Abstract:
1. A method for generating an alert for a possible collision between objects and a swinging barrier, comprising: providing a plurality of sensing devices, a control unit, and a plurality of indicator devices at predetermined areas proximal to said swinging barrier, wherein said sensing devices and said control unit electronically communicate with said indicator devices; configuring said sensing devices to establish sensing zones proximal to said swinging barrier; detecting presence of one or more of stationary objects, approaching objects, and receding objects in said established sensing zones proximal to said swinging barrier by said sensing devices; tracking and differentiating said presence of said stationary objects, approaching movements of said approaching objects, and receding movements of said receding objects in said established sensing zones proximal to said swinging barrier by said control unit in electronic communication with said sensing devices; generating an alert signal by said control unit on detection of one or more of said presence of said stationary objects, said approaching movements of said approaching objects, and said receding movements of said receding objects in said established sensing zones proximal to said swinging barrier, wherein said control unit transmits said alert signal to said indicator devices; and selectively indicating said possible collision between said objects and said swinging barrier by said indicator devices based on said presence of said stationary objects, said approaching movements of said approaching objects, and said receding movements of said receding objects in said established sensing zones, on receiving said alert signal from said control unit.
