BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to recycling of electronic devices. More specifically, the present invention relates to a kiosk for visually analyzing electronic devices and providing remuneration to an owner for recycling of the electronic device.

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.

The prior art has failed to recognize the problems associated with recycling mobile phones in a manner that is enticing to a consumer yet financially rewarding to the recycler. Further, the prior art has failed to provide an automated means for visually inspecting a LCD screen of a mobile phone to determine if the LCD screen is damaged. Additionally, the prior art has failed to provide an automated means for determining if an electronic device submitted for recycling and remuneration is authentic.

The processor also preferably determines a financial remuneration for the submitted electronic device 150 based on the visual inspection, optionally the electrical analysis and data stored in the memory 161 of the kiosk or information provided externally through the external communication component 167.

A flow chart for a preferred recycling method is shown in FIG. 19. At step 301a customer elects to sell or recycle an electronic device. The customer checks to see if the electronic device is supported for sale/refurbishing from a list on the screen of the kiosk. The customer activates the on-screen menu system and either enters the phone model directly or goes through a series of menus to determine if the electronic device is eligible for sale or only for recycling. At decision block 302 it is determined if the electronic device is only available for recycling. If yes, (i.e. it is not on the list of electronic device available for reselling) the customer can insert the electronic device into receptacle at step 303 and the electronic device falls into bin 112 for recycling.

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.

One preferred method of the present invention is illustrated in the flow chart of FIG. 18. The method 1000 begins at block 1001 with a mobile phone 150 positioned within an inspection area, 106 of a kiosk 100 wherein the inspection area has a light. The electronic device is imaged in a deactivated mode. At block 1002, the display screen of the electronic device is imaged, wherein the electronic device is in the active mode and the light in the inspection area 106 is turned off, resulting in an analysis image of the electronic device. At block 1003, the display screen of the electronic device 150 is imaged a second time, however the light in the inspection area 106 is turned on, resulting in a first image of the electronic device. The mobile phone 150 must have a camera function to be placed within a camera mode. At block 1004, the first image of the electronic device is subtracted from the analysis image, generating a subtraction image of the electronic device. At block 1005, the subtraction image is compared to image of the electronic device in a deactivated mode to determine if the display screen of the electronic device has any defects and to define an analyzed electronic device. At block 1006, the value of the mobile phone is determined as discussed in more detail below.

Preferably, the kiosk 100 of the method comprises a housing 105, the housing 105 comprising a user interface on an exterior surface of the housing for the user to input information, an upper dome and a lower dome, wherein the upper dome and the lower dome comprise a plurality of mirrors. The kiosk 100 further comprises an upper chamber camera, a lower chamber camera and a transparent surface. The kiosk 100 further comprises a processor 160 within the housing and in communication with the at least one camera, the processor 160 configured to identify the brand and model number of the electronic device based on at least one of the information from the user and the images from the at least one camera, the processor 160 configured to determine a financial remuneration value for the electronic device.

The upper and lower domes preferably comprise walls composed of mirrors. The dome shaped apparatus further comprises a transparent surface and at least one camera, the camera capable of obtaining a multiple views of an electronic device placed within the dome shaped apparatus. The upper dome preferably comprises an upper chamber camera. The lower dome preferably comprises a lower chamber camera. Preferably, a combination of each of the upper dome and lower dome cameras and the plurality of mirrors allow for an image of the device placed on the transparent surface. Preferably, the combination of each of the upper dome and lower dome cameras and the plurality of mirrors allow for a 360 degree of the electronic device placed on the transparent surface. Preferably, each of the upper dome and lower dome cameras are moveable.

An alternative method of the present invention is illustrated in the flow chart of FIG. 20. The method 2000 begins at block 2001 wherein an electronic device is placed in an inspection area of a kiosk 100, the inspection area 106 having a camera. At block 2002, a portion of the electronic device is imaged, the portion comprising the perimeter of the electronic device, resulting in a perimeter image. At block 2003, the perimeter image of the electronic device obtained by at least one camera disposed in the inspection area is inspected. At block 2004, it is determined if a display screen of the electronic device has any defects and to define an analyzed electronic device. At block 2005 a value for the analyzed electronic device is determined.

The information from the perimeter image preferably includes a model name and location of a LED aperture. Additionally, the processor 160 is configured to automatically adjust the perimeter edge to a rectangular shape, to compensate for screen damages that result in distorted image due to blacking out of certain parts of the screen. The perimeter image comprises a 360 degree image. Information from the perimeter image comprises a location of a USB port, a location of the volume control buttons, a location of the camera button, and a location of the power on and off button. The information from the perimeter image also comprises a location of the camera lens and a logo of the electronic device.

Preferably, visual inspection and recognition software is utilized by the kiosk 100 to analyze a mobile phone 150. In one preferred method, a recognition algorithm is applied to a specific make and model of a mobile phone 150. The visual inspection and recognition software determines the borders of a mobile phone 150 under inspection to determine the external dimensions of the mobile phone 150. The external dimensions are utilized to determine a subset of possible mobile phones from a master database of mobile phones stored in the memory 161 of the kiosk 100 or available online to the kiosk 100 using external communications. The visual inspection and recognition software then preferably uses a set of secondary and tertiary features to further distinguish the mobile phone 150. These secondary and tertiary features can include placement and size of the display screen, placements and size of the keyboard, unique buttons, placement of ports, and other distinguishing features. Once an exact make and model of the mobile phone is determined, the visual inspection and recognition software subtracts an image of the mobile phone 150 from an image of a perfect mobile phone for the same make and model. The result of the subtraction is preferably a quantifiable number of pixels that are calibrated into categories of broken or missing parts, cracked screen, and low, medium or high wear.

Alternatively, the visual inspection is performed using neural network pattern recognition techniques to identify the mobile phone 150, then filter algorithms are utilized to determine defects such as cracked screens. Further, those skilled in the pertinent art will recognize that other visual inspection techniques may be employed without departing from the scope and spirit of the present invention.

Further, visual inspection optionally includes obtaining a heat signature for the mobile phone 150. One preferred method of obtaining a heat signature of a mobile phone 150 is to raster a laser across the mobile phone to characterize a heat decay profile of the submitted mobile phone 150. This heat decay profile is then compared to a heat decay profile for a perfect sample of the same mobile phone 150. The heat decay profile indicates the wear of the external surface of the mobile phone 150, which is used in calculating the financial remuneration for the mobile phone 150.

Yet another method of the present invention comprises positioning an electronic device in an inspection area of a recycling kiosk 100, powering up the electronic device and displaying a known image on a LCD screen of the electronic device. The known image on the LCD screen of the electronic device is compared with a stored duplicate of the known image stored on the recycling kiosk to determine any defects in the LCD screen of the electronic device and to define an analyzed electronic device. The method further comprises determining a value for the analyzed electronic device.

In one embodiment of this method, the known image is a start-up image for the carrier of the electronic device. In an alternative embodiment, the known image is an image of a national park. The method may further comprise performing an electrical analysis of the electronic device.

The method preferably images the electronic device in whatever state the electronic device is in when the electronic device is placed into the kiosk. Then the method compares the images to the training database of all the different types of electronic devices that have been trained in the past (and all the trained images are preferably with their screens off).

The method preferably images more than the display screen of the electronic device. The method preferably images everything (some keyboards light up, on Blackberries for instance) on the electronic device.

The method preferably subtracts the analysis image from the first image. The method also preferably multiples the analysis image by a multiplier factor, to account for changes in the brightness of the screen. For instance, if the brightness of the screen does not change at all between the two images, the multiplier factor is 1. If the brightness of the screen was ½ as bright during the analysis image as during the “first image”, the analysis image is multiplied by 2 so that the brightness matches for better subtraction (basically there is a brightness compensation factor to account for screens that have auto-brightness that change when the dome light of the kiosk is on versus off). This image is the “synthesized” image, because the image is synthesized in part with the subtraction. The subtracted image is used synonymously with synthesized image.

The method preferably compares the subtracted image to all the different trained images of electronic devices, to first identify the electronic device, and then to analyze defects once the electronic device is identified. But the primary purpose of doing the subtraction is to generate an image of what the electronic device would look like if its screen was off, because it is preferred to compare that image to the trained images of electronic devices, which have their screens off, to identify the electronic device in the first place. Then, analyzing for defects comes after the electronic device is identified (or identified what it might be, which it might be a set of five or ten electronic devices that are similar).

Preferably, images are generated for the electronic device in the kiosk and compared to training data to identify the electronic device and determine the condition of all its features.

In another embodiment, there are two steps to processing: 1) obtain the silhouette images to determine where the electronic device is in the kiosk and the size of the electronic device (including the side view, the size of the sides of the electronic device, etc); 2) obtain the fully lit images and “map the texture” of the electronic device across the silhouette images to determine what the electronic device actually looks like when the electronic device is surrounded by light, instead of just the silhouette.

In one embodiment, the mirrors are only a small section of the walls of the chamber. Most of the walls are preferably white plastic/paint, made to diffuse the light to create uniform lighting, and minimize specular reflections.

In a preferred kiosk, five of the six faces of the electronic device are seen. The top camera sees the front of the electronic device and three of its sides (left, top, right), and the bottom camera sees the back of the electronic device. The part of the electronic device at the bottom (on an IPHONE phone, where the cable connector is) isn't visible because there only have three mirrors, not four. So the combination of both cameras sees five of the six sides, and the top camera only sees four of the six sides. The location, size, shape and color of all the buttons, regardless of the function, are imaged. For example, the IPHONE 4S mobile phonet looks identical to the VERIZON IPHONE 4 mobile phone, except that it has a SIM card slot on the side. So the kiosk 100 uses the presence of that SIM card slot to determine that the electronic device is an IPHONE 4S mobile phone, and not an VERIZON IPHONE 4 mobile phone.

The present invention preferably extracts features from the training images and stores them in a database, along with other information such as the make and model of the electronic device, the area/location of the screen, and other data.

The “perimeter image” is preferably not used to detect defects in the screen. The present invention analyzes the silhouette (area) of the image to help identify the device, because this silhouette provides the dimensions of the phone, and helps narrow down the devices in the training database to compare to (no sense comparing a big phone to all the small ones . . . just compare to other phones of a similar size).

FIG. 10 is an image of a mobile phone 150 with the lights on. The display screen 153 of the mobile phone is illuminated. Touchscreen buttons 153a-153c are visible. On the perimeter of the phone 150 physical buttons 156, 157 and 159 are visible. FIG. 11 is an image of the phone of FIG. 10 with the lights off. The display screen 153 is barely visible. FIG. 12 is a subtraction result of the image of the phone 150 with the lights on subtracted from an image of the phone 150 with the lights off. FIG. 13 is an image of a phone with the display screen 153 off. FIG. 14 is a line intensity profile of the image of FIG. 13 (solid line 1401) versus the image of the phone 150 of FIG. 12 (dashed line 1402). The spike at time 211 represents the text area in FIG. 12.

Another aspect of the present invention is detection of fake electronic devices. As shown in FIG. 15, an image of a lit unauthenticated mobile phone 150 (with the lights of the inspection area on) displays a picture printed on cardboard and placed underneath the display screen glass 153 in place of the LCD. The image has many colors and color variation on the screen area. However, the mobile phone is not emitting any light. When the lights of the inspection area are turned off, the display screen of the mobile phone 150 displays nothing as shown in FIG. 16. Thus, the kiosk 150 of the present invention can detect non-authenticated (counterfeit) electronic devices in an automated manner. Further, the image of a fake phone is stored in a database for training since the image is typically used multiple times. A fake phone also has no electronics in the housing. Thus, the mass of the phone would vary from an authentic phone so if the kiosk 100 was equipped with a weight scale another means of detection of fake phones would be possible.

Another aspect of the present invention is phone screen crack detection. As shown in FIG. 17, an image of an authenticated mobile phone 150 has cracks in the display screen 153. The present invention can distinguish between actual cracks in a display screen glass as compared to an image with many color variations by performing a color entropy metric since cracks in the glass will not give off multiple different colors.
