  • Patent number: 9367042
    Abstract: An alert system in equipment used in an asphalt paving environment, such as a compactor, signals an operator when the equipment is stopped on hot asphalt, potentially over-compacting the area where the equipment is located. The alert system includes a surface temperature sensor so that the alert is only activated when there is a risk of over-compaction because the asphalt is still above a threshold temperature. The alert system may also include a timer so that the operator is not signaled during routine stopping associated with changing direction during compacting operations.
    Type: Grant

  • Publication number: 20150092393
    Abstract: A lighting system for a work machine is provided. The lighting system includes a plurality of step lights disposed on a stairway of the work machine. The lighting system further includes a lighting power source configured to provide power to the plurality of step lights for lighting, independently of an operational state of the work machine. The lighting system also includes a radio frequency identification reader configured to read a radio frequency identification tag associated with an operator. The lighting system further includes a lighting control module configured to receive a signal based on the reading of the radio frequency identification tag. The lighting control module further detects if the operator is proximate to the work machine. The lighting control module further triggers an activation of the plurality of step lights based on the detection of the operator proximate to the work machine.
