Abstract: A stereoscopic 3D viewer used in conjunction with a portable computing device displaying a pair of stereoscopically complementary images. In an improved stereoscopic 3D viewer, the pair of stereoscopically complementary images enter the and right eyes of the user along substantially parallel paths, to eliminate or substantially reduce the need for the user to cross his or her eyes and to improve focus and sharpness of the images. In additional embodiments of the improved stereoscopic 3D viewer, baffles are provided to block the extraneous direct view of the pair of stereoscopically complementary images.

Abstract: A method and apparatus for operating and actuating remote devices using a single pair of wires together with communication and networking protocols necessary for operational control of the remote devices and data gathering activities from the remote devices. The invention leverages the use of existing wiring and is particularly useful in heating and air conditioning systems, sprinkler control systems, security systems, lighting control systems, industrial automation control systems and similar environments.

Abstract: Systems and methods are described to address the problem of maintaining only unique data values accessed through name-value tuple sets. A knowledgebase represents data in tuple sets where all the data across the tuples comprise unique instances for memory conservation and system performance purposes. The knowledgebase stores and maintains unique values in a data store structure and represents the values as tuples through the tuple store structure. Modules access tuples and their values through handles called tuple tickets. The knowledge base defines a set of valid data types that can be maintained, and all data types are accessible via a common interface. In addition, memory management is optimized using a system that frees objects that are no longer referenced.
