Title: Procede et circuit de reception de signaux de positionnement par satellites avec elimination des erreurs de multitrajets
Inventor: RENARD ALAIN
IPC: H04B1/707
Filed: 1996-12-12
Abstract: L'invention concerne les récepteurs de positionnement par satellite. Pour réduire l'effet néfaste des trajets réfléchis sur la mesure de position GPS qui ne devrait prendre en compte que le trajet des signaux radiofréquence en ligne directe, on propose selon l'invention un procédé permettant par simple calcul d'extrapolation d'éliminer l'influence des multitrajets. On effectue des mesures par corrélation avec quatre codes pseudo-aléaoires E1, E2, L1, L2 répliques d'un code reçu d'n satellite. On effectue un premier ensemble de mesures d'énergies de corrélation et de temps reçu avec les codes E1, L1 correspondant à une avance et un retard d par rapport à un code ponctuel, et un deuxième ensemble de mesures avec les codes E2, L2 correspondant à une avance et un retard k.d (k différent de 1 et de 0). Par extrapolation linéaire, on en déduit les mesures pour k= 0, qui correspond au cas où les multitrajets n'ont pas d'effet. L'invention peut être mise en oeuvre avec une seule boucle d'asservissement de code pseudo-aléatoire ou deux boucles indépendantes.

Title: Universal charging station and method for charging electric vehicle batteries
Inventor: NOR JIRI K
IPC: H02J7/00
Filed: 1995-07-06
Abstract: A method and apparatus for charging the battery (84) of an electric vehicle (80) are provided. When the electric vehicle is connected to a charging station (82), it is interrogated to determine the nature of the charge controller (86) that is on board the vehicle; and logic decisions invoking the particular mode for charging the vehicle are made depending on the nature and type of charge controller that is on board the vehicle. Thus, delivery of charging energy to the battery (84) in the vehicle may be entierely under the control of a charge controller on board the vehicle (86); or if the control module in the vehicle is less sophisticated then delivery of charging energy will be under the control of a charging module within the charging station.  Parameters of initial charging current and voltage are therefore set either by the on board battery charging controller, or the charge controller in the charging station; alternatively, those parameters may be set manually or by insertion of a card into a data interface to establish initial charging conditions. Under controlled conditions, a plurality of vehicles may be charged at a single establishment having a plurality of charging stations, either sequentially or simultaneously, depending on the cirteria to be established. The charging station may be privately owned, so as to charge a fleet of vehicles; or there may be a plurality of charging stations at a publicly accessible service station.

A dispenser (30) has a compartment (32) formed by a wall (31) for containing a beneficial-agent (33) to be delivered. A laser beam is employed for burning at least partially through the wall (31). The laser beam and the dispenser (30) are positioned relative to one another such-that the laser beam is aimed at a predetermined port site (35) on the dispenser (30). The laser beam is turned off (unenergized) during the positioning period. The laser beam is then energized and moved relative to the dispenser (30) for scribing a delivery port (37) proximate the port site (35). The scribing motion moves the laser beam from the port site (35) along a course (37). Preferably the course (37) is closed. The scribing motion causes the burning of the wall (31) by the laser beam to scribe the delivery port (37). The positioning motion and the scribing motion are controlled by a scanning system (16). The laser source (13) beam is energized during the scribing motion for burning the wall (31) forming the delivery port (37) therein for subsequent delivery of the beneficial agent (33) therethrough.

Title: Diversity gain controlled cell-site transmission to prevent traffic signals from propagating beyond reachable extent of control signals
Inventor: AZUMA TOMOHIRO
IPC: H04B7/24
Filed: 1997-07-16
Abstract: A cell-site base station apparatus comprises an array of diversity antennas for receiving multipath components of a mobile-transmitted signal. Receivers, connected to the antennas, produce strength indication signals and demodulated signals. For transmission of a control signal from the cell-site to a mobile station, a variable gain transmitter is coupled to one of the antennas and the control signal is sent at a first power level. When a connection is established for the mobile station, the strength indication signals from the receivers are examined to detect a highest strength value and one of the antennas is selected at which the multipath component of the highest strength value is arriving. The transmitter is then switched to the selected antenna for transmitting traffic signals and the gain of the transmitter is set to a second power level lower than the first power level to compensate for the transmit diversity gain of the selected antenna.

Title: Latching device for a door of a railway train stop housing
Inventor: STERLING MIKE EDWARD
IPC: E05C17/48
Filed: 1997-07-18
Abstract: A latching device is provided for releasably retaining in an upright and open position, a hinged door which is typically manufactured of a heavy cast iron and hinged to a train stop housing, thereby to prevent the unintentional and accidental closure of the hinged door during installation connections or any field operational maintenance of the train stop housing. Preferably, a latch assembly is mounted atop a sturdy frame which provides an integral support above the train stop housing and is mountable with mounting hardware to a mounting lug of the train stop housing. The latch assembly includes a covered latching bar which slides in a channel defined by a first and second bracket and is urged by a spring mounted between the first and second bracket, thereby to urge a latch end of the latching bar outwardly away from the latch assembly and an opposing handle end of the latching bar inwardly towards the latch assembly. The latching device is mounted to the train stop housing so that a hinged door which is rotated toward the integral support of the frame slides against the latch end and urges the latch end inwardly toward the latch assembly against the urging of the spring, until the door is moved past the latch end and the spring snaps the latch end outwardly away from the latch assembly, thereby to obstruct the door from unintentionally and accidentally being closed past the latch end, so that the door is positioned between the latch end and the support of the frame. When closing of the door is desired, the handle end of the latching bar may be manually grasped, thereby to urge the handle end outwardly away from the latching assembly and to retract the latch end inwardly towards the latch assembly to clear the latch end obstruction which prevents closing of the door.
