PI Awarded HyperBit Patent
PI (Physik Instrumente) LP, an Auburn, Mass., manufacturer of nanopositioning and precision motion-control equipment for photonics, semiconductor and life-science applications, has received a US patent for HyperBit, technology to increase resolution in existing D/A converters without additional hardware. PI said the technology enables it to provide higher resolution piezo-driven nanopositioning devices less expensively, and that it works equally well in open- and closed-loop situations. In closed-loop systems, it can exist upstream or downstream from the servo, the company said, and it can reduce higher-order granularity-driven artifacts. (US patent 6,950,050, "Method and apparatus for increasing effective resolution of analog output of digital-to-analog converter [DAC] having predetermined digital word size, where DAC drives plant.")
- The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
