A continuous, non-invasive fetal heart rate measurement is produced using one or more ultrasonic transducer array patches that are adhered or attached to the mother. Each ultrasound transducer array is operated in an autonomous mode by a digital signal processor to obtain data from which fetal heart rate information can be derived. Each ultrasonic transducer array patch comprises a multiplicity of subelements that are switchably reconfigurable to form elements having different shapes, e.g., annular rings. Each subelement comprises a plurality of interconnected cMUT cells that are not switchably disconnectable. The use of cMUT patches will provide the ability to interrogate a three-dimensional space electronically (i.e. without mechanical beam steering) with ultrasound, using a transducer device that is thin and lightweight enough to stick to the patient's skin like an EKG electrode. The ultrasound device can track the fetal heart in three-dimensional space as it moves due to the mother's motion or the motion of the unborn child within the womb.

Exercise systems and methods are provided that create and run exercise programs that are custom tailored to individual users. An exercise program for a specific user is based upon the user's average work heart rate and recovery heart rate. The exercise programs may include a series of workouts for the user to perform. Each workout requires the user to exercise at various intensity levels so that the user's heart rate moves between different predetermined target heart rate zones. The target heart rate zones are calculated from data relating to the user's average work heart rate and recovery heart rate. As the user's fitness level changes, the user's average work heart rate and recovery heart rate also change. Creation of new exercise programs uses the most current heart rate data to calculate the target heart rate zones, thereby continuously tailoring the exercise programs to the user.

The invention relates to a system and a method for the prediction of epileptic seizures by continuous measurement of at least one signal on the body of a user. A sensor unit measures the heart rate continuously and is connected to a processor unit.

An analysis unit in the processor analyzes the verified measurements to determine whether a preictal phase is present or not. The processor comprises a summation unit, which continuously determines the value of an indication signal on the basis of the signal from the analysis unit. The signal indicates the probability of an imminent epileptic seizure. The value of the indication signal may be determined on the basis of at least two values of the signal from the analysis unit. An alarm unit connected to the processor unit generates one or more alarms, if the indication signal exceeds one or more alarm levels.
