초록 ▼

Spatially located ultrasound beacons are provided in known locations within a distributed communication system. The ultrasound beacons are configured to emit ultrasound pulses that can be received by client devices in ultrasound communication range of the beacons. The client devices are configured to analyze the received ultrasound pulses from the beacons to determine their time-difference of arrival and as a result, their location(s) within the distributed communication system. The client devices comprise inertial navigation systems (INS) that calculate client device location as the client device moves, and when received ultrasound signals are below a predefined threshold.

대표청구항 ▼

1. A client device configured to communicate in a distributed communication system, comprising: a controller;an ultrasound receiver coupled to the controller, the ultrasound receiver configured to receive ultrasound pulses over at least one microphone; anda radio-frequency (RF) transceiver coupled to the controller, the RF transceiver configured to wirelessly receive and transmit RF communication signals over at least one antenna;an inertial navigation system (INS) operatively coupled to the controller;the controller configured to: calculate a first position using received ultrasound signals; anduse the INS to calculate a second position from the first position when the received ultrasound signals are below a predefined threshold. 2. The client device of claim 1, wherein the controller is configured to calculate the position using received ultrasound signals by being configured to: record sound received from a plurality of ultrasound beacons over the at least one microphone over a defined period of time;filter the recorded sound about at least one ultrasound beacon frequency;recover a plurality of ultrasound pulses from the filtered recorded sound emitted from a plurality of ultrasound beacons in the distributed communication system;perform a time-difference-of-arrival analysis on the recovered plurality of ultrasound pulses; anddetermine a relative distance of the client device to the plurality of ultrasound beacons. 3. The client device of claim 1, wherein the controller is further configured to transform the recorded sound in a frequency domain to produce a spectrum of the recorded sound. 4. The client device of claim 3, wherein the controller is configured to filter the recorded sound by filtering the spectrum of the recorded sound about the at least one ultrasound beacon frequency. 5. The client device of claim 3, wherein the controller is further configured to transform filtered spectrum of recorded sound back to a time domain. 6. The client device of claim 5, wherein the INS comprises: at least one accelerometer;a compass; andat least one gyroscope. 7. The client device of claim 6, wherein the controller is configured to calculate a third position if the received ultrasound signals are subsequently above the predefined threshold. 8. The client device of claim 7, wherein the received ultrasound signals are received from a distributed antenna system. 9. The client device of claim 8, wherein the received ultrasounds signals are received staggered in time. 10.
