System and method for retrieving and using block fingerprints for data deduplication
ActiveUS20080005141A1Efficient identificationImprove performanceDigital data information retrievalDigital data processing detailsData deduplicationFingerprint database
A system and method for calculating and storing block fingerprints for data deduplication. A fingerprint extraction layer generates a fingerprint of a predefined size, e.g., 64 bits, for each data block stored by a storage system. Each fingerprint is stored in a fingerprint record, and the fingerprint records are, in turn, stored in a fingerprint database for access by the data deduplication module. The data deduplication module may periodically compare the fingerprints to identify duplicate fingerprints, which, in turn, indicate duplicate data blocks.

Apparatus for and method of coordinating transmission and reception opportunities in a communications device incorporating multiple radios
InactiveUS20090180451A1Avoid interferenceDelay transitionNetwork topologiesSubstation equipmentOperation modeMobile station
A novel and useful apparatus for and method of coordinating the allocation of transmission and reception availability and / or unavailability periods for use in a communications device incorporating collocated multiple radios. The mechanism provide both centralized and distributed coordination to enable the coordination (e.g., to achieve coexistence) of multiple radio access communication devices (RACDs) collocated in a single device such as a mobile station. A distributed activity coordinator modifies the activity pattern of multiple RACDs. The activity pattern comprises a set of radio access specific modes of operation, (e.g., IEEE 802.16 Normal, Sleep, Scan or Idle modes, 3GPP GSM / EDGE operation mode (PTM, IDLE, Connected, DTM modes), etc.) and a compatible set of wake-up events, such as reception and transmission availability periods. To prevent interference and possible loss of data, a radio access is prevented from transmitting or receiving data packets while another radio access is transmitting or receiving. In the event two or more RATs desire to be active at the same time, the mechanism negotiates an availability pattern between the MS and a corresponding BS to achieve coordination between the RATs.

InactiveUS20050113070A1Shorten the timePreventing fraudulent data transmission/receptionUnauthorised/fraudulent call preventionEavesdropping prevention circuitsReceiptRadio access point
A mobile terminal transmits an N-th authentication key to an authentication server when the mobile terminal has moved from a coverage area under a certain radio access point to a coverage area under another radio access point. The N-th authentication key is generated by applying a hash function to a random number a number of times one smaller than an (N−1)th authentication key which was transmitted when the mobile terminal moved to the coverage area under the certain radio access point. Upon receipt of the N-th authentication key from the mobile terminal, the authentication server applies the hash function once to the N-th authentication key, and compares the result with the (N−1)th authentication key. Then, the authentication server determines that the authentication is successful when there is a match between both keys.

A Virtual Storage Server is provided for transferring data between a source storage device and one or more destination storage devices. A write command is issued to the one or more destinations for an amount of data. In response, one or more Transfer Ready Responses are returned indicating the amount of data the destinations are prepared to receive. The Virtual Storage Server then sends a read command to the source for an amount of data based on the amounts of data in the Transfer Ready Responses. The data is then transferred from the source storage device through the Virtual Storage Server to the one or more destination storage devices. Because data is transferred only in amounts that the destination is ready to receive, the Virtual Storage Server does not need a large buffer, and can basically send data received at wire speed. This process continues until the amount of data in the write command is transferred to the one or more destination storage devices.

Cycle independent data to echo clock tracking circuit
InactiveUS6134182AAvoid dataDigital storageGenerating/distributing signalsDouble data rateData signal
A comparator and variable delay circuit are provided to maintain the tracking between data and echo clocks in a double data rate (DDR)RAM device. This is accomplished by providing a global data signal (dummy data signal) that tracks with the actual memory array data. This global data signal is compared to the timing of the RAM clock (CLOCK) to determine a delay time between the two by which the pipeline clocks (CLKRISE / CLKFALL) must be delayed. As a result, the pipeline clocks are pushed out as needed so that they always transition after the array data arrives at the output latch. Therefore, as cycle time decreases, both echo clocks and data are pushed out identically and maintain their required tracking.
