A chair for particular use in clinical or hospital environments has a frame to which a support material is secured. The support material may form a chair back and/or a seat for the chair to provide support to the chair occupant. The support material may be made from a textile of interwoven strands wherein some of the interwoven strands include copper containing particles such as copper iodide or copper oxide within the textile fibers.

A conductor joint (1) is provided for connecting two conductors along a longitudinal direction. The conductor joint comprises a first segment having a first segment end (202) adapted connecting to an end portion of a first conductor and a second segment (300) comprising a second segment end (302) relative to the longitudinal direction adapted for receiving a second conductor end of a second conductor. The second segment further has an opposite second segment end (304) fixed, or forming an integral part with, an opposite first segment end (204) of the first segment (200), a tubular sleeve (310) and a core rod (320) wherein ends (310a, 320a) of the tubular sleeve (310) and the core rod (320) are arranged with a radial offset forming a sleeve opening for receiving at the end portion of the second conductor end of the second conductor.

An electromagnetic shielding material includes multiple strands of an electrically conductive yarn that are arranged as a braided, knitted, or woven mesh. Each strand of the electrically conductive yarn comprises one or more electrically conductive filaments; each electrically conductive filament comprises a core of a first electrically conductive material surrounded by a sheath of a second electrically conductive material different from the first electrically conductive material. The first electrically conductive material exceeds the second electrically conductive material with respect to electrical conductivity, while the second electrically conductive material exceeds the first electrically conductive material with respect to one or more of tensile strength, corrosion resistance, or one or more other mechanical or chemical properties or characteristics. In many examples, the first electrically conductive material includes copper and the second electrically conductive material includes stainless steel.
