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 |
20120241259 | ELEVATOR SECURITY SYSTEM - The present invention relates to a method of controlling access to floor within a building via elevator. The method includes receiving a passenger input indicating a desired destination floor a passenger seeks to travel to in an elevator, accessing a stored database containing data about which floors passengers are allowed to access via elevator when coming from the floor of the passenger input, determining if access is allowed based upon the desired destination floor and the data, and controlling operation of the elevator to deliver the passenger to the desired destination floor if access is allowed. | 09-27-2012 |
20140231177 | ELEVATOR SYSTEM WITH DYNAMIC TRAFFIC PROFILE SOLUTIONS - An exemplary method of controlling an elevator system includes determining that a temporary heavy traffic condition exists that includes a plurality of passengers requiring elevator service from an originating floor in the building that is distinct from a lobby floor. At least one elevator car out of a plurality of elevator cars within the building is temporarily dedicated to carry the passengers from the originating floor. A peak travel scheduling strategy is temporarily used for controlling the dedicated elevator car or cars for a selected period of time. | 08-21-2014 |
20140299421 | ELEVATOR PASSENGER INTERFACE INCLUDING SPECIAL ASSISTANCE FEATURES - An exemplary elevator passenger interface device includes a touch screen configured to allow a passenger to indicate a request for elevator service by touching the screen. An assistance button is positioned near the touch screen. A controller is configured to determine a destination requested by a passenger touching the screen. The controller is also configured to determine whether the assistance button has been manipulated and then to determine a destination requested by a passenger from a subsequent manipulation of the assistance button. | 10-09-2014 |
20150068848 | ELEVATOR PASSENGER INTERFACE INCLUDING IMAGES FOR REQUESTING ADDITIONAL SPACE ALLOCATION - An exemplary elevator destination entry system includes a passenger interface device that presents a visual representation of at least one item that will accompany a passenger on an elevator car. The passenger interface allows the passenger to select the visual representation. A controller is configured to receive indications of passenger requests for elevator service and an indication from the passenger interface device regarding a selected visual representation. The controller determines an amount of space within an elevator car required to accommodate the item based on predetermined space information corresponding to the selected visual representation. The controller assigns a car to a passenger request based on a determination that the assigned car will have adequate space to accommodate the passenger and the item. | 03-12-2015 |
