Title: Mark E Gramer: Innovator in Night Vision Technology
Introduction
Mark E Gramer is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of night vision technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Flux Monitor High Light Intensity Cut-Off Circuit for Night Vision Devices." This invention includes a photo detector and an integrator. Incident light striking the photo detector causes its resistance to change, resulting in a voltage change at the photo detector. As long as the photo detector voltage is below a first threshold voltage level, the integrator remains inoperative. When the voltage at the photo detector exceeds this threshold, it is applied to the input of the integrator, which then produces an output voltage proportional to the integral of the input current. Once the output voltage reaches a second threshold voltage, power to an image intensifier assembly within the night vision device is interrupted.
Another significant patent is the "Night Vision Scope with Improved Voltage Supply." This invention features an improved voltage supply that includes a battery generating a voltage, which is proportionally increased by a voltage step-up circuit. This provides the necessary voltage to an image intensifier and an infrared light source of the night vision scope. The voltage supply also includes circuitry for limiting the voltage output if a battery generates a voltage greater than required by the elements of the night vision scope.
