Self-healing inter-carrier network switch
A vendor evaluator system enables real-time or near real-time efficiencies of an inter-carrier switch. At a nominal periodic rate (e.g., every fifteen minutes or less), the vendor evaluator system updates a performance map of vendor exchanges to which calls may be routed from the switch. Specifically, in real-time or in near real-time, an updated performance score is generated for each vendor exchange and/or for each NPA-NXX code that is connected to the switch based on a weighted average of post dial delay, average call hold time, and attempt-seizure ratio. The score is compared against performance thresholds to determine whether or not the respective exchange and/or code should be included in a pool of acceptably-performing, candidate vendor exchanges from which a particular exchange is selected to service a call. Such techniques prevent poorly performing vendors from servicing calls routed by the inter-carrier network switch in real time or near real-time. |

Address management in a connectivity platform
Disclosed are an approach form managing and assigning addresses in a connectivity platform that allows for proprietary connectivity modules (Providers) to plug into the operating system. In this disclosure, when a user/application/computing device, connects to another user on another computing device an address is generated for that user.

The invention relates to a method for acoustically emitting audio broadcasting signals in a vehicle, wherein audio broadcasting signals can be transmitted into the vehicle and received there over a first and at least a second reception path, wherein the first reception path is evaluated by means of at least one criterion parameter on the basis of an audio broadcasting signal that can be received over the first reception path, and the second reception path is likewise evaluated by means of a criterion parameter on the basis of the audio broadcasting signal that can be received over the second reception path.

In the preparation phase, the criterion parameter of the current reception path is compared to a second threshold value (S2) that is lower than the first threshold value (S1), and an examination of the switchover to the other reception path is performed if the criterion parameter of the current reception value is below the second threshold value (S2). |

Unguarded schottky barrier diodes
One embodiment of the disclosure relates to an unguarded Schottky barrier diode. The diode includes a cathode that has a recessed region and a dielectric interface surface that laterally extends around a perimeter of the recessed region. The diode further includes an anode that conforms to the recessed region. A dielectric layer extends over the dielectric interface surface of the cathode and further extends over a portion of the anode near the perimeter. Other devices and methods are also disclosed. |

Semiconductor device
An object of the present invention is to provide a semiconductor device combining transistors integrating on a same substrate transistors including an oxide semiconductor in their channel formation region and transistors including non-oxide semiconductor in their channel formation region. An application of the present invention is to realize substantially non-volatile semiconductor memories which do not require specific erasing operation and do not suffer from damages due to repeated writing operation. Furthermore, the semiconductor device is well adapted to store multivalued data. Manufacturing methods, application circuits and driving/reading methods are explained in details in the description. |
