Abstract: A numeric diagnostic electrocardiometer includes an A/D converter for converting an EKG signal at each of the conventional electrodes employed in EKG analysis into numbers which are stored in an assigned memory as time and amplitude signals. The waveform is divided into time segments within which the basic waveshape is known. A programmed logic array stores abnormalities within a range for each segment of the EKG waveforms. The stored samples are read into the programmed logic array and deviation of the waveform beyond that programmed produces a numeric output. The instrument may directly translate any deviation output into a readout code referenced to a suitable manual for each combination of time and sampled data. The individually stored samples may also be read out from the memory. The instrument also includes a heart rate and heart arrythmia detection units for initial analysis of the heart.

Abstract: A passive thermographic analytical apparatus for determining the presence of cancer includes a left and right breast scanner array, each of which includes a matrix of infra-red energy sensors and reflectors mounted in a close spaced array for producing a pattern of temperature measurements. The arrays are mounted within an adjustable support to permit spatial positioning and alignment of the arrays. Each sensor produces an analog voltage proportional to the body temperature. The sensor output voltages are sequentially read and converted into appropriate digital form for storage in a RAM memory of a microprocessor, which includes a pattern recognition program to directly create an automated diagnosis of the radiation pattern from which the normality or abnormality of the breasts can be diagnosed. The various parameters are reduced to a multiple digit number which is displayed. The number is encoded to a particular condition.
