Abstract: The present invention relates generally to the field of immunological-based diagnostic assays. More particularly, the present invention contemplates a method for measuring cell-mediated immunoresponsiveness. The present invention further enables determination of the immunosuppressive effects of disease conditions, therapeutic agents and environmental contaminants. The assay of the present invention is also capable of integration into pathology architecture to provide a diagnostic reporting system and to facilitate point of care clinical management.

Abstract: A method and apparatus for testing rails for structural defects, the rails being associated with a railroad track include providing and using a first rail traveling vehicle for movement along a segment of rails followed by a second rail traveling vehicle for disposition behind the first rail traveling vehicle along the rails for testing with the first rail traveling vehicle having a first digital computer and a first analog computer and the second rail traveling vehicle having a second computer for display of data associated with the rails. A first modem assembly is provided in the first vehicle with a second modem assembly being provided in the second vehicle in communication with the first modem whereby data may be exchanged between the rail traveling vehicles. During testing, the first rail traveling vehicle transmits complete digital and analog rail structural and defect location information data to the second computer for analysis and action by the operators of the second vehicle.
