Industrial electronic badge
An industrial system includes an electronic badge worn or otherwise transported by an industrial vehicle operator. The electronic badge has a housing, a processor, and a transceiver coupled to the processor that communicates on a personal-area network with a badge communicator that is provided on an industrial vehicle when the electronic badge and the badge communicator are in range of each other. Further, an activity sensor collects activity information about the industrial vehicle operator as the industrial vehicle operator performs work tasks. The electronic badge exchanges data collected by the activity sensor with the industrial vehicle, for communication to a remote server. An electronic message is communicated to the industrial vehicle for output to a display thereon, and the electronic message defines an assigned task that is based upon previously collected data from the activity sensor.

DUAL FUNCTION STRAP FOR RESONATING ELEMENTS AND ULTRA HIGH FREQUENCY ANTENNAS
A combined EAS and RFID circuit includes an HF coil antenna, a UHF tuning loop, and an RFID chip coupled to a strap that includes a first coupling area and a second coupling area. The coil ends of the HF coil antenna are configured to capacitively and/or conductively couple to one or both of the first coupling area or second coupling area of the strap.
