  • Patent number: 8257301
    Abstract: This device comprises a tube (22) containing several substantially parallel channels extending along the entire length of tube of which one end, referred to as distal, is connected with a connection element to the patient, thereby forming a mixing chamber for the various liquids, and of which the other end, referred to as proximal, is connected to a housing (3) provided with connection means (9) for several containers each containing a liquid, wherein the housing has liquid delivery lines (7), wherein each delivery line (7) is intended to be connected to a container and to a channel of the tube (22) respectively. At least one delivery line (7) of the housing is provided with a check valve (12) intended to prevent the passage of liquid from the channel of the corresponding tube into the corresponding container.

  • Patent number: 7893687
    Abstract: The invention relates to position sensors of the linearly variable induction difference type. When cost constraints prevent the use of transformers with guaranteed phase-shift tolerance to achieve an accuracy objective, it is advantageous to provide an independent demodulation of the signals of the two windings. The error signal thus has a lower dependence on the phase shift and the accuracy is typically enhanced by a factor greater than an order of magnitude.

  • Patent number: 7466250
    Abstract: The invention relates to an equalised time interleaved analogue digital conversion device. The analogue digital conversion device comprises a number N of analogue digital converters distributed in N channels. Each analogue digital converter has a sampling frequency N times lower than the required sampling frequency. The digital signal is built up from samples output from each channel. The device comprises a reference channel comprising an analogue digital converter generating samples of the analogue signal. Each filter comprises an equaliser filter. The filter received a digital signal output by the analogue digital converter of the channel on which it is placed. The filter also receives an error signal and outputs a filtered digital signal s(n) corrected for errors deduced from the error signal.
