Abstract: Method for providing reduced interference for at least two co-located FMCW (Frequency Modulated Continuous Wave) Doppler radars, each of said radars being used in a system to detect respective distances to and velocities of objects moving through space, can include a propagation determination step, in which expected electromagnetic wave propagation times are determined between pairs of radars; a sweep time offset synchronizing step, in which different respective sweep time offsets are selected, with respect to each radar in a first group of radars; and a sweep frequency offset synchronizing step, in which a second sweep frequency offset is selected with respect to a second group of radars, the second sweep frequency offset being relative to a sweep frequency pattern used for radars belonging to said first group. The invention also relates to a system and to a computer software product.

Abstract: The invention relates to a fraction collector apparatus (1; 1?) for positioning at least one fraction collector nozzle (4), comprising a frame (2) arranged for guiding the at least one nozzle (4) to different positions (22) in order to collect and dispense fractions (6) of a substance to or from containers (8). At least one track (10) is arranged in the frame (2), and in which at least one track (10) an endless movable transporting means (12) is arranged; on which transporting means (12) the at least one nozzle (4) is attached; a first actuating means (18) is connected to said transporting means (12) for actuating said transporting means (12) in the track (10), so that said at least one nozzle (4) is movable in different positions (22) along said track (10). The invention also relates to a method of positioning a fraction collector nozzle (4) by means of such a fraction collection apparatus (1; 1?).

Abstract: The present invention refers to a method for preparing a superhydrophobic surface on a solid substrate comprising the steps of (a) providing a solvent in the form of a pressurized fluid in a vessel, wherein the fluid exhibits a decrease in solvency power with decreasing pressure; (b) adding a hydrophobic substance to the solvent as a solute, which substance is soluble with the pressurized fluid and has the ability to crystallize/precipitate after expansion of the fluid, thereby obtaining a solution of the solvent and the solute in the vessel; (c) having at least one orifice opened on the vessel, thereby causing the pressurized solution to flow out of the vessel and depressurize in ambient air or in an expansion chamber having a lower pressure than within the vessel, the solute thereby forming particles; and (d) depositing the particles on the substrate in order to obtain a superhydrophobic surface.

Abstract: A photonic device has a semiconductor substrate with an active photosensitive surface generating a photocurrent dependent on the intensity of light falling on it. A light emitting element, typically a VCSEL, having a lower electrode is located on a contact element in the middle of the active surface. The light emitting element covers the contact element. A doped conductive path within the substrate establishes electrical connection between the contact element and a peripheral bonding pad. The doped path preferably constitutes the entirety of the upper layer forming the photosensitive surface.

Abstract: A locking device to be secured in a weapon, comprising a first locking means manoeuvrable by a lock cylinder (56), which locking means has a friction body (10) displaceably arranged in relation to the lock body (3-5) and insertable into the chamber or barrel of the weapon, and blocking elements (23) arranged to be moved into engagement with the inside wall of the chamber/barrel in case of mutual displacement between the friction body (10) and the lock body (3-5). The locking device furthermore comprising a second locking means (73), which by means of the lock cylinder (56) is movable into engagement with a space in the weapon located adjacent to the chamber/barrel in order to secure the locking device in the weapon.

Abstract: A photodetector includes a detector responsive to incident light to generate an output signal and one or more band gap filters upstream of the broadband detector for absorbing incident photons of predetermined wavelength. The bandgap filters have a bandgap gradient across their width. The photodetector can act as a selective detector without the need for a separate optical filter.

Abstract: A machine intended for back muscular training includes a seat (2) carried by a stand, a back rest (17) situated above the seat, as well as a main arm (12) which is turnable around a main joint (13) against the effect of a loading device (3). The back rest (17) is spaced from the seat and connected to a part of the main arm (12) extending upwards from the main joint (13), more precisely via a rocker arm (19) turnable around a secondary joint (20) on the main arm, which rocker arm has a cross boom (18), extending at an angle to the same on which the back rest is mounted. In this way, the back rest (17) is movable between a front starting position and a rear end position in an orbital path along which the back rest—thanks to the mounting thereof on the rocker arm (19)—can move freely between different radial positions in relation to the main joint (13) depending on the individual back flexing movements of individual users.

Abstract: A medical article is made non-thrombogenic by means of a surface coating containing heparin. The heparinized surface is stabilized by being contacted first with a cationic surfactant of the primary amine type and, subsequently, with a dialdehyde.
