Abstract: The present invention relates to a barrier laminate comprising: a first cellulose substrate comprising highly refined cellulose fibers; a tie layer comprising a hot melt adhesive and a second cellulose substrate wherein the peeling strength between the second substrate and the tie layer is between 3-5 N. The present invention also relates to a method for manufacturing said barrier laminate.

Abstract: The invention relates to a protective material (1) which can be used in the applications of public healthcare, rescue services, transportation of patients and nursing institutions. According to the invention, the protective material is an elongated plate-type material, the protective material being in the form of a layered structure including at least a body layer (2) with at least a core layer (3) formed from a network-reinforced polymeric material, and at least one absorbent fiber-based layer (4) which is provided to the upper surface of the body layer (2) and at least partially connected to the upper surface of the body layer, and edge reinforcements (9) provided to the longitudinal outer edges of the body layer in the protective material and connected to the upper surface of the body layer (2). In addition, the invention relates to the use of the protective material.

Abstract: A method for modernizing the control system of a bank of elevators, wherein in a first stage, the elevators are connected to work under elevator-specific computers controlled by a control system comprising a group controller and communicating by means of at least one serial communication bus. The connection is effected using passive adapters between the computers and the old elevator controller. For completing the modernization process of the individual elevators, the elevator-specific functions are modernized by replacing their old functions with functional modules and/or by adding functional modules performing new functions. The functional modules are connected to the elevator computer on a serial bus, one at a time, for gradually replacing the old elevator circuits connectable to a serial communication bus.

Abstract: Method and apparatus for the measurement and tuning of an elevator system including at least one elevator having an elevator car and its control and driving equipment. The method uses at least one computer connected to the system. The elevator system is measured and tuned using virtual measuring and tuning components operated by programs of the computer.

Abstract: A procedure for the tuning of a position controller of an elevator is disclosed wherein an artificial excitation signal is input to the elevator drive system, the response corresponding to the excitation is measured, a mathematical model of the elevator system is calculated, the behavior of the elevator system is simulated, control parameter values minimizing the difference between the target position values and the actual position values are found, individual differences in the vicinity of the ultimate target position are weighted by a large factor, the position control parameter values are reset to optimized values, a real excitation signal is input to the elevator drive system, the model parameters are calculated again, and the above sequence of operations is repeated until the model parameter values and the control parameter values converge.

Abstract: The present invention concerns a procedure for modernizing the control system of a lift group, in which procedure the group control system coordinating the operation of the lifts is renovated and connected to the already existing lift-specific control system. As taught by the new procedure, for each lift is connected one matching computer between the new group control and the apparatus controlling the functions of the lift, and by the aid of which the lift-specific signals are transmitted to the control of the lift and to the group control.

Abstract: This disclosure concerns a procedure for counting the number of stopping objects, such as persons who are coming to wait for an elevator or equivalent. The movements and stopping of the objects are followed by the aid of at least one Doppler radar, whose output signal amplitude changes are used to identify the change of velocity of the objects. The number of objects stopping is calculated from the magnitude of the amplitude changes and/or from the number of Doppler radar pulses recorded.
