PI has received a US Patent for an innovative means of increasing resolution in existing D/A convertors without additional hardware.
PI has received a US Patent (No 6,950,050) for its development of an innovative means of increasing resolution in existing D/A convertors, 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 tradename HyperBit.
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 artefacts.
