A field-operable stand-alone apparatus for recovering data from corrupted flash media and regenerated damaged flash media. The apparatus enables users in the field to recover data from and/or regenerate damaged flash media without requiring the use of a computer. In one aspect, recovery comprises using a low-level access scheme that enables data to be recovered when high-level interfaces, such as file systems, are damaged. The type of flash media is determined, and a corresponding access scheme is employed. Depending on the type of damage to the media, a physical-to-logical table may be built and employed to sequentially access the flash media in search of indicia from which selectable file-types can be identified, or the media may be accessed using normal operating system commands. Once the file indicia are found, the location of corresponding file data is identified, whereupon the file data are read and stored. The apparatus may include a plurality of different connectors to interface with different media form factors, or a universal connector that employs various form-factor adaptors to interface with the different flash media configurations.

A data storage medium has a first memory area that is read-only and stores first certification data that is unique to the data storage medium, a second memory area that stores data and second certification data supplied from the outside, an identity circuit for determining whether or not the first and second certification data are identical with each other, and a switch circuit for providing the data stored in the second memory area to the outside only when the identity circuit determines that the first and second certification data are identical with each other. If data is written into the data storage medium with illegal certification data, the data storage medium disables the reading of the written data from the data storage medium, thereby preventing the illegal copying of digital data.

A system for providing insurance associated with a lost-and-found service, according to which a person and/or item (the “insured”) is covered by an insurance policy that provides compensation in the event of at least one of loss, theft, damage, and/or destruction of an item, and in association with said insurance, also receives one or more services that facilitate the return of the item if it is lost or stolen. The insurance policy pays for the facilitation of the return of an item if it is lost by the insured and subsequently found and reported to a lost-and-found service provider. The insured pays the insurance provider a deductible for the return of the previously insured and/or lost item. Also, a lost-and-found service provider is reimbursed by the insurance provider when an item is lost in exchange for providing the services of identifying the insured using unique markings contained on a lost item owned by the insured, contacting the person associated with the item, contacting the insurance service provider (which may or may not be the same as the lost-and-found service provider), and/or facilitating the return of the lost item to the owner or insurance provider. Registering for an insurance policy also facilitates registering for the services of a lost-and-found service provider.

Disclosed is a memory card which ensures high-speed data writing operations. The memory card is formed of an erasable and programmable nonvolatile memory and a control circuit. A memory array of the nonvolatile memory has an erasing table including a first flag designating whether a memory area is a vacant area or not in every erasing unit. The control circuit exercises, when the number of memory areas in which the erasable data is written becomes a constant value, pre-erasing control to previously erase the erasable data over the memory area depending on the first flag indicating a vacant area. Since the erasing process is previously executed to the vacant memory area, necessity for insertion of the erasing process just before the writing process using the vacant memory area can be reduced and thereby writing data to the memory card can be highly speeded.

In response to receiving the disaster preparation initiation from the offsite client, the storage system to executes disaster preparation of onsite data including managing a temporary storage of onsite data volumes to at least one peer site, managing a storage of onsite cached data to a first onsite removable media, and/or managing a storage of onsite management information to a second onsite removable media.

The present invention relates to a method of recovering blocks of data recorded on an optical record carrier in case of a power failure affecting a recording and reproducing device. Said device comprises means for writing a recording indication information on the optical record carrier to indicate that a recording has started, said recording indication information including a recording start address, and means for overwriting the recording indication information at a recording end. After a power failure, if a recording indication information is written on the optical record carrier, then the recording and reproducing device is able to determine that a recording has not ended properly. In these conditions, said device is able to parse the recorded data, starting from the recording start address, in order to find the end of the improperly ended recording.

Techniques for modifying data of an image that can be implemented in a digital camera, video image capturing device and other optical systems are provided to correct for non-uniform illumination and/or effects of saturation appearing in data obtained using one or more artificial illumination sources. In an implementation, correction factors are derived using data from at least two images that have been captured with different illumination levels of the object scene and close in time to the capture of the image of interest. Typically, the image of interest is of higher resolution than at least one of the at least two images.

Data is recovered in an asynchronous environment where a sampling clock is generated internally, and is not externally frequency locked, by using programmable delay modules each providing a number of delay tap outputs. To recover data, two of the delay modules are used with a first delay module designated as a monitor delay module to monitor the clock edge transitions, while a second delay module is designated as a data delay module that provides a data output. A controller provides for incrementing or decrementing the tap delay of both delay modules to assure clock data falls at the center of the monitoring window as determined using the monitor delay module. The controller further selects between the two delay modules as to which provides data and which is used as for clock edge monitoring when the clock edge transitions drifts to an edge of the monitoring window.

A method and apparatus for receiving digital audio data which does not require the recovery of a clock from the data. Instead, the digital audio data is sampled at a rate greater than a clock rate of the digital audio data. Appropriate transitions in the digital audio data are detected to allow reconstruction of digital values represented by the digital audio data.

A dual phase pulse modulation (DPPM) decoder circuit processes a DPPM signal, which is in the form of a series of high and low pulses whose pulse widths represent successive groups of M data bits, so as to recover data carried by the signal. Each of the 2^M possible data values of an M-bit group corresponds to one of 2^M distinct pulse widths. Circuit blocks determine the width of each pulse by piping the DPPM signal through a short delay chain and inputting the delayed outputs and the non-delayed signal into AND logic gates, whose outputs are used to clock flip-flop registers. The registers are reset to a known state at the start of each signal pulse and toggled to an opposite state if clocked. The registered outputs are interpreted by logic to obtain the corresponding M-bit groups.

Systems and methods provide distributed storage and sharing of data packets in hybrid networks to enable user devices (e.g., mobile terminals) to cooperate to recover lost data packets. According to embodiments, a centralized system operable to provide data transmission may optimize broadcast resources by adjusting redundancy in data packet transmission to enable a desired or a predetermined percentage of user devices to either successfully receive transmitted data packets using transmitted redundancies or to recover lost data packets relying on the distributed storage and sharing scheme.
