Three-dimensional scene reconstruction from set of two dimensional images for consumption in virtual reality
To enable better sharing and preservation of immersive experiences, a graphics system reconstructs a three-dimensional scene from a set of images of the scene taken from different vantage points. The system processes each image to extract depth information therefrom and then stitches the images (both color and depth information) into a multi-layered panorama that includes at least front and back surface layers. The front and back surface layers are then merged to remove redundancies and create connections between neighboring pixels that are likely to represent the same object, while removing connections between neighboring pixels that are not. The resulting layered panorama with depth information can be rendered using a virtual reality (VR) system, a mobile device, or other computing and display platforms using standard rendering techniques, to enable three-dimensional viewing of the scene. |

Quantum cascade laser optimized for epitaxial side-down mounting
For epitaxial-side-down bonding of quantum cascade lasers (QCLs), it is important to optimize the heat transfer between the QCL chip and the heat sink to which the chip is mounted. This is achieved by using a heatsink with high thermal conductivity and by minimizing the thermal resistance between the laser active region and said heatsink. In the epi-down configuration concerned, the active region of the QCL is located only a few micrometers away from the heatsink, which is preferable from a thermal standpoint. However, this design is challenging to implement and often results in a low fabrication yield if no special precautions are taken. Since the active region is very close to the heatsink, solder material may ooze out on the sides of the chip during the bonding process and may short-circuits the device, rendering it unusable. To avoid this happening, the invention proposes to provide a trench all around the chip with the exception of the two waveguide facets, i.e. the ends of the active region. This trench may be etched into the otherwise standard QCL chip or otherwise machined into the chip, providing an initially empty space for the volume of solder displaced by the chip during the epi-down bonding process, which empty space is occupied by the surplus solder without contacting the side of the chip and thus short-circuiting the device. |

An image adjuster alters the pixel values for pixels located outside the field of view of an end user so that degradation of OLED material occurs in a balanced manner, such as by reducing illumination of blue OLED material, which tends to degrade at a more rapid rate than red and green OLED material. |

Fault-tolerant LCD display
A fault-tolerant LCD display system comprises an LCD panel and a first driver coupled to the LCD panel and including a first gate driver and a first source driver, the first driver including a first transient voltage suppressor. A second driver is also coupled to the LCD panel and includes a second gate driver and a second source driver, the second driver including a second transient voltage suppressor. One of the first and second drivers is operable to be active while the other is inactive, and vice versa, and the first and second drivers are isolated from one another. The first and second transient voltage suppressors are operable to prevent a back biasing voltage from leaking back through the inactive driver and thus the transient voltage suppressors are operative to prevent a back biasing voltage from shunting through the non-active driver. |

Vision-assist devices and methods of detecting a classification of an object
Vision-assist devices and methods are disclosed. In one embodiment, a vision-assist device includes an image sensor for generating image data corresponding to a scene, a processor, and an auditory device. The processor is programmed to receive the image data from the image sensor, perform object recognition on the image data to determine a classification of a detected object that is present within the scene, and determine a confidence value with respect to the classification of the detected object. The confidence value is based on a confidence that the classification of the detected object matches an actual classification of the detected object. The processor further generates an auditory signal based on the confidence value. The audio device receives the auditory signal from the processor and produces an auditory message from the auditory signal. The auditory message is indicative of the classification of the detected object and the confidence value. |

Cooperative automated vehicle system
A cooperative-vehicle system suitable to operate an automated vehicle in a courteous or cooperative manner includes an object-detector and a controller. The object-detector is used by the host-vehicle to detect an other-vehicle attempting to enter a travel-lane traveled by the host-vehicle. The controller is in communication with the object-detector. The controller is configured to control motion of the host-vehicle. The controller is also configured to adjust a present-vector of the host-vehicle to allow the other-vehicle to enter the travel-lane. The decision to take some action to allow the other vehicle to enter the travel-lane may be further based on secondary considerations such as how long the other-vehicle has waited, a classification of the other-vehicle (e.g. an ambulance), an assessment of how any action by the host-vehicle would affect nearby vehicles, the intent of the other-vehicle, and/or a measure traffic-density proximate to the host-vehicle. |
