Abstract: A fuel level indicator system that utilizes a resistor card having an arc-shaped resistive path with a first set of spaced apart conductor lines and an arc-shaped resistive ink material overlying the first set of conductor lines. The first conductor lines are formed at an angle with respect to a radial line drawn from the center of the resistive path arc. The resistor card also has an arc-shaped continuously solid conductor base and a second set of spaced apart conductor lines extending from the base at an angle with respect to a radial line drawn from the center of the arc-shaped conductor base. The system includes a wiper assembly having a pair of spaced apart arms. Each arm has a plurality of parallel fingers extending from one end. One of the fingers on a first arm engages a conductor line on the resistive path and a second finger on the first arm engages an adjacent conductor line along the resistive path.

Abstract: A golfing stroke trainer mat is provided with both back stroke and follow-through markings. Specifically, there are perpendicular and longitudinal lines running the length of the mat that aid in club head alignment and path. Measurement numbers to provide feedback on the length of both the back and follow through strokes. Uniquely, the invention can have colored matching sections to aid in the matching of the length of the strokes with or with out the numbering. The mat can be designed with colored lines, and/or lines having varying widths. Both of these schemes are designed to aid the golfer in controlling a pendulum stroke with equal back and follow through strokes. Another feature of the invention is that the golf clubs are marked with both a longitudinal and lateral line to match the lines on the golf mat. The mat is designed with a V shaped notch beginning at the center of the rectangular mat and extending to one of the longer ends.
