Abstract: A linear actuator comprises a reversible electric motor (2) which, via a transmission, is capable of driving a spindle (4) having a spindle nut (5) secured against rotation and comprises a power supply and a controller. The actuator moreover comprises a memory unit for collecting at least one set of data from the operation, indicating how long and how hard the actuator has worked. It is hereby possible to obtain an overview of the mechanical state of the actuator and thereby prevent unfortunate occurrences and accidents as a consequence of wear-out of the actuator.

Abstract: A linear actuator includes a housing with a reversible DC-motor, which through a transmission can displace an activation element between two end positions, where an further switch located in the longitudinal direction of the spindle is activated and deactivated when a spindle nut passes during its travel on the spindle and provides information for a calculation model which continuously calculates the position of the spindle nut on the spindle so that the calculation model in the positions where the further switch is activated by the spindle nut is calibrated to show an absolute position which is entered as a reference point in the control.

Abstract: Today, electromechanical actuator systems are used in a variety of applications, of which some are more safety critical than others. Likewise, they are used in a wide range of applications where the safety of persons often to a higher or lesser extent depends on that the actuators remains safe both during normal use and in the fault conditions, which may occur. By an actuator comprising a DC motor (2) equipped with a worm drive and a spindle (4), the typical wearing components are the bearing, which carries the spindle (4), the spindle nut (5) and the worm wheel (9) in the worm drive. Common to the described defect situations is that they in the time leading up to the occurrence of the defect will show a decrease in the ratio of efficiency. Whether it is the spindle bearing, the worm drive, the spindle nut (5) or for that matter the motor, which is getting worn, the proportion between the current which the motor absorbs and the force the actuator performs will change.

Abstract: An actuator comprising a reversible electric motor, which over a gearing, drives an activation element which can move back and forth. The activation element is of the non-self-locking type. Furthermore the motor and gearing are of a non self locking type. A brake holds the activation element in any position, when the electric motor is inactive, said brake can be released by means of a release mechanism. The motor is used as generator when the brake is released and the generator voltage from it is used to adjust the velocity of the activation element. Thus, a quick release is provided, where the activation element can be disengaged and adjusted evading gear and motor, and where the movement of the activation element, during the disengagement, occurs with a controlled velocity.

Abstract: The invention relates to a communications method of communicating states from an activation unit to a receiver via a communications bus, wherein the state may be activation/deactivation of an activation unit, and wherein the state is communicated to the receiver via a serial data stream timed by a clock signal, said data stream transmitting data packets which comprise an identification part and a data pare wherein: ? the identification part comprises a plurality of bits which identify which activation units the data packet concerns, and ? the data part comprises a plurality of bits which individually identify the state of an activation unit. The invention also relates to a system based on the communications method and comprising an activation unit and a receiver. In addition, the invention relates to an activation unit and a receiver.

Abstract: A control for ensuring periodical servicing of articles of hospital and care furniture (1). The control is based on the cleaning of the article of furniture and recaptures the number of cleanings in a counter. The signal for the counter is initiated either by manual activation when the piece of furniture has been cleaned, or automatically when the piece of furniture (1) is driven out of the automatic washer apparatus (2). In a special embodiment a thermo sensor is used to detect that the article of furniture is being cleaned. An indication of the requirement for servicing is triggered and shown in an indication panel (24) when the number of cleanings exceeds a preset number.

Abstract: An electrical actuator system, especially for hospital and care beds and patient beds, comprising a number of actuators (6,7; 10,11), a control box (12) with a mains-based power supply, and typically also a rechargeable battery package and a control unit with a microprocessor, a number of controls (15,16), an orientation light (17) for mounting under the bed. The system comprises at least one junction box (13,14) and the orientation lighting is, with its own control unit, located in this. This enables a flexible location of the lighting.
