Abstract: A recreational vehicle air or air conditioning assembly may include a modular enclosure, a refrigerant circuit, and a water line. The refrigerant circuit may be mounted within the modular enclosure. The refrigerant circuit may include an evaporator. The water line may be directed at the refrigerant circuit in fluid isolation from the evaporator to guide a cooling water flow across a portion of the refrigerant circuit apart from the evaporator within the modular enclosure.

Abstract: A recreational vehicle air conditioner (RVAC) includes a ceiling-mount indoor panel positioned over an opening in the ceiling of a recreational vehicle and a control box assembly including a first box portion and a second box portion. The first box portion is positioned above the ceiling-mount indoor panel and the second box portion is pivotally connected to the first box portion with a hinge, such that it is pivotable between a closed configuration and an open configuration. The ceiling-mount indoor panel defines a control box recess that at least partially receives the second box portion when in the open configuration and a blank plate covers the control box recess when the second box portion is in the closed configuration.

Abstract: An electronic sensor assembly for a recreational vehicle may include a wired electronic sensor and a sensor cover supporting the wired electronic sensor on an interior wall. The sensor cover may include a cover sidewall, a cover faceplate, and a sensor clip arm. The cover sidewall may be in selective engagement with the interior wall. The cover faceplate may extend from the cover sidewall. The cover faceplate may have an outer surface direct outward from the interior wall and an inner surface directed inward toward the interior wall. The sensor clip arm may extend inward from the inner surface. The sensor clip arm may hold the wired electronic sensor within an interior volume defined by the cover sidewall and the cover faceplate.

Abstract: Flight parameter data is real time sampled in successive sample frames and temporarily stored in memory for one or more sample frame intervals, the stored sample values are examined to detect extremes in parameter values with time, periodic ones of the temporarily stored sample frames are permanently stored in memory at fixed frame intervals notwithstanding the presence or absence of extreme values in the sample set data, sampled frames intermediate to the fixed frames are stored only in the presence of extreme sample values amoung selected ones of the sensed flight parameters.

Abstract: A communications interface exchanges serial bit signals between sources differentially, over redundant, two conductor, primary and secondary channels. The primary channel provides the communications link during normal operation, and is monitored to ensure differential operation. In response to primary channel failure, the secondary channel becomes the communications link.

Abstract: A flight data recording system includes a digital flight data recorder (DFDR) and a digital flight data acquisition unit (DFDAU) having a signal processor and nonvolatile memory for storing signals representative of a deterministic flight mode algorithm which defines a generic aircraft flight profile by preselected modes, each mode defining a flight profile operating station, the deterministic flight mode algorithm defining the nominal values of some number of sensed flight data parameters in terms of the sensed values of some number of the remaining other sensed flight parameters. At each such station, the signal processor comparing the actual sensed mandatory flight parameter value with the corresponding determined value to establish sensor accuracy.
