Abstract: Provided are a detection substrate, a manufacturing method therefor and a flat panel detector. The detection substrate includes: a flexible substrate; a scintillator layer on a side of the flexible substrate, where the scintillator layer includes a central portion and a peripheral portion on at least one side of the central portion, the central portion and the peripheral portion are of an integrated structure, a thickness of the central portion at each position is approximately equal, and in a direction from an edge of the flexible substrate to a center of the flexible substrate, a thickness of the peripheral portion progressively increases; and a reinforcement structure, the reinforcement structure and the scintillator layer being on the same side of the flexible substrate, and the reinforcement structure at least covering part of the peripheral portion.

Abstract: A polarizer includes a light uniformizing structure. The light uniformizing structure includes a light-diffusion particle layer. The light-diffusion particle layer is configured to improve uniformity of light rays passing through the polarizer.

Abstract: A suction actuated valve, for a dry powder inhaler, includes a compressed air lumen; a control chamber for providing suction; and a trigger assembly having a displaceable membrane within the control chamber and configured to seal the control chamber such that suction displaces at least a portion of the displaceable membrane to provide an opening force to the trigger assembly for moving from a closed configuration to an open configuration. A trigger is coupled to the displaceable membrane and configured, in the closed configuration, to occlude the compressed air lumen and configured, in the open configuration, to open the compressed air lumen. The trigger has a first cross-sectional area and the displaceable membrane has a second cross-sectional area greater than the first cross-sectional area such that when suction is provided the displaceable membrane provides a mechanical advantage for moving the trigger from the closed configuration to the open configuration.

Abstract: The invention provides an inhaler for dispensing medicament. The inhaler comprises auxiliary energy provision means for providing auxiliary energy for aerosolizing medicament; energy release means for releasing auxiliary energy from the auxiliary energy provision means; feed means for feeding a dose of medicament, characterized in that the inhaler comprises control means for controlling a time interval between aerosolization of the medicament and a user's inhalation. The inhaler is operable, in use, to aerosolize medicament using the auxiliary energy, and harness the user's inhalation to deliver the aerosolized medicament to the user.
