They generally hold one or two small photographs or a keepsake item such as a lock of hair.
SUMMARY OF THE INVENTION
This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.
In one embodiment, a locket is provided that includes a chamber and a door covering the chamber, with the chamber housing an electronic display, a microprocessor with associated memory coupled to the display, a wireless transceiver coupled to the microprocessor, and a power source. In one embodiment, the chamber is made at least partially of a precious metal such as gold or silver, and the door is made at least partially of a precious metal such as gold or silver, or of crystal, quartz, or mother-of-pearl, or a precious or semi-precious stone. In one embodiment, the electronic display is an LCD display no more than two inches by two inches in size. In another embodiment, the electronic display is an LCD display of approximately one inch by one inch in size. In one embodiment, the battery is a rechargeable battery. The rechargeable battery may be recharged using a hardwire connection provided to the locket, or the locket may be provided with an induction coil and the battery may be recharged using a surface (induction) charger.
In one embodiment, a system is provided that includes the afore-described locket having the chamber, door, electronic display, microprocessor, wireless transceiver and power source. The system further includes a mobile unit such as a cell phone having a locket application and a wireless transceiver, and an application server device with a database. In one embodiment, the system may also include a separately networked device such as a desktop, laptop, or other computer.
According to one embodiment, upon purchase (or receipt) of the locket, a user could log into the application server device, register the locket, and create a profile for themselves. Login could be established via a mobile phone, or a networked device such as a desktop, laptop, or other computer. The profile could establish one or more of interests, personal information, social connections, etc., that would establish how the locket can receive content. For example, the profile could indicate that the user is religious and would like to receive a message or picture with religious content every morning at 6 AM. Alternatively, or in addition, as another example, the profile could identify the email addresses of one, two, or more people (“friend(s)”) from whom the user is willing to receive pictures and/or messages on the locket. The user could also provide a default picture for the locket. The personal information kept in the profile may include an email address for the user and a mobile telephone number. All of the information regarding the profile is stored on the application server device. In one embodiment, the user might then download an application (“a locket app”) for a mobile device that the user is likely to keep near herself, e.g., a mobile phone. The mobile device may then be synchronized (synched) to the locket via the wireless transceivers. For example, each transceiver may be a BLUETOOTH transceiver (Bluetooth being a trademark of the Bluetooth Special Interest Group, of Kirkland, Wash.) using a BLUETOOTH standard protocol. Thus, upon registration and generation of a profile, the application server device may send a message (e.g., a default picture selected by the user that may have been uploaded to the application server device by the user) to the mobile device. If the locket is on or is turned on, the message is then forwarded to the locket using the BLUETOOTH protocol, and the locket can then display the message on the LCD display.
In one embodiment, when a “friend” wishes to send the locket user a picture or message, the friend can access the application server device and upon establishing their identity, can upload the picture and/or message for delivery to the locket of the user. In one embodiment, if the user's profile permits receipt of a picture and/or message from the friend, the picture and/or message is forwarded to the mobile device of the user utilizing the “locket app” synching. Then, when the user turns on the locket, or if the locket is kept on, the mobile device will forward the picture and/or message to the locket utilizing the transceivers, and the picture and/or message will appear on the LCD display.
In one embodiment, the user may set her profile to keep a friend's message or picture for a predetermined amount of time until the default message or picture reappears. In another embodiment, the user may generate a message from the locket or from the mobile device to reset the display. In another embodiment, the profile may keep a friend's message or picture until another message or picture is received.
In one embodiment, the locket is provided with an on-off switch that is activated when the locket is opened. In other words, the electronics of the locket is turned off when the door of the locket is closed, and the locket turns on when the door is opened.
Additional aspects of the subject disclosure will become evident to those of ordinary skill in the art upon reference to the drawings, specification, and claims hereof.

In one embodiment, an on-off switch 75 is provided in or adjacent to the chamber 20. The switch 75 is operatively coupled to the microprocessor 50 and can be configured to selective turn on/off one or more of the LCD display 40 and the transceiver 60. In one embodiment, the switch 75 is activated by the door 30 such that when the door of the locket is closed, the electronics are turned off, and when the door is opened, the electronics are turned on. By way of example, the switch, in a first position may interrupt a power supply circuit to the elements that are turned off, and in a second position, the power supply circuit is completed.
Turning now to FIG. 4, a diagram of a system 100 is provided incorporating an electronic display locket 10, a mobile unit 110 with a locket app, and an application server device 210. More particularly, a mobile unit 110 such as a cell phone, an iPAD (a trademark of Apple, Inc. of Cupertino, Calif.), or similar device is provided with a short range wireless transceiver 112 such as a BLUETOOTH transceiver. As suggested by FIG. 4, the transceiver 112 of the mobile unit 110 and the transceiver 60 of the electronic display locket 10 can communicate with each other. In addition, the mobile unit 110 supports wireless communication over a cell-based radio access network 114 that includes base stations 115 and corresponding controllers 116 that interface to a packet switched core network 118 that is connected to an IP access network and the Internet 119. The mobile unit 110 is also provided with a locket app that may be downloaded to the mobile unit 110 via the radio access network 114 as described hereinafter. In one embodiment, the system may also include a separately networked device such as a desktop, laptop, or other computer 130 that is coupled to the Internet 119. The mobile unit 110, and where utilized, the networked computer 130 include software suitable for interacting with the cloud service utilizing networked communication.
The communication network(s) 114, 118, 119, as well as the operating system of the mobile unit 110 and the networked computer 130 can provide support for TCP/IP networking and suitable messaging protocols in order to communicate messages and/or data between such devices and the cloud service. Those skilled in the art will recognize that the complete structure and operation of communication networks and other components within the system are not depicted or described. Embodiments may be employed in conjunction with known communications networks and other components.
The system of FIG. 4 incorporates the application server device 210 and associated database 230. In conjunction with the database 230, the application server device 210 can communicate with the locket app, executing on the mobile unit 110 in order to perform multiple tasks and allowing access by the user of the locket and friends of the user to perform multiple tasks. While not shown, mobile units and/or networked computers of friends may also be connected via either or both of the radio access network 114 and the Internet 119 to the application server device 210. In addition, while not shown, a single application server device 210 may be used to service the functionality of numerous (e.g., thousands or tens of thousands or more) different electronic display lockets.
In one embodiment, for each electronic display locket, the application server 210 is suitably configured to: register the electronic display locket, receive and store a profile for the locket user, provide a locket app to the mobile unit and/or networked computer of the user, determine whether a contact providing messages and/or pictures is a friend of the user, receive messages and/or pictures from friends of the user, and exchange data with the mobile device 110 of the user via the radio access network 114 in order to load data representing messages and/or pictures onto the mobile unit. Once loaded onto the mobile unit 110, the messages and/or pictures can be communicated to the locket 10 via the wireless link therebetween for visual display on the display screen 40 of the locket 10.
In one aspect, each electronic display locket 10 may be provided with a unique serial number or code that identifies that locket. When a user acquires the locket, and as seen in FIG. 5, that identification may be provided to the application server 210 by contacting the application server 210 and providing the identification at 302. The electronic display locket will then be registered. The user may be asked at 304 to provide and may provide a password or other code for security purposes that may be used upon logging into the server.
In one aspect, once an electronic display locket is registered, the user (owner) of the locket may generate a user profile at 306. The profile may establish one or more of interests, personal information, social connections, etc., that would establish how the user's locket can receive content. For example, the profile could indicate that the user is religious and would like to receive a message or picture with religious content every morning at 6 AM. That message or picture may be provided by the application server provider or a subcontractor and stored in memory associated with the application server device for delivery at the desired time. Alternatively, the profile could indicate that the user enjoys surprises and would like images, words, quotations, etc. provided to the locket at random times. The application server could then access a database of images, words, or quotations and deliver the same at random times. Alternatively or in addition, as another example, the profile could identify the email addresses of one, two, or more people (“friend(s)”) from whom the user is willing to receive pictures and/or messages on the locket. The user could also provide a default picture for the locket. The personal information kept in the profile may include an email address for the user and a mobile telephone number. All of the information regarding the profile is stored in the database 230 associated with the application server device 210.
In one aspect, once an electronic display locket is registered, at 308 the user might then download from the application server device 210 an application (“a locket app”) for a mobile device that the user is likely to keep near herself, e.g., a mobile phone, and that
In one aspect, at any time after the electronic locket is registered and the user has obtained the locket app for her mobile device, if a message is to be sent at 310, the mobile device may be synchronized (synched) by connecting at 311 to the application server device 210 and by downloading the message at 313. This may be done in a manner chosen by the user or according to a default mechanism. For example, the user might choose to actively generate a synchronization by accessing the app on the mobile device 110 and hitting “synch”. Alternatively, as long as the app is running on the mobile device 110, the application server device 210 may periodically synch. Upon synchronization, the application server device 210 may send a message at 313 (e.g., a default picture selected by the user that may have been uploaded to the application server device by the user) to the mobile device.
In one aspect, when a message from the application server device 210 is provided to the mobile device 110, the application server may also send a text message alert (or a text message may be automatically be generated by the app) to the mobile device 110 that notifies the user that a message or picture is available. For example, the alert might say “Message Waiting”. As another example, the alert might use a trademark phrase such as “WHAT'S IN MY LOCKET?” in order to notify the user that a message or picture is being provided for display.
In one aspect, for a registered electronic locket, once a message or picture is has been sent to the mobile device 110 for display on the locket, if the locket is on or is turned on and within range of the mobile device 110, the locket and mobile device are synched by connecting at 315 and by forwarding the message to the locket using the BLUETOOTH protocol at 317. The locket can then display the message on the LCD display at 317. In other words, the electronic display locket 10 will synch to the mobile device 110 and receive the message for display. In one embodiment, the user may control the synching of the locket 10 to the mobile device 110 with a control button on the locket. In another embodiment, the user may control the synching of the locket 10 to the mobile device 110 by actively generating a synchronization via the locket app on the mobile device 110.
In one aspect, when a “friend” wishes to send the locket user a picture or message, the friend can access the application server device 210 at 331, and upon establishing their identity, can upload (either directly, or using an app provided by the application server device 210 to the friend) the picture and/or message for delivery to the locket of the user. In one embodiment, based on a look-up in the profile of the user at 333, if the user's profile permits receipt of a picture and/or message from the friend, the picture and/or message is received from the friend at 335 and forwarded to the mobile device of the user utilizing the “locket app” synching. In one embodiment, the friend may establish the timing of the forwarding of the picture and/or message. Then, immediately, or at an appropriate time, when the user turns on the locket, or if the locket is kept on, the mobile device will forward the picture and/or message to the locket utilizing the transceivers, and the picture and/or message will appear on the LCD display as previously described.
In one embodiment, the user may set her profile to keep a friend's message or picture for a predetermined amount of time until the default message or picture reappears. In another embodiment, the user may generate a message from the locket via a reset button or the like (not shown) or from the mobile device 210 using the locket app to reset the display. In another embodiment, the profile may keep a friend's message or picture until another message or picture is received.
In one embodiment, the locket has no control buttons for use by the user that impact the receiving or displaying of messages or pictures.
In one embodiment, the locket may have a single button for use by the user for controlling an aspect of the receiving or displaying of messages or pictures.
In one embodiment, the locket may have a button for use by the user that controls the opening of the locket.
In one embodiment, the locket may have a button for use by the user that controls the powering on or off of the locket.
According to one aspect, the locket may be worn on a wrist and appear to be a wristwatch with a cover.
