Patent number: 10453280Abstract: A method for controlling access in an environment, including the use of an access control system to lock/unlock access devices in the environment, which control system is configured to communicate via a short range communication system with at least one first mobile phone of a first user wanting to get access to at least one access-restricted area of said environment, and which control system is configured to communicate with a second communication device of a second user located in said environment and holding access rights to said area. After the first user enters the environment, the control system initiates the first mobile phone via the short range communication system to send an access request to the second communication device, which access request includes a unique ID of the first mobile phone.Type: GrantFiled: January 11, 2018Date of Patent: October 22, 2019Assignee: KONE CORPORATIONInventor: Risto Kontturi

Publication number: 20150073748Abstract: The invention relates to a method for measuring the traffic flow in a building having a people mover system, in which method the following succession of steps is performed: at least two monitoring units with at least one sensor are temporarily installed in the vicinity of entrance- and/or exit area(s) of at least one people mover, each of the monitoring units is provided with a power supply for being operated as an independent unit, events caught by the sensor are associated with the current event time and with the location/position of the corresponding monitoring unit as correlated event/event time/event location data, which correlated event/event time/event location data is used to compute a traffic flow in the building. This data can be advantageously used in the call allocation of a new people mover system of said building.Type: ApplicationFiled: November 17, 2014Publication date: March 12, 2015Applicant: KONE CORPORATIONInventors: Veikko MATTSSON, Risto KONTTURI

Patent number: 7610995Abstract: A method and a system for responding to a service request sent to a transportation service, determining one or more alternatives as a transportation device for the user and selecting a personal transportation device. An automated transportation system according to the invention may contain a plurality of elevators in an elevator group, a passenger terminal device for reserving elevators for use by passengers, and an elevator group control system responsive to the passenger terminal device for controlling the elevators. The method of the invention involves entering a personal service request via the terminal device, determining on the basis of the service request at least one alternative as a transportation device for the user, and selecting via the terminal device one of the alternatives as the transportation device.Type: GrantFiled: August 9, 2007Date of Patent: November 3, 2009Assignee: Kone CorporationInventors: Jari Ylinen, Risto Kontturi

Patent number: 7581621Abstract: A method and an apparatus controls advance opening of doors in a double-deck elevator, in which elevator a car frame supporting the elevator cars is moved by means of a set of hoisting ropes by a hoisting machine provided with a traction sheave. When the elevator is approaching the target floor levels, the velocity of the elevator cars in the car frame in relation to the car frame is measured and, based on the measurement result, the velocity of the elevator cars relative to the floor levels is calculated.Type: GrantFiled: June 10, 2008Date of Patent: September 1, 2009Assignee: Kone CorporationInventor: Risto Kontturi

Publication number: 20080289907Abstract: The invention relates to a method and an apparatus for controlling advance opening of doors in a double-deck elevator, in which elevator a car frame (2) supporting the elevator cars (1a and 1b) is moved by means of a set of hoisting ropes (3) by a hoisting machine (46) provided with a traction sheave. When the elevator is approaching the target floor levels (51, 52), the velocity of the elevator cars (1a and 1b) in the car frame (2) in relation to the car frame (2) is measured and, based on the measurement result, the velocity of the elevator cars (1a and 1b) relative to the floor levels (51, 52) is calculated.Type: ApplicationFiled: June 10, 2008Publication date: November 27, 2008Applicant: KONE CORPORATIONInventor: Risto Kontturi

Patent number: 7347303Abstract: A method and a system for generating a request for elevator service in which the elevator user receives with his/her terminal a general transmission of information about the elevator system from base stations placed in the elevator lobby of the building. By way of the terminal, a service request is generated on the basis of the goal and the information provided by the general transmission. The service request is transmitted further to an elevator group controller via an edge server and a local server. The edge server checks the request for correctness, and the local server functions as a point of connection between the elevator group and the external world.Type: GrantFiled: November 22, 2006Date of Patent: March 25, 2008Assignee: Kone CorporationInventors: Risto Kontturi, Jari Ylinen

Patent number: 4870663Abstract: A method is disclosed for selecting different modes of operation of a means used for counting objects in a given area, such as persons waiting in an elevator lobby. In the method, the movements of the objects are monitored with at least one Doppler radar by observing the Doppler frequencies of the signals reflected by the objects. The method is characterized in that the operation of the means is switched between two modes of operation, so that the mode of operation primarily carrying out the counting of objects on the basis of their stopping and starting is used during a given time interval, and the mode of operation primarily observing merely the movements of the objects is used during another given time interval.Type: GrantFiled: February 17, 1988Date of Patent: September 26, 1989Assignee: Kone Elevator GmbHInventors: Hannu Kulju, Risto Kontturi
