In addition, the system allows the user to store selected media programming while the user is simultaneously watching or reviewing another program. The system also allows stored media assets to be accessed locally via a media device connected to the unit or remotely via the Internet.

A distributed processing system delegates the allocation and control of computing work units to agent applications running on computing resources including multi-processor and multi-core systems. The distributed processing system includes at least one agent associated with at least one computing resource. The distributed processing system creates work units corresponding with execution phases of applications. Work units can be associated with concurrency data that specifies how applications are executed on multiple processors and/or processor cores. The agent collects information about its associated computing resources and requests work units from the server using this information and the concurrency data. An agent can monitor the performance of executing work units to better select subsequent work units. The distributed processing system may also be implemented within a single computing resource to improve processor core utilization of applications. Additional computing resources can augment the single computing resource and execute pending work units at any time.

This function is provided via communications adapters connected to each node and to a switched network to which are also attached nodes possessing likewise configured communications adapters which are capable of responding to a wide variety of message packet transfer protocol and modalities, all of which effect a direct memory to memory transfer without the need to copy data into intermediate buffers.

Traffic between logic LSIs and memory is increasing year by year and there is demand for increase of capacity of communication between them and reduction of power consumption in the communication. Communication distances between LSIs can be reduced by stacking the LSIs. However, in a simple stack of logic LSIs and memory LSIs, it is difficult to ensure heat dissipation to cope with increasing heat densities and ensure transmission characteristics for fast communication with the outside of the stacked package. Also required is a connection topology that improves the performance of communication among the stacked LSIs while ensuring the versatility of the LSIs. An external-communication LSI, a memory LSI, and a logic LSI are stacked in this order in a semiconductor package and are interconnected by through silicon vias. Output terminals of multiple stacked LSIs are connected to an input terminal of a through silicon via of the stacked memory LSI and input terminals of multiple stacked LSIs are connected to an output terminal of a through silicon via of the stacked memory LSI, thereby directly connecting both of the external-communication LSI and the logic LSI to a wiring line of the memory LSI.

A method and system for transparently combining remote and local storage to provide an extended file system such as a virtual local drive for a computer system client/user, e.g., a user of a pocket sized personal computer or a cable set-top box. A client device may load file system object data, storing the directories and files remotely, and retrieving the files only when required. Via its local storage, the extended file system handles unreliable connections and delays. When a connection to an extended file system server is present, the extended file system provides automatic downloading of information that is not locally cached, and automatically uploading of information that has been modified on the client. Extended file system attributes are employed to determine the actual location of file system data, and a lightweight protocol is defined to download or upload remote data by low-level components that make the remote source transparent from the perspective of the application. The system scales to large networks as it employs the lightweight protocol and establishes a connection only to retrieve and submit data.

Apparatus, and associated method, forms a direct data connection between mobile stations of a packet radio communication system. An SMS message is sent by an initiating mobile station to another mobile station between which communications are to be effectuated. The SMS message includes the IP address of the initiating mobile station. Once the SMS message is delivered to the other mobile station, the other mobile station is caused to obtain an IP address, if necessary. And, a socket connection is formed when the other mobile station returns a response message to the initiating mobile station. The mobile stations are each provided with the IP address of the other mobile station, and other needed information by way of which to form a direct connection upon which the data is communicated directly between the mobile stations.

A wireless communication apparatus compensates for phase and amplitude imbalances existing among transmit and receive branches, while also preventing likelihood information and SNR estimation error produced by such imbalance compensation. In an apparatus having a plurality of transmit and receive antennas and respective branches for each antenna, a calibration processor multiplies receive signals in each receive branch by antenna calibration coefficients, in order to correct phase and amplitude imbalances existing among the receive branches. A transmit beamforming matrix estimator then estimates a transmit beamforming matrix by using the multiplied receive signals. An estimator then solves for estimated values such as the noise power, likelihood information, and channel waveform equalization values for each receive branch, and in addition, derives a final estimated value that takes the multiplication by correction coefficients into account when averaging the estimated values for each receive branch or when computing a weighted average according to likelihood.

Systems and methods for communicating notice to limit battery degradation within a battery pack are disclosed. In one example, a signal is generated and passed between modules of a battery pack to provide notice to limit battery pack degradation. The system and method may be particularly useful for a battery pack with distributed battery modules.

A remote sensing system and method for instrumenting the entries to manhole enclosures, in order to provide a platform and means for sensing environmental parameters within and around the enclosures and wirelessly transmitting those parameters to a distant site. The system comprises a housing with sensor for monitoring environmental parameter in the vicinity of the manhole. A microcontroller in the housing sends the parameters to a radio module, which transmits the parameters to a communication device for alerting a user that a manhole has been tampered with.

A wireless access point is equipped with both an omnidirectional antenna and a directable antenna that can be selectively directed to any of a plurality of directional spaces overlapping the network space served by the omnidirectional antenna. The directable antenna is directed to an optimal directional space for a client when the access point is communicating with the client at a high data rate. The access point can intermittently exchange information with other clients using the omnidirectional antenna. The omnidirectional antenna enables broadcast signals to be transmitted to any client in the entire network space, but at a lower data rate. A preferred data rate and an optimal client directional space are re-determined periodically or as necessary based on parameters such as the data rate, signal strength, and rate of success in communicating data.

A switch instruction is transmitted from a PC terminal (105) to a portable PC terminal (107) (S302); the portable PC terminal (107) transmits a switch connection request to a portable communication terminal (102) on the other end of communication (S306); the portable PC terminal (107), when it is waiting for a response to the switch connection request and receives a switch connection request from the other end of communication, detects that switching processes are being performed simultaneously (S312); upon detection of the simultaneous switching, a switching session related to either switch connection request is determined to be continued (S314 and S315); the portable PC terminal (107), which received the switch connection request to which the switching session determined to be continued was related, transmits a success response including information on the switching process of the portable PC terminal (107) side (S316 and S319); and the PC terminal 101, which received the switch connection request to which the one to be stopped was related, transmits a failure response (S317 and S318). This allows switching to be carried out with quick and not many procedures in both end communication terminals performing multimedia communication with each other.

An automatic transmission apparatus includes an RFID tag including a one-shot call command data signal, a one-shot SMS command data signal and/or a one-shot Internet access command data signal, and a mobile terminal that includes an RF antenna, a base band chip, and an NFC controller that performs NFC with the RFID tag, and transmits the command data signal received from the RFID tag to the base band chip. Once a mobile terminal is tagged on the RFID tag, the mobile terminal performs call connection by automatically linking to a telephone number stored in the RFID tag, automatically links an SMS stored in the RFID tag on the screen of the mobile terminal so that the SMS may be activated, and/or automatically links to a particular address by using the web browser of the mobile terminal according to an Internet address stored in the RFID tag.

Messaging applications are enhanced with drawn images or words that appear on a communication device screen alongside messages. Users can express themselves more creatively as well as visually reference previously sent or received messages, such as by drawing an arrow to them or circling them. Graphic inputs are also operable to alter a sent message so as to convey additional or corrective meaning. By extending the drawing field outside the individual messages, this combination of messages and graphic inputs creates a third communication functionality not present in either messaging or drawing alone.

A wireless communication system includes a base station device and a mobile station device that tries a random access to the base station device. The mobile station device determines an upper limit of a random backoff time representing an interval from when the random access fails to when another random access is retried based on a relationship between the mobile station device and the base station device.

A system and method for exchanging information between clients separated by firewalls is disclosed. A server may receive the information as posted through a browser client from beyond a first firewall and relay it to another client beyond a second firewall without lowering the security levels of the firewalls.

A communication network includes an SS7 Security Gatekeeper that authenticates and validates network control messages within, transiting, entering and leaving an overlying control fabric such as an SS7 network. The SS7 Security Gatekeeper incorporates several levels of checks to ensure that messages are properly authenticated, valid, and consistent with call progress and system status. In addition to message format, message content is checked to ensure that the originating node has the proper authority to send the message and to invoke the related functions. Predefined sets of templates may be used to check the messages, each set of templates being associated with respective originating point codes and/or calling party addresses. The templates may also be associated with various system states such that messages corresponding to a particular template cause a state transition along a particular edge to a next state node at which another set of templates are defined. Thus, system and call state is maintained. The monitor also includes signaling point authentication using digital signatures and timestamps. Timestamps are also used to initiate appropriate timeouts and so that old or improperly sequenced message may be ignored, corrected or otherwise processed appropriately. The SS7 Security Gatekeeper may be located at the edge of a network to be protected so that all messaging to and from the protected network most egress by way of the Gatekeeper. Alternatively, the SS7 Security Gatekeeper may be internal to the protected network and configured as a “pseudo switch” so that ISUP messaging is routed through the Gatekeeper while actual traffic is trunked directly between the associated SSPs, bypassing the Gatekeeper.

An apparatus and method for defining content distribution paths in a content distribution network integrate unicast and multicast connections. Content engines in the content distributed network are organized into channels with a master content engine maintaining specific content. The content distribution network is further organized into a distribution hierarchy based on network topology and channel definitions, first by establishing unicast paths through the content distributed network and then by integrating multicast paths into the unicast hierarchy. The further organization of the content distribution network establishes distribution trees from the channel masters to the network edges.

An automated parking system and method for controlling a parking garage employ a distributed control system to control the transport of a vehicle between an entry/exit station and a parking space.
