Abstract: L'invention concerne un système d'approche de détection de différentiel permettant de communiquer sans connaître les paramètres d'un canal, un émetteur comprenant un nombre d'antennes émettrices supérieur à deux. Chaque bloc de bits de l'émetteur est mis en correspondance avec un vecteur traité de façon à développer un vecteur de symboles, par utilisation de vecteurs mutuellement orthogonaux et du vecteur de symboles du bloc précédent. Le vecteur de symboles est appliqué à un bloc de mise en correspondance temps-espace, et donc aux antennes émettrices. Les signaux d'un bloc reçus au niveau d'un récepteur, sont formés dans un vecteur combiné à un vecteur correspondant provenant du bloc précédent en fonction des vecteurs mutuellement orthogonaux. Le vecteur combiné est ajouté aux vecteurs des autres antennes de réception, et le résultat ajouté est appliqué à un module de décodeur de distance minimum. Ce module de décodeur sélectionne le vecteur le plus probable, et ce vecteur est appliqué à une mise en correspondance permettant de récupérer les bits émis.

Title: Cargo sensing system and method
Inventor: RAGLAND RICHARD
IPC: G01S7/00
Filed: 2001-04-13
Granted: 2013-04-02
Abstract: A method and apparatus for determining whether cargo is present in a freight car. The freight car has a proximal ("rear") end with a loading door and opposing, distal ("front") end. One or more transmitters and receivers are mounted inside the freight car at the front end, toward the car's ceiling. The transmitters/receivers are operated by a controller, which also functions to analyze data from the transmitters/receivers and transmit related reports to a remote monitoring site. During a prescribed time period, a transmitter generates an ultrasonic signal pattern with a coverage area of prescribed radius that terminates before reaching the loading door. During the time period of transmission, or slightly later to account for signal reflection time, the controller operates the receiver to detect reflected signals originating from the transmitter. Then, the controller transmits a report of whether cargo is present in the freight car, based on whether any reflected signals were received.

Granted: 2010-02-16
Abstract: A method of scrubbing lower mass sulfides with a sulfide scrubbing medium capable of regeneration. The sequential order of gas flow through three vessels is altered. A first of the three vessels is maintained in a scrubbing mode, scrubbing to breakthrough sulphides from the gas that passes through it. A second of the three vessels is maintained in a conditioning mode. Sulfide scrubbing medium in the vessel removes any residual sulphides from the gas while being conditioned by such limited exposure to the sulphides. A third of the three vessels is maintained in a regeneration mode. Saturated sulfide scrubbing medium in the vessel removes excess oxygen from the gas while being regenerated by such exposure to oxygen.

Abstract: A pile is installed in a drilled hole in the ground by inserting a tube extending to the bottom and providing on the bottom end of the tube a bottom shoe for compressing material at the bottom of the hole. A drive tool attached to the upper end of the tube applies downward compression and reciprocating rotation forces to the tube. A hammer by-passes the drive tool to apply impact forces to an upper surface of the shoe at the bottom of the tube acting to drive the shoe in downward movement so that the shoe slides downwardly relative to the tube. A radial surface of the shoe causes compressive forces on the material at the bottom of the hole and blades on the radial surface when reciprocated back and forth by the tube cause break up of the compressed material to allow repeated compression and significantly increased supported loads on a pile which is applied with the tube removed and is supported on the shoe.
