摘要： 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.

摘要： A method and device for non-echo ultrasonic Doppler used for corrected inertial navigation includes providing at least one ultrasonic emitter within an environment, each emitter configured for transmitting an ultrasonic tone of a predefined frequency. An initial location of the mobile device is established within the environment. Dead reckoning procedures are initiated using sensors within the mobile device. The device receives at least one ultrasonic tone from an emitter, and converts the at least one ultrasonic tone into a digital waveform. The device determines at least one peak frequency of the digital waveform, and subtracts the at least one peak frequency from each predefined frequency to determine at least one Doppler shift, which is used for correcting the dead reckoning of the mobile device.

摘要： A technique for non-echo pulsed ranging of a mobile device within an environment includes a plurality of emitters within the environment transmitting signal pulses of a predefined frequency to a mobile device that can receive a signal pulse, convert the signal pulse into a digital waveform, store the digital waveform into a buffer having a predetermined length of time, and analyze the digital waveform to detect a signal pulse at the predefined frequency. If a signal pulse is detected, the mobile device can re-analyze the digital waveform that was stored in the buffer to see if another signal pulse can be detected within the waveform, indicating the existence of a reflected signal. If another signal pulse is detected, the mobile device can select the signal pulse that was received first in time, i.e. the direct signal, for use in ranging of the mobile device.

摘要： A method and system for orientation compensation of a mobile device within an environment includes providing a plurality of reference markers having straight edges and having a defined, regular orientation with respect to the environment. Information about the orientation of the reference markers is supplied to a mobile device operating within the environment. An orientation sensor disposed within the mobile device estimates an orientation of the mobile device. An image of one reference marker is captured, and at least one edge of that reference marker is located. The estimated orientation is compensated by correcting for the reference marker orientation and aligning the corrected estimated orientation to the at least one edge of the reference marker that is closest to being parallel to the corrected estimated orientation.

摘要： Using counter offsets to allow flight time calculation in an ultrasonic locationing system includes ultrasonic transmitters for emitting ultrasonic bursts, each transmitter having a counter and a synchronization server. A backend controller schedules periodic bursts from each transmitter. A mobile device also has a counter and can receive the ultrasonic bursts, wherein the mobile device can determine a relative counter offset between itself and a transmitter. The mobile device can calculate a corrected reception time of ultrasonic bursts from the transmitters based on the counter value when the burst is detected and the relative counter offset between the mobile device and the transmitter, and report the corrected time to the backend controller for locationing of the mobile device.
