Abstract: An optical fiber connector assembly includes a body (22) with passages (26) that hold optical fibers and a backshell (24) that can be removed and slid along the optical fiber cable to provide access to the fibers so a selected fiber can be removed while the rest of the fibers continue to carry signals. The removable backshell carries a mechanism (150) that can be manually operated to unlatch the connector from a housing (12), despite removeability of the backshell. The mechanism includes a cam (152) rotatable about the cable-receiving aperture (32) in the backshell and a cam follower (142) that is pushed forwardly by rotation of the cam. The cam follower presses forwardly against a pair of release elements (130) in the body to cause them to deflect a pair of latch arms (120) out of engagement with shoulders (124) of the body so the body can be pulled rearwardly out of the housing.

Abstract: An optical fiber connector system includes first and second mateable connectors (12, 14) with fiber blocks (32,72) that hold optical fiber termini (50), wherein forward (F) movement of the second connector housing (70) toward the first housing (30) results in automatic latching together of the fiber blocks with the latches taking the forces of termini springs that have been partially compressed. The second fiber block (72) can slide within the second housing (70) between front and rear positions, and is held in the front position by a cam (90) that engages a free end (104) of a cam follower arm (103) of the second housing. As the connectors mate, a rigid second fiber block latch (100) deflects a resilient first housing latch end (62) and rides forward of it until faces of the blocks are close together.

Abstract: A method of fault identification in a plasma process powered by an RF source comprises initially determining, in respect of a given baseline plasma process, the changes in magnitude of a plurality of Fourier components of the RF source resulting from changes in a plurality of the process input parameters from their baseline values. These magnitude changes are stored as reference data. During a subsequent production run, the plasma process is monitored for faults and if one is found the baseline process is repeated with input parameter values nominally the same as the original baseline values. The changes in the Fourier components from the original baseline values are determined and compared with the reference data to determine which input parameter(s) have changed.

Abstract: A diagnostic imaging simulator is disclosed that includes a three-beam emitting mobile hand piece. The-mobile hand piece is moved around a reference surface that mimics an anatomical region of a patient. A detector identifies the position of the three beams on the surface and a location determining device determines the location of the mobile hand piece from those positions. A display then displays an image associated with the location of the mobile hand piece, which is preferably an image corresponding to that provided by a real imaging machine in a similar position.

Abstract: The gas sample identification apparatus transmits at least one beam of light of predefined frequency band through a gas sample present in a gas sampling chamber. The presence and concentration of various agents in the gas sample are determined by a linear variable filter that selectively passes the light beam transmitted through the gas sample chamber to an array of detectors. The detectors are positioned to receive only a narrow passband component of the light beam. The output signals from the array of detectors is processed by a multivariate statistical processor to accurately identify both the presence and concentration of one or more agents contained in the gas sample.
