20090142512APPARATUS AND METHOD FOR DEPOSITING ELECTRICALLY CONDUCTIVE PASTING MATERIAL - A method and apparatus are described for reducing particle contamination in a plasma processing chamber. In one embodiment, a pasting disk is provided which includes a disk-shaped base of high-resistivity material that has an electrically conductive pasting material layer applied to a top surface of the base so that the pasting material layer partially covers the top surface of the base. The pasting disk is sputter etched to deposit conductive pasting material over a wide area on the interior surfaces of a plasma processing chamber while minimizing deposition on dielectric components that are used to optimize the sputter etch process during substrate processing.06-04-2009

20100243440Mechanism for continuously varying radial position of a magnetron - A continuously variable multi-position magnetron that is rotated about a central axis in back of a sputtering target at a freely selected radius. The position is dynamically controlled from the outside, for example, through a hydraulic actuator connected between a pivoting arm supporting the magnetron and an arm fixed to the shaft, by two coaxial shafts independent controllable from the outside and supporting the magnetron through a frog-leg mechanism, or a cable connected between the pivoting arms and moved by an external slider. The magnetron can be rotated at two, three, or more discrete radii or be moved in a continuous spiral pattern.09-30-2010

20110004729Block Caching for Cache-Coherent Distributed Shared Memory - Methods, apparatuses, and systems directed to the caching of blocks of lines of memory in a cache-coherent, distributed shared memory system. Block caches used in conjunction with line caches can be used to store more data with less tag memory space compared to the use of line caches alone and can therefore reduce memory requirements. In one particular embodiment, the present invention manages this caching using a DSM-management chip, after the allocation of the blocks by software, such as a hypervisor. An example embodiment provides processing relating to block caches in cache-coherent distributed shared memory.01-06-2011

20090006297OPEN-WORLD MODELING - The claimed subject matter provides systems and/or methods that facilitate generating an inference about events that may not have yet been observed. Open-world modeling can be used to take a history of observation so as to understand trends over time in the revelation of previously unseen events, and to make inferences with subsets of data that new unseen events will be seen. Thus, inaccuracies associated with predictions generated from incomplete data sets can be mitigated. To yield such predictions, open-world submodels and closed-world submodels that do not allow for previously unseen events can be combined via a model mixture methodology, which fuses inferences from the open- and close-world models.01-01-2009
20090006574SYSTEM AND METHODS FOR DISRUPTION DETECTION, MANAGEMENT, AND RECOVERY - A task disruption and recovery system and methods are described that detects shifts away from ongoing tasks, whether by self-interruption or by disruptive events from within or outside a computing system, based on signals detected. Among other functions, the system works to enhance the efficient recovery of suspended tasks or problem-solving sessions via storing and presenting representations of the suspended sessions in a manner that facilitates recovery and continuation.01-01-2009
20100075639COMPUTING AND HARNESSING INFERENCES ABOUT THE TIMING, DURATION, AND NATURE OF MOTION AND CESSATION OF MOTION WITH APPLICATIONS TO MOBILE COMPUTING AND COMMUNICATIONS - An information delivery system comprises a receiver component that receives information about the movement, velocity, acceleration, and/or locations over time of a user. A computation component using a predictive model generates a probability distribution relating to one or more of when the user will next be stopped, how long the user will be stopped, how long a pattern of motion, such as walking, driving in stop and go traffic, and smooth highway motion will last, based at least in part upon signals about motion over time. The system can further comprise an alerting component that determines when to provide the user with information based at least in part upon the probability distribution over some aspect of motion or cessation of motion, and optionally the content, or tagged or inferred urgency or importance, of a message or communication.03-25-2010
20100269051STATISTICAL MODELS AND METHODS TO SUPPORT THE PERSONALIZATION OF APPLICATIONS AND SERVICES VIA CONSIDERATION OF PREFERENCE ENCODINGS OF A COMMUNITY OF USERS - A statistical methodology is employed for assisting people with the setting of parameters of software applications or services. With the method, information about demographics and/or about the complete or partial preferences of other people, are analyzed to infer recommendations for settings and functionality of a computer application or service. A system is reviewed with the ability to receive data regarding a plurality of users, and stores respective profiles for these users in a community store. The system can leverage off of these completed and/or partially completed profiles of parameters representing preferences about software operation in connection with building new profiles for users (new and/or existing). Data regarding a user that desires to build a new profile is employed in connection with the community profiles to facilitate the user building a personalized profile. Various statistical and/probabilistic schemes can be employed, for example, collaborative filtering techniques to identify to the user the top n settings by particular parameter(s), top m settings by popularity, top x most similar profiles to facilitate the user selecting most appropriate sub-profiles as part of a personalized profile building and selection effort.10-21-2010

20110066591POLICY-BASED STORAGE STRUCTURE DISTRIBUTION - Policy-based storage and retrieval combined with a distribution algorithm results in automatic and even distribution of policy-based storage structures across a set of nodes and dynamic, automated homing or ownership of policy-based storage structures. Large numbers of policy-based storage structures may be distributed without manual administration, allowing for rapid creation and destruction of storage structures. The overall load may be distributed and balanced across the server pool. Multiple entries having the same key value in a database- or table-like structure allow for distribution of policy-based storage and retrieval by key value and for queue semantics to be utilized for microqueues in the large database- or table-like structure.03-17-2011
