Abstract: The present invention relates to a device (100) for measuring a cycling cadence, a method (500) of operating a device (100) for measuring a cycling cadence, and a cycling cadence computer program. The device (100) comprises a motion sensor (such as, e.g., an accelerometer) for detecting a movement of the device (100) and for generating a motion signal (x, y, z) corresponding to the movement; a cadence determination unit (300) for determining cycling cadence based on the motion signal (x, y, z). The device (100) can be worn on the cyclist's wrist or arm (110). The motion sensor in the device is able to pick up the tiny movements of the arm or wrist that correspond to the cadence. Optionally, an algorithm is applied that can derive the cadence from a noisy signal.

Abstract: 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 (10); a motion signal providing unit (20); a parameter providing unit (30) for providing a subject specific parameter; a heart rate determination unit (40); a resting period determination unit (50); an abnormality determination unit (80) for determining an abnormality of the heart rate during the resting period; and an assessing unit (90) 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.

Abstract: An aerosol generation system has a light source arrangement which provides signals at first and second wavelengths, and the detected light signals are recorded. The detected signals are processed to derive at least a measure of the aerosol particle size. This can be used in combination with the other parameters which are conventionally measured, namely the aerosol density and flow velocity. Thus, optical measurement (possibly in combination with an air flow measurement) can be used to estimate the aerosol output rate as well as the particle size.

Abstract: The present invention relates to a device (10) for determining an arterial compliance of a subject (12). The device (10) comprises an inflatable cuff (14), a pressure sensor (18) which is configured to sense a pressure signal (52) that is indicative of a pressure within the cuff (14), a second sensor (20) which is at least partly integrated in the cuff (14) and configured to sense a second signal (56) that is responsive to expansions and contractions of the cuff (14) caused by a pulsating blood flow in an artery (50) of the subject (12), and a processing unit (22). The processing unit is configured to determine based on said part of the pressure signal (52) a pulse pressure of the subject (12), to determine based on said part of the second signal (56) an arterial volume change of the artery (50) of the subject (12) during at least one cardiac cycle, and to determine the arterial compliance of the subject (12) based on pulse pressure and the arterial volume change.
