A system and method provides dynamically selected media content to someone using an electronic device in a social network environment. Items of media content are selected for the user based on his or her relationships with one or more other users. The user's relationships with other users are reflected in the selected media content and its format. An order is assigned to the items of media content, for example, based on their anticipated importance to the user, and the items of media content are displayed to the user in the assigned order. The user may change the order of the items of media content. The user's interactions with media content available in the social network environment are monitored, and those interactions are used to select additional items of media content for the user.

A computer system may be configured to dynamically select a memory virtualization and corresponding virtual-to-physical address translation technique during execution of an application and to dynamically employ the selected technique in place of a current technique without re-initializing the application. The computer system may be configured to determine that a current address translation technique incurs a high overhead for the application's current workload and may be configured to select a different technique dependent on various performance criteria and / or a user policy. Dynamically employing the selected technique may include reorganizing a memory, reorganizing a translation table, allocating a different block of memory to the application, changing a page or segment size, or moving to or from a page-based, segment-based, or function-based address translation technique. A selected translation technique may be dynamically employed for the application independent of a translation technique employed for a different application.

A computer system for conserving operating power includes a number of computer hardware processor cores that differ amongst themselves in at least in their respective operating power requirements and processing capabilities. A monitor gathers performance metric information from each of the computer hardware processor cores that is specific to a particular run of application software then executing. A workload transfer mechanism transfers the executing application software to a second computer hardware processor core in a search for reduced operating power. A transfer delay mechanism is connected to delay a subsequent transfer of the executing application software if the system operating power may be conserved by such delay.

Systems and methods to select media content are provided. A method includes dynamically selecting content items for presentation via a media player based on user media selection settings. The user media selection settings specify a proportion of a first category of media content to be presented and a proportion of at least one second category of media content to be presented. The at least one second category includes a user defined category. First media content is associated with the first category based on an intrinsic property of the first media content and second media content is associated with the user defined category based on a property that is not intrinsic to the second media content. The method also includes generating an output stream presenting the dynamically selected content items.

Network configuration hierarchy information is maintained using flexible mechanisms and methods for establishing routes and transferring information between nodes in ad-hoc data communication networks using on-demand multicast and unicast techniques. Communication nodes use network topology information to build and maintain a dynamically mobile, wireless, ad-hoc network capable of efficiently routing both unicast and multicast traffic. Network nodes that facilitate the collection and distribution of network topology and routing data are dynamically selected, configured, and maintained. Network traffic overhead necessary for maintaining and distributing network routing table information is held to a minimum and efficiently distributed across the network, thereby reducing the potential for network traffic bottlenecks due to network overhead processes.

Autoband's distributed networking intelligence provides a novel architecture capable of dynamically reconfiguring communications pathways consisting of links whose transmission media are opportunistically and dynamically selectable. At least one constituent node in such automatically configurable transient pathways is mobile, for example, information (source) server, intervening router node(s), gateway server and / or client device. Additionally, Autoband's ad hoc communications pathways may seamlessly and dynamically integrate (i.e., “graft”) into standard fixed node networks such as terrestrial networks, other wireless networks or combinations thereof. These communications may consist of point-to-point or multicast links. An economic market-based approach further assures allocation of available network resources (i.e., bandwidth and processing) needed to achieve the most optimally resource efficient communications pathway configurations for the totality of communications. Consequently, optimal network resource allocation and efficiency at a system-wide level is continuously achieved.

An apparatus, system, and process are disclosed for dynamically determining a best network service for an electronic computing device. A network query module queries two or more active networks to determine the network characteristics, such as bandwidth, security level, and cost, of each network. A service level module determines a service level associated with each active network. The service level is determined based on an algorithm using the network characteristics of each network. A best network module determines the best network from the active networks based on the service levels of each network, and a network connection module dynamically connects the electronic computing device to the best network. The network selection apparatus may also maintain and use a profile module to store default, user-defined, application, and network profiles. A dynamic switching module may dynamically switch between active networks as the service levels of individual networks are re-evaluated and the network characteristics of each network change.

An improved system and method for presenting computerized interactive forms (such as survey questionnaires, employment applications, etc.) via the Internet to human respondents making use of client computers. The invention is a cross-platform web application written in Java and JavaScript. The presented questions / items are selected dynamically as a respondent fills in the information for each question / item. A code-length-reducing software architecture—wherein all objects are widgets—along with a design choice of inheritance makes for maximum code clarity, impressive code compactness, and swift parsing. More information and a higher quality of information are collected from a respondent, because waiting time is reduced and only relevant questions are presented. Implementation of parent-child containment in the widget set, coupled with a JavaScript skeleton design system, facilitates respondent-friendly display design by interface designers, and a rapid design process.

Methods, systems, and computer program products for improving installation of software suites by automatically and dynamically obtaining information pertaining to the heterogeneous run-time environment in which the suite will be installed, and using this information as input to a rules engine which evaluates rules to dynamically select a predetermined topology-specific configuration of the suite. The software installation process is thereby adapted and configured dynamically based on the unique topology of the environment in which the suite is being installed, yet the burden on the software installer to understand the intricacies of his run-time environment (and to reflect those details in the suite customization process) is greatly reduced. Software installation is therefore quicker, easier, and less error-prone than in prior art approaches.

An architecture and method for performing dynamic route discovery and time slot reservation provisioning within optical-switched networks. The method employs extensions to the RSVP-TE signaling protocol, which uses various messages to reserve resources. Under a peer routing embodiment, routing trees and resource availability data are maintained by the edge nodes. A lightpath route is dynamically selected based on selection criteria applied to the routing tree data and the availability of resources along the lightpath. Link state information, including resource reservation data, is broadcast by the switching nodes to update the edge nodes of their resource availability. A resource reservation message is passed between nodes defined by an explicit route contained in the message, and resource availability is confirmed for the entire lightpath prior to confirming the resource reservations.

Selectively obfuscating, or obscuring, a portion or portions of information in a multi-party transmission. A user participating in a multi-party exchange signals a communication device (or proxy) that he will provide private information that is to be perceptible only to a subset of the other participants. This user also identifies that subset, preferably by providing a group identifier for a group in which that subset of participants are members. The communication device transmits a member-specific descriptor comprising an encrypted version of a group key, and uses this group key to encrypt the private information that is to be perceptible only to the subset. Device-specific characteristics of participant devices are used, in addition to user-provided data (such as a user's log-on identifier and / or password), as input to create cryptographic key information. Only participants in the subset can decrypt the encrypted private information; other participants preferably receive a filler pattern of some type instead.

A content distribution system is provided to facilitate e-commerce transactions for products and services associated with distributed content. A content stream comprising content blocks, reference content blocks and floating reference content blocks uses metadata to identify products and services associated with content blocks. The metadata and floating reference content blocks are used to substitute dynamically selected content for content blocks based on profiles of user(s), the broadcast station, the advertisement spot defined in the stream and content available for substitution. A market server determines optimal matches to support content substitution, and performs brokerage and bidding functions among suppliers of products or services associated with content selected by users.

Methods, systems, and computer program products for automatically transforming data or business messages to enable communication between parties in a distributed computing environment (e.g. between business partners who exchange data over a public network, and who do not necessarily use the same data formats), where this data transformation preferably occurs at the edge of the computing network. A set of transformation services is described, and include template registration, transformation, forward, and receive services. Services from this set may optionally be combined to create composite transformation services. A template defines how to transform one data format into another. Selection criteria may be provided to enable dynamically selecting a template at run-time. Using these services, one business partner simply hands its data off into the network to a network-accessible transformation service, where the data is automatically transformed into a format usable by its business partner and forwarded to that business partner.

Autonomous selection between multiple virtualization techniques implemented in a virtualization layer of a virtualized computer system. The virtual machine monitor implements multiple virtualization support subsystems that each provide for the comprehensive handling of potential virtualization exceptions. A virtual machine monitor resident performance monitor computes relative virtualization overhead costs that are and would be incurred in using different virtualization support subsystems for virtualization exceptions that occur in executing a guest operating system within a defined interval. Dependent on the relative virtualization overhead costs determined, the virtual machine monitor resident virtualization selection control switches the virtual machine monitor to use the optimal virtualization support subsystem for handling virtualization exceptions that occur over a second defined interval.

A technique manages targets to which probe packets are sent from a source of a computer network. The novel target management technique dynamically selects an optimal set of valid targets for a particular (monitored) prefix of the computer network. Specifically, one or more targets are selected from a pool of possible learned and configured targets to be used as representatives of the monitored prefix. Probe packets are sent from the source to the selected targets for the duration of an evaluation period. Targets that do not respond to the probe packets during the evaluation period are invalid and deselected, and if available, an unused target is selected from the pool of possible targets to replace each non-responding target for a next evaluation period. Invalid learned targets are discarded, while invalid configured targets are returned to the pool of possible targets for potential re-selection in a later evaluation period.

In a GSM / EDGE Single Antenna Interference Cancellation (SAIC) operation environment, a mobile station is required to operate in a wide range of interference levels. An SAIC linear equalizer that takes advantage of the GMSK signal structure performs better than a conventional Maximum Likelihood Sequence Estimation (MLSE) equalizer in high interference levels, while it performs worse in low interference levels. A dynamic selection between the SAIC linear equalizer and the MLSE equalizer for each received burst is achieved to provide the optimal performance across the entire required operation environments. The dynamic selection is based on the estimated noise plus interference energy relative to the total received signal energy. The soft information calculated by the two categories of equalizers is properly scaled to generate soft information with balanced magnitude.

Dynamic frequency selection based on CR is provided. A CR BS detects an interference-free and unused frequency band. When sensing a new BS that has great signal strength and requires the frequency band during communications in the frequency band, the CR BS releases the frequency band and dynamically selects another frequency band to avoid interference.
