Abstract
An improvement in a system that includes a group of field units (10, 10A) that each identifies unknown microscopic particles by use of a computer that compares an unknown particle interrogation pattern to the interrogation patterns of a set of known species of particles, which facilitates upgrading of the group of field units. Each field unit is connected by a communication link (84) to a central station (80). The central station can send interrogation patterns of a new species of particle to the field unit computers, which store them in a known-species-particle memory (34) that holds patterns of previously known species of particles. The field unit stores the patterns of unidentified particles in a memory (90) and notifies the central station when it has detected an invasion of a new species.
