Abstract: A transparent display provides eye protection from lasers and other high intensity light sources. The transparent display allows users to view objects clearly through the display while also presenting text, graphics or video on the display surface. Simultaneously, the display assembly comprises a component that provides eye protection against high power radiation sources. The transparent display with eye protection provides both protection from high power light sources and an additional cockpit display surface for presentation of information including graphical images, symbology, video, text, and other data.

Abstract: A method and apparatus for diminishing display transients and jitter. The method and system disclosed utilizes prior illumination and position histories in displaying and illuminating representations, and elements comprising the representations, on the display. Recognizing repeated representations, finding their prior and current positions, and determining if the difference in position is over a threshold value, diminishes the jitter by displaying the representation in the new position if over the threshold value, or, if it is not over the threshold value, then displaying it in the prior location. The illumination of an element at an intensity, which is based on prior illuminations and/or intensities of the element, diminishes the transients by avoiding flashing or flicker of transient illuminations.

Abstract: An automatic gain control system which measures the noise content of a received video signal and adjusts the gain of a radio frequency amplifier and a tuner to compensate for variations in noise levels. The apparatus uses a high frequency filter to strip the video information portion of a composite video signal to obtain only the noise component. The noise component is scaled and used in an automatic gain control feedback loop to control the gain of a radio frequency amplifier and a tuner. The system includes a standard AGC loop to regulate tuner gain for large amplitude signals to prevent overload.

Abstract: A microprocessor controlled phase locked loop tuning system is disclosed which comprises a microprocessor (10) that provides frequency data to the PLL (11), this data controlling a programmable frequency divider in the PLL to determine the nominal frequency of a VCO (131) in a tuner (13). The AFC detector (141) in the intermediate frequency module (14) provides an error voltage output to the AFC comparator (15). The comparator produces a low or a high output to the microprocessor depending on whether the error voltage exceeds a second input voltage to the comparator. This second input voltage is an increasing voltage from a time constant network (16) controlled by the microprocessor. The microprocessor program includes a loop wherein the microprocessor alternately increments a register and reads the output of the comparator until the voltage from the time constant network exceeds the error voltage from the AFC detector. The value in the register is then proportional to the error voltage.
