  • LOCAL IMAGE ENHANCEMENT FOR TEXT RECOGNITION
    Publication number: 20140270528
    Abstract: Various embodiments enable regions of text to be identified in an image captured by a camera of a computing device for preprocessing before being analyzed by a visual recognition engine. For example, each of the identified regions can be analyzed or tested to determine whether a respective region contains a quality associated with poor text recognition results, such as poor contrast, blur, noise, and the like, which can be measured by one or more algorithms. Upon identifying a region with such a quality, an image quality enhancement can be automatically applied to the respective region without user instruction or intervention. Accordingly, once each region has been cleared of the quality associated with poor recognition, the regions of text can be processed with a visual recognition algorithm or engine.

  • EFFICIENT QUERY PROCESSING USING HISTOGRAMS IN A COLUMNAR DATABASE
    Publication number: 20140201129
    Abstract: A probabilistic data structure is generated for efficient query processing using a histogram for unsorted data in a column of a columnar database. A bucket range size is determined for multiples buckets of a histogram of a column in a columnar database table. In at least some embodiments, the histogram may be a height-balanced histogram. A probabilistic data structure is generated to indicate for which particular buckets in the histogram there is a data value stored in the data block. When an indication of a query directed to the column for select data is received, the probabilistic data structure for each of the data blocks storing data for the column may be examined to determine particular ones of the data blocks which do not need to be read in order to service the query for the select data.

  • GESTURE DETECTION MANAGEMENT FOR AN ELECTRONIC DEVICE
    Publication number: 20140149754
    Abstract: The amount of power and processing capacity needed to process gesture input for a computing device is reduced by splitting the management of sensors, used to detect the input, among different processing components. A relatively high power processor system can monitor the sensors and determine the presence of gestures when the device is in an active state. When the device, or at least the processor system, enters a sleep mode, sensor management is transferred to a microcontroller connected to at least a portion of the sensors, such that the microcontroller can analyze the sensor data to determine the likelihood of a wake action being performed. In response to detecting a wake action, the microcontroller can contact a component such as a power management component to place the processor system in an active state, and enable the processor system to resume management of the sensors.

  • Dynamically Updating an Electronic Paper Display by Computational Modeling
    Publication number: 20140176614
    Abstract: Embodiments provide techniques for updating pixels of an electrophoretic display through computational modeling of a current state of each pixel. A model buffer may store data for a modeled current state of each pixel in a display, providing a prediction of a current color state for each pixel based on voltages previously applied to the pixel. Upon receiving a frame to be displayed, including a target state for each pixel, embodiments determine which of a set of voltages (e.g., positive, negative, or neural/zero voltages) optimally alters the state of the pixel to be as close as possible to the target state. These voltage(s) may be applied to each pixel in an iterative manner, with each voltage determined based on the current modeled state of the pixel.

  • CONNECTION PUBLISHING IN A DISTRIBUTED LOAD BALANCER
    Publication number: 20140310417
    Abstract: A connection publishing method for a distributed load balancer in which a router receives packets from at least one client and routes packet flows to multiple load balancer (LB) nodes, which in turn distribute the packet flows among multiple server nodes. A load balancer (LB) module on each server node determines and publishes a list of active connections between client(s) and the server (a connection publishing packet) back to the LB nodes. The LB module may randomly select a LB node to receive the packet. Upon receiving the packet, the LB node processes the connection information in the packet, distributing the connection information among appropriate LB nodes. Receiving the connection publishing information from the server nodes refreshes leases for the connections on the LB nodes.

  • COMMUNICATION BETWEEN APPLICATION COMPONENTS DISTRIBUTED AMONG DEVICES
    Publication number: 20140214918
    Abstract: Disclosed are various embodiments for facilitating communications between application components that are distributed among many devices across a network. This allows for the application to execute as if on one device even though the application components are on many devices. A component interface is generated for the application components. The component interface intercepts communications sent from an application component, locates the intended receiving application component, and generates a component interface packet with the location. The component interface packet is then put into a network stream. The receiving component listens to the stream to obtain component interface packets that indicate the location of the device running the receiving application component. The component interface decodes the component interface packets intended for components associated with the component interface and sends communications encoded in the packet to the application components.

  • SPEECH MODEL RETRIEVAL IN DISTRIBUTED SPEECH RECOGNITION SYSTEMS
    Publication number: 20140163977
    Abstract: Features are disclosed for managing the use of speech recognition models and data in automated speech recognition systems. Models and data may be retrieved asynchronously and used as they are received or after an utterance is initially processed with more general or different models. Once received, the models and statistics can be cached. Statistics needed to update models and data may also be retrieved asynchronously so that it may be used to update the models and data as it becomes available. The updated models and data may be immediately used to re-process an utterance, or saved for use in processing subsequently received utterances. User interactions with the automated speech recognition system may be tracked in order to predict when a user is likely to utilize the system. Models and data may be pre-cached based on such predictions.
