  • System and method for programming using independent and reusable software units
    Patent number: 6851104
    Abstract: A programming implementation providing support for reusable software units built in a hierarchical and modular form. The implementation includes a repository of the reusable software units, where each are arranged to behave independently, communicate transparently, and facilitate creation of new reusable software units.

  • Self-opening entry device for a controlled access area
    Patent number: 5974737
    Abstract: A self-opening and self-closing device enabling entry into a controlled access area includes a gate with two laterally retractable panels that may be opened by inserting a ticket or access card into a control mechanism. Each of the panels is controlled by a respective motor operated by the control mechanism. Each panel is secured to at least two runner members that are each operated by a roller secured to a link arm. The link arms are rotationally interconnected and rotated by the respective motor. Simultaneous rotation of the arms in opposite directions moves the two panels together (or apart) and thus closes (or opens) the entry device by moving each panel into a position in which it is locked by the respective arm in the horizontal position.

  • Inductive position sensor for determining the angular position of a rotating shaft
    Patent number: 5300882
    Abstract: The sensor comprises a field coil generating a time-variant magnetic field, and sensor coils arranged inside the field coil, a rotatable device being arranged for modulating the magnetic flux passing through the sensor coil according to its angular position. Each sensor coil comprises a magnetically permeable core having a polar portion facing the rotatable device. A portion of a magnetically permeable sealing element is arranged facing the rotatable device on the opposite side from said polar portion. The air gaps between said polar portion and rotatable device, and between said portion of the sealing element and said rotatable device, are wholly located substantially within the field coil.

  • Measuring device with several sensors in multiplex
    Patent number: 5211063
    Abstract: A measuring device comprising two or more sensors for one or several values to be measured, these sensors being arranged so as to be connected to an electric power supply and to provide, through output lines, signals which are a function of the value to be measured, the device further comprising transmission and processing devices for the output signals from the sensors.
