Abstract: A sensor sampling system comprises a field unit to receive at least one analysis parameter from a base station and a signal representing a machine parameter monitored by a machine sensor. The field unit analyzes the signal based on the at least one machine parameter to generate a representation of the machine parameter, and wirelessly transmits the representation of the machine parameter for reception by the base station.

Abstract: A vibration-sensing field unit includes a base with at least one accelerometer, and a body mounted to the base. The base is composed essentially of a first material, while the body is composed essentially of a second material that is more flexible than the first material to reduce a vibration at the accelerometer caused by a mass supported by the body. In another embodiment, a vibration-sensing field unit includes at least one accelerometer and at least one ultrasonic transducer.

Abstract: A sensor sampling system comprises a base station and a field unit. The field unit receives a quasi-periodic signal representing machine parameters monitored by a machine sensor, and samples a first portion of the quasi-periodic signal to generate a first reference waveform. The field unit subsequently samples a second portion of the quasi-periodic signal to generate a first sample waveform. Finally, the field unit generates a first delta data set representing a difference between the first reference waveform and the first sample waveform and wirelessly transmits a representation of the first delta data set for reception by the base station.

Abstract: A facility modeling system renders graphical representations of machines and their environment in a facility model to facilitate monitoring of machine parameters and health. A sensor control module communicates with a plurality of sensors detecting machine parameter data for machines housed in a facility. The machine parameters may include any information that may directly or indirectly indicate the status of a machine or a part of a machine. The information collected from the sensors is incorporated into the facility model (a graphical rendering of the facility) which may provide any of a variety of multi-dimensional views of the facility. A GUI allows a user to navigate through the facility model to identify and monitor the status of the sensors. The sensor status may be indicated by an icon, callout, change in a display characteristic of a facility, machine, part, space, or item, a combination of these, and the like.
