Title: Innovations by David M McVay
Introduction
David M McVay is a notable inventor based in Rochester, NY (US). He has made significant contributions to the field of printing technology, holding a total of 6 patents. His work primarily focuses on enhancing the performance and efficiency of LED printheads and gray scale printers.
Latest Patents
Among his latest patents is the "Data-dependent thermal compensation for an LED printhead." This invention provides an apparatus for estimating the junction temperature of an LED printhead based on an input data stream. It automatically compensates the printhead drive signal to maintain proper printer calibration, ensuring efficiency loss is minimized as the LED warms due to thermal energy generation. The invention utilizes a model of the thermal characteristics of the LED and its heat sink, producing an estimate of the LED temperature as a function of the image data.
Another significant patent is the "Hybrid digital image printer with halftone gray scale capability." This gray scale printer modulates an exposure source in both amplitude and duration according to an eight-bit data signal. The printer effectively controls the amplitude of the exposure source using the six least significant bits and the duration using the two most significant bits of the data signal. This innovative approach allows for enhanced printing quality and versatility.
