Debunking the patent 7493601
Abstract
Patent 7493601 believes that the three systems, Electrical System, Fluid System and Thermal
System are equivalent systems. The laboratory experiments were designed and being carried out
to test out whether the claims made were valid. Using the result collected from the experiments,
the data were analyzed and the claims would then be determined whether they can be made.
The transfer function was derived, and the corresponding time constant was determined for each
system so that the claims can be determined whether it is true. The 63.2% method was used to
identify the parameters of the system and identify the experimental time constant. The actual
time constant was also concluded from the experiment and will be compared to the experimental
time constant to make a conclusion. From the experiment, we found that the electrical system has
a theoretical time constant of 0.22s, and the time constant found through the 63.2% method was
0.34s which led to an error of 54.55%. On the other hand, the fluid system has a theoretical time
constant of 239.86s and the time constant found through the 63.2% method was 185s which led
to an error of 22.87%. As for the thermal system, it has a theoretical time constant of 260.64s and
the time constant found the 63.2% method was 312s which led to an error of 19.71%. Therefore,
the conclusion made from this experiment was that the thermal system and fluid system were
equivalent but the electrical system was not equivalent to the thermal and fluid system.
Introduction
A ME421 student has been awarded the contract to work together with Grunch and Tromby,
Attorneys at Law to do a few experiments to test out the claim in Patent 7493601. The Patent
7493601 contains an Electrical System, a Fluid System and a Thermal System, and the Patent
claims that all these three systems are equivalent. The Electrical System experiment consists of a
series circuit of a 2200 Ω resistor and a 100 μF capacitor and the output voltage is measured
across the capacitor. On the other hand, the Fluid System consists of a cylindrical tank with
2.5-inch diameter and 9 inch height and an output valve with the resistance of 43,000 m-1s-1.
Furthermore, the Thermal System consists of a 25ml conical flask with 15 grams of water on a
