Abstract: A photoplethysmography (PPG) sensor configured to be worn on a user's body, the PPG sensor comprising: a sensing portion comprising an optical emitter configured to emit an emitted light toward the user's body, and an optical detector for detecting a detector light reflected or scattered from the tissue, such as to provide a PPG signal; and an interfacing portion comprised between the sensing portion and the user's body, the interfacing portion comprising a transparent interface element through which the emitted light is transmitted when travelling from the optical emitter toward the body, and through which the detector light is transmitted when travelling from the body to the optical detector, wherein the transparent interface element has an interface transmittance; the transparent interface element comprising an antireflective interface being configured such that an antireflective interface transmittance of the transparent interface element comprising the antireflective interface is larger than the interfac

Abstract: System for determining a blood pressure (BP) of users, comprising: for each user, a signal module configured to cooperate with a wearable device destined to be worn on a wrist of the user and comprising a pulsatility sensing unit; the signal module comprising a controlling module for controlling the pulsatility sensing unit to measure a plurality of pulsatility signals at the user's wrist; a processing module for processing the pulsatility signals to obtain pulsatility signal data; and a communication module for remotely transmitting said pulsatility signal data; the system further comprising an external service module including a database storage system for storing in a database the transmitted pulsatility signal data for each user; and a calculating module configured for calculating a BP value for each user, based on the pulsatility signal data stored in the database.

Abstract: The invention is directed to techniques for stimulating a colon of a patient to relieve chronic constipation. Specifically, a colon stimulation system applies one or more electrical stimuli to the colon of the patient in order to induce peristaltic activity in the colon to relieve chronic constipation. In accordance with the invention, the colon stimulation system induces peristaltic activity in the colon by applying an electrical stimulus to the colon to cause a portion of the colon to contract to a contracted state and removing the electrical stimulus to cause the colon to relax. While in the contracted state, the colon is substantially fully contracted.
