Abstract: A sensor control device and a sensor system are provided through which it is possible to automatically detect whether mutual interference occurs for a plurality of sensor units, and it is possible to automatically set periodic light projection timings for preventing mutual interference. A sensor control device includes a light projection control part configured to instruct a light projection operation for each of a plurality of sensor units and a light projection timing setting part configured to set periodic light projection timings when each of the sensor units is periodically operated based on results of light projection control for each of the sensor units and detection results of each of the sensor units.

Abstract: The present invention achieves a sensor that can be used more efficiently than before. The sensor (1) includes: an operator (11) that accepts a mechanical operation of a user, and generates an operation input value corresponding to the operation; a communication portion (12) that receives a communication input value; and a CPU (14) that changes sensitivity of the sensor (1) according to a later input one of the operation input value and the communication input value.

Abstract: 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.

Abstract: 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.

Abstract: A read-write processing device communicates with an RFID tag provided with a semiconductor memory to carry out read and write processes. A communication processing device executes communication processes with the RFID tag, exchanging commands and responses, and a data creating device creates safety data indicative of a margin of safety of communication based on communication results by the communication processing device. The created safety data are displayed or outputted to the outside by an output device.
