摘要： 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.

摘要： What is disclosed is a novel system and method to reduce noise induced by color mixing in a color management system. At least one device color recipe is obtained for a target spot color. The recipe is defined for a color marking device and defines a range of marking device color values for a target L*a*b color value. Next, a minimal value and a maximum value of each color value in the range of color values for said target L*a*b color value are identified. An iterative process of searching is performed until the printed color test patch produces a visually acceptable smoothness while matching color accuracy. This iterative process includes generating at least one additional new device color recipe from color values within the range of color values. At least one of the new device color recipes is selected and provided to the color marking device for rendering.

摘要： A method and system of color management for an image marking device. A sensor measures printed hardcopy colors. A first gain, computed by a linear controller based on a linear model, is scheduled for each color node of a sampled color space. For each node where a convergence error exceeds a threshold, a second gain is scheduled by a nonlinear controller. The second gain scheduling includes initializing operational parameters, and performing an iterative procedure. The iterative procedure includes computing gain matrices over a defined projection horizon, evaluating a cost function for each gain matrix, determining the cost function, scheduling a new gain based on selecting a gain matrix having the minimum value of the cost function, and computing new CMYK values based on the new gain. A multidimensional LUT based on the scheduled gain matrices is generated and stored in memory, and a hardcopy output image is generated based on the stored multidimensional LUT.

摘要： What is disclosed is a novel system and method for characterizing a model-based spectral reflectance sensing device. In accordance with the teachings hereof, measurements of training samples taken with a previously manufactured ‘fleet master’ sensing device are adapted, in a manner more fully disclosed herein, based upon knowledge of the wavelengths of the illuminators used for both the subject and fleet master sensors, as well as spectral reflectance response of the training samples as measured by a reference spectrophotometer device. Utilizing the adapted measurements of the fleet master device, a reconstruction matrix can be quickly constructed for the subject sensor. The present system and method provides reasonably good accuracy using pre-existing measurement data. This results in manufacturing cost savings on a per-sensor basis.

摘要： A computerized system, method, and software apparatus is presented which reduces the black level of the printing process in order to substantially remove stray black dots from the finished product of a printing output. Black levels are reduced by updating the print engine regions for the colors W, C, M, Y, MY, CM, CY, and neutral and by assigning a weights each color. The values are used to compute CMKY values. These values are then placed in a gain matrix and stored in a computer memory.

摘要： What is disclosed is a novel system and method for quickly and accurately determining whether a color is inside or outside the boundary of a surface of a color gamut. The present method enables a gamut mapping algorithm to quickly identify points which require further processing and those which are already inside the gamut and thus do not need to be processed by the gamut mapping function. The present method can be performed directly on the printing device to determine whether the colors are in/out of the actual gamut surface of the target marking device. Other embodiments have also been disclosed.

摘要： Methods and planning systems used to schedule gain matrices for process control loops and determine optimal values for manipulated variables according to a minimum cost function. A cost function is calculated for each of a predetermined number of plans as a sum of partial cost functions calculated over a predetermined number of projections in a horizon. Each partial cost function after the initial projection of a plan is calculated using a scheduled gain matrix. The gain matrix can be scheduled for each projection by selection from a predetermined set of gain matrices or can be calculated in real time during the calculation for each projection.
