    Abstract: The dynamic system is part of a dynamic apparatus having at least one photovoltaic generator, at least one battery and at least one device for controlling the dynamic apparatus. The method for controlling the dynamic system on the basis of sunlight involves electrically isolating the photovoltaic generator from the battery, reading the short circuit current of the isolated photovoltaic generator, determining a numerical value based on the short circuit current, said numerical value corresponding to the reading of the short circuit current, and comparing the numerical value determined with at least one reference threshold value. When the numerical value determined corresponds to a value range limited by at least one such reference threshold value, the dynamic system is controlled so as to thereon confer a configuration corresponding to the value range.

    Abstract: A linear actuator comprising a spindle, a spindle nut, a transmission, an electrical motor, and an actuation element, is arranged to linearly move the actuation element by means of an interaction of the spindle and the spindle nut, which interaction is being driven by the electrical motor through the transmission. A position of the actuation element, the relative position between spindle and spindle nut, is determined by means of an absolute rotary position sensor and a counter. The counter keeps track of the number of under-flows and over-flows the absolute rotary position sensor generates during movement of the actuation element. A combination of a value from the absolute rotary position sensor and a count from the counter determines the position.

  • Patent number: 8541969
    Abstract: In a method and a device for pulse width modulated (PWM-) activation of an electrical drive motor (2) of an adjustment arrangement based on a reference of the mechanical system of the adjustment arrangement that corresponds to a relationship between the force (F) on the drive motor (2) and the adjustment path (s) or the adjustment time (t) of the adjustment arrangement stored in a memory (9), an anticipated future force value (F(t+t0)) is determined based on the reference of the mechanical system in order to adjust the PWM activation in advance by utilizing this future force value such that motor synchronization fluctuations can be prevented upon anticipated mechanical fluctuations in the adjustment arrangement.

  • Publication number: 20130207584
    Abstract: A linear actuator comprising a spindle, a spindle nut, a transmission, an electrical motor, and an actuation element, is arranged to linearly move the actuation element by means of an interaction of the spindle and the spindle nut, which interaction is being driven by the electrical motor through the transmission. A position of the actuation element, the relative position between spindle and spindle nut, is determined by means of an absolute rotary position sensor and a counter. The counter keeps track of the number of under-flows and over-flows the absolute rotary position sensor generates during movement of the actuation element. A combination of a value from the absolute rotary position sensor and a count from the counter determines the position.

  • Patent number: 8508169
    Abstract: A load control system provides for automatically controlling a position of a motorized window treatment to control the amount of sunlight entering a space of a building through a window located in a façade of the building in order to control a sunlight penetration distance within the space and minimize occupant distractions. The load control system automatically generates a timeclock schedule having a number of timeclock events for controlling the position of the motorized window treatment during the present day. A user is able to select a desired maximum sunlight penetration distance for the space and a minimum time period that may occur between any two consecutive timeclock events. In addition, a maximum number of movements that may occur during the timeclock schedule may also be entered. The load control system uses these inputs to determine event times and corresponding positions of the motorized window treatment for each timeclock event.
