20090091287 | Linear Actuator - A linear actuator comprising a spindle nut, where the spindle nut and the spindle between a first and a second point, indicating the length of stroke, can move axially in proportion to each other, depending on whether the spindle or the spindle nut is being driven around via the transmission, and where the position is determined with incremental position sensors, such as at least two Hall sensors or Reed-switches. For determining the position an initiating procedure, where the nut/spindle is moved from a first point on the spindle/nut to a second point on the spindle nut, is carried out, and that the number of pulses from the incremental position sensors appearing by it are registered as a measurement for the length of stroke, and the position is subsequently determined in relation to that. It is noted that the control is active before, during and after the operation of the motor. Hereby, absolute position detection is achieved with incremental sensors, where one formerly was obliged to use rotary potentiometers. Simultaneously an optional determination of the length of stroke and its position and immediate possibility to change the same at any time is achieved. | 04-09-2009 |

20140077742 | LINEAR ACTUATOR SYSTEM WITH MEANS FOR FIRE DETECTION - A linear actuator system comprising at least one linear actuator, a power supply, a control and an operation device. The linear actuator system comprises at least one printed circuit board having multiple layers comprising an electrically conductive circuit. At least one of the layers of the printed circuit board is designed as a detection layer for detecting a leakage current in the electrical circuit, including the electronic components mounted on the printed circuit board. An output voltage is applied to the detection layer, said voltage falling outside of the voltage range in which the electrical circuit works. | 03-20-2014 |
20140126244 | POWER SUPPLY WITH OUTPUT RECTIFIER - The present invention relates to a power converter for converting power from a first voltage level at an input terminal to a second voltage level across an first and second output terminals, the power converter comprising, a first inductor, with one end connected to the input terminal and another end connected to a point with a switched voltage level, a first switch element with a first terminal connected to the point and a second terminal connected to ground and a second switch element connected in series with a capacitor through a first terminal, and a second terminal of the second switch element being connected to the point and the capacitor being terminated to ground, the first switch element is arranged for being operated with a first duty cycle (D), and wherein the second switch element is arranged for being operated with a second duty cycle (1-D), wherein the first and second switch elements are arranged to operated such that their conducting periods are complementary, wherein the switched voltage level at the point comprises of a first pulse generated when the first switch element conducts and a second pulse generated when the second switch element conducts. A magnetic coupled circuit arranged to transform the switched voltage at the midpoint through a primary inductor to a secondary inductor, a first end of the secondary inductor being connected to a first and second diode with opposite polarity, wherein the first diode is arranged to rectify the first pulse and the second diode is arranged to rectify the second pulse and a series connected output capacitor with a common point being connected between the first and second output terminals, the output of the first diode being connected to the first output terminal, the output of the second diode being connected to the second output terminal and the second end of the secondary inductor being connected to the common point. | 05-08-2014 |
