The present invention relates to an architecture for stack robust fine granularity scalability (SRFGS), more particularly, SRFGS providing simultaneously temporal scalability and SNR scalability. SRFGS first simplifies the RFGS temporal prediction architecture and then generalizes the prediction concept as the following: the quantization error of the previous layer can be inter-predicted by the reconstructed image in the previous time instance of the same layer. With this concept, the RFGS architecture can be extended to multiple layers that forming a stack to improve the temporal prediction efficiency. SRFGS can be optimized at several operating points to fit the requirements of various applications while the fine granularity and error robustness of RFGS are still remained. The experiment results show that SRFGS can improve the performance of RFGS by 0.4 to 3.0 dB in PSNR.

The SSD performs to encode input data from the host device into BCH code having data length Sdr and code length Scr sequentially (step S100 and step S110) and controls RRAM to stores the encoded data (step S120) when the write requesting signal is input from the host device. When the number of BCH code that becomes data of one page of the flash memory after being decoded is stored to RRAM (step S130), the SSD controls RRAM to read out data stored in RRAM (step S140), performs error correction and decoding to the read data as BCH code having the data length Sdr and the code length Scr, and controls the flash memory to store the encoded data.

When image data is converted into an expression format based on the dot on-off state, such conversion is performed in a unit of a raster group comprising a predetermined number of adjacent rasters. When this is done, the binarization errors occurring in each pixel of the last raster located in the last position of such raster group are diffused into surrounding pixels and stored in a first storage unit. The errors are read out from the first storage unit for dot on-off state determination regarding the first raster of the raster group adjacent to the above-mentioned last raster, and binarization errors occurring in connection with this determination are stored in a second storage unit that permits faster reading and writing of data than the first storage unit. The remaining rasters following the first raster are converted into dot rows by conducting dot on-off state determination for each pixel therein in parallel with the process to convert the first raster into a dot row while taking into account the binarization errors that occurred in the first raster. Consequently, the errors that are taken into account by the pixels of the same raster are stored in the second storage unit that permits faster high-speed reading and writing of data, and the image data for the raster group can be converted at a high speed.

A scanner instrument used for scanning tubing that is being placed into an oil well or being removed from the oil well can be calibrated during retrieval of tubing from the well. Calibrating the tube scanner includes scanning a tubing standard and comparing the data from the standard scan to the known characteristics of the standard. The relationship between the scanned data and the known characteristics can be computed. The relationship between the scanned data and the known characteristics can be used as the calibration function for the scanner. Calibrating the tube scanner can also include scanning a string of tubing segments and then adjusting the data collected. The adjustment is based upon equalizing the data peaks that occur in the scan data at the coupling joints between tube segments.

Prior to updating of an information processing program that stores a program update module for updating a wireless interface driver or the information processing program used for communications with a router, a printer stores the minimal information necessary for communications such as the wireless interface driver or setting information (SSID, Wep key, etc.) necessary for using the wireless interface driver in basic update user information stored in an area different from an area for the information processing program. If updating of the information processing program is suspended and an error occurs in the information processing program, a basic update module protected from overwriting utilizes the basic update user information to restart communications with the router.

A controller includes a rotating direction detecting unit 34 to detect the rotating direction of a servo motor 6, a reversing distance computing unit 31 to compute a rotating angle of the servo motor 6, a rotation resistance computing unit 35 to compute rotation resistance on the servo motor side 6, and an elastic deformation error amount computing unit 21 to compute a deformation error amount of a ball screw 3. In the controller, when the rotating direction detecting unit 34 detects reverse of the servo motor 6, the rotation resistance computing unit 35 computes rotation resistance based on a rotating angle δθ of the servo motor 6 after the servo motor is reversed. The elastic deformation error amount computing unit 21 computes the elastic deformation error amount δ based on the computed rotation resistance. Thereby, a position command value inputted into the position control unit 14 can be corrected.

Error correction and error detection related to DRAM chip failures, particularly adapted server memory subsystems. It uses ×4 bit DRAM devices organized in a code word of 128 data bit words and 16 check bits. These 16 check bits are generated in such a way as to provide a code capable of 4 bit adjacent error correction within a family (i.e., in a ×4 DRAM) and double bit non-adjacent error detection across the entire 128 bit word, with single bit correction across the word as well. Each device can be thought of as a separate family of bits, errors occurring in more than one family are not correctable, but may be detected if only one bit in each of two families is in error. Syndrome generation and regeneration are used together with a specific large code word. Decoding the syndrome and checking it against the regenerated syndrome yield data sufficient for providing the features described.
