摘要： 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.

摘要： 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.

摘要： An image sensor communicates with a microcontroller. A capture timing circuit provides feedback from the microcontroller to the image sensor. The microcontroller bidirectionally communicates with a memory subsystem and a communication interface. A “background learning” technique is applied to the captured images to determine when motion activity has occurred.

摘要： In a device, one or more low energy sensors are used to determine a mobility state of the device. Based on both the mobility state of the device and one or more places of interest for the device, a determination is made as to when to use a high energy sensor to determine a location of the device. One of the one or more places of interest for the device within which the device is located at any particular time can be determined based on the mobility state of the device and/or the location of the device as determined by the high energy sensor.

摘要： 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.

摘要： The subject disclosure is directed towards a technology by which a computing device user may share context-related information (e.g., including current activity) with other recipient machines. A requestor may request to peek at a user's context, and if the requestor is valid (pre-approved by the user), a response based on context-related information is sent, which may be via a cloud service. The response may be filtered and/or adjusted based upon the identity of the requestor and other information associated with that identity, e.g., filtering criteria set by the user. Also described is notifying the user of the peek request, and logging information corresponding to the request and response. A broadcast message may also be sent by the device to share context without waiting for a peek request.

摘要： An implementation of location estimation using image analysis is described. In this implementation, an image of a place is obtained and matched with previously stored images. The matching may be achieved by employing methods based on key feature extraction algorithm, color histogram analysis, pattern matching or other image comparison techniques. Upon determining a match, the location information associated with the image provides the location. The location information may be in the form of location tags or location keywords and the location information may be used by the user or other applications for the purposes of location determination. The technique allows for the user to enter location information. The location information may be assigned to the previously stored images residing in local and remote databases for users and applications to assign information or keywords to images.
