Abstract: An electrically alterable, non-volatile multi-bit memory cell has K.sup.n predetermined memory states (K.sup.n >2), where K is a base of a predetermined number system and n is a number of bits stored per cell. Programming of the cell is verified by selecting a reference signal corresponding to the information to be stored and comparing a signal of the cell with the selected reference signal.

Abstract: One or more lines of a communication terminal are monitored to determine blocked calls by detecting times of incoming calls. A signal corresponding to the pattern of incoming calls is generated from the detected times. After detection of the starting time of an all lines are busy state, an estimate of blocked calls is formed from the incoming call pattern signal and the detected start of the all lines are busy state.

Abstract: This invention relates to novel recombinant antigenic proteins of avian coccidiosis, and fragments thereof containing antigenic determinants, and to the genes that encode the antigenic peptides. This invention also relates to vaccines made using the novel antigenic proteins of avian coccidiosis and to methods of immunizing chickens against avian coccidia.

Abstract: In a system for compressing video data, temporally adaptive motion interpolation based upon temporal characteristics of human vision is used for establishing threshold levels relative to the degree of motion as a whole (global motion) between frames. The global motion between successive frames in a group of pictures (GOP) is measured to determine if the motion is less or greater than the established threshold levels for determining the designation of I, P, and B frames, spacing between I and P reference frames, and the number of bits used for each frame, and B frames therebetween.
