摘要:
A frequency range of measurement is divided into a plurality of regions. For each region a test signal suitable for measurement of the region is generated independently, and the test signal is supplied to a device under test. The output of the device under test is converted by an AD converter into a digital signal, which is then subjected to fast Fourier transform. For each region the sensitivity of the AD converter is set for optimal conversion of the signal level at its input side by the converter, and then the fast Fourier transform is carried out. On the basis of the sensitivity set for one of the regions, the magnitude of the fast Fourier transform output in each of the other regions is corrected according to the sensitivities set for the other regions.

A memory card and a recording/playback device are provided that are capable of deterring a memory card manufacturer from illicitly storing a same media ID on a plurality of memory cards. A memory card (100) includes a media ID storage module unit (610) and a memory unit (120). The media ID storage module unit (610) includes a media ID storage unit (611) that stores therein a media ID that is specific to the memory card, and a certification unit (609) that generates certification information that certifies the validity of the memory card based on the media ID. The memory unit (120) includes an encrypted content storage unit (122) for storing encrypted digital content. The recording/playback device (200) includes a memory card verification unit (200) that acquires the certification information from the memory card (100), verifies the validity of the memory card (100) based on the acquired certification information, and when the verification has failed, prohibits decrypting an encrypted content or encrypting a content, and a content encryption unit (209) that, when the verification has succeeded, encrypts the digital content or decrypts the encrypted digital content.

A wireless IC device includes a substantially rectangular parallelepiped dielectric body, a metal pattern that is provided on the surface of the dielectric body via a film and functions as a radiator, and a wireless IC element coupled to feeding portions of the metal pattern. The dielectric body has a laminated structure including a folded flexible dielectric layer. Surfaces of the dielectric layer which face each other after the dielectric layer has been folded are non-bonded surfaces.

When the terminal device attempts to use a special content, which has an attribute including information distinguishing the special content from regular contents and is stored in the recording medium device, the recording medium device refers to the revocation information indicating terminal devices restricted from using the special content. When the recording medium device determines the terminal device as a terminal device to be restricted from using the special content based on the terminal identifying information of the terminal device, the usage information output unit of the recording medium device does not transmit the necessary information for using the special content to the terminal device.

A storage unit 601g of a recording medium device 600g stores a content and a revocation list. The revocation list includes a revocation identifier that is associated with the content and identifies a revoked public key certificate allocated to an apparatus related to use of the content. A controller 602g of the recording medium device 600g is provided with an acquisition unit 621g that acquires, from an apparatus 300g, an acquisition request for the content and an apparatus identifier identifying a public key certificate of the apparatus 300g; a judgment unit 622g that judges whether the apparatus identifier matches a revocation identifier; and a control unit 623g that controls to prohibit output of the content to the apparatus when the apparatus identifier and the revocation identifier match.

The terminal device 600 comprises: a read unit configured to read encrypted content and a content signature from a regular region of a recording medium device 700, and to read a converted title key from an authorized region of the recording medium device 700, the converted title key having been converted from a title key with use of a content signature generated by an authorized signature device 500; a title key reconstruction unit configured to generate a reconstructed title key by reversely converting the converted title key with use of the content signature read by the read unit; and a playback unit configured to decrypt the encrypted content with use of the reconstructed title key to obtain decrypted content, and to play back the decrypted content.
摘要:
Convenience of a control device for controlling an operating state of electrical equipment is enhanced. To achieve the enhanced convenience, a control device for controlling an operating state of electrical equipment includes a receiver, a tough-panel liquid crystal display, and an operation controller. The receiver receives power demand information transmitted from a broadcast station. The liquid crystal display receives user setting information indicating settings for operation of the electrical equipment. The operation controller controls the operating state of the electrical equipment in order to adjust power consumption of the electrical equipment, based on the power demand information received by the receiver and the user setting information input to the liquid crystal display.

A display device of an embodiment of the present invention is a display device of an active matrix type, and includes a display driver supplied with image data included in serial data by serial transmission. The serial data has a first flag for specifying a polarity of voltage of a common electrode added thereto. The display driver generates, in accordance with a timing of a serial clock, a timing signal for a horizontal period for a data signal line driver, and a timing signal for a gate signal line driver. This realizes a display device capable of easily generating, within a driver IC, a timing signal for writing the image data in pixels.
