Abstract: An XR display system includes a near-eye optical see-through XR display having an image presentation component with an eye-facing side and a world-facing side and configured to present virtual visual content to a user's eye from locations across an image presentation surface of the eye-facing side. A dynamic push lens positioned on the world-facing side and a dynamic pull lens positioned on the eye-facing side each include a liquid crystal cell dynamically switchable by an electrical stimulus between an inactive state and an active state. In the active state, the dynamic push lens converges environmental light approaching the image presentation component from the world-facing side by applying a positive optical power, and the dynamic pull lens diverges light passing out of the eye-facing side of the image presentation component toward the user's eye by applying a negative optical power.

Abstract: A system and method for capturing CO2 from air includes exposing the air to a source of water such that CO2 in the water is below equilibrium with CO2 in the air. The water may be enriched with hydroxides. In a preferred embodiment, the CO2 may be captured along with ammonia that is released from decomposing biomass using an apparatus including a first chamber receiving the water and a second chamber receiving the decomposing biomass. The first and second chambers are connected to allow transmission of air between the chambers while collectively defining an enclosed space from which air cannot escape. As the biomass decomposes, the enclosed air is enriched with CO2 and ammonia such that the CO2 in the water is below equilibrium with CO2 in the air so the water absorbs some of the CO2 in the air within the enclosed space.

Abstract: An apparatus for heating and agitating an irrigant inside a tooth's root canal includes a first portion and a second portion. The first portion is sized and configured to extend into the tooth's root canal via a hole in the tooth's dentin, and is operable to heat and physically agitate an irrigant disposed in a tooth's root canal. The second portion is sized and configured to move the first portion while the first portion extends into the tooth's root canal, and is operable to move the first portion in response to a driving force that the second portion receives. With the ability of the device's first portion to heat and agitate an antiseptic irrigant disposed inside a tooth's inner chamber, one can use the activator to simultaneously heat and agitate the irrigant.
