Abstract: An electrode comprises a porous three-dimensional conductive support and at least one reinforcing metal band fixed along a longitudinal edge portion of the support and having a coefficient of elongation to rupture equal to at least 20% in a direction parallel to the edge portion of the support. Two longitudinal edge portions of the band are bent against the same face of the band, at least part of whose surface is pressed against the support.

Abstract: An integrated, multi-input audio mixer receiving a plurality of analog input signals, internally digitizing the analog input signals, digitally processing and mixing the digitized input signals and producing both digital and analog representations of the mixed inputs. All analog inputs are applied to half of a full delta-sigma analog-to-digital converter. That is, each input is applied to a respective delta-sigma modulator, but all the delta-sigma modulators share a single sigma-decimation filter. The output of each delta/sigma modulator controls a respective multiplexer having a separate input channel for each quantization level of its respective delta/sigma modulator. The output of the multiplexers is selectively applied to a summing circuit. The output from the summing circuit is applied to a D/A converter to provide an analog output, and is also applied to the single sigma-decimation filter, which recovers the mixed data from the delta/sigma modulators.

Abstract: The present invention relates to a temperature measuring device including an alarm contact, in particular for motor vehicles, the device comprising a housing (10) which receives a bimetallic strip (20) and a thermoresistive element (150). According to the invention, a support (100) of electrically insulating material is provided to carry a contact stud (160), a contact blade (170), the thermoresistive element (150) interposed between the contact stud (160) and the contact blade (170), and a spring element (180), all in the form of a unitary module.
