Abstract: A device for checking guides of an elevator car that can be moved along guide rails may include means for measuring contact forces of the guides on the guide rails. The device may further include an evaluation unit. The means for measuring contact forces may be configured to make measured values determined by the means for measuring contact forces available to the evaluation unit, either through wired connection or wireless connection. In some cases, the means for measuring contact forces may measure contact forces on the guide rails in at least two different directions. Also disclosed are methods for balancing elevator cars.

Abstract: The present invention relates to a coupling gear device for entraining a shaft door by means of an elevator car door that can be actuated by a door drive for elevator devices, comprising entrainment means (110) provided on the side of the elevator car door and counter entrainment means (210) arranged on the side of the shaft door. The counter entrainment means can be acted on by the entrainment means (110) for entraining the shaft door, wherein the entrainment means (110) and/or the counter entrainment means (210) can be lowered at least partially in the elevator car door or the shaft door.

Abstract: The invention provides a cochlea stimulator for implantation comprising optical fibers of which are coupled to an irradiation source that is controlled by a modulator to generate irradiation specific for a pre-determined range of sound-frequencies. The cochlea stimulator effects a frequency-specific activation of the organ of Corti needed for speech perception especially in noisy environment and more complex sounds. For imparting excitation signals which are generated by modulated pulsed laser irradiation conducted within an optical fiber in order to elicit nervous signals in residual functional organ of Corti sections, the auditory prosthesis preferably contains optical fibers which are dimensioned to terminate in end sections within the cochlea at different sites or sections of the organ of Corti. e.g. having different lengths for locating their end sections at different internal parts of the cochlea.

Abstract: The invention relates to an elevator installation with a number of cars in a shaft, with a second car disposed underneath a first car. Associated with each car is a drive with a traction sheave and at least one cable strand, which is led over the traction sheave and by means of which the car is connected to a counterweight. The second car is kept in a suspension ratio of 1:1 and is connected to its counterweight by means of two cable strands associated with different sides of the second car and led over the traction sheave of the second car. A cable guiding device is provided which subjects the two cable strands of the second car to equal loading.

Abstract: A rope brake for an elevator installation for braking a rope coupled to a car is provided, which has a stop that is immovable in the longitudinal direction of the rope and at least one brake shoe. The rope is led between the stop and the brake shoe, and the brake shoe is adapted to be moved back and forth between a braking position, pressing the rope against the stop, and a release position, releasing the rope. A drive coupled to the brake shoe is provided for releasing the rope. The drive is formed as a linear drive and the at least one brake shoe can be transferred by means of the linear drive into its release position against the action of a braking force acting on it in the braking position. Methods for testing a rope brake for an elevator car having a movable brake shoe are also provided.
