For a secondary radar system, however, two conditions must be satisfied : St > st and Sr > sr where st and sr are the minimum signals which can be detected by the transponder and responsor respectively.

In one sense the role is not new. The lay family member who attends the sick relative is part of a more ancient tradition than the physician or nurse. What is new in the concept of the responsor is contributed by the increasing complexity of modern therapy for chronic illness and the slow development of organized home care as a formal system for the application of such therapy in private homes.
