    Abstract: An apparatus for displaying collimated images including an ellipsoidal mirror having a focal surface and means for generating a bar and scale image for the mirror in the focal surface. The means generating a scale image includes an elongated strip of film or tape containing indicia which is positioned intermediate an elongated light source and the mirror to display a scale image on the mirror, and the means generating the bar image includes a transverse bar which reflectively defines a bar image on the mirror intersecting the scale image. The generating means includes means for moving the tape strip to modify the scale image and means for moving the bar to displace the bar image on the mirror and modify the position of intersection between the bar and scale images.

    Abstract: An analog position transducer connected to an aircraft flap generates a linear voltage representing flap position. Separate switching stages are responsive to different potential levels of the linear voltage to produce separate output waveforms which are summed by an operational amplifier for each reference program which is to be generated. The disclosed reference programs correlate desired angle of attack to flap position for an aircraft approach program and a climbout program.

    Abstract: An AC power supply powers several transducer circuits, in which input voltage variations cause variations in the output signals from the transducer circuits. A time division multiplier has an input connected to the AC power supply and a second input connected to a fixed DC voltage source. Variation in AC amplitude change the duty cycle of pulses generated by the multiplier. Semiconductor detector gates are driven by the multiplier pulses in order to demodulate and divide the output signals of the transducer circuits by a factor proportional to the duty cycle, thereby compensating for variations from the AC power supply.

    Abstract: An independent test sight is described for a pilot's head-up display (HUD). In one embodiment, the independent test site comprises a collimator assembly and an aligned periscope assembly. The collimator assembly comprises a source of light, a reticle, and a lens for projecting the image of the reticle. The periscope assembly comprises a rhomboid prism housed within the chassis of the HUD in such a manner that it can be pivoted from a stowed position to an erect position where it projects a reticle pattern in the field of view of the HUD combiner.

    Abstract: An on-axis, optical head-up display device, for use in fixed installations, vehicles or aircraft, utilizes a single block of transparent acrylic with the upper surface curved end coated to form a collimating mirror. The block itself is comprised of two major portions cemented together with a transparent bonding material wherein the resulting interface forms a combining surface. A generated image is transmitted from the focal plane of the collimating mirror upwardly through the combining surface; then it is reflected downwardly by the collimating mirror back to the combining surface which in turn serves to combine the generated image with a background view. The combined image is viewed by an observer through a back window of the block. Optical aberrations are reduced by extending the material of the block to the focal plane of the collimating mirror where an image generator is located.
