Abstract: A method and system for simulating and optimizing land seismic survey operations. The method and system utilizes spatially referenced data relevant to land seismic survey operations such as high resolution satellite and airborne imagery, processes the spatially reference data into a terrain map, uses discrete event information about the land seismic survey operation to simulate a land seismic survey. The output of the simulation is a detailed list of survey events. Mathematical optimization techniques are used in many aspects and in relation to the discrete event simulation. The invention uses a discrete event simulator which is an object-oriented software program with survey geometry objects that represent the survey design, resources objects that represent resources needed to conduct survey operations and manager objects to coordinate the resource objects within the specified survey geometry.

Title: Input buffer type packet switching equipment
Inventor: HACHINOTA MASASHI
IPC: H04L49/111
Filed: 2001-01-05
Abstract: Input buffer type packet switching equipment, which can output cells to an external output line having a slower output line rate than a corresponding input line rate without having buffers in its output line sections, is provided. The input buffer type packet switching equipment provides M input line buffers that store cells inputted from M input lines temporarily in a state that one of the M input line buffers stores cells inputted from corresponding one of the M input lines, in this the M is an integer being 2 or more, an M × N crossbar type switch, which provides N output lines, for switching cells outputted from the M input line buffers based on a cross point on/off control signal, in this N is an integer being 2 or more. The input buffer type packet switching equipment further provides N output line sections, which are provided for each of the N output lines of the M × N crossbar type switch, for outputting cells applied switching at the M × N crossbar type switch to N external output lines, and an arbiter that outputs a connection permission signal to one of the M input line buffers based on connection request signals outputted from the M input line buffers, and also outputs the cross point on/off control signal to the M × N crossbar type switch, and outputs the connection permission signal at a designated slower timing interval than a normal timing interval to one input line buffer that outputs cells to an external output line whose output line rate is slower than a corresponding input line rate. With this, the timing interval outputting the cells from one of the M input line buffers to the M × N crossbar type switch is made to be wider than the normal timing interval, therefore buffers in the output line sections are not needed.

Abstract: Cette invention concerne un interrupteur de fin de course programmable à apprentissage destiné à être utilisé dans un système de mouvement qui assure la rétroaction passive à un dispositif de commande. L'interrupteur de fin de course programmable à apprentissage est capable de mettre en oeuvre le système de commande de mouvement pour qu'il fonctionne conformément à un profil de mouvement programmé par l'utilisateur. L'interrupteur de fin de course programmable à apprentissage est doté de la capacité ''d'apprendre'' avec précision et de commander les positions au niveau desquelles un système de mouvement change de vitesse, ainsi que le moment auquel le système entraîne un mécanisme mené à s'arrêter, par exemple. Le système est destiné à être utilisé dans des variateurs de vitesse, des systèmes d'entraînement hydrauliques, pneumatiques ou dans tout autre système pour lequel la commande de rétroaction passive est recherchée. Dans un environnement typique, l'interrupteur de fin de course programmable à apprentissage est relié à un arbre mené d'un dispositif de commande. Les sorties de l'interrupteur de fin de course programmable à apprentissage sont placées sur la position marche/arrêt en fonction de la position angulaire détectée de l'arbre mené. Ces sorties sont ensuite renvoyées à un dispositif de commande, tel qu'un dispositif de commande logique programmable ou DCLP, pour être utilisées en tant que rétroaction passive pour que le DCLP sache quand il doit mettre en oeuvre/arrêter le système de commande qui est spécifiquement un moteur, un système embrayage/frein. Le DCLP lance alors le mouvement des dispositifs de commande, l'interrupteur de fin de course programmable à apprentissage détectant et poursuivant ce mouvement, par l'intermédiaire de la rotation de l'arbre mené et du temps de cycle dont les sorties sont basées sur un profil de mouvement défini par l'utilisateur.
