Patent number: 11922915Abstract: An apparatus includes a sensor module configured for receiving sensed information indicative of a sensed signal. The sensed signal includes a source signal component and a source noise component. The apparatus also includes a reference module configured for reference information indicative of a reference signal. The reference signal also includes a reference noise component. The apparatus also includes a filter module configured as a fixed lag Kalman smoother. The filter module is configured for adaptively filtering the reference signal to generate an estimate of the source noise component. The apparatus also includes a processing module configured for calculating an output signal based on the sensed signal and the estimate of the source noise component. The apparatus also includes an interface module configured for transmitting an indication of the output signal. The filter module is further configured for, based on the output signal, tuning the Kalman smoother.Type: GrantFiled: May 5, 2020Date of Patent: March 5, 2024Assignee: Empatica SrlInventors: Ivan Cenci, Simone Tognetti

Publication number: 20230397833Abstract: An apparatus for measuring electrodermal activity can include a first electrode in contact with a first portion and a second electrode in contact with a second portion of a stratum corneum, and in electronic communication with the second electrode through the stratum corneum. A processing module is electrically coupled to the first electrode and the second electrode and is operable to (a) bias the first electrode at a first voltage V+ and the second electrode at a second voltage V? (b) measure a current flowing between the first electrode and the second electrode, the current corresponding to the conductance of the stratum corneum, (c) subtract a compensation current from the measured current (d) measure a resulting current producing an amplified output voltage (e) measure a conductance of the stratum corneum, and (f) adjust at least one of the first voltage, the second voltage and the compensation current to desaturate the output voltage.Type: ApplicationFiled: August 21, 2023Publication date: December 14, 2023Inventors: Simone TOGNETTI, Ivan CENCI, Daniele RESNATI, Maurizio GARBARINO, Matteo LAI

Publication number: 20230074365Abstract: A heart beat detection device comprises at least one optical reflection sensor to be positioned on the skin of a person. The sensor unit is provided with a light emitter and a corresponding light receiver which converts the light reflected by the skin into an electric signal and comprises electrically adjustable optical filters connected to the emitter, to the receiver or to both of them in order to select, upon operation, a desired light wavelength and perform processing of the signals thus obtained in order to reinforce the heart beat signal. A system with this device and a detection method are also described.Type: ApplicationFiled: June 13, 2022Publication date: March 9, 2023Applicant: Empatica SrlInventors: Simone TOGNETTI, Ivan CENCI, Daniele RESNATI, Maurizio GARBARINO, Matteo LAI

Publication number: 20230039091Abstract: Devices, systems, and methods herein relate to non-invasive patient monitoring for infection detection and infection resolution. These systems and methods may receive and measure patient biosignals to estimate an infection level of a patient. In some embodiments, a method may include the steps of receiving physiological data of a patient. An infection measure may be estimated based on the physiological data. An infection state of the patient may be detected based at least in part on the estimated infection measure.Type: ApplicationFiled: October 17, 2022Publication date: February 9, 2023Inventors: Simone TOGNETTI, Giulia REGALIA, Andrea MORTERA, Matteo LAI, Rosalind PICARD, Francesco ONORATI

Publication number: 20220265214Abstract: Embodiments described herein relate generally to a portable biometric monitoring device having a central pod, sensor electrodes, and a wearable band. The central pod can be removably coupled to the wearable band. The sensor electrodes can transfer data to an circuit on a printed circuit board (PCB) in the central pod. The circuit can be housed in the central pod and can be configured to process data transferred from the sensor electrodes. The central pod can be electrically coupled to the sensor electrodes via one or more conductive wires while the wearable band is coupled to the central pod. In some embodiments, the central pod can be electronically isolated from the sensor electrodes when the wearable band is not coupled to the central pod. In some embodiments, the one or more conductive wires are substantially encased in the wearable band.Type: ApplicationFiled: May 13, 2022Publication date: August 25, 2022Inventors: Parth JARIWALA, Matteo LAI, Simone TOGNETTI, Daniele RESNATI, Nicolo BONACINA, Chris LOUGHNANE, Ivan CENCI
