摘要:
Within a building, wireless communications can be carried out by using signals at millimeter wavelengths. The building is, for instance, arranged by employing: a first antenna mounted on the side of one surface of a door or a wall, for sensing a signal having a millimeter wavelength; a second antenna mounted on the side of the other surface of the door or the wall, for radiating a signal having a millimeter wavelength; a first receiver for receiving the millimeter-wave signal sensed by the first antenna, and for converting the received millimeter-wave signal into an electric signal; and a first transmitter for converting the electric signal which is received and converted by the first receiver into the millimeter-wave signal and for transmitting the converted millimeter-wave signal via the second antenna.

For transmitting transmission data generated by a transmission data generator of a communication terminal device, a packet unit determining unit 17 determines a packet unit for a lowest data communication rate for the transmission of the transmission data, among packet units (packet sizes) that can be recognized by a destination communication terminal device and that can be transmitted from the communication terminal device. A packet generator 18 packetizes the transmission data according to the packet unit determined by the packet unit determining unit 17, and transmits the packetized transmission data to the destination communication terminal device.

A browser apparatus, a server apparatus, a computer-readable medium, a search system and a search method are provided which enable a user to readily execute a search on a network particularly even if the user is a computer illiterate. In other words, for instance, the browser apparatus, the server apparatus, the computer-readable medium, the search system and the search method of the present invention perform as follows: searching sites and/or pages on the network; obtaining the values of access counters in sites and/or pages found in the search; and arranging the sites and/or the pages found in the search in accordance with the obtained access counter values so that the site or the page having the larger access counter value is ranked higher, and for outputting the information on the arrangement of the sites and/or pages as the result of the search.
摘要:
A method of efficiently collecting a charge for the payment of money for an article of merchandise that are purchased is used in a charge collection system having a contactless storage medium in an article tag which has recorded product information therein, a contactless storage medium in a customer terminal which has recorded customer ID information therein, and a charging device in a store. The method comprises the steps of reading the product information from the contactless storage medium in the article tag into the charging device (step 71), calculating a total amount of money with the charging device based on the read product information (step 72), settling the payment of the calculated total amount of money with the charging device by receiving corresponding cash or reading the customer ID information from the contactless storage medium in the customer terminal (steps 74-78), and recording information of the settled payment in the contactless storage medium in the article tag (steps 79, 80).
摘要:
There is provided a tag IC that radio waves transmitted from the tag IC is intensified, so that information stored in the tag IC can be read even if the distance between the tag IC and a reader is increased. The tag IC comprises an antenna that receives/transmits signals from/to the reader with AC electromagnetic energy, an IC chip that decodes received data from the reader, calculates transmitting data based on stored data, and transmits data, and a solar cell that directly converts optical energy to electrical energy to supply power to the IC chip.
