A directional coupler having (a) a first coupled microstrip section having a first terminus (T1) and a second terminus (T2), (b) a second coupled microstrip section having a first terminus at T2 and a second terminus (T3), and (c) a first phase-velocity-compensating capacitor connected across the conductors of the microstrip sections at T2 is disclosed. The coupler also may include a second phase-velocity-compensating capacitor connected at T1, and a third phase-velocity compensating capacitor connected across the conductors at T3.

Railcars for personal vehicles provides train passengers with a method for bringing their automobile with them as they travel. This system utilizes pallets and fork-lifts specially designed to hold automobiles. Vehicles can be loaded and unloaded from both sides of a railcar making for fast and easy loading. This system allows travelers and commuters to ride on public transportation with the convenience of having their own vehicle for transportation one they have reached their destination.

An audio fidelity meter includes a scale which uses colors to visually represent the fidelity of an encoded digital audio file based at least on its extracted bit rate. The bit rate is one of several digital audio quality descriptors. Other descriptors include format, source, bit width, and sample rate. The extracted bit rate is fed into a lookup table for processing. One or more of the other descriptors can also be extracted and fed in combination with the extracted bit rate into the lookup table for processing. The lookup table stores information on various digital audio formats, sources and associated bit rates, bit widths and sample rates in the form of a database. The input bit width, sample rate, format, originating source and/or bit rate is/are compared against the database to generate a digital audio quality output. The output may be visually displayed via the scale, a fidelity meter needle and an associated numerical bit rate display.

Therapeutic applications, such as prevention, treatment and supplementation, for the use of novel and other thiolatocobalamins to protect human cells against the effects of oxidative stress. In particular, this invention relates to the use of a novel synthetic thiolatocobalamin, glutathionylcobalamin to protect animal cells against oxidative stress damage. This invention also relates to the use of thiolatocobalamins, such as glutathionylcobalamin, in lieu of current, commercially available forms of vitamin B12 for the treatment and prevention of conditions associated with oxidative stress damage and for dietary supplementation.
