The connector fitting includes a chuck, which penetrates the opening and includes slits that extend in an axial direction. The chuck is radially outwardly expandable, in an insertion direction behind the opening into a clamping region containing the slits, and can be tightened on an outer side or in front of the opening of the housing by the thread and a matching tensioning nut, such that the clamping region can be withdrawn into the opening and thus braced against the longitudinal body. The tensioning nut includes an abutment acting in the axial direction and the chuck comprises a counter-abutment adjacent to its thread section, and the counter-abutment exerts pressure on the abutment in a released position of the chuck.

The digital cross-talk compensation module receives the digital real and imaginary signal components, estimates the cross-talk interference caused by each of the signal components, and outputs digital real and imaginary cross-talk compensated signal components.

Abstract: A gate having a latching mechanism which requires two distinctly different unlatching movements which occur in distinctly different directions, but where both of these unlatching movements can be performed with the use of only one hand. In addition, timer/alarm capabilities are provided to emit an alert signal in situations where the gate has been opened and has not been reclosed within a given time interval after the gate was opened. The gate has a self-closing spring assembly arranged within a pivot assembly. All of the above capabilities are obtained through a greatly simplified design which is extremely rugged and provides highly reliable service.

Abstract: A simulation is used to determine the effect of additional users on a communications system, such as a slotted wireless communications system. Users are sequentially added and determinations are made as to whether criteria for the additional user fall within predetermined limits. If the criteria are met, the user is accepted by the simulation and a power balancing is performed for all users. The simulation is repeated for each additional user. If the parameters are not within predetermined limits, the user is dropped. The simulation presents the system in a series of “snapshots” of communications activity.
