Abstract: A barcode decoding method includes steps of (a) capturing an image of a barcode; (b) analyzing the image to recognize a data region of the barcode; (c) decoding the data region to obtain a codeword matrix, wherein the codeword matrix includes a plurality of codewords; (d) performing an error correction for the codeword matrix; (e) when the codeword matrix fails to pass the error correction, repeating steps (a) to (c), updating the codeword matrix according to a number of occurrence times of each codeword at an identical position of the codeword matrix, and repeating step (d) for the codeword matrix after updating; and (f) when the codeword matrix passes the error correction, decoding the codeword matrix.

Abstract: A calibration apparatus and method for a capacitive sensing device, in which a calibration capacitor device connects to the capacitive sensing device which is connected to an integration circuit that generates a voltage output and a latch output, a transforming circuit transforms a sensitivity calibration parameter into a pair of corresponding analog signal outputs, and an offset calibration parameter into a corresponding analog signal output, at least two first switches between the pair of corresponding analog signal outputs and a fixed potential according to system clock's levels, and at least a third switch switches between the corresponding analog signal output and another fixed potential according to the system clock's levels. The apparatus determines the switch between the pair of signal outputs according to the latch output.

Abstract: A stacked package structure utilizes flip-chip technology to stack an acoustic micro-sensor on an integrated circuit (IC) device having a recess as a back chamber and cover the acoustic micro-sensor using a glass substrate or a planar substrate with an aperture. With the use of the stacked package structure, the package volume of the acoustic micro-sensor can be reduced effectively.
