Abstract: A downhole stabilizer (5), such as a drill motor stabilizer, comprises at least one reaming means and/or reinforcing means (10). The present invention also relates to an assembly (30), such as a downhole drilling assembly (31), comprising at least one such stabilizer (5) and/or a drill bit (40,41) comprising a gauge bit (42) at or near a drilling end (45) thereof, and a connection means (46) for connecting the drill bit (40,41) to a drill motor assembly (60), wherein the drill bit gauge (42) comprises a substantially cylindrical portion having a length less than or equal to approximately 1.0 times the nominal bit diameter. The present invention also relates to a novel locking mechanism (80), such as a lock and key mechanism, to allow locking of a shaft (70?), e.g. a motor drive shaft (71?), through or together with a stabilizer (5?).

Abstract: An architecture for monitoring quality of service in a telecommunication network having a set of terminals provides for the terminals of the set of terminals to house measuring agents able to be configured to interlace with processes selected among processes for managing the application sessions of the network and processes for measuring the operating conditions of the network itself. Also provided is a management and configuration sub-system having a module for scheduling quality of service measurement campaigns capable of involving respective sub-sets of terminals according to a set of characteristics identifying the measurement campaign. The scheduling module is capable of configuring, for the purposes of the execution of the measurement campaigns, the measuring agents housed by the terminals included in the related subsets according to the set of identifying characteristics.

Abstract: Monitoring system includes a set of peripheral monitoring agents including processing functionalities housed in SIMS. Such processing functionalities, depending at least on operating conditions of each terminal and its respective SIMS, are able to adaptively establish a distribution of measuring functionalities included in the peripheral monitoring agents between the terminal itself (for example storing them in the related memory or multimedia card) and its respective SIM.
