1. A dry powder inhaler, comprising:
- a vibrating mechanism;
a supply of a dry powder operatively coupled to the vibrating mechanism;
a power source in selective communication with the vibrating mechanism;
a sensor in communication with the vibrating mechanism, wherein the sensor is positioned to selectively measure a vibration of the vibrating mechanism when the power source is selectively removed from the vibrating mechanism;
a feedback control in communication with the sensor and the power source, whereby the feedback control controls power delivered to the vibrating mechanism; and
a frequency sweep generator connected between the power source and the vibrating mechanism for controlling a characteristic of power delivered to the vibrating mechanism.

Abstract
A dry inhaler system includes a vibrating mechanism. A supply of a dry powder is operatively coupled to the vibrating mechanism. A power source communicates with the vibrating mechanism. A sensor communicates with the vibrating mechanism. A feedback control communicates with the sensor and the power source. The feedback control controls power delivered to the vibrating mechanism relative to information provided by the sensor about the performance of the vibrating mechanism.
