Abstract: An optical inspection system includes at least one lighting module, a plurality of image-sensing units, and an editing and computing unit. Each lighting module is configured to generate a light beam for illuminating an object; each image-sensing unit is configured to capture an inspecting image of the object, wherein two adjacent inspecting images of the object has a repeated image; the editing and computing unit receiving the inspecting images captured by the image-sensing unit is configured to position the inspecting images in accordance with the repeated images and then recombinant the inspecting images for creating a full inspecting image.

Abstract: A bicycle carrier includes a main body, at least one supporting frame, at least one side frame and at least one restrainer. The main body includes a supporting plane and a plurality of slide bases. The slide bases are located on at least one side of the main body. The supporting frame connects the main body and the bicycle. The side frame includes at least one slide rod that slides and couples to the slide bases and at least one fence connected to the slide rod to define a container space. The restrainer restrains the side frame from moving relative to the main body.

Abstract: There is provided a signal demodulating method of a two-phase frequency shift keying (FSK) digital demodulator. The method utilizes at least a detect circuit respectively detecting and collecting a positive edge signal and a negative edge signal of an intermediate frequency signal. Then, two n-bit ripple counters are utilized to refer to a threshold value and then receiving the positive and negative edge signal as a switch signal to reset the threshold value as an initial value of counters so as to start to count and compare to output a positive edge data bit and a negative edge data bit. Last, a hard decision logic circuit is used to perform a frequency-descending decision in accordance with the positive and negative edge data bit so as to send a base frequency signal. The method can decrease the logic gate counts, shorten the signal delay time, and increase the resolution of the demodulation.
