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.
摘要:
The present invention provides a lock with an authenticated open and set function, by which the lock may be opened without any bothersome operation for inserting a key to open the lock. An IC card 3 sends user identification information stored in a memory 34 to an authenticated open and set function unit 1. The authenticated open and set function unit 1 sends the user identification information to a collator 15 under the control of a controller 11 on reception of it. The collator 15 collates the user identification information sent from the IC card 3 with that stored in a memory 16. When both of the user identification information are coincided with each other, the collator 15 sends the collation signal, which is indicative of the user being authenticated, to the controller 11. The controller 11 gives a controller 17 a command to open a lock installed in a door 2. The controller 17 opens the lock based on the command by the controller 11.

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:
The refrigerator has a reader/writer for writing information in and reading information from a contactless memory medium, an information holding device for storing information read by the reader/writer, and an information display device for displaying the information stored by the information holding device. As a result of the invention of the refrigerator, the number of items such as foods that can be unconsumed and discarded because of the arrival of their consume-by dates is reduced in a refrigerator, and items such as foods stored in the refrigerator can be confirmed without opening the door.
