    摘要: The present embodiments generally relate to enabling participants in an online gathering with networked audio to use a cancelling auralizer at their respective locations to create a common acoustic space or set of acoustic spaces shared among subgroups of participants. For example, there are a set of network connected nodes, and the nodes can contain speakers and microphones, as well as participants and node mixing-processing blocks. The node mixing-processing blocks generate and manipulate signals for playback over the node loudspeakers and for distribution to and from the network. This processing can include cancellation of loudspeaker signals from the microphone signals and auralization of signals according to control parameters that are developed locally and from the network. A network block can contain network routing and processing functions, including auralization, synthesis, and cancellation of audio signals, synthesis and processing of control parameters, and audio signal and control parameter routing.

    摘要: A method of producing a particle coating on one or more items is provided. The method comprises mixing supercritical carbon dioxide with a solution comprising dissolved material for forming particles. The method further comprises spraying the mixture into a precipitation chamber (316) to precipitate particles, wherein the chamber is at a pressure below a supercritical pressure of the supercritical fluid. The method also comprises capturing the precipitated particles on one or more items located within the chamber.

    摘要: An ostomy attachment comprises a flexible annular seal configured to embrace a stoma and a spout that in use is disposed beneath the stoma and configured to collect ostomy output at skin level and direct ostomy output away from the patient and annular seal and into an ostomy bag, in which the flexible annular seal is formed from an absorbent material and the spout is formed from a non-absorbent material. The annular seal may be an open ring comprising at least one mouldable arm that in use can be wrapped at least partially around the patients' stoma.

    摘要: An apparatus for the extracorporeal treatment of blood comprising an extracorporeal blood circuit (2), a pump (6) configured to provide fluid displacement within the extracorporeal blood circuit, and a reaction chamber (8) connected to the extracorporeal blood circuit and configured to receive blood or plasma from the circuit and treat the blood or plasma. The reaction chamber comprises a protease enzyme immobilized to a support, in which the protease enzyme is specific for, and capable of irreversibly cleaving, a human C5a present in the blood or plasma, wherein the abundance of the human C5a in the treated blood or plasma is less than that in the untreated blood or plasma. The apparatus finds utility in the extracorporeal treatment of blood from patients with inflammatory conditions, especially auto-immune disease and sepsis.
