Abstract: A rowing machine to simulate the action of rowing a watercraft includes an energy damper, a handle, and a tensile member connecting the handle to the energy damper. The handle includes a grip member with a right hand grip and a left hand grip, and a connecting member connected to the tensile member. The connecting member is configured to transmit a force from the tensile member to the handle such that the force is substantially centered between the left hand grip and the right hand grip. The grip member is configured to rotate relative to the connecting member and provide at least one of a haptic indication and an audible indication when the grip member rotates relative to the connecting member from a first position to a second position that is substantially ninety degrees from the first position. The simulation may include actions to replicate feathering an oar.

Abstract: A teleconferencing system (1) comprises multiple teleconferencing bridges (5, 6, 7) each having an associated database (8, 9, 10). A server (20) hosts a local engine (22) associated with each bridge, and a multi-site engine (21). For a “global” conference utilising the resources of at least one other system (2), the multi-site engine (21) communicates over TCP/IP (36) with an equivalent multi-site engine of the other system to set up a link line via PSTN (31) between the bridges (5, 6, 7, 41). During the conference, the multi-site engine (21) automatically transmits event-driven updates to the remote system, and likewise receives such updates from the other system.
