20100070784 | Reducing Power Consumption in a Server Cluster - A method of reducing power consumption of a server cluster of host systems with virtual machines executing on the host systems is disclosed. The method includes recommending host system power-on when there is a host system whose utilization is above a target utilization, and recommending host system power-off when there is a host system whose utilization is below the target utilization. Recommending host system power-on includes calculating impact of powering on a standby host system with respect to reducing the number of highly-utilized host systems in the server cluster. The impact of powering on is calculated by simulating moving some virtual machines from highly utilized host systems to the standby host system being recommended to be powered on. Recommending host system power-off includes calculating impact of powering off a host system with respect to decreasing the number of less-utilized host systems in the server cluster. The impact of powering off is calculated by simulating moving all virtual machines from the host system, which is being recommended to be powered-off, to less-utilized host systems. | 03-18-2010 |

20120078923 | SCRIPTING USING NEW ORDERING ALGORITHM - Ordering data objects. The method includes, for each object to be ordered into a set of ordered objects, determining whether the object has static dependencies or dynamic dependencies. A dynamic object is an object that may have circular dependencies. For each static object with only static dependencies, the objects are ordered according to a pre-determined type order. The method further includes, for one or more dynamic objects with dynamic possibly circular dependencies, resolving the circular dependencies such that the dynamic objects can be ordered with the static objects. | 03-29-2012 |

20090125570 | Online backup and restore - Online backup of image files includes providing a user interface for making a backup selection based on an image catalog that includes a plurality of image files, the user interface including a resolution option; receiving a backup selection based on the image catalog, the backup selection indicating a selection of an image file in the image catalog and a resolution choice associated with the image file; and sending a copy of the image file to a remote storage, the copy having a resolution that corresponds to the resolution choice. | 05-14-2009 |
20130114894 | Blending of Exposure-Bracketed Images Using Weight Distribution Functions - Systems and methods are presented for generating a new digital output image by blending a plurality of digital input images capturing the same scene at different levels of exposure. Each new pixel for the new digital output image is derived from a group of corresponding aligned pixels from the digital input images. In order to determine a weight for each pixel in each group of mutually-aligned source-image pixels, a weight distribution function is applied to values of an image characteristic for the pixels in the group of corresponding aligned pixels, and a net weight is subsequently assigned to each of the pixels in the group. Pixel values of pixels in each group of mutually-aligned source-image pixels are modified based on the net weights assigned to the pixels in order to obtain a new pixel value for a corresponding new pixel in the new digital output image. | 05-09-2013 |
