A reaction carrier (14) has a flow channel (42) defining a reaction chamber (46) having a optically detectable reaction material (48), that reacts with a gas mixture component or with a reaction product. The measuring device (12) includes a gas-conveying assembly (2) with a gas-conveying apparatus (28) conveying the gas mixture and a detection assembly (3), which has a lighting apparatus (37) for lighting the reaction chamber (46), an optical sensor (38) for sensing the optically detectable reaction, and an evaluating unit (4) evaluating sensor data and determining a concentration of the component of the gas mixture. The detection assembly (3) senses a speed of a reaction front (6) propagating in the flow direction in the reaction chamber (46) and determines a preliminary concentration from the speed of the reaction front (6).

  • Patent number: 9678467
    Abstract: A developer detector includes a sensor housing portion, an optical sensor, and a cleaning portion. The sensor housing portion can be installed on a wall surface of a hopper storing a developer. The sensor housing portion includes a detection surface, and a step surface protruding a smaller amount from the wall surface than the detection surface to form a step height from the detection surface. The optical sensor is housed in the sensor housing portion and detects the developer through the detection surface. The cleaning portion moves in a moving region including a first region facing the detection surface and a second region facing the step surface and cleans the detection surface on the way of moving. The cleaning portion includes a flexible member and makes the flexible member slide on the detection surface while making the flexible member contact the detection surface under pressure in the first region.

  • Patent number: 9606311
    Abstract: A method includes obtaining a substrate having at least one exposed metal surface. The method also includes electro-depositing metal onto the at least one exposed metal surface of the substrate and around at least a portion of an optical fiber to secure the optical fiber to the substrate. The substrate and the electro-deposited metal are configured to remove heat from the optical fiber. The method could further include electro-depositing metal around a sacrificial material and removing the sacrificial material to form at least one cooling channel through the electro-deposited metal. The optical fiber could include a polymer coating, where a portion of the polymer coating is removed at an end of the optical fiber. The substrate and the electro-deposited metal could be faceted at an input of the optical fiber and at an output of the optical fiber. The optical fiber could have a coiled arrangement on the substrate.
