Abstract: The present disclosure relates to, inter alia, a topical fluid application apparatus comprising a solution of glucosamine or a pharmaceutically acceptable salt thereof; an article of manufacture that is damp or impregnated with a solution of glucosamine or a pharmaceutically acceptable salt thereof; a kit comprising the topical fluid application apparatus and/or the article of manufacture disclosed; and methods of using the topical fluid application apparatus, the article of manufacture, and/or the kit.

Abstract: A method for controlling an engine having a cylinder includes sensing cylinder pressure; comparing the cylinder pressure to a pressure threshold; and adjusting an engine control parameter when the cylinder pressure exceeds the pressure threshold. A system for controlling engine operation is also provided.

Abstract: The combination of an intake air supply system with an internal combustion engine having a charge air cooler, a cylinder charging air intake and an exhaust discharge is provided. The intake air supply system includes a Roots-type positive displacement blower having inlet and outlet means and an exhaust gas driven turbo-compressor connected in series with the blower. The intake air supply system further includes a bypass passage connecting the blower inlet and outlet and a valve in the bypass passage to control the flow of fluid through the bypass. The valve is operative to open and close the bypass passage in response to engine operating parameters and to modulate the flow area of the passage in response to the same engine operating parameters so as to infinitely vary the flow area between the open and closed positions of the valve.
