摘要： An information access system comprises a reader/writer for continually transmitting an ID request signal at a first frequency and being continuously ready to receive an RF signal at a second frequency, and an active contactless information storage device having a receiver for sensing a carrier of an RF signal at the first frequency, and a transmitter for transmitting a response signal at the second frequency when the ID request signal is received. When the receiver senses a carrier of an RF signal at the first frequency in a particular predetermined period, the receiver receives further the ID request signal, and, in response to the ID request signal, the transmitter transmits a response signal at the second frequency carrying an ID of the storage device stored. In the carrier sensing, the controller causes the receiver to be in an active state and the transmitter to be in an inactive state in the predetermined periods. When the receiver attempts to sense a carrier of the RF signal at the first frequency in a particular predetermined period but detects no carrier, the controller controls the receiver and the transmitter to maintain the inactive state during a sleep period between the particular predetermined period and the subsequent predetermined period.

摘要： In an information access system, a reader/writer device encrypts, with a first encryption key, an information request and a second encryption key to thereby generate first encrypted data, and encrypts the information request with the second encryption key to thereby generate second encrypted data, and transmits cyclically an information request signal that alternately carries the first encrypted data and the second encrypted data. An active contactless information storage device receives the information request signal and decrypts the encrypted data carried by the information request signal with one encryption key stored in its memory. When the second encryption key different from the one encryption key is contained in the decrypted data, the information storage device rewrites the one encryption key with the second encryption key.

摘要： In an information access system, an active contactless information storage device senses a carrier of an RF signal at a first frequency in first predetermined periods occurring in a predetermined cycle and senses a carrier of an RF signal at a second frequency in second predetermined periods occurring in the predetermined cycle. When the storage device senses and detects a carrier of an RF signal at one of the first and second frequencies in a particular predetermined period, it receives further an ID request signal, and, in response to the ID request signal, transmits a response signal at a corresponding one of the third and fourth frequencies that carries an ID of the active contactless information storage device. This reduces possible interference between reader/writer devices for communicating with the information storage device.

摘要： In an information access system, an active-type contactless information storage device senses a carrier of an RF signal at a first frequency in time periods for carrier sensing occurring in a predetermined carrier sensing cycle period, and then in response to detection of a carrier of an RF signal at the first frequency, further receives the information request signal, while it also transmits the tag information signal at a second frequency carrying information in time periods for tag information transmission occurring in a predetermined tag information transmitting cycle period. A reader/writer device cyclically transmits an information request signal carrying values of the predetermined carrier sensing cycle period and the predetermined tag information transmitting cycle period, at a first frequency during a predetermined period of time for information request transmission, and in response to reception of a tag information signal at the second frequency, reproduces and compares received tag information with a list of tag information. In response to reception of the information request signal, the active-type contactless information storage device reproduces and sets the values of the two predetermined cycle periods into its respective timers. Thus the active-type contactless information storage device reduces its power consumption.
