Technologies and concepts discussed herein relate to portable devices for use in retail establishments. In an exemplary embodiment, a portable device is secured in a cradle. A user with a customer loyalty card having a radio-frequency identification (RFID) tag uses the card to release the portable device from the cradle.



FIG. 1 illustrates a block diagram of one embodiment of a system 100 according to the invention. The system 100 includes a portable device 102, a network 104, a server 106, and a cradle 108. A potential user of the portable device 102 must unlock the portable device 102 from the cradle 108 prior to using the portable device 102.


The portable device 102 includes a display 110 for displaying information relating to user identification, account information, location information, product information, service information, advertisements, coupons, marketing, or any other information relevant to the shopping experience in the store. A transceiver 112 connects the portable device 102 to the network 104 by providing communication functionality for the portable device 102. The portable device 102 can also include a radio-frequency identification (RFID) reader module 114 for reading RFID tags located within range of the RFID reader module 114. For example, an RFID tag containing product information can be secured to a product or located within the packaging of the product. The product information can include price, quantity, nutritional information, weight, date of manufacture, or any other desired information. As will be discussed herein, the RFID reader module 114 can also trigger a locking mechanism 116 on the cradle 108 to unlock the portable device 102 from the cradle 108.


In one embodiment, a customer loyalty card 120 including a radio-frequency (RFID) tag 122 can be positioned within range of the RFID reader module 114. The RFID tag 122 can include customer data, such as registration information. The RFID reader module 114 can read the customer data from the RFID tag 122. The data can be transmitted by the portable device 102 through the network 104 to the server 106. The server 106 can access a database including user registration information to verify that the customer is registered in the database 124. The server 106 sends a signal to the portable device 102 indicating whether or not the user is authorized to use the portable device 102. The customer loyalty card 120 could be any object containing an RFID tag, such as a credit card, membership card, club card, speed pass token, or any other suitable object.


The portable device 102 can also include a battery 126. The battery 126 provides power to the electronic components of the portable device 102. The battery 126 can be a rechargeable battery, such as a lithium ion, nickel metal hydride, or nickel cadmium, for example.


The portable device 102 also includes one or more input/output (I/O) devices 128 such as a keyboard with alpha-numeric keys. Other I/O elements can include soft and/or hard keys, a touch screen, a joystick, a trackball, a thumbwheel, an optical mouse, a touch pad, a jog wheel, an optical control, and/or a pointing device, a microphone, and a speaker, for example. In some embodiments, the portable device 102 includes more or less than all of the aforementioned I/O elements. Components of the portable device 102 will be discussed in more detail herein with reference to FIG. 2.


The server 106 can be a stand-alone computer coupled to the network 104 and the cradle 108. Alternatively, the server 106 can be integrated with the cradle 108. The server 106 can be a personal computer (desktop or laptop), a handheld computer, a Personal Digital Assistant (PDA), or a cellular phone, for example. The server 106 can include a memory 130, a processor 132, a storage device 134, a network connection module 136, and input/output devices 138 such as a display, a mouse, a printer, and/or a keyboard.


The server 106 also includes a software application 140 that receives requests from the portable device 102. The requests can relate to verifying an identity and/or registration of a user. The software application 140 can communicate with the database 124 that contains user data. The database 124 can reside on the server 106 or alternatively, can be remotely located from the server 106. The software application 140 can also provide functionality relating to retrieving product information. In practice, the software application 140 can provide any desired functionality. Various techniques for accessing information stored in the database 124 can be used without departing from the invention.


The server 106 can also include server software that can track the charge level of the battery 126. In one embodiment, the server software can transmit commands to a portable device 102 located in a cradle 108 to change the portable device's status in response to the charge level of the battery 126. The status change can be indicated on the portable device 102 and/or on the cradle 108. For example, if the charge level of the battery 126 is above an acceptable user- defined threshold, the server software can command the portable device 102 to change the status indicator from “not ready” to “ready” indicating that the portable device 102 is ready for use. Alternatively, if the charge level of the battery 126 is below an acceptable user-defined threshold, the server software can command the portable device 102 to change the status indicator from “ready” to “not ready” indicating that the portable device 102 is not ready for use and/or that the battery 126 is charging.


The network connection module 136 can include hardware and software required to connect the server 106 to the network 104. The network 104 can be any network, such as a Wide Area Network (WAN) or a Local Area Network (LAN), or any other network including a cellular network. The WAN may include the Internet, for example. A LAN may include an Intranet, for example.


The cradle 108 is adapted to receive the portable device 102. For example the cradle 108 can include a mating feature that mates with a corresponding mating feature on the portable device 102. The cradle 108 includes an electrical connector that mates with an electrical connector on the portable device 102. The electrical connectors can facilitate the transmission of signals between the cradle 108 and the portable device 102. Alternatively, the cradle 108 and the portable device 102 can communicate wirelessly through a wireless network, such as a Bluetooth or a ZigBee network, for example.


The cradle 108 also includes the locking mechanism 116 that can secure the portable device 102 to the cradle 108. In one embodiment, the locking mechanism 116 includes a solenoid having an actuator that engages with a mechanical feature on the portable device 102 to lock the portable device 102 to the cradle 108. Alternatively, the actuator of the solenoid can be coupled to a mechanical feature of the cradle 108 that engages a mechanical feature of the portable device 102. The actuator can be a linear actuator or a rotary actuator.


In one embodiment, the mechanical feature of the cradle 108 can be a spring loaded latch such that when the portable device 102 is placed in the cradle 108, an audible click is heard indicating that the portable device 102 is locked in the cradle 108. Skilled artisans will appreciate that various techniques can be used to secure the portable device 102 to the cradle 108 without departing from the invention. For example, in addition to mechanical securing techniques, the portable device 102 can be secured to the cradle 108 using an electro-magnetic mechanism. In practice, any suitable locking mechanism can be used.


The cradle 108 can also include a battery charging circuit 142. The battery charging circuit 142 can include an electrical connector that mates with an electrical connector accessible on the portable device 102. The battery 126 in the portable device 102 is charged when the portable device 102 is placed in the cradle 108. In one embodiment, the battery charging circuit 142 can include a wireless charging coil. The portable device 102 can include a complementary coil. The wireless charging coil can wirelessly charge the portable device 102 when the portable device 102 is placed in the cradle 108.


The cradle 108 can also include an indicator 144. The indicator 144 can include one or more light emitting diodes (LED's). The LED's can indicate a status of the portable device 102. For example, a green LED can indicate that the portable device 102 is ready for use. An orange LED can indicate that the battery 126 in the portable device 102 is charging. A red LED can indicate that the portable device 102 is not ready for use. In another embodiment, the indicator 144 is a display, such as an LCD display or an e-ink display. In practice, the indicator 144 can be a lamp, a LED, a display, a speaker, or any other suitable indicator.


The indicator 144 can also display information relating to a user. For example, the indicator 144 can indicate that a user is authorized to use a specific portable device 102. In one embodiment, the indicator 144 can indicate that the user should report to the customer service counter.


The cradle 108 can optionally include a RFID tag 146. The RFID tag 146 can include data relating to a location of the cradle 108, for example. The RFID tag 146 can be read by the RFID reader module 114 of the portable device 102. The portable device 102 can transmit the data from the RFID tag 146 to the server 106.


The portable device 102 can be a mobile computer, a personal digital assistant (PDA), a cellular telephone or a satellite telephone, for example. The portable device 102 includes electronic components, including internal communication components and circuitry as further described with relation to FIG. 2 to enable the portable device 102 to function and to communicate wirelessly with other devices including a host device.



FIG. 2 is a block diagram 200 illustrating the electronic components of the portable device 102 (FIG. 1) according to the invention. The portable device 102 contains, among other components, a processor 202, a transceiver 204 including transmitter circuitry 206 and receiver circuitry 208, an antenna 222, the I/O devices 212 described in relation to FIG. 1, a program memory 214 for storing operating instructions that are executed by the processor 202, a buffer memory 216, one or more communication interfaces 218, an integrated display 228, a battery 230, an optional removable storage 220, and a radio-frequency identification (RFID) reader module 226 coupled to the portable device 102.


The RFID reader module 226 is integrated with the portable device 102 (FIG. 1) for reading an RFID tag located within range of the RFID reader module 226 of the portable device 102, for example. In some embodiments, a motion tracking module (not shown), such as an accelerometer or global positioning system (GPS) can be used to track a location and/or an orientation of the portable device 102.


In one embodiment, the portable device 102 is an integrated unit containing the components depicted in FIG. 2, as well as any other component necessary for the portable device 102 to function. In one embodiment, the electronic components are connected by a bus 224.


The processor 202 can include one or more microprocessors, microcontrollers, DSPs, state machines, logic circuitry, or any other device or devices that process information based on operational or programming instructions. Such operational or programming instructions are preferably stored in the program memory 214. The program memory 214 can be an IC memory chip containing any form of random access memory (RAM) or read only memory (ROM), a floppy disk, a compact disk (CD) ROM, a hard disk drive, a digital video disk (DVD), a flash memory card or any other medium for storing digital information. Skilled artisans will recognize that when the processor 202 has one or more of its functions performed by a state machine or logic circuitry, the program memory 214 containing the corresponding operational instructions may be embedded within the state machine or logic circuitry. Operations performed by the processor 202 as well as the portable device 102 are described in detail below.


The transmitter circuitry 206 and the receiver circuitry 208 enable the portable device 102 to respectively transmit and receive communication signals. In this regard, the transmitter circuitry 206 and the receiver circuitry 208 include circuitry to enable wireless transmissions. The implementations of the transmitter circuitry 206 and the receiver circuitry 208 depend on the implementation of the portable device 102 and the devices with which it is to communicate. For example, the transmitter and receiver circuitry 206, 208 can be implemented as part of the communication device hardware and software architecture in accordance with known techniques. One of ordinary skill in the art will recognize that most, if not all, of the functions of the transmitter or receiver circuitry 206, 208 can be implemented in a processor, such as the processor 202. However, the processor 202, the transmitter circuitry 206, and the receiver circuitry 208 have been partitioned herein to facilitate a better understanding of the functions of these elements. The antenna 222 can be a WAN or a LAN antenna or a cellular network antenna coupled to the transceiver 204.


The buffer memory 216 may be any form of volatile memory, such as RAM, and is used for temporarily storing information received from the remote server 106, (FIG. 1) for example. The removable storage 220 can be a secure digital (SD) memory card, for example.


The display 228 displays data generated by software applications residing in the memory 214 and executing on the processor 202 as well as customer information and/or product information received from the remote server 106. The display 228 can be a liquid crystal display (LCD) or any other suitable display. In one embodiment, the display 228 is a touch screen display having user input capabilities. For example, the user can touch the surface of the display 228 to activate a function of the device 102.



FIG. 3 is a flowchart 300 illustrating one mode of operation of a system in accordance with the invention. In a first step 302, a user approaches the portable device 102 and waves a customer loyalty card 120 (FIG. 1) proximate to the portable device 102. In step 304, the RFID reader module 114 in the portable device 102 reads the RFID tag 122 in the loyalty card 120 to extract user data from the RFID tag 122. A software application executing on the processor 202 (FIG. 2) instructs the transceiver 204 to transmit the user data to the server 106. The server 106 accesses a database 124 containing data for all the registered users in the system. The server 106 verifies that the user requesting to use the portable device 102 is registered in the database 124 (step 306). In some embodiments, the server 106 can also provide other functionality such as whether the user is entitled to coupons, rebates, or other special programs.


If the server 106 determines that the user is not registered in the database (step 308), the server 106 can transmit a “do not release” signal to the portable device 102 (step 310). The portable device 102 can send a signal to the indicator 144 on the cradle 108 indicating that the user is not authorized to use the portable device 102. The indicator 144 can be a red LED, for example. In another embodiment, the indicator is a display that indicates that the user should proceed to customer service. The process ends (step 312) and the portable device 102 remains locked in the cradle 108.


If the server 106 determines that the user is registered in the database (step 308), the server 106 can transmit a “release” signal to the portable device 102 (step 313). A software application executing on a processor in the portable device 102 checks the battery status of the portable device 102 to determine if the battery capacity is adequate (step 314). If the battery capacity is adequate, the software application can activate an indicator 144 on the corresponding cradle 108 that houses the portable device 102 (step 316). The indicator 144 indicates the location of the portable device 102 and the status of the portable device 102. For example, the indicator 144 can be a green LED indicating that the portable device 102 is ready for use.


In one embodiment, multiple cradles 108 each securing a portable device 102 can be located together. In this embodiment, the indicator 144 on the cradle 108 with the portable device 102 having the highest battery capacity compared with the other portable devices 102 can be activated indicating that the portable device 102 is ready for use. In other embodiments, two or more indicators 144 can be activated, thereby giving a user a choice of several portable devices 102 that are ready to use.


The portable device 102 also sends a signal to the cradle 108 to unlock the portable device 102 (step 318). For example, the processor in the portable device 102 can command the locking mechanism 116 of the cradle 108 to release the portable device 102. In one embodiment, several portable devices may simultaneously be ready for use and in an unlock state in their corresponding cradles. In this embodiment, once a user removes a particular portable device from a cradle 108, the locking mechanisms of the other cradles will immediately secure the other portable devices.


In step 320, the user removes the portable device 102 from the cradle 108. In step 322, the user can return the portable device 102 to an empty cradle 108, or alternatively, a store employee can return the portable device 102 to an empty cradle 108. It should be noted that the portable device 102 can be returned to any empty cradle 108 and not necessarily to its original cradle 108.


Once the portable device 102 is returned to the cradle 108, the portable device 102 can register itself with the server 106 (step 324). For example, the portable device 102 can upload information to the server, such as last shopping event data, the current location of the portable device 102 (e.g., current cradle information), battery status, or any other desired information. In the event that the battery requires charging, the portable device 102 can command the charging circuit in the cradle 108 to begin charging the battery in the portable device 102 (step 326). Alternatively, the battery charging circuit can be activated by default when the portable device 102 is positioned in the cradle 108.

Referring to FIG. 4A, the portable device 402 includes a housing 403, and display 406 and a plurality of input keys 408. The portable device 402 can also include a mechanical feature 410 that mates with a corresponding mechanical feature 412 of the cradle 404 to secure the portable device 402 in the cradle 404. The portable device 402 can also include electrical contacts 414 that mate with electrical contacts (not shown) on the cradle 404.


The cradle 404 includes a slot 416 for receiving the portable device 402. In one embodiment, the slot 416 is a mating feature shaped to conform to a mating feature (a portion of the housing 403) portable device 402. The cradle 404 also includes a port 418, such as a universal serial (USB) port for connecting the cradle 404 to other cradles or a host device. In one embodiment, the cradle 404 is also coupled to a network, either wirelessly or through a wired connection to the port 418.


The cradle 404 can also include an indicator 420. The indicator 420 can be a lamp, a LED, a display, a speaker, or any other suitable indicator. The indicator 420 can indicate a status of the portable device 402, for example.


In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below. Accordingly, the specification and figures are to be regarded in an illustrative rather than a restrictive sense, and all such modifications are intended to be included within the scope of present teachings. The benefits, advantages, solutions to problems, and any element(s) that may cause any benefit, advantage, or solution to occur or become more pronounced are not to be construed as a critical, required, or essential features or elements of any or all the claims. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.


Moreover in this document, relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The terms “comprises,” “comprising,” “has”, “having,” “includes”, “including,” “contains”, “containing” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises, has, includes, contains a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by “comprises . . . a”, “has . . . a”, “includes . . . a”, “contains . . . a” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises, has, includes, contains the element. The terms “a” and “an” are defined as one or more unless explicitly stated otherwise herein. The terms “substantially”, “essentially”, “approximately”, “about” or any other version thereof, are defined as being close to as understood by one of ordinary skill in the art, and in one non-limiting embodiment the term is defined to be within 10%, in another embodiment within 5%, in another embodiment within 1% and in another embodiment within 0.5%. A device or structure that is “configured” in a certain way is configured in at least that way, but may also be configured in ways that are not listed.


It will be appreciated that some embodiments may be comprised of one or more generic or specialized processors (or “processing devices”) such as microprocessors, digital signal processors, customized processors and field programmable gate arrays (FPGAs) and unique stored program instructions (including both software and firmware) that control the one or more processors to implement, in conjunction with certain non-processor circuits, some, most, or all of the functions of the method and apparatus for securing the portable device described herein.
