  11. 11. DESIGN GOALS<br />
  12. 12. DESIGN GOALS<br />Acquisition cost under 40 000 pesos<br />Maintenance every 4 months <br />Equipment weight under 12 kg<br />Adaptable to user characteristics<br />Noise Emission under 30 db<br />Interpres intentions of movement and have a simple user interface<br />The frequencies generated by the system, must not come into resonance with the tissue or bone<br />
  13. 13. DESIGN GOALS<br />System temperature must be under 28 ° C<br />The diameter of the limb can´t be increased in more than 15 cm<br />Tested for periods longer than the intervals between revisions, under strict conditions of use<br />Operate under different conditions of temperature and humidity<br />Work at least 6 hours by continuous use<br />Adaptable to different working conditions as variable inclinations and different soil conditions<br />Have at least 3 freedom degrees<br />
  14. 14. DESIGN GOALS<br />Range of flexion of least 80 ° at the knee <br />Support users with weights up to 120 kg<br />Resolution of 1°<br />Compatible with other biomechanical ankle systems<br />The installation and removal by the patient must not take more than 10 minutes<br />Manufacture must take 20 days or less<br />
