A continuous wave of electromagnetic radiation can be transmitted toward one or more subjects and the Doppler-shifted received signals can be digitized and/or processed subsequently to extract information related to the cardiopulmonary motion in the one or more subjects. The extracted information can be used, for example, to determine apneic events and/or snoring events and/or to provide apnea or snoring therapy to subjects when used in conjunction with an apnea or snoring therapy device. In addition, methods of use are disclosed for sway cancellation, realization of cessation of breath, integration with multi-parameter patient monitoring systems, providing positive providing patient identification, or any combination thereof. ## Claims ### Claim 1 A system for detecting and treating snoring, said system comprising: a therapeutic device comprising a bio-feedback mechanism configured to stimulate a nerve in the subject's neck when a snoring event is detected. ### Claim 2 (depends on 1) The system of claim 1, wherein the therapeutic device comprises one or more selected from the group consisting of a microphone, acoustic stethoscope, and a transducer configured to utilize a snoring detection algorithm to determine the onset of a snoring event. ### Claim 3 (depends on 1) The system of claim 1, wherein the therapeutic device comprises a vibratory stimulus of increasing pulse width and pulse repetition rate. ### Claim 4 (depends on 1) The system of claim 1, wherein the therapeutic device comprises one or more selected from the group consisting of: a wrist worn device, pillow, mattress, clothing, and a skin-contact vibrating transducer configured to stimulate a nerve in the subject. ### Claim 5 (depends on 1) The system of claim 1, wherein the therapeutic device comprises a vibration transducer and/or electrodes configured to produce electrical signals to produce vibrations to stimulate the subject's neck muscles which will increase in sensation until the snoring event is stopped. ### Claim 6 (depends on 1) The system of claim 1, wherein the therapeutic device is configured to be coupled with a separate stand-alone device selected from the group consisting of: a sensor, smartphone, and a computer tablet. ### Claim 7 (depends on 1) The system of claim 1, wherein the therapeutic device is configured to be capacitively coupled to automatically power on when placed in use. ### Claim 8 (depends on 1) The system of claim 1, wherein the therapeutic device comprises a battery having an indicator of battery condition ### Claim 9 (depends on 1) The system of claim 1, wherein the therapeutic device comprises one or more selected from the group consisting of: storage of data, a web interface, a display, user interface and controls, a clock, recording hardware and software, and communications hardware and software. ### Claim 10 (depends on 1) The system of claim 1, wherein the therapeutic device comprises an embedded processor to process the signals and control the inter-sensor communications to relay data to the stand alone device. ### Claim 11 A method of treating apnea, comprising: detecting an apneic event of a patient via one or more sensors; sending information regarding the apneic event from the sensor to a sensor processing unit; sending a command from the sensor processing unit to a therapeutic device operably connected to an anatomical location of the patient, thereby activating the therapeutic device; and terminating the apneic event via the therapeutic device. ### Claim 12 (depends on 11) The method of claim 11, wherein the therapeutic device comprises a neck patch. ### Claim 13 (depends on 11) The method of claim 11, wherein terminating the apneic event comprises stimulating the hypoglossal nerve of the patient. ### Claim 14 (depends on 13) The method of claim 13, wherein stimulating the hypoglossal nerve is accomplished invasively. ### Claim 15 (depends on 13) The method of claim 13, wherein stimulating the hypoglossal nerve is accomplished non-invasively. ### Claim 16 (depends on 11) The method of claim 11, wherein the sensors are positioned in a location remote to the patient. ### Claim 17 (depends on 11) The method of claim 11, wherein the sensors are directly attached to the patient. ### Claim 18 A system for treating sleep apnea, the system comprising: a therapeutic device configured to perform at least one action related to a sleep apnea state of a patient, the therapeutic device comprising a bio-feedback mechanism that can stimulate an anatomical region of the patient when an apneic event is detected; and a communications module configured to communicate with therapeutic device, the communications module including one or more processors configured to extract information related to the apneic or snoring state of the patient and provide instructions to the therapeutic device. ### Claim 19 (depends on 18) The system of claim 18, wherein the processor is configured to predict apnea events.
