Abstract: The solar canopy support system has at least two beam support columns. Each beam support column has a first end connected to a ground surface and extends substantially vertically along a longitudinal axis from the first end to a second end. There is also a zee channel support beam connected at the second end of each beam support column. The zee channel support beam includes a longitudinal axis within about 0 degrees to about 30 degrees of perpendicular to the longitudinal axis of each beam support column. There are also two or more zee channels. Each zee channel has a first end connected to an upper portion of one zee channel support beam and has a second end connected to an upper portion of another zee channel support beam. Each zee channel includes a longitudinal axis substantially perpendicular to the longitudinal axis of each zee channel support beam; at least one solar power array connected on an upper portion of at least two zee channels.

Abstract: A box opener that includes a shaft extending along a longitudinal dimension. The shaft supports a box broaching wedge, operatively supported by the end of the shaft. The wedge narrowing from a base that is at least 2 cm (0.79 in) in dimension transverse to the longitudinal dimension of the shaft to a blunt edge spaced from the base by at least 2 cm (0.79 in).

Abstract: A power delivery system is disclosed including a primary power bus for transferring power to the facility from on-site generators, and a secondary power bus for transferring power to the facility from a utility. The system further includes a static disconnect switch capable of quickly isolating the facility from the utility power grid, and a controller for controlling the overall operation of the power delivery system. In a normal mode of operation, the utility supplies power approximately in the amount of the single largest load in the facility, with the remaining power being supplied by the on-site generators. If one or more of the generators go off-line, the power supply from the utility may be increased. Similarly, if the quality of the power supplied by the utility drops below a predetermined level, the static disconnect switch quickly opens and islands the facility, whereupon 100% of the power is supplied by the generators.

Abstract: A rolled sheet material dispenser and holder that allows one to tear off a single sheet at a time without unrolling unwanted sheets. The apparatus is designed so that the moment of inertia of the core element and paper roll are sufficient to retard excessive spooling when a sheet is torn off the roll.
