Abstract: A sound monitoring system for collecting and processing an environmental noise level surrounding a work machine is disclosed. The sound monitoring system may include an acoustic sensor having a plurality of microphones arranged into a signal detection array to capture the environmental noise level and generate an acoustic output signal. Additionally, the sound monitoring system may include a controller communicably coupled to the acoustic sensor and programmed to perform a signal processing to identify a first portion and a second portion of the acoustic output signal. Furthermore, the controller may be programmed to generate a controller output signal based on the first and second portions of the output level. A speaker may be located on the work machine and communicably coupled to the controller such that the speaker receives and emits the controller output signal.

Abstract: A node monitoring system, including a plurality of nodes, each of the plurality of nodes registered and connected with a controller to simultaneously receive and return a short poll signal and a long poll signal; and a controller configured to: register an area as an operation zone having a boundary; simultaneously send and receive a short poll signal and a long poll signal to and from each of the plurality of nodes; command at least one of the plurality of nodes to power off in response to a failure to receive the short poll signal from the at least one of the plurality of nodes; alert others of the plurality of nodes that the at least one of the plurality of nodes is operating outside of a spatial boundary.

Abstract: A machine includes a rotational sensor configured to sense rotation of an upper frame of the machine relative to a lower frame of the machine. The machine also includes a three-dimensional position sensor spaced from an axis of rotation of the upper frame relative to the lower frame. The machine can also include a number of additional sensors including sensors to detect track movement, imaging sensors, ranging sensors, IMUs, linear displacement sensors and/or the like. A computing system receives the various inputs from the sensors and fuses the data to determine state information for the machine.
