Brokering state information and identity among user agents, origin servers, and proxies
Methods, signals, devices, and systems are provided for using proxy servers to transparently forward messages between clients and origin servers if, and only if doing so does not violate network policies. In some systems, a transparent proxy uses a combination of standard-format HTTP commands, embedding auxiliary information in URLs and other tools and techniques to redirect an initial client request to one or more policy modules, such as a login server or an identity broker or an access control server. The policy module authenticates the request, and uses HTTP redirection to have the client transmit authorization data to the proxy. The proxy extracts the authorization data, directs the client to use a corresponding cookie, and subsequently provides the implicitly requested proxy services to the client in response to the client's subsequently providing the authorization data in a cookie. This is accomplished without requiring installation of any invention-specific software or hardware on either the client or the origin server, and also works with proxy servers that are known to the client. Unless the client request violates network policy, a person using the client will generally perceive no reduction of services, and will instead benefit from the proxy's caching and/or other performance enhancements.

The proposal may specify a time by which the content item will be published if the proposal is not rejected. The person may explicitly accept or reject the proposal, or may passively allow the content to publish by not rejecting the proposal before the specified time. The content may be published so as to be receivable by a set of one or more entities that have been designated to receive shared content items.
Method and system for transitioning between synchronous and asynchronous communication modes
Many different users may access, revise and update the same shared object simultaneously through several different transports. Clients may communicate asynchronously by accessing the shared object through a physical server. Clients may also communicate synchronously by accessing the shared object through a peer-to-peer network. A manifest file associated with the shared object identifies the locations where other versions and instances of the shared object are stored. The shared object and the associated manifest file allow a client to transition seamlessly between local access, synchronous and asynchronous communication such that the user is not aware that the mode of communication has changed. A user may change location and any available data sharing transports are automatically identified. Thus, the user may access a shared object and collaborate with other authorized users through different mechanisms.
System and method for providing highly available processing of asynchronous requests using distributed request and response queues and a service processor
Highly-available processing of an asynchronous request can be accomplished in a single transaction. A distributed request queue receives a service request from a client application or application view client. A service processor is deployed on each node of a cluster containing the distributed request queue. A service processor pulls the service request from the request queue and invokes the service for the request, such as to an enterprise information system. If that service processor fails, another service processor in the cluster can service the request. The service processor receives a service response from the invoked service and forwards the service response to a distributed response queue. The distributed response queue holds the service response until the response is retrieved for the client application.

Methods and apparatus for cochlear implant signal processing
A cochlear implant processing strategy increases speech clarity and provides higher temporal performance. The strategy determines the power spectral component within each channel, and dynamically selects or de-selects the channels through which a stimulation pulse is provided as a function of whether the spectral power of the channel is high or low. “High” and “low” are estimated relative to a selected spectral power, for example. The selected spectral power can be estimated by signal average or mean, or by other criteria. Once a selection of the channels to stimulate has been made, the system can decide that only those channels are stimulated, and stimulation is removed from the other channels. The selected channels are the ones on which the spectral power is above the mean of all the available channels. Fewer channels are stimulated at any time and the contrast of the stimulation is enhanced. Also, the temporal resolution increases as the number of channels that must be stimulated on a given frame decreases. This way, the channels which are presented to the patient are fewer in number and contain more temporal information.

Mechanism to improve preemption behavior of resource reservations
A technique is provided for one or more network nodes to deterministically select data flows to preempt. In particular, each node employs a set of predefined rules which instructs the node as to which existing data flow should be preempted in order to admit a new high-priority data flow. The rules are precisely defined and are common to all nodes configured in accordance with the present invention. Illustratively, a network node not only selects a data flow to preempt, but additionally may identify other “fate sharing” data flows that may be preempted. As used herein, a group of data flows has a fate-sharing relationship if the application instance(s) containing the data flows functions adequately only when all the fate-shared flows are operational. In a first illustrative embodiment, after a data flow in a fate-sharing group is preempted, network nodes may safely tear down the group's remaining data flows. In a second illustrative embodiment, when a data flow is preempted, all its fate-shared data flows are marked as being “at risk.” Because the at-risk flows are not immediately torn down, it is less likely that resources allocated for the at-risk flows may be freed then subsequently used to establish relatively lower-priority data flows instead of relatively higher-priority data flows.
