 Retrofit existing vending machines with:  New interactive features  Energy saving technology  Globally accessible inventory control system  Extremely Modular Upgrading System  Allows for customizable module additions depending on owner needs

 User interface replaced with LCD touch screen display  Upgrade to electronic payment technology  Upgrade to high-efficiency lighting  Conserves energy by hibernating when there is no human interaction  Wired/wireless host interface

 Altera Cyclone II FPGA  Handles  LCD Touch Screen Driving  Motor Driving  Vending State Machine  NIOS II soft-core processor  Handles  Payments  Host Communication  Sensors  LCD Graphics Processing  Replace existing control board  Emulates current vending machine functions  Implements new upgraded features

 High resolution Touch Panel LCD  8bit per color  Displays user interface and information  Dynamic Menu Selection  Replaces keypad  Electronic Payment interface  Authorized Payment

 Utilize existing bill and coin acceptors  Multi-Drop Bus (MDB)  Standard for coin/bill acceptor communications  Proprietary current-controlled signal  Not trivial to convert MDB to any standardized protocol  MDB2PC ™ board  Hardware/Software interface for MDB to RS232 conversion  Allows controller board to communicate with coin/bill acceptor and process payments/payouts  Board donated by Upstate Networks

 Magnetic card reader and RFID  Credit/Debit cards  Buff OneCards  Identifications cards  Reloadable charge card  Allows for loading credits on any card with a magnetic stripe or RFID.  Interface with control board via RS232 for processing

 VeriVend System  Optical sensor detects if item has dropped  Motion Sensor  Detects human presence, and brings the system out of hibernation  Temperature  Monitor temperature of Soft Drinks/Snacks  Alerts host of temperature issues  Tilt/Shock Sensor  Detect if someone tilts machine  Set off alarm  Alerts host of attempted mischief

 Utilize existing motors  Modify hardware to drive motors  Motors are wired in a matrix configuration  Motor high and motor low signals are multiplexed to rows and columns to select a single motor  Motor Driving:  500mA (including in-rush current)  Motors run one at a time  Operates at infrequent intervals, so power dissipation is not a problem

 Currently uses Fluorescent Lighting  Replace with LEDs  Hibernation mode  Goes into hibernation mode with no human interaction  LED lighting and LCD will turn off  Light-sensing control  If not in hibernation, lighting adjusts with light intensity

 Uses a wired or wireless connection  Wired:  RS232, Ethernet  Wireless:  Zigbee, Bluetooth, or WiFi  Features  GUI on a Windows Host PC  Inventory Control  Pricing  Sales/Profit  Service Mode
