20080273879 | Optical Transmission System and Method for Compensating Wavelength Dispersion of Main Signal By Multiplexing Dispersion-Free Control Signal - At the transmit end of an optical transmission link, a main signal and a control signal are multiplexed into an optical multiplex signal and forwarded to the link. The frequency of the control signal is much lower than the frequency of the main signal so that the control signal is not affected by the wavelength dispersion effect of the transmission link. A the receive end of the link, the optical multiplex signal is demultiplexed, recovering the main signal and the control signal. An amount of compensation necessary to compensate for the wavelength dispersion of the recovered main signal is detected and used in combination with the dispersion-free control signal to compensate for the wavelength dispersion of the optical main signal. The main signal and the control signal may either be frequency division multiplexed or wavelength division multiplexed into the optical multiplex signal. | 11-06-2008 |

20100036792 | Image Processing Apparatus, Image Processing Method, and Computer Program - An information processing apparatus includes information input units, an event detecting unit, and an information-integration processing unit. Observed values including user identification data are obtained based on image and sound information from the information input units such as a camera and a microphone. Target data set with plural user confidence factors is updated and user identification is then performed. The user identification information in the observed values is used for updating the simultaneous occurrence probability of candidate data by which targets are corresponded with respective users. The updated value of such probability is used for calculating the user confidence factors corresponding to the targets. | 02-11-2010 |
