Abstract: A battery powered device includes a battery and a motor controller that is coupled to the battery. A motor is operably coupled to the motor controller. The motor controller is configured to detect an amount of available power from the battery and engage the motor based on the amount of available power.

Abstract: A wireless field device for use in monitoring acoustic noise includes an acoustic sensor configured to sense acoustic noise. Processing circuitry coupled to the acoustic sensor is configured to identify a hazardous noise condition based upon the sensed acoustic noise and a personnel noise exposure standard. Output circuitry provides a warning output in response to an identified noise condition. A system is also provided which uses one or more acoustic sensors implemented in wireless field mounted monitors.
