Abstract: A method for detecting and monitoring the fill level of a fluid in a storage tank, the method comprising: detecting an initial fluid level within the tank using a sensing circuit; periodically sampling the fluid level at a first sampling rate; detecting a change in fluid level indicative of a fill process; increasing the sampling rate to a second, higher rate in response to the detected change; displaying the updated fluid level to an operator in real-time or near real-time; determining that the fill process has ceased based on fluid level stability; and reverting the sampling rate to the first sampling rate upon cessation of the fill process.

Abstract: A head-up display assembly includes a liquid crystal display element, a first backlight light source, and a remote backlight light source. The first light source is physically mounted in proximity to the liquid crystal display element, and is operable to directly backlight illuminate the liquid crystal display element. The remote light source mounted physically remote from the liquid crystal display element, and is operable to backlight illuminate the liquid crystal display element via a light guide.

Abstract: A LCD display comprises a backlight assembly that includes a backlight substrate, one or more first white LEDs coupled to the backlight substrate and configured to produce a first light output, and one or more second white LEDs coupled to the backlight substrate and configured to produce a second light output. A light integration unit is coupled to the backlight assembly and configured to produce a combined output from the first light output and the second light output, the combined output having a desired luminance and chrominance. A LCD assembly is coupled to the light integration unit.

Abstract: A projection system includes a vibration controlling structure. The projection system includes an imaging unit mounted to a movable platform via a partially compliant mount structure, such that the imaging unit is partially isolated from the platform while projecting an image which is stable with respect to the platform. The imaging unit and partially compliant mounting structures are constructed and arranged to damp vibrational forces on the imaging unit.

The exit pupil of the image source is configured such that the exit pupil of the image source underfills the entrance pupil of the lens for portions of the image source that are not in the center portion of the image field.

Abstract: Methods and apparatus are provided for reducing the visual artifacts exhibited by a display employing individually addressable pixels. The apparatus comprises an array of pixels, each pixel having a switchable region of alterable transparency or luminance and a non-switchable region. The switchable region of each pixel is distributed, that is, divided into at least two simultaneously switched portions at least partly separated by a significant portion of the non-switchable region. The first order spatial harmonics and visual artifacts are significantly reduced. For a color display, each color pixel is similarly subdivided.

Abstract: Method and apparatus are provided for displaying an image to a viewer with reduced visual artifacts. The apparatus comprises a display panel for forming the image using an array of pixels with distributed active regions, and a viewing arrangement optically situated between the display panel and the viewer for transferring the image formed on the display panel to the viewer with limited angular pixel subtense. The distributed active regions of the pixels are desirably divided into at least two simultaneously switched portions at least partly separated by or surrounding a significant portion of the non-switchable region. First order spatial harmonics and associated artifacts are reduced by the distributed apertures and second order and higher harmonics are reduced by limiting the pixel subtense angle seen by the viewer. A significant reduction in visual artifacts arising from the periodic structure of the display panel is obtained.

Abstract: Methods and apparatus are provided for a combined image on a head-up display. A data image display provides a first part of a combined image. An optical input provides a second part of the combined image, e.g., the background scene. A combiner superimposes the first and second parts to provide the combined image to the viewer. The data image display preferentially delivers s-polarized light to the combiner, which has a selective reflectance region for preferentially reflecting s-polarized light in a wavelength region of interest. In a preferred embodiment, the data image display comprises a backlight, a liquid crystal layer and two polarizers oriented so that the data images directed toward the combiner are s-polarized with respect to the selective reflectance region. A polarization rotation element may also be used in the data image display to facilitate s-polarization orientation.

The projection lens unit may be used with an illumination unit having a light source and optics conditioning the light from the light source prior to illumination of a light valve. The selective filter may optionally be positioned at a conjugate plane to the aperture stop in the illumination unit.
