A map is associated with a calendar entry. The image data are input into a first correlator which uses an incremental position of a new image and an absolute position of a preceding image to generate an estimated position. The stay is generally U-shaped and is detachably coupled to the seatback. Also, each ILB consistently self-asserts a backup ILB owner for each one of the TCP connections so the designated back up ILB owner takes over the processing of an ILB owned TCP connection should the ILB owner become incapable of processing the delegated TCP connection.
