Abstract: A environmental reproduction system multiplexes information from a variety of sources to reproduce a target environment having visual and/or auditory impediments. The visual impediments may include one or more environmental conditions, such as rain, sleet, snow, darkness, brightness, or any other type of environmental condition. The auditory impediments may include loud noises, such as construction noises, or sounds that are too low, such as an emergency vehicle sound not being heard. The environmental reproduction system may determine the environmental condition from one or more sources, such as an internal microphone, an external microphone, temperature sensor, a camera, a weather receiver, or other types of sensors. The environmental reproduction may be in communication with an environmental condition database and operative to apply a signal processing action to a recording (video and/or audio recording) of the target environment based on the determined environmental condition.

Abstract: A system and machine-implemented method for presenting profile information on an electronic device of a user, the profile information being associated with a contact of the user, via displaying a contact icon on a graphical user interface of the electronic device, the contact icon corresponding to a contact of the user; receiving user input which specifies selection of the contact icon; and displaying profile information, obtained from a profile associated with the contact corresponding to the selected contact icon, on the graphical user interface.

Abstract: In general, the subject matter described in this specification can be embodied in methods systems, and program products for determining a change in a mode of transportation. A change in a mode of transportation of the mobile computing device may be determined by determining that a speed of the mobile computing device has changed. A first geographical location is stored as a geographical location of the mobile computing device that corresponds to the change in mode of transportation. A graphical indication of the first geographical location is displayed. The graphical indication of the first geographical location is different than graphical indications for one or more other geographical locations of the mobile computing device at one or more other times. The one or more other geographical locations were not determined to correspond to a change in mode of transportation.

Abstract: Various mechanisms are disclosed for improving the operational efficiency of a virtual translation look-aside buffer (TLB) in a virtual machine environment. For example, one mechanism fills in entries in a shadow page table (SPT) and additionally, speculatively fills in other entries in the SPT based on various heuristics. Another mechanism allows virtual TLBs (translation look-aside buffers) to cache partial walks in a guest page table tree. Still another mechanism allows for dynamic resizing of the virtual TLB to optimize for run-time characteristics of active workloads. Still another mechanism allows virtual machine monitors (VMMs) to support legacy and enlightened modes of virtual TLB operation. Finally, another mechanism allows the VMM to remove only the stale entries in SPTs when linking or switching address spaces. All these mechanisms, together or in part, increase the operational efficiency of the virtual TLB.

Abstract: Methods and systems for determining dance steps based on music and/or other dancers. A wearable computing system may include a head mounted display (HMD). The wearable computing system may receive a media sample including an audio sample associated with a song and/or a video sample associated with one or more dancers performing a dance. The wearable computing system may communicate the media sample to a content analysis server that may include a content identification module. The content identification module may provide information associated with a content of the media sample, such as identification of the song and the dance, to the wearable computing system. The wearable computing system may determine dance steps corresponding to the content of the media sample and may generate a display of the dance steps on the HMD.

Abstract: A system and method for presenting a group conversation on an electronic device of a user, via displaying, on a graphical user interface of the device, a group of contacts with which the user can communicate, the group of contacts comprising one or more individual contacts and one or more social circles which define a preset collection of contacts associated with one another. User input is received via the graphical user interface, the user input specifying a selection of participants from the group of contacts for a group conversation. The group conversation provides for sharing communication messages among the participants. A conversation window is presented on the graphical user interface. The conversation window displays a collection of contact icons with each contact icon respectively corresponding to one of the selected participants of the group conversation, and a conversation thread with the shared communication messages.

Abstract: A region classification server classifies a region based on region distribution information. The region classification server may include several databases to facilitate the classification of the region, including a classification type database, a classification evaluation database, and a region classification database. The region classification server may also include one or more interfaces for receiving region distribution information, such as an automated business listing interface and a user-input classification interface. The region classification server may also classify a region by modifying a classification evaluation stored in the classification evaluation database, where the modification is based on received user information. Moreover, the region classification server may provide the region classifications to other systems in communication with the region classification server, such as search engine providers, augmented reality developers, or other third-party entities.

Abstract: Various operations are disclosed for improving the operational efficiency of a virtual translation look-aside buffer (TLB) in a virtual machine environment. For example, operations are disclosed that allow for determination of whether present entries in shadow page tables (SPTs) are stale by comparing shadowed guest page table (GPT) entries against snapshots taken when the entries were cached. Other operations are disclosed that allow a virtual machine monitor (VMM) to access shadow page table trees (SPTTs) by walking trees in software or in hardware. Still other operations are disclosed allowing the VMM to use a hash table to relate GVA ranges to SPTs that map them, thus significantly reducing the cost of having to walk each SPTT in order to invalidate desired GVA(s). And, finally, operations are disclosed allowing the VMM to determine global GVA ranges by checking a bitmap, when invalidating global GVAs.

Abstract: A mobile device is operative to change from a first operational mode to a second or third operational mode based on a user's natural motion gesture. The first operational mode may include a voice input mode in which a user provides a voice input to the mobile device. After providing the voice input to the mobile device, the user then makes a natural motion gesture and a determination is made as to whether the natural motion gesture places the mobile device in the second or third operational mode. The second operational mode includes an augmented reality display mode in which the mobile device displays images recorded from a camera overlaid with computer-generated images corresponding to results output in response to the voice input. The third operational mode includes a reading display mode in which the mobile device displays, without augmented reality, results output in response to the voice input.
