| 20110048865 | SECURITY-BASED ELEVATOR CONTROL - An exemplary method of controlling a plurality of elevator cars includes determining that there is a security violation condition involving at least one of the elevator cars at a landing. That elevator car is prevented from moving from the landing until the condition is resolved. The other elevator cars are controlled such that they do not provide elevator service to or from the landing until the condition is resolved. | 03-03-2011 |
| 20110120813 | DYNAMIC ELEVATOR CAR DISPATCHING DURING AN ELEVATOR SYSTEM MODERNIZATION - An exemplary method is useful for handling passenger requests during an elevator system modernization that includes modernizing elevator cars over time. The modernized elevator cars are capable of servicing destination requests placed outside of an elevator car. Such destination requests include an indication of a desired destination. The exemplary method includes assigning an elevator car to respond to a new pending destination request according to a selected criterion for selecting between a modernized elevator car and an elevator car that has not yet been modernized. The method includes automatically updating the selected criterion responsive to a change in a number of modernized elevator cars. | 05-26-2011 |
| 20110147134 | METHOD OF HANDLING PASSENGER REQUESTS DURING ELEVATOR MODERNIZATION - An exemplary elevator system includes a first controller configured to recognize a hall call signal that indicates a passenger's desire to board an elevator car at a particular landing. The first controller is associated with at least one elevator car for assigning a hall call request to that elevator car. A second controller is configured to recognize a destination request that indicates a passenger's desire to be carried to a particular level. The destination request originates outside of an elevator car. The second controller is associated with at least one elevator car for assigning a destination request to that elevator car. The second controller is configured to determine whether a selected condition will be satisfied if a received destination request is serviced by an elevator car associated with the second controller. The second controller handles the received destination request in that manner if the condition will be satisfied. A cross dispatcher is configured to communicate with the second controller and to handle the destination request. If the condition will not be satisfied, the cross dispatcher provides an indication of a hall call signal corresponding to the received destination request to the first controller. | 06-23-2011 |
