Cardiac pulse wave retrieval from an electrical signal
Summary
USPTO granted Patent US12588824B2 to Onera Technologies B.V. for a method and system of determining cardiac pulse wave signals by processing ECG and electrical signals. The patent includes 20 claims and names inventors Jantina Catharina de Vries and Hartmut Schneider.
What changed
USPTO granted Patent US12588824B2 to Onera Technologies B.V. on March 31, 2026, covering methods for extracting pulse wave signals from electrical signals using ECG data as a reference. The system involves identifying points of interest in ECG signals, determining specific points in electrical signals, generating a cleaned signal, and deriving pulse wave signals through signal subtraction. The patent application (17616073) was filed July 15, 2020.
Patent holders should review this grant to assess potential implications for competing cardiac monitoring technologies and consider whether their own IP portfolios require protection strategies. Healthcare technology companies developing similar pulse wave or ECG-based cardiac monitoring systems should evaluate freedom-to-operate considerations.

Abstract
The present disclosure relates to a method and a system for determining a pulse wave signal (PWS) of a subject. The method (M100) comprises: a step M101) of providing an electrocardiographic (ECG) signal (S2) of a subject (200); a step (M102) of providing an electrical signal (S3) of the subject (200); a step (M103) of determining a collection of points of interest (S2x) in the ECG signal (S2); a step (M104) of determining a collection of specific points (S3x1, S3x2) using the collection of points of interest (S2x); a step (M105) of determining a cleaned electrical signal (S4) based on the collection of specific points (S3x1, S3x2); a step (M106) of determining a pulse wave signal (PWS) by subtracting the cleaned electrical signal (S4) from the electrical signal (S3).
