DETAILED DESCRIPTION

(8) The following description of the variations is merely illustrative in nature and is in no way intended to limit the scope of the disclosure, its application, or uses. The description is presented herein solely for the purpose of illustrating the various embodiments of the disclosure and should not be construed as a limitation to the scope and applicability of the disclosure. In the summary of the disclosure and this detailed description, each numerical value should be read once as modified by the term about (unless already expressly so modified), and then read again as not so modified unless otherwise indicated in context. Also, in the summary of the disclosure and this detailed description, it should be understood that a value range listed or described as being useful, suitable, or the like, is intended that any and every value within the range, including the end points, is to be considered as having been stated. For example, a range of from 1 to 10 is to be read as indicating each and every possible number along the continuum between about 1 and about 10. Thus, even if specific data points within the range, or even no data points within the range, are explicitly identified or refer to only a few specific, it is to be understood that inventors appreciate and understand that any and all data points within the range are to be considered to have been specified, and that inventors had possession of the entire range and all points within the range.

(9) Unless expressly stated to the contrary, or refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by anyone of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

(10) In addition, use of the a or an are employed to describe elements and components of the embodiments herein. This is done merely for convenience and to give a general sense of concepts according to the disclosure. This description should be read to include one or at least one and the singular also includes the plural unless otherwise stated.

(11) The terminology and phraseology used herein is for descriptive purposes and should not be construed as limiting in scope. Language such as including, comprising, having, containing, or involving, and variations thereof, is intended to be broad and encompass the subject matter listed thereafter, equivalents, and additional subject matter not recited.

(12) Also, as used herein any references to one embodiment or an embodiment means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase in one embodiment in various places in the specification are not necessarily referring to the same embodiment.

(13) In accordance with some aspects of the disclosure, a draper belt design includes sensors embedded within the draper belt itself. The sensors sufficiently communicate with a belt protection controller, or any other suitable device, to relay useful information regarding key measurable properties, such as, but not limited to belt speed, belt temperature, belt stress, belt alignment, and the like, or other information such the belt's manufacturing date code or serial information. The useful information may be relayed to and received by an operator, a control system(s), management, or any suitable combination thereof, to then be notified about the condition of the draper belt, as well as potentially damaging condition of the draper belt. In some aspects, the information is relayed in real time so the property, or properties, of the belt is ascertainable in situ. In some other aspects, the information may be accumulated in a package, and later relayed as appropriate.

(14) In those cases where the draper belt properties are measured and the resultant information relayed in real time, the recipient of the information may be enabled to modify the operating scenario to avoid or otherwise correct for potential draper belt mistracking. Where the draper belt is actually mistracked, the system provides an immediate emergency notification to the recipient to then, in turn, stop and correct the mistracked draper belt situation.

(15) In some embodiments, the resultant information transferred is used to proactively adjust the equipment to improve the performance of the belt, or even in some cases to avoid a catastrophic event.

(16) In some aspects, the sensors provide details to a control unit, and software integrated therewith is used to provide the draper belt condition to a general user interface or monitor, based upon the information received. The general user interface or monitor may be viewed, in some cases, by a crop harvesting equipment operator, and appropriate action may be taken by the operator to avoid damaging the draper belt.

(17) Now referring to FIGS. 1 through 5, a crop harvesting header H is depicted and includes a header frame F, with draper arm assemblies DA and end tilt arm assemblies E pivotally secured to the frame F. The assemblies DA and E support cutterbar assembly C. The cutterbar assembly C includes a flexible cutterbar B and skids S carried on the forward ends of the assemblies DA and E. The header H also broadly includes a draper assembly A with side draper belts SD and center draper belt CD. The header H includes a lower belt support assembly L. Additional details of some of the other components of the header are disclosed in U.S. Pat. No. 7,836,671, issued Nov. 23, 2010, entitled FLEXIBLE DRAPER AND CUTTER BAR WITH TILT ARM FOR CUTTERBAR DRIVE, which is hereby incorporated in its entirety by reference herein.

(18) FIG. 6 depicts a portion of draper belt embodiment, such as those which could be used in crop harvesting header H as side draper belts SD and center draper belt CD in a perspective sectional view, in accordance with some embodiments of the disclosure. As described above, the draper belt generally includes one or more sensors embedded within the draper belt itself, which sufficiently relay useful information regarding key measurable properties, such as, but not limited to belt speed, belt temperature, belt stress, belt alignment, and the like, or other information about the belt. In an aspect of the disclosure, draper belt cleat 1 may include an embedded wire or sensed object 2 as a sensor, and such sensor may be disposed adjacent or proximate fiberglass rod 3.

(19) In some other aspects, draper belt carcass 7 includes an embedded radio frequency identification tag (RFID tag) 8 and associated transverse antenna disposed within a cleat located proximate the embedded RFID tag. The draper belt carcass 7 may further include an embedded RFID tag 5 and associated longitudinal antenna disposed within V-guide 4.

(20) In yet other aspects, the draper belt may include an embedded wire or sensed object 6 as a sensor, and such sensor may be disposed within V-guide 4. In some cases, draper belt includes embedded wire or sensed object 9 within the carcass 7.

(21) Use of any single sensor arrangement or suitable combination of sensor arrangements described is within the scope and spirit of the disclosure. Further, the embedded sensor objects may be conductive elements, magnetic elements, optically reactive elements, an electronic tag that exchanges data with a RFID reader through radio waves, and the like. The materials forming the sensor objects may be metallic, nonmetallic, or combinations thereof.

(22) In addition to the draper belt types described above, uses of the inventive concepts in other belts, such as hay merger belts and conveyor belts, and the like, are included within the scope of the disclosure.

(23) The foregoing description of the embodiments has been provided for purposes of illustration and description. Example embodiments are provided so that this disclosure will be sufficiently thorough, and will convey the scope to those who are skilled in the art. Numerous specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of embodiments of the disclosure, but are not intended to be exhaustive or to limit the disclosure. It will be appreciated that it is within the scope of the disclosure that individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.

(24) Also, in some example embodiments, well-known processes, well-known device structures, and well-known technologies are not described in detail. Further, it will be readily apparent to those of skill in the art that in the design, manufacture, and operation of apparatus to achieve that described in the disclosure, variations in apparatus design, construction, condition, erosion of components, gaps between components may present, for example.

(25) Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as first, second, and other numerical terms when used herein do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.

(26) Spatially relative terms, such as inner, outer, beneath, below, lower, above, upper, and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as below or beneath other elements or features would then be oriented above the other elements or features. Thus, the example term below can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

(27) Although a few embodiments of the disclosure have been described in detail above, those of ordinary skill in the art will readily appreciate that many modifications are possible without materially departing from the teachings of this disclosure. Accordingly, such modifications are intended to be included within the scope of this disclosure as defined in the claims.
