Abstract

Le principe du projet JAVA combine l’autonomie de la montre mécanique à la précision du Quartz. L’énergie mécanique stockée dans un barillet transforme cette énergie en électricité par un générateur dont la vitesse de rotation est contrôlée à l’aide d’un circuit intégré cadencé par un oscillateur à quartz. Ce concept original a été lancé il y a plus de 10 ans et mené jusqu’à la phase d’industrialisation. En avance sur son temps, le produit n’a pas été introduit sur les marchés. Profitant des évolutions technologiques, une nouvelle architecture de générateur a été développée, permettant d’introduire un mode de régulation plus efficace. Il s’agit de redéfinir avec les moyens d’aujourd’hui le fonctionnement des circuits d’alors, de valider le nouveau mode de régulation, et de caractériser la performance du système.

Common Era

Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar (and its predecessor, the Julian calendar), the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the original Anno Domini (AD) and Before Christ (BC) notations used for the same calendar era. The two notation systems are numerically equivalent: " CE" and "AD " each describe the current year; "400 BCE" and "400 BC" are the same year.

Tao

Tao or Dao (道) is the natural order of the universe, whose character one's intuition must discern to realize the potential for individual wisdom, as conceived in the context of East Asian philosophy, East Asian religions, or any other philosophy or religion that aligns to this principle. This seeing of life cannot be grasped as a concept. Rather, it is seen through actual living experience of one's everyday being. Its name, Tao or Dao , came from Chinese, where it signifies the way, path, route, road, or sometimes more loosely doctrine, principle, or holistic belief.

Marcel Duchamp

Henri-Robert-Marcel Duchamp (UKˈdjuːʃɒ̃, USdjuːˈʃɒ̃,_djuːˈʃɑːmp, maʁsɛl dyʃɑ̃; 28 July 1887 – 2 October 1968) was a French painter, sculptor, chess player, and writer whose work is associated with Cubism, Dada, and conceptual art. He is commonly regarded, along with Pablo Picasso and Henri Matisse, as one of the three artists who helped to define the revolutionary developments in the plastic arts in the opening decades of the 20th century, responsible for significant developments in painting and sculpture.
