Managed degradation of a video stream
A system and a method for simultaneous transmission of multiple media streams in a fixed bandwidth network are disclosed herein. The system is comprised of a central gateway media server and a plurality of client receiver units. The input media streams arrive from an external source and are then transmitted to the client receiver units in a compressed format. A state machine on the gateway media server detects if the network bandwidth is close to saturation. In one embodiment, the potential bandwidth saturation is measured by matching the time when the start of unit of media for each stream against the estimated transmission time for that unit. When any one actual transmission time exceeds its estimated transmission time by a predetermined threshold value, the network is deemed to be close to saturation, or already saturated, and the state machine executes a process of selecting at least one stream as a target for lowering total bandwidth usage. Once the target stream associated with a client receiver unit is chosen, the amount of data transmitted by the target stream is reduced, which could result in a lower data transmission rate. In one embodiment, the amount of data is reduced by a gradual degradation of the precision of the data, resulting in a greater potential for data compression, and/or by gradually reducing the resolution of the data of the target stream. |

Actively federated mobile authentication
To make a trusted web service call, a client application sends a series of messages to obtain tokens that allow service requests to pass through a service relay. The user obtains a first security token by providing the user's credentials. A second token is obtained from a trust broker that validates the first token. Both tokens are then sent with a service request to a service relay. The service relay validates the second token and then passes the first token and the service request to a connector service. The connector service validates the first token and passes the service request to a target back end service. The connector service acts as the user when communicating with the back end service. Service responses are routed back to the user through the connector service and the service relay. |

Reduced dimension time domain channel estimation in a wireless communication network
Methods and systems for obtaining improved joint channel estimates for a multi-user, frequency-multiplexed data transmission such as SC-FDMA or OFDM begins by estimating separate contributions of users (and/or other signal sources) to the received signal based on joint frequency domain channel estimates. A reduced data set is obtained by subtracting contributions of one or more users from the received data, leaving only the estimated contributions of the remaining users, with noise and residual estimation error signal. Time domain joint channel estimation is then performed on the reduced data set, which is feasible because the number of users has been reduced. In exemplary embodiments, the reduced data set includes only one estimated user contribution. This process is repeated to obtain time domain estimates for all of the users. The method can be repeated by using the TD channel estimates to re-estimate the user contributions and calculate revised TD channel estimates. |

A method for manufacturing an electronic component package. The method includes (i) providing a package precursor in which an electronic component is embedded such that an electrode of the electronic component is exposed at a surface of a sealing resin layer; (ii) forming a first metal plating layer such that the first metal plating layer is in contact with the exposed surface of the electrode of the electronic component; (iii) disposing a metal foil in face-to-face spaced relationship with respect to the first metal plating layer; and (iv) forming a second metal plating layer. In step (iv), the second metal plating layer is formed so as to fill a clearance between the first metal plating layer and the metal foil, thereby integrating the metal foil, the first metal plating layer and the second metal plating layer with each other. |
