Patent number: 7710951Abstract: The invention relates to a signaling method for a network system. In this solution, a common analog read signal is fed via a signaling channel to all nodal units under control of a control unit. The read signal is modified by modification means units at each nodal unit for identification of the nodal unit and data indicating the state of each nodal unit is added to the read signal. In the control unit, the state of each nodal unit is determined based on the modification made and the read signal.Type: GrantFiled: April 1, 2005Date of Patent: May 4, 2010Assignee: Kone CorporationInventor: Asko Juntunen

Patent number: 5886696Abstract: In a display (202) comprised in an elevator system, more than one floor symbol (205) but less than all the floor symbols corresponding to different floors in the elevator system are highlighted at a time. At least the floor symbol corresponding to the current position and that corresponding to the next floor in the travelling direction is highlighted. The display is preferably so controlled that it scrolls the floor symbols (205) with respect to the car symbol (203). When the elevator car is at a given floor, the floor symbol corresponding to such floor coincides with the car symbol, and when the elevator car moves away from the floor, the floor symbol ceases to coincide with that car symbol, and as the car comes to the next floor, the corresponding floor symbol coincides with that car symbol.Type: GrantFiled: September 8, 1997Date of Patent: March 23, 1999Assignee: Kone OyInventors: Markku Kakko, Juha Salminen, Asko Juntunen

Patent number: 5153808Abstract: The protected network consists of a signal bus provided with terminal impedances and connected via impedances to the supply voltage (+VIN) and signal ground (GND), and signal devices which are connected to the bus. To protect the network, the voltages on the bus are monitored, and the bus impedance is measured by means of a test pulse. If either the measured voltages, impedance, or both are outside an allowed range, at least the supply voltage (+VIN) of the signal devices is disconnected.Type: GrantFiled: May 2, 1990Date of Patent: October 6, 1992Assignee: Kone Elevator GmbHInventors: Asko Juntunen, Heikki Leppanen, Kimmo Selin
