Abstract: A vehicle interior classification system and method in accordance with the present invention determines a classification relating to the interior of the vehicle, such as the occupancy status of a vehicle seat or the state of alertness of a vehicle driver, from one or more images of an appropriate portion of the interior of the vehicle acquired with an image capture device. The acquired images are preferably processed to limit the dynamic range of the images to obtain a resultant image which can comprise one or more regions of interest which are less than the total field of view of the image capture device. The resultant images are processed to extract information about features in the image and, in one embodiment, this processing is achieved with a two-dimensional complex discrete wavelet transform which produces a set of coefficients corresponding to the presence and/or location of the features in the resultant image.

Abstract: A platform comprising: a base; a first platform unit rotatably mounted to the base and being rotatable about a first axis relative to the base; a second platform unit rotatably mounted to the first platform unit and be rotatable about a second axis relative to the first platform unit; and a flexible transmitting device connected between the base and the first platform unit and/or the first platform unit and the second platform unit for transmitting power and/or data. The flexible transmitting device is arranged to wind about the first axis when the first platform unit is rotated about the first axis and/or wind about the second axis when the second platform unit is rotated about the second axis.

Abstract: A crawling system crawls a web site initially in a pattern detection phase and subsequently in a pattern usage phase. The pattern detection phase attempts to identify patterns of references to pages that contain informational content of interest and patterns of references to pages that contain little informational content of interest. During the pattern usage phase, the crawling system crawls the web site. When the crawling system encounters a reference contained on an accessed page, the crawling system determines whether the reference matches a reference pattern. If the reference matches a reference pattern associated with pages that contain informational content of interest, the crawling system accesses the referenced page. If, however, the reference matches a reference pattern of pages with little informational content, then the crawling system discards that reference without accessing the referenced page.

Abstract: An application-based data encryption method implemented in an operating system. When receiving system calls for writing data opened by an application, the operating system encrypts the data utilizing an encryption key. When receiving system calls for reading data requested by the application, the operating system decrypts the data utilizing a decryption key. The encryption key and the decryption key may be the same key or two different keys.

Abstract: A modulator for an optical transceiver is disclosed. The modulator has two quarter-wave stack mirrors composed of alternating dielectric layers with an optically absorbing layer sandwiched in between to form the vertical resonant cavity. The optically absorbing layer is made of semiconductor nanocrystals embedded in a dialectic material. The device is configured to operate near the saturation point of the absorption layer. By adjusting the biasing voltage across the absorption layer, the saturation threshold of the semiconductor nanocrystals is altered, resulting in the overall reflectivity of the resonant cavity to vary. The modulator is configured to be fabricated as the extension of the backend process of Si CMOS.

Abstract: The invention relates to a new and improved heavy oil hydrocracking process using a multimetallic liquid catalyst in a slurry-bed reactor, particularly an improvement of lightweight treatment of heavy oil in the petroleum processing technology. According to the present invention, a slurry-bed hydrocracking reactor and a highly dispersed multimetallic liquid catalyst are mainly applied during the process. A fixed-bed hydrotreating reactor is also used on line to enhance lightweight oil yield from heavy oil under normal pressure.
