Abstract: An improved stethoscope design with an extended detection range for sounds above and below the range of human hearing and artificial intelligence connection to other clinical data for analysis.

Abstract: An improved stethoscope design with an extended detection range for sounds above and below the range of human hearing and artificial intelligence connection to other clinical data for analysis, wherein the stethoscope assesses spatial distribution of bodily sounds using a sensor array as well as amplifies the volume of bodily sounds and provides for recording, receiving and processing same.

Abstract: A monomer, polymers containing the monomer, and the use of the polymer in oilfield flooding is disclosed. The subject monomer is represented by the general formula: ##STR1## wherein: n is an integer from 0 to about 4; m is an integer from 0 to about 6; a is an integer equal to at least 1 except where m is equal to 0, a must equal 0 and where m is equal to 1, a must equal 0 or 1; p is an integer from 2 to about 10; b is an integer equal to at least 1 and is of sufficient magnitude that the ratio b/p is at least 0.2; and q is an integer from 0 to 2. The number of hydroxy groups in the monomer is believed to be critical, and therefore the sum of (a+b) divided by the sum (m+p) should be at least 0.2. The moieties linked to the acrylic nitrogen can be joined to provide a ringed structure.
