  • Publication number: 20100219305
    Abstract: A bracket for coupling a component to a vehicle including a mounting structure defining an aperture is disclosed. The bracket has a first portion including at least one mounting structure clip configured to engage the mounting structure about a periphery of the aperture. The bracket also has a second portion including a component clip configured to engage the component.

  • Patent number: 7635402
    Abstract: An air filter system for an internal combustion engine of a vehicle can have an indicator for signaling restricted flow of air through a replaceable air filter member mounted to a filter assembly. At least one sidewall can be associated with the replaceable air filter member to be positioned with an air stream passing through the air filter member. A resettable air filter status indicator can provide a visually perceivable signal external of the filter assembly. The resettable air filter status indicator can be integrally formed in the sidewall for indicating if a mounted air filter member requires replacement in response to air intake differential pressure with respect to atmospheric pressure on a downstream side of air flow through the replaceable filter member being above a predetermined threshold value.

  • Publication number: 20020097395
    Abstract: A LCD test system is provided for use in a high volume production environment. An automated test is performed that tests each LCD and provides a pass/fail indication. The automated test includes an image-sticking test that drives the test image based on a control voltage that corresponds to a maximum rate of change of brightness. The control voltage is determined by differentiating an electro-optic curve. The brightness difference between the test image and another test image is compared to predetermined threshold. The other test image may be a gray scale test. Alternatively, the image-sticking test may integrate brightness levels of odd and even frames, compare these results to predetermined thresholds. The test includes a color uniformity test in which average differences in peak reflectance and peak frequency within sections of the LCD are compared to predetermined thresholds for the pass/fall indication. The test includes a spatial distribution of defects test.
