L'invention de la semaine

Actualité oblige, un brevet que j'ai découvert grâce au site IPWatchdog.

Invention d'actualité, puisque l'inventeur du brevet US5255452, ayant pour titre "Méthode et moyens pour créer une illusion d'anti-gravité", s'appelle Michael J. Jackson.

Quelques extraits :

"Music entertainers and dancers are constantly searching for new and interesting elements which can be incorporated into their musical and dance performances. Interesting stage design, lighting, fog generators, laser light shows, and large video screens all enhance the appealability of live and recorded performances. Many popular music and dance entertainers expend great efforts in enhancing and choreographing their performances and dancing.

In the past, a professional entertainer, one of the inventors herein, has incorporated dance steps in his recorded video performances, wherein he and other dancers would lean forward beyond their center of gravity, thereby creating an impressive visual effect. This effect was accomplished by the use of cables connecting a harness around the dancer's waist with hooks on a stage, thereby allowing the dancer to lean forward at the required degree. However, since this requires stagehands to connect and then disconnect the cables, it has not been possible to use this system in live performances. Moreover, the cables obviously restricted arm and body movements."

Le brevet devait expirer en 2012, mais d'après le site de l'USPTO, il est déjà déchu.
