A configuration capable of realizing object authentication with higher accuracy is desired. A measurement system includes a shape measurement unit that performs measurement, a storage unit that stores an entire model for each work piece type, and a recognition processing unit that executes object authentication based on whether or not a three-dimensional shape measured by the shape measurement unit is consistent with any one entire model stored in the storage unit. The entire model for each work piece type is specified by a combination of a plurality of partial models and each of the plurality of partial models is correspondently given a degree of importance. The recognition processing unit determines whether or not the three-dimensional shape is consistent with any one entire model based on degrees of importance corresponding to one or more partial models included in the entire model.

Measurement system and measurement method

There has been a demand for a technique of expanding a communicable range as much as possible without increasing the time required for communication between an RF tag and a communication device. A communication device includes: a terminal electrically connected with an antenna; a transmitter electrically connected with the terminal and configured to generate a first radio signal superimposed with a predetermined command signal and transmit the first radio signal from the antenna; an amplifier electrically connected with the terminal and configured to receive from the antenna a second radio signal generated by an RF tag receiving the first radio signal; a detector configured to detect intensity of the signal having been amplified by the amplifier; and a suppressor configured to suppress the intensity of the amplified signal to be inputted into the detector such that the intensity does not exceed a predetermined upper limit.

Communication device

A tag communication apparatus conducts wireless communication with an RFID tag through a radio wave. The tag communication apparatus includes a data receiver that receives transmit data to be transmitted to the RFID tag, a data compressor that compresses at least a part of the transmit data obtained by the data receiver, and outputs the compressed data, and a transmitter that transmits the compressed data, which is compressed and output by the data compressor, to the RFID tag.

In one embodiment, a repeater relays an RF signal between an RFID (radio frequency identification) transponder having a transponder antenna, and an RFID reader having a reader antenna. The repeater includes a first antenna configured to be coupled with the reader antenna; a second antenna configured to be coupled with the transponder antenna; and a first coaxial cable which is coupled to the first and second antennas.

Repeaters for RFID systems

A read-write processing apparatus communicates with an RFID tag provided with a semiconductor memory to exchange commands and responses through antenna coils. A condition under which only a carrier wave is transmitted is set prior to a communication with the RFID tag and a level from a reception signal obtained under this condition is extracted as noise level. The extracted noise level is displayed or outputted to an output host apparatus.
