Description:
TECHNICAL FIELD 
     The invention relates to a bracket used for mounting a tag that is used to identify the location of mobile objects in real time. More particularly, the invention relates to a bracket for mounting a removable tag for installation on trucks, trailers, intermodal containers, railcars and the like in the field of yard management. 
     DESCRIPTION OF THE BACKGROUND ART 
     There are currently millions of trucks, semi-trailers, railcars, and intermodal containers in use in the United States. For logistics and efficiency it is desirable to know the position in real time of each piece of equipment. In order to do this radio frequency identification (RFID) tags are currently being used. 
     RFID tags are used to associate an object with an identification code or other information. RFID devices generally have a combination of antennas and analog and/or digital electronics, which may include for example communications electronics, data memory, and control logic. 
     RFID tags are used in position tracking systems to identify the location of mobile objects in real-time and are used in a wide variety of applications, including transportation, logistics management, healthcare, and security. 
     For objects that are moved with a vehicle, such as inter-modal shipping containers or trailers, being able to locate the position of the objects in real-time can help improve the efficiency of supply-chain and inventory management while reducing the loss in productivity of assets. The use of RFID tags eliminates the need for staff members to search for trailers as well as enables carriers and shippers to access data regarding shipments&#39; locations via the Internet. This is currently done by permanently securing RFID tags directly to objects by means such as screws, bolts rivets and welding. The RFID tags are then read by electronic readers, such as readers installed on gates at the entrance of a yard. The information gathered by the reader is then sent to a yard management system. 
     Permanent tags have the disadvantages of being labor intensive to install, labor intensive to remove and replace, and requiring a different tag for every object to be tagged. Accordingly, it would be desirable to provide a tag that is not permanent and could be installed, removed and replaced with little labor as well as provide a tag that can be used by multiple objects at different times. Further, it would be desirable to provide a mounting apparatus to attach to the object that provides a surface to attach a nonpermanent tag such that the tag is located in a position that is secure, accessible to a user, and allows the tag to be scanned. 
     SUMMARY OF THE INVENTION 
     An apparatus for temporarily attaching an RFID tag to a mobile object includes a bracket comprising a first arm comprising an object mounting surface, and a second arm, adjoining the first arm, comprising a tag mounting surface. The first arm further comprises an attachment mechanism used to attach the bracket to a support surface.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  shows an embodiment of an L-shaped bracket  1 . In the embodiment shown in  FIG. 1 , a first arm consists of a first substantially planar member  2  adjoining a second arm consisting of a second substantially planar member  3 . The first arm comprises an object mounting surface  4  which is in contact with a support surface of a trailer, truck, intermodal container, railcar or the like when the bracket is mounted to the support surface. In embodiments, the first arm and object mounting surface are generally rectangular in shape, however those skilled in the art will appreciate that they may be of any shape designed to fit into specific spaces. 
     In an embodiment, the first arm is mounted flush with a support surface. In the case of a flat support surface, the object mounting surface is preferably flat, and in the case of a curved support surface the object mounting surface is preferably curved to match the curve of the surface of the object. In some embodiments, the first arm and object mounting surface are constructed to be rigid and in other embodiments, they are constructed to be slightly deformable in order to be flush when attached to support surfaces that are imperfect or that deflect or change shape during use. Further, in embodiments, the object mounting surface comprises a rubberlike coating or layer that increases friction and flushness between the bracket and the support surface to which it is mounted. Further, those skilled in the art will appreciate that the first arm and object mounting surface can be formed to match the shape and surface features of any surface the bracket is to be mounted. 
     The first arm comprises an attachment mechanism for attaching the bracket to a support surface. In embodiments, the attachment mechanism comprises magnets, electromagnets, adhesives, suction, or mechanical fasteners such as Velcro®, a slot and groove combination, or a clip and flange combination, or any combination thereof. 
     Trucks, semi-trailers, intermodal containers, railcars, and other equipment commonly used in the shipping, transportation, and warehouse industries contain metal surfaces to which a magnet can be attached using magnetic forces. Therefore, in an embodiment, the attachment mechanism is preferably one or more magnets. As shown in  FIG. 1 , an embodiment includes two magnets  5  attached to the first substantially planar member  2 , which allow the bracket to attach to a metal support surface via magnetic forces. As shown in  FIG. 1  in an embodiment, the magnets are attached to a top surface  6  of the first arm with rivets  7 . In other embodiments, the magnets are encapsulated within the first arm, are attached to the first arm inside of a recess, or are attached to a bottom surface of the first arm. In embodiments, the magnets are round, square, or any other geometric shape. In embodiments, the magnets are attached to the first arm by adhesive, press fit, rivets, screws, bolts, or any other mechanical fastening means. In embodiments, the holding ability of the attachment mechanism exceeds any challenges posed by air resistance, snow, rain, and vibration. Further, in an embodiment, the bracket is mountable on a wet surface, or a surface covered with one mm of either ice, mud, or both. 
     The bracket further comprises a connection adjoining the first arm and second arm. In the embodiment shown in  FIG. 1 , the connection adjoining the arms comprises a bend  8 . In some embodiments, the first arm, second arm, and connection adjoining the arms are integrally formed. In some embodiments, the first arm, connection, and second arm are not integrally formed. In embodiments, the angle between the first and second arms is right, obtuse, or acute. In an embodiment, the first arm and second arm are connected by a locking hinge. In this embodiment, the bracket is selectively rotatable between a closed and open position.
