A non-contact respiratory monitoring system comprises a magnetic microwire sensor coil that detects magnetic field changes due to motion of a magnet attached to a patient's chest. Field lines emanating from the magnet are parallel to a circumferential loop area of the coil and the coil is positioned at a distance to magnetically couple to the magnet. Impedance in the coil changes when the distance of the magnet to the coil changes due to the patient's breathing. An alternating voltage across coil is modified by the change in impedance. An impedance analyzer coupled to the coil applies the alternating voltage and measures the impedance changes. A computer system controls operation of impedance analyzer, receives respiratory monitoring information based on the coil's impedance changes from the impedance analyzer, and generates a graphical display of the respiratory monitoring information.

A garment (e.g., a shirt) for monitoring biometric properties of the wearer of the garment is disclosed. The garment may include sensors for monitoring or assessing the vital signs and body position of the wearer. A processor associated with the garment may provide an output indicative of an assessed condition of the wearer based on the assessed vital signs and the assessed body position of the wearer of the fabric. The garment may include an injector assembly that is used to administer a drug injection to the wearer when the assessed condition indicates that the wearer is in an alert condition.

The present invention relates to an integrated sleep diagnosis and treatment device, and more particularly to an integrated apnea diagnosis and treatment device. The present invention additionally relates to methods of sleep diagnosis and treatment. The sleep disorder treatment system of the present invention can use a diagnosis device to perform various forms of analysis to determine or diagnose a subject's sleeping disorder or symptoms of a subject's sleep disorder, and using this analysis or diagnosis can with or in some embodiments without human intervention treat the subject either physically or chemically to improve the sleeping disorder or the symptoms of the sleeping disorder. The diagnostic part of the system can use many different types of sensors and methods for diagnosing the severity of the symptoms of or the sleep disorder itself. The treatment part of the system can use a device to physically or chemically treat the subject's symptoms or sleep disorder itself.

Embodiments of the present invention are related to a method and device for the determination and calculation of the depth of chest compressions during the administration of cardiopulmonary resuscitation (CPR). Embodiments use an optical sensor to monitor the distance that a victim's chest is displaced during each compression throughout the administration of CPR. The optical sensor is most commonly an image sensor such as a CMOS or CCD sensor, and more specifically a CMOS image sensor capable of three-dimensional imaging based on the time-of-flight principle. An infrared emitter may illuminate the victim's body and any visible piece of ground beside the victim. As the infrared light interacts with any surfaces it encounters, it is reflected and returns to the image sensor where the time of flight of the infrared light is calculated for every pixel in the image sensor. The distance data is used to gauge the effective displacement of the victim's chest. The optical sensors can be used to visualize the size of a patient and immediately gauge the body type and instruct the user accordingly. Furthermore, optical measurement techniques can be used to accurately measure chest rise during artificial respiration and ensure that proper ventilation is being administered in between compressions. In addition, optical measurements of the chest of the victim and the hands of the rescuer can be used to help ensure that the rescuer has positioned his or her hands in the anatomically correct location for effective CPR.
