Publication number: 20210369209Abstract: 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.Type: ApplicationFiled: June 2, 2021Publication date: December 2, 2021Inventors: Fabian Braun, Martin Proença, Jérôme Van Zaen, Philippe Renevey, Mathieu Lemay

Publication number: 20200359961Abstract: Devices and methods for detecting meal intake are disclosed herein. In some embodiments, one or more sensors can be used to detect or monitor physiological parameters of a user (e.g., heart rate, body movements, temperature, pH, impedance, gastric stretch, sound emissions, and the like). The outputs of the sensors can be received by a computer system configured to analyze the sensor data and make a determination as to whether meal intake has occurred or is presently occurring. The computer system's determination can be used to trigger, modulate, or otherwise control one or more therapeutic devices. Other types of devices can also be controlled using this determination, such as monitoring or logging devices.Type: ApplicationFiled: August 5, 2020Publication date: November 19, 2020Inventors: Adam Dunki-Jacobs, Jason L.

Patent number: 10525613Abstract: A process and associated system for creating color effects in extrudable material, such as plastic and metal for example, are presented. Flows of first and second viscous materials of respective colors are provided and then combined in a predetermined pattern to form a stream of combined viscous material. In a first aspect, the flow rate of the first viscous material is caused to vary over time in order to vary an amount of the first viscous material in the stream. In a second aspect, which may be used alone or in combination with the first aspect, the first and second viscous materials have distinct viscosities to reduce an amount of color blending between the first color and the second color in the stream of combined viscous material.Type: GrantFiled: December 23, 2015Date of Patent: January 7, 2020Assignee: Pelican International Inc.Inventors: Mathieu Lemay, Steve Jalbert

Publication number: 20080282079Abstract: The present disclosure provides a system and method for ad-hoc processing of cryptographically-encoded data. In one embodiment, a recipient receives a cryptographically-encoded email and proceeds to contact a processing server to decrypt said cryptographically-encoded email. The recipient may interact with the server either by copying-and-pasting the content of the cryptographically-encoded email to a web interface provided by the processing server or by forwarding it to the processing server using his existing email software. In the case of the forward, the processing server sends yet another email back to the recipient containing a URL to a web interface for continuing to interact with the processing server in order to decrypt the cryptographically-encoded email. Through its web interface, the processing server guides the recipient through the steps required to view a decrypted version of the cryptographically-encoded email.Type: ApplicationFiled: May 2, 2008Publication date: November 13, 2008Inventors: Karim Yaghmour, Mathieu Lemay
