The left chart shows the adjusted detection distance compared to the actual sensing distance for white, gray, and black objects using a BGS sensor with a visible red light source. At an adjusted distance of 700mm, the measured sensing distance varies by ~150mm depending on what color is present. The right chart shows the same for a BGS sensor with an infrared source. This results in a sensing distance variation by color that can be just one third that of visible red versions, at the same distance.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
