Abstract: A pneumatic counterbalance spring (10) includes a hollow cylinder (15) defining a first internal chamber (20) divided into a compression compartment (50) and an extension compartment (55) by a piston (25) movably mounted in the chamber. The compression compartment (50) contains pressurized gas and a seal assembly (60) which is mounted on the piston (25) prevents the gas from escaping into the extension compartment (55). A piston rod is slidably mounted in the open end of the piston. The piston rod (30) includes a hollow portion defining a second internal chamber (125) which is fluidly connected to the compression compartment (50) by a flow passage (140). A gas permeably insert (150) may be positioned in the flow passage to provide restricted rate flow of gas through the flow passage.

Title: Interleaving methodology and apparatus for cdma
Inventor: CHHEDA ASHVIN
IPC: H04L1/06
Filed: 1999-10-08
Granted: 2011-09-20
Abstract: Disclosed is an encoder, interleaves and splitter design approach for increasing system capacity. This is accomplished in a dual path embodiment by splitting the data stream into two subsets where one subset contains even number position bits of the original set and the other subset comprises the remaining odd bits. Each of the subsets may then be interleaved in standard fashion. This approach ensures that consecutively occurring bits in the original set are never transmitted from the same antenna and can be used to maximize the distance (and accordingly the time of transmission) between alternately occurring bits . The thought process behind this embodiment of the invention may be used to design a single interleaves as practiced in the prior art to accomplish the equivalent end result. The design process may be modified to include any number of transmission paths. Additional improvement of capacity may be obtained where each subset is interleaved in a manner to maximize the time separation between transmission of data bits, originally occurring L bits apart, prior to splitting or interleaving, in each of L data paths.

Abstract: La présente invention concerne un procédé permettant de traiter les perturbations du rythme circadien. Ledit procédé consiste à administrer de la mélatonine, des agonistes de la mélatonine ou des composés qui stimulent la production de mélatonine endogène de manière que la durée des taux plasmatiques effectifs de mélatonine, d'agonistes de la mélatonine ou des composés qui stimulent la production de mélatonine endogène chevauche le début ou la fin de la production de mélatonine endogène survenant avant le traitement, ce qui permet de provoquer un raccourcissement ou un prolongement des phases du rythme circadien, respectivement. Les procédés de la présente invention permettent de concentrer et/ou de prolonger les taux plasmatiques effectifs de mélatonine, d'agonistes de la mélatonine ou de composés qui stimulent la production de mélatonine endogène de manière qu'ils soient plus élevés dans l'intervalle de temps compris entre environ 8 heures avant le début de la production de mélatonine endogène crépusculaire et environ 4 heures après le début de la production de mélatonine endogène crépusculaire que dans l'intervalle compris entre environ 4 heures après le début de la production de mélatonine endogène crépusculaire et environ 8 heures avant le début de la production de mélatonine endogène crépusculaire, ce qui permet de provoquer un raccourcissement des phases du rythme circadien. Les procédés de la présente invention permettent également de concentrer et/ou de prolonger les taux plasmatiques effectifs de mélatonine, d'agonistes de la mélatonine ou de composés qui stimulent la production de mélatonine endogène de manière qu'ils soient plus élevés dans l'intervalle de temps compris entre environ 4 heures après le début de la production de mélatonine endogène crépusculaire et environ 8 heures avant le début de la production de mélatonine endogène crépusculaire que dans l'intervalle compris entre environ 8 heures avant le début de la production de mélatonine endogène crépusculaire et environ 4 heures après le début de la production de mélatonine endogène crépusculaire, ce qui permet de provoquer un prolongement des phases du rythme circadien. En outre, la présente invention concerne des procédés qui permettent de réguler l'exposition humaine à la lumière et à l'obscurité afin d'empêcher ou de favoriser, respectivement, la production humaine de mélatonine endogène. L'invention se rapporte également à l'utilisation d'antagonistes de la mélatonine, d'agonistes inverses et de composés inhibiteurs de la mélatonine tels que des bêtabloquants dans le but d'obtenir un effet de décalage du rythme circadien (opposé à celui obtenu par administration de mélatonine). L'invention se rapporte enfin aux modes d'emploi de ces procédés afin de soulager toute une gamme de troubles associés au rythme circadien, y compris les dyschronismes et perturbations des phases du sommeil associés au décalage horaire, aux dépressions hivernales et au travail en horaires alternants.
