Patent CA-2336973-A1 (CA)
Inventor: JURMU RISTO
IPC: B62D7/02
Filed: 1999-06-28
Abstract: The invention relates to a bogie construction which comprises at least two stiff axles (1a-1c) which are interconnected by a rocking lever (10a, 10b). The rocking lever is pivoted in its middle so that it can move in its longitudinal direction as a result of steering movements.  The rocking lever is preferably connected to the bogie axle that turns least by means of a joint of an ear (13), and thus this axle determines the longitudinal displacement of the rocking lever. The rocking lever is connected to the other axles which turn more by means of suspension rods (8a, 8b). According to a preferred embodiment of the invention, a suspension rod pivoted below the axle is used, and thus the suspension rod can be made as long as possible. Consequently, the suspension rod tilts less as a result of the longitudinal movement of the rocking lever.

Title: Method and system for improved traffic management in wireless telecommunication systems
Inventor: CORBETT EDDIE
IPC: H04W16/06
Filed: 1999-09-24
Abstract: A technique is disclosed for traffic management in spread spectrum wireless telecommunication systems using different admission control levels on different frequency layers. In an embodiment of the invention, the capacity on a first frequency, having a specific admission control level, is permitted to increase to the point where the development of coverage holes occurs due to the effects of cell breathing.   This is compensated for by maintaining a designated frequency that is free from coverage problems by applying a stricter admission control relative to the first frequency. Thus calls or new access attempts affected by coverage problems on the first frequency are diverted to the designated frequency. The method improves overall network capacity and call quality in the network by more efficiently utilizing spectral resources.
