A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to raw data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On retrieval, the calculation is repeated and, in the event the check values do not match, corrective action can be taken against data corruption. CRCs can be used for error correction (see bitfilters).
Interference protection
InactiveUS7239657B1Memory record carrier reading problemsTransmissionInterference resistanceChecksum
Apparatus and a method for enhancing the interference resistance of so-called RFID systems, wherein identification messages delivered from an identification device are longer than the time for which an anticipated interference or disturbance is calculated to continue, and wherein the messages contain redundancy, such as a checksum. The messages are delivered from the identification device repetitively, and are redundancy checked. In the event of any discrepancy in the redundancy check, such as when the checksum is checked against the data content of the message and is found in disagreement, successive messages are checked bit for bit against each other. Any deviations between otherwise previously rejected messages are assumed to be due to external interference and are thus successively substituted until the redundancy check gives an accepted result, such as through the medium of a checksum check according to the so-called CRC method.

A wireless communications adapts its mode of operation between spatial multiplexing and non-spatial multiplexing in response to transmission-specific variables. An embodiment of a wireless communications system for transmitting information between a base transceiver station and a subscriber unit includes mode determination logic. The mode determination logic is in communication with the base transceiver station and the subscriber unit. The mode determination logic determines, in response to a received signal, if a subscriber datastream should be transmitted between the base transceiver station and the subscriber unit utilizing spatial multiplexing or non-spatial multiplexing. In an embodiment, the mode determination logic has an input for receiving a measure of a transmission characteristic related to the received signal. In an embodiment, the mode determination logic includes logic for comparing the measured transmission characteristic to a transmission characteristic threshold and for selecting one of spatial multiplexing and non-spatial multiplexing in response to the comparison of the measured transmission characteristic to the transmission characteristic threshold. In an embodiment, the transmission characteristic includes at least one of delay spread, post-processing signal-to-noise ratio, cyclical redundancy check (CRC) failure, residual inter-symbol interference, mean square error, coherence time, and path loss. By adapting the mode of operation in response to transmission-specific variables, the use of spatial multiplexing can be discontinued in unfavorable conditions. Additionally, because the wireless communications system can adapt its mode of operation between spatial multiplexing and non-spatial multiplexing, the communications system is compatible with both subscriber units that support spatial multiplexing and subscriber units that do not support spatial multiplexing.

A computer random access memory is divided into first and second partitions. Each partition has its own operating system (OS). The first partition has a conventional OS and is designated for non-Internet use. The second partition is designated for secure Internet access, and has an OS specific for Internet usage. Software in the second partition cannot write or copy files in the second partition. The size of the second partition is fixed and unchangeable while said second partition is open. Each software application in the second partition is allocated a memory region that cannot be changed, thereby preventing memory overflow attacks. A secure memory is designated for temporary storage of software used in the second partition. Cyclic redundancy check (CRC) values are calculated for all files in the secure memory. To detect unauthorized file changes, CRC values are calculated for all files used in the second partition, and checked against values stored in the secure memory. The second partition can write only to a secure memory using a security arrangement such as password protection or a download memory separate from the first partition to allow files stored in the download memory to be examined by scanning and testing from the first partition prior to being stored elsewhere in the computer.

A dynamic-content web crawler is disclosed. These New Crawlers (NCs) are located at points between the server and user, and monitor content from said points, for example by proxying the web traffic or sniffing the traffic as it goes by. Web page content is recursively parsed into subcomponents. Sub-components are fingerpinted with a cyclic redundancy check code or other loss-full compression in order to be able to detect recurrence of the sub-component in subsequent pages. Those sub-components which persist in the web traffic, as measured by the frequency NCs (6) are defined as having substantive content of interest to data-mining applications. Where a substantive content sub-component is added to or removed from a web page, then this change is significant and is sent to a duplication filter (11) so that if multiple NCs (6) detect a change in a web page only one announcement of the changed URL will be broadcast to data-mining applications (8). The NC (6) identifies substantive content sub-components which repeatably are part of a page pointed to by a URL. Provision is also made for limiting monitoring to pages having a flag authorizing discovery of the page by a monitor.

Address error detection by merging a polynomial-based CRC code of address bits with two nibbles of data or data ECC bits
A memory system provides data error detection and correction and address error detection. A Single-byte Error-Correcting / Double-byte Error-Detecting (SbEC / DbED) code with the byte being a 4-bit nibble is used to detect up to 8-bit errors and correct data errors of 4 bits or less. Rather than generating address parity, which is poor at detecting even numbers of errors, a cyclical-redundancy-check (CRC) code generates address check bits. A 32-bit address is compressed to just 4 address check bits using the CRC code. The 4 address check bits are merged (XOR'ed) with two 4-bit nibbles of the data SbEC / DbED code to generate a merged ECC codeword that is stored in memory. An address error causes a 2-nibble mis-match due to the redundant merging of the 4 address check bits with 2 nibbles of data correction code. The CRC code is ideal for detecting even numbers of errors common with multiplexed-address DRAMs.

Data transmission using arithmetic coding based continuous error detection
InactiveUS6418549B1Error prevention/detection by using return channelTransmission systemsAutomatic repeat requestTrade offs
Method and apparatus for image transmission using arithmetic coding, based on continuous error detection uses a controlled amount of added redundancy. A continuous error detection scheme is provided, wherein there is a trade-off between the amount of added redundancy and the time needed to detect an error once it occurs. Herein, there is no need for the cyclic redundancy check (CRC) to wait until an entire block of data has been received and processed before an error can be detected. The invention can be used to great advantage both in the automatic repeat request (ARQ) and other concatenated coding schemes. Errors in the received bit stream are detected by introducing added redundancy, e.g., a forbidden symbol, in the arithmetic coding operation. The forbidden symbol is never intended to be encoded. The redundancy error causes loss of synchronization, which is used to detect errors. If a forbidden symbol gets decoded, it means that an error has occurred. In this invention, there is direct control over the amount of redundancy added vs. the amount of time it takes to detect an error. For image compression systems, by using the invention and ARQ, only one device would suffice both for source compression and channel coding.
