An ultrasonic transducer includes: a fixed electrode having corrugations on the surface; a vibrating film having an electrode layer and disposed on the surface of the fixed electrode; and a holding member which holds the fixed electrode and the vibrating film. The ultrasonic transducer is driven by applying an AC signal between the electrode layer of the vibrating film and the fixed electrode, and generates a sound pressure of at least 120 dB within a frequency range from 20 kHz to 120 kHz.

The invention provides a data output system which can control a printer in accordance with the position of a user without providing a mobile terminal and the printer with special devices, which can reduce the processing load on the mobile terminal, which can ensure the convenience of the user when using the printer, and which avoids inconvenience as a result of incorrect settings by the user. The invention can include a print control terminal that obtains mobile terminal position information from a relay station. When the distance between the mobile terminal position specified by the obtained mobile terminal position information and the printer position specified by printer position information from a storage device is less than a predetermined value, a print command and corresponding print data are transmitted to a printer PR in response to a request from a mobile terminal.

Data output system, output control terminal, program to be applied to output control terminal, and data output method

An information providing system can include a registration terminal having a guidance information registration database which stores information groups, which are correlated with reference position information. When portable terminal position information for specifying the position of a portable terminal is received together with a transmission request for the guidance information, the guidance information is automatically selected from an information group in accordance with the received transmission request on the basis of the position relationship between the reference position which is specified by the reference position information corresponding to the information group in accordance with the received transmission request, and the position which is specified by the received portable terminal position information, and the selected guidance information is transmitted to the portable terminal.

System and method for providing information to a portable terminal

The invention provides a service providing system in which it is determined whether users have use authority to utilize a service providing apparatus, such as a projector, so that only users having the use authority can utilize the service providing apparatus. The invention also provides a service providing system and a service providing apparatus. In accordance with the invention, users are allowed to have use authority to utilize the service providing apparatus through entrance into an arbitrary place, or the like so that the service providing apparatus can be conveniently utilized. A service providing system includes an instruction apparatus to give operation instructions to a projector, a virtual object management apparatus to control operations related to virtual objects, such as the setting of the virtual objects, a use authority management unit to manage determination of the presence of use authority which a system user needs in order to utilize a service, the projector to display an image on a display unit in response to the contents of the instructions issued from the system user, and a network to perform data communication among the respective apparatuses.

Service providing system and service providing device that provides a specific service in response to user authority determination based on positional relationships of virtual objects

An ultrasonic speaker including: a vibration film having a conductive layer; a pair of fixed electrodes provided oppositely to respective surfaces of the vibration film; and an ultrasonic transducer that causes the vibration film to generate sound waves by applying a DC bias voltage to the conductive layer of the vibration film while applying an alternating signal between the pair of fixed electrodes, and outputs the sound waves generated by the vibration film from two sound wave output surfaces via through-holes provided in each of the pair of fixed electrodes. The two sound wave output surfaces of the ultrasonic transducer are disposed in a direction intersecting with a sound wave emitting direction at right angles. Also, sound wave reflection plates are provided to both of the two sound wave output surfaces of the ultrasonic transducer so that the sound waves outputted from each of the two sound wave output surfaces are reflected in the sound wave emitting direction.

A display-service providing system is provided in which an image display apparatus, such as a projector, simultaneously displays a plurality of image data on a display section and the display sizes of the image data can be controlled. A display-service providing system is formed of instructing apparatuses to provide operation instructions to a projector serving as a service providing apparatus; a virtual-object management apparatus to control operations related to virtual objects, such as setting the virtual objects and giving the instructing apparatuses a right of instructing the projector; the projector to display images corresponding to the contents of instructions sent from the instructing apparatuses, on a display section; and a network to allow data communications to be performed between the above-mentioned apparatuses.

Display-service providing system and image display apparatus

The invention provides a service providing system which allows the user to easily receive service, which allows the user to receive not only information providing service but a variety of services, and which can flexibly handle a change in condition. The invention can include a virtual-object management apparatus that associates object information related to the shape and the location of a virtual object with service information and stores them, and sends the object information and the service information stored in a virtual-object management database to a digital camera in response to a transmission request sent from the digital camera.
