A message transport network (10) is provided for high speed switching between processing elements (72, 80). Clusters of low speed processing elements (72) may be connected to the message transport network (10) through a transport node controller (78). The transport node controller (78) and the high speed processors (80) are connected to the gateways (82). A pair of gateways (82) may be connected t...

A radar warning unit is installed in the aircraft, and records the position and type of anti-aircraft units on the ground beneath its path towards a target, where the units also use radar. The areas of effect of the units are assessed, taking account of the aircraft relative position, course and speed. An optimal path for the aircraft is determined from such areas of effect, and the requisite mano...

The present invention relates to a method and an arrangement for preventing unacceptable temperature variations in spaces 2 with electronic units 3, the components of which give off heat during operation and are sensitive to large and/or sudden temperature variations. In order to ensure accurate control of the cooling function without having to use a water cooler, cool night air is made to flow to...

Keyring opener comprising a metal plate 1 shaped such that the ends 5 of a keyring 2 can be lifted by a turned- up part 3 in the metal plate 1 to allow the said plate to be threaded onto the ring 2. In the metal plate 1 there is additionally disposed a knife-like part 4 having an edge 6 for use when keys are put onto and removed from the ring 2. It is also easy to make a recess 7 in the said plate...

The invention relates to a snowmobile sledge in which the passenger compartment 4,5 is situated between a resilient fastening device 9 and two runners 7a,7b connected behind the passenger compartment. The fastening device is situated at such a height that in normal running it is the runners 7a,7b which support the snowmobile sledge whilst the passenger compartment is resiliently suspended between ...

The monitor receives the pulsated output signals from the dipole in different projections. As dipole, positive and negative electrodes are used, over which a DC voltage or a slowly alternating voltage is applied. On this voltage, short voltage pulses are superimposed as pulsated output signals from the dipole. The voltage selected is between 0 and 30 volts, and the dipole output signal uses voltag...
