Abstract: A sensor system configured to detect oxygen in an exhaust stream of an industrial process is provided. In one embodiment, the sensor system comprises a probe with an oxygen-detecting sensor, wherein the oxygen-detecting sensor detects a concentration of oxygen in the exhaust stream. The system may also comprise a catalytic converter located on the probe near the sensor, wherein the catalytic converter is configured to convert carbon monoxide to carbon dioxide. The system may also comprise a signal detector configured to detect a change in oxygen concentration indicative of a carbon monoxide breakthrough.

Abstract: A process analytic instrument includes a measurement cell and an analyzer circuit. The measurement cell includes a solid state electrochemical oxygen sensor configured for exposure to a process gas. The analyzer circuit is coupled to the solid state electrochemical sensor to measure an electrical parameter of the solid state electrochemical sensor and provide an output indicative of oxygen in the process gas. A DC bias circuit is configured to selectably bias the solid state electrochemical oxygen sensor with a direct current when the solid state electrochemical sensor is in a reducing environment.

Abstract: An improved infant carrier seat rocker is provided for a typical molded plastic type infant carrier seat embodying a rounded bottom to facilitate a fore and aft rocking motion. This type of seat is currently in production. The rocker is comprised of a housing from which a lifting member protrudes. A power unit is mounted within the housing. This power unit provides rotational energy. A drive means consisting of an eccentric mounted to the output of the drive unit and slidably connected to the lifting member to convert rotational energy to vertically reciprocating motion is employed to impart the vertical motion to the lifting member. The lifting member in turn imparts this motion to a suitable feature of the carrier seat, typically the lower edge of the seat, and the seat then rocks as the lifting member oscillates vertically.
