  • Patent number: 10435567
    Abstract: Fluorinated and hydrogenated diamond-like carbon (“DLC-FH”) that have unique optical properties differ as a class from the existing DLC art, whose refractive indices [?]are limited to rather high values above a lower threshold of 1.7, and can range up to about 2.7. The DLC-FH materials can achieve very low refractive indices at 550 nm wavelength, [?550], i.e., below 1.5, and especially demonstrated down to 1.3. Moreover, whereas the absorption for the existing DLC art, as quantified by the extinction coefficient [?] at a wavelength of 550 nm, [?550] is limited to about 0.04, our DLC-FH material can achieve [?550] below 0.01. Both of these attributes, i.e., low [?550] and low [?550] means that, for the first time, a carbon-based material as represented by the DLC-FH material, can be used for anti-reflection (AR) coating, wherein there are no longer any restrictions in how they can be used to promote low reflectance (with low fit[?]) and high transmittance (with low [?]).

  • Patent number: 9795749
    Abstract: A dry powder inhaler includes a dose container assembly having a dose container disk with opposing upper and lower surfaces, a first row of circumferentially spaced apart dose containers at a first radius and a second row of circumferentially spaced apart dose containers at a second radius. The dose containers have dry powder therein and are sealed via a first flexible sealant over apertures in the upper surface and a second flexible sealant over apertures in the lower surface. A piercing mechanism includes two reciprocating piercers that serially alternate between the two rows of dose containers in the dose container disk. A rotatable ramp disk includes first and second sets of circumferentially spaced-apart ramp elements in staggered, concentric relationship that are configured to move the first and second piercing members between retracted and extended positions.
