  • Publication number: 20220020125
    Abstract: A method of enhancing a portion of an aircraft digital video image in real time includes the steps of identifying a target area within a field of view of a camera, the target area including at least a portion of an aircraft structure and a shadowed region, and selecting for enhancement a predetermined pixel subset corresponding to the target area. The method further includes capturing an image using the camera, the image represented by a signal, providing the signal to a video processing box, formatting the image within the video processing box, and applying, using a processing device, a contrast enhancement algorithm to the predetermined pixel subset to create and enhanced image.

  • Patent number: 6759969
    Abstract: A fiberoptic transceiver system for use in an industrial paint spraying apparatus where analog information from flow sensors in the flow meter on the spray head is converted to a single channel digital signal for transmission on a fiberoptic cable to a receiver for decoding into an analog signal representing flow rate and a signal indicating flow direction. The encoding of two signals onto one channel is accomplished by encoding the flow rate as the frequency of the digital signal and the direction as the pulse width. The direction of the flow is determined by comparing the two analog signals from the flow meter and determining which signal is lagging the other.
