Abstract: A system and method are provided for managing reader and writer threads in a caching proxy server. In general, a caching proxy server operates as an intermediary between a web server and a number of client devices. The clients send requests for digital assets hosted by the web server to the caching proxy server. For each request, or more particularly for each group of concurrent requests, for a particular digital asset, the caching proxy server operates in either a decoupled writer mode of operation or a reader/writer mode operation. In addition, while serving the requests, the proxy server may switch between the decoupled writer and the reader/writer modes of operation depending on one or more criteria.

Abstract: Where a separate bearer channel is required to be set up in a mobile network to complete a hybrid VoIP call on the mobile network as specified in 3GPP ICS standard TR 23.892, an alerting process may be started after a provisionable delay rather than upon completion of the network call setup. This allows the mobile network user to start responding to the impending call before signaling of the call has been completed, so that the person can answer closer in time to completion of call signaling. Additionally, the person who placed the call may be provided with ringing feedback to make it sound like the call has been completed. The amount of delay between receipt of a SIP invite and the onset of an alerting process may be specified in the mobile handset or may be specified as a header in the SIP invite. The amount of delay may be fixed or adjusted based on feedback.

Abstract: A system and method for identifying transient friends for a social network of a user are provided. A transient friend processing function obtains locations of a number of users or locations otherwise associated with the number of users. In order to identify transient friends for a first user, the transient friend processing function identifies other users associated with locations within a proximate area of the first user. For each of the identified users, the transient friend processing function compares a user profile of the first user to a user profile of the identified user to determine whether to add the identified user as a transient friend of the first user. If the transient friend processing function determines that the identified friend is to be added as a transient friend of the first user, the identified friend is then added as a transient friend of the first user.

Abstract: A system and method for tracking crowds of users are provided. In one embodiment, a central system, which includes one or more servers, operates to obtain current locations for users of mobile devices. Based on the current locations of the users, the central system forms crowds of users. As a result of movement of the users and corresponding location updates, the crowds move and change over time. In order to track at least some of the crowds, crowd snapshots for those crowds are created over time and stored. The crowd snapshots preferably maintain anonymity of the users in the crowd at the time the crowd snapshots are created. Thereafter, the crowd snapshots may be used to generate crowd tracking data for select crowds.

Abstract: A method and apparatus for controlling bandwidth in a Virtual Private Network assigns and allocates transmission bandwidth to packet VPNs for either connectionless or connection-oriented communication. The method creates two views of transmission facilities: a user plane view and a control plane view. In the user plane view, the bandwidth of the transmission facility is split into quantified and identified partitions. In the control plane view, transmission facilities are represented as logical links forming a topology that can be used for the purpose of routing the VPN. The two views are tied together by assigning user plane partitions to VPN control plane links. As a result, the allocation of bandwidth to VPNs becomes a controllable and viewable entity, thereby facilitating management and QoS provisioning in a VPN network.

Abstract: Systems and methods for providing a thematic playback experience in a peer-to-peer media recommendation system are disclosed.

Abstract: The present invention provides enhanced services from a packet network in association with incoming or outgoing POTS calls. These enhanced services may be provided without requiring control over any portion of the PSTN, which supports the POTS line over which the incoming or outgoing POTS calls are provided. A terminal adaptor is used to effectively connect a POTS line, a POTS-based telephone terminal, and the packet network. The terminal adaptor is configured to intercept POTS signaling associated with the incoming or outgoing calls, and send any resultant POTS signaling information to a service node or multimedia client associated with the telephone terminal to initiate the enhanced services via the packet network.

Abstract: The disclosure comprises a method for measuring the relative thickness of the lipid layer component of the precorneal tear film on the surface of an eye after distribution of the lipid layer subsequent to blinking. Light is directed to the lipid layer of a patient's eye with an illuminator. The illuminator is a broad spectrum light source covering the visible region and is a lambertion light emitter such that the light source is specularly reflected from the lipid layer and undergoes constructive and destructive interference in the lipid layer. The specularly reflected light is collected and focused using a collector such that the interference patterns on the tear film lipid layer are observable. The collector also produces an output signal representative of the specularly reflected light suitable for further analysis, such as projection on to a high resolution video monitor or analysis by or storage in a computer.

Abstract: A method and apparatus for treating gland dysfunction caused by gland obstruction in order to restore the natural flow of secretion from the gland comprises the application of a combination of energy, suction, vibration, heat, aspiration, chemical agents and pharmacological agents to loosen and thereafter remove the obstructive material.

Abstract: A method is provided that allows data access service provider subscribers to manage their telephone service through a data connection. The subscriber is enabled to obtain call data information and is provided real time control. During a data call, a visual incoming call indicator informs the subscriber, through a popup window, connected to the data access service provider that there is a call attempt. A visual message waiting indicator allows a subscriber, connected to the data access service provider to be notified of a pending message on the voice message system. A visual call disposition allows the subscriber, through the data connection, to dispose of calls. The call disposition options include forwarding a call to voice mail, playing an announcement to the calling party, forwarding the call to another line, sending a text message which could be converted to speech using text to speech technology, answering the call using voice over data call or terminating the data connection in order to accept the call.

Abstract: A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords ci, where i is a unique codeword index for each codeword ci. Each codeword defines weighting factors to apply to the MIMO signals, and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets Si for each codeword ci of the codebook C. Each codeword subset Si defines L codewords cj, which are selected from all the codewords ci in the codebook C. The codewords cj in a codeword subset Si are the L codewords in the entire codebook that best correlate with the corresponding codeword ci.

Abstract: Systems and methods measure a round trip delay of voice packets through a telephone system that includes a plurality of cabinets connected through a network. Each cabinet includes a link for communicating with other cabinets through the network by passing information such as voice packets. Each link includes a field programmable gate array (FPGA) that inserts and reads information in the voice packets to measure a time delay of the network. A first cabinet link sets a transmit bit in a voice packet directed to a second cabinet and starts a timer. The second cabinet monitors the transmit bit in received voice packets to determine if the bit is set. If so, the second cabinet sets a receive bit in the next outgoing voice packet directed to the first cabinet. The first cabinet monitors the receive bit in incoming voice packets and if set, stops the timer. The resulting value in the timer reflects the network delay.

Abstract: A system and method are provided for enabling a portable media player to obtain media content from secondary systems, such as other portable media players, via local wireless communication. In general, the portable media player stores proxy information identifying the media content of a number of media files in the user's media collection rather than the media files themselves. When a secondary system is within a local wireless coverage area of the portable media player, the proxy information for the media files, or a subset thereof, is provided to the secondary system. In response, the secondary system identifies media files stored by the secondary system having media content matching the media content identified by the proxy information. The secondary system then provides a notification of the identified media files to the portable media player, which may then obtain the identified media files from the secondary system.

Abstract: A ring control protocol is used to establish a separate control plane for a plurality of physically dual homed devices to enable collections of dual homed devices to be represented by a single pair of addresses into the attached routed Ethernet network. The gateway devices analyze the passing ring control packets to create direct mappings for data packets to the routed Ethernet network. Thus, although the dual homed devices are treated as a ring from a control perspective, the data path is implemented to be direct so that data packets continue to flow directly from the dual homed devices to each of the attached gateway devices. In one embodiment, each of the gateway devices implements a virtual switch and advertises the MAC address of the virtual switch into the routed Ethernet network rather than the MAC addresses of each of the attached Ethernet Switch Units.

Abstract: Alice generates a sequence of key bits forming an initial cryptographic key. Alice then uses the sequence of key bits and a sequence of cipher bits to control respective control parameters of a quantum encoding process applied to a sequence of quantum pulses, where the sequence of cipher bits used is known to Bob. Alice then releases the encoded pulses towards Bob over a quantum channel. Bob uses the previously agreed-upon sequence of cipher bits to control a control parameter, such as the quantum basis, of a quantum detection process applied to the pulses received from Alice, thus producing a detection outcome for each received pulse. Bob then derives a final cryptographic key from the detection outcomes. Because the cipher bits used to select the quantum bases used by both Alice and Bob are known by both parties, the method allows the final cryptographic key to be distributed with full basis alignment compared to 50% for BB84, thus allowing efficient quantum key distribution over multiple hops.
