Abstract: La présente invention concerne un procédé (500) et un système (100, 600, 700) fonctionnant selon un principe de différentiels d'heure d'arrivée ou "TDOA" (Time Difference Of Arrival) et permettant d'évaluer la position d'un premier terminal du service radio mobile (108) intégré à un système radio mobile (100, 600, 700). Ce système, qui fonctionne à base de mesures d'heures d'arrivée ou "TOA" (Time Of Arrival), comporte notamment une pluralité de stations de base radio (BS1, BS2, BS3), des appareils de mesure (130), un contrôleur de réseau (110) et un noeud de service (103). Les appareils de mesure (130) mesurent la TOA à la demande et éventuellement le sens d'arrivée ou "DOA" (Direction of Arrival), et ce, à l'occasion d'un créneau temporel amont numérique (301 et 302), ou d'une information numérique concernant un canal trafic amont analogique d'une ou plusieurs stations de base radio (BS1, BS2 et BS3). Les données TOA et DOA ainsi que le N DEG  de canal trafic sont signalés à un centre de commutation des services mobiles (102), lequel centre extrait du N DEG  de canal trafic l'identité du premier terminal mobile (108) et envoie à un noeud de service (103) l'identité du terminal et les informations de mesures TOA et DOA. Le noeud de service (103) calcule la position du premier terminal radio mobile (108) en utilisant l'information TOA (complétée le cas échéant de l'information DOA). Un deuxième terminal radio mobile (601) est également situé sur la même plate-forme mobile (automobile, véhicule de secours, etc...) que l'une des stations de base radio (BS1, BS2 ou BS3), laquelle plate-forme peut être amenée très près du premier terminal mobile (108). Il en résulte qu'en amenant l'une des stations de base radio (BS1, BS2 ou BS3) près de la région étudiée (près du premier terminal mobile (108)), on améliore de façon notable la précision de détermination de la position.

Abstract: The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber contains a float operably connected to a mechanical alarm. The float, as the chamber is emptied of liquid, reaches a position wherein a "low or empty product" signa l is generated. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.

Title: Device for folding leading end of net-type bale wrapping material to enhance its full-width conveyance into the baling chamber
Inventor: PHILLIPS KENNETH CRAIG
IPC: B65B11/56
Filed: 2000-06-16
Granted: 2006-01-10
Abstract: A large round baler is equipped with a net wrap feeding mechanism mounted to the rear and bottom of the bale discharge gate. The feeding mechanism includes upper and lower feed rolls, with the lower roll being located closer to the discharge gate than the lower roll and, the pair of rolls thus being arranged to deliver wrapping material against an upright run of bale forming belts, the latter acting to carry the net to a pinch point formed between the belts, where they pass around a lower rear belt support roll, and a guide pan of a net material guide assembly that extends beneath and adjacent a lower run of the belts. A net wrap material cut-off device includes a fixed knife blade located forwardly of and extending parallel to the lower feed roll. The cut-off device further includes a pair of transversely spaced cut-off arms between which extend and to which are fixed an anvil. The arms are mounted for pivoting between a raised standby position, wherein the anvil is located adjacent the upper feed roll and a lowered cut-off position, wherein the anvil is engaged with the knife blade. A row of bristles is located between the lower feed roll and the knife blade at a position where it acts to strip the lower roll of net material having a tendency to wrap about the lower roll and to entangle the net material as the latter is brought against the bristles during severing of the net material tensioned between the feed rolls and the pinch point after a bale has been wrapped. The entangled net material results in the leading end of the net material becoming folded back on itself at the beginning of the next wrapping cycle, such doubling together with the operation of spreader rolls acting to deliver the net material to the baling chamber at its full width.

Abstract: Methods of predicting a propensity to develop prostate cancer are presented.  The method consists of measuring the IGF status of an individual. Individuals with high IGF status, as compared with normal reference range values, are at increased risk for developing prostate cancer. More particularly, the IGF status may be determined by measuring IGh-I  levels and/or IGFBP-3 levels. High IGF and low IGFBP levels are indicative of a high IGF status. A method of determining the prognosis of existing prostate cancers or of monitoring disease progression involves determining the IGF/PSA status of an individual.  Individuals with a high IGF/PSA status (both high IGF status and high PSA levels) tend to develop severe prostate cancer and have a poorer overall prognosis.

Title: Methods and apparatus for self-diagnosing electronic price labels
Inventor: BHYRAVABHOTLA RAGHURAMA
IPC: G06Q30/06
Filed: 2000-10-12
Granted: 2006-10-10
Abstract: A self-diagnosing electronic price label. The label communicates with a central processor in order to receive price information for display and to report the status of the label to the central processor. The label periodically runs a self-test program to verify proper operation of its components. If a component fails the self-test, the failure is reported to a central processor, and the central processor reports the failure for investigation. During normal operation, the label issues a signal to the central processor indicating normal operation. In the event of a failure, the label ceases to send the signal indicating normal operation. When the signal is not received as expected, the central processor reports the failure to receive the signal for investigation. This allows the central processor to be alerted to failures which disable communication between the label and the central processor.
