A control system for an industrial vehicle includes a badge communicator and an information linking device. The badge communicator has a transceiver for short range communication with electronic badges that are within in a fixed short range of the badge communicator, defining a first zone. The information linking device is programmed to execute program code. The program code extracts a current state of an operating parameter read from an industrial vehicle network bus, generates a second zone within the first zone that is defined based upon the extracted industrial vehicle operating parameter, detects a presence of an electronic badge within the first zone, determines whether the electronic badge is within the second zone, performs a first action if the detected electronic badge is not within the second zone, and performs a second action if the electronic badge is within the second zone.

This invention is applicable for changes of market requirements flexibly to reduce the lighting manufacturers' pressure and risk of inventory. Consumers can adjust the color temperature of the lamp by themselves to fit different living or working environments.

A high speed tabletop and industrial printer is disclosed with integrated high speed RFID encoding and verification at the same time. The industrial printer simultaneously prints on and electronically encodes/verifies RFID labels, tags, and/or stickers attached to a continuous web. The industrial printer comprises a lighted sensor array for indexing the printing to the RFID tags; and a cutter powered from the industrial printer for cutting the web that the RFID tags are disposed on. The industrial printer comprises two RFID reader/writers that are individually controlled. Specifically, one of the RFID reader/writers comprises the ability to electronically encode the RFID tags while the web is moving; and the second RFID reader/writer uses an additional RFID module and antenna on the printer for verifying the data encoded to the RFID tags.

Systems and methods to selectively attach and control antennas via diodes. In one embodiment, a system includes: a reader having a plurality of reader antennas of different polarizations to transmit radio frequency signals; and at least one radio frequency device. The radio frequency device includes: a plurality of tag antennas of different polarizations; a plurality of diodes coupled to the plurality of tag antennas respectively; a receiver coupled to the plurality of diodes to receive the radio frequency signals from the tag antennas when the diodes are forward biased; and a set of one or more current controllers coupled to the plurality of diodes. In a receiving mode the controllers selectively forward bias the diodes to receive the signals from the reader. In a transmitting mode the controllers selectively change the state of the tag antennas to transmit data via backscattering the radio frequency signals.

A product tagging system is provided. The product tagging system includes at least one RF backscatter transmitter configured to emit (i) a main carrier RF signal, and (ii) Radio Frequency (RF) signals on two frequencies whose summation forms a twin carrier RF signal.
