Title: Innovations of John M Schneider
Introduction
John M Schneider is a notable inventor based in Spring Valley, OH (US). He has made significant contributions to the field of ink jet technology, holding a total of 4 patents. His work has been instrumental in enhancing the accuracy and efficiency of ink jet printing systems.
Latest Patents
One of his latest patents is the "Ink jet filament length and stimulation amplitude assessment system." This invention measures the length of an ink jet filament as a function of stimulation amplitude in an ink jet printing apparatus. It involves locating a narrow charging electrode near the drop break-off point of the ink jet filament, varying the stimulation amplitude to change the filament length, and measuring the charge imparted to the ink drops as the filament length is adjusted. The stimulation amplitude is automatically adjusted based on the measured charge.
Another significant patent is the "Bipolar ink jet method and apparatus." This invention presents an improved ink jet marking architecture that enhances ink droplet placement accuracy. The architecture combines a bipolar scanning arrangement with a drop interlace scheme. The preferred marking apparatus consists of an array of ink jet column generators that direct ink droplets through a charging region and then a deflection region. The droplets are charged either negatively or positively, depending on the desired droplet trajectory. This innovative approach reduces the charge required for the droplets and minimizes coulomb interactions, thereby increasing placement accuracy.
