     DETAILED DESCRIPTION 
       [0012]      FIG. 1  is an illustration of a shrink wrap film  10  for application to a fire hydrant  12  according to the teachings of the present disclosure. Fire hydrants are ubiquitous fixtures on urban streets that allow firefighters to tap into a water supply for fire protection. Fire hydrants are typically made from a metal such as grey or ductile iron. The exterior of fire hydrants is usually painted a bright red color with conventional paint. The current invention contemplates applying a shrink wrap film  10  bearing advertising content to fire hydrants  12 , possibly as a revenue source for city governments or other entities. 
         [0013]    The shrink wrap film  10  may be made from a polymer plastic of various materials suitable for tentering, printing, and subsequent shrinking, including but not limited to copolyesters, polyvinylchloride (PVC), polyvinylidene fluoride (PVDF), polylactide (PLA), and thermoplastic styrene-butadiene copolymers (Styrolux). The film  10  preferably is made from a thermoplastic that can be heated and extruded into a thin film. The film  10  can be a single flat sheet with incorporated tape to join the ends or edges, or it may be a film cylinder that can be easily slid over the hydrant to be formed and shrunken by the application of heat. Because of the irregular shape of the fire hydrant, the film  10  may be cut, contoured, and/or shaped in advance and then installed onto the fire hydrant  12 . 
         [0014]    At a microscopic level, the long, thin polymer molecules are lined up in rows. When the heat or pressure is applied, the molecules vibrate against one another and begin to tangle and twist together. This action decreases the volume of the shrink-wrap film, causing the film to tightly wrap and cling to the fire hydrant. 
         [0015]    The shrink wrap film  10  may be constructed using a multi-layer construction, where each layer may be a transparent, translucent, or opaque material. One or more layers of the film may include visual patterns, static images, logos, printed text, graphical text, seasonal decorations, or optical devices such as holographic images, holographic textures, optical lenses, and the like, separately or in combination thereof. The shrink wrap film  10  may further incorporate tactile textures and patterns. Further, one or more layers of the film may incorporate optical reflective devices that is arranged to bounce incident light back out for esthetic and/or safety purposes. The film  10  will also protect the fire hydrant from the elements, helping to reduce the frequency that the fire hydrant needs to be repainted. 
         [0016]      FIG. 2  is another illustration of a shrink wrap film  20  applied to a fire hydrant  12  configured to elicit an audio response from a smartphone  22  according to the teachings of the present disclosure. The shrink wrap film  20  may further incorporate passive electronic devices that are configured to cause a smartphone  22  (or another computing device capable of wireless communications) carried by a pedestrian that comes within a predetermined range of the fire hydrant  12  to undertake certain action. For example, the smartphone  22  may automatically access an Internet location to automatically download advertising content, such as an audio message or song, that is automatically played over the smartphone&#39;s speakers. As another example shown in  FIG. 3 , the smartphone  22  may automatically access an Internet location to automatically download another form of advertising content, such as a shopping coupon for a manufacturing or retail entity, that is automatically displayed on the smartphone&#39;s screen. Yet another example, shown in  FIG. 4 , contemplates the smartphone  22  detecting the existence of the fire hydrant  12  and causes the shrink wrap film  40  that includes circuitry configured to play or display advertising content, such as a commercial jingle, a popular song, or audio message. The shrink wrap film  40  may also incorporate visual elements  42  such as lighting elements of one or more colors and shapes, a display screen, spotlights, beacons, etc. to provide information, attract attention, and/or provide scene lighting. 
         [0017]    It is further contemplated herein that the shrink wrap film may incorporate circuitry that is configured to broadcast or transmit fire hydrant location and status (e.g., water in the hydrant when the hydrant is off). In another embodiment, the shrink wrap film may incorporate a traffic signal preemption receiver that is receptive to the traffic preemption activation signal (e.g., acoustic, line-of-sight, global positioning system (GPS), and localized FHSS (Frequency Hopping Spread Spectrum) radio frequency (RF) signals) emitted by an emergency vehicle and fire trucks. Upon detecting a traffic preemption activation signal emitted by a fire truck  44  ( FIG. 5 ), the circuitry in the shrink wrap film may emit a response RF signal or beacon (or another form of visual cue) that aids the firefighting personnel in locating the fire hydrant quickly and efficiently. The RF signal or beacon may cause an app on the smartphone to display a map and the location of nearby fire hydrants. The shrink wrap film may additionally activate a beacon or scene lighting also incorporated in the shrink wrap film upon detection of emergency vehicles  44  in close proximity. 
         [0018]      FIG. 5  is a simplified block diagram of an exemplary embodiment of a circuitry  50  incorporated into the shrink wrap film  10  applied to a fire hydrant according to the teachings of the present disclosure. The circuitry  50  includes a processor  50  configured to execute a plurality of computer instructions and access stored data in one or more memory devices  52  (RAM, ROM, EEPROM, etc.). The circuitry  50  further includes a transceiver  54  and antenna  56  for receiving and transmitting data with the smartphone and/or emergency vehicles. Any suitable short range wireless communication technology may be used, such as ANT+, IEEE 802.15.4, IEEE 802.22, ISA 100a, RFID, Bluetooth, Near Field Communications (NFC), Infrared, UWB, WirelessHD, WirelessUSB, ZigBee, WiFi, WiFi Direct, FHSS (Frequency Hopping Spread Spectrum) short-range radio signal, etc. The circuitry  50  further includes audio/visual interface devices  58 , such as lighting elements, display elements, display screens, speakers, etc. 
         [0019]    The circuitry  50  may include a power source (e.g., solar) or function like a passive RFID circuit that draws energy from the received RF signal emitted from the smartphone and/or emergency vehicle. 
         [0020]    The features of the present invention which are believed to be novel are set forth below with particularity in the appended claims. However, modifications, variations, and changes to the exemplary embodiments described above will be apparent to those skilled in the art, and the shrink wrapped advertising on fire hydrants described herein thus encompasses such modifications, variations, and changes and are not limited to the specific embodiments described herein.
