Abstract:
Sistema de localización o seguimiento en tiempo real, de personas y objetos móviles en el interior de túneles, con alta densidad infraestructura!, mediante la estimación de longitudes, ángulos o patrones, obtenidos a través de señales electromagnéticas, caracterizado porque el sistema de localización en tiempo real (WILOS-RTLS), está conformado por cuatro medios esenciales para realizar localización, un switch Ethernet fibra óptica/UP (1), unos dispositivos fijos RTLS (2), un dispositivo TAG móvil dispuestos en maquinarias y personal (5) y un Software de cálculos de localización (6); los dispositivos RTLS (2) reciben una señal inalámbrica interfaz RF (4) correspondiente del dispositivo móvil Tag (5) de posición desconocida, quien emite su señal RF a intermitencia del orden de los mseg; cuando a los menos dos dispositivos fijos RTLS (2) reciben de la señal inalámbrica interfaz RF (4) desde el dispositivo móvil (Tag móvil en maquinaria o persona) (5), estos estiman el tiempo diferencial de arribo de la emisión de Interfaz RF (4) (TDoA), para luego enviar la información estimada, a través de la infraestructura de red cableada mediante un switch Ethernet fibra óptica/UP o inalámbrica (1) mediante (interfaz RF entre dispositivos fijos) (3), hacia un software de cálculos de localización (6); de esta forma, la información recibida desde a lo menos de dos dispositivos RTLS (2) (una dimensión), o tres (dos dimensiones) o cuatro (tres dimensiones), es procesada en el software (6), para aplicar técnicas matemáticas de lateración apoyada en la información de TDoA; finalmente, una vez estimada la posición en dicho software (6), se tiene esta información para ser utilizada en cualquier aplicación que grafique y adapte a una interfaz acorde al escenario de localización.
Abstract:
Geographical and space positioning system and process, comprising:a first, a second, and a third base (A, B, C) which are fixed in relation to the earth, but spaced away and disaligned in relation to each other; a space platform (S) which is visible from the fixed bases (A, B, C);at least one target (P) situated on or above the surface of the earth; a transmitter (1)operatively associated with each of the parts defined by the fixed bases (A, B, C) and the space platform (S) in order to emit pulses in a determined frequency, each pulse in a predetermined reference instant; a receiver (2)operatively associated with: each fixed base (A, B, C), each target (P) and with the transmitter (1) in order to receive said pulses in a trajectory covering the distance between the space platfom (S) and the fixed base (A, b, C) associated with the receiver (2) a control unit (3) which is operatively connected to both the transmitter (1) and the receiver (2) in order to calculate, for each pulse emission instant, the lateral edges of the tetrahedron, whose vetices are defined by the three fixed bases (A, B, C) and by the space platform (s), based upon the determination of the propagation time of each pulse in said trajectory , between the space platfom (S) and each fixed base (A, B, C), in order to allow determining a respectice extension of the trajectory of the space platform (S), while the latter is visible by the fixed bases (A, B, C) and determining, at the same time, its equation of motion, allowing calculating the possible positions of the target (P) in the control unit (3) and in the target (P) itself.
Abstract:
A system for providing integrated communications, navigation and surveillance capabilities. A space segment comprises a plurality of time synchronized satellite broadcasting navigation signals and have two-way communication capabilities. Each satellite also has communication switching capabilities and is part of a network. A terrestrial segment comprises processing apparatus that communicates the satellite through the network. A user segment comprises at least one mobile user device capable of two way communication with the plurality of satellites and of using the navigation signals to derive its position. The user device broadcasts surveillance signals which the processing apparatus uses to derive the position of the user device. The signals are also used by the system to measure and transmit the state of the ionosphere.
Abstract:
A combined method for locating mobile stations using a measurement of the phase of carrier-modulating tones on the outbound link and a pseudo-random code spread spectrum for timestamping message reception on the inbound link. The method is useful for locating a variety of mobile stations on land, at sea, in the air, etc.
Abstract:
The present invention is directed to a bio-fluid detector such as a hemoglobin detector having the capability of receiving, storing and transmitting health information utilizing a portable transmitter and receiver including electronic PDAs such as cell phones. Further, the present invention utilizes a non-invasive hemoglobin detector that is connected to a portable transmitter-receiver such as PDAs including, but not limited to, cell phones.
Abstract:
Communication method for an aircraft (1) comprising the steps of: installing a security system (100 or IDDS) in a non-pressurized zone (2) of the aircraft (1), said security system (100) comprising a GPS localization device (101) with satellite link and an autonomous battery (102); detecting in the GPS localization device (101) at least one position (A) of the aircraft; sending the position (A) to a control station (200) interconnected with the satellite link; said steps of detecting and sending the position (A) being performed if an anomaly is detected.
Abstract:
A machine for cleaning a ballast bed has, in front of a take-up device (3) relative to a working direction (9), a first signal receiver (12) - suitable for position determination in a global navigational satellite system - for scanning an actual track position. A second signal receiver (13) connected to the machine (1) for scanning a new track position created by laying down the raised track (2) onto the re-applied ballast bed (4) is arranged downstream. Both signal receivers (12, 13) are associated with a control device (14) designed to act on the drives (10) that displace a track-lifting device (11) relative to the machine frame (8).
