Abstract: A seal assembly includes an outer member and an annular seal. The outer member includes an outer wall and a landing. The outer wall has a cylindrically shaped inner surface disposed about an axis and configured to oppose an outer cylindrical surface of a port. The landing extends radially inward from the inner surface of the outer wall. The annular seal member is disposed about the axis and has an inner cylindrical surface, a bottom axial surface, an outer cylindrical surface, and a circumferential groove. The inner cylindrical surface of the seal member is configured seal with the outer cylindrical surface of the port. The circumferential groove is open at the outer cylindrical surface of the seal member and extends radially inward. The landing extends into the circumferential groove and is in sealing contact with the circumferential groove.

Abstract: A computer-implemented apparatus and method for operating vibrational testing equipment which conducts vibrational testing upon automobile components. Raw engine acceleration data is gathered from a running car so that a sine on random calculation may be performed upon that data. The sine on random calculation uses peak hold envelope data and sin tone data as determined from the acceleration data. Thereupon, an iterative equalization technique operates upon the peak hold envelope data and sine tone data to generate a vibrational testing specification. The vibrational testing specification defines how the vibrational testing equipment should operate by specifying such parameters as the gain, the sweep duration, and the time to run the vibrational test in order to achieve a particular reliability and confidence level.
