  • Patent number: 10473506
    Abstract: The present invention relates to oil level visualization system that is used in place of a conventional dipstick to measure oil level. The system may include a strip that has a tube attached thereto comprising an oil absorbent material. Oil from the oil reservoir is configured to absorb to the oil absorbent material and absorbing of the oil to the oil absorbent material is configured to provide a stain on the oil absorbent material visible to the naked eye. The present invention also relates to methods of using the same.

  • Patent number: 10066978
    Abstract: The present invention relates to oil level visualization systems. In some embodiments, the system includes an engine comprising an oil reservoir configured to hold oil; a dipstick configured to be disposed in the oil reservoir and measure oil level in the oil reservoir; a strip comprising a front surface comprising an oil absorbent material and a rear surface configured to confront the dipstick; and a fastener configured to removably attach the strip to the dipstick. In other embodiments, a strip comprising an oil absorbent material is provided in place of a conventional dipstick. In both embodiments, oil from the oil reservoir is configured to absorb to the oil absorbent material and absorbing of the oil to the oil absorbent material is configured to provide a stain on the oil absorbent material visible to the naked eye. The present invention also relates to methods of using the same.

  • Patent number: 8132647
    Abstract: A tree step system 100 having a tubing 110; and a step lag screw 130, whereby the tubing 110 may be used as a hammer to drive the step lag screw 130 into a tree 20 and the tubing 110 may further be used for leverage to turn the step lag screw 130 into the tree. The tree step system 100 may include a rod step 150, and an adjustable fastener 170 for adjusting the depth of the adjustable fastener 170 and preventing the tree step system 100 from rotating. The rod step centerline may be offset ninety degrees from the centerline of the step lag screw 130, whereby the offset provides for ease of climbing and entering a tree stand with the proper foot. The tubing 110 may comprise an upper tubing 114 and a lower tubing 124 for ease of installation.
