Abstract: A thermal diode device including an electronic unit to be cooled, a heat-dissipation medium, a temperature sensor for measuring the temperature of the heat-dissipation medium, and an actuator configured to thermally disconnect the electronic unit from the heat-dissipation medium if the temperature of the heat-dissipation medium is higher than a reference temperature, so as to inhibit any heat transfer between the heat-dissipation medium and the electronic unit, and to thermally connect the electronic unit to the heat-dissipation medium if the temperature of the heat-dissipation medium is lower than the reference temperature, so as to allow a conductive heat transfer between the electronic unit and the heat-dissipation medium.

Abstract: A method for allowing at least one passenger, wearing a personal listening device broadcasting an audio signal, to hear an oral message uttered by an authorized person in a transport vehicle, the method including detecting, recording and encoding said oral message as a voice signal, configuring a “payload signal to noise” ratio in the perceived audio signal, in which the payload signal consists of the oral message and in which the noise consists of the audio signal and stray noise, at a value greater than a predetermined threshold, and broadcasting the voice signal on a wireless communication network, to a mobile terminal connected to the personal listening device or directly to the personal listening device in order to broadcast it to the at least one passenger.

Abstract: A method for managing the electrical consumption of an on-board device in a vehicle including an electric power supply battery, the device having a virtual battery, corresponding to a maximum energy quota available to keep the device active, the method includes determining a level of charge of the virtual battery depending on the level of charge of the electric power supply battery, and, in a discharge situation of the electric power supply battery: determining a probable duration of the discharge situation, calculating a score for the benefit of keeping the device active depending on at least one parameter of the vehicle and/or of the user, and, determining an instruction to keep the device active or to stop the device depending on the score and on the probable duration of the discharge situation, and stopping the on-board device if the stop instruction is determined.

Abstract: A method, a management system and an application for coordinating the transmission of a geolocated instruction from a roaming element (12) to a multimedia element (4) on board a vehicle. To do this, the method includes notably transmitting an anticipation instruction (24), as a function of a latency time for the restitution of the geolocated instruction by the multimedia element (4) and transmitting this anticipation instruction (24) to the roaming element (12) so as to coordinate the transmission of this geolocated instruction.

Abstract: An apparatus for guiding a vehicle allowing a route sweep is disclosed. The apparatus includes a display which shows a portion of a map. The user may move the map on the display from a start point to a finish point. This movement is termed a route sweep. To carry out a route sweep allowing a user to take cognizance of a route proposed by the apparatus, the maximum rate of sweep of the map on a display screen, the so-called cruising rate (L), desirable to obtain a short sweep time, is first calculated. Then starting from a specified scale (R.S.), the map is moved at an increasing rate in such a way as to arrive at the cruising rate (L) after a predetermined time. Simultaneously, the scale (chain-dotted curve) is reduced so as to arrive after the same time at a scale which is compatible with the cruising rate.

Abstract: A telephone set includes transmitting parts (M, 131, 132) which enable a speaker to send a voice message to a correspondent, receiving parts (E, 132, 133) which enable the speaker to receive a return voice message coming from the correspondent and circuitry (11, 12, 16) which permit the sound volume of the return voice message supplied to the speaker via the receiving means to be adapted as a function of a sound volume of ambient noise locally surrounding the speaker. The adaptation circuitry includes a fuzzy logic section (14, 15) which receives measurements of a breathing noise caused by the speaker and measurements of the speech signal and of the ambient noise, and produces a control signal (COM) for monitoring the sound volume of the return voice message sent to the speaker.

Abstract: An electrostatic-shutter image tube (10) has a shutter electrode (17) disposed between an electron source (12) and a focusing and accelerating electrode (13). An electron flow is propagated through a network of equipotential lines to form an image on a target (14). The shutter electrode (17) is annular and conforms with an equipotential line. Deflection electrodes (20a,20b) and an image sequencer (21) make it possible to influence the position of a sequence of small images on the target (14) where they are temporarily stored.

Abstract: A device for automatic sound control includes a detection circuit for supplying objective sound and/or noise measurements relating to an ambient sound volume, and a fuzzy logic control circuit for adjusting, in response to the ambient noise measurements sound transmission characteristics supplied by an acoustic device. The device includes a fuzzy logic conversion circuit which is arranged between the detection circuit and the control circuit and transforms the objective ambient noise measurements into subjective ambient noise measurements for performing said settings. The device can learn the personal settings defined by a listener. The device can also detect speech and perform specific settings.
