A monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated, line by line, from a linear image source (36) and projected, as a real intermediate image, near the focal surface (22) of a curved mirror (24) by means of a scanning ball lens

A monocentric arrangement of optical components providing stereoscopic display of a virtual image, electronically generated, line by line, from a linear image source (36) and projected, as a real intermediate image, near the focal surface (22) of a curved mirror (24) by means of a scanning ball lens assembly (100). To form each left and right intermediate image component, a separate image generation system (70) comprises a scanning ball lens assembly (100) comprising a spherical lens (46) for wide field of view and a reflective surface (102). A monocentric arrangement of optical components images the left and right scanning ball lens pupil at the corresponding left and right viewing pupil (14) of the observer (12) and essentially provides a single center of curvature for projection components. Use of such a monocentric arrangement with linear image source (36) and scanning ball lens assemblies (100) provides an exceptionally wide field of view with large viewing pupil (14).

A method of attaching a plurality of types of wheel liners to a plurality of types of vehicle wheels mounted by a lug bolt extending through and beyond a lug nut using a jam nut having a first straight cylindrical extension member, comprising the steps of: (a) providing the wheel liner defining a hole sufficient in size to pass therethrough the first straight cylindrical extension member of the jam nut; (b) placing the wheel liner adjacent to the vehicle wheel so that the hole of the wheel liner aligns with the lug bolt of the vehicle wheel; and (c) holding the wheel liner against the vehicle wheel by frictionally engaging the jam nut to the lug bolt through the hole so that the first straight cylindrical extension member contacts the lug nut and the wheel liner is spaced from the lug nut without distorting the wheel liner. 5. A method of attaching a plurality of types of wheel liners to a plurality of types of vehicle wheels mounted by a lug bolt extending through and beyond a lug nut using a jam nut having a first straight cylindrical extension member and a second straight cylindrical extension member, comprising the steps of: (a) providing the wheel liner defining a hole sufficient in size to pass therethrough either the first straight cylindrical extension member or the second straight cylindrical extension member of the jam nut; (b) placing the wheel liner adjacent to the vehicle wheel so that the hole of the wheel liner aligns with the lug bolt of the vehicle wheel; and (c) holding the wheel liner against the vehicle wheel by frictionally engaging the jam nut to the lug bolt through the hole so that either the first straight cylindrical extension member or the second straight cylindrical extension member contacts the lug nut and the wheel liner is spaced from the lug nut without distorting the wheel liner. 6. A kit for attaching a wheel liner to a vehicle wheel mounted by a plurality of lug bolts extending through and beyond a plurality of lug nuts, comprising: the wheel liner defining a plurality of holes; a plurality of jam nuts having a jam nut body, a first axial extension extending from the jam nut body, and a second axial extension extending from the jam nut body, wherein the jam nut body, the first axial extension, and the second axial extension define a threaded bore therethrough; and a package containing the wheel liner and the plurality of jam nuts, wherein each hole defined by the wheel liner is sufficient in size to pass therethrough the second axial extension of the jam nut. 7. A kit for attaching a wheel liner to a vehicle wheel mounted by a plurality of lug bolts extending through and beyond a plurality of lug nuts, comprising: the wheel liner defining a plurality of holes; a plurality of jam nuts having a jam nut body, a first axial extension extending from the jam nut body, and a second axial extension extending from the jam nut body, wherein the jam nut body, the first axial extension, and the second axial extension define a threaded bore therethrough; and a package containing the wheel liner and the plurality of jam nuts, wherein the first and second axial extensions are of different lengths so that the jam nut can be reversed for either the first axial extension or the second axial extension to fill a different amount of space located between the wheel liner and the vehicle wheel. 8. A wheel liner assembly, comprising: a vehicle wheel having a plurality of openings; a plurality of lug bolts, each lug bolt received by a corresponding one of the plurality of openings of the vehicle wheel and having an end portion; a plurality of lug nuts, each lug nut engaging a corresponding one of the plurality of lug bolts so that the vehicle wheel attaches to a vehicle and the end portion of the plurality of lug bolts extends through and beyond the plurality of lug nuts; a wheel liner having a plurality of holes, each hole receiving a corresponding one of the end portions of the plurality of lug bolts; a plurality of jam nuts, each jam nut engaging a corresponding one of the end portions of the plurality of lug bolts, each jam nut having a jam nut body, a first axial extension extending from the jam nut body, and a second axial extension extending from the jam nut body, wherein the jam nut body, the first axial extension, and the second axial extension define a threaded bore therethrough; and a plurality of jam nut covers, each cover removeably attached to a corresponding one of the plurality of jam nuts so that each jam nut cover conceals each jam nut regardless of the orientation of the jam nut. 9.
