Abstract
An accident prevention system for a doorway of a loading dock is provided. The system includes a first sensor configured to detect an object in a first predetermined location and having a height that is greater than a predetermined height. A second sensor is configured to activate responsive to detection by the first sensor of an object having a height that is greater than the predetermined height. The second sensor is also configured to detect an object in a second predetermined location after activation of the second sensor. An alert system is configured to generate a humanly-perceivable alert responsive to detection of the object in the second predetermined location after the activation of the second sensor.
Claims11
An accident prevention system for a doorway of a loading dock, the system comprising:
- a first sensor configured to detect an object in a first predetermined location and having a height that is greater than a predetermined height;
- a second sensor configured to activate responsive to detection by the first sensor of an object having a height that is greater than the predetermined height, the second sensor also being configured to detect an object in a second predetermined location after activation of the second sensor;
- and
- an alert system configured to generate a humanly-perceivable alert responsive to detection of the object in the second predetermined location after the activation of the second sensor.
A method of generating an alert indicating that a height of an object approaching a loading dock doorway exceeds a predetermined height, the method comprising steps of:
- determining, when the object is in a first predetermined location, that the height of the object exceeds the predetermined height;
- determining, after the determination that the height of the object exceeds the predetermined height, that an object is in a second predetermined location;
- and
- generating a humanly-perceivable alert responsive to the determination that an object is in the second predetermined location.
