Abstract

A method based on pulse wave analysis for monitoring cardiovascular vital signs, including: measuring a photoplethysmography (PPG) signal during a measurement time period such as to obtain a time series of PPG pulses; and during the measurement time period, identifying individual PPG pulses in the PPG signal, each PPG pulse corresponding to a PPG pulse cycle. For each PPG pulse, the method uses a pulse-wave analysis technique to determine, within the pulse cycle, at least one of: a time-related feature comprising a time duration and a normalized amplitude-related pulse-related feature and a SNR-related pulse-related. For each PPG pulse, a machine learning model is used in combination with the determined time-related, normalized amplitude-related and SNR-related features, to classify each PPG pulse in the pre-processed PPG signal as “normal”, “pathological” or “non-physiological” such as to output a time series of pulse classes.

The escapement mechanism (30) is connected to the point of attachment (12) of the spiral spring by a chassis (40) pivoted about the axis (A) of the balance. An outer end (12) of the spiral spring (10) is attached to this transverse pert (40) at a location located on one side of the balance axis (A). The chassis (40) includes two branches extending on either side of the axis of the balance (20) and forming a rotary plate whose axis of rotation is coincident with the axis of oscillation of the balance (20). The escapement mechanism (30) is located on the other side of the balance axis (A) and acts on the pivoted chassis (40) so as to free its rotation and thus make the attached end (12) of the spiral spring rotate.

Abstract

A security feature has a plurality of luminescent surface elements, wherein luminescence lifetime varies between the surface elements. In order to verify the security feature, a lock-in imager is used. The security feature is illuminated with excitation light, which is intensity-modulated with a modulation frequency. The luminescent light emitted by the security feature is detected synchronously with the modulation frequency in a plurality of pixels. This is used to determine a measure of a phase shift between the excitation light and the luminescent light in different pixels. The security feature is verified taking account of the measure of the phase shift in different pixels.
