2. Description of the Related Art
There has been a large increase in the number of electronic devices used by the typical consumer. These devices include cell phones, PDA's, mp3 players, GPS devices, cameras, beepers, remote controls, cordless phones, calculators, etc. The rapid pace at which new technology and models of electronic devices are introduced creates a situation where many consumers upgrade or replace one or more recyclable device on a frequent basis. Often, the consumer does not dispose of the prior electronic device, but rather just stops using it and begins using the new device. This may happen over several generations of such devices.
In addition to the electronic devices mentioned above, there are many other types of devices that have relatively high frequency replacement rates, including portable mobile electronic devices, such as cell phones, MP3 players, etc, and non-portable electronic devices, such as computers, printers, and the like. In addition to electronic devices, there are content based digital media such as games on CD, DVD, or cartridge, or entertainment mass storage items such as CDs, DVDs, BluRay, etc. There is a need for handling of such items in an ecologically friendly manner, both via recycling or by proper disposal procedures. It has not been convenient for owners of electronic devices to either recycle such devices or to properly dispose of such devices. There is currently little incentive for a device owner to “do the right thing” with a used device. When the owner just stops using a device and simply puts it in storage: the opportunity for recycling or re-use by another party is lost. If the owner just throws the device away in normal trash containers, the proper recycling or safe disposing of the device is thwarted.
One particular problem associated with this phenomenon can be illustrated by an example of mobile phones. There are more than 3.6 billion mobile phone users in the world with an annual growth of 10% per annum. The replacement rate of mobile handsets is roughly every 18 months as new models have more features and new standards evolve. Wireless carriers also offer new phones below cost, or free, as incentives to get customers to sign lucrative two-year service contracts ensuring a constant build-up of old mobile phones. Old mobile phones and other mobile devices (pagers, PDAs) present a growing threat to the environment. As of 2007, there are more than 750 million mobile phones waiting to be recycled in the US, either in drawers or already in the waste stream. Another 150+ million or so are added every year. Once in the waste stream, these devices may leak Lead, Mercury, Cadmium, Arsenic and other toxic substances into the water supply. Municipalities often incinerate their waste, instantly putting these toxic elements into the air, and they return to earth in rain water. A problem that needs to be solved is to make it easy and accessible for the public to recycle or resell their mobile phones and other recyclable devices. Two reasons why mobile phones are not being recycled or resold are difficult access to recycling or reselling facilities, and secondly security concerns about the information stored on the mobile phone. In addition to mobile phones, the same problems apply to many other electronic devices.
Technology has not yet provided a resolution to this problem. One invention is Bishop, U.S. Pat. No. 4,951,308 for Automated Vending Of Cellular Hand-Held Telephones And Cellular Telephone Services, which discloses a vending machine that dispenses cellular telephones purchased by consumers through the vending machine. Bishop essentially adds to the problem by making it easier to acquire mobile phones.
Taylor et al., U.S. Patent Publication Number 2009/0190142, for a Method And System For Connecting A Data Storage Device To A Kiosk, discloses a kiosk with a docking port and an optical recognition device for identifying a data port on a data storage device. Taylor is directed at printing digital images at a photo kiosk.

If the electronic device is supported for refurbishment/resale the customer is then encouraged to engage the testing/rating operation of the system. At step 304, the system has determined the correct connector to couple to the electronic device. Connectivity options and are not limited to cable, standard or proprietary connectors, hard docks, reading removable or external physical memory or other wireless methods like WiFi, Bluetooth, RFID, NFC, and the like. At step 305 the electronic device is connected and inserted into inspection area 106. If this has been done correctly, the customer is given some indication (e.g. a green light) and the system proceeds to step 306. At step 306 the electronic device is tested for operation using diagnostics and operating via, for example, the OMSI interface. The diagnostics preferably includes electrical and physical testing including testing the electronic device's battery, screen, memory, button functionality and structural integrity.
Preferably, the electronic device is imaged and analysis software is used to identify scratches, cracks, wear patterns, dents, broken or missing pieces, inclusion of features such as lenses, buttons, connectors, badges, labeling and/or branding. Identification may be done by image comparison or other similar methods where the image taken of the electronic device is normalized and compared to a reference image. Other inspection methods may be used in conjunction with visual and/or electrical testing including weighing to determine specific weight and use that data to further refine verification of manufacturer and verification of exact device model. In another embodiment, the photographic image is used to identify the correct manufacturer and model number/product number. Visual identification could include any combination of the following: calculations based upon measurement, physical (e.g., mm, inches), pixel count or other. Identification based upon electronic device dimensions, location/size of buttons, LCD and other physical characteristics. One camera or multiple cameras may be used to determine height, width, depth as needed. Identification based on OCR (Optical Character Recognition) of identifiers such as Carrier (for phone and tablet computers), brand, model, serial number, other identifiers. Identification based upon barcodes. Consumer may be asked to orient CE on its front, back, side and then asked to change orientation as needed. Consumer may even be asked to remove CE cover(s), batteries and the like in order to gain access to identifiable items, such alphanumeric or barcode data. The kiosk 100 provides a way to use visual inspection with electrical inspection to identify a device, determine its value, and reduce possible fraud.
In one embodiment, the kiosk 100 communicates with the carrier associated with a mobile phone to collect any information that could be germane to the device, including, for example, validation or authentication, registered ownership, account status, time in service, and the like. In some cases, when the customer's identification information does not match the registered owner information, the kiosk 100 automatically contacts the assumed owner in some manner (automated telephone call, email, text message, etc.) to alert the owner of the phone of the possible transaction.
Another feature of an embodiment of the kiosk 100 is to determine if there is personal information on the electronic device. This is determined by the presence of data in particular storage registers in the memory (e.g., quick-key stored numbers) or by looking at file types (jpegs, mp3's, etc.,), or just assuming all non-default storage locations must contain personal data. The customer is offered the chance to erase the data from the phone. One option allows the customer to request that the data be first downloaded and then sent to a location designated by the customer (e.g., email address, website, etc.). In another embodiment, there is a slot for the customer to enter a memory card (e.g. USB drive memory stick, etc.) whereupon the kiosk 100 uploads the data to the memory device. In still another embodiment, the kiosk 100 offers a web location from which the user retrieves the data at some later time if desired. In another embodiment, the user elects to have the data placed in another electronic device purchased by the customer at the kiosk 100 or in the location of the kiosk 100 or some other store. The customer preferably selects a user name and password to access the system provided storage location.
Once the value is determined, the value is provided at step 307 to the kiosk. The kiosk 100 then offers the customer a price or other remuneration for the phone that is typically less than the resale value. In other embodiments, the kiosk 100 offers the customer a price or remuneration that is at the current real-time market price. At step 308 it is determined if the user wishes to accept the offer. If not, the kiosk 100 proceeds to step 309 and opens the door and releases the electronic device back to the customer. If the user wishes to accept the offer, the kiosk 100 proceeds to step 310. At a point where the user accepts a price, the kiosk 100 may then lock down the inspection area to prevent further access to the electronic device by the user. The kiosk 100 then disconnects any cables that have been attached. At step 310, the user indicates acceptance of the decision by confirming on the keypad or touch-screen. At this point the kiosk 100 proceeds with deleting the personal data from the electronic device. In addition, once the transaction is confirmed, the kiosk 100 tags the electronic device with a transaction number that is associated with the diagnostic data and the transaction itself. This is preferably a printed adhesive label that is affixed physically to the phone and/or the loading of electronic data corresponding to the transaction number onto the phone itself for traceability purposes.
At step 311, the kiosk 100 completes any additional testing and diagnostics of the electronic device, disconnects the cable from the electronic device, and prints a receipt for the customer. Transfer of funds may be authorized via the kiosk 100 by crediting a customer credit card or account by dispensing cash, or by dispensing a voucher or coupon. At step 312 the kiosk 100 updates its inventory database and transmits the update via a communications network to a kiosk server.
