  • Publication number: 20220271261
    Abstract: The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article.

  • Publication number: 20220230825
    Abstract: A method for performing a low energy pulse testing in a power distribution network that causes contacts to close and then open in about one fundamental frequency cycle of current flow time and close on a voltage waveform that produces symmetrical fault current. The method includes energizing a magnetic actuator to move the actuator against the bias of a spring to move a movable contact towards a fixed contact. The method also includes de-energizing the actuator when the movable contact makes contact with the fixed contact so as to allow the spring to move the movable contact away from the fixed contact so that the amount of time that the current conducts is about one fundamental frequency cycle of the current, where energizing the magnetic actuator occurs when an applied voltage on the switch assembly is at a peak of the voltage wave so that the current is symmetric.

The detachable containers can contain infusates or other solutes or materials such as disinfectants or cleaners, and can be conveniently seated in the infusate caddy. The detachable containers can be removed from the infusate caddy for restocking, cleaning, or resupply, as needed. The infusate caddy can be positioned or seated in a receiving compartment of a dialysis machine, and can also be removed, as needed. The fluid path and fluid connectors of the present invention provide the required fluid fittings, valve arrangements, pumps, and paddle assemblies for using the infusate caddy.

  • Publication number: 20210106763
    Abstract: An apparatus includes a first member and a second member. The first member is configured to receive a portion of a syringe barrel and includes a first stop surface. The second member includes a second stop surface. Each stop surface is configured to engage the portion of a plunger to thereby arrest longitudinal movement of the plunger relative to the syringe barrel. The second member is operable to move relative to the first member from a first position to a second position. The second member remains coupled with the first member while in both the first position and the second position. The second stop surface engages the portion of the plunger when the second member is in the first position. The second stop surface does not prevent the portion of the plunger from reaching the first stop surface when the second member is in the second position.

  • Publication number: 20210007890
    Abstract: An apparatus includes a body, a needle, a catheter, and an actuator assembly. The needle extends distally from the body. The needle has an inner wall defining a needle lumen. The needle lumen is in fluid communication with a fluid port of the body. The catheter is slidably disposed in the needle lumen. The catheter has a catheter lumen. The first actuator assembly is configured to translate the catheter within and relative to the needle. The apparatus may also include an actuator assembly that is configured to rotate the needle relative to the body. The apparatus may be used to first deliver a leading bleb of fluid to the subretinal space in a patient's eye via the needle.
