Title: Innovations of Stephen L. Marcus
Introduction
Stephen L. Marcus is an accomplished inventor based in Tucson, Arizona. He has made significant contributions to the field of imaging technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is for a solid-state camera with separate vacuum and sieve chambers. This invention allows for a small, low-cost solid-state camera by placing the molecular sieve in a chamber separate from the vacuum chamber that houses the solid-state device (CCD). The sieve chamber connects to the vacuum chamber via a narrow tube and functions as a passive pump. Additionally, the sieve chamber features a removable cover for easy replacement after manufacture. Another notable patent is an apparatus with an off-axis light path for characterizing luminous intensity. This apparatus determines the luminous intensity distribution of automotive headlights using a curved mirror and a curved screen. A solid-state camera captures the headlight output pattern from the screen, requiring a compact black box for the system. The design allows for practical component positioning and utilizes a linear CCD array to achieve economies by rotating the test lamp or scanning the linear array over various angular positions.
