Abstract: A neuron network signal detection device is disclosed herein, comprising at least two coupled neurons, each neuron is connected to a sensor that transmits DC signal and the output terminal of coupled neuron is connected to a synchronization judgment unit. When adopting the above scheme, the physical or biological signals are converted to DC signals, which act on the mutually coupled neuron or neuron-like circuit. When the coupling strength reaches a certain value, the discharge behaviors of neuron or neuron-like circuit network will also achieve synchronization, and the synchronization judgment unit can detect the output voltage or current response of this kind of circuit.

Abstract: Disclosed are mechanisms for an impeller (10, 20, 40) and method of reducing noise levels while driving fluids with impellers. Exemplary implementations include a hub (21, 41) and multiple blades (22) separably attached to or inseparably formed on the hub. The hub may be used to effectively reduce noise levels during operations of the impeller by having a first cylindrical feature (261), a first number of first ribs (27, 47, 706), and a second number of second ribs (281, 48, 708), while maintaining substantially similar mechanical properties or operational characteristics. The hub may further optionally include a second substantially cylindrical feature (704) that is separably attached to or is inseparably formed on the hub to further enhance one or more properties or characteristics of the hub while serving to reduce the noise level of the impeller.
