Abstract: Substituted sulphonamides having the general formula (I) and salts, hydrates and solvates thereof were prepared and described, wherein R1 is CO or SO2 and R2 is NH or O and where R represents linear or cyclic aliphatic chain and n represents number of linking aliphatic chain carbons (n can be 0, 1, 2 or 3), which are useful in the manufacture of the medicaments due to the carboanhydrase inhibition. These compounds are prepared by nucleophilic reaction of an amine with 4-sulfamoylbenzenesulphonyl chloride in the presence of triethylamine excess in tetrahydrofurane or in ether at temperature 0 to 20° C. The compounds show an antiglaucomatic activity.

Abstract: There is provided a plasma display. The plasma display includes a circuit having a first input that receives a first waveform, a second input that receives a second waveform, an output that provides a driving waveform for an electrode of a pixel in the plasma display, and a switching sub-circuit. The switching sub-circuit (i) routes the first waveform from the first input to the output during a first portion of a setup period to initialize the pixel for an addressing operation, and (ii) routes the second waveform from the second input to the output during a second portion of the setup period.

Abstract: The present invention applies a slope predictive control method to a Variable Temperature Control (VTC) system, measuring the slope of the discharge temperature as a function of flow regulation device position, and using this slope to predict the position of the flow regulation device needed to achieve the desired discharge temperature. The present invention also monitors the response of the VTC over time and utilizes a self-learning algorithm to predict the response time of the system in order to determine when further control adjustments need to be taken.
