Error checking and correction techniques for web based applications use an error checking routine on a server or a client station to find errors in electronic text of an E-mail message. The disclosed error checking routine detects errors such as spelling errors in the electronic text and creates a correction file of the electronic text containing tags, markers and other information allowing errors to be displayed and corrected using the user's graphical interface. The graphical interface allows the user to review all the errors concurrently in the correction file and to correct the errors in any order. In a preferred embodiment, correction is facilitated in response to the user moving a mouse pointer over an error of interest, which provides correction options to be displayed in-line with the original text. The user can then select a suitable correction to correct the error.

A multidrop network of multichannel, addressable sensing modules (ASM's), to be embedded within a composite structure, remotely powered, and interrogated by a personal computer through a non-contacting inductive link. Each ASM contains a microprocessor with non-volatile memory, multiplexer, programmable gain and filter instrumentation amplifier, and sigma delta analog to digital converter (all housed in two thin surface mount packages). An embedded mothernode includes circuitry for power and data reception (into the structure), and data transmission (back out of the structure). The external interrogation system communicates into the network of ASM's by modulating the AC waveform that delivers power to the embedded electronics. Once addressed, each ASM powers up its programmable (gain & filter) sensing channels (3 full differential or 5 pseudo differential) and data conversion elements. Sensed data are pulse code modulated, including error checking, which serially modulate an RF carrier for wireless transmission out of the composite to the interrogating computer. These advanced, micro-miniature sensing networks may be applied to a wide variety of military, medical, & civil structures.

A computer system includes a processor coupled to a DRAM through a memory controller. The processor switches the DRAM to a low power refresh mode in which DRAM cells are refreshed at a sufficiently low rate that data retention errors may occur. Prior to switching the DRAM to the low power refresh mode, the processor identifies a region of an array of DRAM cells that contains essential data that needs to be protected from such data retention errors. The processor then reads data from the identified region, and either the DRAM or the memory controller generates error checking and correcting syndromes from the read data. The syndromes are stored in the DRAM, and the low power refresh mode is then entered. Upon exiting the low power refresh mode, the processor again reads the data from the identified region, and the read data is checked and corrected using the syndromes.

A downlink telemetry system providing improved apparatus and methods for communicating instructions via pressure pulses from surface equipment to a downhole assembly. The apparatus comprises a surface transmitter for generating pressure pulses, a control system, and a downhole receiver for receiving and decoding pulses.In operation, a bypass valve is opened and closed to create a series of pressure pulses received and decoded by a downhole receiver. The method significantly reduces the time required for downlink communication without interrupting drilling and without interrupting uplink communications such that simultaneous, bi-directional communication is achievable if the uplink and downlink signals are sent at different frequencies.The telemetry scheme and algorithm provide an inventive method for filtering and decoding the downlink signals. The algorithm determines the time intervals between pulse peaks and decodes the intervals into an instruction. The algorithm also includes error checking for verifying that the instruction was properly received downhole.

Disclosed is a method, system, and data structures for updating data in a storage device. An update to one or more blocks of customer data at addresses in the storage device is received. For each block of data to update, metadata is generated indicating the address of the block in the storage device and an error checking code that is capable of being used to determine whether the customer data in the block has changed. For each block of data to update, the block of data to update and the metadata for the block are written to cache. Further, for each block of data to update, the block of data and the metadata are transferred for the block from the cache to the storage device. The metadata may be used during power loss and recovery.

The disclosure is a NAND flash memory with the function of error checking and correction during a page copy operation. The NAND flash memory is able to prohibit transcription of erroneous bits to a duplicate page from a source page. Embodiments of the inventive flash memory include a correction circuit for correcting bit errors of source data stored in a page buffer, a circuit configured to provide the source data to the correction circuit and to provide correction data to the page buffer, and a copy circuit configured to copy the source data to the page buffer, and to store the correction data in the other page from the page buffer.

A bi-directional reflective memory channel between a pair of storage controllers is used to maintain a mirrored copy of each storage controller's native buffer contents within the buffer of the other storage controller. To maintain such mirrored copies, buffer write operations that fall within a reflective memory segment of one storage controller are automatically reflected across this channel to the other storage controller for execution, and vice versa. The write operations are preferably transmitted across the reflective memory channel using a protocol that provides for error checking, acknowledgements, and retransmissions. This protocol is preferably implemented entirely in automated circuitry, so that the mirrored copies are maintained without any CPU intervention during error-free operation. When a failover occurs, the surviving storage controller uses the mirrored copy of the failed storage controller's native buffer contents to assume control over the failed storage controller's disk drives.

A group of headless computer entities is formed via a local area network connection by means of an aggregation service application, operated on a headless computer entity selected as a master entity, which propagates configuration settings for time zone, application settings, security settings and the like across individual slave computer entities within the group.

Addition and subtraction of computer entities from a group are handled by an aggregation service application, and interlocks and error checking is applied throughout the group to ensure that no changes to a slave computer entity are made, unless those changes conform to global configuration settings enforced by the master headless computer entity.

The system may use more than one human agent, or both human agents and speech recognition software, to interpret simultaneously the same component for error-checking and interpretation accuracy.

A non-volatile memory chip having SLC blocks acting as a write cache for MLC blocks for high density storage requires constant copying or folding of SLC blocks into MLC blocks. To avoid the time-consuming toggling out and in of the pages of the entire SLC block for ECC checking by a controller chip, only a small sample is checked. An optimal read point for reading the memory cells in the sample of the SLC block is dynamically determined by trying different read points so that the data is read within an error budget. Once the optimal read point is determined, it is used to read the entire SLC block without further error checking. Then the SLC block can be copied (blind folded) to the MLC block with the confidence of being within the error budget.

A scheduled data communication system of an access node and terminal supports recurring communications of small data amounts such as Voice over IP (VoIP). In order to make error checking more robust in a random access response (RAR), such as for semi-persistent scheduling (SPS) for VoIP, a portion of a grant or assignment payload has a constraint imposed that can be verified as a condition precedent to determining a valid grant or assignment rather than only relying upon a validity check field, such as a cyclic redundancy check (CRC). Thereby, incorrect validation of a grant or assignment is avoided for dynamic scheduling or for semi-persistent scheduling, the latter causing a persistent error.
