Abstract: L'invention concerne un dispositif de condensation d'oxygène de type adsorption de variation de pression équipé d'au moins un tube d'adsorption qui est construit à partir d'un élément creux ayant un premier et un second orifices et qui est rempli d'un agent d'adsorption qui adsorbe sélectivement de l'azote et non de l'oxygène, d'un moyen d'alimentation en air sous pression relié au premier orifice du tube d'adsorption et alimentant ce dernier, un moyen d'évacuation des gaz relié au premier orifice du tube d'adsorption et permettant d'évacuer un gaz de ce tube, et un moyen de commutation mettant en communication les moyens d'alimentation en air sous pression et d'évacuation des gaz avec le premier orifice. Pour produire un gaz de condensation d'oxygène, le dispositif de condensation répète une étape d'adsorption et une étape de récupération. Lors de l'étape d'adsorption, le moyen d'alimentation en air sous pression fournit de l'air sous pression au tube d'adsorption, l'azote étant adsorbé à partir de l'air. Lors de l'étape de récupération, la pression dans le tube d'adsorption est réduite afin de séparer l'azote adsorbé par l'agent d'adsorption à partir du tube d'adsorption, ce qui permet de récupérer l'agent d'adsorption. La pression du gaz de condensation d'oxygène est régulée par des cycles de régulation des étapes d'adsorption et de récupération du moyen de condensation d'oxygène.

Title: Method and apparatus for raman crosstalk reduction via idle data pattern control
Inventor: EFFENBERGER FRANK J
IPC: H04B10/04
Filed: 2005-12-22
Granted: 2012-04-03
Abstract: Methods and apparatus are provided for reducing Raman crosstalk in a wavelength-division-multiplexing (WDM) optical fiber transmission system (10) that transmits a multiplex of channels. Idle data is sent over one or more of the channels of the WDM system in order to maintain the optical link (30) when user data is not being sent. The idle data has an idle data pattern, which can be controlled such that a power spectral density of a signal carried by at least one channel is shifted in order to reduce Raman crosstalk between the channels. For example, the power spectral density may be shifted away from lower frequencies of the channel, and toward the higher frequencies, by controlling the idle data pattern. Alternatively, the power spectral density may be shifted towards unused frequencies of the channel, by controlling the idle data pattern.
