•  

  • Chief designer of a new RFID card reader that cost about one half the reader it replaced.  Developed a very low power radio frequency identification (RFID) card reading system.  The system was used as a replacement to hotel room door lock keys.  Received US patent #6,476,708.
     

  • Helped develop a wireless method to monitor the air pressure and temperature inside an automobile tire.  The system used a custom radio frequency identification (RFID) circuit.  A special antenna allowed an external magnetic excitation field to power the RFID circuit and retrieve the tire data.    Received US patent #7,019,711 (Coupled transponder and antenna system and method) and one Brazilian patent.
     

  • Helped develop a complete video interactive archery/firearm shooting range system.  System projected moving targets onto a fabric screen using a computer, laser disk player and video projector. Reflector tipped arrows and an infrared CCD camera determined where the arrows hit the target. Also developed a similar shooting range system that used infrared laser equipped pistols, rifles and shotguns. Systems launched laser light pulses at screen targets instead of arrows.500+ installations now installed and operating. Wrote detailed descriptions for a patent application on the techniques used. (Method and apparatus enabling archery practice)  Received US patent #5,566,951.
     

  • Conducted research and designed to detect, count and size air bubbles in blood using ultrasound techniques. Bubbles with volumes less than 1 nanoliter were detectable. Circuit used in a kidney dialysis machine. Designed and built a portable battery powered bubble monitor used by the company's sales force to show potential buyers the bubble-free nature of the disposable dialysis machine tubing sets. Wrote circuit descriptions for a patent application on the bubble detector system.  Received US patent #5,394,732, (Method and apparatus for ultrasonic detection of air bubbles)  Japan patent #2823513 and European patent
     

  • Developed a product that monitored the resistance of a domestic earth ground connection.  The circuit also measured the earth ground current and the voltage with respect to the power line neutral wire.  System was used in conjunction with a transient voltage suppression system.   Received US Patent 7,023,680 (Transient voltage protection and ground status monitoring apparatus and method)
     

  • Developed a system to monitor the concentration of a soap/water mixture used in carwash soap dispensing systems.  The method used an optical technique to maintain the desired soap concentration.  Wrote a description of the electronic circuit used in the monitor.  Over 3,000 systems were installed.  One patent pending.

  • Chief designer of a new RFID card reader that cost about one half the reader it replaced.  Developed a very low power radio frequency identification (RFID) card reading system.  The system was used as a replacement to hotel room door lock keys.  Received US patent # 6,476,708.  (Detection of an RFID device by an RF reader unit operating in a reduced power state)
     

  • Designed a system to flash large banks of conventional 40 watt fluorescent lamps synchronized to a CCD camera system.  UV light produced by the lamps allowed “glow-in-the-dark” makeup to be placed on the face and arms of actors. Movement of actors could then be recorded using the CCD cameras.   Systems are currently being used to produce animated movies.   Received US Patent #7,567,293
     

  •  Developed a system to monitor the concentration of a soap/water mixture used in carwash soap dispensing systems.  The method used an optical technique to maintain the desired soap concentration.  Wrote a description of the electronic circuit used in the monitor.  Over 3,000 systems were installed.   Received US Patent #7,300,197

• Published many articles and circuits in EDN, Electronic Design, Popular Electronics and Midnight Engineering magazines. Produced an extensive 10MB Internet web site that promotes consulting engineering services. The site also has a 250+ page e-zine of useful information on general science, technology, creativity, science experiments, inventing and electro optics.

• Developed several families of touch activated AC and DC electronic switches. Switches were mostly used to control lights, doors and intercoms in jail cells. Switches had to survive severe abuse without requiring replacement. Designed and developed a complete jail door control and monitoring system for Colorado Arapahoe County jail as well as several other jails in Texas, Florida, New York and California. Sent the line of products through CSA, CKC and UL safety testing programs. Developed another line of very low power DC capacitance proximity switches. One switch operates up to 5 years on a single 1.5v button battery.

• Designed, built and successfully demonstrated an optical through the air communications link with a range of 6 miles. Also demonstrated the feasibility of using clouds as large light pulse reflectors. In addition, conducted tests on atmospheric attenuation of light pulses under various weather conditions. Proposed methods for a 40 mile telemetry link using a xenon flash light source. Proposed uses for nitrogen spark light sources. Uses included optical radar and long range distance measurements. Proposed a wide area optical information broadcasting system that would cover an entire metropolitan area with high speed data services.

• Designed and developed several new consumer products, including cordless telephones, combustible gas detectors, smoke detectors, backup alarms, anti-carjacking alarms, coin operated panorama telescopes and motion intrusion alarms. The motion alarm worked on the basis of monitoring the disturbance of the earth's natural electric field. Wrote patent papers on the intrusion alarm system.
