Patent number: 10610162Abstract: A heart-rate associated with a heartbeat signal is determined. A transform is selected based on the determined heart-rate associated with the heartbeat signal and a reference heart-rate associated with a dictionary of a sparse approximation model. The transform is selected independent of other factors associated with generation of the heartbeat signal. The selected transform is applied to the dictionary of the sparse approximation model, generating an adjusted dictionary of the sparse approximation model. Anomalous heartbeats in the heartbeat signal are detected using the adjusted dictionary of the sparse approximation model.Type: GrantFiled: September 5, 2017Date of Patent: April 7, 2020Assignee: STMICROELECTRONICS S.R.L.Inventors: Beatrice Rossi, Pasqualina Fragneto, Diego Carrera, Giacomo Boracchi, Daniele Zambon

Patent number: 10595788Abstract: A heartrate monitor detects heartbeats in a test signal. A local heartrate and an energy of acceleration are associated with the detected heartbeats. Detected heartbeats are included or excluded from a test set of heartbeats based on the local heartrate and energy of acceleration associated with the respective heartbeats. Anomalous heartbeats in the test set of heartbeats are detected using a sparse approximation model. The heartrate monitor may detect heartbeats in a training heartbeat signal. A reference heart rate and an energy of acceleration are associated with detected beats of the training heartbeat signal and selectively included in a set of training data based on the heart rate and energy of acceleration associated with the detected beat in the training heartbeat signal. A dictionary of the sparse representation model may be generated using the set of training data.Type: GrantFiled: May 31, 2016Date of Patent: March 24, 2020Assignee: STMICROELECTRONICS S.R.L.Inventors: Beatrice Rossi, Pasqualina Fragneto, Daniele Zambon, Diego Carrera, Giacomo Boracchi
