  • Patent number: 9608557
    Abstract: The present invention relates to a method for controlling operation of an electric motor in a height-adjustable furniture arrangement, wherein operation of the electric motor provides a height-adjusting function in the height-adjustable furniture arrangement. The method comprises the steps of providing, by a power supply unit connected to the electric motor, an incoming power comprising an incoming current and an incoming voltage, transforming the incoming current and the incoming voltage to a motor supply current and a motor supply voltage supplied to the electric motor, measuring load on the electric motor, and when the measured load requires a current higher than the incoming current for providing the height-adjusting function, setting the levels of the motor supply current and/or the motor supply voltage such that the motor supply current is higher than the incoming current and the motor supply voltage is lower than the incoming voltage.

  • Patent number: 8967006
    Abstract: A linear actuator (1), comprising a threaded spindle (10) with a longitudinal extension along a longitudinal axis (X), the spindle (10) having a right hand thread (11) and a left hand thread (12), both threads provided over a common longitudinal length of the spindle, the spindle (10) being adapted to be rotated by a driving device (60). The linear actuator further comprises a first nut member (20) provided with a right hand thread (21) and a second nut member (30) provided with a left hand thread (31). The first and the second nut members (20, 30) are in threaded connection with the spindle (10) in such a way that rotation of the spindle provides opposite linear movement of the nut members (20, 30) relative to each other along the longitudinal axis (X). Thereby, a linear actuator is provided with three parts that all move linearly relative to each other during rotation of the spindle.

  • Patent number: 5676154
    Abstract: A method, a device and a sensor to sense the breathing of a man or an animal. A breathing sensor which, in an optical way, detects changes in deposited moisture on a sensor portion is placed in the breathing air flow, and changes of a transmitted or reflected optical signal dependent on deposited moisture is sensed as a measure of the breathing. A sensor according to the invention may consist of an optical fiber, one end surface of which constitutes a sensor surface and reflects a signal in the fiber to a varying degree dependent on mist deposited by the breathing air flow on the sensor surface. The sensor can be used in other environments as well, to detect a condensable vapor in a gas.
