Abstract: The present disclosure is directed to methods and apparatus that monitor pedestrian traffic and that adjust the behavior of traffic signals at intersections and “walk”-“do not walk” indicators associated with particular crosswalks. Methods and apparatus consistent with the present disclosure may receive image or sensor data, may monitor the status of different traffic flow, and may adjust the timing of signal lights or walking indications as conditions change at an intersection. In certain instances, a traffic controller at one intersection may receive information collected by other traffic controllers along a set of streets that lead to a particular intersection. Traffic controllers that receive images of an intersection may identify partition the intersection into a set of safe and unsafe zones as those traffic controllers identify when pedestrians can safely cross an intersection.

Abstract: A transport arrangement system operates to provide a service, which can receive a transport pool request from a rider. The transport pool request can specify a set of parameters, including a pickup location and a drop-off location. A candidate set of transport providers are identified that satisfy one or more criterion, including a criterion of proximity relative to the pickup location. One of the candidate set of drivers is selected to provide a transport pool for the rider. The selection can be based at least in part on determining which individual drivers of the candidate set satisfy one or more constraints, including a first constraint that relate to a predicted trip completion time for the rider.

Abstract: One embodiment of the present invention provides a system for communicating data using a socket interface with multiple transport layer implementations. During operation the system creates a socket which can be used with a set of transport layer implementations. Next, the system binds the socket to a local port without specifying a particular transport layer implementation. The system then receives a request to connect to a target port that is associated with a target address. Next, the system selects a protocol implementation from the set of transport layer implementations using the target port and the target address. The system then sends a connection request to the target port using the selected protocol implementation. Note that the present invention does not require changing a networking application because the transport layer implementation is selected automatically by the system, instead of requiring the application to possess the knowledge to select the appropriate transport layer implementation.

Abstract: A system, method and computer program product are provided for enhancing participation in an educational environment using networked devices. In one embodiment, feedback is received from a plurality of individual group members regarding material being presented by a group leader utilizing a plurality of networked devices operated by the individual group members. Subsequently, such feedback is processed. The processed feedback is then transmitted to the networked devices operated by the individual group members.

Abstract: Methods, systems, and computer program products for improving network operations by dynamically undeploying services (such as web services or other network-accessible services) in a computing network. A process is defined whereby conditions such as usage metrics for incoming client requests (or other network conditions such as load balancing considerations) are monitored, and used to trigger dynamic undeployment of web services from locations in the network. The undeployment may apply to distributed locations of a service, and may also apply to an origin server from which the service was originally deployed. Service requests are dynamically routed to the destination where the service resides, in a manner which is transparent to the client.

Abstract: A method for managing objects in a clustered network includes a file system containing at least one copy of a data object. The method can involve several clustered servers in communication with the file system. A distributed consensus algorithm is used to select a host server. The selected host server can contain a copy of the data object, such as in local cache, providing access to the local copy to any other server in the cluster. Any change made to an item hosted by the host server can also be updated in the file system. If the host server becomes unable to host the object, a new host can be chosen using the distributed consensus algorithm. The other servers are then notified of the new host by multicast messaging.
