Patent number: 11597633Abstract: An elevator safety brake unit, an elevator including at least two of the safety brake units, and a method for testing the safety brake units are disclosed. Each safety brake unit includes a frame part, a movable composition movably supported on the frame part, a compression spring assembly associated with the movable composition, and adapted to activate a braking by pushing the movable composition forward, and a coil assembly of an electromagnet disposed in the frame part and adapted to deactivate the braking by pulling the movable composition backwards. Each movable composition includes at least two movable elements, one compression spring for each movable element, and at least one coil assembly adapted to deactivate the braking by pulling the at least two movable elements backwards.Type: GrantFiled: August 21, 2019Date of Patent: March 7, 2023Assignee: KONE CORPORATIONInventors: Joni Lappalainen, Henri Wenlin, Antti Saarelainen, Petri Alkula, Lasse Hurri, Andrej Burakov, Leena Ranta

Patent number: 7317924Abstract: A method allows a user of a mobile terminal to switch from a communication service currently active between that mobile terminal and another mobile terminal to a different communication service in such a manner that the end to end connection between terminals appears unbroken to the user. The user initiates the switch by inputting an appropriate command at the mobile terminal. The mobile terminal then transfers a request to the other mobile terminal. The request invokes a user interface on the other mobile terminal and prompts the user of the other mobile terminal to indicate whether or not they agree to switch from the currently active communication service to the other communication service. After receiving the user's response to the prompt, the other mobile terminal sends back a reply indicating the user's response. Signaling to perform the switch is initiated in response to the reply.Type: GrantFiled: February 22, 2005Date of Patent: January 8, 2008Assignee: Nokia CorporationInventors: Keijo Virtanen, Tarja-Leena Ranta

Patent number: 7162225Abstract: The invention relates to tracing of a malicious call to be implemented in a telecommunications network, especially in a mobile communication network. The inventive idea is that the called subscriber activates the tracing service in real time on finding the call to be malicious. One way of activating the tracing service is a service code sent from the called subscriber's terminal equipment and defined by the operator. The means required for implementing the service may be located according to the operator's wishes either in a mobile services switching center or in an intelligent network.Type: GrantFiled: February 22, 2001Date of Patent: January 9, 2007Assignee: Nokia CorporationInventor: Tarja-Leena Ranta

Patent number: 6337977Abstract: In a telephone system providing a voice mail service, a subscriber's voice mail follows the subscriber as he moves. In, for example, a satellite mobile telephone system, a subscriber may roam over wide areas. As he does so he registers sequentially with different satellite access nodes. These nodes may be on different continents. When the subscriber registers with a new satellite access node, the contents of his previous voice mailbox are transferred to a new voice mail box at the new satellite access node. The subscriber's home location register record and the visitor location register record, at the new node, are updated with the number of the new voice mailbox, so that new voice mail can be routed to the correct mailbox.Type: GrantFiled: February 6, 1998Date of Patent: January 8, 2002Assignee: Ico Services LimitedInventor: Tarja-Leena Ranta
