    • A method and apparatus are provided for classifying range profiles, generated for example by a radar, lidar or sonar. In the method, each in a set of objects of interest is modeled with a probabilistic model. The probabilistic model represents the probabilities of occurrence of different possible sequences of distances between selected features of the object, in different orientations, that are likely to result in peaks of backscatter in a range profile of the object. The probabilistic model is derived from a first probabilistic representation of each selected feature, generated to represent the uncertainty in locating the feature and the uncertainty in observing the feature in a range profile. Classification is achieved by calculating, for each probabilistic model, the probability that the model would generate a given sequence of distances between observed backscatter events in a given range profile. The model generating the given sequence with the greatest probability identifies the object likely to have produced the given range profile. Preferably, the probabilistic models comprise Hidden Markov Models (HMMs).
    • 提供了一种用于对由雷达,激光雷达或声纳产生的范围分布进行分类的方法和装置。 在该方法中,利用概率模型对一组感兴趣对象中的每一个进行建模。 概率模型表示在不同取向的物体的选定特征之间的不同可能的距离序列的出现概率,其可能导致对象的范围轮廓中的后向散射的峰值。 概率模型从每个选定特征的第一概率表示中导出,用于表示定位特征的不确定性和观察范围分布中的特征的不确定性。 通过对于每个概率模型计算模型将在给定范围轮廓中产生观测到的反向散射事件之间的给定给定序列的距离的概率来实现分类。 以最大概率生成给定序列的模型识别可能产生给定范围轮廓的对象。 优选地,概率模型包括隐马尔可夫模型(HMM)。

    • When an order for goods (18) is placed via the Internet (14) for later delivery, a supplier (16) provides to a purchaser (12) via the Internet or other means a consignment unlock barcode; the purchaser prints out a copy of the consignment unlock barcode and the supplier attaches a copy (20) of a related unlock barcode to the goods (18). At the purchaser's premises is a secure container (22) with an electronic lock (32) and an external barcode reader (36). The purchaser programs the lock, by means of an exclusive master code and the supplier-generated consignment delivery code, to open when presented with the related unlock code. When a delivery driver presents the barcode (20) on the goods (18) to the reader (36), a control circuit (42) causes the electronic lock (32) to open. A second barcode reader (46) within the container (22) allows an infrared or radio receipt signal to be transmitted to a hand held infrared transceiver (52) after the securable container has been relocked.
    • 当货物订单(18)通过因特网(14)进行以后交货时,供应商(16)通过互联网或其他方式向买方(12)提供货物解锁条形码; 购买者打印出托运解锁条形码的副本,并且供应商将相关解锁条形码的副本(20)附加到货物(18)。 在购买者处所是具有电子锁(32)和外部条形码读取器(36)的安全容器(22)。 购买者通过独家主代码和供应商生成的寄售交货代码来编程锁定,以便在显示相关的解锁代码时打开。 传送驱动器将货物(18)上的条形码(20)呈现给读取器(36)时,控制电路(42)使电子锁(32)打开。 容器(22)内的第二条形码读取器(46)允许红外或无线电接收信号在安全的容器被重新锁定之后被传送到手持式红外收发器(52)。
