Abstract
An improved fluid level verification apparatus with an integral, internal source of illumination that is powered by an integral, internal energy source and is activated by a motion sensor or any other sensor commonly known in the art to detect the presence of a person in dark or dimly lit environments. The preferred light source is a light emitting diode (LED). A second embodiment of the integral, internal source of illumination that is powered by an integral, internal energy source and is activated by a motion sensor or any other sensor commonly known in the art to detect the presence of a person in dark or dimly lit environments is applied to a fluid reservoir tank.
Claims14
In a fluid level verification apparatus for a fluid container comprising:
- at least one end member;
- said end member in communication with said container;
- a light source disposed within said end member that illuminates said container;
- a sensor, integrated with said end member, to detect a presence of a foreign body;
- said sensor coupled with said light source in order to activate said light source upon detection of a foreign body;
- the improvement comprising:
- said light source comprising an incoherent light emission device.
A fluid level verification apparatus for a fluid container, the apparatus comprising:
- a transparent tube defining a chamber and having oppositely disposed ends;
- a pair of longitudinally spaced apart end members, said respective end members each having a cylindrical projection extending therefrom and in axially aligned relationship with said transparent tube;
- and each being in fluid communication with said transparent tube and said container;
- an incoherent light emission device disposed within one of said end members that illuminates said transparent tube;
- a sensor, integrated with one of said end members, to detect a presence of a foreign body;
- and
- said sensor coupled with said incoherent light emission device in order to activate said incoherent light emission device upon detection of said foreign body.
