Abstract
An electronically controlled micro-dispensing apparatus (10 or 210) is described. The apparatus includes a liquid storage container (12), a propellant container (16), a control circuit (34 or 42) and an ejector (28). In a second embodiment, the liquid and propellant are in the same container (212). The control circuits control the length of pulse and the time duration between each pulse. By controlling these factors, the apparatus dispenses a precise amount of liquid over a set time period. The ejector allows for controlled dispensing and allows the liquid to be sprayed a greater distance. In the preferred embodiment, the apparatus are used to dispense a pheromone in an outdoor setting, such as an orchard, to control insects.
