An advanced digital optical inspection system is used on three insert injection-molding machines. These real-time inspection systems prevent improper loading of inserts and ensure that they are loaded. The systems feature three different types of optical sensors for specific applications. One uses fiber optics and infrared light, which filters out interference of ambient lighting; another is a laser-detection system which can focus a split-second light beam on a part less than 0.25 mm in diameter; the third system employs compact digital cameras with built-in processors.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
