Abstract: A bar code for mail pieces uses bars each of which has four possible states.  Two different bars indicate the start of the code and the same two bars in the same order indicate the end of the code. A data content identifier (DCI) follows the start bars and this indicates the structure and length of the following data field (K1A0B1) so that when the code is read it will be recognized and read properly. The use of the data content identifier (DCI) allows the code to be used for different customer and Post Office applied applications in which the code structure, length and content varies. The data field may contain a postal code with or without an address locator, a machine ID, customer information and service information. The code may include a country code field for mail pieces that are being mailed to a different country. The code may also include a field indicating whether the codeword is complete or whether it has to be concatenated with a preceding or subsequent codeword. Error protection in all cases is provided by a Reed-Solomon parity field (RS parity) following the data field. For customer applied codes this parity field may be made shorter than for Post Office applied codes because the potential for error in printing the code by the customer is less in view of the fact that he has more control over the paper quality, colour, extraneous markings, etc.

Title: Demodulation using a time domain guard interval with an overlapped transform
Inventor: WILLIAMS THOMAS H
IPC: H04J11/00
Filed: 1997-10-02
Granted: 2002-06-25
Abstract: A system and method for demodulation of an RF signal on a transmission channel is provided. The RF signal is demodulated to baseband as an in-phase (I) data signal and a quadrature (Q) data signal. A first block of I data is captured and a first block of Q data is captured. A time domain guard interval is provided in the captured first blocks of I and Q data. A complex discrete Fourier transform is performed on the captured first I and Q data blocks. An inverse frequency response for the transmission channel is determined. The inverse frequency response is multiplied by the complex discrete Fourier transform of the guard-interval protected first I and Q data blocks to generate a frequency domain product signal. An inverse Fourier transform on the product of the multiplying step is performed to generate a first equalized time domain signal. In a preferred embodiment, the method also includes using an overlapped Fourier transform and discarding a first portion of each equalized time domain signal.

Abstract: In a system for file managing image data of an electronic camera, so long as the image data is recorded by the same image pickup apparatus, a peculiar file name which is not overlapped is generated and in order to prevent that a plurality of files of the same name exist, when an electronic camera is connected to a main body of a computer, a storage device in the electronic camera is examined from a host application of the computer, and when a file of a file name including numerical values exceeding a predetermined value is found, a message is displayed for the user in a manner such that after all of the files having the file names which had automatically been formed were transferred to the computer, all of the contents in the storage device are deleted or formatted.  When the detachable storage device is loaded or a power source is turned on, if the file having the unique file name which was automatically generated does not exist in the storage device, the numerical values held in the electronic camera are initialized.

Abstract: This process treats copper concentrates, either in the form of a primary sulfide, such as chalcopyrite, or a secondary sulfide, such as chalcocite and covellite, to obtain high purity copper metal having not less than 99.99% purity. In the case of a primary sulfide, the copper concentrate is subjected to leaching and is transformed into cement or a precipitated sulfide. In the case of the secondary sulfide, the copper concentrates are subjected to leaching with ferric fluoborate and fluoboric acid. Subsequent to leaching, the solution is subjected to copper electrowinning in a diaphragm cell to deposit copper on the cathode of the diaphragm cell.

Abstract: The decision unit leaves unacceptable mail in the mail server and stores the left mail number and message ID of the latest mail in the 1st RAM as left mail number K and left mail ID, respectively. In the next access, the decision unit acquires the message ID of the Kth mail stored in the mail server and compares it with the left mail ID. If both match, the "K+1"th and subsequent pieces of mail are received. Therefore, it distinguishes the left mail and new incoming mail, avoiding repeated reception of the left mail. This makes it possible to leave E-mail in the mail server using it as a secondary storage device and distinguish the left E-mail and new incoming E-mail in subsequent accesses.

Abstract: To extract a target object having a desired size from a bidimensonal image, horizontal direction filtering suppresses image components less than the desired size in the horizontal direction and thereby outputs a result of horizontal filtering. At the same time, vertical direction filtering suppresses image components less than the desired size in the vertical direction and thereby outputs a result of vertical filtering. The results of the horizontal and vertical filtering are superposed to produce a final filtered result corresponding to the target object. During the filtering, pixel data making up the bidimensonal image are sequentially connected in the vertical or horizontal direction in a preselected connecting area to produce gradation sequence of the pixels and then subjected to FFT to transform the gradation sequence into frequency domain and to thereby frequency selection to select desired harmonics components corresponding to the target object from the FFT result.
