PI (Physik Instrumente), a manufacturer of nanopositioning and precision motion-control equipment for photonics, semiconductor and life science applications has received a United States patent (No 6,950,050) 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 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'.
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.
Typical Applications PI USA is seeking non-competitive licensees in many fields.
