Award List:

DIGITAL FLOW CONTROL FOR AUTOMATION OF PRECISION AGRICULTURAL SPRAYING

Award Year / Program / Phase: 1994 / SBIR / Phase I
Agency: USDA
Principal Investigator: Mr Graeme W Henderson
Award Amount: $50,000.00

DIGITAL FLOW CONTROL FOR AUTOMATION OF PRECISION AGRICULTURAL SPRAYING

Award Year / Program / Phase: 1995 / SBIR / Phase II
Agency: USDA
Principal Investigator: Mr Graeme W Henderson
Award Amount: $1,987,000.00
Abstract:
Inaccuracy in agricultural chemical application causes increased production costs and releases unnecessary pesticide and fertilizers into the environment. application control is primarily a manual operation and on-the-go adjustment of spray output for spray target or travel speed variation is rare.… More

PRECISE INJECTION OF NH3 USING PULSE-WIDTH MODULATION METERING

Award Year / Program / Phase: 1998 / SBIR / Phase I
Agency: USDA
Principal Investigator: Mr Graeme W Henderson , Principal Investigator
Award Amount: $64,001.00
Abstract:
Anhydrous ammonia (NH3), a heavily used nitrogen fertilizer, is a volatile gas which flashes at -40 F. It is handles as pressurized liquid and difficult to meter accurately and dispense. Its low cost, due to inexpensive energy, has encouraged wasteful over-application rather than investment in… More

PRECISE INJECTION OF NH3 USING PULSE-WIDTH MODULATION METERING

Award Year / Program / Phase: 1999 / SBIR / Phase II
Agency: USDA
Principal Investigator: Mr Graeme W Henderson , Principal Investigator
Award Amount: $220,000.00
Abstract:
Not Available Anhydrous ammonia (NH3), a heavily used nitrogen fertilizer, is a volatile gas which flashes at -40 F. It is handles as pressurized liquid and difficult to meter accurately and dispense. Its low cost, due to inexpensive energy, has encouraged wasteful over-application rather than… More

Flow Control and Operation Monitoring System for Individual Spray Nozzles

Award Year / Program / Phase: 2002 / SBIR / Phase I
Agency: USDA
Principal Investigator: Graeme W. Henderson
Award Amount: $80,000.00
Abstract:
This project addresses the increasing demands and need for precise control and reliability in agrochemical application. The ultimate goal of this project is a single-nozzle monitoring and control technology and device. The device will allow individual nozzle resolution on flow rate and spray droplet… More

Flow Control and Operation Monitoring System for Individual Spray Nozzles

Award Year / Program / Phase: 2003 / SBIR / Phase II
Agency: USDA
Principal Investigator: Graeme W. Henderson
Award Amount: $296,000.00
Abstract:
NON-TECHNICAL SUMMARY: Agricultural spray equipment operators typically cannot monitor all nozzles along the boom. Clogged or malfunctioning nozzles produce undesirable spraying results. This project is designed to lead directly to a useful product, namely, a single-nozzle monitoring unit for… More

Principal Investigator: Graeme W. Henderson
Award Amount: $0.00
Abstract:

Development of an integrated actuator for real time control of spray nozzle flow rate and droplet size spectrum

Award Year / Program / Phase: 2010 / SBIR / Phase I
Agency: USDA
Principal Investigator: Graeme W. Henderson, President
Award Amount: $90,000.00
Abstract:
Application of agrochemicals is essential to U.S. production of food, fiber, biofuels and ornamentals. However, it can also create environmental contamination if pesticides reach non-target areas through airborne displacement of spray, i.e., "spray drift". Drift is a concern for agriculture,… More

Development of an integrated actuator for real time control of spray nozzle flow rate and droplet size spectrum

Award Year / Program / Phase: 2011 / SBIR / Phase II
Agency: USDA
Principal Investigator: Graeme W. Henderson, President – 626-791-5911
Award Amount: $460,000.00
Abstract:
Typical agrochemical sprayers use nozzles to atomize a liquid stream into droplets; these droplets then travel to the target. Nozzles may be selected to provide a range of droplet sizes, spray distribution patterns, and flow rates for a desired liquid material application. Spray distribution,… More
