  • Publication number: 20150100263
    Abstract: A method for measuring a magnetic field via a Hall cross (12) including two orthogonal branches (120, 122), in which, for a given state of the Hall cross, a polarization current is made to flow in one of the branches of the Hall cross, referred to as the “polarization branch”, and a voltage is measured in the other branch, referred to as the “measurement branch”, the measured voltage including a useful signal representing the magnetic field, the method including the modulation of the useful signal via a switching sequence consisting in placing the Hall cross in Nb successive states, and the demodulation of the useful signal. The switching sequence is furthermore chosen in such a way that a measurement bias and interference pulses are zero-mean after demodulation. A switching Hall-effect sensor (10) is also described.

  • Patent number: 8297114
    Abstract: Device for measuring cylinder pressure of an internal combustion engine includes a pressure sensor that includes a piezoelectric element associated with a capacitive element, and an output generating a first voltage representative of the cylinder pressure. A filtering module of the device filters parasitic low-frequency voltages and generates a second voltage free of these parasitic voltages. A control module delivers a control signal that is dependent on a switching parameter correlated with a stroke. A switching module, in response to the control signal, disconnects the input of the filtering module from the output of the pressure sensor during the first stroke and connects the input of the filtering module to the output of the pressure sensor during the second stroke. The first stroke corresponds to a compression stroke or to a combustion-expansion stroke, and the second stroke corresponds to an intake stroke or to an exhaust stroke.
