Patent SE-513963-C2 (SE)
Inventor: NIINISAARI MATTI ALARIK
IPC: F24F7/08
Filed: 1994-03-08
Abstract: The invention relates to a ventilation-heating unit, comprising one or more heating elements which are supplied with thermal energy from an external heat source. The unit has an outside-air fan, an extract-air fan and a supply-air fan, by means of which supply air is blown through the supply-air nozzles via the heating elements of the unit. The unit is integrated to form a compact aggregate unit including the said fans and the air ducts present between these. In the unit, the pressure side of the outside-air fan is connected to the suction side of the supply-air fan, to which, in addition, the recirculating-air duct belonging to the unit is linked. The flow resistances of the individual inner air ducts of the unit are dimensioned and/or set in such a way that, on the pressure side of the outside-air fan and on the suction side of the supply-air fan, which are interconnected, there prevails a negative pressure which can be set by the unit and is substantially constant at various operating points. The flow direction of the recirculating air (return air) remains directed towards the unit in spite of the different quantities of air varying from one another.

Patent SE-507529-C2 (SE)
Inventor: ANDRE TORE
IPC: G06F17/14
Filed: 1996-10-21
Abstract: The present invention relates to a device and a method for calculating FFT, IFFT or like transforms with the aid of a calculating unit and at least two memories. The calculating unit reads input values from the memory positions in the memories, performs a group of calculations in at least one calculation step, and writes the output values obtained with these calculations into memory positions in the memories. The invention comprises the steps of reading-in and immediately storing the input values for calculation in different groups of calculations. When all input values necessary for a current group of calculations have been read in and the calculations in a preceding group of calculations have terminated at least one first calculation step, calculations in the current group of calculations are commenced. The output values from the current group of calculations are stored intermediately until the output values from the preceding group of calculations have been written, and are then written back into the same memory positions as those from which the input values were read, whereafter the output values can function as new input values. This enables at least two groups of calculations to be commenced at one and the same time.
