Abstract: A feed detecting system includes a sending element, a receiving element, a filtering-amplifying circuit, a peak-holding circuit, an A/D converter and a processing unit. The receiving element receives an ultrasonic signal sent by the sending element, and then outputs an electric signal, the filtering-amplifying circuit receives, filters and amplifies the electric signal, the A/D converter converts the electric signal to a digital signal, the processing unit reads the digital signal and compares the digital signal with a standard value stored in the processing unit. In this present invention, the A/D converter can be a low frequency A/D converter, so the cost of the feed detecting system is reduced.

Abstract: A method for compressing image data is used to process image data. The method includes the following steps as sampling pixels expressing an image, transforming the sampling data into transformed data by forward discrete cosine transformation, quantifying the transformed data according to a quantification table into quantified data, encoding the quantified data according to Huffman table, and generating a frame data. When the frame data is processed along the reverse pipeline, the frame data is decompressed to the image data.

Abstract: The present invention discloses a method by utilizing chemical reaction or specific attractive forces (complexation or hydrogen bonding) for forming self-synthesizing conductive or conjugated polymer film and its application. First of all, at least one photoresist layer with a first functional group and a specific pattern is formed, so that the first functional group can bond a second functional group of a conductive or conjugated polymer unit, whereby a conductive or conjugated polymer film with specific pattern is formed. Furthermore, this invention can be applied for forming emitting films, especially for forming emitting layers of OLED/PLED elements.
