摘要:
A detection system (12) for a vehicle (10) to detect the presence of one or more object (88) relative to the vehicle (10) comprises a module housing (24), a radar sensor component (96) located within the module housing (24) for emitting a radar beam (42) and receiving reflected signals (94) in a detection mode. The radar sensor component (96) comprises means (128) for emitting a defrost beam (68) in a defrost mode; the defrost beam (68) overlapping the radar beam (42). The detection system (12) further comprises an absorber material (64) located in the field of view (70) of the defrost beam (68) to absorb the energy of the defrost beam (68) and to warm up in view to provide a defrosting effect.
摘要:
A level measurement device for measuring a level (L) of a product (1), in particular a product contained in a container (5), comprising: mounting means (3) for mounting said measurement device at a measurement site, an antenna (9) comprising a dielectric antenna element (11) for transmitting microwave signals (S) towards the product (1) and/or for receiving echo signals (R) resulting from reflections of the transmitted microwave signals, and measurement electronics (15) for determining the level (L) of the product (1) based on a transit time needed for the microwave signals to travel to a surface of the product (1) and of their echo signals to return to the device, is described allowing to prevent deposits to build up, which may eventually impair transmission and/or reception of the signals. To this extent, the measurement device according to the invention comprises a cap (25) covering said dielectric antenna element (11) and cleaning means (27) for cleaning said cap (25) are foreseen, which cause said cap (23) to vibrate when they are activated.
摘要:
Die Erfindung betrifft eine Anordnung zum Enttauen und/oder Enteisen eines Radarsensors (10) in einem Kraftfahrzeug (100), wobei der Radarsensor (10) ein Gehäuse (11) mit einem Strahlungsfenster (12) zum Abstrahlen und/oder Empfangen von Radarwellen aufweist, wobei der Radarsensor (10) dazu ausgebildet ist, hinter einem Stoßfänger (102) des Kraftfahrzeugs (100) angeordnet zu sein, und mit einer einen Auslassbereich (14) für Luft aufweisenden, schlauchförmigen Einrichtung, wobei der Auslassbereich (14) derart angeordnet ist, dass die Luft zumindest mittelbar auf die Außenseite des Gehäuses (11) und/oder des Strahlungsfensters (12) einwirkt. Erfindungsgemäß ist es vorgesehen, dass die schlauchförmige Einrichtung ein Entlüftungsschlauch (15) ist, der dazu ausgebildet ist, den Innenraum des Kraftfahrzeugs (100) zu entlüften.
