Detecting duplicate and near-duplicate files

Improved duplicate and near-duplicate detection techniques may assign a number of fingerprints to a given document by (i) extracting parts from the document, (ii) assigning the extracted parts to one or more of a predetermined number of lists, and (iii) generating a fingerprint from each of the populated lists. Two documents may be considered to be near-duplicates if any one of their fingerprints match.

Monitoring fitness using a mobile device

Athletic performance monitoring and tracking may provide multiple ways in which to track athletic movement and activity. In one example, an athletic monitoring device may include or be associated with multiple types of movement sensors and switch between the sensors or use both depending on various factors including type of workout. Workouts may also be tagged with various parameters including mood, weather, terrain, athletic equipment used and the like. In one or more examples, the parameters may be automatically determined based on location. User workouts and accomplishments may also be celebrated through messages from celebrities, family, friends and other users. In some cases, the messages may be triggered by various conditions. Coaching may also be provided to the user to help improve workouts and overall athletic performance. Running routes may also be automatically tracked, stored and shared.

Efficient backups using dynamically shared storage pools in peer-to-peer networks

A system for efficient backups using dynamically shared storage pools in peer-to-peer networks comprises one or more processors and memory coupled to the processors. The memory stores instructions executable by the processors to implement a backup manager configured to dynamically subdivide a storage pool into one or more portions of storage currently designated for local backup data and one or more portions of storage currently designated for peer-to-peer (P2P) backup data. In response to local backup data received from a backup client, the backup manager may store the local backup data in a portion of the storage pool that is currently designated for local backup data. The backup manager may then generate a P2P version of the local backup data, e.g., by encrypting and / or redundancy encoding the local backup data, and transmit parts of the P2P version to each of one or more peer devices in the P2P network.

System and method for parallel execution of data generation tasks

A CPU module includes a host element configured to perform a high-level host-related task, and one or more data-generating processing elements configured to perform a data-generating task associated with the high-level host-related task. Each data-generating processing element includes logic configured to receive input data, and logic configured to process the input data to produce output data. The amount of output data is greater than an amount of input data, and the ratio of the amount of input data to the amount of output data defines a decompression ratio. In one implementation, the high-level host-related task performed by the host element pertains to a high-level graphics processing task, and the data-generating task pertains to the generation of geometry data (such as triangle vertices) for use within the high-level graphics processing task. The CPU module can transfer the output data to a GPU module via at least one locked set of a cache memory. The GPU retrieves the output data from the locked set, and periodically forwards a tail pointer to a cacheable location within the data-generating elements that informs the data-generating elements of its progress in retrieving the output data.

Short-range wireless system and method for multimedia tags

A short-range wireless system and method is disclosed to store and transfer a new type of multimedia data construct called a tag. A user can write text, create a voice clip and append it to the text, take a digital picture and append it to the text, to create a multimedia file as the content of a tag. The creation or modifying of the multimedia file can be done in the user's mobile wireless device or off line and then stored in the mobile device. The multimedia file is then incorporated into the tag or it can be referenced by a pointer in the tag. The multimedia file is artistic expression of the user and the tag uniquely associates the user's identity with the multimedia file by prohibiting alteration of the content after the user completes its creation. A content-originator flag (CFG) value in the tag is set to “false” during the period when the user is creating or modifying the tag's content. When the user completes editing the content of the tag, the content-originator flag (CFG) value is set to true, thereby freezing the content. The tag includes the user's ID, such as his / her international mobile subscriber identity (IMSI) or mobile station ISDN number (MSISDN). Subsequent viewers of the content can make a copy of the content and can then modify it, but they cannot authentically attribute the modified copy to the original user. The system can be implemented as a wireless personal area network (PAN) such as provided in the Bluetooth Standard or a wireless local area network (LAN) such as provided in the IEEE 802.11 Wireless LAN Standard and the HIPERLAN Standard.

Apparatus and method for validating a database record before applying journal data

An apparatus and method includes a database journal that records journal entries. Each journal entry includes a validation value that is computed from the data and metadata for the record before it is changed. In this manner, journal entries may be applied with confidence to a record in a database. This is especially useful when minimized data journal entries are used. If the validation value of the journal entry matches the validation value computed from the data and metadata of the record that the journal entry is to be applied to, then the record before applying the journal entry is identical to the record in the original database, and the journal data may be applied to the database record. If the validation value of the journal entry does not match the validation value computed from the data and metadata of the record that the journal entry is to be applied to, the record is not the same as in the original database when the journal entry was generated. As a result, an error message is generated to indicate that an error was encountered when applying the journal entry. In this manner, the apparatus and method of the preferred embodiments automatically validate a database record before applying journal data to the record.

Test probability density histograms of ΔRRs of the patient are constructed from the detected RR intervals. Finally, the standard and test histograms are compared to detect whether the patient suffers from cardiac arrhythmia. As non limiting examples, the standard probability density histograms of ΔRRs are modeled by a mathematical equation selected from the group consisting of: the Lorentzian distribution, the Gaussian distribution, the Student's t-distribution, and a probability distribution including a linear combination of the Lorentzian and Gaussian distribution.

System and Method for Generating 2D Texture Coordinates for 3D Meshed Surfaces

Systems and methods for generating 2D texture coordinates for 3D surfaces meshes may assign initial 2D texture coordinates to each node within a mesh using dead reckoning, compute a conformal mapping solution to revise the texture coordinates dependent on the initial mapping, and store the texture coordinates for subsequent use in a graphics application (e.g., applying a texture and / or re-meshing a surface). The methods may include designating one node as the origin, determining the shortest distance from each other node to the origin, and computing texture coordinates for each other node in order of increasing distance to the origin. The dead reckoning operation may compute texture coordinates of each node dependent on the distance and direction of a vector formed between the node and a neighbor node to which texture coordinates have already been assigned. Isometric terms reflecting stretching or compression may be introduced following convergence by the conformal mapping.
