The paper presents things regarding motion circuit, methods, algorithms, voltage, response, sampling pulse, ﬂicker noise, digital signal processing, the temporal edge, voltage pulses, pulses, and nonlinear ﬁlter. There are lots of information related to edge detectors, sensitivity, pulse shaping circuit, motion sensors, shaping circuit, circuits, the sampling pulse, motion circuits, output, edge detector, velocity, and the motion circuits are explained inside the paper.
Inside the paper the reader can learn description such as sensing elements, signals, output pulse, vlsi velocity sensors, range, output voltage, signal processing, signal, current pulses, pulse, sensors, and temporal edge detector. Here are chosen from this paper:
The width of the output pulse of the motion circuit (M) equals the overlap time of the facilitation pulse (P1 ) and the trigger pulse (P2 ), if the facilitation pulse precedes the trigger pulse. Note that a single motion sensing element in a 1-D array contains a pair of motion circuits, but only one edge detector and one pulse-shaping circuit, because the pulses are shared among neighboring motion circuits. The FT motion sensor uses a nonlinear ﬁltering circuit to convert the current pulse from the edge detector into a thin voltage spike that is translated into a voltage pulse of ﬁxed amplitude and width by a refractory neuron circuit.
Furthermore, this paper presents info things like sensor, motion sensor, velocity sensors, the nonlinear ﬁlter, optical, illumination, photoreceptor, image velocity, the edge detector, system, and circuit.
