Title: Log-polar signal processing

Filed: 1989-08-02
Granted: 1996-01-09
Abstract: The invention relates to a method and an arrangement intended for radio communication systems and effective in digitalizing and subsequently processing numerically arbitrary radio signals. The signals are represented by composite (complex) vectors which have been subjected to disturbances in the system, such that information in the signals has been lost. This information is restored in its entirety when practising the present invention. For the purpose of solving this problem, the inventive digitalizing arrangement includes a multistage logarithmic amplifier chain (A) in which each stage is connected to a separate detector (D), the output signals of which are added in an adder. The adder output signals are then transmitted to a first A/D-converter (AD1) for digitalizing and converting the amplitude components of the signal. At the same time, the undetected signal from the saturated output stage in the amplifier chain is transmitted to a second A/D-converter for digitalizing and converting the phase components of the signal. The digital values obtained on the outputs of the AD-converters (AD1, AD2) are applied to different inputs of a digital signal processor (MP) for numerical processing of the pairwise received digital values in a manner such as to restore the complete vector characteristic of the signal.

Abstract: With the aid of known measuring vessels, which are used for receiving fluids to be examined, such as blood, blood plasma or the like, the coagulation of blood is determined mechanically. However, a photometric measurement of the coagulation is not possible with these known measuring vessels, which are provided in the centre of the circular base area with a projecting delimiting journal, since for this a complete and uninterrupted passage of the light emerging from a transmitter through the wall of the measuring vessel is indispensable. 
<??>The aim of the invention is to provide a measuring vessel with which both a mechanical and a photometric determination of the coagulation of blood is possible. 
<??>This aim is achieved by virtue of the fact that the measuring vessel (1) has a rectangular shaft (4) whose one end is of funnel-shaped design and opens into the tubular part (7) which has two parallel side surfaces (9), which in each case form a plane contact surface. In this case a foot element is connected to the tubular part (7), onto which foot element the measuring vessel (1) can be placed. 
<??>By means of this design of the measuring vessel it is now possible to carry out photometric analyses over the entire spectral region. However, at the same time the measuring vessel can also be used for examining the blood according to the ball method.
