In operation as single-effect mode, the prototype is driven by solar energy, whereas in operation as a double effect mode, an external energy source may be used.
The prototype can be driven forwards and backwards, and frequencies of the two voltages for the driving and friction reduction need not to be the same.
The mechanical shutter with a stepping motor, whose prototype has been driven 650,000 times in the laboratory experiment (Fukuhara et al. 2011), has been operated 86,000 times on orbit without any mechanical trouble.
The prototype car has been driven (which is to say, it's driven itself) 140,000 miles, including around San Francisco and from San Francisco to Los Angeles, and having experienced it in action, there is only this to say: it rocks.
Thus, even if some mutations occur in laboratory prototype strains they are driven by genetic drift, and it is not credible that they could mask the statistically supported B-cell targeted fixation of mutations observed worldwide for clinical strains.
Google gave a taste by putting a blind man in a prototype and filming him being driven off to buy takeaway tacos.
In 2004, a prototype was publicly tested by being driven over by a tank; it survived intact.
The experimental tests were performed in a lab-scale adsorption chiller prototype specifically designed and realized to be driven by the low grade waste heat (80 90 °C) from the engine coolant loop of a truck.
— or if it had indeed been driven at all — Mr. Rimac would say only that the car's components were tested in a prototype on closed courses.
The power output of a (1800 μm × 2000 μm) prototype was measured as 0.1 μW when driven with a peak input acceleration of 1.0 g at its resonance frequency of 192.5 Hz.
