Aurora Enterprises – Owner, Chief Engineer1997 – Present • Designed, developed and produced an RGB (red, green, blue) in-game LED meter for Bally Systems at Bally request. Performed all engineering design, PCB layout, debug and test of PCB’s and programming of basic functions. Designed and programmed (VHDL) Xilinx FPGA. Wrote firmware in C. Wrote drivers in C.• Manufactured and sold RGB in-game meter units to Bally on a sole-source supplier basis for about 7 years. Negotiated sole-source contract with Bally.• Designed a skill game for game room use in 16 states in the U.S. where casino gaming was not legalized. Invented and patented an algorithm for skill game pay and play that met existing legal criteria (U.S. Pat 7,192,346). Interfaced with State regulators. • Engineered and designed a bar-top slot in accordance with Pat 7,192,346. All security, game control and peripheral control features in a custom board designed in-house based on PIC32. Wrote firmware in C. Linux used as OS for video engine. • Game extremely economical to produce and had advanced security features.• Some games were formally approved by Eclipse Compliance Testing for use in Oklahoma. Eclipse certified game as being in compliance with U.S. Pat. 7,192,346.• Sample games developed on this platform may be seen at: http://www.pi-tronix.com/gallery.htm Or GoTo: http://www.google.com//#q=site:pi-tronix.com&, Then select Video Clips of Games. 15 August 2013 ceased development of skill slot.• Developed a robust identity/ loyalty card application for a slot which employed a contactless MIFARE card. Eliminated many problems with contact-type cards. • Acted as expert witness in 2 patent cases for Kirkland &Ellis.• Engineered a design for vehicle fueling system upgrade that provided distributed processing and Zigbee communications between modules. June 2013 to February 2014. Applied for provisional patent, transferred design to Poland.

Spintek International, Inc.2 years• Devised and patented, with another engineer, a considerably simpler approach than IGT virtual reel pay method to avoid conflict with IGT patent and allow very large jackpots to be awarded upon a spinning reel slot machine (U.S. Pat. 5,380,008). • Negotiated with investor and formed new company, Spintek, to develop, manufacture, and market slot machines to exploit aforesaid patent.• Worked with and directed mechanical engineer to design and manufacture a sheet metal spinning reel slot cabinet. Oversaw production of design for prototype.• Designed, engineered and produced a distributed architecture control unit for Spintek spinning reel slot. Pioneered use of smart distributed peripherals in the slot industry which allowed code and hardware modularity and simplified regulatory approval of new features. Modularity allowed cost savings and price reductions since a customer paid for only features he desired at the time and could add others later. • In charge of 4 engineers to bring project in on time and on budget. Attended exhibitions, interfaced with investors and demonstrated products to customers.• Engineered and programmed a walk-around data gathering system based on Dallas One-Wire system programmed in Windows and PowerBuilder for back-end. This gained considerable interest from many in the slot industry. • Founded Aurora Enterprises.

• With another person raised minimum seed capital to design, produce and market an incandescent-lighted linked progressive meter which employed a serial data link not commonly in use at the time. This greatly improved installation time, maintenance and reliability. One of first to use smart-peripherals in a system of this type. • P.I. Kaiser became one of two major players in the field. Negotiated partnership with Bally Gaming to provide link progressive meters domestically and internationally for about 8 years. This was of great financial importance to company since it now had backing from one of the only two major companies in the gaming industry at the time. • Designed and produced a retrofit board for Bally 1000 slots that significantly improved performance of that model. • Designed and implemented a walk-around data gathering system for Mills Jennings slots which employed an ultrasonic interface. Programmed a back-end PC based system to process data from said system.• Designed, engineered and prototyped a downhole recording water quality monitor. Presented this at a Western Water Quality Convention. Wrote firmware in machine code.• Engineered, prototyped, produced and sold a RGY (red, green, yellow) dot matrix linked progressive meter. Pioneered an extremely flexible sign enclosure construction method which allowed new shapes and much physically lighter sign enclosures to be constructed for indoor casino signs. Negotiated and procured a contract with IGT representative in Miami, FL to bid and build signage for many major cruise lines with gaming aboard.• Engineered, prototyped, manufactured and sold a slot machine retrofit kit which upgraded Bally electromechanical slots to a level of play that was not common at the time. Negotiated with Casino Purchasing Agent and sold retrofits in South Africa. Wrote firmware in C.

 Hired as consultant to evaluate and develop software drawing product Tapestron required to complete core product offering which was a carpet loom that printed carpets by means of selection of various yarn colors. • Oversaw, organized and specified development of a visual drawing program which allowed rapid artistic design and extraction of drawing data for Tapestron loom format. Given budget and authority to develop product by CEO.• Hired 4 programmers in Los Angeles and delivered product in a beta state in about 6 months time and on budget. Remotely managed development from Tennessee. • Completed contract and left to start up Spintek International.

• Product performed monitoring of leaks in underground fuel storage tanks, piping and fueling station piping to extremely tight EPA standards. • Proposed new system architecture to Mallory VP of Sales which was radically different and more efficient than anything in use in the industry. Engineered and developed the said system as chief engineer. • Designed and developed an ultrasonic intrinsically-safe level detector for underground fuel storage tanks that could detect a leak of less that 0.5 gal/hr (10,000 gal tank) tested by EPA and surpassed any future requirements proposed at that time. • Performed all hardware engineering design and aided in firmware design for the initial product. Participated in field performance tests and engineering presentations. Performed a key presentation for initial fundraising for D-Tech. • Engineered and prototyped a pollution detection buoy for lake and ocean deployment that could detect oil slicks on water and transmit an alarm. Product was prototyped for proof of concept, but never fielded. Wrote firmware in machine code.• Developed and prototyped a very reliable intrinsically safe detector for detecting presence of hydrocarbons on the surface of water. • Offered position by Tokheim in charge of D-tech engineering department after Tokheim acquisition of D-Tech. • Sought work as a consultant which was quickly found at Tapestron.
