Abstract: In the known injection of an auxiliary signal during the re-coding of the binary user data signal into a path code, the control voltage of a clock phase-locked loop is also amplitude-modulated in the transmission-end code converter, so that the clock signal generated and the user data signals sent onto the transmission path are phase-modulated. The limited phase shift restricts transmission capacity for the auxiliary signal, and furthermore interference of the user data signal may occur due to the generated phase jitter. According to the invention, the user data signal is therefore transmitted in CMI code and, when the latter is generated, a binary signal content is assigned to at least one of the element combinations excluded by the CMI code rule, and only the start of a one bit or a zero bit of the auxiliary signal is marked. <IMAGE>

Abstract: An air flow and filtration control system in the form of a headgear which is worn by a physician during a surgical procedure, a technician during an assembly process, or any other user wherein a controlled air flow and air filtration is required or desired. The flow through system includes a relatively rigid, open frame, skeleton headgear structure which substantially surrounds the head of the wearer. The structure includes ductwork and is adjustably attached to a headband formed of straps which are adapted to snugly engage the head of the wearer. A plurality of fans or other air moving devices are mounted in the structure. The fans are positioned to move air through the integral ducts in the structure. A shroud (or hood) is draped over and attached to the structure in such a fashion as to completely cover the structure and to cover at least a portion of the wearer in order to maintain sterile or controlled conditions. A relatively planar transparent screen or "window" is provided at the front of the apparatus for substantially undistorted viewing. Typically, the trasnsparent screen is mounted in the shroud and is removable therewith. Filtration devices are formed or mounted in the shroud so as to be disposed adjacent to the fans when the shroud is placed over the structure. A suitable power supply, such as a battery pack or the like, is used to selectively power the fans. It is anticipated that at least the shroud (and the components mounted thereto) will be disposable. <IMAGE>
