Inventor: HULTEN STIG OLA
IPC: G02B6/24
Filed: 1991-04-03
Abstract: The end region of the fibre to have its relative characteristics determined is heated e.g. by electric discharge to such a temperature that an observable amount of light is produced, with the light emitted during the heating process recorded as a picture. The picture is analysed to determine the light intensity emitted from all points in at least one line perpendicular to the longitudinal direction of the fibre, as viewed in a chosen direction. The determined light intensity profile is analysed further to obtain a particular characteristic property of the region of the fibre. The heating of the end fibre is normally performed before splicing the fibre end to another fibre.

Abstract: A method for position finding of an automated guided vehicle using detection of angle positions for anonymous reflectors (R1-R11). The anonymous reflectors are arranged in positions in a limited transport area, and the positions are stored. A concentrated beam (B) is emitted from a vehicle (10) and is made to pass over a search sector. The angle position in relation to a reference direction (D) of the vehicle (10) in reflective objects is continually detected during the sweep of the beam over the search sector, and corresponding angle values are determined. Initially the following measures are taken for association of the angle positions to physical reflectors, and for determination of the position of the vehicle (10); i) at least three angle values with a suitable distribution over the search sector is selected, ii) the angle values are associated to reflectors and a position is determined for the vehicle on the basis of the known position of the assumed reflectors, iii) if the vehicle position determined in this way is within a certain part of the transport area the other angle values are associated to reflectors, iv) for each angle value, existing deviation is determined between detected angle values and angle values expected between the vehicle position and known reflectors, v) the measures taken are repeated for each possible combination of selected angle values. A combination of associations with the best possible agreement on the vehicle position is selected, whereby the position and direction of the vehicle is determined.

Abstract: The invention relates to a soil heat exchanger comprising at least one deep, cylindrical hole (1) in the soil and a heat transferring liquid circulating in a closed system with a central, heat-insulated leg (2) and a surrounding outer leg (3) in the soil hole. The outer leg (3) should make a good thermal contact with the wall of the soil hole (1), which up to now has been difficult to achieve with respect to the difficulty in feeding down the outer leg without being damaged. A solution is obtained according to the invention consisting in that the outer leg (3) is manufactured with a stable condition in which it is radially retracted. It is further designed such, that when the two legs (2, 3) are fed down into the soil hole in the end position the outer leg can be influenced to be radially expanded by water fed down under pressure in channels (12) of the outer leg.
