  • Patent number: 9129159
    Abstract: A video-based vehicle headlight state monitoring method and system. A vehicle image can be captured by an image-capturing unit and converted to a grayscale image. The grayscale image can be processed to locate a front license plate and identify a position of a headlight region in front of the vehicle utilizing an algorithm. An average digital count with respect to brightness of the headlight region can be compared with average digital count with respect to brightness of several parts of the vehicle and a background region to determine the vehicle headlights ON/OFF status. The headlights can be considered ON if the digital count level of the headlight region is higher than the digital count of the several parts of the vehicle and the background region. A warning signal can be initiated to turn the headlights on during a special situation utilizing a signal generator.

  • Patent number: 9097614
    Abstract: What is disclosed is a system and method for testing a motorized vehicle's exhaust emissions in a non-controlled emissions testing environment. In one embodiment, the present system comprises a toll collection structure having a sensor for obtaining information about a registered owner of a motor vehicle and about the motor vehicle itself, as the vehicle travels on a lane which passes through the structure. At least one emissions detector, which is fixed to the toll collection structure, performs an emissions test on the vehicle by analyzing an exhaust plume emitted by the vehicle. Speed/acceleration of the vehicle is also measured. In various embodiments hereof, the emissions detector comprises a combination of dispersive or non-dispersive infrared detector and a dispersive or non-dispersive ultraviolet detector. Emissions data collected is automatically compared to emissions standards and an authority is notified if that the vehicle does not meet those standards. Various embodiments are disclosed.

  • Patent number: 8955434
    Abstract: A digital flexography system includes an imaging member with a charge generating layer formed from an array of addressable pixels and a charge transport layer thereon. Ink is delivered to the imaging member using a simple rough donor roll, rather than an anilox roll. Instead of controlling the amount of ink delivered using the anilox roll, the amount of ink is controlled by the pixels on the imaging member.

  • Patent number: 8854223
    Abstract: What is disclosed is a system and method for image-based determination of concentration of CO and CO2 in a vehicle's exhaust gas in an emissions testing environment. In one embodiment, the present method involves receiving an IR image of the exhaust plume of a motor vehicle intended to be tested for CO and CO2 concentrations. The IR image has been captured using a mid-wave infrared camera with at least one optical filter tuned to the infrared absorption band of CO and CO2. The images are pre-processed to isolate pixels which contain the exhaust plume. The intensity values of pixels in those isolated regions are normalized and concentrations of CO and CO2 are determined via a calibration curve which relates pixel intensities to concentrations. The concentrations are compared to an emissions standard set for the vehicle to determine whether the vehicle is a gross polluter.

  • Patent number: 8715202
    Abstract: What is disclosed is a system and method for image-based determination of carbon dioxide (CO2) concentration in exhaled breath. In one embodiment, an image of the exhaled airstream of a subject of interest is received. The image is captured using a mid-wave infrared camera system having an optical filter tuned to the infrared absorption band of CO2. The image is preprocessed to isolate a region of pixels containing the exhaled airstream and intensity values of pixels in the identified region are normalized by a value of a known radiance such as that of the subject's nose or face. The image is analyzed to determine CO2 concentration levels of the exhaled airstream using a calibration curve which relates pixel intensity to CO2 concentrations. The calibration curve is derived using a physics-based parameterized model. The CO2 concentration levels are determined and communicated to a computer workstation. Various embodiments are disclosed.

  • Publication number: 20130242097
    Abstract: What is disclosed is a system for non-contact, video-based determination of vehicle component failure due to overheating. In a manner more fully disclosed herein, at least one infrared camera is used to capture an infrared image of a component of a vehicle to be inspected for overheating. The images are processed to isolate that component. A temperature is estimated for the isolated component in the image using a camera calibration curve which relates pixel intensities to temperature. A temperature threshold for the isolated component is retrieved from a database based upon a classification of the vehicle. The estimated temperature is then compared to that component's temperature threshold. If the estimated temperature is above the retrieved threshold, a signal is initiated. The teachings hereof find their uses in a variety of remote and non-cooperative vehicle inspection modes in the field of transportation safety. Various embodiments are disclosed.
