  • Diagnostic vibration data collector and analyzer
    Patent number: 6484109
    Abstract: A diagnostic vibration data collector and analyzer which incorporates an expert system within a portable computer such as a laptop or notebook type computer. The expert system analyzes vibration data acquired via a sensor coupled to the collector/analyzer in order to diagnose a condition of a machine under test. Several collector/analyzers may form part of a system in which peer to peer replication of data and information is performed so as to obviate the need for a central host computer and/or data base. Such system may include one or more stationary computers also serving as peers.
