Title: Innovations by Steven D. Seigal
Introduction
Steven D. Seigal is an accomplished inventor based in Boulder, CO. He has made significant contributions to the field of electrophotographic technology. With a total of 2 patents, his work focuses on improving image quality control systems.
Latest Patents
One of his latest patents is titled "Dynamic reference for an image quality control system." This innovative system checks copy quality variables within the image area of an electrophotographic machine. During a test cycle, quality is assessed by producing sample test areas within the photoconductor image area typically used for making copies. Reflectance measurements are taken on these sample test areas and compared to a dynamically floating reference achieved from a cleaned portion of the photoconductor. The testing circuit is designed to ensure that the same reflectance voltage is generated whether the reflectivity-sensing device is viewing a sample test area or a cleaned reference area. This system checks for quality variables such as toner concentration, image voltage, and an abnormally low reflectance photoconductor, providing a partial check on its own fault-free condition during periods of inactivity.
Another notable patent by Seigal is the "Abnormally low reflectance photoconductor sensing system." Similar to his previous invention, this system also checks copy quality variables within the image area of an electrophotographic machine. It employs a comparable method of producing sample test areas and measuring reflectance. The system is balanced to generate the same reflectance voltage, ensuring accurate quality checks. It also monitors quality variables and contributes to maintaining the machine's operational integrity.
