    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: 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: The duty cycle of a portable battery-powered RFID tag reader is reduced during time periods when it is less likely to produce a "read" in order to preserve battery life. The reader operates with an aggressive duty cycle during periods of a high probability of a tag read and reduces duty cycle during periods of a low probability of a tag read. In this manner a user does not perceive the reader to be sluggish. An alternative embodiment reduces peak operating power during time periods when a tag is less likely to produce a "read" in order to preserve battery life.

    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.
