Granted: 2004-12-14
Abstract: Circuit amélioré d'excitation d'allumage de moteur à turbine. L'énergie accumulée dans un condensateur d'excitation est ensuite appliquée à la charge (bougie d'allumage) par un dispositif de commutation à thyristor d'un type nouveau, spécialement conçu pour les applications à impulsions. Ce dispositif de commutation est conçu et réalisé de manière à présenter, par exemple, une structure cathode/grille hautement interchiffrée. Ce dispositif de commutation semi-conducteur est activé de manière périodique par un circuit de déclenchement électromagnétique ou optoélectronique qui déclenche la libération de l'énergie accumulée dans le condensateur d'attaque qui s'applique au fil d'allumage et à la bougie. La présente invention introduit également une flexibilité nouvelle au stade du circuit générateur d'impulsion (PFN), éliminant ainsi la nécessité de dispositifs spéciaux de protection en sortie, tels que des inductances à sortie saturable. Grâce au rendement di/dt considérablement plus élevé du dispositif, des circuits d'impulsion de sortie haute tension peuvent être utilisés sans dommange pour le dispositif de commutation à semi-conducteur. Un modèle de réalisation de l'invention comporte un circuit de rétroinformation d'un type nouveau grâce auquel les circuits de synchronisation par thyristor (attaque) et de conversion continu-continu compensent les variations résultant de l'usure de la bougie d'allumage et des conditions dynamiques du brûleur, adaptant à la demande le rythme des étincelles d'attaque, la tension de sortie et l'énergie nécessitées par les conditions de charge dynamiques.

Abstract: A simplified dual connection system electrically interconnects the vehicles of a train.  The train features a trainline to be formed through series interconnection of a wire on each vehicle.          The  simplified  dual connection  system  includes  a  central computer, a connector control device on each vehicle and a pair of mateable connectors between each pair of vehicles of the train.     Each  pair  of  mateable  connectors  electrically interconnects the wires of each pair of adjacently disposed vehicles to form the trainline. When the mateable connectors are mated, a primary electrical path and a redundant electrical path are formed in that pair of connectors for the trainline.     Each connector has a bidirectional circuit that interconnects a main node and a backup node for the wire on the vehicle.  When a pair of connectors is mated, the main nodes of that pair interconnect  to  form  the  primary  electrical path  of  the trainline and the backup nodes of that pair interconnect to form part of the redundant electrical path of the trainline.  The redundant electrical path thus provides an electrical connection redundant  to  the  primary  electrical  path  to  which  it corresponds.   The connector control device in each vehicle determines the integrity of the primary electrical path in the pair of mated connectors.  The central computer receives from each connector control device the results of that determination and reports those results to a train operator.

IPC: G01B7/30
Filed: 1998-03-19
Granted: 2004-06-15
Abstract: In a device for detecting mirror position, there is provided a resistor substrate being located coaxially with a nut adjuster for adjusting an angle of incline of a mirror, and a contact member so as to rip the resistor substrate . The contact member slides in pine corresponding to the movement of the nut adjuster while the resistor substrate is fixed to a housing. Thus, as the nut adjuster slides, the contact member slides against the resistor substrate, which results the change of a contact position of the contact member and a long resistance Rl. Consequently, since a voltage level generated at the contact member changes, the angle of incline of the mirror can be determined by detecting this voltage level.      Inasmuch as the contact member and the resistor substrate are housed within a sliding block, there is no need for much space to locate the various parts in, and thus the whole device can be configured in a compact manner.      In addition, the fact that the resistance R1 is connected to the direct-current power source via resistances R2 and R3 means that the measured voltage level is acquired in the form of an intermediate value of the direct-current power source voltage. Subsequently, it is possible to reduce the influence of noise and other factors so that the mirror angle can be detected with a high degree of accuracy.

Abstract: In an image signal encoding system, a change point detecting device detects a change point of a switching request signal to produce a change point detecting signal as a B picture ban signal.  An encoding mode determining device periodically produces I picture mode signals, P picture mode signals, and B picture mode signals when the encoding mode determining device is not supplied with the B picture ban signal.  The encoding mode determining device produces an I picture signal in response to the B picture ban signal.  The encoding mode determining device produces the I picture mode signal in an initial image plane frame of the editing image signal after a switching time point of selection of a first input dynamic image signal and a second input dynamic image signal in response to the B Picture ban signal.  The encoding mode determining device produces the P picture mode signal in a final image plane frame before the switching time point of selection of the first input dynamic image signal and the second input dynamic image signal in response to the B picture ban signal.  A register produces, by retiming the switching request signal in using the I picture signal which is produced in response to the B picture ban signal, a switching signal.  A selector selects, as an editing image signal, one of the first input dynamic image signal and the second input dynamic image signal in response to the switching signal.  An image encoding device encodes,  in the I picture mode,  the initial image plane frame of the editing image signal after the switching time point of selection.  The image encoding device encodes, in the P picture mode, the final image plane frame before the switching time point of selection.

Title: High-penetration transmission method for a radiocommunication system
Inventor: CHENNAKESHU SANDEEP
IPC: H04B7/185
Filed: 1996-12-23
Granted: 2004-04-06
Abstract: A method and system for increasing the signal margin of a radiocommunication link to provide a short message service which is reliable, even under non-ideal conditions. According to the method, short alphanumeric messages can be transmitted over the broadcast control channel of a digital radiocommunication link, or another communication channel consisting of one or more slots from successive frames in a TDMA communication link. An increase in transmission power is used in combination with repetition to increase effective signal margin without complications in the mobile unit design, significant delay, or co-channel interference. Where a more significant increase in signal margin is desired, when a longer message is required, or for voice messages, the message may be stored and the mobile unit alerted of the message.
