Abstract: Methods and apparatuses for testing image sensors are disclosed. Desirable apparatuses of the present invention include image sensor testing devices comprising a digital light projection system capable of projecting static or dynamic images onto an image sensing device under test and an image sensor signal detection means for analyzing the output of said image sensing device under test. The digital light projection system comprises a light source, collimating optics, a digital micromirror device, and focusing optics. Other desirable methods and apparatuses of the present invention include image sensor testing devices employing a digital light projection system capable of simultaneously testing a plurality of image sensors. According to the present invention, the light source is calibrated and converted to a desired test image by the digital micromirror device. The test image is then focused onto an image sensor, the output of which is read by a detector and correlated with the input digital test image.

Abstract: A snap on wheel cover that includes a plurality of finger elements that cooperate with a locking ridge on lug nuts that are used to secure a wheel onto a vehicle hub. The plurality of finger elements include first finger elements that engage a first surface of the locking ridges of the lug nuts when the wheel cover attached to the wheel and second finger elements that engage and apply a biasing force to a second opposite surface of the lug nuts when the wheel cover attached to the wheel. Third finger elements can also be provided which are configured to be deflected inward when contacted by either the first or second side of the locking ridges of the lug nuts.

Abstract: Inserts that are configured to be placed in gaps provide between wheel covers and underlying wheel of wheel assemblies. The inserts are made from materials that are suitable rigid and strong so as to reinforce and protect the overlying portions of the wheel cover from impact damage such as denting in the case of metal wheel covers and cracking or breaking in the case of plastic wheel covers. The inserts further prevent otherwise hollow portions of the wheel assembly from sounding, feeling or seeming hollow.

Abstract: A wheel cover snap fastens to stylized lug nuts of a wheel using resilient retainers that are integrally fastened to the wheel cover. The stylized lug nuts correspond and axially extend through apertures in the wheel cover when the wheel cover is assembled to the wheel. The retainers are secured to an inboard face of the wheel cover and correspondingly engage the stylized lug nuts to retain the wheel trim assembly to the wheel such that retainers are not visible when the wheel trim assembly is viewed from a direction normal to the outboard face of the wheel cover. The apertures are sized in relation to annular flanges on the lug nuts and to the resilient tabs of the retainers such that the wheel cover and/or annular flanges of the lug nuts conceal the retainers from view, and thereby provide an uninterrupted chrome appearance.

Abstract: An ornamental wheel cover integrally retained on the lug nuts of a vehicle wheel that provides positive positioning of the cover to the lug nuts. The lug nuts preferably have a flange that defines an upper shoulder. The cover is provided with a number of elongated tubular extensions axially projecting from the cover that are each partially slotted to provide a plurality of cantilevered fingers. Each finger has an undercut groove that has a shoulder which positively positions the cover to the upper shoulder of the lug nuts of the wheel. Below the undercut groove is a bulbous portion that contacts the lug nut below the flange. When the cover is attached to the wheel, the elongated tubular extensions are aligned with the lug nuts and the cover is moved axially inwardly of the wheel so that the cantilevered fingers separate slightly as the bulbous portions pass over the flange of the lug nut.
