Some skyscraper buildings and other types of installation feature a destination operating panel where a passenger registers their floor calls before entering the car. The system lets them know which car to wait for, instead of everyone boarding the next car. In this way, travel time is reduced as the elevator makes fewer stops for individual passengers, and the computer distributes adjacent stops to different cars in the bank. Although travel time is reduced, passenger waiting times may be longer as they will not necessarily be allocated the next car to depart. During the down peak period the benefit of destination control will be limited as passengers have a common destination.
What function does a "destination operating panel" feature?
a passenger registers their floor calls before entering the car

In late 1203, John attempted to relieve Chateau Gaillard, which although besieged by Philip was guarding the eastern flank of Normandy. John attempted a synchronised operation involving land-based and water-borne forces, considered by most historians today to have been imaginative in conception, but overly complex for forces of the period to have carried out successfully. John's relief operation was blocked by Philip's forces, and John turned back to Brittany in an attempt to draw Philip away from eastern Normandy. John successfully devastated much of Brittany, but did not deflect Philip's main thrust into the east of Normandy. Opinions vary amongst historians as to the military skill shown by John during this campaign, with most recent historians arguing that his performance was passable, although not impressive.[nb 8] John's situation began to deteriorate rapidly. The eastern border region of Normandy had been extensively cultivated by Philip and his predecessors for several years, whilst Angevin authority in the south had been undermined by Richard's giving away of various key castles some years before. His use of routier mercenaries in the central regions had rapidly eaten away his remaining support in this area too, which set the stage for a sudden collapse of Angevin power.[nb 9] John retreated back across the Channel in December, sending orders for the establishment of a fresh defensive line to the west of Chateau Gaillard. In March 1204, Gaillard fell. John's mother Eleanor died the following month. This was not just a personal blow for John, but threatened to unravel the widespread Angevin alliances across the far south of France. Philip moved south around the new defensive line and struck upwards at the heart of the Duchy, now facing little resistance. By August, Philip had taken Normandy and advanced south to occupy Anjou and Poitou as well. John's only remaining possession on the Continent was now the Duchy of Aquitaine.
What was John's only remaining possession on the Continent?
Duchy of Aquitaine
