DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] Referring to FIGS. 1-6, the various embodiments of the present disclosure are truly dependent upon the particular choice of the multitude of uses in which this system may be used by those specifically tailoring it to their needs.

[0021] In certain embodiments of the present disclosure, a modular identification system comprises a protective layer, a filter layer, and a reflective layer. The protective layer may be composed of polyvinyl chloride. The reflective layer may be composed of a retroreflective material. In these embodiments, the filter layer is ideally positioned between, and directly adjacent to, the protective layer and reflective layer. Each layer may be secured to any adjacent layers. In some embodiments, the protective layer may include an identification feature wherein said identification feature is defined by negative space formed in said protective layer which may itself be substantially opaque. For example, the word POLICE may be formed in said protective layer such that light may reflect off the reflective layer through the protective layer via the negative space corresponding to each of the letters. Of course, other words, symbols, or images could be similarly utilized as an identification feature.

[0022] Other embodiments of the present disclosure have at least one of a high-visibility mode, a covert mode, or a low light/back-lit mode. These embodiments allow for greater safety and identification customized for the environment and circumstances in which an embodiment is being used. As depicted in FIG. 1, these embodiments can further comprise a filter layer in addition to the layers described above. The filter layer may be composed of any material configured for selective, wavelength-specific filtration of light that can allow at least one range of wavelengths along the electromagnetic spectrum to pass, or otherwise filter through, the filter layer. In short, wavelength-specific selective filtration of light transference or reflection is provided by these embodiments of a modular PVC identification system of the present disclosure.

[0023] An embodiment including a high-visibility mode allows identification in low light conditions. The filter layer is configured to allow for high visibility and high levels of reflection in both normal light and when subjected to infrared light (night vision).

[0024] An embodiment including a covert mode allows identification under infrared light only. The filter layer in such an embodiment is configured to allow infrared light to pass through the filter layer such that the system is only semi-reflective in regular light.

[0025] An embodiment including a low light/back-lit mode includes the use of an interchangeable chemiluminescent backing layer, or a light emitting diode (LED) or other lighting method that is battery-powered. This backing layer is positioned adjacent, and secured, to the reflective layer on the side opposite the filter layer. Furthermore, the reflective layer is composed of a retroreflective material further configured to allow light emission from the backing layer to permeate the reflective layer, illuminating the desired area even with no external light source, as would be required for a reflective-only material. This ability to pass light through the reverse side of the retroreflective material, in combination with the addition of the LED or other self-contained light source, allows the product to retain luminescence, even in the absence of radiant light or an outside light source.

[0026] Another embodiment, due to the modular design, provides for existing identification technologies to be added as a peripheral component or rear layer, including but not limited to: global position satellite (GPS), radio frequency identification (RFID), or Bluetooth. Different future technologies are easily accommodating into this system design. In such embodiments, this rear layer would be positioned adjacent, and secured, to reflective layer on the side opposite the filter layer. In embodiments which include a backing layer, the rear layer may be positioned adjacent, and secured, to the backing layer on a side opposite the reflective layer.

[0027] A further embodiment provides for the use of different mountable attachment means for attaching, or otherwise securing (such as hooks and loop fasteners, embroidery, buttons, modular lightweight load-carrying equipment (MOLLE) systems, adhesives. or other functional equivalents), the modular identification system to various materials as best suited for the particular need.

[0028] Although the disclosure has been described with reference to specific embodiments, this description is not meant to be construed in a limited sense. Various modifications of the disclosed embodiments, as well as alternative embodiments of the disclosures will become apparent to persons skilled in the art upon the reference to the description of the disclosure. It is, therefore, contemplated that the appended claims will cover such modifications that fall within the scope of the disclosure.
