摘要： What is disclosed is a system and method for encoding and decoding data in a color barcode pattern using dot orientation and color separability. The spectral (wavelength) characteristics of the CMY colorants, commonly used in digital printing, and those of RGB sensors are exploited to achieve high capacity data embedding rates in color barcodes. The present method embeds independent data in two different printer colorant channels using dot orientation modulation. In the print end, dots of two colorants occupy the same spatial region. At the detector end, by using the complementary sensor channels to estimate the colorant channels, data is recovered in each colorant channel. The method approximately doubles the capacity of encoding methods based upon a single colorant channel and enables embedding rates which match or exceed that of other hardcopy barcodes known in the arts. The method is robust against inter-separation misregistration with a small symbol error rate.
摘要翻译：公开的是使用点取向和颜色分离来对彩色条形码图案中的数据进行编码和解码的系统和方法。通常用于数字印刷的CMY着色剂和RGB传感器的光谱（波长）特性被利用来实现彩色条形码中的高容量数据嵌入率。本方法使用点取向调制将独立数据嵌入两种不同的打印机着色剂通道。在打印端，两个着色剂的点占据相同的空间区域。在检测器端，通过使用互补传感器通道来估计着色剂通道，数据在每个着色剂通道中被回收。该方法基于单个着色剂通道使编码方法的容量大大增加一倍，并且使嵌入速率匹配或超过本领域已知的其它硬拷贝条形码的嵌入速率。该方法对于具有小的符号错误率的分离间对位失调是鲁棒的。

摘要： A support bracket for an armrest assembly having a pull-handle or pull-cup is provided for use in a motorized vehicle. The support bracket includes a generally horizontal support member configured to extend, at least in part, adjacent to or through an internal cavity of the pull-handle/pull-cup. The support bracket also includes at least two, but preferably three leg members spaced apart from one another and operatively attached at respective first ends to the support member. Each leg member extends downward from the support member in an oblique manner to attach at a respective second end to an inner support panel. The leg members are configured to sustain a predetermined minimum vertical loading condition, and controllably deform under a predetermined threshold lateral loading condition. The leg members create a load path for transferring vertical loads imparted to the armrest assembly to the vehicle interior surface as a substantially vertical force.

摘要： A color look-up table (CLUT) is compressed in a lossless manner. The CLUT includes nodes that convert values of a first color space to corresponding values of a second color space. The CLUT is received in a serialized node-by-node manner. For each of some of the nodes the following is performed in the order in which the nodes are received in the serialized node-by-node manner. First, a difference value is determined that represents compression of a value of the node, in accordance with a hierarchical differential encoding approach or in accordance with a cellular interpolative prediction approach. Second, the difference value is stored in lieu of the value of the node being stored, to compress the value of the node in the lossless manner.

摘要： A method and system for identifying print jobs that are repeats of a previously completed job utilizing an object level hash table. Received print jobs can be parsed into meaningful classes of objects and a table of hash values can be computed for objects in each class and for each print job. A synopsis comprising the table of hash values can be retained in a database along with the job specific settings. A newly encountered job can be then declared as a repeat of a previous job based on the hashes for the new job that match the hash values for the previous job stored in the database. The classes of objects are readily determinable in common document formats used for print job submission, such as PDF.

摘要： Methods and systems used to associate color calibration profiles with scanned images based on identifying the marking process used for an image on a substrate using spatial characteristics and/or color of the image. Image types which are classified and identified include continuous tone images and halftone images. Among halftone images separately identified are inkjet images, xerographic images and lithographic images. Locally adaptive image threshold techniques may be used to determine the spatial characteristics of the image.

摘要： Methods and apparatus for spectrally-encoding plural source images and for providing the spectrally-encoded plural source images in a composite image, for rendering the composite image in a physical form, or for recovering at least one of the encoded source images from the rendered composite image such that the recovered source image is made distinguishable. The rendered composite image may be subjected to a varying field of illumination, generated, for example, by a switched sequence of individually activated, differing illuminants. This sequenced array of illuminants causes a corresponding sequence of source images to be recovered in rapid succession, thus imparting a sense of change, such as motion, between or within the recovered source images.
