  • Publication number: 20190138770
    Abstract: A UHF RFID system is disclosed in which an RFID transponder or tag can be simultaneously powered and interrogated by multiple RFID transceivers. The architecture of the system is such that each transceiver generates its own carrier wave, with a frequency that might be equal to or different from the other units, and the interrogation data is distributed throughout a network of transceivers and modulated by each transceiver unit onto their own carrier waves. During an interrogation period, one or more of the transceivers will be configured as the master unit, generating and distributing the protocols commands. The other units can be configured as transmitters, receivers or transceivers. After each period the units may be given different roles. The proposed setup yields a system with the capability to power and interrogate RFID tags with multiple readers, without compromising the required modulation depth and protocol handling.

  • Publication number: 20190124892
    Abstract: Method and system for determining a condition of at least one pig in a pen provided with a feed unit. The pen is provided with a sensor system. For carrying out the method, a step a., step b. or a combination of steps a. and b. is possible. In a step a., with the aid of the sensor system a reaction of the at least one pig is measured. This is done when with the feed unit feed is made available in the pen to the at least one pig to determine on the basis of the measured reaction a condition of the at least one pig. In a step b., with the aid of the sensor system it is measured that the at least one pig ‘demands’ feed to determine a condition of the at least one pig.
