Abstract: Cyclotomic polynomials are used to construct subgroups of multiplicative groups of finite fields that allow very efficient implementation of discrete logarithm based public key cryptosystems, including public key encryption schemes and digital signature schemes. A field is represented with an optimal normal basis, and a generator of a subgroup of the multiplicative group of the field is used to form a public key.

Abstract: The siphoning device, with measuring indicators, is used for liquid-liquid separation. The body member has an outlet with an open tip; the outlet can have a peripheral rim with notches proximate the open tip. A two-way liquid valve contoured to approximate the contour of the interior of the outlet, controls liquid flow out of the body and permits flow into the body. A stem portion affixed to the liquid valve extends through and beyond the open tip of the outlet. Pressure on the stem places the valve in an open position and permits liquid to be discharged. An air pump interacts with the body to expel air and draw in the liquids. Generally the air pump is a flexible bulb with a one-way air valve to restrict air flow into the hollow body while permitting air flow out. The hollow body can be in two parts which are removably connected to one another. The travel of the liquid valve within the hollow body is limited by stops.

Abstract: To correct non-linearity and noise in the conversion of a pulse code modulated signal (PCM) into a uniform pulse width modulated signal (UPWM), a model is made of the known non-linearity in the conversion by dividing a plurality of non-linearity components in the model, where the polynomial components are separately weighed with filter coefficients. The model is used as a basis for the construction of a filter of the Hammerstein type whose non-linear parts consist of a division of the PCM signal into a plurality of powers, and whose linear parts are approximated by means of the model made. With the circuit of the invention it is now possible to construct a purely digital amplifier which has a great efficiency, low weight, etc.
