An approximately "V"-shaped feature is disposed below the combination feature. The V-shaped feature is oriented at an oblique angle from vertical with the closed end of the V disposed upper right. The legs of the V are slightly curved, with the concave sides oriented upwardly. The legs have variable thickness and terminate on the lower left in points. The foregoing vertically stacked devices are followed by capital letters SES in sans serif font. The height of the capital letters SES is smaller than the height of the stacked devices. The capital letters SES are followed on the right by the words Seismic Equipment Solutions in sans serif font. The words Seismic Equipment Solutions are stacked vertically. The character size of the stacked words is such that the height of the stacked words is approximately the same as the height of the letters SES..
