Title: System and method for equalizing the delay time for transmission paths in a distributed antenna network
Inventor: HUFFMAN JACQUE
IPC: H04Q7/00
Filed: 1997-07-11
Abstract: A communication system and method are provided for equalizing delay of transmission paths in a distributed antenna network. The distributed antenna network includes a plurality of remote antenna units, a central unit or a base station connected to the remote antenna units by transmission media, where each connection between the base station and one of the remote antenna units forms a separate transmission path having an associated delay time, a delay detector for determining the associated delay time of the separate transmission paths for each of the remote antenna units, and a delay compensator for adjusting the associated delay times in response to the delay detectors so that all of the associated delay times are substantially equalized. The system and method allow the delay parameters for the entire network to be set upon installation and then to be periodically updated without physical intervention by an operator. The detection and compensation allow for equalization of delay time differences that could not otherwise be compensated in the base stations of mobile stations of conventional systems and methods. Furthermore, the equalization synchronizes the bursts so that air frame timing between cells served by the remote antenna units is enhanced and the hand-off performance therebetween is improved.

IPC: C08F210/06
Filed: 1997-08-25
Abstract: L'invention concerne en général des polypropylènes cristallins, des procédés concernant leur fabrication et des procédés concernant leur utilisation sous forme de films orientés. L'invention concerne en particulier des compositions de polypropylène cristallin comprenant à la fois un homopolymère de propylène et un hétéropolymère de propylène. Lesdites compositions sont préparées au moyen de systèmes catalyseurs organométalliques comprenant au moins deux substances organométalliques, dans le cadre d'un processus de polymérisation impliquant la polymérisation séquencée ou parallèle d'un homopolymère de propylène et d'un hétéropolymère de propylène, processus au cours duquel on ajoute au propylène une faible quantité de comonomère, de préférence l'éthylène. Les polymères ainsi obtenus sont excellents pour une utilisation dans la production de films orientés biaxialement. Les films fabriqués à partir desdits polypropylènes présentent une plage de transformabilité beaucoup plus large et peuvent être étirés uniformément à des températures plus basses, par comparaison aux films fabriqués à partir de polypropylène classique.

IPC: B60C7/22
Filed: 1997-08-18
Abstract: A rubber tread covers an outside of a tire core having a diameter adapted for fitting on a rim of a wheel, and a peripheral groove is formed in the tire core along an outer peripheral top thereof to be expanded at its inner portion near the rim in an axial direction of a tire. A small load applied in a short time, such as a shock, is cushioned by an elastic bending deformation of that portion of the tire core, which surrounds the peripheral groove, and when a large load is to be born over a long term, the tire core undergoes bending deformation in the tread, accompanied by compressive deformation to provide cushioning. As a result, it is possible to exhibit a soft, elastic force as in a hollow tire without the sacrifice of a load resisting property of the solid tire to adequately cushion a shock from a road surface even when a vehicle in an unloaded condition runs.

Abstract: This invention relates to a liner for a paint tray. In particular, the liner of this invention is comprised of a film made of paint-impervious material which has a sufficient perimetrical extent to fit against the interior surface of a paint tray with its perimeter extending over the surrounding side walls of the paint tray and encircling the outer surface of the surrounding side walls. The film near the perimeter releasably grips the outer surface of the surrounding side walls of the paint tray to hold the film in place. In the preferred embodiment, the grip is an elastic band which biases the film near the perimeter towards the outer surface of the surrounding side walls of the paint tray. Moreover, the elastic band is sewn on the film around the perimeter. This invention also discloses a method for lining a paint tray so that it may be reused without the necessity of cleaning formerly used paint from the tray.
