be displayed on a single TV screen or using a stereoscopic display device for a true three-dimensional effect. The event thus virtualized can be navigated through, and interacted with, any virtual reality system.
