Abstract: The present invention is directed to 1,4-disubstituted piperidines, 1,4-disubstituted piperazines, 1,4-disubstituted diazepanes, and 1,3-disubstituted pyrrolidine compounds and their use.

Abstract: A method and system for creating Bounded Geographic Regions (“BGRs”) in a navigation system using BGRs is presented. Various methods for creating BGRs are disclosed. Additionally, the implications of minimizing the area of a BGR is discussed and disclosed. The method and system allows for easier convergence for creation of BGRs.

Abstract: An airway adapter comprising a tubular portion having opposing windows in a predetermined spaced configuration. The windows have at least one surface which interacts with moisture condensed thereon from respiratory gases so as to reduce the interference of such condensation with the measurement of constituent gases by a gas analyzer. The surface of the windows can be hydrophobic, hydrophilic, or a combination thereof.

Abstract: A CO.sub.2 monitor which has a reusable portion and a disposable portion is disclosed. The disposable portion includes an airway sensor for connecting between a ventilator output and an endotracheal tube. The airway sensor has ports on opposite sides. In one port a disposable infrared light source is inserted with wire contacts extending to the exterior of the airway sensor body. The reusable portion is a detector module which includes a detector and an amplifier. The detector module attaches to the airway sensor so that the detector is disposed in the second port and so that contacts in the detector module communicate with the wire contacts of the light source. The detector module may be removed from the airway sensor without removing the light source from the airway sensor.

Abstract: An agent gas analyzer that will determine the types and measure simultaneously the concentrations of a plurality of agent gases in a respiratory gas stream of an anesthetized patient, with the analyzer self-determining the agent gas types and concentrations each time gas measurements are made.

Abstract: A navigation system containing a software core, which uses bounded geographic regions (“BGRs”) and Node Pairs to explicitly optimize, in two dimensions, for user desired dependent variables, by analyzing variance due to standard and user-defined independent variables. The invention stores Node Pair data, and can use error function, feedback, and ANOVA/MANOVA to create a tightly convergent navigation solution.
