Abstract: A mobile positioning, supporting and transporting system has two upright generally circular, oblong, elliptical or polygonal support structures joined together with lateral support members to form a freestanding structure with a roughly circular geometry so that it may be tipped end-over-end or rolled to translate from place to place. Any objects attached to or suspended from the structure within the volume space between the support structures readily are moved to a different location or position as desired. Alternatively, the support structures are disassembled and segments thereof may be aligned adjacent one another to form a cargo bin or cart to hold remaining portions of the structure and accessories for storage or transport.

Abstract: A hand-operated blade sharpener providing engagements of a blade by an abrasive stone at pre-selected angles to the blade is disclosed.

Abstract: A system and method are disclosed for providing instant access to notices for any notice-triggering event which may occur on a specific construction project. More specifically, the present invention is essentially a system and method for managing problems and risks associated with a wide range of construction projects using a project-specific software, system, method and process, usually accompanied by “hard copy” printouts of the relevant notices, forms and letters and the specific contract provisions that require a specific notice to be given by the construction company. In one embodiment, a customized CD-ROM package of notice documents that fully comply with a particular contract is prepared, which software package is then utilized to bring up appropriate notice document on a computer screen, which notice document is then completed by a user by inserting relevant information in open fields of the draft notice document.

Abstract: An architecture for development and execution of a system for implementing business logic includes an engine providing management of the system and execution of the business logic. A single service-side interface connects the engine to service side plug-in modules, and a single resource side interface connects the engine with resource-side plug-in modules. The server-side and resource-side plug-in modules connect to users and resources, respectively. The single interfaces conform the plug-in module interfaces to one interface to communicate with the engine. The single interfaces employ a single command definition. Development code defining the business logic is written by a user and executed by the engine.

Abstract: A system, method and apparatus for rapid, large angle, high-precision steering of one or more beams of light, and in particular, laser beams, using one or more concave reflectors to provide narrow, essentially collimated output beams. The rapid, beam steering device amplifies the angular deflection provided by a small angle steering element by means of one or more concave reflecting surfaces while controlling the divergence of the output beam using a divergence control lens, to produce an essentially collimated output beam in a field of regard that subtends +/?45 degrees on one axis and +/?50 degrees on an orthogonal axis.
