Abstract:
A method for retrieving operating data from a measuring device measuring brain waves includes: a measurement signal acquisition on the measuring device; a first test step determining whether a primary connection can be established between the measuring device and a data processing server; if so, a step of primary transfer of operating data from the measuring device to the server; otherwise, a second test step for determining whether a secondary connection can be established between the measuring device and a portable relay device; if a secondary connection can be established, a step of secondary transfer of operating data from the measuring device to the portable relay device; a third test step determining whether a tertiary connection can be established between the portable relay device and the server; if so, a tertiary transfer step of the operating data of the portable relay device to the server.
Abstract:
A method and system for personalized acoustic brain wave stimulation of a person. The system comprises an acoustic stimulation device and a remote server. The device comprises a memory able to store operating parameters, acquisition element of a measured signal analysis element in order to assess whether the person is in a state susceptible to stimulation and emission element designed for emitting an acoustic signal. The acquisition element, analysis element and/or emission element operate depending on operating parameters. The device and the remote server comprise means of data transmission for transmitting operating data from the device to the server and transmitting second operating parameters from the server to the device. The remote server comprises means of processing operating data for determining second operating parameters.
Abstract:
The invention relates to a self-contained device (1) for stimulating slow brain waves, capable of being worn by a person (P), in particular during a period of time when said person is sleeping. The device (1) comprises a supporting element (2), capable of surrounding the head of a person, and on which electrodes (3) are mounted in contact with the person in order to acquire a measurement signal that represents a physiological electrical signal of the person; an acoustic transducer (4) for emitting an acoustic signal (A) stimulating the inner ear of the person; and on-board conditioning and control electronics (5) for, in flexible real time, receiving the measurement signal and controlling the emission of an acoustic signal (A) synchronised with a predefined slow brain wave time pattern.
Abstract:
An electrode for acquiring electroencephalogram signals of a user includes a base and a plurality of legs extending from the base at first extremity. The legs include a second extremity covered with an electrically conductive material. The second extremity includes a smaller cross-section than the first extremity of the legs so the legs can penetrate through hair of the user. The legs elastically flex such that, when the electrode is applied on a user's head, the electrically conductive material of the second extremity contacts a scalp of the user, wherein the base is of cuboid shape having two side faces, the legs being directly attached to the side faces of the base, the legs being symmetrically attached to the base with respect to a longitudinal axis and the legs attached to a side face of the base facing the legs attached to the other side face of the base.
Abstract:
The method for commanding the production of an acoustic waveform based on a physiological control signal, includes: one provides sampled sound data including S sound samples stored on a data carrier; repeatedly, for n successive respective time intervals [tn; tn+1[ between an initial time ta and a final time tb: one provides a physiological control signal phi(t) as a function of time, during the current time interval [tn; tn+1[; a rate determination module of a processor determines a rate rn of samples to be played during that time interval based on a value phi (tn) of the physiological control signal at time tn; a command module of the processor commands the play of a part of the acoustic waveform from the sampled sound data as a function of the determined rate rn of samples.

Abstract:
The mechanism is arranged in a clock driven either by a main spring or a battery, and comprises a manually rotatable switch cam, of insulating material, having three stepped portions of progressively increasing height on its periphery and three pits or dents in its periphery, each related to one of the stepped portions. The timing switch includes two relatively fixed contact springs and a third intermediate and movable contact spring, each of the relatively fixed springs having a contact thereon engagable with a respective contact on the intermediate spring. A spring engagable in the notches releasably retains the switch cam in a selected operated position. A flexible contact arm connected to one of the two relatively fixed contacts engages an annular contact on an unlocking wheel, and a projecting contact finger is secured to an hour wheel of the clock. The annular contact has a radially inwardly projecting extension which is engagable by the contact finger on the hour wheel. The intermediate contact is normally engaged with that fixed contact which is not connected to the contact arm engaging the annular or ring contact. In another embodiment the intermediate contact and one of the fixed contacts are extended for cooperation with another cam forming part of a mechanism whereby a transistor radio, when turned on, may be automatically turned off by the clock after a preset time interval.
