  • Method for describing measured results
    Patent number: 5590055
    Abstract: A method for generically describing measured results which includes defining a class of entities to be measured, and a set of criteria which distinguish entities within the class of entities to be measured. A computer display format is dynamically configured based on the set of criteria. The set of criteria is displayed on the computer display according to the computer display format. The values related to an individual entity are interactively specified. The set of measurements related to class of entities to be measured is displayed on the computer display screen and are associated with the set of criteria.
