Abstract: An arrangement is adapted to determine an estimate for mineral density related to a patient's first bone, wherein said first bone is associated with a femoral head, neck and/or a lumbar spine. The estimate determined by determining a first parameter, which is related to a property change in a measurement signal, most preferably an ultrasonic signal, launched towards some second bone of said patient other than the first bone after the measurement signal has been in interaction with said second bone. This is followed by determining an estimate for mineral density related to said patient's first bone by using said first parameter.

Abstract: The present invention relates to a method for activating actions. The method comprises the steps of defining an action, a portable device (9) related to it and, as a condition for activating the action, at least one item of position data, and determining the position of the portable device (9). When the position of the portable device (9) corresponds to the position data defined in an action, said action is activated. In the method, the information about actions is processed in a server (2), from which a data transmission connection can be set up to the device, in which the action data is transmitted from the server (2), to be activated.
