1. A code detecting system associated with moving objects, the system comprising:
at least one light source that is configured to provide light; at least one light sensor that is configured to detect light respectively provided by the at least one light source, wherein the light provided by the at least one light source reflects from a machine readable code supported by a surface of a moving object; at least one processor that is configured as a function of executing instructions in non-transitory processor readable media; and a display configured to display information from the at least one processor, wherein light from the at least one light source reflects from at least a first portion of the machine readable code as the object moves, and is detected by the at least one light sensor, further wherein light from the at least one light source reflects from at least a second portion of the machine readable code as the object moves, and is detected by the at least one light sensor, and further wherein the at least one processor is configured to:
determine, as a function of the machine readable code, information representing the moving object;identify a first time when the at least one sensor detects the light reflecting from the first portion of the machine readable code;identify a second time when the at least one sensor detects the light reflecting from the second portion of the machine readable code; anddetermine a speed of the moving object, as a function of the information representing the object, the first time and the second time, further wherein, information representing at least the speed of the object is generated by the at least one processor and displayed by the display. |
