  • Medicament delivery and packaging
    Publication number: 20050115562
    Abstract: A system is disclosed for the administration of a powdered medicament by inhalation. The system comprises a container (20, 60, 120) containing a unit dose of medicament in powder form, the container (20, 60, 120) having at least one dispensing aperture (21), and a device (10, 50, 100) having a chamber (19, 56, 110) adapted to receive said container (20, 60, 120). The device (10, 50, 100) further comprises air inlet means (12, 12a, 13, 13a, 112, 113) by which air may be drawn into the chamber (19, 56, 110) and means (11, 111) by which air and entrained medicament may be drawn out of the chamber (19, 56, 110). The system is arranged such that the container (20, 60, 120), in use, is stationary within the chamber (19, 56, 110).

  • Machine capability verification and diagnostics (CAP/DIA) system, method and computer program product
    Patent number: 6847908
    Abstract: A method for verifying the accuracy of a CNC machine or a CMM. The methodology segregates the measured error into an assignable cause portion and a common cause (or random error) portion. The methodology may be employed to affect the calibration of the machine tool to factor out the mean value of the assignable cause portion. Inherent in this methodology is the ability to diagnose mechanical problems with the CNC machine or CMM that affects the repeatability and accuracy of such machine tools; identify degradation in the performance of such machine tools that is indicative of mechanical failure; and improve the accuracy and repeatability of such machine tools in certain situations.
