    • The present invention is for a system and method for determining the proximity of a mobile device to a location without the use of a satellite based or other location awareness system, nor a stationary beacon of any kind. Instead, the mobile device monitors radio frequency broadcast identification codes from nearby mobile devices, and determines if the set of detected identification codes is sufficiently similar to a weighted set of identification codes attributed to specified location. If the calculation of similarity meets the confidence conditions of the system, notification is made that the customer or visitor has arrived. The invention utilizes a combination of confidence interval computation, machine learning, and fault tolerance mechanisms to optimize the success of correctly detecting that the device is near the relevant location.
    • 本发明涉及一种用于在不使用基于卫星或其他位置感知系统以及任何类型的固定信标的情况下确定移动设备与位置的接近度的系统和方法。 相反,移动设备监视来自附近移动设备的射频广播识别码,并且确定检测到的识别码集合是否与归因于指定位置的加密的识别码组相当。 如果相似度的计算符合系统的置信条件,则通知客户或访问者已到达。 本发明利用置信区间计算,机器学习和容错机制的组合来优化正确检测设备在相关位置附近的成功。

    • 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.
    • 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恢复。 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。

    • 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.
    • 一种用于识别使用对象级散列表重复先前完成的作业的打印作业的方法和系统。 接收的打印作业可以被解析为有意义的对象类,并且可以为每个类中的对象和每个打印作业计算哈希值表。 包括散列值表的概要可以与作业特定设置一起保留在数据库中。 然后,可以将新遇到的作业声明为基于与作业存储数据库中的先前作业的哈希值相匹配的新作业的哈希值的先前作业的重复。 在用于打印作业提交的通用文档格式(例如PDF)中,对象类可以很容易地确定。

    • An energy-absorbing system for vehicle door assemblies is provided, including first and second brackets and a reaction plate. Each bracket attaches to an inner support panel of the door assembly via a mounting portion having leg members extending inward from opposing ends thereof. The reaction plate includes a generally planar portion with a flange portion extending from an upper edge thereof. One side of the reaction plate is attached to an inner surface of a trim panel, whereas the other side is attached to the leg members of the first and second brackets. One section of the flange portion abuts against an underside surface of an armrest assembly, and another section abuts against a b-side surface of a pull-handle. Both brackets are configured to sustain a minimum vertical loading condition (limit vertical deflection), and controllably deform under a threshold lateral loading condition to absorb and attenuate kinetic energy resulting therefrom.
