  • Calculating heart rate from acceleration signals containing cardiac activity signals
    Patent number: 9462956
    Abstract: A heart monitor includes a single chest accelerometer (210), an analog signal conditioning and sampling section (215) responsive to said accelerometer to produce a digital signal substantially representing acceleration, and a digital processor (220) operable to filter the acceleration signal into a signal affected by body motion and to cancel the body motion signal from the acceleration signal, thereby to produce an acceleration-based cardiac-related signal. Other processes and electronic systems are also disclosed.
    Type: Grant

  • MOTION/ACTIVITY, HEART-RATE AND RESPIRATION FROM A SINGLE CHEST-WORN SENSOR, CIRCUITS, DEVICES, PROCESSES AND SYSTEMS
    Publication number: 20110066041
    Abstract: A respiration monitoring device includes an accelerometer (210) for application to the chest, whereby acceleration is possible due to both non-respiratory body motion and respiration, and an electronic circuit (DSP) responsive to an acceleration signal from the accelerometer and operable to separate from the acceleration signal a heart signal, a respiration signal, and a substantially non-respiration body motion signal. Other devices, sensor articles, electronic circuit units, and processes are also disclosed.

  • ESTIMATION OF BLOOD FLOW AND HEMODYNAMIC PARAMETERS FROM A SINGLE CHEST-WORN SENSOR, AND OTHER CIRCUITS, DEVICES AND PROCESSES
    Publication number: 20110066042
    Abstract: An electronic monitoring device includes an electronic processor (520) having at least one signal input for body monitoring, and a memory (530) holding instructions for the electronic processor coupled to the electronic processor so that the electronic processor is operable to isolate a cardiac signal including cardiac pulses combined with other cardiac signal variations, and the electronic processor further operable to execute a filter (730) that separates a varying blood flow signal from the cardiac pulses and to output information (790) based on at least the varying blood flow signal. Other devices, sensor assemblies, electronic circuit units, and processes are also disclosed.
