Abstract: Techniques for efficient access to flash databases are described. In one implementation, a method includes performing an operation on a flash database, supplementing at least one portion of a node translation table corresponding to at least one node involved in the operation, and semantically compressing at least one portion of the node translation table. The semantic compression includes discarding at least one log entry that is rendered obsolete by at least one subsequent log entry, and incrementing a version number of the log entries corresponding to the at least one portion of the node translation table. In further embodiments, discarding at least one log entry includes discarding at least one log entry that is at least one of opposed by or overruled by at least one subsequent log entry.

Abstract: One or more computers manage power consumption in a plurality of computers by repeatedly evaluating power consumption of pluralities of computers such that any given plurality of computers is evaluated by aggregating indicia of power consumption of the individual computers in the given plurality. The evaluation identifies or predicts pluralities of computers that are over-consuming power and identifies pluralities of computers that are under-consuming power. A first plurality of computers identified as over-consuming power are sent messages to instruct some of its comprising computers or virtual machines (VMs) to lower their computational workload. A second plurality of computers identified as under-consuming power are sent messages instructing the other computers to increase their computation workload.

Abstract: Embodiments of the virtual machine power metering system and method measure the power consumption of individual virtual machines. Power meter measurements for a physical host server are converted into individual virtual machine power meters that measure the power consumption of each individual virtual machine residing on the host server. The virtual machine power consumption is computed by generating a power model using the total power consumption of the host server and resource utilization for a virtual machine. Optimal power model coefficients are computed using the power model. The energy used by the virtual machine is computed using one of two embodiments. Embodiments of the system and method also can be used to obtain the power consumption for a specific activity (such as a service, request, or search query). In addition, the virtual machine power metering can be used for virtual machine power capping to allow power oversubscription in virtualized environments.

Abstract: Meeting information is collected in an automatic or automated manner utilizing user devices among other devices likely to be present at meetings. Devices can detect the occurrence of a meeting and initiate data capture. Subsequently, aggregated data can be processed to facilitate access and/or dissemination of the data. For instance, data can be contextualized and/or indexed. Further, data can be generated in or converted to forms more suitable for information distribution (e.g., summary, points of interest . . . ).

Abstract: A method for pixel extraction and replacement is disclosed. In one implementation, the method includes generating a set of pixel values and pixel value frequencies for a pixel presented in a series of digital images of a scene. A digital image of the scene which includes a pixel value for the pixel is received and a comparison is made between the pixel value and the set of pixel values. A determination is performed to decide upon substitution of the pixel value with a different pixel value based on the comparison. Other techniques are also disclosed.

Abstract: Image text enhancement techniques are described. In an implementation, graphically represented text included in an original image is converted into process capable text. The process capable text may be used to generate a text image which may replace the original text to enhance the image. In further implementations the process capable text may be translated from a first language to a second language for inclusion in the enhanced image.

Abstract: Implementations of coverage-based image relevance ranking are described. In one implementation, an acquired image is ranked relative to a set of previously stored images based upon the conditional entropy of the acquired image. The conditional entropy may be computed after first removing overlapping pixels that are present in both the acquired image and the set of previously stored images. Once the image is assigned a relevance rank, other decisions concerning the image may be made based on the rank, such as whether to save the image, delete the image, or use it to replace a less relevant image.

Abstract: Techniques for self-tuning indices for databases, including flash-based databases, are described. Using a data tree structure wherein the nodes of the data tree may operate in two modes (e.g. disk mode or log mode), a self-tuning index determines whether it is more economical to perform a requested operation on a node in its current mode or in an alternate mode. The operation is then performed on the node using the more economical mode.

The method further includes the act of requesting that the mobile computing device transmit a data packet to the computing device based at least in part upon the value of information for obtaining data from the personal sensor of the user.

Abstract: Recovery is expedited for crashes involving flash memory. Rather than requiring an entire flash memory to be read to reconstruct lost information, only a subset of the memory need be read thereby reducing system down time, among other things. In particular, state information such as a logical to physical mapping is captured via a checkpoint operation periodically. Moreover, a deterministic usage pattern is employed to facilitate recovery of actions performed after a checkpoint.

The system further includes a selector component that selects the at least one sensor from amongst a plurality of sensors based at least in part upon the value of information and the preferences. The determination of the value ascribed to sensors may include considerations of the utilitarian benefit of reduction of uncertainty to a population of people.
