Abstract: Apparatus and associated methods relate to determining metrics of a cloud atmosphere using time difference measurements. A light projector projects a pulse of light into a cloud atmosphere, and a light sensor detects a portion of the projected pulse of light backscattered by the cloud atmosphere. A backscatter coefficient is calculated based on peak amplitude of the detected portion. An optical extinction coefficient is calculated based on a time difference between a peak time and a post-peak time, which correspond to times at which the peak amplitude of the detected portion occurs and at which the detected portion equals or crosses a sub-peak threshold, respectively. In some embodiments, a logarithm amplifier is used to facilitate processing of signals of widely varying amplitudes. In some embodiments, the sub-peak threshold is calculated as a fraction of the peak amplitude of the detected portion.

Abstract: A multi-fiber optical sensor system includes a light source configured to generate light energy, a transmitter fiber configured to receive the light energy from the light source and to project light energy out of a projecting end of the transmitter fiber over a transmitter fiber field of view, and a plurality of receiver fibers. Each of the plurality of receiver fibers has a receiving end aligned proximate and substantially parallel to the projecting end of the transmitter fiber and is configured to receive a received portion of the projected light energy reflected from a target within a receiver field of view. The multi-fiber optical sensor system also includes a lenslet array configured to shape the transmitter fiber field of view and give the transmitter field of view a finite cross-sectional area. The lenslet array has a plurality of lens corresponding to the transmitter fiber and each of the plurality of receiver fibers and is further configured to shape the receiver fiber field of view, tilt the center of the field of view with respect to the axis of the projected light energy for each of the plurality of receiver fibers and give the receiver fiber field of view for each of the plurality of receiver fibers a finite cross-sectional area. The multi-fiber optical sensor system also includes a detector configured to detect the portion of the projected light energy received by each of the plurality of receiver fibers. The receiver fiber field of view for each of the plurality of receiver fibers crosses the transmitter fiber field of view between a first crossing point at a distance Rmin from a lens axis and a last crossing point at a distance Rmax from the lens axis. There is a center crossing point Rmid at a point where a centerline of the receiver fiber field of view for each of the plurality of receiver fibers crosses a centerline of the transmitter fiber field of view. The range between Rmin and Rmax for each of the plurality of receiver fibers defines a detection zone such that each of the plurality of receiver fibers has a unique detection zone. Targets include a hard target and/or constituents of a cloud atmosphere.

Abstract: A fluid valve comprises a valve housing having at least one fluid inlet and at least one fluid outlet and having a valve axis. At least one of the inlet and outlet is arranged in a wall extending circumferentially about the valve axis. The valve further comprises a rotary valve body arranged within the valve housing for rotation about the valve axis. The rotary valve body comprises a frusto-conical valve body wall and at least one inlet or outlet valve body opening through the valve body wall, the valve body being rotatable about the valve axis so as selectively to place the valve housing inlet and valve housing outlet into fluid communication via the at least one valve body opening. The at least one inlet or outlet valve body opening is a slot which extends in the direction of the valve axis.

Abstract: A camera with a field of view toward an external environment of an aircraft is disposed within an aircraft door such that a ground surface is within the field of view of the camera during taxiing of the aircraft. A display device is disposed within an interior of the aircraft. A processor is operatively coupled to the camera and to the display device. The processor analyzes image data captured by the camera for docking guidance by identifying, within the captured image data, a region on the ground surface corresponding to an alignment fiducial indicating a parking location for the aircraft, determining, based on the region of the captured image data corresponding to the alignment fiducial indicating the parking location, a relative location of the aircraft with respect to the alignment fiducial, and outputting an indication of the relative location of the aircraft to the alignment fiducial.

Abstract: A camera with a field of view toward an external environment of an aircraft is disposed within an aircraft door such that a leading edge of a wing of the aircraft is within the field of view of the camera. A display device is disposed within an interior of the aircraft. A processor is operatively coupled to the camera and to the display device. The processor analyzes image data captured by the camera to predict a likelihood of foreign object collision with the leading edge of the wing, or detect damage or deformation to the leading edge.
