  • Patent number: 9183746
    Abstract: When performing video-based speed enforcement a main camera and a secondary RGB traffic camera are employed to provide improved accuracy of speed measurement and improved evidentiary photo quality compared to single camera approaches. The RGB traffic camera provides sparse secondary video data at a lower cost than a conventional stereo camera. The sparse stereo processing is performed using the main camera data and the sparse RGB camera data to estimate a height of one or more tracked vehicle features, which in turn is used to improve speed estimate accuracy. By using secondary video, spatio-temporally sparse stereo processing is enabled specifically for estimating the height of a vehicle feature above the road surface.

  • Patent number: 9111136
    Abstract: A multi-view imaging system for Vehicle Occupancy Detection (VOD) including a gantry mounted camera and illuminator to view the front seat of vehicles, and a roadside mounted camera and illuminator to view the rear seat of vehicles. The system controls the illuminator units to preserve/maximize bulb life, thus reducing the service cost of the system. In one embodiment, a target vehicle's license plate is read. If the vehicle is on a pre-approved list to use the HOV lane, then no further interrogation of the vehicle is performed. If the vehicle is not on the pre-approved list, then the front seats are interrogated by a camera and illuminator located on an overhead gantry as the vehicle continues down the highway. If the front seat analysis indicates that the passenger seat is not occupied, then the system interrogates the rear seats using a separate camera and illuminator located on the roadside.

  • Patent number: 8760317
    Abstract: An upstream vehicle detection system captures images of a vehicle as it travels through a high occupancy vehicle (HOV) lane or high occupancy vehicle tolling (HOT) station and generates an hypothesis as to whether the vehicle is complying with HOV or HOT rules based on image analysis. A database of historical information about various vehicles' compliance with HOV or HOT rules is consulted to determine whether the vehicle has previously been identified as a potential violator and pulled over by law enforcement as a result. If the vehicle was previously pulled over by law enforcement and determined to be complying with HOV or HOT rules (a false positive), then the violation hypothesis may be weighted in favor of not pulling the vehicle over.

  • Patent number: 8582819
    Abstract: In response to determining that a target vehicle is at large, identification information associated with the target vehicle's license plate may be retrieved and used to generate one or more synthetic license plate images. The synthetic license plate images may be subjected to one or more transformation to cause them to resemble authentic license plate image captures and/or to mimic authentic license plate image captures from existing and operational ALPR system cameras. Target signatures may then be calculated from the synthetic license plate images. Upon capturing an authentic license plate image using an ALPR system camera, a signature of the authentic license plate image may be calculated. If a match is found between the signature of the authentic license plate image and a target signature, law enforcement may be alerted that the target vehicle was detected at the location of the ALPR system camera.

  • Patent number: 7686298
    Abstract: A method of removing media lateral DC position errors in a long paper path using closed loop correction is disclosed. The amount of lateral DC media shift error generated (or the lateral DC correction required) in the paper path is sensed by a CCD or full width array sensor located in the downstream paper path. In the closed loop, this information is used to energize a motorized actuator in the upstream paper path to correct for lateral DC errors in the media path. Thus, the paper is delivered to the downstream media path within specifications.

  • Publication number: 20070146459
    Abstract: A maintenance system and method for maintaining an imaging member of an imagining device includes a pre-cleaning device to clean the imaging member; an applicator to apply release agent to the imaging member; a metering device to meter release agent on the imaging member; a reservoir to remotely store release agent; and a pump to supply the applicator with release agent from the reservoir. The saturation level of the applicator is monitored and maintained within a predetermined range. The applicator, pre-cleaning device and metering device may be independently actuated to engage the imaging member. Release agent collected by the pre-cleaning device and/or metering device may be recycled. Debris collected by the pre-cleaning device and/or metering device may be stored and/or removed.

  • Publication number: 20060279620
    Abstract: A system for applying a liquid to a support surface in an imaging apparatus comprises an application surface that applies liquid to the support surface; and a filter positioned in relation to the application surface such that liquid removed from the support surface passes through the filter to the application surface. The filter includes a low-friction, low-fiber shed permeable layer in contact with the application surface.

  • Publication number: 20060221124
    Abstract: A reflex printing device having multiple print heads mounted at different locations around the circumference of the drum at different “angles” and an encoder disk mounted on the drum to allow for detection of the drum position as a function of time. An image defect due to a misalignment in the print process direction of the output from the multiple print heads is corrected by detection of an encoder position error function subtracted from itself shifted by the angle between the print heads.
