Abstract: An interactive display system including a wireless pointing device, and positioning circuitry capable of determining absolute and relative positions of the display at which the pointing device is aimed. The pointing device captures images displayed by the computer, using a rolling shutter, the images including one or more human-imperceptible positioning targets. The positioning targets are presented as patterned modulation of the intensity (e.g., variation in pixel intensity) in a display frame of the visual payload, followed by the opposite modulation in a successive frame. At least two captured image frames are subtracted from one another to recover the positioning target in the captured visual data and to remove the displayed image payload. The capturing of images at the pointing device is synchronized with the release of image data to the display, to avoid errors in the positioning operation.

Abstract: In one embodiment, an apparatus accesses a memory to obtain information regarding sharing history (as pertains, for example, to a particular user and/or device) and uses that sharing history to display at least one recommended sharing action (from amongst a plurality of available candidate sharing actions) as regards to a particular content item (such as, for example, a particular digital photograph, a video, a presentation, and so forth). This sharing history can comprise previously-selected sharing actions as correlated to content item types including shared-content recipients, corresponding temporal data, shared-content size, corresponding location data, and so forth. By one approach the apparatus itself serves to automatically track user-based content-sharing selections over time, which information is stored as the aforementioned sharing history.

Abstract: A system and method are disclosed for enhancing a television viewing experience by a group of one or more users. The experience is enhanced by integrating services from a number of different sources. This integration of services aggregates cloud data, identifies content from the aggregated cloud data that is potentially of interest to the user, and distributes that content to a main display or one or more secondary computing devices associated with the one or more users in the group.

Abstract: Systems, methods, and software can be used to process a link on a device. In some aspects, a link is received on a device. The link can be a link to content stored external to the device. The link can be selected by a user and associated with a first perimeter on the device.

Abstract: A control circuit detects an opportunity to send a message notwithstanding that no recipient is yet identified and identifies, without user input, a specific recipient from amongst a plurality of possible recipients of the message based, for example, on metadata regarding at least some of the possible recipients using one or more predetermined selection criteria. The control circuit can also determine a domain context for a message as corresponds to such an opportunity and use that domain context along with information corresponding to the message to query an invocation framework that cannot itself natively intuit domain context from the information. Received possible recipients can then be presented via a display to facilitate a user-based selection of one of the recipients.

Abstract: In some implementations, a method for managing data in a user device includes pushing first metadata for a first resource in a first perimeter to a service external to the first perimeter. The first perimeter is configured to prevent external resources from accessing resources in the first perimeter. Second metadata for a second resource in a second perimeter is pushed to the external service. The external service is external to the second perimeter, the second perimeter being configured to prevent external resources from accessing resources in the second perimeter. Information is presented to the user based on a combination of the first metadata and the second metadata.

Abstract: Information is shared between processing entities that each have a corresponding private data area by placing data corresponding to information for a first one of the private data areas for a first one of the processing entities directly into a second one of the private data areas for a second one of the processing entities without placing the data in an intervening shared data area and without directly invoking a system administrator-like entity. In addition, these private data areas can be pre-populated with a plurality of directories that each have a one-to-one correspondence to a particular predetermined information recipient and then providing a link to a given one of the recipients as corresponds to a given one of the directories when information is placed in that directory to provide the corresponding predetermined information recipient with at least read access to the information.

Abstract: In some implementations, a method of managing access to resources in a single device including receiving, from a first resource assigned to a first perimeter, a request to access a second resource assigned to a second perimeter different from the first perimeter. The single device includes the first perimeter and the second perimeter. Whether access to the second resource is prohibited is determined based on a management policy for the first perimeter. The management policy defining one or more rules for accessing resources assigned to the second perimeter including the second resource.

Abstract: In Transport Layer Security (TLS) or other communication protocols, the load on the server may be lowered by reducing the number of expensive decryption operations that the server has to perform. When a client contacts a server, the client sends the server the client's public key. The server chooses a secret value, encrypts the value with the client's public key, and sends the encrypted value to the client. When the client decrypts the secret, the server and client share a secret value, which may be used to derive an encryption key for further messages. In many key agreement schemes, the client chooses and encrypts the secret value, and the server recovers the value with an expensive decryption operation. By instead having the server choose the value and send it to the client, an expensive decryption operation is redistributed from the server to the client, thereby freeing server resources.

Abstract: In an example, one or more cryptographic keys may be associated with a group. Any member of the group may use the key to encrypt and decrypt information, thereby allowing members of the group to share encrypted information. Domain controllers (DCs) maintain copies of the group's keys. The DCs may synchronize with each other, so that each DC may have a copy of the group's keys. Keys may have expiration dates, and any client connected to a DC may generate a new key when a key is nearing expiration. The various clients may create new keys at differing amounts of time before expiration on various DCs. DCs that store keys early thus may have time to propagate the newly-created keys through synchronization before other DCs are requested to store keys created by other clients. In this way, the creation of an excessive number of new keys may be avoided.

Abstract: The Modular Adjustable Handlebar Kit contains a center mounting segment and linking units of varying degrees of angles, curves and/or segments with differing shapes both radius and straight and/or compounded curves with straights. Each of the linking units have a male and female end and are attached to adjoining linking units and center mounting segment via means of a plurality of aligning openings spaced about the circumference of each end of the linking units and a securing mechanism. The openings on the male end of the linking units form inner and outer rows, in which the openings are offset from each other. The female ends of the linking units have front and rear openings which are generally parallel to each other. The securing mechanism may be a clamping device and may utilize a dowel which extends through the aligned openings on the adjoined linking units. The clamping device is then secured to prevent disengagement of the pin.
