Abstract
A safety system includes an apparatus-mounted projector capable of projecting a warning image onto a designated danger zone about a dangerous implement of the apparatus. The projector is in signal communication with an electronic control module configured to control the warning image depending on a measured or received operational state of the apparatus implement. The projected warning image can include static, dynamic, or static and dynamic image elements depending on the measured or received operational state of the implement.
Claims20
A system for projecting a warning image onto a ground surface within a selected danger zone of a vehicle, comprising:
- an optical projection system configured to controllably project a warning image onto said ground surface that substantially encompasses said selected danger zone;
- and
- an electronic control module configured to control said optical projection system according to an operational state of a machine implement of said vehicle that creates a substantially invisible hazard when operating within, or proximal to said defined danger zone.
A method for reducing the likelihood of injury near a mechanical implement of a vehicle, comprising:
- defining an injurious danger area on a ground surface proximal to said mechanical implement of said vehicle, wherein said mechanical implement creates a substantially invisible hazard when operating;
- providing an optical projection system configured to project a warning image onto said ground surface substantially encompassing or proximal to said injurious danger area;
- providing an electronic control module in signal communication with said optical projection system that is configured to control said projected warning image;
- and
- configuring said electronic control module to cause said warning image to be projected on said ground surface according to an operational state of said mechanical implement.
A safety system for reducing the likelihood of injury near an aircraft engine or propeller, comprising:
- an optical projection system configured to be mounted to an aircraft frame and project a warning image substantially encapsulating a selected injurious danger area on a ground surface proximal to said aircraft engine or said propeller;
- and
- an electronic control module in signal communication with said optical projection system that is configured to control both projection of, and projected graphical elements of said warning image;
- wherein said electronic control module is further configured to project a warning image onto said ground surface according to a measured operational state of said engine or said propeller;
- wherein for a first measured operational state said warning image comprises static image elements and for a second, different operational state said warning image comprises animated image elements.
