Abstract: Disclosed is a system for configuring a communication session. The system comprises a plurality of operator devices associated with a plurality of sales operators. The system further comprises a server arrangement coupled via one or more communication networks to the plurality of operator devices. The server arrangement is operable to receive information pertaining to a web page that is accessed by a consumer device associated with a given consumer. The server arrangement is then operable to analyze the information to select an operator device from the plurality of operator devices. Moreover, the server arrangement is operable to start the communication session between the consumer device and the selected operator device.

Abstract: An arrangement for measuring the position of a feed beam (1) in a rock drilling apparatus relative to a cradle (4) therein, or measuring the position of a rock drill (3) relative to the feed beam (1). In the arrangement an inelastic, flexible cogged belt (6; 13) is fixed to the feed beam (1) to the surface thereof, the cogged belt (6; 13) being installed to turn about the gear (9; 15) of a resolver mounted in a cradle (4) or movably with the rock drill (3), so that when the feed beam (1) moves relative to the cradle or when the rock drill (3) moves relative to the feed beam (1), the cogged belt (6; 13) rotates the gear (9; 15) of the resolver, and the resolver measures the position of the feed beam (1) or the rock drill (3) respectively.
