ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to speed limit detecting systems and more particularly pertains to a new speed limit detecting system for detecting and displaying to a driver the speed limit on the roadway the driver is travelling on.
2. Description of the Prior Art
The use of speed limit detecting systems is known in the prior art. More specifically, speed limit detecting systems heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. Nos. 5,484,992 (Inventors: Wiltz et al); 5,504,320 (Inventor: Adachi); 5,546,188 (Inventors: Wangler et al); 5,629,511 (Inventors: Iwaguchi et al); 5,550,363; and U.S. Pat. No. Design 384,651 (Inventors: Sandor et al), which are each incorporated herein by reference.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new speed limit detecting system. The inventive device includes bar coding indicia is displayed on a road sign. The bar coding indicia graphically indicates predetermined information of the speed limit displayed on the road sign. A scanner is provided in a user's vehicle for scanning the bar coding indicia to obtain the predetermined information of the bar coding indicia. The scanner has a visual display for visually displaying the predetermined information of the bar coding indicia to the user.
In these respects, the speed limit detecting system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of detecting and displaying to a driver the speed limit on the roadway the driver is travelling on.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of speed limit detecting systems now present in the prior art, the present invention provides a new speed limit detecting system construction wherein the same can be utilized for detecting and displaying to a driver the speed limit on the roadway the driver is travelling on.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new speed limit detecting system apparatus and method which has many of the advantages of the speed limit detecting systems mentioned heretofore and many novel features that result in a new speed limit detecting system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art speed limit detecting systems, either alone or in any combination thereof.
To attain this, the present invention generally comprises bar coding indicia is displayed on a road sign. The bar coding indicia graphically indicates predetermined information of the speed limit displayed on the road sign. A scanner is provided in a user's vehicle for scanning the bar coding indicia to obtain the predetermined information of the bar coding indicia. The scanner has a visual display for visually displaying the predetermined information of the bar coding indicia to the user.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structure, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new speed limit detecting system apparatus and method which has many of the advantages of the speed limit detecting systems mentioned heretofore and many novel features that result in a new speed limit detecting system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art speed limit detecting systems, either alone or in any combination thereof.
It is another object of the present invention to provide a new speed limit detecting system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new speed limit detecting system which is of a durable and reliable construction.
An even further object of the present invention is to provide a new speed limit detecting system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such speed limit detecting system economically available to the buying public.
Still yet another object of the present invention is to provide a new speed limit detecting system which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new speed limit detecting system for detecting and displaying to a driver the new speed limit on the roadway the driver is travelling on.
Yet another object of the present invention is to provide a new speed limit detecting system which includes bar coding indicia is displayed on a road sign. The bar coding indicia graphically indicates predetermined information of the speed limit displayed on the road sign. A scanner is provided in a user's vehicle for scanning the bar coding indicia to obtain the predetermined information of the bar coding indicia. The scanner has a visual display for visually displaying the predetermined information of the bar coding indicia to the user.
Still yet another object of the present invention is to provide a new speed limit detecting system that helps drivers become aware about speed limit changes on a roadway to help a driver avoid speeding on roadways where the speed limit is reduced and because the driver did not see a speed limit sign for the roadway.
Even still another object of the present invention is to provide a new speed limit detecting system that may be used in pre-existing vehicles and also may be installed as an integral factory feature of the vehicle.
These together with other objects of the invention, along with the various
