## Title
Vending machines with lighting interactivity and item-based lighting systems for retail display and automated retail stores

## Abstract

Vending machines, automated retail stores, and retail displays with computer controlled, item-based lighting that produces variable visual effects in conjunction with actual or potential vends to provide an enhanced vending experience. Offered products are stored within display tubes that are arranged in orderly geometric arrays. RGB lighting through a plurality of LED banks within polygonal circuit boards associate with each display tube are controlled by a computer activation system that senses the presence of a customer, and the selection of a vend. Combinations of differently colored LED's are computer controlled on a per product basis to artistically illuminate available products and assist customers. Pre-programmed lighting sequences can switch LED off and on, vary their intensity, and alter resultant colors. A touch screen computer responds to user inputs for selections and transactions. Sensors detect the presence of potential customers, even without a customer input, to vary a display and attract mode.

No. 61/106,952, filed Oct. 20, 2008, and entitled “Lighting Interactivity And Item-Based Lighting Systems In Retail Display, Automated Retail Stores And Vending Machines,” by inventors Mara Segal, Darrell Mockus and Russell Greenberg, and priority based on said application is claimed.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to automated vending machines. More particularly, the present invention relates to smart, computer controlled interactive vending machines equipped with enhanced lighting and display systems for producing a variety of visual effects in conjunction with vends or potential vends in conjunction with automated retail and or interactive retail deployments and retail displays.
2. Description of the Related Art
Numerous prior art vending machines exist for selling or vending diverse products through an automated, or ‘self-service’ format. Vending reached popularity in the late 1800's with coin-operated devices dispensing diverse merchandise. More recently vending machines have evolved to include robotic dispensing components, and/or PCs and virtual interfaces. These new vending platforms have emerged in the marketplace under the popular descriptions “automated retail,” “interactive retail,” and/or “interactive retail displays.” Such vending machines may be deployed within a variety of retail or commercial settings. They typically include illuminated, visual displays that seek to attract and educate customers or potential customers. Products information may be customer-requested utilizing interactive displays, including touch screen computer interfaces and virtual interfaces. However, a disadvantage of known machines relates to their cumbersome and “mechanical” appearance.
Automated retail stores, vending machines, and/or retail display platforms still look and feel like large, unfriendly machines or “mechanical boxes.” Such machines provide potential customers with a cold, impersonal and indifferent impression, which is not conducive to maximizing sales. Such prior art vending machines lack the sophistication of traditional retail stores in both the end user and retail display experience. This is due to the standard lighting, interfaces, and display mechanisms within these platforms. Displays are limited in the amount of information that can be communicated about a product. They are limited by space constraints. Further, they fail to provide the depth of information found in many e-commerce portals. Additionally, information on products within traditional automated retail/vending platforms has historically been limited to either the virtual touch screen or the physical display and there is no perceptual link between touch screen information and products being displayed beyond digital images on the touch screen.
Typically, the presentation of merchandise and information offered by traditional vending machines has not evolved sufficiently to satisfy a discerning consumer of premium or upscale products. Thus, the lack of a premium design or appearance has proven to be a hurdle for the distribution of expensive luxury items in automated vending machines.
In addition, default methods for lighting vending machines and automated retail stores are also utilitarian and dated. The default method of lighting in vending machines has been a fluorescent tube system which may either backlight or peripherally light the products, buttons, or displays. This method is less energy efficient, requires frequent changing of lights, is limited in functionality, and casts the same quality of light across all vending products. Fluorescent lighting also has hazardous consequences for the environment.
It is thus desirable to provide an enhanced vending experience or ambience in conjunction with the vending of upscale products. To increase the attractiveness of an upscale vending machine, it is desirable to provide an enhanced LED (light emitting diode) lighting system that can be individually controlled on a per product basis to more artistically illuminate available products, to guide users towards specific products, to draw users in to the machine, to indicate certain user inputs, to delight users during the shopping process, and to maximize the ambience associated with the transaction. It is further desirable for an ideal upscale vending machine to interactively guide user inputs, to indicate product recommendations and selections, and to elevate the merchandising experience achieved through an automated vending platform to approximate that of a luxury or specialty store.
BRIEF SUMMARY OF THE INVENTION
This invention provides an enhanced, customer interactive vending machine ideal for upscale products for use within an automated retail store or commercial environment. Importantly, the instant vending machine utilizes enhanced lighting that can be individually controlled on a per product basis to better light and display products and interact with the customer
This invention uses LED lights on controllers with the capability to shape the quality, intensity, and color of light on a granular/per product basis through placement and software programming that integrates lighting changes with diverse sensor inputs including motion sensors, pressure profile sensors, and touch screen selections inputted by users. The preferred system works on an individual product basis to both enhance the lighting on a product and facilitate user interaction. This invention also uses a virtual network by which software that controls the LED controllers and lighting experience can be updated remotely without visiting the individual store or changing the bulbs and fixtures. The invention includes programmable LED lighting, sensors that detect motion through touch and human gesture, and software that integrates the functionality of these components that can be updated through a remote/virtual network.
The lighting system facilitates choreography of light events to user presence and responds to user inputs to guide the user through selections and transactions. It also performs ‘passive’ lighting events in a “display and attract.” Lights may be switched on or off through varying sequences, light intensity and directionality may be varied, and assorted color combinations may be displayed to engage passerby's. This lighting system can be integrated with audio systems and additional display components through software. By virtue of this invention, lighting is also able to be custom designed on a per product basis with individual display units that comprise a greater merchandising display of several individually illuminated products. Lights are controlled on the basis of intensity and color balance to best enhance the product for easier viewing and more attractive display.
The enhanced functionality, flexibility, and control of the preferred lighting system allows for superior merchandising, efficiency and ease of the user experience, greater energy efficiency, and cost savings in terms of labor to replace lighting that does not have efficiency of LEDs. In addition, the LED system can be adjusted to harmonize with the ambient light quality of the room. In a dimmer environment, like in a hotel lobby or spa, the base level of brightness to the machine will be set lower than if the machine is placed in a very well lit environment, such as a department store. In conclusion, as far as we are aware, no lighting system of flexible LEDs and integration of LEDS onto a virtual network within an automated retail store, vending machine, or retail display exists for ease of customization, configuration, intuitive interfacing, utilization and low-cost of maintenance of this system.
Preferably a plurality of RGB (red, green, blue) and white LEDs provide programmable, highly customizable lighting that responds to sensors and software for a unique visual experience. Various LEDs are disposed on controllers within an architectural system of boards that fit display custom modules. An additional system of sensors (motion detectors, touch and pressure point) is programmed to interface with the lighting through software that controls the lighting. A touch screen which deploys information also interfaces with the lighting through the software. This software is able to be updated over a virtual network enabling quick adaptation to lighting events for multiple stores and removing visits to individual displays for adaptations. The sensors tell the software when a user is interfacing with the display (a product or products), and/or approaching the store (either passive or active engagement).
Touching the display activates a lighting event through a pressure-based profile sensor which triggers LEDs to brighten, or dim, change color, or turn on/off. During a passive state, the LED system is able to produce lighting sequences (shows) that are pre-programmed and involve LED lighting turning on/off, increasing in intensity, and/or altering in color based on a design that has been set in a configuration file and read real-time by the software.
Beyond approaching the automated store and LED lighting correspondingly responding through a state change, or by a user touching a plane in front of a product to indicate a selection and lighting correspondingly responding through a state change, lighting is also programmed to respond to state changes in the automated store (entering into a passive mode, or indicating lack of inventory) through a state change in lighting. In addition, LED lighting within the display also responds to inputs that the user makes within the touch screen portion of the display (a separate, but integrated monitor that contains digital information that the consumer interfaces with to operate the machine or engage with promotional content). Through selections and operations performed on this touch screen corresponding LED lighting events occur within the display—example, if a product is selected for purchase, the product module in the display will brighten and/or change color.
Examples of LED lighting state changes include: if a product is being dispensed by the robotic arm (or when a mechanical component is working), the lighting can blink. If a user is being prompted to swipe a credit card, LED lighting around the base of the card slot can blink. If the robot is dispensing a product, the product retrieval area will become illuminated when the product is in place for retrieval. If a product recommendation is being made based on inputs that the user has made, or information that has been stored about the user from prior use sessions, lighting may indicate a recommended product through brightening, dimming, blinking, or changing in color. If a product is indicated to be ‘out of stock’ frontal lighting in the module can dim, or turn off completely. The system of sensors and lighting in the interactive retail display/vending platform allows a user to seamlessly select a product by physically touching a display ‘unit’ on the frontal plane of this unit (a system of which comprises the façade of the store/sign/display). The lighting of this ‘unit’ brightens as the user's hand or body part approaches it and the ‘unit’ becomes highlighted when touched to indicate that a product has been selected or interfaced with. In other words, users may directly touch the display to select an item for dispersion and presentation on the touch screen where the transaction may be completed.
Touching the display or touch screen can also perform other actions, including the retrieval of additional information about the product including product recommendations. Several advantages occur. A user experience results which is more intuitive and interactive and hence more engaging than that experienced with ordinary machines. A more efficient lighting system with lower maintenance requirements and remote maintenance capabilities minimizes required service. The merchandising display can more attractively and precisely light individual products. The remotely customizable and individually configured LED vending machine lighting system increases the machine attractiveness. An intuitive way is provided to indicate when a product is “out of stock” without empty store shelves, which ordinarily tarnishes the store experience. An intuitive grouping method is provided to tie similar products together, to make sure the range of available products that a customer might be seeking is made known.
Thus a basic object of our invention is to provide a simpler, more intuitive, efficient and entertaining method of selecting a product, or multiple products, with an automated vending machine.
Another important object is to provide an interactive retail display in the form of a vending machine that uses interactive lighting and produces variable lighting effects in response to user inputs.
Other objects are as follows:
a) to provide a method for guiding the selection of a product with a user's hand or body motion.
b) to provide a method for triggering lighting events and/or promotional events in an automated retail store, vending machine, or retail display to attract the attention of passerby's.

FIG. 4A a typical LED light circuit board 400 similar to circuit boards 101 and/or 301 is detailed. The circuit LED board is designed in such a way that can be used as part of a series of lights that cover a predesigned display area. The board can be cut in any shape and assembled into any pattern as determined by the product display area. In the preferred example, boards 400 can be cut in an octagonal fashion. This shape allows them to properly illuminate circle display areas. Diamond cut boards 440 (FIG. 4C) can be used in conjunction with these to create a circle and diamond display motif.
A plurality of boards 400 form an array such as array 300, and are interconnected. The front side of each board 400 contains one or more sets of three LED lights, providing a red, green and blue light sources. Wiring connections 405 connect with a plurality RGB LED lights mounted on the front side of the board 400. A wiring connection 401 connects to white “showcase” lighting on an adjacent board in an array, such as array 300 (FIG. 3). A wiring connection 402 is for an adjacent LED board containing a plurality of Red, Green and Blue LED lights such a square or diamond shaped backlight board as the display area warrants.
A wiring connection 403 couples to a white showcase light working in concert with the current LED backlight board 400. Wiring connection 404 couples to another showcase light for the current LED board to provide stereo front lighting. Power connection 406 powers an LED backlight board consisting of a plurality of RGB LED lights, one or more front showcase white lights, and an adjacent backlight board consisting of a plurality of RGB LED lights and one or more front white showcase lights for that adjacent board. Connection 407 enables an RS-485 connection to the board's components. Recommended Standard 485, also known as EIA-485, is a standard for serial binary data signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment).

Touch sensor inputs arrive through interconnection 482. Cooling fans are controlled through cabling 483. Motion sensor inputs from a motion sensor such as Digi's Watchport/D (part number Watchport/D 301-1146-01) are received through connection 484. Cabling connections 483 and 484 are shielded as indicated by reference numeral 485. The touch system is connected to the computer 450 via cabling 486.
FIG. 6 illustrates a more detailed alternative power distribution arrangement 500. Because of the various components needed in the system, power has to be converted to different voltages and currents throughout the entire system. The system is wired so that it can run from standard 110 V.A.C. power used in North America. It can be converted to run from 220 V.A.C. for deployments where necessary. Power supplied through plug 452 powers an outlet 453 (FIGS. 5, 6) that power UPS 454 that conditions source power, which is applied to input 455 via line 456. Power is available to accessories through outlet 453 and UPS 454. An additional AC outlet strip 501 such as Triplite's 6 position power strip (part number TLM606NC) powers LED lighting circuits 502 and a touch system 503.
A 24V DC Power Supply Open Frame 24VDC, 6.3 A, 150W power supply 505 powers Y controller 506 such as the Arcus Advanced Motion Driver+Controller USB/RS485 (part number Arcus ACE-SDE), that connects to Y axis stepper 507 such as the Moons stepper motor (part number Moons P/N 24HS5403-01N) and X controller 508 such as the Arcus Advanced Motion Driver+Controller USB/RS485 (part number Arcus ACE-SDE), that connects to X axis stepper such as the Moons stepper motor (part number Moons P/N 24HS5403-01N). Power supply 505 also powers dispenser controller 510, dispenser door control 511, and vending controller 512 that respectively powers two gantry motors 513 and 2 conveyor motors 514 such as Canon DC gear motors (part number 05S026-DG16), door stepper motor 515 such as a Canon DC gear motor (part number 05S026-DG16), and spiral motors 516 such as the Vendapin Universal 24 volt DC gear motor (part number 605008-001). The logo space 201 (FIG. 2) is illuminated by lighting 518 (FIG. 6) powered by supply 505. Supply 505 also powers LCD touch screen block 520 (FIG. 6) such as a Ceronix 22′′ Widescreen (16:10) Touch Monitor. UPS 454 (FIG. 6) also powers an AC outlet strip 522 that in turn powers a receipt printer power supply 523 such as Epson's 24VDC power supply (partn number PS-180) that energizes receipt printer 524 such as Epson's EU-T300 Thermal Printer, an audio power supply that powers audio amplifier 527 such a Happ Controls Kiosk 2-Channel Amplifier with enclosure (part number 49-5140-100), and a low voltage cell modem power supply 530 that runs cellular modem 531 such as Multitech's Verizon CDMA cellular modem (part number MTCBA-C-IP-N3-NAM).
Lighting wiring 600 is detailed in FIG. 7. A/C inputted at 602, 603 and 604 respectively powers a 12V DC Power Supply Open Frame, 12.5 A, 150W 605 such as Lambda's power switch (part number SWS150-12), and two 24V DC Power Supplies (24VDC, 6.3 A, 150W) 606, 607 such as those by Lambda (part number SWS150-24). Power switch 605 supplies 5 volt power on cable 611. Power switches 606 and 607 supply 24 volt power on cables 613 and 612 respectively. One 5 volt power wire and two 24 volt power wires are connected on a multi-wire cable in connectors 608, 609 and 610. From there, multiwire cables 615, 616 and 617 carry the 5 volt power and two 24 power wires to each LED board. The two 24 volt wires power the lights and the 5 volt wire is fused or the logic on the LED board 400. Items 608, 609, and 610 respectively connect to daisy-chained subarrays 615, 616, and 617 of LEDS (FIG. 7). Logo lighting at 619 is also powered by item 608.
The LED subarrays 615-617 are daisy chained and connected to DMX controller 622 such as ENTTEC DMX USB Pro 512 I/F Controller, outputting digital signals on line 621 DMX controller 622 is connected via a USB connection to the computer 450 (FIG. 5). DMX controller 622 connects to the first LED board in the daisy chain. Each board is linked together in a series in this fashion with an input and an output signaling cable. There can be any number of LED boards as needed to fit the display deployment. The last LED board in the series is typically the light used for a logo or branding signage. Alternatively, this can be the first board in the series or in between two sets of LED display boards. Additional lights to illuminate an optional product collection area in a vending unit and lights to illuminate advertising signage can also be hooked up to this series of lights. Power comes from a standard alternating current outside source such as an electrical outlet. This power is converted as necessary to power the LED lights according to the LED specifications. Different types of LEDs can be used in any implementation and the power converters will change accordingly.
FIG. 8 details the lighting element connections. In a preferred implementation of the LED lighting system, each LED circuit board 809 (similar to boards 101 in FIG. 1) controls the RGB backlights on the current board, front white showcase lights such as Cree XLamp® 7090 XRE (part number L1-WN-P4-0-01) 805 and/or 806 for the current display area and the RGB backlight board 803 in a smaller display tube, and white front lights 804 such as Cree XLamp® 7090 XRE (part number L1-WN-P4-0-01) for the adjacent board. Each one of these configurations is hooked up in a daisy chain series. The board receives a communication signal from the previous board 807 and then passes that signal onto the next board at 802. The power is also passed in and out of each board 801. The address of the current board is set through a 6 wire set 808. Connected to exposed pins 821, 822, 823, 824, 825, and 826. Pin number one 821 carries 24 volts. Pin number two 822 is a ground. Pin number three 823 carries 24 volts. Pin number four 824 is a ground. Pin number five 825 is a ground. Pin number six 826 carries 5 volts and is used to power the PCBA 809. A terminator is put on the last board in the chain.
In FIG. 9 lighting is wired to accommodate illuminated signage and lighting for the area where a user collects a purchased item. 24 volt and 5 volt power at input 902 and a signal at 903 are supplied to the signage board 901. Connections on this board can be used to power and control one or more white LEDs 904 such as Cree XLamp® 7090 XRE (part number L1-WN-P4-0-01) that can be placed in a product collection area and lit to guide a user and illuminate a purchased product/item. A connection is supplied 905 to attach an additional optional LED RGB backlight board and a connection 906 to attach an optional white LED light such as Cree XLamp® 7090 XRE (part number L1-WN-P4-0-01) to enhance existing signage or for additional signage lighting.
In FIG. 10 lighting series wiring is disclosed. Any number of lights can be connected in a daisy chain series to light up product display, signage and user interaction areas such as bins to collect products, near controls that user's need to use, etc. At the beginning of a chain is a DMX controller 1002 that is connected to a CPU and a power connection 1005. The DMX controller communicates with one or more main LED boards 1001. These can be optionally connected to smaller supplementary LED boards 1003 of various shapes. This arrangement allows efficient coverage's of a display area. These groups of lights can be connected in series 1004 using RS485 signaling to create any display area shape.
FIG. 11 illustrates a general software implemented lighting process 1100. The system uses a set of customizable lighting events that are programmed as a set of data stored in either a database or flat file storage system that are called by the software based on user interaction. User interaction determines which item(s) are to be lit. There is a data store that maps items to the physical lights. This is set during the configuration setup and called at runtime. Each lighting event contains information on which light(s) to display, color of background, intensity, fade timing, foreground lighting (showcase lighting). This information can be dynamically passed in to the lighting event routine using the lighting event data template to guide the outcome. There is no limit on the number of “events” that are stored and triggered by the software. After an event is programmed in the software, the characteristics of that lighting event can be customized through data entry. This does not require the software to be reprogrammed or recompiled. The software reads the data in the data field at runtime and executes according to the values stored. This has a great advantage in that non-technical people can define how the lighting events behave without the need of a trained professional such as a computer programmer or a computer scientist or computer engineer.
User input step 1101 is queried at step 1102 to determine whether a lighting event has been selected. If not, the process ends at 1103, and if so, the type of event is determined in steps 1104 and 1105. An item ID and light mapping datacode are developed in step 1106. Selected lighting event characteristics are looked up and determined in step via database query step 1108. The identified lighting event is converted to the DMX protocol in step 1109. The DMX controller executes the lighting event and the hardware of FIGS. 7-10 responds. If an error is determined in step 1112, a light reset command is generated in step 1114 that resets step 1109.
User lighting software steps are detailed in process 1200 (FIG. 12.) Program 1200 begins (after power up and initiation) with a user input. A user starts the process when they interact with the machine in a detectable way. This may be by using the touch screen in step 1021, touching an activated touch sensitive façade area in step 1202, or triggering a sensor such as a motion sensor, magnetic field sensor or a weight sensor connected to the machine in step 1203. Each of these cause an event to be recognized that was pre-programmed to use dynamic variables generated by the user and apply them to the lighting rules preconfigured by an administrative user. After the user triggers the machine, they may browse products in step 1204, go into a rapid shopping mode (here described as Grab and Go mode) in step 1205. When a user elects step 1205, he or she can select products in step 1207 which triggers selectively variable lighting through the previously described software and hardware. When checkout is selected, the checkout process step 1208 determines payment success, and dispensing occurs in step 1210. Errors are detected in step 1212, and if possible, corrections information is delivered for retry to step 1210. If the product cannot be vended, an error display occur in step 1214 and the customer is credited in step 1215. If the vend occurs, the user is prompted to physically pick up the product in step 1216 and a “thank you” message is initiated by step 1217.
If users select the “browse” option in step 1220 similar products available for vending are determined in step 1221 and such similar products are illuminated via step 1222. Top picks can be selected in step 1223. Products are added to a “shopping cart” in step 1225, which then triggers step 1208 previously described.
Thus software process 1200 allows users to typically use the system to navigate to items/products in which they are interested and choose to add ones they wish to purchase to a virtual shopping bag. When users are navigating the products, the system is programmed to recognize the current event and initiate a lighting sequence. A user viewing a product on the touch screen will have the physical product (or representation of that product) illuminate in the display case according to preset values that determine the backlight lighting color, intensity of that backlight color, fading and lighting patterns such as color transitions, blinking and other light oscillations along with the intensity of front showcase lighting that shines on the front area of a product or item. Product/item associations can also be programmed into the system. For example, the product database stores various associates a product may have such as type of product, manufacturer of product, price range, special or sales pricing. The number of associations a product might have is infinite and determined only by the administrator that sets up a given product catalog. The lighting system can be programmed to use any of these associations and light up the areas in the display façade with a related association. These lighting scenarios assist the user in finding the products they wish to purchase and may increase the number of items that are sold to that user. After the user locates the products they wish to purchase and add them to their virtual shopping bag, they can initiate the checkout sequence. The lighting system recognizes this event and will use the items the user has selected as dynamic variables that it feeds into the event profile preprogrammed for this lighting event. A common example might be that all of the items a user is purchasing are illuminated with a given color in the display area and may blink or have the color oscillate to indicate to the user what items they are purchasing. Lights may be located on the machine that guide the user to controls in which they need to interact with to complete the process. For example, a light near the payment read (e.g. a credit card reader) can be illuminated when it is time for a user to swipe and have their credit card read. This simplifies the buying process by prompting the user what they next step in the process is. Dispensing products is another recognizable event where the system can be programmed to use lighting to indicate what product is being dispensed at the current time. As products are dispensed, the lighting can be programmed to change so the user knows which items have been dispensed and which items have to be dispensed.
After items are dispensed, a collection event is launched where the collection area can be illuminated to guide the user where to retrieve their products and provide lighting so they can more easily be seen. The system resets itself to a standby lighting event after a transaction is complete. The system can also be programmed to go into an idle mode after a preset amount of time. This idle mode lighting event sequence is often used to attract users to the system where the process begins again.
From the foregoing, it will be seen that this invention is one well adapted to obtain all the ends and objects herein set forth, together with other advantages which are inherent to the structure.
It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of the claims.
As many possible embodiments may be made of the invention without departing from the scope thereof, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
