    • An imaging module for imaging, and a reader for and a method of electro-optically reading a target, include a support, an imaging assembly including a solid-state imager having an array of image sensors on the support for capturing return light over a field of view at a range of working distances from the target along a folded imaging path, and an illuminating assembly on the support for directing illumination light along a folded illuminating path having a length longer than the folded imaging path to uniformly illuminate the target with the illumination light. The longer length of the folded illuminating path enables the illuminating assembly to illuminate the target with more of the illumination light, and also enables the imaging assembly to capture more of the return light for increased imaging/reading performance.
    • 用于成像的成像模块和用于电光学读取目标的读取器和读取器的方法包括支撑件,成像组件,其包括固态成像器,所述固态成像器具有用于在场上捕获返回光的支撑件上的图像传感器阵列 在沿着折叠成像路径的目标的工作距离范围内的视角以及在所述支撑件上的照明组件,用于沿着具有比折叠成像路径长的长度的折叠照明路径引导照明光,以均匀地照亮所述目标的照明 光。 折叠照明路径的较长的长度使得照明组件能够以更多的照明光照亮目标,并且还使成像组件能够捕获更多的返回光以增加成像/读取性能。

    • Methods, systems, and apparatuses for tracking and monitoring tagged objects in an RFID environment is described. By varying RFID reader antenna output power levels and detecting RFID devices in the vicinity, data about position and orientation of the RFID devices can be gathered. This gathered data is used to correlate with pre-stored data about RFID devices' position and orientation. Such a correlation then can be used to infer data about neighboring RFID devices based upon data stored in the database. Such an inferential technique also results in a faster analysis of position and orientation data of RFID devices, and also leads to faster tracking of RFID enabled devices. Unnecessary reads and high power operations of the RFID reader are also avoided.
    • 描述了用于跟踪和监视RFID环境中的标签对象的方法,系统和装置。 通过改变RFID读取器天线输出功率水平和检测附近的RFID设备,可以收集关于RFID设备的位置和取向的数据。 该收集的数据用于与RFID设备的位置和方向的预存数据相关联。 然后可以使用这样的相关性来基于存储在数据库中的数据来推断关于相邻RFID设备的数据。 这种推理技术还可以更快地分析RFID设备的位置和方向数据,并且还可以更快地跟踪RFID设备。 也避免了RFID阅读器的不必要的读取和大功率操作。
