Patent number: 9533772Abstract: A visual search assistance system and related operating method are disclosed. An exemplary embodiment of the method dynamically determines a desired line-of-sight vector from an occupant of a vehicle to a visual target, and dynamically determines, with an onboard tracking system of the vehicle, an actual line-of-sight vector for the occupant of the vehicle. The actual line-of-sight vector is temporally associated with the desired line-of-sight vector. The method compares the actual line-of-sight vector against the desired line-of-sight vector to obtain a difference measurement, and generates a notification when the obtained difference measurement exceeds a threshold value. The notification provides guidance to redirect a gaze direction of the occupant toward the visual target.Type: GrantFiled: July 9, 2014Date of Patent: January 3, 2017Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Pedro Davalos, Robert E. De Mers, John F. L. Schmidt, Mohammed Ibrahim Mohideen

Patent number: 9395539Abstract: 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.Type: GrantFiled: February 28, 2007Date of Patent: July 19, 2016Assignee: HONEYWELL INTERNATIONAL INC.Inventors: John F.

Patent number: 9093041Abstract: Methods and apparatus are provided for compensating a liquid crystal display for changes in brightness level. The apparatus comprises a variable brightness back-light optically coupled to a display panel whose properties depend upon back-light brightness. An electrical circuit measures back-light brightness and/or display flicker and sends this information to a controller. The controller automatically determines a display panel compensation signal based on back-light brightness and/or display flicker, and sends this compensation signal to the display panel to optimize the display panel properties for the commanded or observed back-light brightness level or flicker level so as to, for example, minimize display panel flicker and/or ghost image retention. Such automatic compensation is especially useful for head-up displays that must accommodate large variations in display brightness, e.g.Type: GrantFiled: November 28, 2005Date of Patent: July 28, 2015Assignee: HONEYWELL INTERNATIONAL INC.Inventors: John F.
