Abstract: A hospital bed has wireless communication circuitry operable to transmit wirelessly bed status data. A surface supported by the bed has wireless communication circuitry operable to transmit wirelessly surface status data. The wireless communication circuitry of the hospital bed and the wireless communication circuitry of the surface communicate with a network independently. A hospital bed with an integrated surface has wireless communication circuitry operable to transmit wirelessly bed status data and surface status data. The wireless bed status data and the wireless surface status data are received by wireless access points of a network of a healthcare facility.

Abstract: A device for use in joining wires such as electrical conductors is disclosed. The device comprises a ferrule, the exterior surface of which is covered with a coat or layer comprising an explosive composition. The method of joining includes coaxially aligning the end portions of two wires within the ferrule and then detonating the explosive composition to produce a metallurgical bond between the ferrule and each wire end. Apparatus for forming the novel splice is also disclosed.

Abstract: A method of forming a laminate is disclosed. The method comprises placing a metal film in juxtaposition to a surface to be joined thereto. A buffer medium having an explosive charge on at least one surface thereof is positioned proximate the film. The explosive charge is detonated to propel the film against the surface to shear a portion of the film, corresponding in shape to the surface, away from the buffer medium to bond the sheared portion to the surface.
