Abstract: Testing apparatus which converts an electrical analog signal to digital form and then by the application of digital logic indicates and records departure from predetermined limits is disclosed. The apparatus also records in decimal form identification of the test composition specification limits and actual values at each test point over a selected testing range, over which range a parameter varies with time, and the value of the parameter is received in the form of an electrical analog signal.

Abstract: A sensitive method for detecting minute changes in apparently repetitive infrared signals in which infrared signals from repeated surface scans are processed by subtracting the signals representative of a scanning interval from signals representative of a subsequent scanning interval and differences resulting from a series of such subtractions are summed.
