Abstract: An active window display (AWD) system having a first surface that provides a wide field of view image for cross-cockpit viewing that is readable against sunlight illumination is provided. The displayed image in the AWD is not visible from a backside (or second surface) of the AWD. The AWD system further capably switches from transmitting wavelengths to being opaque, to block the optical emissions associated with a displayed image from escaping the backside or second surface.

Abstract: A method for detecting and correcting drift associated with operation of a hybrid tracking system is provided. The method obtains a data signal from a first tracker subsystem having a first tracker latency time; for a defined window of time, the method captures snapshot input data for a second tracker subsystem having a second tracker latency time which is longer than the first tracker latency time; and captures synchronized data from the data signal which corresponds to the defined window of time; wherein the defined window of time comprises a time duration shorter than the second tracker latency time, to capture the snapshot input data. The method further determines a level of drift associated with operation of the first tracker subsystem; and adjusts operation of the first tracker subsystem according to the determined level of drift.

Abstract: A system and method for optimizing image uniformity in a head-up display (HUD) are provided. An imaging subsystem is characterized in that if light of a first uniformity is propagated therethrough, an uncompensated image would be displayed to a user via uncompensated image light. The uncompensated image light has first and second portions with respective first and second values of a radiant property. A difference between the first and second values is a first amount. The light source is configured to emit source light of a second, predetermined uniformity through the imaging system such that a compensated image is displayed to the user via compensated image light. The first portion of the compensated image light has a third value of the radiant property, and the second portion of the compensated image light has a fourth value of the radiant property. A difference between the third and fourth values is less than the first amount.

Abstract: A system and method are provided for leveraging emitted polarized electromagnetic radiation as a means to track relative orientation and position of an object with regard to another object. Six basic degrees of freedom including three angular and three translational are determined based on making multiple polarization-based measurements and then determining the corresponding geometry that would yield those measurements.

Abstract: A system and method for controlling a proximity display system by providing the ability to rapidly blank and un-blank the display is provided. The system and method enable modifying, blanking and un-blanking in response to the detected location of the viewer's eye. The system and method optionally provide the viewer with cueing information that directs the viewer's eye toward the eyebox in response to detecting that the viewer's eye is out of the eyebox.

Abstract: A system and method of displaying a conformal-capable head-up display image is provided. Distortions caused by combiner curvature, for example, are removed by pre-distorting and projecting separate images for each eye. Shutter-based eyewear controls the visibility as the imagery is cycled, e.g., shuttered, between left and right eyes. The combined image generator, projector and eyewear system maintains minimal vergence errors, minimal dipvergence errors, acceptable average transmittance, and optionally, high conformality.

Abstract: A head-up display system and method are provided that suppress double images from a combiner by eliminating or reducing a reflection of a refracted image from the back surface of the combiner. The combiner contains a tilted axis polarizing structure that attenuates transmittance and subsequent reflection of a refracted polarized projector image but maintains high transmittance for the forward external scene imagery.

Abstract: A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.

Abstract: A system and method of displaying a conformal-capable head-up display image is provided. A pre-distorted right-eye image and a pre-distorted left-eye image are separately generated and projected toward a windscreen. The pre-distorted right-eye image is reflected off of the windscreen to supply a reflected right eye image to a right eyebox, and the pre-distorted left-eye image is reflected off of the windscreen to supply a reflected left eye image to a left eyebox. The reflected right-eye image and the reflected left-eye image are each non-distorted images.

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: Systems and methods of controlling the touch sensitivity of a projected capacitive touch detection system are provided. The temperature that is at least representative of the touch sensitive region temperature is sensed. Based on the sensed temperature, the numbers of the capacitive touch sensors that have different strength electric fields applied thereto are varied and/or the relative magnitudes of the different electric fields are varied. When installed in a vehicle, the operational state of the vehicle may also impact this operation.
