Abstract: A extended reality communication system, methods, apparatus, and computer program product are disclosed. The communication system provides for remote real-time communication between a proctor and an operator, where the operator is performing tasks on a local work object, such as a patient. The system incorporates a combination of haptic, virtual keyboard, VR, XR, and audio inputs to provide communication of instructions between the proctor and the operator that are projected as a holographic image in a field of view on the patient. The system includes a proctor station and an operator station communicatively coupled with one or more servers.

Abstract: A diffusive air purifier includes an air permeable container containing a chemical sorbent or a sorbent precursor. The sorbent has a chemical composition selected to achieve removal of an air pollutant via a chemical reaction that renders the predetermined air pollutant immobile. A method of manufacturing the diffusive air purifier includes impregnating a porous solid with a solution of sorbent precursor and a binding agent and drying the porous solid. A method of purifying indoor air includes detecting a measured concentration of an airborne chemical in an enclosed location; selecting the diffusive air purifier to adsorb the airborne chemical; and placing the diffusive air purifier in the enclosed location. Air diffuses through the outer container and into the sorbent where the chemical to be removed is retained. Air, free of the target chemical, diffuses out of the container and the process repeats.

Abstract: Methods for fabricating functionalized substrate surfaces for use in preparing biomolecular microarrays, such that the substrate surfaces feature a uniform distribution of attachment functionality, functionalized substrates having such uniform distribution of attachment functionality, and microarrays prepared from such functionalized substrates. A plurality of linker groups are coupled to a substrate surface. A plurality of spacer groups including attachment sites for biological receptors are coupled to the linker groups. The linker groups can be coupled to the surface using a gas phase reaction. Spacers can include polyfunctional linear, branched or dendritic structures, such as polyethylene glycols and Starburst™ dendrimers. Attachment sites can be activated for the attachment of biological receptors.

Abstract: Methods, compositions and systems for processing biological samples include separation reagents featuring a microparticle and a receptor for a ligand on a target species in the biological sample. The biological sample is reacted with the separation reagent to capture the target species. A covalent bond is formed between the target species and the separation reagent to form an adduct. The adduct is separated from the biological sample, and a component of the target species is separated from the target species.

Abstract: The present invention comprises a safety apparatus which includes a means for covering a disconnect valve means and an urging means disposed near the covering means. The urging means urges the covering means to cover the disconnect valve means. The urging means further has a retraction mechanism for retracting the covering means from the disconnect valve means only when an external retracting command activates a retracting force on the retracting mechanism. Therefore, the valve is covered by the covering means and is prevented from being inadvertently operated during a system failure and an unsafe operation condition.
