Granted: 2005-02-10
Abstract: FIELD: radio engineering; demodulating sixteen-position quadrature-amplitude keyed signals. 
     
     
       SUBSTANCE: proposed demodulator, type KAM-16, has three phase detectors, two solvers, two four-position modulators, three subtracters, adder, amplifier, two multipliers, two limiters, low-pass filter, voltage-controlled generator, and four EXCLUSIVE OR gates. Amplitude difference of demodulator quadrature subchannels is detected and eliminated by subjecting signal to following procedures. Demodulator input signal is decomposed by means of recovered carrier signal into cophasal and quadrature components which are passed through first and second controlled amplifiers, supplied to solver, and tetrad of demodulated characters (A, B, C, D) is obtained at demodulator output. Four-position phase keyed signal is obtained across output of first four-position modulator by means of recovered carrier signal and two digital characters (C, D) out of tetrad of demodulated characters (A, B, C, D). 
     
     
       EFFECT: enhanced noise immunity.

Granted: 2007-04-20
Abstract: FIELD: medicine, surgery. 
     SUBSTANCE: the present innovation deals with detecting the position of appendix in the tissues of abdominal cavity. For this purpose, one should apply two clamps onto a cecum in area of its "tenial part" to lift cecal wall. Then it is necessary to apply a purse-string suture between these clamps and make a paracentesis in its area. An appendicoscope should be introduced into cecal cavity and fixed with purse-string suture. Through appendix' mouth it is necessary to introduce a probe into its cavity under the control of the appendicoscope to lift the appendix carefully. Such a diagnostics enables to decrease traumatism in the course of surgical interference in patients with inflamed appendix in case of adhesive process.
