  • Elevator cage departure monitoring device and method
    Patent number: 9061865
    Abstract: An electromechanical monitoring device for detecting undesired departure of an elevator cage from standstill includes a co-running wheel which when required is pressed against a guide track of the elevator cage, possibly against a running diameter of the speed limiter. A sensor detects rotation of the co-running wheel and actuates a braking device if a rotational angle of the co-running wheel exceeds a predetermined value. This electromechanical monitoring device can be suitable for attachment to or installation in a speed limiter and can be suitable for retrofitting to elevator installations.

  • Method of controlling access to an area accessible by persons, particularly to a space closed by a door
    Patent number: 9064403
    Abstract: A method of controlling access to an area accessible by persons, particularly to a space closed by a door, utilizes at least two communications units for transmitting and receiving an identification code and an access code. The identification code is transmitted at a predetermined first transmission power from a first communications unit to at least one second communications unit. The second communications unit checks the identification code and transmits an acknowledgement code at a second transmission power, which is lower than the first transmission power, from the second communications unit to the first communications unit if the check of the identification code was successful. The first communications unit transmits an access code to the second communications unit. After a successful check of the access code by the second communications unit the access is freed.

  • Load measuring device for an elevator installation
    Patent number: 9056747
    Abstract: An elevator installation includes an elevator cage with a support construction carrying the elevator cage, wherein the support construction has two beams. Mounted on each beam is a positioning arrangement on which, for example, a sensor is positioned, which is part of a load measuring device, wherein the positioning arrangements have material structures or sensor carriers. The sensors detect a change in spacing of the material structures or of the sensor carriers from one another, wherein this change in spacing is caused by a change in loading of the elevator cage. Signals of the sensors are processed in an evaluating unit and a signal representing the loading is used in an elevator control.

  • Method and system for displaying links to search results with corresponding images
    Patent number: 9043268
    Abstract: Methods and systems for displaying search engine results where the file links are displayed with corresponding images of things that fall within a given category are disclosed. Object detection software can be used with a search engine to provide search results to a user that contain specific images found within the result pages (i.e. the pages of the websites returned as the results). For a given class of objects, the user can be presented with images that contain that class of object along with the result hyperlinks, allowing the user to make a more informed choice as to which hyperlink is the most appropriate search result, without being inundated with all of image files present in the result pages.
