Abstract: An analyzer and diagnostic system can include one or more sensors that are operable to generate combustion condition data relating to the performance of an associated combustion system. An analysis module can be operable to analyze at least a portion of the combustion condition data and determine a state of the associated combustion system. A diagnostic module can be operable to identify one or more recommended corrective actions for a combustion system performance deviation from a plurality of recommended corrective actions using one or more logic algorithms. Handheld instruments and methods of analyzing and diagnosing combustion processes are also included.

Abstract: A fluid line connector assembly includes a length of flexible tubing having a tubing end and a first fitting body received on the tubing end. A second is secured to the first fitting body, and at least one of the first fitting body and the second fitting body forms a fluid-tight connection with the tubing end. A third fitting body is rotatably supported on the second end fitting. A sealing member forms a fluid-tight seal between the second fitting body and the third fitting body. A method of assembling a fluid line connector assembly is also described.

Abstract: A hand-held programmer is provided for adjusting various functions of a multi-scene, multi-zone programmable lighting control. The programmer generally includes push-buttons for selecting particular scenes and zones to be programmed and for activating any one of the functions to be adjusted; namely, intensity, fade time, and fade delay. An alphanumeric LCD display includes a number of controllable display areas, adjacent to and aligned with the push-buttons, for identifying the names of the selected scene and zone and the function settings associated with them. A cylindrically elongated rotary encoder, having a knurled, rubbery surface, is easily manipulated to adjust the setting of the activated function and provides kinesthetic feedback, so that its adjustment can be coordinated with a visual perception of the lighting scene.
