A new dry powder inhaler is developed as a pulmonary medicine delivery device for dispersing precise tiny dosages (10 μg-50 mg) of pure carrier-free ultra-fine powdered medicament (<5 μm aerodynamics particle size) into a patient's lung. The powder is drawn from the blister cell and dispersed through an outlet tube assisted by two air streams. The first air stream goes through a the blister cell from its upstream side, to significantly fluidize the medicament in the dose to flow upward. The second one extracts the fluidized powder from downstream of the blister cell for further deagglomeration and dispersion of the medicament powder by shear force. The rotating multi-dose blister can hold up to 60 doses, which are pre-metered with pure ultra-fine powdered medicament. So that it has higher drug loading capability in small volumes, compared to most current dry powder inhalers, which usually use some excipient. The inhaler efficiently disperse the aerosolized medicament in the air stream to the deep interior of patient's lung. The fine particle fraction (<4.7 μm) is reported to reach as high as 80% using this inhaler.

An innovative optical system and method is disclosed for analyzing and uniquely identifying high-order refractive indices samples in a diverse population of nearly identical samples. The system and method are particularly suitable for ultra-fine materials having similar color, shape and features which are difficult to identify through conventional chemical, physical, electrical or optical methods due to a lack of distinguishing features. The invention discloses a uniquely configured optical system which employs polarized sample light passing through a full wave compensation plate, a linear polarizer analyzer and a quarter wave retardation plate for producing vivid color bi-refringence pattern images which uniquely identify high-order refractive indices samples in a diverse population of nearly visually identical samples. The resultant patterns display very subtle differences between species which are frequently indiscernable by conventional microscopy methods. When these images are analyzed with a trainable with a statistical learning model, such as a soft-margin support vector machine with a Gaussian RBF kernel, good discrimination is obtained on a feature set extracted from Gabor wavelet transforms and color distribution angles of each image. By constraining the Gabor center frequencies to be low, the resulting system can attain classification accuracy in excess of 90% for vertically oriented images, and in excess of 80% for randomly oriented images.
