Abstract: The present invention provides an optical fire sensor device and a corresponding fire detection method. The optical fire sensor device is equipped with an optical particle detection unit (10), which is configured to ascertain measured values of a particle number in a measurement volume range (FA) as a function of a particle size in a predetermined particle size range and/or as a function of a particle speed in a predetermined particle speed range, a fire detection unit (20), which is configured to ascertain respective distributions of the measured values and to compare at least one parameter of the ascertained distributions to at least one predetermined criterion. The fire detection unit (20) is configured to detect a fire (B) in consideration of the comparison. An alarm unit (30, 40) is used to output an alarm signal in response to the detection of the fire (B) by the fire detection unit (20).

Abstract: Methods, systems, and computer program products for generating a setting recommendation to configure a revenue management system of a travel provider. The setting recommendation may be generated by collecting data from a articles provided by data sources associated with a given market. Each article may be compared to a filter in a set of filters to determine whether the article meets a criterion of the filter. If an article meets the criterion of a filter, the article may be parsed and data may be selectively collected for use in forecasting a future event regarding the given market. A recommended action may be generated based on the future event. Information regarding the recommended action, the filter, the article, and the future event may be provided in a setting recommendation for use in updating a system setting in an effort to address the effect of the future event.

Abstract: Fire detector installations comprise fire detectors as sensor devices for detecting fires, smoke, flames or other signs of fire, and are used in both public buildings, such as schools or museums, and in private buildings. The invention relates to a fire detector device (1) for detecting fires and or signs of fire in an area to be monitored, said fire detector device comprising a camera element (2) for recording image data in the area to be monitored, and an evaluation element (7) designed to detect a fire or signs of fire by evaluating the image data. The fire detector device (1) is designed as a multi-criteria detector and comprises at least one other sensor element (3, 12, 13, 14) for fire detection.
