The PHM is an atomic clock with outstanding stability for averaging times from 1 to 100, 000 seconds, to be used in precise positioning, time keeping and other on-boards applications. It is designed to perform in space environment for not less than 12 years. The operating principle exploits the stimulated energy emission occurring during the hyperfine transition of the atomic hydrogen in a miniaturised microwave cavity. The ultra stable RF [Radio Frequency] generated signal, at the frequency of 1420. 4057517.. MHz [megahertz], is used as a reference in a frequency synthesiser to generate the 10 MHz standard reference frequency. 3, record 3, English, - passive%20hydrogen%20mazer

GIOVE-B transporte à son bord deux horloges atomiques au rubidium et un maser à hydrogène passif [PHM], l'horloge atomique la plus précise au monde, toutes trois conçues et réalisées par la société neuchâteloise SpectraTime, filiale du groupe Orolia. Ces horloges constituent la base de temps des satellites, et donc l'élément clé de ce premier système de navigation européen. Elles permettent d'atteindre une stabilité de moins de 10 milliardièmes de secondes par jour. « C'est la première fois qu'un tel maser à hydrogène passif (PHM) est envoyé dans l'espace, et c'est lui qui donnera à Galileo ses performances uniques au monde. Pour donner un point de comparaison, nos horloges sont 10 millions de fois plus précises qu'une montre à quartz » [...] SpectraTime. 2, record 3, French, - maser%20%C3%A0%20hydrog%C3%A8ne%20passif

Ce satellite de test, baptisé GIOVE-B (Galileo In-Orbit Validation Element) [...] Galileo, premier système européen de navigation et de positionnement par satellite [...] sera compatible avec les deux autres systèmes de navigation par satellite couvrant l'ensemble du globe : le système américain GPS et le système russe Glonass. 2, record 3, French, - maser%20%C3%A0%20hydrog%C3%A8ne%20passif

Le maser ("Microwave Amplification by Stimulated Emission of Radiation") à hydrogène est une horloge atomique extrêmement stable basée sur l'atome d'hydrogène. Il a été inventé par Kleppner et Ramsey en 1960 à l'université de Harvard. Le principe de fonctionnement est semblable à celui du LASER sauf que la radiation émise est une radiation micro-onde et non pas optique. Le maser à hydrogène est utilisé principalement en radioastronomie et en géodésie comme horloge pour la synchronisation de radiotélescopes utilisant la technique du VLBI (Very Long Base Interferometry). Il est utilisé également pour la poursuite des sondes planétaires (Deep Space Tracking). Dans le futur, il pourrait être utilisé dans les systèmes de navigation par satellite de type GPS à cause de sa très grande stabilité (cf l'avenir du temps atomique ). 3, record 3, French, - maser%20%C3%A0%20hydrog%C3%A8ne%20passif

Standard Branching. Truly general-purpose industrial robot systems must have some way of selecting or altering the programmed path and function based on changes in the environment around them. The name given to such a facility may vary, but the purpose is the same. The robot reaches some point and interrogates an input signal to determine whether it is electrically active, or the robot is interrupted by activation of another input signal. In either case, the robot path "branches" to a section of the path/function program; if no signal is present at this decision point, or no interrupt occurs, the robot continues in a normal path sequence. 1, record 7, English, - standard%20branching
