Abstract: A radiometer is provided. The radiometer includes a sensor and a radiation transparent dome. The radiation transparent dome surrounds the sensor. The radiometer also includes one or more fluid nozzles. The one or more fluid nozzles are adapted to apply a fluid on the radiation transparent dome in order to clean the surface of the radiation transparent dome.

Abstract: A value data system, including a database component, including: initiative data representing at least one initiative, said at least one initiative being adapted to deliver value to a customer of an organisation; risk data associated with said initiative data, said risk data representing risks corresponding to said at least one initiative; task data associated with said initiative data, said task data representing tasks to be performed to perform said at least one initiative, said tasks including risk mitigation tasks for mitigating said risks; and value data associated with said initiative data, said value data representing values delivered to said customer as a result of performing said at least one initiative; and a user interface component for defining said initiative data, said risk data, said task data, said value data and the associations between said initiative data, said risk data, said task data, and said value component data; and for defining value data representing values delivered to said customer

Abstract: In a device for determining the ozone concentration by utilizing the surface chemiluminescence effect having a fan (13), a chemiluminescence element (8), a photomultiplier (6), a temperature sensor (16), and control electronics (12), an airflow generated by a fan (13) passes via a suction pipe (7) and an adjoining light trap system (17) through a venturi-shaped channel structure (2) along a metal block (9) in which a temperature sensor (16) is housed. The device is calibrated with respect to the temperature dependence of the reaction of a chemiluminescence disc (8) attached to the bottom of the metal block by determining the output voltage of a photomultiplier (6) in dependence on the temperature at a predetermined ozone concentration in the measured air.
