Abstract: Augmented reality apparatus comprises stereoscopic display apparatus, a computer interface, and a rendering module. The stereoscopic display apparatus is arranged to provide to a user of the augmented reality apparatus a view of a real-world environment in which the user is located. The display apparatus is configured to generate a stereoscopic image that is visible to the user simultaneously with the real-world view. The computer interface is configured to receive from a network externally generated 3D model data of the real-world environment in which the user is located. The rendering module is configured to use the externally generated 3D model data to control the display apparatus to render a virtual element in a manner such that it is perceived by the user as a 3D element located at a desired location in the real-world environment.

Abstract: A user device has a display, a user interface and a network interface. The network interface receive a video data stream from another user interface. A user of the user device is able to pause the video stream. The paused image of the video stream and the video stream are both displayed on the display. The user is able to annotate the paused image.

Abstract: Techniques for visual configuration for communication session participants are described. According to various embodiments, a communication session is established that includes a video feed that is streamed between devices involved in the communication session. The video feed, for example, includes video images of participants in the communication session. A number of participants present at a particular device involved in the communication session is determined and used to generate instructions to other devices for visually representing video of the participants. According to various embodiments, user activity for participants in a communication session is detected and used to determine how the participants are visually represented for the communication session. For instance, users that are determined to be active in the communication session are presented visually more prominently than users that are less active.

Abstract: Techniques for presenting a message in a communication session are described. In at least some embodiments, a message is sent by a participant in a communication session. The message is presented in a graphical user interface (GUI) for the communication session and visually linked to a visual representation of the participant. According to one or more implementations, a number of messages that are presented in a GUI for a communication session is throttled.

Abstract: In at least some embodiments, when a participant in an online meeting begins to share a resource, such as their display screen, a new application window is automatically opened on a meeting room device and content associated with the participant's computing device is shared within the new application window. The participant can be a person in close proximity to the meeting room device. Alternately or additionally, the participant can be a remote participant.

Abstract: Meeting software on a meeting room device enables a meeting summary to be generated and sent to individuals associated with a meeting. The meeting summary may be triggered by a user, such as a meeting administrator. Alternately or additionally, the meeting summary may be automatically triggered and sent to the individuals associated with the meeting. The meeting summary can include a timeline of events that occurred throughout the meeting. In addition, the meeting summary can include content from the meeting and/or mechanisms to enable content from the meeting to be accessed by the recipients of the meeting summary.

Abstract: Meeting software on a meeting room device enables meeting room resources to be automatically shared. A meeting is initiated and, during the meeting, and associated meeting room device monitors for events pertaining to an interaction with one or more meeting resources. Responsive to detecting an event, the meeting room device automatically enables associated meeting room resources to be automatically shared among meeting participants.

Abstract: A user device has a display, a user interface and a network interface. The network interface receive a video data stream from another user interface. A user of the user device is able to pause the video stream. The paused image of the video stream and the video stream are both displayed on the display. The user is able to annotate the paused image.

Abstract: A method implemented during a communication event between a plurality of user devices over a communication network, the method comprising: identifying a first co-operating element in a first message transmitted from one of said user devices; identifying a second co-operating element in a second message transmitted from one of said user devices; querying a memory to identify an action associated with the combination of the first and at least the second co-operating element; and transmitting a message to each of the plurality of user devices to cause delivery of the action using output means at the plurality of user devices.

Abstract: The invention provides a method for treating hypoxia caused by high altitude by administering to a subject a compound that reduces the P50 of hemoglobin for oxygen.

Abstract: A microprocessor-controlled densitometer system for optically scanning a blood sample or the like and generating an electric analog signal which is a function of the optical density of the scanned sample. The electrical analog signal is processed and converted into digital data for storage in a memory as raw sample data to be retained until the next given sample is scanned. Under microprocessor control, a CRT device displays a re-constructed optical density analog waveform pattern representative of the generated electrical analog signal and may be normalized for full-scale readings.
