    Abstract: Technologies are generally described for distance determination between two or more RFID tags based on a minimum detectable signal. In some examples, a first RFID tag may establish communication with a second RFID tag, and modulate an irradiating electromagnetic field to generate backscatter signals for sequential transmission to the second RFID tag. A depth of amplitude modulation of each transmitted signal may be progressively reduced until the second RFID tag can no longer detect the modulation. The particular distance between the first and second RFID tags may then be determined based on a minimum detectable signal by the second RFID tag, which may be identified as a last transmitted signal detected by the second RFID tag. In some embodiments, distance determination between two or more RFID tags as described above may be implemented for robotic sensing, assembly systems, security, and wearable technology to track motion and/or position of objects.

    Abstract: In some examples, a device may include a communication interface configured to exchange signals with another device, and a computing component configured to autonomously calculate a centroid of a plurality of devices of which the device is a part, based at least in part on relative distances between the device and others of the plurality of devices and relative distances among the others of the plurality of devices, and autonomously establish the centroid as a shared secret.

    Abstract translation: 一般来说，技术基于最小可检测信号来描述两个或多个RFID标签之间的距离确定。 在一些示例中，第一RFID标签可以建立与第二RFID标签的通信，并且调制照射电磁场以产生用于顺序传输到第二RFID标签的反向散射信号。 每个发射信号的幅度调制深度可以逐渐减小，直到第二RFID标签不再能够检测到调制。 然后可以基于第二RFID标签的最小可检测信号来确定第一和第二RFID标签之间的特定距离，其可以被识别为由第二RFID标签检测到的最后发送信号。 在一些实施例中，可以实现如上所述的两个或更多个RFID标签之间的距离确定用于机器人感测，组装系统，安全性和可穿戴技术以跟踪物体的运动和/或位置。
