| 20090281783 | DEVICE, SYSTEM, AND METHOD OF STORAGE CONTROLLER SIMULATING DATA MIRRORING - Device, system, and method of storage controller simulating data mirroring. For example, an apparatus for simulating data mirroring includes: a storage controller to control a primary storage unit that has data stored therein, wherein the storage controller is able to simulate a process of mirroring data stored in the primary storage unit in response to a mirroring simulation command. | 11-12-2009 |
| 20090281782 | DEVICE, SYSTEM, AND METHOD OF STORAGE CONTROLLER HAVING SIMULATED VOLUMES - Device, system, and method of storage controller having simulated volumes. For example, an apparatus for data storage management includes: a storage controller to manage access to one or more physical volumes, the storage controller including a simulation module to simulate access to one or more simulated volumes. | 11-12-2009 |
| 20090281743 | MANAGING ENERGY USAGE BY DEVICES ASSOCIATED WITH A VIRTUAL UNIVERSE RESOURCE CONSERVATION - A virtual universe can include regions that conserve natural resource usage. A virtual universe natural resource conservation system can determine a measure of comprehensive energy usage of a plurality of devices associated with a controlled energy use region in a virtual universe. The system can determine that the measure of comprehensive energy usage approaches a usage threshold for the controlled energy use region. The system can also impose one or more conservation limitations on at least one of the plurality of devices to maintain the comprehensive energy usage within the usage threshold. | 11-12-2009 |
| 20080256031 | Method and Apparatus for Ranking-Based Information Processing - Techniques are provided for ranking-based information processing. Method steps can include integrating information from at least one source (a plurality of heterogeneous sources can also be handled), to obtain integrated information; mapping the integrated information to at least one application; ranking the integrated information based on the mapping and on ranking criteria from a knowledge base; and processing the integrated information, based on the ranking, to obtain processed integrated information. Optionally, the processing step includes formatting the processed integrated information for a plurality of applications. | 10-16-2008 |
| 20080212824 | Protecting images with an image watermark - A robust means of watermarking a digitized image with a highly random sequence of pixel brightness multipliers is presented. The random sequence is formed from ‘robust-watermarking-parameters’ selected and known only by the marker and/or the marking entity. A watermarking plane is generated which has an element array with one-to-one element correspondence to the pixels of the digitized image being marked. Each element of the watermarking plane is assigned a random value dependent upon a robust random sequence and a specified brightness modulation strength. The so generated watermarking plane is imparted onto the digitized image by multiplying the brightness value or values of each pixel by its corresponding element value in the watermarking plane. The resulting modified brightness values impart the random and relatively invisible watermark onto the digitized image. Brightness alteration is the essence of watermark imparting. Detection of an imparted watermark requires knowing the watermarking plane with which the watermark was imparted. Regeneration of the watermarking plane requires knowledge of the robust-marking-parameters used in its formulation. This is generally only known to the marker and/or marking entity. Once regenerated the watermarking plane is used together with a verifying image located in a ‘visualizer’ to demonstrate the existence of the watermark. | 09-04-2008 |
