Abstract: In a multi-user, collaborative environment, an operating system state change can occur by passing a stylus pen from one user to another. Upon detecting a change of the active user, a state machine transition can result in a change in a user experience. In one example, a change in the user experience includes a change in user interface (UI) functionality. Some examples include changing color of the digital ink being displayed, changing a handwriting pattern, and automatically switching a view displayed on the user interface. The switched view can be switching from a single-user model to a multi-user model. In another example, a state machine transition can result in establishing connections between devices (e.g., phones or laptops) associated with the users that used the pen.

Abstract: A technique is described herein for decoupling the playback of media content streams that compose a media item. In one implementation, the technique involves: in a synchronized state, presenting a stream of first media content (such as audio content) in synchronization with a stream of second media content (such as video content); detecting a desynchronization event; in response to the desynchronization event, transitioning from the synchronized state to a desynchronized state by changing (e.g., slowing) a rate at which the stream of second media content is presented, relative to the stream of first media content; detecting a resynchronization-initiation event; and, in response to the resynchronization-initiation event, returning to the synchronized state by providing a compressed presentation of the stream of second media content. The technique further involves presenting the stream of first media content at a given non-zero rate while in the desynchronized state.

Abstract: An optical connector arrangement for use on the bottom of a metallic box, the connector providing optical connection between a printed circuit card inserted into the metallic box and an optical cable. A sleeve assembly couples the connector to the box so as to provide lateral mobility of the connector with respect to the box. This lateral mobility facilitates alignment between an optical terminal protruding from the printed circuit card and an optical terminal of the cable. The connector further includes means for maintaining a pressure between the two terminals.

Abstract: The invention relates to optical communications by bundles of optical fibres. More particularly, the invention relates to a branching fiber optic connector device for optically and mechanically connecting two bundles of optical fibres with a single optical fibre and for supplying an electrical signal characteristic of the incident optical energy obtained by extracting part of the radiation in said fibre by means of a photodiode sealed to said fibre after removal of the cladding over a surface corresponding to the detecting surface of the photodiode, the refractive index of the sealing material being higher than the refractive index of the cladding.
