An accelerometer uses variations in capacitance to detect and measure the movement of a moving mass in relation to a fixed part. The accelerometer comprises a first series of electrodes, which are solidly connected to the mass and which are interdigitated with a second series of electrod
The invention relates to an apparatus and a method for data acquisition, the apparatus being characterized in that it comprises an analog/digital converter (510) sampling at an imperfect frequency F.sub.E provided by a local clock (100) data acquired by a sensor (500) thus providing a se
A seismic data acquisition system includes a plurality of sensors which are arranged so they can be used to measure translation movements of a medium with three independent spatial components and of the rotation movements around each of the three independent spatial components, thus
