Title: Michael H Ranger: Innovator in Imaging and Signal Processing
Introduction
Michael H Ranger is a notable inventor based in San Jose, CA. He has made significant contributions to the fields of imaging and signal processing, holding a total of 7 patents. His innovative work has led to advancements that enhance the efficiency and quality of various technologies.
Latest Patents
Among his latest patents is a dry film development process for an aperture card printer. This invention eliminates line broadening in dry heat-developed films by utilizing a higher development temperature than the manufacturer-recommended standard. This approach allows for a much shorter development time while masking the edges of the film to prevent exposure. The combination of a hot/short development cycle and edge masking significantly reduces image smearing caused by emulsion shrinkage and migration.
Another notable patent is the low jitter phase-locked loop. In this invention, the jitter in the output signal of a phase-lock loop is minimized by driving a voltage-controlled oscillator (VCO) with the average voltage level across a capacitor. The voltage level is maintained by selectively pumping charge into the capacitor based on the deviation of the output signal from the desired output. This innovative design includes an error detector that receives an incoming digital signal and provides signals indicative of the difference between the incoming signal and a reference signal. The resulting output signal from the VCO is a function of the charge on the capacitor, enhancing the performance of the phase-locked loop.
