Medical radar devices, including ultra-wideband (UWB) devices, for use in assisting and/or guiding cardiopulmonary resuscitation (CPR) by indicating one or more of: compression depth, compression frequency, and a return to spontaneous circulation. The devices and methods described herein may use reflected energy applied to a patient's chest to determine cardiac motion and/or chest compression and provide feedback to the person applying the CPR. In some variations the device is incorporated as a part of another resuscitation device, such as a defibrillator or automatic compression device.
One aspect of the invention relates to a system for providing therapy to a subject and/or promoting health effects in a subject. The system includes a body, and one or more conductive wires. The body includes two intertwined helically wound runners arranged in at least two complete revolutions per runner. The body is arranged in a toroidal shape having a centroid. The centroid is arranged at or near one or both of a subject and/or a body part of the subject. The first wire is wound spirally around the first runner. The first wire is conductive. Two leads of the first wire are configured to be electrically coupled with a current source.
One aspect of the invention relates to an electrical system for promoting growth of a plant and/or other organisms. The system includes a body, one or more conductive wires, and a current source. The body includes two intertwined helically wound runners arranged in at least two complete revolutions per runner. A first runner is coupled to a second runner by struts. The body has a periphery. The body is installed around or near a plant. The first wire is carried by the first runner. The first wire is conductive. The current source is arranged to electrically couple with two leads of the first wire causing a first current through the first wire along the first runner.
Described herein are fetal and/or maternal monitoring devices, systems and methods using UWB medical radar. These devices and systems may include a UWB sensor providing high-resolution and reliable simultaneous monitoring of multiple indicators of fetal and/or maternal health, such as fetal heart rate, fetal heart rate variability, fetal respiration, fetal gross body movement, maternal contractions, maternal heart rate, maternal respiration, and other derivative parameters during virtually all stages of pregnancy and during delivery. The sensor allows novel collection of physiological data using a single sensor or multiple sensors to develop individual and aggregate normal motion indices for use in determining when departure from normal motion index is indicative of fetal or maternal distress.

An electrical system having an underlying structure resembling the double helix most commonly associated with DNA may be used to produce useful electromagnetic fields for various applications. One aspect of the invention relates to an electrical system comprising a body and one or more conductive wires. The body may include two intertwined helically wound runners. A first runner is coupled to the second runner by struts. The body is arranged in a toroidal shape. The one or more conductive wires may be spirally wound around at least one runner of the body.
Ultra wideband patient monitoring systems, and particularly baby monitoring systems, adapted to prevent reflective loss between the antenna and the patient's body. The devices, systems and methods described herein may be used to efficiently couple UWB energy to a patient for patient monitoring. In particular, described herein are impedance transformer pads, mats and the like, upon which a patient may comfortably lie while being monitored via one or more UWB sensors (e.g., antenna); the impedance transformer pads help match the impedance and prevent reflective loss of UWB energy. Also described herein are bassinets, including NICU bassinets and baby monitors.

SYSTEM AND METHOD FOR NON-INVASIVE INSTANTANEOUS AND CONTINUOUS MEASUREMENT OF CARDIAC CHAMBER VOLUME
A system and method for non-invasive and continuous measurement of cardiac chamber volume and derivative parameters including stroke volume, cardiac output and ejection fraction comprising an ultrawideband radar system having a transmitting and receiving antenna for applying ultrawideband radio signals to a target area of a subject's anatomy wherein the receiving antenna collects and transmits signal returns from the target area which are then delivered to a data processing unit, such as an integrated processor or PDA, having software and hardware used to process the signal returns to produce a value for cardiac stroke volume and changes in cardiac stroke volume supporting multiple diagnostic requirements for emergency response and medical personnel whether located in the battlefield, at a disaster site or at a hospital or other treatment facility.
