Abstract: A blanket enclosure for a metallic piece of equipment and a method of fabrication, comprising at least one blanket panel and at least one magnetic support supporting the blanket panel, the magnetic support comprising at least one magnet, the at least one magnet connecting the blanket panel to a surface of the metallic piece of equipment. The method of fabrication comprises providing at least one blanket panel, providing at least one support comprising at least one magnet, supporting the blanket panel by the support, and contacting the magnet of the support supporting the blanket panel to a surface of the metallic piece of equipment.

Abstract: A method and a system for measuring amplitude and phase difference between two sinusoidal signals, using an adaptive filter. The method generally comprises measuring a sample of an output signal of a system excited by a sample of a reference signal; using an adaptive filter and the sample of the reference signal to determine a and b coefficients that minimize a prediction error on the sample of the output signal, iteratively, and determining the amplitude and/or phase of the output of the system using the a and b coefficients.

Abstract: A control method to automatically adjust the volume of a sound transmitter based on the measurement and the computation of the acoustic statistics of the room where the sound is emitted. The system comprises at least one sensor, a calculator determining statistics of the signal collected by the at least one sensor and a controller using these statistics provided by the calculator to adjust the volume of the transmitter in the room.

Abstract: A system and method for generating a masking noise level and spectrum automatically adjusted to obtain a target masking noise spectrum in a room. The system comprises a white noise generator and a mask filter automatically determined according to a correction of an acoustical response of the room and to the target masking noise corrected by an ambient noise.
