Abstract: Some embodiments include an assembly with an inlet housing enclosing an outlet housing that includes an inlet. The outlet housing includes an outlet port and a channel or aperture coupled to an outlet and apertures coupled to atmosphere. A moveable or flexible member is positioned in the inlet housing coupled to the outlet housing, and can deform, flex and/or move based on a flow and/or pressure of fluid from the inlet. Based on the flow and/or pressure of fluid from the inlet, the moveable or flexible member can reversibly move from a first position to a second position and/or from a second position to a first position. The first position is characterized by the moveable or flexible member being coupled to, proximate to, sealed to the aperture, and the second position is characterized by the moveable or flexible member being moved away from the aperture.

Abstract: Some embodiments include a fluid valve assembly with an outlet base dimensioned to be positioned through a drain in a fluid tank, and a float assembly including a moveable float.

Some embodiments include a housing positioned with the moveable float, where the housing encloses a suction device coupled to a moveable piston. Some embodiments include an actuable diaphragm positioned in the outlet base, and a compressed air tube or passageway coupled to one side the actuable diaphragm. In some embodiments, the actuable diaphragm is configured and arranged to be actuated by compressed air to move the moveable piston.

Abstract: A password management method employs one or more items from multiple categories of available information to enable user access to a secure resource. A user-specific strong password is generated. A neural network is trained to recall the strong password from the one or more items. Examples of such items may include a combination of letters, numbers, characters, and/or symbols, or pictures, in one category; information related to hardware used to access the secure resource, in another category; and a user's biometric information, in yet another category. Items may come from other categories as well. The neural network may reside on the hardware used to access the secure resource, or may reside at the secure resource itself, or in the cloud.

Abstract: Provided are negative electrode assemblies containing lithium sulfide anolyte layers, electrochemical cells including these assemblies, and methods of forming thereof. An anolyte layer may be disposed over a metal layer of a current collector and may be used to separate the current collector from the rest of the electrolyte. The metal layer may include copper or any other suitable metal that forms in situ a metal sulfide during fabrication of the electrode assembly. Specifically, a sulfur containing layer, such as a solid electrolyte, is formed on the metal layer. Sulfur from this layer reacts with the metal of the current collector and forms a metal sulfide layer. When lithium is later added to the metal sulfide layer, a lithium sulfide anolyte layer is formed while the metal layer is recovered. Most, if not all operations may, be performed in situ during fabrication of electrochemical cells.
