Abstract: The present invention provides a method for distributing information over parallel network interfaces. The method includes establishing a plurality of concurrent network connections using a plurality of network interfaces and determining a plurality of portions of information to be transmitted based on a plurality of data transfer rates associated with the plurality of concurrent network connections.

Abstract: A friction joint assembly 20 comprising a first arm 21 and a second arm 22 pivotally connected about pivot means, the pivot means including mechanical adjustment means comprising opposed frictional components adapted to be urged, one against the other, axially from a central axis region 23 about which the opposed frictional components are generally radially disposed.In a particular form, the opposed frictional components comprise a tubular member 24 on the one hand and opposed half members 26a, 26b located within the tubular member 24 on the other hand having a common frictional surface defined between them.The friction joint assembly 20 forms part of a vacuum arm assembly including at least one bendable joint supported by the friction joint assembly 20.
