| 20110099551 | Opportunistically Scheduling and Adjusting Time Slices - Computerized methods, computer systems, and computer-readable media for governing how virtual processors are scheduled to particular logical processors are provided. A scheduler is employed to balance a load imposed by virtual machines, each having a plurality of virtual processors, across various logical processors (comprising a physical machine) that are running threads in parallel. The threads are issued by the virtual processors and often cause spin waits that inefficiently consume capacity of the logical processors that are executing the threads. Upon detecting a spin-wait state of the logical processor(s), the scheduler will opportunistically grant time-slice extensions to virtual processors that are running a critical section of code, thus, mitigating performance loss on the front end. Also, the scheduler will mitigate performance loss on the back end by opportunistically de-scheduling then rescheduling a virtual machine in a spin-wait state to render the logical processor(s) available for other work in the interim. | 04-28-2011 |

| 20100106930 | OPPORTUNISTIC PAGE LARGIFICATION - Page tables in the last level of a hierarchical page table system are scanned for candidate page tables. Candidate page tables are converted to large pages, having a page table entry in a level before the last level of the hierarchical page table system adjusted to be associated with the newly created large page. Upon receiving a notification that a large page is to be converted into a page table, a new page table is created. Each entry in the new page table is associated with a small segment of memory in the large page and an entry in a page table one level before the last level in a hierarchical page table system is adjusted to be associated with the new page table. | 04-29-2010 |

| 20100134309 | METHOD AND SYSTEM FOR LOCATING SIGNAL EMITTERS USING CROSS-CORRELATION OF RECEIVED SIGNAL STRENGTHS - A method and system for determining a location of a first device that emits a signal: provide at least three sensors separated and spaced apart from each other; at each of the sensors, receive the signal emitted by the first device; determine the received signals for each of the sensors; determine cross-correlations of the received signals for pairs of the sensors; and determine the location of the first device from the magnitudes of the cross-correlations of the received signals. | 06-03-2010 |
| 20100138184 | Likelihood Map System for Localizing an Emitter - A system and a method for displaying an emitter location are disclosed. The system includes a plurality of receivers at different locations in a field. Each receiver generates a receiver signal that depends on the magnitude of a signal from the emitter. The system also includes a processor that receives the receiver signal and generates a likelihood map indicative of an approximation of a probability as a function of position in the field of the emitter location. The likelihood map includes a plurality of receiver maps. Each receiver map includes a probability as a function of position in the field of the emitter location based on the signal magnitude for at least one of the receiver signals. Each receiver map may depend on a ratio of the signal magnitudes from a corresponding pair of the receivers, or on one of the signal magnitudes from a corresponding one of the receivers. | 06-03-2010 |

| 20090003309 | CAPABILITY OR ROLE-BASED ROUTING - The claimed subject matter provides a system and/or a method that facilitates enhancing incoming data communication connectivity within a network. An analyzer component can evaluate a portion of an incoming data communication targeted for a network to identify a context associated with the data communication. A transfer component can direct the incoming data communication to a cluster within the network based at least in part upon the identified context, wherein the cluster includes a physical entity with pre-existing knowledge of the identified context. | 01-01-2009 |
| 20090003569 | VIRTUAL CONTACT IDENTIFIER - The claimed subject matter provides a system and/or a method that facilitates enhancing connectivity associated with data communications. An interface can receive a portion of communication state data, wherein the communication state data is related to at least one of a data communication mode and a user context state. A routing component can evaluate the portion of communication state data to identify an optimized data communication mode, wherein the optimized data communication mode is dynamically linked to a virtual contact identifier. Moreover, the routing component can automatically and seamlessly employ an optimized communication session utilizing the dynamically identified optimized data communication mode based upon an activation of the virtual contact identifier. | 01-01-2009 |

| 20090046139 | SYSTEM AND METHOD FOR DISTRIBUTED MEETINGS - A system and method for teleconferencing and recording of meetings. The system uses a variety of capture devices (a novel 360° camera, a whiteboard camera, a presenter view camera, a remote view camera, and a microphone array) to provide a rich experience for people who want to participate in a meeting from a distance. The system is also combined with speaker clustering, spatial indexing, and time compression to provide a rich experience for people who miss a meeting and want to watch it afterward. | 02-19-2009 |

| 20090323981 | Satellite Microphone Array For Video Conferencing - Speakers are identified based on sound origination detection through use of infrared detection of satellite microphones, estimation of distance between satellite microphones and base unit utilizing captured audio, and/or estimation of satellite microphone orientation utilizing captured audio. Multiple sound source localization results are combined to enhance sound source localization and/or active speaker detection accuracy. | 12-31-2009 |

| 20100039497 | SATELLITE MICROPHONES FOR IMPROVED SPEAKER DETECTION AND ZOOM - Architecture for exploiting satellite microphones and employing other techniques of conference room camera/microphone systems to significantly improve the true positive rate (reduce false positives) in sound source localization (SSL). Techniques for realizing the improvement include using an LED emitter to determine the precise location of the satellite microphones on a table, using the base SSL and external sounds to determine the approximate location of the satellite microphone on the table, using the satellite microphone phase to improve the SSL performance, using the satellite microphone amplitude to improve the active speaker detector (ASD) performance, and using the satellite microphones to estimate camera zoom. | 02-18-2010 |
| 20100322387 | ENDPOINT ECHO DETECTION - Architecture that employs a signal (e.g., audible or inaudible sounds) to detect if endpoints of a communications session are sufficiently close to each other to induce echo, and then control (e.g., muting) is applied to one or more of the endpoints to prevent echo. The signals can be played and detected from the endpoints or a central conferencing component such as a multiple control unit (MCU). The MCU can provide support for legacy endpoints as well. When echo is detected, the offending endpoint(s) can be controlled to mute one or more onboard devices such as a speaker or microphone. The device(s) can be muted from a remote component or for a local component or locally by the endpoint user. A notification can be sent that notifies the endpoint user that the mute operation has been applied or should be applied to one or more of the local devices. | 12-23-2010 |
| 20100324891 | MUTE CONTROL IN AUDIO ENDPOINTS - Architecture that uses near-end speech detection and far-end energy level detection to notify a user when a local microphone and/or speaker that the user is using, are muted. A voice activity detector is employed to detect the presence of near-end speech, sense the existing mute state of the near-end microphone, and then notify the user when the current microphone is muted. Separately or in combination therewith, received far-end voice signals are detected, the associated energy level computed, the existing mute state of the near-end audio speaker is sensed, and the user notified when the speaker is muted and/or at a reduced volume setting. These determinations enhance the user experience when the architecture is employed for communications sessions where participants connect via different communications modalities by automatically notifying the user of the audio device state, without attempting to contribute only to find that a microphone or speaker was muted. | 12-23-2010 |
