Abstract: The present invention concerns a device (1) for preloading of a rewind mechanism (2) for a fabric (4) arranged on an elongated tube (3) or the like of a roller blind, a projector screen or the like. The rewind mechanism (2) is arranged to be essentially inserted into said tube (3) and includes a spring (10), that is tensioned when the fabric (4) is rolled out and relieved when the fabric (4) is rolled up onto the tube (3). The device (1) includes an outer mounting element (5), that is arranged to be attached to the tube (3), and an inner mounting element (6), that is arranged to be attached to an outer bracket (not shown), said mounting elements (5, 6) being rotatingly arranged in relation to each other about a longitudinal axis of said tube (3). A spring element (7) is arranged between said mounting elements (5, 6) and includes a sleeve (11), in which said spring (10) is arranged.

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 pallet consisting of a deck (1) and a number of feet (3a, 3b, 3c, 3d) placed under the deck. When the deck is loaded with goods (5) for transport the pallet is covered with a soft covering material (4). The latter is made from plastics or textile and removably fastened to the deck (1) at least at one place by wedging a corner (4a) of the covering material tight in at least a first incision (9) in at least one clamp (7) mounted on the deck (1). It is thus obtained that the goods loaded on the pallet may be securely covered and held in place on the pallet; the pallet becoming relatively easy to handle.

Abstract: A pallet (1) made of plastic or other materials is provided with a plurality of hollow feet (2, 3, 4, 5, 6, 7, and 8) at its underside (10). These are obtained by depressing the pallet material. At least one of these feet—foot (8)—has a length (L?) substantially corresponding to the length (L)—or width (B)—of the pallet. This foot (8) contains at least two inner comparatively wide support parts (13, 14, 15), arranged in series and projecting from the bottom part (16) of the foot (8). In this way, according to fire tests—where several identical pallets (1) filled with goods were stacked on top of each other—each pallet (1) has a unique ability to extinguish flames generated in goods on the pallet located directly below the pallet in question, and moreover, the pallet also shows considerable dimensional stability. This makes the pallet (1) particularly suitable for transport on transport means, optionally roller conveyors which cause many bumps.

Abstract: A calf rest is provided for a patient chair. The calf rest may comprise a plate-shaped calf rest pad and a mounting is be mounted on the patient chair by means of a joint arrangement. The joint arrangement may be designed so that the calf rest pad is movable between an inactive moved-away end position, in which the extent of the calf rest pad is substantially parallel to one side of the patient chair and the calf rest pad can be positioned close to the patient chair, and a second active end position, where the calf rest pad is capable of supporting the patient's legs when extended, outwards away from the patient chair.

Abstract: The present invention relates to an interactive method of presenting information in an image to a user, who carries a head-mounted display device (2+5, 27), which presents an image of the surroundings (3, 9, 25). The method comprises that the user's head position and direction are established in relation to the surroundings and that a calculating device (7) 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 hierarchical scheme the user is positioned as regards information about and performed operations concerning that part of the surroundings which is positioned in front of the user's head and, based on this, which information is to be presented to the user and presents this in the form of a virtual image which is mixed with the real image. The user studies the information and, where required, performs the current operations.

Abstract: A patient chair is provided that includes a chassis with a frame, a seating device intended for a patient and connected to the chassis, and a driving device for moving the seating device relative to the frame in the vertical direction between a lower position and an upper position, wherein in the upper position the seating device and, thus, a patient sitting in it are inclined backwards relative to the lower position. In one implementation, a stand belonging to the chassis extends upwards from the frame, and an element connected to the stand is continuously arched. Means cooperating with each other and positioned on the stand and the seating device are arranged for guiding the seating device along the element in the movement of the seating device between the lower and upper positions, so that the seating device is continuously gradually tilted in the course of its curved movement in the vertical direction.

Abstract: An apparatus for facilitating, in handicapped patients, undressing, dressing and access to body parts between the waist and knees of the patient. The apparatus includes a seat (20) and a back support (10) which between them form an open region (11) in which a person located in the apparatus is not supported. The seat and the back support are disposed to be displaced between positions in which the person is placed in positions where the major proportion of the patient's weight is carried by the seat or in which the major proportion of the patient's weight is carried by the back support.

Abstract: An implantable device for occluding a body duct, especially a blood vessel. The device includes a flexible, elongate plate to be fixed around the duct, a plurality of communicating bulbs which are arranged on one side of the plate and have a variable volume, and a connection for supplying fluid to the bulbs for occluding the duct and for evacuating fluid from the bulbs to open the duct after the occlusion. The flexible plate has a perforation at one end and a locking member in the form of a thickened portion at the other end. The locking member is passed through the perforation for safely fixing the device around the body duct.To improve the occlusive function of the device, the bulbs may be made of an elastic material, the thickness of which is smallest at the tops of the bulbs.
