  • Publication number: 20250189565
    Abstract: A power detector may include a transformer, first and second multipliers, a peak voltage detector, and a biasing circuit. The transformer may be configured to sense an electrical current of a load and to provide an image current of said electric current. The first multiplier may be configured to perform a multiplication of the image current with a sign of a voltage of the load and to feed a result of said multiplication to a filter to provide a DC signal. The peak voltage detector may be configured to determine a peak value of the voltage. The second multiplier may be configured to perform a linear multiplication of the output of the filter with the peak value. The biasing circuit may be configured to provide a biasing signal for the first multiplier that is independent of one or more of temperature or process of the first multiplier.

  • Patent number: 11698128
    Abstract: A lubricating liquid manifold for a crankpin of an epicyclic gear train. The epicyclic gear train is lubricated by a lubrication system conveying a first flow of a lubricating liquid towards the manifold and a second flow of the lubricating liquid towards a member to be lubricated. The manifold comprises a hollow body provided with an inlet port intended to receive the first flow and an outlet port designed such that the first flow is conveyed towards a guide device connected to the crankpin. The manifold comprises a barrier comprising a shoulder connected to the body and a deflector protruding radially outwards from the body so as to form, with the shoulder, a diversion space for diverting the second flow and preventing it from penetrating into the manifold.

  • Patent number: 11054401
    Abstract: A method for processing ultrasound signals including controlling emission transducers for M successive emissions of plane ultrasound waves having M different angles of emission, controlling N reception transducers in order to simultaneously receive N measurement time signals per emission, and obtaining a matrix [MR(t)] of ultrasound time signals, each coefficient MRi,j(t) of this matrix representing the measurement signal received by the i-th reception transducer caused by the j-th emission.

  • Patent number: 10581474
    Abstract: Wireless receivers and related methods with interferer immunity are disclosed. The receiver includes a receive (RX) front-end, a power level detector, and an automatic gain controller (AGC). The RX front-end includes circuit(s) having variable gains, and the power level detector outputs a power level indicator. The AGC receives the power level indicator and outputs the gain settings to the variable-gain circuits within the RX front-end. Further, the AGC is configured to adjust the gain settings within a first gain range when not receiving data frames and to adjust them within a second gain range when receiving data frames. The second gain range is a restricted version of the first gain range. Further, the AGC can be configured to detect and store gain settings within a sliding time window when data frames are not being received and to use these stored gain settings to determine the second gain range.
