  • Patent number: 10739187
    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.
    Type: Grant

  • Patent number: 10305403
    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.

  • Patent number: 6176779
    Abstract: A compactor for a cotton harvester basket includes an automatic compactor auger control system having a pair of optical sensors mounted in the basket utilizing light blockage to detect a preselected level of cotton in the basket. When the preselected cotton level is reached, a full basket signal is sent to a microprocessor based controller which activates the compactor augers if certain interlock conditions are satisfied. The microprocessor control maintains the augers in operation until the cotton is compacted below the preselected level so the light signal is no longer blocked. An adjustable timer assures compactor operation for a minimum period of time to prevent short, intermittent periods of operation when the basket is filling and permits timing adjustments to accommodate varying cotton conditions.
