Owing to the poor performance of the previous CO2 two-rolling piston expander prototype, improvements were made to increase its efficiency.
In addition, it declares that any "invention, drawing, prototype, sketch, improvement, and innovation or study" completed during the term of the contract "will be considered the University's full property".
Moreover, restoration of cervical prototype and improvement of parametrial conditions were also considered as good responses.
The funding will go to bettering the engineering of the basic prototype, including improvements to GPS accuracy and improvement of overall durability (the Kafon is intended to survive multiple mine detonations, not just one), as well as mold-making and fabrication costs.
The results of an evaluation on this prototype showed improvements for both males and females, and also decreased gender differences in some outcome measures, such as confidence.
Nowadays, due to rapid prototyping processes improvements, a functional metal part can be built directly by Additive Manufacturing.
With state-of-the-art devices requiring about 0.3 2 W per device, our prototype shows an improvement of factor 10. Still, further improvements in terms of energy efficiency and bandwidth can be made.
Experiments conducted on the prototype verified the improvement in the force capacity and demonstrated a significant energy saving effect (20%37%%).
However, the prototype offered little improvement in performance over the N class when tested on non-restricted routes, which led to an initial reluctance within the management of the Southern Railway to authorise batch construction.
