The techniques of this disclosure relate to determining an optical characteristic of a camera. The device includes a housing that receives a test fixture retaining a camera. The housing includes a first segment and a second segment creating a chamber surrounding the camera. The first segment is attached to the test fixture and defines a first orifice located in a side of the first segment. The first orifice directs a flow of a gas out of the chamber. The second segment defines a second orifice located in a first side of the second segment to direct the flow of the gas into the chamber. An aperture is located in a second side of the second segment and positioned opposite the test fixture to define a field of view that includes a camera target. The aperture receives a lens barrel of the camera and enables the determination of the optical characteristic.

Device for determining an optical characteristic of a camera

A vehicle windshield display system for detecting obstruction of a vehicle operator's field of view by a windshield display. The system provides closed-loop feedback to perform a visual check of what is actually being displayed on a windshield display in order to avoid obstructing an operator's field of view. The system includes a windshield display configured to be installed into a vehicle and configured to display a graphic in a field of view of an operator of the vehicle, a camera configured to determine an image of the graphic displayed by the windshield display, and a controller configured to determine if the image indicates that field of view is obstructed. The camera is used to monitor the windshield display and provide feedback to the controller so that appropriate adjustments to the graphic being displayed can be made.

A head up display system having a diffusing image plane or diffuser. The light output of a relatively small image source is imaged on the diffuser by way of imaging optics. A mirror is used to image light from the diffuser onto a windshield and correct for distortion caused by the windshield. The diffuser is advantageously used when a large field-of-view is desired, or sun load characteristics need to be addressed. The diffuser may be flat or curved in order to optimize the system for different applications. The magnification of the mirror may be made relatively low, and the solar energy density that is made incident on the image source is reduced, providing for a low cost, high performance, color head up display system.

An improved weight estimation apparatus includes a closed elastomeric bladder filled with fluid and installed in the foam cushion of a vehicle seat bottom, with at least one pressure sensor installed in a closed exit port of the bladder. A temperature sensor disposed in proximity to the bladder provides a temperature signal, and a controller estimates the weight of the occupant based on the temperature and pressure signals. The pressure sensor is preferably configured to sense the gage pressure--that is, the differential pressure between the fluid and atmospheric pressure--at the center of gravity of the fluid in order to provide a stable output independent of changing atmospheric pressure and changing orientation of the bladder due to vehicle pitch and roll.
