Patent SE-8406025-D0 (SE)
Inventor: WALLIN SVANTE
IPC: G02B6/32
Filed: 1984-11-29
Abstract: Incoming light is reflected and bent through 90 deg. from its original direction by a flat mirror. The light then comes in contact with a focussing mirror in a direction which coincides with that normal for the centre of the curved, mirroring surface. The distance between the two mirrors is selected so that the focus of the focussing mirror coincides with the centre of the flat, mirroring surface. At this point, a hole is drilled through the flat mirror at an angle of 45 deg. This permits the end of a fibre or a detector to be positioned in focus. The arrangement may be used in a reversed manner, i.e a divergent light source is placed in the hole, whereby the emitted light remains parallel. The distance between the mirrors may be varied by one mirror being rotated relatively to the other around an axis coinciding with that of the hole.

Abstract: Sensor device for measuring the speed of wheeled vehicles. Two elongate sensor elements (26, 27; 28, 29) are placed substantially transverse a roadway and are connected to equipment (14) for measuring the time difference between the signals generated when the hoses are passed over by vehicle wheels. The sensor elements which are used are mutually joined along their entire length by a stiff web formed such as to define spacing between the sensor devices which is constant and independent of the passage of the vehicles. This spacing is in the order of magnitude 10-100 mm, i.e. very much less than the width of the roadway.

Abstract: A receiver removes a direct current (DC) offset component from a received Code Division Multiple Access (CDMA) spread spectrum signal. The DC offset is attributed to both spreading code imbalance as well as conversion between analog and digital formats. In operation, received data is de-spread using an appropriate de-spreading code. Thereafter, a DC offset removing circuit employs a positive/negative counter counting each occurrence of positive and negative chips to produce a chip imbalance for each chip in the spreading code. The measured imbalance is multiplied by the received data signal, an RF component of this multiplied output is removed by a low-pass filter, and thereafter, the signal is again multiplied by the chip imbalance. The DC offset components in the received signal are removed by subtracting the second multiplied signal from the received data signal.

Abstract: The present invention relates to a method for commercial edible fish rearing of Euro-asiatic pike-perch, Stitzostedion lucioperca. By means of the method the intestinal system of the pike-perch is made to accept and to assimilate the energy in a dry feed. This is done in that mature, fertilised pike-perch spawn is released into a hatching tank containing rotifera, where it is allowed to hatch, following which a smaller quantity of Cladocera and Copepoda is added to the hatching tank. The pike-perch is thereafter allowed to feed in the hatching tank, initially on rotifera and then on Cladocera and Copepoda, until the pike-perch larvae have left the larva stage and passed to a fry stage and reached a length of approximately 25-35 mm, following which the fry are transferred to a rearing tank. In the rearing tank accustomisation to dry feed is begun, following which rearing to a stage at which the fish are ready for killing is undertaken with dry feed as the sole source of nutrition for the fish.
