Classification: CPC A | IPC A

Claim 13:
14. A non-transitory computer readable medium storing instructions for reducing motion artefacts in a detection of at least one of pulse or pulse-related information of a patient that, wherein when executed by the one or more computer processors, the instructions cause the one or more computer processors to:
receive an accelerometer signal acquired by an array of accelerometer sensors arranged at skin of the patient;
wherein the accelerometer sensors are configured to directly contact the skin via an adhesive layer or a fastening strap;
where the accelerometer sensors are mechanically decoupled in at least one direction;
measure a skin surface acceleration with the accelerometer sensors;
combine signals from the array of accelerometer sensors to obtain the accelerometer signal from the skin surface acceleration;
receive a pulse-related signal of the patient from a pulse signal sensor;
receive patient information from a patient information source;
generate a template accelerometer signal that models accelerometer-based pulse palpation using the pulse-related signal as a reference signal and further using the patient information and context information indicating context of the acquisition of the accelerometer signal;
extract one or more features from the accelerometer signal by comparing the accelerometer signal to the generated template accelerometer signal;
determine the pulse and pulse strength of the patient from the one or more extracted features;
and display on the display a presence of the pulse and the pulse strength.
