Embodiments provide physiological measurement systems, devices and methods for cardiovascular intensity measurement. In an aspect, a wearable device receives a time series of heart rate data for a user. The time series of heart rate data can be weighted and summed according to a weighting scheme. The weighted and summed time series of heart rate data can be used to generate an intensity score indicating the cardiovascular intensities experienced by the user during a desired period of time.

A compact integrated patch may be used to collect physiological data. The patch may be wireless. The patch may be utilized in everyday life as well as in clinical environments. Data acquired by the patch and/or external devices may be interpreted and/or be utilized by healthcare professionals and/or computer algorithms (e.g., third party applications). Data acquired by the patch may be interpreted and be presented for viewing to healthcare professionals and/or ordinary users.

Disclosed is a wearable device for being worn on the torso of a user, at least one of limbs of the user or a combination thereof. The wearable device comprises a wearable body and at least one positioning unit , wherein the wearable body has at least two fixing parts respectively fixed on at least two adjacent movable joints of the user, so that the wearable body is fitted to the torso, the at least one of the limbs or the combination thereof; the wearable body forms a positioning region between the fixing parts ; a portion, between the two adjacent movable joints, of the torso, the at least one of the limbs or the combination thereof located is located in the positioning region; and the positioning unit is configured in the positioning region to correspond to a specific position of the user.

A mobile device is provided. The mobile device includes a display, a front camera provided to face in a forward direction of the display, a touch sensor provided at a front side of the display, and a processor configured to acquire a photoplethysmography (PPG) signal from an image of a finger captured by the front camera in a PPG measurement mode, and output guide information that guides at least one of a position of the finger or a contact pressure with which the finger presses the front camera based on at least one of an output of the touch sensor or the image of the finger.

A method includes placing a set of electrodes on a body surface of a patient's body. The method also includes digitizing locations for the electrodes across the body surface based on one or more image frames using range imaging and/or monoscopic imaging. The method also includes estimating locations for hidden ones of the electrodes on the body surface not visible during the range imaging and/or monoscopic imaging. The method also includes registering the location for the electrodes on the body surface with predetermined geometry information that includes the body surface and an anatomical envelope within the patient's body. The method also includes storing geometry data in non-transitory memory based on the registration to define spatial relationships between the electrodes and the anatomical envelope.

Methods of measuring a physical or physiological parameter using an integrated adhesive sensor array including a sensor hub and a detachable sensor pod are presented. In one example, a method comprises: establishing a first communication link between the sensor hub and a wireless receiver; attaching at least the sensor hub directly to a body; establishing a second communication link between the detachable sensor pod and the sensor hub; sensing a physical or physiological parameter by the detachable sensor pod; transmitting sensor data of the physical or physiological parameter from the detachable sensor pod to the sensor hub via the second communication link; and transmitting the sensor data from the sensor hub to the wireless receiver via the first communication link.

A plurality of devices that provide examination/diagnosis and/or treatment benefits to a patient are presented. The device including a plurality of light sources that provide for the emission of light in a plurality of wavelength ranges, wherein the plurality of light sources are activated by a sensor, configured to determine a proximity of the device to a patient, to control an application of a voltage to selected one of the plurality of light sources for a predetermined time period.

A portable device for measuring an electrocardiogram (ECG) of a user. The portable device includes a first ECG sensor that is configured to touch a body of the user, and a processor. The processor is configured to receive a first ECG measurement at a first location on the body of the user, where the first ECG sensor is placed at the first location of the body; identify a first region of the heart of the user based on the first location; direct the user to move the portable device to a second location on the body of the user; receive a second ECG measurement at the second location on the body; and identify a second region of the heart of the user based on the second location.

A mobile healthcare device and method of operating the same are provided. The method includes setting a mode of the mobile healthcare device to a measurement mode, displaying a screen for guiding a user to maintain a predetermined position during the measurement mode, and, in response to a predetermined amount of time passing from a time at which the screen begins to be displayed, obtaining state information of the user based on bio information of the user, the bio information being received from a sensor.

A blood pressure analyzing apparatus includes: a blood pressure variation determiner determining whether first blood pressure information varies a threshold or more from second blood pressure information or not, the first blood pressure information corresponding to an arbitrary beat, the second blood pressure information corresponding to a previous beat to the arbitrary beat; a blood pressure variation cause determiner determining whether a blood pressure variation is caused by the move of the wrist or by another reason than the move of the wrist, based on, wrist move information detected in a detection period of a pulse wave serving as a calculation source of the first blood pressure information, when it is determined that the first blood pressure information varies the threshold or more from the second blood pressure information; and a recording controller recording a determination result and the first blood pressure information in association with each other.
