Title: Method for reducing congestion in packet-switched networks
Inventor: CACERES RAMON
IPC: H04L12/14
Filed: 2000-03-14
Granted: 2006-10-10
Abstract: The present invention permits a network service provider to detect an operational condition - such as congestion - in a packet-switched network and to allevia te such congestion by providing customer incentives to avoid use of the network. The detection mechanism triggers an incentive such as the modification of the user's acces s charges and the customer can be immediately notified of either the occurrence of the congestion or of information regarding the incentive. Usage of the network during congested periods can be deterred by imposing additional access charges during such periods - similarly, customers can be given a discount to encourage usage during periods of low congestion. An incentive schedule can be tailored to dynamically change the usage patter ns of the customers of the network to accommodate the operational conditions in the network. The present invention has application in the Internet, where a detection/notification mechanism, for example, can be implemented in a network node such as a muter or in a network endpoint such as a client machine or a proxy or mail server.

Granted: 2003-09-02
Abstract: An electrochemical mirror includes a transparent first electrode (106) and a second electrode (110) distributed in localized areas. An electrolytic solution (112) is disposed between the first and second electrodes and contains ions (116) of a metal which can electrodeposit on the first and second electrodes. A negative electrical potential (118) applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodeposited from the solution onto the first electrode, thereby affecting the propagation of electromagnetic radiation through the mirror. A surface modification layer (108) applied to the first electrode ensures that the electrodeposit is substantially uniform, resulting in a mirror layer which increases the reflectivity of the mirror.  Conversely, a positive electrical potential (118) applied to the first electrode causes deposited metal to be dissolved from the first electrode and electrodeposited from the solution onto the second electrode, thereby increasing the transmissivity of the mirror.

Abstract: L'invention concerne des compositions nutritionnelles ou thérapeutiques servant à accroître les taux de corps cétonique dans le sang de mammifères par l'apport d'une source de corps cétoniques sous la forme d'oligomères linéaires ou cycliques et/ou de dérivés de 3-hydroxyacides. Le 3-hydroxyacide peut se présenter sous la forme d'un oligomère linéaire de 3-hydroxyacides autres que des homo-oligomères linéaires d'acide 3-hydroxybutyrique s'il est administré en combinaison avec un acétoacétate, des oligomères cycliques de 3-hydroxyacides, des esters des oligomères linéaires ou cycliques, des esters de 3-hydroxyacides autres que l'acide 3-hydroxybutyrique, et des combinaisons de ceux-ci. On appelle généralement oligomère un polymère composé de trois ou davantage d'hydroxyacides. Des 3-hydroxyacides préférés comprennent notamment un 3-hydroxybutyrate, un 3-hydroxyvalérate, un 3-hydroxyhexanoate et un 3-hydroxyheptanoate. Des oligomères de 3-hydroxyacides comportant un nombre impair de carbones tels que le 3-hydroxyvalérate présentent des avantages, puisqu'ils possèdent une teneur en énergie supérieure à celle d'oligomères de 3-hydroxyacides comportant un nombre pair de carbones. Les oligomères cycliques possèdent des propriétés avantageuses du fait qu'ils permettent d'obtenir un taux sanguin de cétone continu et/ou régulé sur une période de plusieurs heures. Les compositions peuvent être administrées par voie orale, par exemple, comme complément nutritionnel ou alimentaire, ou par voie intraveineuse. Une augmentation des taux de cétone dans le sang est utile en cas de troubles épileptiques, de maladies métaboliques, pour réduire le catabolisme de protéines, diminuer l'appétit, pour une nutrition parentérale, pour augmenter la fonction cardiaque, traiter des états diabétiques ou de résistance à l'insuline, ainsi que des conséquences de troubles neurodégénératifs et de l'épilepsie.
