  • Patent number: 7359473
    Abstract: In a communication device, a counter counts a reference clock CLK1 at each edge of a data signal, and a clock generator generates a reception clock corresponding to the count value of the counter. When there is a frequency lag between the reception clock and the frequency of the transmission clock at a communication partner side, the count value when an edge detection signal is at a H-level is deviated from the count value. This deviation reflects decode signals DS1 to DS3, and phase delay or phase advance is detected on the basis of a signal P1 or P2. At this time, the estimated value of the next edge period is increased/reduced by only “1”. When the deviation of the count value occurs sequentially, a frequency excessively-small state or excessively-large state is detected on the basis of the signal F1 or F2. At this time, the estimated count value of the next edge period is increased/reduced by only “2”.

  • Publication number: 20080058444
    Abstract: A polymerization curable composition prepared by blending specific amounts of a photochromic compound and a specific light stabilizer such as bis(1,2,2,6,6-pentamethyl-4-piperidyl)sebacate with monomer components including a specific bifunctional monomer having a structure that two phenylene groups are bonded together by a specific group, such as 2,2-bis(4-methacryloyloxypolyethoxyphenyl)propane, a polyfunctional polymerizable monomer having a functionality of 3 or more such as trimethylolpropane trimethacrylate, and a monomer other than these in a specific ratio. The polymerization curable composition provides a cured product having excellent photochromic properties such as fast fading rate and sufficiently high drilling strength that allows for its use in rimless spectacles and has high long-term storage stability.

  • Patent number: 7290025
    Abstract: A calculation speed of division carried out in a computer is increased. Partitioning means partitions a dividend y that is a 32-bit digital datum at every 8 bits from the least significant bit to generate four bit blocks y(1) to y(4). For the respective bit blocks, table reference means finds solutions z(1) to z(4) obtained by dividing, by a divisor x, values expressed by replacing the bits other than the bits in each bit block with 0, while referring to tables (1) to (4) stored in storage means. Addition means adds all the solutions z(1) to z(4) to find the solution z.

  • Patent number: 7149324
    Abstract: The use of the undefined low-order four bits of an 8-bit watermark is defined and, when contents are reproduced, a predetermined operation is performed according to the information stored in the low-order four bits. That is, a watermark is added to an original image to create an image with the watermark inserted. When the contents are reproduced, the watermark is detected in the image and, based on the information stored in the low-order four bits of the detected watermark, a predetermined operation, for example, access to a web site on the Internet, is performed.

  • Patent number: 7146501
    Abstract: In encoder side, an electronic watermark generating device generates an electronic watermark which contains a encryption key. An electronic watermark inserting device inserts the electronic watermark containing the encryption key into a first portion of data. An encrypting device encrypts a second portion of the data with the encryption key. The first portion into which the watermark containing the encryption key has been inserted and the second portion which has been encrypted with the encryption key are combined by a switch and thereafter recorded on a record medium or transmitted to a network. In decoder side, the watermark containing the encryption key is extracted from the first portion and the encryption key is extracted from the watermark. The second portion is decrypted with the extracted encryption key.

  • Publication number: 20060267738
    Abstract: A semiconductor integrated circuit includes a sampling unit, a delay unit, a first operating unit and a second operating unit. The sampling unit samples an input signal supplied from an external circuit in synchronization with a clock signal, and outputs the sampled input signal as a first signal. The delay unit delays the first signal in synchronization with the clock signal, and outputs the delayed first signal as a second signal. The first operating unit operates whether a signal level of the input signal is sustained equal to or longer than a predetermined period based on the first and second signals, and outputs an output signal in synchronization with the clock signal when the signal level of the input signal is sustained equal to or longer than the predetermined period. A signal level of the output signal is sustained equal to or longer than the predetermined period. The second operating unit asynchronously controls the sampling unit based on the input signal and the output signal.

  • Patent number: 7125086
    Abstract: In a vehicle dynamics control (VDC) system for a four-wheel-drive vehicle employing a brake control system regulating braking forces applied to road wheels independently of each other and a differential mechanism controlling a differential motion between front and rear wheel axles, a VDC controller controls a braking force of each road wheel depending on whether the vehicle is in oversteering or understeering. The VDC controller includes a braking-force compensation section that compensates for a braking force of at least one of a first wheel, which is subjected to vehicle dynamics control, and a second wheel to which a transferred braking force is transferred from the first wheel through the differential mechanism, to reduce a braking force of the second wheel and to prevent the braking force of the second wheel from exceeding a lateral grip limit of the second wheel during the vehicle dynamics control.

  • Patent number: 7092546
    Abstract: A watermarking system allowing both sufficiently high quality of watermarked moving pictures and enhanced ease of watermark detection is disclosed. A watermark level of a watermark to be embedded into a picture of data is changed depending on the picture type of a selected block of frequency component data, and then a watermark having the watermark level is inserted into the selected block of frequency component data. Therefore, a moving-picture can be effectively embedded with a digital watermark without substantially reducing the quality of image and the digital watermark can be detected reliably. A relative proportion of watermark levels of I-picture, B-picture, and P-picture is preferably set to 10:7:5.
