APPARATUS, SYSTEM, AND METHOD FOR DETECTING PHYSIOLOGICAL MOVEMENT FROM AUDIO AND MULTIMODAL SIGNALS
Publication number: 20210275056Abstract: Methods and devices provide physiological movement detection with active sound generation. In some versions, a processor may detect breathing and/or gross body motion. The processor may control producing, via a speaker coupled to the processor, a sound signal in a user's vicinity. The processor may control sensing, via a microphone coupled to the processor, a reflected sound signal. This reflected sound signal is a reflection of the sound signal from the user. The processor may process the reflected sound, such as by a demodulation technique. The processor may detect breathing from the processed reflected sound signal. The sound signal may be produced as a series of tone pairs in a frame of slots or as a phase-continuous repeated waveform having changing frequencies (e.g., triangular or ramp sawtooth). Evaluation of detected movement information may determine sleep states or scoring, fatigue indications, subject recognition, chronic disease monitoring/prediction, and other output parameters.Type: ApplicationFiled: September 19, 2017Publication date: September 9, 2021Applicant: RESMED SENSOR TECHNOLOGIES LIMITEDInventors: Stephen MCMAHON, Damien O'ROURKE, Alberto ZAFFARONI, Redmond SHOULDICE, Tony FAGAN, Niall FOX, Niall O'MAHONY, Graeme LYON -

Publication number: 20210270935Abstract: Radio frequency motion sensors may be configured for operation in a common vicinity so as to reduce interference. In some versions, interference may be reduced by timing and/or frequency synchronization. In some versions, a master radio frequency motion sensor may transmit a first radio frequency (RF) signal. A slave radio frequency motion sensor may determine a second radio frequency signal which minimizes interference with the first RF frequency. In some versions, interference may be reduced with additional transmission adjustments such as pulse width reduction or frequency and/or timing dithering differences. In some versions, apparatus may be configured with multiple sensors in a configuration to emit the radio frequency signals in different directions to mitigate interference between emitted pulses from the radio frequency motion sensors.Type: ApplicationFiled: February 19, 2021Publication date: September 2, 2021Applicant: RESMED SENSOR TECHNOLOGIES LIMITEDInventors: Stephen MCMAHON, Przemyslaw SZKOT, Redmond SHOULDICE
