The mark consists of the wording "MRO PLUS" and design elements. The tail of the letter "R" consists of an arrow design that extends down partially beneath the letter "O". The inside of the letter "O" forms a hexagon. The word "PLUS" appears smaller than "MRO" and inside a polygon to the right of "MRO".

EXTREME-GUARD

Thermistors; negative temperature coefficient (NTC) thermistors; electric resistances; temperature sensors; resistance temperature detectors (RTDs) in the nature of resistance thermometers; resistive temperature devices in the nature of temperature sensors

The mark consists of the wording "U.S. SENSOR CORP." with design elements. The first design element is that the letters "U.S." appear outlined with empty space within the letters. The second design element is that the word "SENSOR" appears solid except that there are four horizontal lines running through it, which lines are formed by negative space such that the letters appear broken up by the horizontal lines.
