Auburn, MA, - September 2006 - PI (Physik Instrumente) L.P., a leading manufacturer of nanopositioning and precision motion-control equipment for photonics, semiconductor and life science applications has received a United States patent for its development of an innovative means of increasing resolution in existing D/A converters, without additional hardware. This technology enables PI to provide higher resolution piezo-driven nanopositioning devices at a lower cost. The new technology will be marketed under the trade name "HyperBit™".
For more information, see U.S. Patent No. 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."
Licensees Wanted
HyperBit™ is a fundamentally flexible technology which can benefit virtually any application where the DAC update rate exceeds the responsiveness of the rest of the system. It works equally well in open- and closed-loop situations. In closed-loop systems it can exist upstream or downstream from the servo. HyperBit™ can also reduce higher-order granularity-driven artifacts.
