Title: Innovations of John T Schmidt
Introduction
John T Schmidt is a notable inventor based in Amelia, OH (US). He holds a total of 12 patents that showcase his contributions to technology and engineering. His work primarily focuses on advancements in display technology and construction methods.
Latest Patents
One of his latest patents is for an active matrix organic light emitting diode (AM OLED) display. This invention presents an improved AM OLED pixel circuit and a method for wide dynamic range dimming. The technology ensures that color balance is maintained throughout the dimming range while preserving the uniformity of luminance and chromaticity at low gray levels. This innovation is particularly significant for avionics, cockpit, and hand-held military device display applications. The method utilizes Pulse Width Modulation (PWM) of the OLED pixel current to achieve the desired display luminance. Two example circuits are disclosed that modulate the common cathode voltage or common power supply voltage to control the OLED current. Additionally, three example circuits incorporate extra transistor switches in the pixel circuit to modulate the OLED current during the frame time. This combination allows for wide dynamic range dimming while maintaining essential display characteristics.
Another significant patent involves a post-tension cable protection system. This invention outlines a method for installing the system and remediating a defective post-tension reinforcement system. The method creates a waterproof seal for post-tension cable systems by roughening and decontaminating the cable's stressing end pocket with a diamond bladed reaming tool. The cavity is then sealed with epoxy resin and a precast plug made of non-shrink grout. This system ensures proper cable cutting, seating of the grease cap, and waterproof sealing at the cable's stressing end. Furthermore, it aids in removing previously grouted pockets when cable remediation is necessary.
