    • A data reading system is mountable onto a material transport device having a first section, a primary power supply and a second section movable with respect to the first section. The data reading system comprises a data reader disposed on the second section of the material transport device, the data reader comprising a power source and an induction power receiving unit. The data reading system also comprises an induction power transmission unit disposed on the first section of the material transport device and connected to the primary power supply of the material transport device. The induction power receiving unit is located proximate the induction power transmission unit when the second section is disposed in a given position with respect to the first section, whereby the induction power transmission unit transmits power to the induction power receiving unit for charging the power source of the data reader.

    • A preferred embodiment is directed to a method of RFID power ramping for tag singulation that includes activating the trigger control of an RFID reader for engaging power to begin reading RFID tags. A user may take a first reading at a low power level of a volume around the RFID reader establishing a first read volume. If the user does not detect a particular RFID tag, the user may then increase the transmitting power from the RFID reader to a second higher power level obtaining a second reading of RFID tags in a second read volume. The user may once again increase the transmitting power from the RFID reader to a third higher power level obtaining a third reading of RFID tags in a third reading volume. Increasing the RFID transmitting power is repeated until there is a final read volume where the operator reads and recognizes the detected RFID tag. The final step includes deactivating the trigger control of the RFID reader after reading the desired RFID tag.
    • 优选实施例涉及用于标签分割的RFID功率斜坡的方法,其包括激活RFID读取器的触发控制以接合电力以开始读取RFID标签。 用户可以在建立第一读取体积的RFID读取器周围的体积的低功率水平进行第一读取。 如果用户没有检测到特定的RFID标签,则用户可以将来自RFID读取器的发射功率增加到第二较高功率水平,从而获得在第二读取体积中的RFID标签的第二读取。 用户可以再次将来自RFID读取器的发射功率增加到第三较高功率水平,从而获得第三读取体积中的RFID标签的第三读数。 重复增加RFID发射功率,直到存在操作者读取并识别检测到的RFID标签的最终读取体积。 最后一步包括在阅读所需的RFID标签之后停用RFID阅读器的触发控制。
