A computing device having an optimized file system and methods for use therein. File system optimizations include sector-aligned writes, anchored cluster searches, anchored index searches, companion caches dedicated to particular file management data types and predictive cache updates, all of which expedite processing on the computing device. The file system optimizations are especially advantageous for data collection systems where an embedded device is tasked with logging to a target memory data received in a continuous data stream and where none of the streamed data is deleted until after the target memory has been offloaded to another device.

Computing device having optimized file system and methods for use therein

Automatic recovery from loss of a security token on an embedded device is achieved by having a service provider (SP) server send to a device server a backup copy of the security token in conjunction with sending to an embedded device a primary copy of the security token, and retrieving from the device server and sending to the embedded device the backup copy of the security token upon detecting that the primary copy of the security token has been lost. The method and system obviate the need for a user to have to re-input on the embedded device a credential that is represented by the security token in the event the primary copy of the security token is erased from the embedded device or otherwise becomes inaccessible to the embedded device.

With a growing number of personal and shared devices that may be connected to the Internet, the number of devices on which a person may receive a message increases. Privacy in message delivery may become an issue when a message may be received on a shared device, for example, a television. Aspects of the present invention relate to systems and methods for displaying message alerts on shared and private devices according to user preferences.

Methods and systems for message-alert display

With the growing number of, both personal and shared, devices that may be connected to the Internet, the number of possible media sources that may provide input for a message increases, as does the complexity of message preparation. Additionally, with the introduction of shared devices, such as televisions, as media sources for messages, both authentication and security issues are of fundamental importance. Aspects the present invention are related to systems and methods for combining media inputs at an external, central server for messaging.

Methods and systems for combining media inputs for messaging

A system for coding images, and more particularly, to a system for compressing images to a reduced number of bits by employing a Discrete Cosine Transform (DCT) in combination with a visual model.

Image compression using a color visual model

Embodiments of the present invention provide systems and methods for managing and transmitting image data. Some embodiments are particularly suited to streaming JPEG 2000 images from a web server.

Methods and systems for scalable streaming of images with client-side control

Method and apparatus for use in Huffman decoding are described. In exemplary systems, a JPEG Huffman decoder is capable of simultaneously decoding multiple coefficients and/or symbols in a single table lookup. Methods for designing, building, and using such a table are included. Other embodiments are described and claimed.

Multi-symbol/coefficient decode operation for Huffman codes

A method of decompressing image data, includes reception of a VQ encoded image. The received image is decoded. Output image color space processing is performed in combination with the decoding as one process. Output image color space processing may include color transformation, half-toning or both. The resulting output image has been both decoded and transformed in color space.

Method for combining vector-quantization decoding with color transform or halftoning or both

A method for data compression. An encoder receives data vectors from an original data set. The encoder uses a vector quantization codebook to encode the data vectors into encoded vectors. The codebook is constructed from a compound data set, where the compound data set includes real data vectors and artificial data vectors. The encoded vectors are indexed in the codebook and the indexes are transmitted across communication channels or transmitted to storage.
