Abstract: A radio receiver system (30) comprises a radio receiver (41), a receiver sample clock (60), which is used for sampling a modulated base-band signal; and a timing correction unit (100). The timing correction unit (100) performs, in the frequency domain, a timing drift compensation between a transmitter sample clock (66) and the receiver sample clock (60). In one example context of implementation, the plural modulated radio frequency carriers have been modulated using Orthogonal Frequency Division Multiplexing (OFDM).

Abstract: The invention relates to simulation of effects in a combat environment, wherein personnel, vehicles and buildings are exposed to simulated fire from military weapons. Direct fire and indirect fire are simulated by means of at least one of light rays and radio waves. Effects of attacking fire are registered by means of a target object device, which includes sensors adapted to detect the light rays respective the radio waves and are co-located with the target object (140). According to the invention the target object is associated to at least one protecting object located between the simulated fire and the target object if such object exists in the current combat situation. This enables a consideration to various protecting object— influence on the simulated fire and the effects on corresponding actual fire.

Abstract: A semiconductor arrangement is provided for generating a predetermined time delay. Two clocks are connected to two parallel, redundant semi-conductor circuits emitting clock signals from multiplexers. The redundant circuits receive delayed clock signals from one of the clocks, and from the other clock, clock signals that are delayed in adjustable delay circuits to be phased in with the clock signals from the first clock. A number of delay elements and a first reference number of delay elements, providing a predetermined delay time, are connected in a reference delay circuit. A quotient of the two numbers is stored. One of the semi-conductor circuits is replaced by an alternative semi-conductor circuit, the reference delay circuit of which is set on the predetermined delay time, corresponding to a second reference number of delay elements. An adjustable delay circuit is set on the same delay time as the replaced semi-conductor circuit by means of the second reference number and the quotient.

Abstract: Manufacturers of extruded profiles have two major problems with the present packaging material, i.e. a too low stability and the fact that the profiles are not separated in the package. Extruded profiles are often manufactured in short series, which puts high demands on short turnaround times, also when packaging the profiles. Another demand is that the products should be packed so as to take up the smallest volume possible. The present invention solves this problem by folding a sheet to form partition walls (B) on which a second insert is resting, so that each profile is completely separated from the others and each layer is only carrying its own weight. The sheet may be folded so that the compartments assume different height and width, both within a layer and between different layers. The stability is obtained by attaching, preferably by gluing, the partition walls, or, alternatively, the folded sheet, on a base plate (A) which may consist of the same material as the partition walls.

Abstract: The invention relates to simulation of effects in a combat environment, wherein personnel, vehicles and buildings are exposed to simulated fire in the from military weapons. Direct fire and indirect fire are simulated by means of at least one of light rays (111) and radio waves (121). Effects of attacking fire are registered by means of a target object device (145), which includes sensors adapted to detect the light rays (111) respective the radio waves (121) and are co-located with the target object (140). According to the invention the target object (140) is associated to at least one protecting object (130a; 130a′) located between the simulated fire (111; 121) and the target object (140) if such object exists in the current combat situation. This enables a consideration to various protecting objects' (130a; 130a′) influence on the simulated fire and the effects on corresponding actual fire.

Abstract: The figure shows a unit (5) for distributing clock signals (SA1, SB1) in telecommunication systems. The unit is provided with a semiconductor arrangement (ADA, CTA, RDA) for generating a predetermined time delay. Two clocks (CLA, CLB) are connected to two parallel, redundant semi-conductor or circuits (SCA, SCB) emitting clock signals (SA2, SB2) from multiplexers (MXA, MXB). These receive delayed clock signals (SA1) from one of the clocks (CLA), and from the other clock (CLB) clock signals (SB1) that are delayed in adjustable delay circuits (ADA, ADB) to be phased in with the clock signals (SA1) from the first clock Thus, a number of delay elements in the delay circuit (ADA) are connected and a first reference number of delay elements, providing a predetermined delay time, are connected in a reference delay circuit (RDA). A quotient of the two numbers is stored.
