    • Systems, methods and computer program products for tracking objects in an area of interest are described. According to an embodiment, an object is tracked as follows. First position information relating to the object is received from a first sensor and translated to a coordinate system of a map. The object is displayed on the map in accordance with the translated first position information. Second position information relating to the object is received from a second sensor, where the second sensor is based on a second positioning technology different from the first positioning technology. The second position information is translated to the coordinate system of the map, and the object is displayed on the map in accordance with the translated second position information. In an embodiment, other information relating to the object is also received from sensors.
    • 描述用于跟踪感兴趣区域中的对象的系统,方法和计算机程序产品。 根据实施例,如下追踪对象。 从第一传感器接收与物体有关的第一位置信息,并将其转换为地图的坐标系。 该对象根据翻译的第一位置信息显示在地图上。 从第二传感器接收与物体相关的第二位置信息,其中第二传感器基于与第一定位技术不同的第二定位技术。 第二位置信息被转换为地图的坐标系,并且根据翻译的第二位置信息将对象显示在地图上。 在一个实施例中,还从传感器接收与该对象有关的其它信息。

    • Systems, methods and computer program products for the centralized control of radio frequency identification (RFID) readers are described herein. An input event control embodiment operates by receiving a signal from a non-RFID input device and commanding an RFID reader associated with the non-RFID input device to begin reading. According to an alternative time coordination embodiment, non-overlapping time slots are assigned to a plurality of RFID readers, and the RFID readers read only during their respective non-overlapping time slots. According to an alternative combined input event control/time coordination embodiment, non-overlapping time slots are assigned to a plurality of RFID readers. A signal from a non-RFID input device is received, and an RFID reader associated with the non-RFID input device is commanded to begin reading. However, such RFID reader only begins to read at the beginning of its next assigned time slot.
    • 本文描述了用于射频识别(RFID)读取器的集中控制的系统,方法和计算机程序产品。 输入事件控制实施例通过从非RFID输入设备接收信号并且命令与非RFID输入设备相关联的RFID读取器开始读取而进行操作。 根据替代的时间协调实施例,非重叠时隙被分配给多个RFID读取器,并且RFID读取器仅在它们各自的非重叠时隙期间读取。 根据替代组合输入事件控制/时间协调实施例,非重叠时隙被分配给多个RFID读取器。 接收来自非RFID输入设备的信号,并且命令与非RFID输入设备相关联的RFID读取器开始读取。 然而,这样的RFID读取器仅在其下一个分配的时隙的开始处开始读取。
