Abstract: The invention relates to the use of the modulation of an audio and/or visual signal by a variation in the impedance of at least one contact with the skin of at least one user, for the maintenance and/or development of the user's physical and/or mental abilities. The invention comprises the use of a device (100) for controlling the delivery of a medium, said device comprising: a first skin electrode (105) configured to generate electric waves, positioned against the skin of a first user; a second skin electrode (110) configured to capture electric waves, positioned against the skin of a second user, where the second user can be the first user; a detector (115) for detecting the value of an impedance parameter of the junction connecting the electrodes and passing through the contact with the skin of each user; and a control means (120) configured to transmit a medium-delivery command according to the value detected.

Abstract: A control console comprising at least one member (1) for adjusting the level of radio-electric signals capable of taking up any position between two extreme positions, elements for detecting the instantaneous position of the member and elements for memorizing at least one position of the member. This console is characterized in that each adjusting member is provided with both motor mechanism for automatically positioning the adjusting member in its memorized position corresponding to a status of adjustment selected by the user and tactile elements for signalling the deviation ratio of the adjusting member relative to its predetermined memorized position. The invention is useful for mixing or lighting consoles.

Abstract: A dynamic multiple comparison device for real time monitoring of changes in incoming digital words streams. The device includes a memory (12) having N memory cells, a comparison section (13, 11, BD1, BD3, BA1) for making a series of N comparisons, a selection section (RC) for selecting after each N comparison, a digital word, a first writing section (14, BD2, W) for writing the selected N digital words, a reading section (11, BA1, BA2, CL, R) for reading the stored digital words, and a control section (17, LC) for controlling the cyclic operation of the device. The device has applications in nuclear power plant control and monitoring.

Abstract: A system for recording and broadcast studios for time multiplexed bidirectional transmission and switching high-fidelity audio-analog and audio-digital signals and command and control signals. A first bidirectional transmission medium conveys first frames produced by multiplexing the high-fidelity signals and command and control signals between a transmitter and a master receiver. The system also includes a controller with a man-machine interface (26, 32, 33, 34) receiving the high-fidelity signals transmitted by input circuits included in the transmitter and the command and control signals for monitoring in real time the evolution of the various parameters related to the signals, and for controlling in real time the modifications and configuration adaptions in the transmitter.
