Abstract: The present invention refers to a motor saw arrangement comprising a support plate attached to the motor saw chassis or motor saw motor, a detachable clamping plate and a detachable guide bar arranged between the support plate and the clamping plate. The support plate is provided with two first recesses and at least one threaded hole, while the clamping plate is provided with two protrusions adapted to fit inside the respective two first recesses when the clamping plates is attached to the support plate and the protrusions each have a height that exceeds a corresponding height of the guide bar. The guide bar is provided with two keyhole-shaped slots and with a longitudinal slit between the two keyhole-shaped slots and the support plate is further provided with an alignment means. The invention further relates to a method to remove and/or replace a saw chain from a guide bar and to a guide bar intended and adapted for the motor saw arrangement described herein.

Abstract: A method for producing a lithium insertion material including the steps of: providing an iron containing compound, a lithium containing compound and a silicate containing compound; providing a solvent; subjecting the compounds in said solvent to dissolution; obtaining precipitate; and filtering the obtained precipitate from the solution and subject the precipitate to washing and drying.

Abstract: A method for a user to navigate in a surrounding world captured by one or more image sensors and displayed to the user in an image display area of a display device which in use is in front of the user's head and follows the movements of his head. When the user's head is directed in an area which the user can easily reach by turning his head, the display is controlled by his head direction. When the head direction reaches the edge of what the user can reach by turning his head, use is instead made of controlling by gaze direction of that displayed, in which case the point of the surrounding world pointed out by the gaze direction is continuously placed in a predetermined area of the image. The change occurs either automatically by the user's gaze direction being at the edge of the image display area or by a command, for instance with the user's voice or a motion of his hand.

Abstract: An interactive method of presenting information in an image to a user, who carries a head-mounted display device that presents an image of the surroundings. The user's head position and direction are established in relation to the surroundings and a calculating device establishes, based on this, which part of the surroundings is positioned in front of the user's head. Furthermore, the calculating device establishes where in a chain of information the user is positioned and, based on this, presents information in the form of a virtual image which is mixed with the real image. A central part of the image is then defined and fields and/or objects outside this area are shown in a non-disturbing way until the user's gaze has left the central part. The user informs the calculating device that he/she has received the information and, respectively, performed the current operations by looking at the fields/objects.

Abstract: A device for screening interfering radiation from a radiation source from reaching a radiation receiver. The device includes a sensing device determining the position and orientation of the radiation receiver relative to the radiation source; a matrix, positioned in front of the radiation receiver, of elements which can adopt a varying transmittance and which cover the solid angle within which it is desirable to screen interfering radiation; and control equipment which calculates in what position relative to the radiation receiver a radiation obstacle is to be placed to be able to screen the radiation source and which controls the elements of the matrix in such a manner that the matrix forms a partial or complete radiation obstacle in the estimated position.
