20120022864 | METHOD AND DEVICE FOR CLASSIFYING BACKGROUND NOISE CONTAINED IN AN AUDIO SIGNAL - Embodiments of methods and devices for classifying background noise contained in an audio signal are disclosed. In one embodiment, the device includes a module for extracting from the audio signal a background noise signal, termed the noise signal. Also included is a second that calculates a first parameter, termed the temporal indicator. The temporal indicator relates to the temporal evolution of the noise signal. The second module also calculates a second parameter, termed the frequency indicator. The frequency indicator relates to the frequency spectrum of the noise signal. Finally, the device includes a third module that classifies the background noise by selecting, as a function of the calculated values of the temporal indicator and of the frequency indicator, a class of background noise from among a predefined set of classes of background noise. | 01-26-2012 |

20120239313 | SEALED PRESSURE-MEASURING MEMBER - A pressure-measurement device includes a pressure-measurement surface, which is functionally connected to a test body, and a sealed pressure-measurement housing in which the test body is arranged. The pressure-measurement surface is carried by a deformable wall of the sealed pressure-measurement housing lying at a distance from the test body. The sealed pressure-measurement housing delimits an internal space, which is a space internal to the sealed housing. The pressure-measurement device also includes a pressure-transmission object that transmits the pressure between the pressure-measurement surface and the test body. The pressure-transmission object includes a substantially incompressible material occupying all of the internal space. The pressure-measurement device further includes an energy source and a processor for processing pressure data detected by the test body. The processor is arranged in the sealed pressure-measurement housing. | 09-20-2012 |
