Abstract: Described embodiments generally relate to a method of determining power delivered by a cable, the method comprising receiving data related to a residual magnetic field produced by the cable; determining a proportionality factor relating the received data to the power delivered by comparing the residual magnetic field data to independently measured reference data related to the power delivered by the cable; and based on the proportionality factor, determining the power delivered by the cable.

Abstract: Systems and methods for providing structured query language (SQL) access to non-relational data stores are described. SQL access can be provided to a non-relational data store in one embodiment by mapping storage attributes of the data store to one or more virtual relational tables. The virtual tables can include a schema representation of data stored in a non-relational data store without actually including the data in the virtual tables. In some embodiments, these systems and methods therefore advantageously merge certain benefits of relational database architectures with the scalability benefits of certain non-relational data store architectures. Certain features of the systems and methods described herein can also be used with existing relational databases. For example, the systems and methods described herein can perform join or similar operations between a relational table in one data store and a data object in another data store.

Abstract: A process for establishing a session between a first node and a second node of a communications network, the process including receiving a first request addressed from the first node and addressed to the second node; sending, in response to receipt of the first request, a response addressed to the first node to cause the first node to send a second request addressed to the second node, the response including first validation data; receiving the second request sent by the first node, the second request including second validation data; and determining, on the basis of the second validation data, whether to establish the session.
