US Classification:

504206, 504234, 504250, 504324, 504358, 514788

Abstract:

Dual function viscoelastic surfactants (VES) which, when used in a pesticide formulation, are capable of producing a spray pattern between the patterns formed by spraying water and an aqueous pesticide solution containing guar gum as a way to reduce the drifting of the small drops to unintended targets while providing enhanced efficacy to the pesticide.

Appl. No.:

9/220780

Inventors:

Michael M. Walters - Raleigh NC
Charles E. Hawkes - Cary NC

Assignee:

Harris Corporation - Palm Bay FL

International Classification:

G05F 140

US Classification:

323282

Abstract:

A DC-to-DC power converter includes at least one power switch, a pulse width modulation circuit for generating control pulses for the at least one power switch, an output inductor connected to the at least one power switch, and a current sensor connected in parallel with the inductor for sensing current passing through the inductor. The current sensor preferably includes a resistor and a capacitor connected together in series. The current sensor is connected to a peak current control loop circuit cooperating with the pulse width modulation circuit for controlling the at least one power switch responsive to the current sensor. The resistor and capacitor preferably have respective values so that the current sensor is a substantially instantaneous current sensor. The output inductor has an inductance and a direct current (DC) resistance defining a first time constant. In one embodiment, the resistor and capacitor of the current sensor define a second time constant within a predetermined range of each other.
