摘要:
A wireless communication apparatus that uses a communication protocol to transmit and receive data with a data check bit, including a received data determining section that performs a data check for received data by using the data check bit to determine whether the data is error; a received result transmitting section that, when determined to be error, discards the data and transmits a retransmission request to other wireless communication apparatus of the transmitting origin, whereas determined to be not error, transmits a message indicating that the data is normal to the other wireless communication apparatus of the transmitting origin; and a retransmission asking section that determines whether a format of the data is incorrect or normal, and when determined to be normal, passes the data to predetermined processing, whereas when determined to be incorrect, discards the data and asks the received result transmitting section to request retransmission of the data.
摘要:
The present invention provides a composition for detecting an object substance (X). This detection composition contains a gel (Y). The gel (Y) contains a colorable aqueous solution (A) that can be colored upon contact with the object substance (X), and a crosslinked polymer (B). This composition is preferably used to evaluate packaging materials.
