Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to indicator alarms and more particularly pertains to a new package-mounted sensor for alerting a user of a condition in which a package is being subjected. 
     2. Description of the Prior Art 
     The use of indicator alarms is known in the prior art. More specifically, indicator alarms 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 indicator alarms include U.S. Pat. No. 4,697,174; U.S. Pat. No. 4,792,796; U.S. Patent Des. 282,243; U.S. Pat. No. 4,057,029; U.S. Pat. No. 3,336,530; and U.S. Pat. No. 2,794,084 which are all incorporated herein by reference. 
     In these respects, the package-mounted sensor 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 alerting a user of a condition in which a package is being subjected. 
     SUMMARY OF THE INVENTION 
     In view of the foregoing disadvantages inherent in the known types of indicator alarms now present in the prior art, the present invention provides a new package-mounted sensor construction wherein the same can be utilized for alerting a user of a condition in which a package is being subjected. 
     The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new package-mounted sensor apparatus and method which has many of the advantages of the indicator alarms mentioned heretofore and many novel features that result in a new package-mounted sensor which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art indicator alarms, either alone or in any combination thereof. 
     To attain this, the present invention generally comprises a plurality of planar rectangular mounts each constructed from a flexible material such as paper or cardboard. An adhesive is situated on a rear face of the mount with a waxed paper backing situated over the adhesive. The waxed paper is adapted for being removed from the adhesive such that the mount may be secured to a package. Note FIG. 2. Each of the mounts has a portable power source and an alarm for transmitting an audible signal upon the receipt of power. A first one of the mounts includes a cross-shaped housing coupled to a front face of the mount. A conductive ball bearing is freely situated within the housing. As shown in FIG. 3A, a pair of spaced conductors pass through ends of three of four portions of the cross-shaped housing. Each of the conductors are connected to either the power source or alarm. As such, upon the ball bearing being situated within one of the three of the four portions, power is supplied from the power source to the alarm, thereby indicating that the package is tilted. A second one of said mounts includes a thermistor and a photoelectric cell each connected in parallel with respect to each other. The thermistor and photoelectric cell are further connected in series between the power source and alarm for supplying power from the power source to the alarm. This only occurs upon either the detection of light or heat. As such, an indication is given that the package is subjected to light and heat. A third and fourth of the mounts include a transmitter connected to the power source. In use, the transmitter is adapted for transmitting a signal via free space for a predetermined distance. A receiver is connected between the power source and alarm. The receiver is adapted for supplying power from the power source to the alarm upon the receipt of the signal via free space. This indicates that a package is with the predetermined distance from another package. Finally, a fifth mount includes a timepiece connected to the power source. In use, the shelf life expiration date of the package is set on a digital display screen, as shown in FIG. 7. The current date is displayed on a countdown display screen, as shown in FIG. 7. When the countdown date reaches the set shelf life expiration date, the alarm is activated. 
     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.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 7 thereof, a new package-mounted sensor embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     The present invention, designated as numeral 10, includes a plurality of planar rectangular mounts 12 each constructed from a flexible material such as paper, plastic, cardboard or the like. The mounts each preferably have a height of 3 inches, a width of 2 inches, and a thickness of about 1/8 of an inch. An adhesive 14 is situated on a rear face of the mount with a waxed paper backing situated over the adhesive. The waxed paper is adapted for being removed from the adhesive such that the mount may be secured to a package. Note FIG. 2. It should be noted that the package of the present invention refers to any container, cargo, case, drum, carton or the like. Each of the mounts has a portable power source 16 and a piezoelectric alarm 18, or buzzer, for transmitting an audible signal upon the receipt of power. The battery preferably takes the form of a silver oxide battery while the alarm is similar to those employed in the art of greeting cards. In the alternative, a visible indicator such as a LED or the like may be employed in lieu of or in combination with the buzzer. 
     A first one of the mounts includes a cross-shaped housing 20 coupled to a front face of the mount. A conductive ball bearing 24 is freely situated within the housing. As shown in FIG. 3A, a pair of spaced conductors 26 pass through ends of four of five portions of the cross-shaped housing. As shown in FIG. 3B, two of the portions of the housing are angled with respect to each other such that the housing has a Y-shaped configuration when viewed from the side. Each of the conductors is connected to either the power source or alarm. As such, upon the ball bearing being situated within one of the four portions, power is supplied from the power source to the alarm, thereby indicating that the package is tilted. It should be noted that any level indicator including, but not limited to, a mercury switch or the like may be used as long as the foregoing function is accomplished. 
     A second one of the mounts includes a thermistor 28 and a photoelectric cell 30 each connected in parallel with respect to each other. The thermistor and photoelectric cell are further connected in series between the power source and alarm for supplying power from the power source to the alarm. This only occurs upon either the detection of light or heat. As such, an indication is given that the package is subjected to light and heat. It should be noted that in the alternative, the thermistor may be used to detect low or high temperatures and actuate the alarm accordingly. 
     A third and fourth of the mounts are mounted on separate packages and each include a transmitter 32 connected to the power source. In use, the transmitter is adapted for continuously transmitting a signal via free space for a predetermined distance. A receiver 34 is connected between the power source and alarm. The receiver is adapted for supplying power from the power source to the alarm upon the receipt of the signal via free space. This indicates that the pair of packages are positioned within the predetermined distance. Finally, a fifth mount includes a timepiece connected to the power source. In use, the shelf life expiration date of the package is set on a digital display screen 38, as shown in FIG. 7. The current date is displayed on a countdown display screen 37, as shown in FIG. 7. When the countdown date reaches the set shelf life expiration date, the alarm is activated. While not specifically shown, it should be readily apparent in each of the forgoing circuits, the receiver, thermistor, photoelectric cell, timepiece and tilt switch are essentially switches for connecting the power source and alarm. 
     It should be noted that each of the foregoing mounts may be used either separately or in any desired combination to monitor certain conditions to which a package is subjected. The mounts may easily be situated on the associated package due to the use of the adhesive. As an option, a front cover may be situated on each mount with indicia warning against subjecting the package to the condition that is being monitored. By providing an alarm, a user may quickly take corrective action. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
