Abstract: A leashed collar for a dog or pet having individual links that connect and form the structure of the collar. Links may be easily added or removed for length adjustability. The collar is structured for adding a martingale attachment in one embodiment. Other decorative and ornamental articles can be added to the collar, such as jewelry. The collar has a plurality of links, with each link comprising an upper horizontal member, and vertical legs. The vertical legs are spaced apart from each other and extend generally parallel to each other. A plurality of connectors has vertical voids extending there through. Vertical legs of the links extend through the vertical voids of the connectors. Lower horizontal members engage a vertical leg of the links to hold the construct together.

Abstract: A computer-based system, computer-implemented method, and computer program product facilitate determining energy cost savings in an energy-consuming facility, such as a commercial building, using an artificial intelligence model, for example a neural network model, that projects or estimates the amount of energy that would have been consumed by the facility but for the implementation of energy efficiency or conservation measures. Energy savings are represented by the difference between the estimate of energy that would have been consumed but for the measures and the actual amount of energy consumed by the facility under actual conditions during a time interval after the measures have been implemented.

Abstract: A fluorescent lighting system capable of providing three levels of illumination includes a first circuit in which a line voltage supply is connected to an electronic ballast which drives four fluorescent lamps. Each fluorescent lamp serves as the center lamp in one of four three-lamp parabolic fixtures. A second circuit is comprised of a second line voltage source connected in parallel with two similar electronic ballasts which drive the side fluorescent lamps in the three-lamp parabolic fixtures. When the first circuit is powered, the center lamps in all parabolic fixtures are illuminated to provide a first level of illumination. When the second circuit is powered, the side lamps in all parabolic fixtures are illuminated to provide a second level of illumination. A third level of illumination is provided when both the first and second circuits are powered and all three lamps in all four parabolic fixtures are illuminated.
