A position-encoding device includes a sensing device, a filtering device, a calibrating device and a compensating device. The sensing device senses the motion of a moving device to generate first and second signals. The filtering device filters the first and second signals to generate first and second filtering signal. The calibrating device captures the first and second filtering signals to obtain time and phase information of the first and second filtering signals, performs gain and offset calibration on the first and second filtering signals, and performs a phase calibration on the first and second filtering signals through first, second feedback signals and the time and phase information of the first and second filtering signals to generate first and second calibrating signals. The compensating device compensates for the first and second calibrating signals according to a lookup table, so as to generate first and second position encoding signals.

Position-encoding device and method

An automatic identification system for a car-plate which comprises a photographing apparatus and an image-processing CPU. The system disclosed in the present invention can be mounted in a car for automatically identifying a car-plate that is under a still or moving condition. The photographing apparatus is used for taking the image of a car-plate, and the image is then transmitted into the image-processing CPU, which accurately extracts the characters of a car-plate using a 'Fuzzy inference' technique, and identifies the characters through a character structure analysis neural network. With the automatic identification system of the present invention, an incorrect identification can be avoided in the event the image of a car-plate is blurred, and the characters is deformed or smeared.
