Abstract
An engine-oil dipstick having a magnet having a cap assembly that is configured to removably attach to a dipstick entry orifice of a combustion-engine sump; a dipstick element having a first end and a second end; the first end of the dipstick element attached to the cap assembly; a magnet that generates a magnetic field, the magnet having a first half and a second half; the second half of the magnet being closer to the second end of the dipstick than the first half of the magnet; the second half of the magnet being substantially encapsulated within the dipstick element.
Claims2
An engine-oil dipstick having a magnet comprising:
- a cap assembly that is configured to removably attach to a dipstick entry orifice of a combustion-engine sump;
- a dipstick element having a first end and a second end;
- the first end of the dipstick element attached to the cap assembly;
- a magnet that generates a magnetic field,
- the magnet having a first half and a second half;
- the second half of the magnet being closer to the second end of the dipstick than the first half of the magnet;
- the second half of the magnet being substantially encapsulated within the dipstick element;
- the dipstick element having a dipstick-element first half that includes the first end and a dipstick-element second half that includes the second end;
- and
- an orifice in the dipstick-element second half configured to allow visibility of the magnet.
An engine-oil dipstick having a magnet comprising:
- a cap assembly that is configured to removably attach to a dipstick entry orifice of a combustion-engine sump;
- a dipstick element having a first end and a second end;
- the first end of the dipstick element attached to the cap assembly;
- a magnet that generates a magnetic field,
- the magnet having a first half and a second half;
- the second half of the magnet being closer to the second end of the dipstick than the first half of the magnet;
- the second half of the magnet being substantially encapsulated within the dipstick element;
- the second half of the magnet having a second-half-of-the-magnet surface area;
- the portion of the second end of the dipstick that substantially encapsulates the second half of the magnet having an exterior surface;
- the exterior surface having an exterior-surface surface area;
- and
- the exterior-surface surface area being greater than the second-half-of-the-magnet surface area.
