Apparatus for use in, or forming part of, a separation process to be implemented in separation processor technology, the apparatus comprising synthetic bubbles or beads configured with a polymer or polymer-based material functionalized to attach to a valuable material in a mixture so as to form an enriched synthetic bubbles or beads having the valuable material attached thereto, and also configured to be separated from the mixture based at least partly on a difference in a physical property between the enriched synthetic bubbles or beads having the valuable material attached thereto and the mixture.

A tubing set for a blood processing system includes a first connector, a first tube, and a second tube. The first connector is configured to connect to a separation device within the blood processing system, and has a first inlet configured to be fluidly connected to an outlet of the separation device. The first connector also has an outlet and a second inlet. The first tube fluidly connects to the outlet and fluidly connects the separation device and a blood component storage container. The second tube is fluidly connected to the second inlet and fluidly connects the separation device and a saline storage container. The second tube may include a second connector that connects to the saline storage container.

A filter membrane includes a membrane having through holes that selectively separates specific material in processing medium, the membrane including first, second and third layers such that the first layer has first surface that is supplied with processing medium, the third layer has second surface on the opposite side of the first surface, and the second layer is formed between the first and third layers. The first layer includes first convex and concave portions, the third layer includes second convex and concave portions each having a larger area than each first concave portion, the second convex portions are formed to surround the second concave portions and connected to one another, the second layer has through holes connecting the second concave portions and first set of the first concave portions, and the first concave portions include second set in regions opposing the second convex portions that is connected to each other.

According to an aspect of the present invention, it is possible to easily support a spark arrester and prevent an occurrence of damage or sound in the spark arrester due to the effect of an exhaust pressure or external vibration. In a spark arrester, at least a flange part is formed of a spring member. The flange part includes a bent part that is telescopically bent by elastic deformation in a direction along a flow of exhaust gas. The bent part is supported between a tail pipe and a muffler in a state where the elastic deformation of the bent part is allowed.

The invention relates to an air cleaner for a vehicle which can be installed on the rear of the vehicle, which includes a suction pipe provided with a slit having a length corresponding to a width of the vehicle, an air pump connected to inside of the suction pipe by a guide pipe, and a filter means connected to the air pump. The air cleaner is operated in a way of sucking exhaust gas and fine dust generated from an exhaust line of the vehicle together with fine dust and dust particles generated around tires of the vehicle during driving of the vehicle, removing them, and then discharging purified air to the atmosphere. The air cleaner can effectively remove the fine dust and various-shaped dust particles directly and indirectly generated from the vehicle, and remarkably reduce generation of fine dust by considerably suppressing diffusion of fine dust into atmosphere.

An apparatus for filtering a liquid includes a filter housing, at least one filter element arranged in the filter housing, and at least one sensor unit. The at least one sensor unit includes at least one sensor and a radio module. The at least one sensor is configured to detect an operating parameter representative of a state of at least the at least one filter element or the apparatus.

An entrainment-based filtering system for use in connection with a facemask or respirator that includes: a filter housing defining an interior volume comprising at least one airflow pathway having an airflow pathway length that is longer than the length of the interior volume and spaced within the interior volume; and a plurality of entrainment substrates. The plurality of entrainment substrates is positioned within the at least one airflow pathway and the plurality of substrates and the dimensions of the at least one airflow pathway together function to entrain particles on the surface of the chemically coated entrainment substrates and prevent at least 95% of particles traveling through the at least one airflow pathway from exiting the entrainment-based filter.

System and method to reduce risk of exposure to pathogens using a system comprising transportable clinical chambers, often configured with the exterior dimensions of a shipping container. The transportable chamber can be partially or completely self-contained, and configured for rapid transport and setup. The chamber is typically equipped with suitable automatic airborne sterilizing agent generators, sensors, mechanisms, and automatic air control devices. After suitable safety checks, the system isolates the interior air from external air, and activates an air phase anti-microbial agent generator, filling at least a portion of the chamber with an air-phase anti-pathogen agent. After sterilization, the invention deactivates the generator and then restores the connection to outside sterilized air. In some embodiments, the transportable chamber also comprises an intelligent platform comprising video cameras, and computer vision systems configured to identify humans and medical supplies, read optical tags, and correlate recognized objects with RFID tag data.

A turbomachine of the open rotor type or a turboprop engine comprises a nacelle defining an air inlet, a central hub and an annular air intake section surrounding the central hub and opening into a air supply main section, with the central hub comprising a central trap having an aperture for trapping the foreign objects in an air flow entering the turbomachine, and an air recovery channel having a discharge end, through which said air recovery channel opens into the main section, is provided on the central hub.
