20090251525 | Method of Forming Visual Image on Optical Disk by Laser Beam - A method is designed for forming a visual image having a specified shape on a surface of an optical disk by using an optical writing process of irradiating a laser beam onto the surface of the optical disk to form pits. The optical disk is normally capable of recording information on the surface thereof by the optical writing process. The method is carried out by the steps of acquiring image formation information associated to a visual image to be formed, forming the visual image on the surface of the optical disk based on the acquired image formation information by using the optical writing process, and recording the image formation information together with the formed visual image on the surface of the same optical disk. The image formation information contains start address information specifying a position of the surface of the optical disk to start the optical writing process for forming the visual image, stop address information specifying another position to stop the optical writing process, and pattern information specifying a pattern of irradiating the laser beam during the optical writing process. | 10-08-2009 |
20100115262 | Wireless Network System and Wireless Communicaton Method - A wireless network system includes a user device, a client and an access point. In the wireless network system, a wireless network mode of the client is started in an AdHoc mode in response to specific operation, a wireless network mode of the user device is switched to an AdHoc mode when it is detected that the wireless network mode of the client is started in the AdHoc mode. Then, infrastructure network information including a network name and an encryption key for setting the wireless network communication in the infrastructure mode is transmitted from the user device to the client, and the wireless network mode of the client is switched to the infrastructure mode on the basis of the infrastructure network information. | 05-06-2010 |
20100174391 | Remote Control System and Relay Unit - A remote control system includes a commander, a device to be controlled, and a relay unit. The commander transmits a start command and an end command, and a continuation command at intervals of first specific time after transmission of the start command until the end command is transmitted. The relay unit includes a control unit that causes a control signal transmission unit to start transmitting the control signal in response to receipt of the start command and that causes the control signal transmission unit to stop transmitting the control signal in response to receipt of the end command. The control unit causes the control signal transmission unit to stop transmitting the control signal when the next command is not received even after elapse of a second specific time since the command is received, the second specific time being longer than the first specific time. | 07-08-2010 |
20150264502 | Audio Signal Processing Device, Position Information Acquisition Device, and Audio Signal Processing System - An audio signal processing device includes a calculator for generating a plurality of audio signals to be given respectively to a plurality of loudspeakers based on an audio signal corresponding to a virtual sound source having position information. The calculator calculates, with respect to each loudspeaker, a distance between each of the plurality of loudspeakers and the virtual sound source on the basis of position information indicating a position of the virtual sound source and loudspeaker position information indicating positions of the plurality of loudspeakers, and calculates an audio signal corresponding to the virtual sound source to be supplied to each of the plurality of loudspeakers on the basis of the distance. | 09-17-2015 |
20160066112 | Audio Device, Audio System, and Method - An audio device includes: an acquisition unit that acquires first information indicating an arrangement direction of a first loudspeaker, the first information being measured by a terminal device in a state with the terminal device oriented toward the first loudspeaker; and a calculation unit that calculates a position of the first loudspeaker, at least based on a distance from a reference position to the first loudspeaker, and the first information. | 03-03-2016 |
20160112797 | ACOUSTIC SYSTEM, OUTPUT DEVICE, AND ACOUSTIC SYSTEM CONTROL METHOD - An acoustic system includes a supply device, which is connected to a network and configured to supply an acoustic signal to the network, and at least one output device configured to output a sound based on the acoustic signal supplied from the supply device via the network. Also, the acoustic system includes a control unit, which is provided to the at least one output device on a one-to-one basis, and configured to control necessity/non-necessity of outputting the acoustic signal to an associated one of the at least one output device, based on frequency characteristics of the acoustic signal. | 04-21-2016 |
20160112799 | ACOUSTIC SYSTEM, ACOUSTIC SYSTEM CONTROL DEVICE, AND ACOUSTIC SYSTEM CONTROL METHOD - An acoustic system includes a supply device, which is connected to a network and configured to supply an acoustic signal to the network and at least one output device configured to output a sound that is based on the acoustic signal supplied from the supply device via the network. The acoustic system also includes a detection unit configured to detect whether the at least one output device is in a state of being capable of outputting the sound and a control device configured to control, based on a result of the detection by the detection unit, to which output device the acoustic signal is to be supplied out of the at least one output device. | 04-21-2016 |
20160112800 | Acoustic System, Acoustic System Control Device, and Acoustic System Control Method - An acoustic system includes a supply device, which is connected to a network and configured to supply an acoustic signal to the network. The acoustic system also includes a plurality of output devices each configured to output a sound based on the acoustic signal supplied from the supply device via the network and a control device configured to control, based on a frequency of the acoustic signal, to which output device the acoustic signal is to be supplied out of the plurality of output devices. | 04-21-2016 |
