Access change for re-routing a connection
There is proposed a method and corresponding apparatuses allowing a change from a packet switched communication domain to a circuit switched communication domain.

In the application server, it is checked whether several conditions are met in order to determine whether the communication connection comprising the media flow is allowed to be changed to the circuit switched domain. If yes, the communication connection is changed from the packet switched communication domain to the circuit switched communication domain. |

Network infrastructure obfuscation
A shadow network, which can be a virtual reproduction of a real, physical, base computer network, is described. Shadow networks duplicate the topology, services, host, and network traffic of the base network using shadow hosts, which are low interaction, minimal-resource-using host emulators.

Systems, methods and devices for adaptable battery charging
Because a rechargeable battery has an increased number of uses (e.g., cycles), the battery's internal impedance can increase and the efficiency of the battery can become degraded. This internal resistance can cause cutoff voltage thresholds and cutoff current thresholds to prematurely stop a phase of battery charging, as these cutoff values can be based on low-cycle count batteries. New cutoff values can, instead, be based on battery impedance. Use of an adjusted cutoff current threshold during a constant voltage cycle can increase the capacity of high-cycle count batteries. Use of an adjusted cutoff voltage threshold in step charging can increase the charging speed of high-cycle count batteries. These increases in efficiency by using adjusted cutoff values can increase as the battery is further high-cycle count, in comparison with low-cycle count cutoff values used with high-cycle count batteries. |
