Abstract: A latch includes a cup, a latch assembly mounted in the cup and having a pivotal handle and a lock having a lock pawl selectively rotatable to a locked position to prevent operation of the latch assembly.

Abstract: An ellipsoidal infinite element is used for the modeling of electromagnetic fields in exterior domains surrounding a structure. This infinite element is based on a multipole expansion that describes scattered and/or radiated fields exterior to the structure. The electromagnetic field is represented in the exterior domain by a pair of scalar potentials, referred to as the Debye potentials.

Abstract: In an improvement over conventional finite element techniques, an ellipsoidal infinite element is used for the modeling of acoustic fields in exterior, fluid-filled domains surrounding a structure. This ellipsoidal infinite element is based on a multipole expansion that describes, to arbitrary accuracy, any scattered and/or radiated field exterior to an ellipsoid. Significantly, the respective eccentricities of the three elliptical cross sections of the ellipsoid can take values that are arbitrary and mutually independent. The ellipsoidal infinite element is readily incorporated in any structural or acoustic finite element code.
