摘要： A wearable health device system includes a housing configured to be worn by a subject,and a sensor assembly with at least two accelerometers which sense acceleration along non-parallel axes. A processor operably connected to the sensor assembly and a memory executes program instructions in the memory to obtain SCG template data from the accelerometers and divide the obtained SCG template data into at least one cardiac cycle segment. The cardiac cycle segment is used to generate an SCG acceleration template which is in turn used to generate an SCG rotation matrix. SCG acceleration data is then obtained from the accelerometers and normalized by applying thegenerated SCG rotation matrix to theobtained SCG acceleration.

摘要： A blood pressure and cardiac monitoring system includes a sensing assembly, which comprises a first sensor (102a) located at a first axis of a target generating a first time-dependent motion waveform (302) representative of one or more contractile properties of the target's heart and a second sensor (102b) located at a second axis of the target generating a second time dependent motion waveform (304). The processor is configured to determine a first time difference between a vital sign present in the first time dependent motion waveform and the second time dependent motion waveform. A third sensor (102c) located either at the first or the second axis of the target generates a third time dependent waveform (300) representative of the electrical potential due to the depolarization of heart muscle. At least one of the sensors may be configured to either remove motion artifacts (as a reference sensor) or detect attributes from the environment for providing context awareness information.
