Abstract: Controlling displacement in a variable displacement compressor of an automobile air conditioning system entails detecting the temperature and humidity level of air entering the evaporator, setting a target air probe temperature from inside the automobile, and reading the evaporator air-out temperature at the temperature probe. From these parameters, the evaporator suction pressure can be calculated as can the load on the evaporator and the refrigerant flow rate so that the compressor swash plate angle, and thus, the compressor displacement, can be adjusted. After adjusting the compressor swash plate angle, calculating the absolute value of a difference between the actual air probe value and the vehicle occupant's air probe setting can be performed. If the absolute value is less than 0.5 degrees Fahrenheit, then the compressor stroke can be maintained, but if it is not, then the iteration must again be performed.

Abstract: An all-optical semiconductor waveguide optical regenerative device uses a nonlinear ridge waveguide structure to mix an input signal with a local oscillator signal to produce wavelength-switched and optically-regenerated signals. The ridge waveguide structure, and the local oscillator sources, filters and amplifiers may be tunable, microprocessor-controlled and monolithically integrated. The present invention relates to semiconductor waveguide-based structures, photonic application-specific integrated circuits, which can be used for optical signal processing and, more particularly wavelength-conversion, wavelength-shifting, wavelength-translation, wavelength-switching, wavelength-routing and optical signal transmission, amplification, pulse-shaping and regeneration in optical networks by integrating multiple functions on monolithic semiconductor substrates of Indium Phosphide and its ternary and quaternary semiconductor material derivatives.

Abstract: An insert for use in a chemical injector adapted to be interposed within the path of the fluid stream flowing from an upstream conduit to a downstream conduit. The insert has a body that includes a primary flow channel substantially parallel to the fluid flow. A chemical reservoir is formed on an outer surface of the tubular body and intermediate the upstream end and the downstream end of the body, with a chemical feed channel substantially parallel with the longitudinal axis and communicating with both of the reservoir and the downstream face. In an alternative embodiment, a chemical staging recession is structured on an outer aspect of the body. The staging recession forms a reservoir for fluid chemical when the insert is positioned within a chemical injector.

Abstract: An apparatus for introducing a chemical into a fluid stream comprises a chemical injector adapted to be interposed within the path of the fluid stream flowing from an upstream conduit to a downstream conduit. The chemical injector includes primary and secondary channels, substantially parallel to the fluid flow through the upstream conduit, and a chemical feed channel having an input end, adapted to communicate with a chemical source, and an output end coupled at an angle to the secondary channel. Injection of a chemical into a fluid stream comprises directing the stream through an upstream conduit; dividing the stream into a primary flow and a substantially parallel secondary flow; coupling a chemical source at an angle to the secondary flow; increasing the fluid flow pressure until chemical flow into the secondary flow is induced by vacuum pressure; and directing the primary and secondary flows into the downstream conduit.
