Embodiments of the present disclosure provide respiration monitoring systems and methods for using same. The respiration monitoring device can include a first accelerometer, a second accelerometer, at least one acoustic sensor, a memory comprising a lookup table, a real-time clock, and one or more instructions, and a processor for receiving one or more motion signals from each accelerometer and one or more sound signals from each acoustic sensor. The processor can correlate the one or more motion signals to a distance value, correlate the one or more sound signals to a sound value, filter the distance value and the sound value according to limitations stored in the lookup table, assign a time stamp to each filtered value, determine local maximums for the filtered motion values and local minimums for the filtered sound values, and match the local maximums to the local minimums to confirm a completed breath.

The multi-purpose video monitoring camera includes a microprocessor, a CMOS video camera, a thermographic video camera, a display unit and a mic array. The microprocessor includes a baby presence detection module, a warning module, a motion detection module, a breathing detection module, a hot air exhalation detection module, a chest movement detection module, a breathing sound detection module, a suffocation detection module, a temperature measurement module, a urination and defecation detection module, an air conditioning module and a baby growth rate module. By using inputs from both the CMOS video camera and the thermographic video camera, the accuracy of the baby presence detection module is improved.

This disclosure relates generally to bio-signal detection, and more particularly to method and system for non-contact bio-signal detection using ultrasound signals. In an embodiment, the method includes acquiring an in-phase I(t) baseband signal and a quadrature Q(t) baseband signal associated with an ultrasound signal directed from the sensor assembly towards the target. Magnitude and phase signals are calculated from the in-phase and quadrature baseband signals, and are filtered by passing through a band pass filter associated with a predefined frequency range to obtain filtered magnitude and phase signals. Fast Fourier Transformation (FFT) of the filtered magnitude and phase signals is performed to identify frequency of dominant peaks of spectrum of the magnitude and phase signals in the ultrasound signal. Value of the bio-signal associated with the target is determined based on weighted values of the frequency of the dominant peaks of the magnitude and phase signals.

A sensor for motion or gesture sensing may be configured to emit radio frequency signals such as for pulsed range gated sensing. The sensor may include a radio frequency transmitter configured to emit the pulses and a receiver configured to receive reflected ones of the emitted radio frequency signals. The received pulses may be processed by a motion channel and/or a gesture channel. The gesture channel may produce signals for further processing for identification of one or more different motion gestures such as by calculating and evaluating features from any of the amplitude, phase and frequency of the output signals of the gesture channel. The sensing apparatus may optionally serve as a monitor for evaluating user activities, such as by counting activities. The sensor may optionally serve as a user control interface for many different devices by generating control signal(s) based on identification of one or more different motion gestures.

A device for the treatment of snoring is provided. The device may include a flexible substrate configured for removable attachment to a subject's skin, a primary antenna disposed on the flexible substrate, an interface configured to receive a feedback signal that varies based upon a breathing pattern of the subject; and at least one processing device. The processing device may be configured to analyze the feedback signal and determine whether the subject is snoring based on the analysis of the feedback signal, and if snoring is detected, cause a hypoglossal nerve modulation control signal to be applied to the primary antenna in order to wirelessly transmit the hypoglossal nerve modulation control signal to a secondary antenna associated with an implant unit configured for location in a body of the subject.
