Abstract: Methods and sensors for the detection, identification, and quantification of one or more gas species, including volatile organic compounds, in a test sample are described. Methods employ gas sensors comprising a diffusion matrix present on the sensor surface. A gas analyte in a test sample diffuses through the matrix and is detected upon interaction of the analyte with the sensor. A response profile of a gas sensor to a gas analyte in the test sample is compared to a control gas sensor response profile determined in a similar manner for a known gas species. Comparisons of test sample and control sample sensor response profiles enable detection, identification, and quantification of a gas species analyte in a test sample.

Abstract: A sliding door system employs an electric power link. The electric link includes a ribbon conductor which is enclosed in a protective chain-like guard to provide electrical communication between the sliding door and the door header. Electrical modules such as electromagnetic locks, switches and sensors are mounted directly on the sliding door. Safety sensors are mounted at the leading and trailing edges of the sliding door panels to sense whether an obstacle or traffic has cleared.

Abstract: A connecting rod has a rod member formed from fiber reinforced plastic material secured to a cap member to define the big end of the connecting rod. Securement is by a metal member rigidly attached to the rod member, to which the cap member is secured. Attachment of the rod member and the metal member is via a locally transversely expanded end portion of the rod member enclosed within a similarly shaped (e.g. wedge shaped) cavity in the metal member such that the expanded end portion cannot be withdrawn axially of the rod member from the cavity.

Abstract: The integrity and connection of cable wires (10-13) extending between two banks of terminals (20-1 to 20-4 and 16-19) are checked for shorts of the wires to ground, to battery wiring between each other and for opens and misconnections or cross-connections of the wires. Unique recognition circuits are provided for controlling, analyzing (circuits 43, 53, 68, 92, 112, 181) and displaying (displays 23, 24, 31 and 32) the test results to accordingly apprise an operator(s) stationed at either or both ends of the cable.
