Abstract: Systems and methods for establishing a rooted, directed network that acquires and passes sensor data. In one embodiment, the network includes a controller, a logging device, one or more routers, and one or more end nodes. Each network device includes at most one parent node and a unique network message path. The network is established in an ad hoc manner without a need for routing tables. Other embodiments of the invention provide a rooted, directed network for monitoring industrial equipment such, as pumps, fans, rolls, gearboxes, motors, and bearings.

Abstract: A monitoring and controlling system for monitoring and controlling various operating characteristics of machine components. The monitoring and controlling system includes a primary transceiver, with sensors and control devices, mounted integrally with the monitored component. The primary transceiver communicates with a secondary transceiver and receives its electrical power from the secondary transceiver without use of interconnecting communication or power cables. The integrated mounting of the primary transceiver and sensors within the monitored component without the use of interconnecting cables allows for replacement of the monitored component in harsh operating environments without the risk of damage to interconnecting electrical connectors and cables. The operating data detected by the sensor for the monitored component is communicated by the primary transceiver and the secondary transceiver to a monitoring network which analyzes the data to determine the need for maintenance of the monitored component.

Abstract: A tapered roller bearing has at least one groove in its fixed race, with that groove being located behind and presented away from the raceway for the race. The groove, which creates an unsupported beam within the race, contains a strain sensor which is oriented to detect strains in the circumferential direction. The presence of a loaded roller over the beam deflects the beam and causes the sensor to produce a signal, with the magnitude of the signal reflecting the magnitude of the load transmitted by the roller. By locating one sensor where the greatest radial load is transmitted and two sensors 30° to 70° symmetrically on each side of that one sensor, one can measure both radial and axial loads in the bearing. By locating two sensors in a single groove, axially aligned, but also axially offset, one can detect misalignment of the raceways along which the rollers roll and also skewing of the rollers.
