Abstract: A method of communicating presence information is provided. The method includes receiving (210) at a controller node a location identification indication from a mobile device. The location identification is based on a location identifier received at the mobile device from a broadcast node. A conference status of the mobile device is determined (220) at the controller node based on the location identification indication and a device identifier of the mobile device. The mobile device is instructed to update (230) a presence indication when the mobile device meets a conference status criteria.

Abstract: A method and apparatus for winding conditioned material onto a spool so as to maintain its desirable properties. In one embodiment, decorative ribbon is conditioned using a curling device and wound onto an elongated spool having a predetermined radius in an alternating, helical lay pattern so as to maintain the curl of the ribbon, and permit easy removal and storage thereof. In a second embodiment, two or more different types or colors of ribbon are wound either concentrically or in juxtaposed orientation onto the same spool. An apparatus for winding one or more of the aforementioned spools is also disclosed. A multi-spool dispenser for the curled ribbon is further described.
