Abstract: Data is now able to be transferred back and forth between computer systems which have disparate file systems, e.g., between a computer having a hierarchical file system and a computer having a nonhierarchical file system. The differences, however, are not limited to the file storage system. Data may now be transferred across different platforms, different human and computer languages, different binary codes, etc. From one computer system the associated metadata is stored in a interpretable format on the second computer system so that when data an d its associated metadata are transferred, the second computer system can interpret the transferred data. Data transfer can be accomplished in both directions. Thus, a tool writer or a software developer using a integrated development environment; such as Eclipse, on a Linux workstatio n with its hierarchical file system may download source files and other resources from an iSeries computer server with its OS/400 nonhierarchical file system, modify the resources; and then put them back onto the iSeries machine for use on the iSeries. The metadata of the source file and other resources are stored in a .properties file which, if in XML format, supports the transfer of resources across the Internet.

Patent CA-2392910-A1 (CA)
Inventor: LOPEZ ESTELL
IPC: G01N27/90
Filed: 2002-07-10
Abstract: A digital synthesizer generates an electrical digital carrier that drives probe coil to generate an electromagnetic wave propagated into a test material proximate the probe coil. A return electromagnetic wave generated by eddy currents in the material includes signatures of material defects modulated on the return carrier electromagnetic wave. The return wave is detected by one or more probe coils, amplified, converted from an analog signal to a digital signal and then digitally mixed with digital sine and cosine functions also generated by the digital synthesizer to yield sum and difference values, mathematically expressing various eddy current signals received by the probe in a complete set of orthogonal functions. A low pass filter then removes all but the difference values. A direct current reference component is subtracted from the mixed digital signal, which translates the signal to center about a zero axis for ease of display and analysis.

Title: Method and system for transmission of decrypting information
Inventor: SASSELLI MARCO
IPC: H04N21/4623
Filed: 2001-01-24
Abstract: At the moment of the diffusion of Pay-TV with multi-channel signals, each channel is associated to authorization messages (ECM) which allow to decrypt this channel according to the rights of the subscriber. When changing channel, a very short time is accepted before one has determined these new rights in relation with the new channel. The heavy encrypting algorithms are thus excluded. To avoid this drawback, to decrypt a channel, a system is proposed using the combination of the authorization information for a channel (ECM), and thus encrypted by a fast algorithm, with authorization information (MECM) for a group of channels. These latter are encrypted by a high security algorithm and are thus slower to decrypt.

Abstract: An FPGA architecture and method enables partial reconfiguration of selected configurable logic blocks (CLBs) connected to an address line without affecting other CLBs connected to the same addressl line. Partial reconfigutration at a memory cell resolution is achieved by manipulating the input voltages applied to the address and data lines of the FPGA so that certain memory cells are programmed while other memory cells are not programmed. In addition, partial reconfiguration at at CLB resolution can be achieved by hardwiring the FPGA to enable selection of individual CLBs for reconfiguration.
