  • Publication number: 20240353441
    Abstract: An ocean current detection device and method based on double-helix and double-core vibration fiber-optic cable, comprises a double-core fiber-optic cable and a ?-OTDR system; the double-core fiber-optic cable comprises a first and a second optical fiber core, provided symmetrically in the double helix structure. The terminate ends of the first and the second optical fiber core are connected, and the start end of the first or the second optical fiber core is connected with the ?-OTDR system. When measuring the ocean current characteristics in the target sea area, the double-core fiber-optic cable is provided underwater to generate vortex-induced vibration. The ?-OTDR system is provided for emitting laser towards the cable, receiving returned double-core vibration signals, extracting vibration characteristics from the double-core vibration signals to determine ocean current characteristics, including ocean current flow velocity and direction, to improve the detection accuracy.

  • Patent number: 8031882
    Abstract: A speaker feedback system has a linear current feedback derived from a current sensing resistor. A linear motional feedback from the active speaker driver is derived from a sensing coil mechanically coupled with the driver coil of the speaker, the driver coil receiving electrical energy from the power amplifier. A motional signal correction circuit extracts the motional signal from the sensing coil and feeds to input B of the multiplier. A current filter circuit filters out higher-frequency signals from the current feedback signal and then feeds to input A of the multiplier. A multiplier performs the multiplication function of its two inputs and produces an output. Post-multiplier equalization circuitry that control the feedback gain of the nonlinear feedback system such that it can effectively compensate for the effect of flux modulation over the targeted frequency range. A feedback network feeds the output from post multiplier equalization to the power amplifier.

  • Patent number: 6104817
    Abstract: A sound reproduction system employs at least one amplifier system and at least one speaker. The speaker provides two negative feedback signals: one indicative of the current through the speaker voice coil and a second indicative of the velocity of the speaker diaphragm. The current signal is provided via a first feedback path to an input of the amplifier in the amplifier system. The velocity signal is provided via a second feedback path to an input of the amplifier. The current signal may be derived from the voltage drop across a resistor placed in series with the speaker voice coil. The velocity signal may be derived from a second voice coil coupled to the diaphragm, or may be derived from a piezoelectric sensor coupled thereto.

  • Patent number: 5764781
    Abstract: An improved sound reproduction system employs an amplifier system and a speaker. The system offers greatly improved bass response. The speaker provides two negative feedback signals, one indicative of the current through the speaker voice coil and a second indicative of the velocity of the speaker diaphragm. The velocity signal is provided via the first feedback path to an input of the amplifier of the amplifier system. The current signal is provided by the second feedback path through a bandpass filter to the amplifier input. The velocity measurement may be derived from a second voice coil coupled to the diaphragm, or may be derived from a piezoelectric sensor coupled thereto. The current signal may be derived from the voltage drop across a resistor placed in series with the speaker voice coil.
