Abstract: A solar power cleaning system is provided including a fluid supply line. A first end of the fluid supply line is utilized for receiving water. A second end of the fluid supply line is coupled to a plurality of nozzles for dispensing fluid onto solar panels. The cleaning system also includes a housing. Disposed within the housing is a valve for regulating soap from a storage compartment into the fluid supply line. The valve is controlled by a programmable controller. When the valve is open, soap mixes with water and is dispensed onto the solar panels via the nozzles. When the valve is closed, water may be dispensed onto the solar panels. A filter may be coupled to the fluid supply line to remove impurities from the water before dispensation onto the solar panels. A motor and pump may also be disposed within the housing to regulate the fluid pressure within the fluid supply line.

Abstract: A cleaning head for cleaning the slats in a window blind includes a manifold for receiving cleaning fluid, a plurality of spaced apart fingers arranged in a row on the manifold and at least one orifice defined in each finger for spraying the cleaning fluid onto the slats. Cleaning pads may be disposed on the fingers to contact the slats. The manifold may be divided to provide a source of vacuum to a second plurality of fingers with apertures defined therein for removal of excess cleaning fluid. Another embodiment of the cleaning head has couplings extending laterally from the fingers, and spacing elements may be interposed between the couplings to vary the spacing between adjacent fingers. Yet another embodiment of the cleaning head utilizes an enclosed compartment with slots defined in upper and lower surfaces for receiving a slat through the compartment.

Abstract: An educational and entertaining game apparatus is provided which teaches, tests, and rewards the players' knowledge of grammatical or language concepts and facts such as parts of speech, synonyms, vocabulary, sentence types, punctuation, and verb tenses, while simultaneously providing entertainment for the players. The players match an example of a grammatical or language category with a grammatical or language category selected by chance and accumulate matches to gain points.
