The present invention relates to a device, system and method for automatic and unobtrusive caloric intake detection. The device comprises a respiration input for obtaining a respiration signal indicating the subject's respiration, and an analysis unit for analyzing the obtained respiration signal in the frequency domain by determining one or more respiration signal features from the obtained respiration signal in the frequency domain related to changes in oxidation and by detecting changes of the one or more determined respiration signal features to detect periods of caloric intake by the subject.

The present invention relates to distinguishing different sedentary states of a subject. A sedentary state can refer to standing, sitting and/or lying. An apparatus for determining a sedentary state of a subject is presented that comprises a sensor interface for obtaining a movement signal indicative of a movement of the subject; an extraction unit for extracting a signal feature indicative of postural control oscillations of the subject from the movement signal, wherein the signal feature indicative of postural control oscillations is indicative of center of mass motion oscillations for preventing the subject from falling; and a classifier for classifying a sedentary state of the subject based on the signal feature indicative of postural control oscillations of the subject. Further, a corresponding method, computer program and system are presented.

The present invention relates to an assessing system, an assessing method and a computer program for assessing a heart rate of a subject. It finds application in categorizing a physiological response as a condition, in particular in the diagnosis of pathological tachycardia and bradycardia. The assessing system comprises a photoplethysmography (PPG) signal providing unit (); a motion signal providing unit (); a parameter providing unit () for providing a subject specific parameter; a heart rate determination unit (); a resting period determination unit (); an abnormality determination unit () for determining an abnormality of the heart rate during the resting period; and an assessing unit () for assessing the determined abnormality based on the subject specific parameter. The invention provides a system and a method, which allow for a more reliable assessment of a heart rate of a subject based on a PPG signal of the subject.

Presented are concepts for monitoring the liquid or food consumption of a person. Once such concept employs the step of detecting a change in weight of the person resultant from usage of a toilet. A value representative of at least one of liquid consumption and food consumption of the person may then be determined based on the detected change in weight of the person.

Monitoring liquid and/or food consumption of a person

There is provided an apparatus for monitoring the ingestion of food and/or drink by a subject, the apparatus comprising a control unit that comprises a first obtaining module configured to obtain measurements of one or more physiological characteristics of the subject; a second obtaining module configured to obtain measurements of eddy currents generated in the body of the subject by an externally-applied magnetic field; a setting module configured to set a respective cut-off frequency for one or more filtering stages based on a respective frequency for each of said one or more physiological characteristics; a filtering module configured to filter the measurements of eddy currents using the one or more filtering stages to remove signal components due to the one or more physiological characteristics; and a processing module configured to process the filtered measurements to determine whether food and/or drink is present in the stomach of the subject.

Methods and systems for assessing cardio-respiratory fitness (CRF) with the use of body motion data is disclosed. Specific measurements of body movement (for example, motion amplitude or velocity, or distance covered during repetitive displacement) are dependent on a user's fitness level. Embodiments prompt the user to execute a simple set of periodic movements which can be used to estimate cardiovascular function (e.g., VO). Body motion data, such as activity count, accelerometer signals, or cadence of motion, is captured and analyzed to estimate the user's fitness. The combination of body motion data with various physical measurements (e.g. body weight, height, BMI) permits the method to predict the user's VOor similar physical fitness parameters.

Various embodiments relate to methods, devices, and systems for ascertaining a sedentary body posture of a subject including: determining if the subject is in a sedentary state when the subject is sedentary for a pre-determined time; receiving a heart rate signal for least one heart rate feature when the subject is in the sedentary state; deriving at least one heart rate feature value when the subject is in the sedentary state further including filtering an arousal value from the received heart rate signal, so as to reduce an influence of the arousal on the determination of the sedentary posture; and determining the sedentary body posture of the subject based on a comparison between the derived at least one heart rate feature value and a pre-determined range associated with the corresponding at least one heart rate feature, wherein for each sedentary body posture, a pre-determined range is stored.

The present invention relates to device, system and method for counting the number of cycles of a periodic movement of a subject, e.g. for step counting of a person. To enable more precisely counting the number of cycles of a periodic movement of a subject based on discontinuous accelerometer data the proposed device comprises an input unit () for receiving discontinuous accelerometer data over time indicating movement of at least a body part of the subject, a classifier () for classifying the movement of the subject into one of several movement classes based on said discontinuous accelerometer data, each movement class being related to a different range of speed of a periodic movement, a storage () for storing a table including for each movement class a periodicity value per time unit, and a movement calculation unit () for calculating the number of cycles of the periodic movement of the subject per time unit, for a predetermined time or continuously over time by use of the periodicity of the movement class, into which the movement has been classified.
