Vorrichtung und Verfahren zum Klimatisieren von Fahrzeugen unter Vermeidung eines innenseitigen Beschlagens von Fenstern

Abstract: Klimaanlage fur ein Fahrzeug mit einem Raum (33), der zumindest ein Fenster (32) aufweist, das mittels einer Luftstromung einstellbarer Temperatur heizbar ist, wobei die Klimaanlage umfasst: ein Verteilersystem (11, 34, 35), das Luftstromung zu dem Fenster lenkt, einen Kompressor (2), und ein mit dem Kompressor in Verbindung stehendes Warmetauschersystem (7, 8), das einen Verdampfer (7) und ein Geblase (36) zum Fuhren von Luft uber den Verdampfer (7) aufweist, und eine Steuereinrichtung (40), die mit dem Kompressor (2) und dem Geblase (36) verbunden ist, wobei die Klimaanlage weiter einen mit der Steuereinrichtung (40) verbundenen Umgebungsluft-Temperatur-Sensor (15) zum Ermitteln der Umgebungstemperatur auserhalb des Fahrzeugs und einen mit der Steuereinrichtung (40) verbundenen Solar-Sensor (18) zum Ermitteln der Intensitat der Sonneneinstrahlung aufweist, wobei die Steuereinrichtung (40) zum Aktivieren des Kompressors (2) ausgebildet ist, einen Zeitgeber zum Ermitteln einer ersten Zeitspanne, in der das Fahrzeug auser Betrieb gewesen ist, und...

BLACK-CACTUS: embedded training using a battle management language in a swedish command and control system

Abstract: The Net Centric and Global Information Grid (GIG) visions envision systems that will be interconnected to support multi-lateral, civilian and military missions. The constantly changing environment requires commanders and leaders to plan for missions that allow for units from various nations, agencies, etc. to join or separate from the team, depending on the situation, as the mission unfolds. Training performed at home stations and in mission training/mission rehearsal may occur just days, hours or even minutes before the actual missions. This need for rapid mission-specific rehearsal capabilities and multilateral environment drives requirements to 1) develop a simulation infrastructures that enable embedded simulation capability in the operational systems and 2) develop interoperability mechanisms that enable a more agile, dynamic and adaptive interconnection of heterogeneous simulations.In this paper the lessons learned from the novel BLACK-CACTUS project (Bi-LAteral Collaboration and Knowledge exchange -- Command And Control To US and Sweden) is presented. The project shows an agile method of integrating Command and Control Systems and Computer Generated Force engines using the Command and Control Lexical Grammar (C2LG) together with the Widely Integrated Systems Environment (WISE) integration platform. The C2LG is the semantic glue that ties the information parts together and WISE is the framework for disseminating information through several of protocols and information models. The BLACK-CACTUS Proof of Principle consisted of the C2LG GUI, the TVT Vehicle Battle Management System (VBMS), the Joint Semi Automated Forces (JSAF) Simulation, the WISE platform, and the Joint Battle Management Language (JBML) web server and services.This paper presents the architecture, the implementation and the rational why a C2LG together with integration methods provides agile Joint/Coalition Embedded C2 Training Environments.

Comparison of measured and predicted scattering coefficients at 94 GHz

Abstract: In the summer of 1991, the backscattering from various background surfaces were measured at 94 GHz. A frequency modulated radar was mounted in a skylift and the backscattering coefficients at HH and VV were estimated at different angles of incidence. The test surfaces included bare sand and soil surfaces, an asphalt road and lawn. Soil-moisture was sampled and surface roughness profiles were recorded using a laser profiler. In the analysis of the data, the measured backscattering coefficients were compared with predictions from different kinds of scattering models, such as the geometric optics and physical optics approximations, the field perturbation approximation and the integral equation model (IEM). Comparisons were also made with Lambert scattering and approximative solutions for fractal surfaces. The vegetation measurements were compared with predictions using a cloud model of dielectric discs. The results of the radar measurements showed that all the tested soil and sand surfaces generated incoherent scattering at 94 GHz with a weak dependence on the angle of incidence. An exception was the asphalt surface, however, and detailed comparisons with different scattering models were carried out using the autocorrelation function of the measured surface profile as input. The best agreement between measured and predicted scattering coefficients was obtained using the IEM-model. >
