    Abstract: A method and apparatus for compensating for nonlinearities in a non-linear device for manipulating a signal is described. Shortly before an initial discrete power increase is applied to the device, a first pre-distortion function is generated on the basis of a first set of DPD parameters and applied to the signal before it reaches the device. A predetermined time period after the initial power increase, the first pre-distortion function stops being applied to the signal, and a second pre-distortion function is generated on the basis of a second set of DPD parameters and applied to the signal. Shortly before a subsequent discrete power increase is applied to the device, the first pre-distortion function is generated on the basis of the first set of DPD parameters and applied to the signal.

    Abstract: A pull-out mechanism for mounting a drawer in a drawer cavity of a piece of furniture. The mechanism may include an upper pull-out rail with a substantially U-shaped cross-section affixed to the drawer and may optionally include a lower rail with a substantially U-shaped cross-section affixed to a wall in a drawer cavity. The mechanism may also have an intermediate rail, which is disposed between the upper rail and the lower rail, or alternatively may support the upper rail while attaching to the wall. One or more bearing holders provided with at least one ball bearing and a plurality of rollers or wheels supports the upper rail and optional lower rail in a mounted relationship with the intermediate rail.

    Abstract: A device for use in connection with a “soft” opening and later “soft” closing of a drawer in a furniture body. One or more rails (2, 3, 4) are mounted between the drawer and the furniture body. The device comprises a single, oblong, partly open housing (1) delimited by a first end member (7a) and a second end member (7b). The housing (1) is mounted on a furniture body or on a rail (2) secured thereon. A longitudinally displaceable damper cylinder (9) is mounted in said housing (1), said damper cylinder comprising a piston (8) with a piston rod (10), said piston (8) being provided with an auxiliary valve (37, 38). A first end part (9b) of the damper cylinder (9), and which is free of the piston rod (10), has an outer abutment face against which a first offsetable pin member (15), which is mounted substantially at the rear end of the drawer or on a longitudinally displaceable rail, abuts when the drawer is opened, while a second offsetable pin member (13), which is mounted substantially at the front end of the drawer, abuts a third end part (12) mounted on the outermost end of the piston rod (10), when the drawer is displaced towards the closed position thereof; the first end member (7a) and the second end member (7b) of the housing optionally being provided with a slot-like opening, (7a′) and (7b′), respectively, through which the first pin member (15) and the second pin member (13), respectively, optionally can pass in and out of the housing (1). In this way, a structurally very simple device is obtained, which can provide both a soft opening and a soft closing of the drawer in the furniture body.

    Abstract: A pull-out mechanism for a drawer (2) in a drawer cavity (3) in a piece of furniture (4). The pull-out mechanism includes an upper rail (8) with a substantially U-shaped cross-section, said rail being affixed to the drawer (2) in its longitudinal direction, and possibly a lower rail (8) with a substantially U-shaped cross section, said lower rail, possibly indirectly, being affixed to a wall (5) in the drawer cavity (3), and an intermediate rail (10) which in its longitudinal direction is movable between the upper rail and the lower rail. At least one bearing holder (12, 22) with roller (14, 15, 24, 25) and balls (16, 29) is inserted between the intermediate rail and the upper rail and the lower rail respectively. Exactly one bearing ball (16, 29) is mounted in the part of the individual bearing holder (12, 22) placed on one side of the intermediate rail (10); two rollers or wheels (14, 15, 24, 25) are mounted in the part of the individual bearing holder (12, 22) placed on the other side of the intermediate rail (10). The axes of rotation of said rollers or wheels are placed in each their plane of two planes standing perpendicular to each other. A substantially horizontal auxiliary roller (18, 28) extending to both sides of the intermediate rail (10) is mounted in the individual bearing holder (12, 22) between the intermediate rail (10) and the upper rail (6) and the lower rail (8) respectively. Hereby a considerably constructive simplification is achieved and the pull-out mechanism can bear both horizontal and vertical loads in a reliable way. Furthermore it is possible to pull out the drawer to a position just outside the actual piece of furniture.

    Abstract: Device for securing a soft ending of the opening movement of a drawer as the latter is drawn towards an outer limit stop (10), the drawer being mounted in a (not-shown) furniture body and capable of being pulled out from said body, and in which there may be one or more rails (1, 3) between the drawer and the furniture body. The device comprises a damper (6) filled with a fluid medium attached to the furniture body—or to a rail of the furniture body—and a piston with a piston rod (7) being reciprocable in said damper (6), the free end of the piston rod (7) being attached to a tilt-able rocker (9). Whenever the piston rod (7) close to its outermost position is moved in and out in the damper (6), the rocker can be moved on a guide portion (17)—mounted at the damper (6)—between a first end position (FIG. 2) close to the damper, in which a first pin (19) mounted at the back of the drawer may engage with the rocker (9), and a second end position (10) far from the damper (6), in which the piston rod (7) is in its outermost position. This device can work in an especially reliable way.
