I've seen functional prototypes of both technologies.
Prototypes of both HPDs are being built in a dedicated vacuum deposition facility at CERN.
Prototypes of both these detectors have been successfully tested and operated.
The prototypes of both portal and worksheet were improved across the design experiments, and their success rates increased.
A global competition that offered a cash prize would encourage prototypes of both to be brought to market and the competition could help to drive down the production cost of the winning entry.
Experimental prototypes of both the American and German designs were built and operated from the 1960s to the 1980s, but by the early 1990s, they had resulted in no orders for commercial plants.
A complete development environment for the rapid prototyping of both the hardware and software components of digitally based control systems for electromechanical applications is here proposed.
The system allows cost effective, rapid prototyping of both microelectrode designs and microfluidic systems using standard microfabrication techniques, available to most research groups.
Prototypes of both devices have been constructed and exposed to sets of well-characterized reference fields: the resulting measured responses are presented and discussed here, compared against comprehensive Monte Carlo data.
