A detachable insulation wire-pressing element of a stapling device is disclosed. The program is constructed by a remote knowledge based analysis tool, accessible by the medical device over a network such as the Internet. A reader or a scanner within the system receives a signal from the product identification element containing product identity information about the product. The expandable anchor of the tubular body has an annular ring concentric with a longitudinal axis defined by the tubular body. The method comprises the steps of: outputting data for an image of an object; downsampling the outputted data; transforming the downsampled data into low-resolution image frequency data; and reconstructing a high-resolution image from the transformed low-resolution image frequency data by applying focal underdetermined system solver algorithm. According to one embodiment, for each data range of parameters to be encoded, a number of bits required to represent a maximum parameter among the parameters in each data range is determined, including a first number of bits and a second number of bits corresponding to the first and second data ranges.
