The proximity warning system includes an operator interface including first group of visual indicators including a low level indicator and a high level indicator, a second group of visual indicators including a low level indicator and a high level indicator, an audio indicator operable at a first volume and at a second volume, and operator inputs configured to receive selections from an operator. The proximity warning system is configured to provide both low level and high level alarms to an operator when an obstacle approaches or enters a safe zone, and when the machine approaches and enters a hazard zone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Worksite proximity warning and collision avoidance system","description":"A proximity warning and collision avoidance for a machine on a worksite operating near obstacles is disclosed.
