A locational information transmission apparatus that transmits information for identifying a location is provided. The locational information transmission apparatus includes a radio communication unit that performs radio communication; a sound wave transmitting unit that transmits a sound wave including first identification information; a radio wave transmitting unit that transmits a radio wave including second identification information; and a transmission control unit that changes, depending on control information reported via the radio communication, a method of transmitting the sound wave or a method of transmitting the radio wave.
摘要:
A terminal apparatus for providing description about one or more objects arranged in a predetermined area is provided. The terminal apparatus includes a memory configured to store arrangement information indicating arrangement of the one or more objects in the predetermined area and description information associated with the one or more objects; and a processor coupled to the memory and configured to obtain area identification information for identifying the predetermined area when the terminal apparatus is located in the predetermined area, identify a positional relationship between the terminal apparatus and the one or more objects based on the arrangement information when the area identification information is obtained, and cause the terminal apparatus to describe an object of the one or more objects, in accordance with the identified positional relationship between the terminal apparatus and the one or more objects.

An information distribution system includes a sound wave transmitter, a mobile terminal, and an information distribution device. The sound wave transmitter transmits identification information to identify the sound wave transmitter. The mobile terminal receives the identification information and transmits the identification information to the information distribution device. The information distribution device is configured to transmit distribution information related to the identification information received from the mobile terminal to the mobile terminal. The information distribution device counts a number of the mobile terminal that transmits each identification information every predetermined period and identification information and transmits the distribution information to the mobile terminal that transmits the identification information in which the number of the mobile terminal reaches a predetermined number.
摘要:
An information delivery system includes a storage unit configured to store a plurality of pieces of information to be delivered to a plurality of respective intended delivery regions, a first sound-wave emitter configured to emit the pieces of information for the respective intended delivery regions toward the plurality of intended delivery regions in a form of inaudible sound waves, and a control unit configured to cause the first sound-wave emitter to emit the pieces of information stored in the storage unit.

An energy converter includes a permanent magnet and a diaphragm. The permanent magnet is fixed to a predetermined area. The diaphragm is disposed on the permanent magnet and has a coil formed of a conductor pattern.
摘要:
An output apparatus outputs an acoustic wave set with a specific frequency indicating identification information to a terminal apparatus that is to acquire the identification information from the acoustic wave. The output apparatus includes circuitry. The circuitry adjusts the specific frequency of the acoustic wave to another frequency by applying a predetermined frequency to the specific frequency, depending on a moving direction of a terminal apparatus that is to be notified of the identification information. The circuitry generates the acoustic wave of the another frequency. The circuitry outputs the generated acoustic wave of the another frequency.
