Description:
RELATED APPLICATION 
     In accordance with the requirements of 35 U.S.C. 119(e) or 120, and 37 CFR 1.78, Applicant claims the benefit of U.S. Prov. Appl. Ser. No. 62/207,090, filed on Aug. 19, 2015, the disclosures of which are incorporated herein by reference in their entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     Jewelry has traditionally had lockets or closed compartments in which special photographs, images or keepsakes are maintained. Such compartments are generally integrally formed within the jewelry which is often worn as a pendant or necklace with mechanical structure allowing doors, gates or windows to be open to access the photos or allow retrieval of material stored within the compartments. 
     The photo or photos stored in such personal lockets worn by people do not change. It can only be viewed by a person in physical proximity to the locket and there is a limited ability to change the photo(s). Indeed, when photos are changed, old photos are often discarded and replaced with new ones. The ability to update, store or otherwise provide a significant amount of photos or other desirable viewable content is unavailable with current jewelry structures. 
     Modern technology has developed near field communication (NFC) chips which include a set of protocols enabling smartphones and other devices to establish radio communication with each other by touching the devices together or bringing them into proximity to a distance of typically four inches or less, as currently designed. Currently, such devices are made of non-conductive material, and the NFC chip is snugly held in place within the device to minimize wasted space. 
     NFC employs electromagnetic induction between two loop antenna to exchange information between the devices. Data in NFC tags typically are read only, but some also are rewritable. The material in which such NFC chips are snugly held is non-conductive, such as plastic or composite materials. 
     An object of this invention is to provide decorative jewelry housing keepsake items where the keepsake items are easily viewable, susceptible to change and storage and retrieval of a large amount of viewable content, such as images, videos, data or the like. 
     Another object of this invention is to provide such a jewelry item which is made of precious metal, such as gold or silver, which holds an NFC chip without significantly impairing the radio frequency (RF) transmission of the NFC chip. 
     Yet another object of this invention is to provide a metal structure having a compartment within which an NFC chip may be fixed in place, yet be able to use the metal structure with the NFC chip with smart phones and the like. 
     Other objects, advantages and features of this invention will become more apparent from the following description. 
     SUMMARY OF THE INVENTION 
     This invention is directed to a personal jewelry item capable of being worn and housing an NFC device. The NFC device incorporated in the present invention has a ferrite material with the chip having a ferrite casing and a silicone glue to be able to be used. The ferrite casing is metal and is suitable to be a part of a jewelry item. The ferrite material minimally adversely impacts RF transmission. 
     The NFC device sits within a metal compartment and is separated from the walls of the compartment, allowing for a cushion material to be placed therein while still permitting effective RE transmission. 
     Typically, the NFC device will work with an app to a smartphone when the jewelry is placed in close proximity to the smartphone carrying the app. This will be explained in more detail below. Bluetooth may be the communication protocol or other communication protocols may be provided. 
     In use, this invention appears to be an ordinary attractive pendant, but the pendant is constructed so as to enable the NFC chip to be housed within a compartment in a secure manner which enables the chip to securely remain in place while storing and displaying content such as photos, videos, voice clips, GPS locations, birthday reminders, etc.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       FIG. 1A  shows a heart shaped pendant  10  containing a center heart-shaped jewelry locket  12  shown from the front. The jewelry locket is closed without being able to be opened from the front, although one could place a false door in the front of the locket. A separate NFC chip  14  is shown in  FIG. 1B  as is a separate cover  16  in  FIG. 1C  for holding the chip in place. The pendant  10  may be carried on a chain  8 . 
       FIG. 2A  is a rear plan view of the pendant of  FIG. 1A  and shows the open rear  11  of jewelry locket  12  with the chip  14  and cover  16  shown as  FIGS. 2A and 2B  separated from locket  12 . A recess or rear compartment  18  is formed in the rear  11  of the locket  12 . 
       FIG. 3A  is another rear plan view of the heart of  FIG. 1A  showing the NFC chip  14  secured in place by an epoxy or other adhesive material attaching chip  14  in compartment  18 . There may be a cushioning material  20  provided between the chip  14  and walls  25  (see  FIG. 5 ) of the compartment  18  so as to ensure secure attachment and impact minimization of the chip  14 . Cover  16  shown in  FIG. 2C  fits on the rear  22  of the locket  12  to secure the chip in place with the dog ears  24  of the cover  16  fitting into the dog ear recesses  26  in the corners of the rear of the locket  12  as shown in  FIG. 4 . 
       FIG. 4  is a rear plan view of this invention similar to  FIG. 3A  but showing the cover  16  in place holding the chip so as to be shock resistantly held in place and effectively operate. Cover  16  is flush with the rear surface of rear  22 . 
       FIG. 5  is a top view of compartment  18  with NFC chip  14  therein, while  FIG. 6  is a side view of the compartment  18  and chip  14  therein. Dimensions “d” in  FIG. 5  are representative of the dimensional distance between the chip  14  and the side walls  25  of the compartment while dimension “t” is representative of the height of the walls  25  of the compartment in relation to chip  14 . 
       FIGS. 7A, 7B and 7C  are alternative dimensional arrangements as well as cut-outs for the walls of the compartment  18 , all of which may be adjusted and otherwise changed to produce the most effective RF transmission considering that the NFC chip is sitting within a jewelry item made of precious metal, and the walls of the compartment are formed of such precious metal as well. 
     As a preferred embodiment of this invention, a preferred distance “d” is 2 mm and a preferred height “t” is 4 mm. Additionally, cut-outs  74  and  76  shown in  FIGS. 7B and 7C  may also improve the RF transmission characteristics as well as changing the height of the walls  74  and  76  so that they are not equal as shown in  FIG. 7A . 
     This invention may be used with or without the cushioning material  20 , as described above. 
       FIG. 8  is a block diagram of showing the system architecture of an embodiment of the invention which includes smartphones, an NFC chip and cloud storage system. An NFC chip  80  is embodied in locket  12  as described above. The NFC chip could be an MBT tag made by Toda Kogyo Corp. of Japan. An NFC enabled smartphone  84  has a preloaded software application (“app”)  86  which associates the NFC chip with a unique location in a cloud storage system  88  having the unique location associated with the specific NFC chip. 
     In use, the recipient taps his/her smartphone  85  against locket  12  to establish an NFC link, and the smartphone then reads the NFC code which directs App  86  to connect smartphone  85  to the same cloud location related to that NFC code which was originally set when smartphone  84  was first tapped against locket  12 . Thus smartphone  84  is linked to the specific cloud storage location where the stored media can be accessed and displayed on smartphone  85  which was originally set by smartphone  84 . 
     The system works as follows: a person seeking to buy a special jewelry gift arranges to have an app  86  downloaded to the smartphone of the recipient of the gift. The app communicates with the NFC chip  80  when the chip is brought into sufficient proximity with the smartphone so as to read a unique code or identifier from the NFC chip  80 . Once the unique code is read, the app  86  to provides access to a cloud location associated with that unique code. The purchaser of the gift also has access to the unique identifier associated with the NFC chip. Thus, the purchaser (e.g. a spouse) may upload photos and other content to a cloud location identified by the shared unique identifier and display the content on the screen of the smartphone. When the gift recipient taps her smartphone  85  to the locket  12 , the app  86  will automatically associate her phone with the cloud location that is populated by content, such as photos uploaded by the gift purchaser. 
     Content in the unique cloud location can be uploaded by the party or parties who want to upload media to that cloud location. 
     Any NFC chip enabled smartphone could tap any item of jewelry containing an NFC chip with a preloaded unique cloud location and have direct access to that cloud location to download the media stored in that cloud location onto the NFC chip enabled smartphone. 
     This invention will find great appeal to those non-technical individuals who, by merely tapping their smartphone to a jewelry locket carried on a pendant or the like then has access to all the content seemingly magically carried to the smartphone by the locket without the recipient having to do anything more than tap the NFC enabled smartphone to the jewelry item containing the NFC chip. 
     The overall objective of this invention is to allow traditional jewelry wearers who may not be technically proficient enough to employ modern technology to use a special locket that appears to carry an enormous amount of content that can be seen on the screen of a smartphone. 
     The NFC chip, itself, can store media, but media storage on such chips is extremely limited. 
     It is a further object of this invention to provide access to media stored in a cloud specifically associated with an NFC chip which has a unique cloud location associated with that chip. 
     To the user, it appears as though the locket contains unlimited media that can be shown on a person&#39;s smartphone. In reality, this invention provides for communication between a person&#39;s smartphone, which is NFC enabled and which has had an app downloaded to work with NFC devices, so that a unique location correlated with the specific NFC chip will be transmitted to the smartphone which then provides direct access through the app to the cloud in which the unlimited content can be accessed and viewed through the user&#39;s smartphone. 
     This invention may be used with any metal device, especially any jewelry item that can take advantage of the present invention. 
     This invention provides a unique combination of an NFC chip housed within metal, preferably precious metal, but so located as to provide sufficient distance between the walls of the NFC chip and the walls of a metal compartment in which the NFC chip sits. The distances between the perimeter of the chip and the walls of the compartment or the structure of the walls themselves can be designed to enable RF transmission without serious degradation of the transmission characteristics. Preferred embodiments are described in this patent application. 
     It should be understood that the preferred embodiment was described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly legally and equitably entitled.
