Method and apparatus to generate a dynamic contact list of contact and presence information about contact events in a communication system when a calling entity unsuccessfully attempts to communicate with a called entity. When such a contact event occurs, a routing processor or call agent generates contact information about the contact event, including the calling party, called party, time of the contact event, and purpose of the contact event. A presence management processor also generates the presence information about the calling party's subsequent availability for return communication, including if a calling party is available for return communication, when the calling party is available for return communication, how long the calling party is available for return communication, and how the calling party is available for return communication. This contact and presence information is displayed to the called party in a dynamic contact list that includes contact and presence information for a plurality of contact events and calling parties, respectively. The called party is thereby able to determine what contact events occurred while the called party was unavailable for communication, and in what manner to return communicate with those calling parties that attempted to communicate with the called party while it was unavailable.

A final result of the directory search request is then produced by coalescing the first and second result sets. This final result includes both directory information and dynamically updated contact information for each person whose name was included in the final result.

A dynamic contact routing system includes establishing a plurality of service provider accounts. The service providers submit bids for a per-contact charge. A contact list is created wherein the service providers are ranked from the highest bidder to the lowest bidder. A contact received from a potential customer is routed to the highest ranked bidder service provider on the contact list. If the contact is not responded to or rejected, the contact is rerouted to the next highest ranked service provider on the contact list. The service provider's account who has received the contact is charged the pre-contact amount by that service provider.

A conveyor for orienting and registering articles in a preferred orientation and position for accurate downstream processing. The conveyor includes a conveyor belt running in a conveyance direction next to an orientation belt running parallel in an opposite direction or more slowly in the same direction. The orientation belt has upstanding structure, such as flights, or a high-friction surface. The conveyor belt includes article-supporting rollers on a top side. The rollers are arranged to rotate about axes oblique to the conveyance direction. The rollers also extend below the bottom side of the belt and are rotated by dynamic contact with bearing surfaces supporting the belt as it advances in the conveying direction. The rotating rollers direct conveyed articles toward a side rail. If a portion of a conveyed article extends past the side edge of the conveyor belt into the path of the orientation belt, the obstructions or high-friction surface of the slower- or oppositely-moving orientation belt strikes the conveyed articles and cause them to rotate clockwise toward an alignment of the article in the conveyance direction and into registration against the side rail at the downstream end of the conveyor. In other versions of the article-orienting conveyor, the orientation belt is replaced by a row of posts or a rotating paddle wheel that strikes conveyed articles extending past the side edge of the conveyor belt.
