摘要： In one aspect where a load or a subset of one or more tags is in motion relative to an RFID reader system, the RFID system obtains tag readings and derives tag scalar or vector motional data e.g. tag velocity, tag acceleration, and/or rate of change of tag acceleration which can be compared to known tag motional information to distinguish true tags of interest from false positives which are unavoidably also within the field of the reader system. An antenna system may also make readings during distinctive movement patterns of true tags, such as vertical or arcuate movement and utilize computed tag motional data based on the tag readings to distinguish true tags from false positives. Two components of the RFID system may communicate information on identified tags, and/or interact (e.g. by silencing tags), so as to cooperate in identifying true positive tags.

摘要翻译： 在一个方面，其中一个或多个标签的负载或子集相对于RFID读取器系统运动，RFID系统获得标签读数并导出标签标量或矢量运动数据，例如。 标签速度，标签加速度和/或标签加速度的变化率，其可以与已知标签运动信息进行比较，以将感兴趣的真实标签与不可避免地也在读取器系统的领域内的假阳性区分开来。 天线系统还可以在真实标签的特征运动模式（例如垂直或弓形运动）期间进行读数，并利用基于标签读数的计算标签运动数据来区分真实标签与假阳性。 RFID系统的两个组件可以传达关于标识的标签的信息，和/或通过沉默标签交互（例如，通过沉默标签）进行交互，以便合作识别真正的标签。
