Abstract: Embodiments of the present disclosure may comprise a system for filling undercuts with an index-matching liquid on a wafer, the system comprising a plurality of edge couplers, each comprising an undercut and a waveguide. Embodiments may also comprise ribs that suspend the waveguide over the undercut. Embodiments may also comprise one or more main buckets and one or more monitor buckets. Embodiments may also comprise a duct that couples together the plurality of edge couplers, the one or more main buckets, and the one or more monitor buckets.

Abstract: A fluid dispenser including a fluid reservoir containing a supply of a fluid, and a fluid pump that is removably attached to the fluid reservoir. The fluid pump has a frangible sealing element and a pump engagement feature. The fluid reservoir has a reservoir engagement feature that is configured to engage with the pump engagement feature on application of a removal force, such that at least some of the removal force is transmitted to the frangible sealing element so as to cause the frangible sealing element to rupture. The fluid pump is configured to be removable from the fluid reservoir once the frangible sealing element has ruptured, without any portion of the fluid pump remaining in contact with the fluid reservoir post-removal. When the frangible sealing element is ruptured, the fluid pump inoperable.

Abstract: The present disclosure is directed to CoNiFe nanostructured catalysts, and the use of such catalysts in the electrochemical conversion of methane to methanol. In particular, the present disclosure is directed to nanocube catalysts having the formula Co1-xNixFe2O4.

Abstract: Various examples are directed to a measurement system for measuring an electrical property of skin comprising an excitation circuit, a receiver circuit, and a sequencer circuit. The excitation circuit may generate a periodic excitation signal that, when provided to the skin, generates a response signal in the skin indicative of the electrical property. The sequencer circuit may be configured to activate the excitation circuit to provide the excitation signal to the skin. While the excitation circuit is activated to provide the excitation signal to the skin, the sequencer circuit may activate the receiver circuit to execute a first sample cycle to generate a first plurality of samples of the response signal. A first value for the electrical property of the skin may be determined based at least in part on the first plurality of samples of the response signal.

Abstract: A valve assembly with a valve member coaxially received within a valve casing and interacts with the casing to provide a one-way inlet valve at one end of the valve casing and a one-way outlet valve at the other end of the casing with an annular compartment therebetween adapted to be coupled to a variable volume compartment and thereby together provide a simplified construction for valving components of a fluid pump.

Abstract: A piston pump assembly in which a piston-forming element to be received in a piston chamber of a piston chamber-forming member carries a removable stop flange member which may be secured to the piston chamber-forming member to provide a retention stop to prevent the piston-forming element from being removed from the piston chamber.

Abstract: A piston pump which permits advantageous operation over both short stroke piston movement and long stroke piston movement.

Abstract: A piston pump dispenser having a reciprocating piston pump arrangement which in a dispensing stroke dispenses fluid from an outlet and in a charging stroke draws fluid from a reservoir and also draws back fluid from the outlet.

Abstract: The present invention provides a piston pump for liquid in which a sump is defined in a chamber into which sump liquid in the chamber flows due to gravity. A passageway leads from an outlet of the sump out of the chamber to a dispensing outlet. The dispensing outlet is at a height below the height of the sump outlet and fluid to exit the sump flows from the sump outlet upwardly in a first portion of the passageway to a height above the sump outlet then downwardly to the dispensing outlet. The chamber and its sump is defined between a piston chamber-forming member defining the chamber to be downwardly opening and a piston forming element axially slidable in the chamber.

Abstract: An improved arrangement for removably coupling a replaceable cartridge to a housing of a dispenser with the cartridge including a resilient member which prevents radial movement relative a catch member of the housing from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration.

Abstract: An improved arrangement for removably coupling a movable element of a piston pump to an actuator mechanism with the movable element including a resilient member which prevents radial movement of the movable element relative a catch member of the actuator mechanism from a coupled orientation unless the resilient member is deflected from an unbiased inherent configuration.
