摘要： Techniques for controlling a process to prevent injury are presented. The techniques include obtaining a location estimation of a mobile transmitter affixed to an object, where the location estimation is relative to a location of a fixed receiver, and where the obtaining the location estimation includes sending an ultra wideband communication from the mobile transmitter to the fixed receiver and acquiring the ultra wideband communication by a phased antenna array of the fixed receiver; assessing, based on the location estimation, that the mobile transmitter is within an impermissible location; determining that the location estimation is sufficiently accurate based on a distance between the location estimation and the fixed receiver; and interrupting the process upon both assessing that the mobile transmitter is within an impermissible location and determining that the location estimation is sufficiently accurate.

The first interrogator includes a transmit antenna; a first receive antenna, and circuitry configured to generate, using radio-frequency (RF) signal synthesis information received from the synchronization circuitry, a first RF signal for transmission by the transmit antenna, and generate, using the first RF signal and a second RF signal received from a target device by the first receive antenna, a first mixed RF signal indicative of a distance between the first interrogator and the target device. The second interrogator includes a second receive antenna, and circuitry configured to generate, using the RF signal synthesis information, a third RF signal; and generate, using the third RF signal and a fourth RF signal received from the target device by the second receive antenna, a second mixed RF signal indicative of a distance between the second interrogator and the target device.

摘要： L'invention concerne un procédé de transmission de paramètres de vol d'un aéronef meneur (L) à au moins un aéronef intrus (I). Selon l'invention, la transmission est effectuée au moyen d'un système d'évitement de collision de type TCAS auquel est connecté un système d'autorisation d'émission de paramètres de vol ayant une base de données comprenant des coordonnées définissant un volume, dit volume de confiance (C), inférieur au volume de surveillance du TCAS. Le système d'autorisation d'émission de paramètres de vol de l'aéronef meneur autorise, uniquement pour un aéronef intrus identifié comme volant dans le volume de confiance, la transmission d'au moins un paramètre de vol de l'aéronef meneur de sorte que ce l'aéronef intrus puisse calculer la position de centres de tourbillons de sillage (14L, 15L) générés par l'aéronef meneur (L) ou la force de circulation desdits tourbillons de sillage (14L, 15L) .
L'échange de paramètres de vol de l'aéronef meneur uniquement vers des d'aéronefs intrus volant dans le volume de confiance de dimensions restreintes permet de ne pas dépasser la capacité maximale de la bande passante de la communication automatisée.

摘要： The subject system aggregates, or stitches, multiple component channel estimates to generate an aggregated wideband channel estimate that can be used to determine more accurate time of arrival estimations than those determinable from the individual component channel estimates. The subject system also provides for multipath detection on a single channel or an aggregated channel that may be used to facilitate an accurate time of arrival estimation. For example, information derived from the multipath detection may be used to supplement and/or enhance a time of arrival estimation algorithm. The subject system also provides a sounding protocol that allows devices to perform one or more signal exchanges to facilitate generating the aggregated wideband channel estimate and/or to facilitate performing the multipath detection. The protocol allows the devices to perform signal exchanges over one or more channels within a coherence time, and also provides for security mechanisms as well as failure recovery.

摘要： Disclosed are various approaches for determining a location using guided surface waves. A wavelength and a phase of a base guided surface wave launched from a ground station and received by the guided surface wave receive structure are identified. A range of an overlaid guided surface wave launched from the ground station and received by the guided surface wave receive structure are identified., wherein the range of the overlaid guided surface wave is measured as a number of wavelengths of the base guided surface wave. A distance of the guided surface wave receive structure from the ground station based at least in part on the phase of the base guided surface wave and the range of the overlaid guided surface wave is calculated. Finally, a location of the guided surface wave receive structure based at least in part on the distance of the guided surface wave receive structure from the ground station is determined.

摘要： Disclosed are various embodiments for fixing a navigational position using guided surface waves launched from guided surface wave waveguide probes at various ground stations. A guided surface wave is received using a guided surface wave receive structure. A reflection of the guided surface wave is received using the guided surface wave receive structure. An amount of time that has elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave is calculated. A location of the guided surface wave receive structure is determined based at least in part on the amount of time elapsed between receiving the guided surface wave and receiving the reflection of guided surface wave.

摘要： Systems and methods are provided for determining a user context based on one or more wireless signals. In particular, location data can be determined by a user device. The user device can then detect beacon data broadcast by a first set of beacon devices, and subsequent to detecting the first beacon data, second beacon data broadcast by a second set of beacon devices. The location data can be compared with the first beacon data and the second beacon data to determine a user context. In particular, a context can be determined based at least in part on whether the location data is indicative of a changing location of a user, and whether the second beacon data corresponds to a change in beacon data from the first beacon data.

摘要： An apparatus estimates successive headings of a mobile device based on respective results of measurements by the mobile device on radio signal transmitted by a plurality of transmitters to obtain estimated headings (201). It computes a mean heading based on a predetermined number of the estimated headings and computing a standard deviation of the predetermined number of estimated headings (202). It determines whether the mean heading is to be considered valid based on the computed standard deviation of the estimated headings (203). Finally, it provides an indication of the mean heading as an indication of a current heading of the mobile device for use by a specific application only if the mean heading is determined to be considered valid (204).

摘要： Spectral components of waves having one or more properties other than phase and amplitude that vary monotonically with time at a receiver, and provide retardations or lags in the variation in proportion to the times or distances travelled from the sources of the waves to the receiver. The lags denote the property values prior to departure from a source and are absent in its proximity. Orthogonality of the lags to modulated information makes them useful for ranging and for separation or isolation of signals by their source distances. Lags in frequencies and wavelengths permit multiplication of capacities of physical channels. Constancy of the lagging wavelengths along the entire path from a source to the receiver enables reception through channels or media unusable at the source wavelengths, as well as imaging at wavelengths different from the illumination.
