Abstract: A poppet valve has an elongated stem that is configured to extend along a longitudinal axis. The poppet valve further includes a valve body that is disposed laterally with respect to the longitudinal axis and located in a spaced apart relation with an end of the elongated stem. The valve body has a pair of opposing faces disposed co-axial with the longitudinal axis of the elongated stem. The poppet valve also includes at least two arcuately shaped appendages depending downwardly from the end of the elongated stem and extending away from the longitudinal axis of the elongated stem. An end of each appendage is disposed in abutment with an annular region defined on one of the opposing faces of the valve body, a perimeter of the annular region being larger than a perimeter of the elongated stem measured about the longitudinal axis.

Abstract: A stacking portable water filter includes an upper and a lower canister, with the lower canister having a filter aperture which receives a filter cartridge therein. Untreated water received in the upper canister flows through the filter cartridge by gravity to be collected in the lower canister. Both canisters include an upper rim, with both upper rims having a substantially similar size and shape. A cover is also provided to fit on one or the other of the rims. In an operative positions with the containers stacked, the cover may mount to the upper rim of the upper canister. In a portable position with the upper canister removed from the lower canister, the cover may be mounted to the upper rim of the lower canister.

Abstract: The present invention provides a hybrid coupling structure of a short range surface plasmon polariton and a conventional dielectric waveguide, including a dielectric substrate layer, a dielectric waveguide layer positioned on the said dielectric substrate layer, a coupling matching layer positioned on the said dielectric waveguide layer and a short range surface plasmon waveguide portion, formed on the said coupling matching layer, for conducting the short range surface plasmon polariton. The present invention also provides a coupling structure of a long range surface plasmon polariton and a dielectric waveguide, including a dielectric substrate layer, a dielectric waveguide layer, a coupling matching layer and a long range surface plasmon waveguide portion upward from below respectively.

Abstract: A method for inputting passwords is provided. The method includes steps of: displaying a password inputting interface on a screen, wherein the password inputting interface displays a plurality of first objects and a plurality of second objects. The first objects each have different first identification features, such that a user can distinguish the different first objects through the first identification features, and the second objects are at different locations on the screen; receiving at least one of the first objects, followed by the moving of the received at least one first objects to at least one of the second objects, wherein the user operates the movement of the received at least one first objects; and determining if the operation is correct according to moving of the at least one first objects to the at least one second objects.
