Abstract: A method for adaptive compensation of a temperature drift of a sensor, designed to measure the torque of a shaft or a drive train or the force in mechanical equipment during operation. A sensor signal is recurrently measured. An associated temperature is determined. An offset value is calculated as a function of temperature based on measured and stored data. The measured signal value is compensated using the calculated offset value. When the sensor is unloaded or nearly unloaded is detected. When the sensor is unloaded or nearly unloaded the signal sensor signal value and the associated temperature value are stored in a memory and a model of the sensor offset is updated. A system and computer program product for adaptive compensation of the temperature drift of such a sensor signal offset.

Abstract: An apparatus for estimating or supervising one or more internal mechanical properties of a metal alloy object with a known chemical composition based on the resistivity of the metal alloy object. The apparatus includes a device for measuring the resistivity of the metal alloy object, and a computation unit adapted to calculate the content of dissolved alloying elements in the metal alloy object based on the measured resistivity and the known chemical composition of the metal alloy, and based thereon to calculate at least one internal mechanical property of the metal alloy object.
Abstract: A control system for controlling one or more manipulators. One or more drives control motors driving the movements of the manipulator. An axis computer provides control signals to the drives. A main computer is adapted to execute a program with instructions for the movements and supplies the axis computer with control instructions. Physically separated modules are adapted to be placed at separated locations and to handle different functions. Each module may be surrounded by a casing of its own, may have its own power supply and has a well-defined interface in relation to the other modules. The computers and drives are arranged in the modules. One of the modules is a main computer module, which comprises the main computer. Another of the modules is a drive module, which comprises the axis computer.

Abstract: A control system for controlling the movements of a plurality of mechanical units. The control system includes a program that includes a plurality of mechanical unit programs. Each program includes movement instructions for at least one of the mechanical units. The control system also includes a plurality of path planners. At least one of the path planners is adapted to receive instructions from more than one of the mechanical unit programs and on basis thereof determine how the mechanical units should move in order to synchronize their movements. The control system further includes switches adapted to switch a mechanical unit program from one path planner to another, whereby the movements of the mechanical units are synchronized when their mechanical unit programs are connected to the same path planner and the movements of the mechanical units are independent when their mechanical unit programs are connected to different path planners.
Abstract: An installation for transmission of electric power via a high-voltage ac voltage line between two switchgear units located at a large distance from each other. For the transmission of the electric power, the ac voltage line includes at least one extruded cable with an inner electric conductor, an insulating layer of a solid material surrounding the conductor, and an outer screen layer located at ground potential. The installation also includes one or more inductors located along the extent of the cable between the switchgear units and integrated into the cable.
