Bionicwoman

Ai»6-year-old woman has been fitted withtheworld'sfirst"bionic" device that is capable of producing coordinated fine hand and arm movement.

The woman has suffered two strokes that have affected her control over her researcher at the University of California in Santa Barbara, sued the firm for compensation, claiming to have received just $200 for his work on the invention.

In January 200^, the Tokyo District Court calculated Nichia will have made $1.2 billion profit from the invention | by 2010 and awarded Nakamura the | $190 million he had asked for. But Nichia successfully appealed the case, and this January the Tokyo High Court found the firm was responsible for 95 per cent of the original invention. The courtforced a compromise that ended when Nakamura reluctantly accepted only $7.6 million. Now the company has revealed details of its case, at a press conference on 11 May.

Nichia argued that the original patents Nakamura worked on were virtually obsolete and are no longer used by Nichia or the four companies to which it licenses its blue-LED technology. It also argued that Nakamura did not work alone on the LED project, and was receiving a salaiy of $190,000 when he quit at age kS, as well as $150,000 from stock options.

Nichia said it equipped the lab Nakamura used and had sent him to Florida for training in metal organic chemical vapour deposition, a key production technology that makes gallium nitride blue LEDs possible -and which was recommended by an adviser to Nichia, not Nakamura. Nichia also said it bore all the risk in developing and commercialising the technology. John Boyd, Yokohama •

left ami. On 13 May neuro-rehabilitation experts at the University of Southampton in the UK inserted five implants into the limb, each measuring 1.7 centimetres by 2A millimetres. These receive power and stimulation commands from a radio-frequency coil fitted to her ami and connected to a control unit.

The implants are selectively placed to stimulate key nerves controlling both deep and superficial musdes, allowing the patient to extend her elbow and wrist and open her hand. The system is intended to re-educate weak and paralysed musdes by supporting, rather than replaang, voluntary movements.
