Title: Innovations by John R Bertschy
Introduction
John R Bertschy is a notable inventor based in Boulder, Colorado. He has made significant contributions to the field of technology, particularly in the areas of ink jet printing and data storage systems. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
One of Bertschy's latest patents is an "Apparatus and method for instrumented radial translation of a read/write." This invention addresses the start-up process of a rotating disk file by controlling the movement of sliders that support the read/write heads. The method involves applying voltage to voice coil motors to move the sliders radially outward, sensing their position, and initiating the rotation of the disk drive motor once the sliders have moved a specified distance. This innovation effectively overcomes stiction forces at the slider-disk interface, ensuring no damage occurs to the read/write heads or disks.
Another significant patent is the "Method and apparatus for minimizing evaporation in an ink recirculation." This invention is particularly relevant for continuous flow ink jet printers, where over 95% of the ink in the reservoir is recirculated. Bertschy's apparatus achieves a low evaporation rate by maintaining the ink temperature near ambient levels and minimizing airflow through the reservoir. This allows for the replenishment of ink without the need for additional solvent, thus enhancing the efficiency of ink usage.
