Abstract: A system and method for orientation of an ultrasonic signal includes at least two emitters in a mobile device that includes an orientation sensor that can determine a device orientation. A receiver at a fixed, known point includes at least two microphones operable to receive an ultrasonic signal from the device. The mobile device can drive the emitters to produce an ultrasonic signal that is oriented towards the receiver. A location engine can establish a location of the mobile device using the time delay of arrival of an ultrasonic burst from the mobile device impinging on each microphone of the receiver. In response to the location and/or the orientation, the mobile device operable to drive the emitters to produce a signal that is oriented towards the receiver.

Abstract: An apparatus and method for locating a mobile communication device 100 includes sending ultrasonic or radio frequency signals 140,141 from a plurality of fixed transmitters 116 to that device. An imaging device 117 possibly collocated with the transmitter correlates images of the user carrying the mobile device with the positional information and recognises when the signal from the transmitter is obstructed (20, fig.3). Time of arrival (TOA) or signal strength (RSSI) measurements may be used to locate the mobile device and transmit power levels or mobile device signal threshold levels may be varied; a planogram of the area may be also be used to estimate signal attenuation from obstructions to mitigate multipath effects. The locating system may periodically update to allow tracking of the mobile device.

Abstract: A dual frequency ultrasonic locationing system includes an emitter (106) operable to emit two different ultrasonic frequencies (610-616) simultaneously in one ultrasonic burst (140). A receiver (110) with at least two microphones (116) is operable to receive the ultrasonic burst. A correlator (20) is operable to correlate the signals obtained from each microphone to derive a time difference of arrival of the ultrasonic burst at each microphone. The time difference of arrival of the ultrasonic signal from the emitter impinging on each microphone of the receiver is utilized to determine a location of the emitter.

Abstract: Ein System und Verfahren zum Orientieren eines Ultraschallsignals umfasst mindestens zwei Sender in einem mobilen Gerät, das einen Orientierungssensor umfasst, der eine Geräteorientierung bestimmen kann. Ein Empfänger an einem festen bekannten Punkt umfasst mindestens zwei Mikrofone, die betreibbar sind, um ein Ultraschallsignal von dem Gerät zu empfangen. Das mobile Gerät kann die Sender ansteuern, um ein Ultraschallsignal zu erzeugen, das zu dem Empfänger hin orientiert ist. Eine Ortungsmaschine kann unter Verwendung der Laufzeitdifferenz eines auf jedes Mikrofon des Empfängers auftreffenden Ultraschallstoßes von dem mobilen Gerät einen Standort des mobilen Geräts feststellen. Als Reaktion auf den Standort und/oder die Orientierung, ist das mobile Gerät betreibbar, um die Sender anzusteuern, um ein Signal zu erzeugen, das zu dem Empfänger hin orientiert ist.

Abstract: Ein Dualfrequenz-Ultraschall-Lokalisierungssystem enthält einen Emitter (160), funktionsfähig, um gleichzeitig zwei verschiedene Ultraschallfrequenzen (610–616) in einem Ultraschallburst (140) auszugeben. Ein Empfänger (110) mit wenigstens zwei Mikrofonen (116) ist funktionsfähig, um den Ultraschallburst zu empfangen. Ein Korrelator (20) ist funktionsfähig, um die von jedem Mikrofon empfangenen Signale zu korrelieren, um so eine Zeitdifferenz des eingehenden Ultraschallbursts an jedem Mikrofon abzuleiten. Die Zeitdifferenz des eingehenden Ultraschallsignals vom Emitter, das auf jedes Mikrofon des Empfängers trifft, wird eingesetzt, um die Position des Emitters zu bestimmen.

Abstract: An ultrasonic locationing system using a dual phase pulse includes an emitter emitting two consecutive frequency bursts, each having a different phase, within one ultrasonic pulse. A receiver microphone receives the ultrasonic pulse, and a processor runs an amplitude-based detection algorithm on the pulse for a band of frequencies of interest and detects a first burst of the pulse within the proper frequency band and having an amplitude exceeding a threshold. Whereupon, the processor determines a relative phase difference between the first burst and a second burst of the pulse and determines whether the relative phase difference is within a predetermined acceptance window, indicating that the pulse is valid for use in locationing the emitter and associated mobile device.

Abstract: Eine Vorrichtung und ein Verfahren zur videounterstützten Feststellung eines mobilen Kommunikationsgeräts mit Sichtverbindung in einem Ortungssystem umfassen das Senden von Signalen von mehreren festen Sendern in der Umgebung zu einem nahegelegenen mobilen Kommunikationsgerät, um das mobile Kommunikationsgerät zu orten. Eine Bildgebungsvorrichtung beobachtet das mobile Kommunikationsgerät oder einen das mobile Kommunikationsgerät tragenden Benutzer in der Umgebung und erkennt, wenn sich das mobile Kommunikationsgerät nicht in einem Zustand mit Sichtverbindung zu mindestens einem nahegelegenen Sender befindet, wobei ein Signal von dem mindestens einen nahegelegenen Sender blockiert ist. Ein Ortungssystemparameter wird für dieses blockierte Signal derart modifiziert, dass das mobile Kommunikationsgerät unter Verwendung des modifizierten Ortungssignalparameters geortet werden kann.
