  • Patent number: 7969253
    Abstract: A VCO includes a reference current module and a clock signal generating module. The reference current module generates a reference current according to a reference voltage. The clock signal generating module generates a clock signal according to the reference current. The reference current module utilizes the negative feed-back mechanism to keep the generated reference current at the predetermined size without being changed with the variation of the process and the bias source.

  • Patent number: 7739110
    Abstract: A method and an apparatus for multimedia data management are disclosed. The method provides an indexing and retrieval scheme for digital photos with speech annotations based on image-like patterns transformed from the recognized syllable candidates. For annotated spoken content, the recognized n-best syllable candidates are transformed into a sequence of syllable-transformed patterns. Eigen-image analysis is further adopted to extract the significant information to reduce the dimensionality. Vector quantization is applied to quantize the syllable-transformed patterns into feature vectors for indexing. The invention of indexing scheme reduces the dimensionality and noise of data, and achieves better performance of 16.26% for speech annotated photo retrieval.

  • Publication number: 20100121804
    Abstract: A personality-sensitive emotion representation system and method thereof are provided. The personality-sensitive emotion representation system comprises a behavior database, a behavior selection module and a behavior modification module. The behavior selection module selects a set of behavior parameters from the behavior database according to an emotion parameter which represents an input emotion. The behavior modification module modifies the set of behavior parameters according to the personality parameter so as to output a set of personality-sensitive behavior parameters.

  • Patent number: 7557310
    Abstract: A system and method for estimating dynamic quantities is provided. The system includes an electronic identification recognition apparatus, a weight measuring apparatus, and a computing apparatus. The electronic identification recognition apparatus can recognize an electronic identification for a corresponding item placed into the system, and the weight measuring apparatus measures a total weight of all items that it carries. The computing apparatus is coupled to the weight measuring apparatus and the electronic identification recognition apparatus, for receiving the total weight, such that the quantity of the item can be estimated and recorded by using the total weights obtained respectively before and after the item is stored or removed and a recognition result from the electronic identification recognition apparatus.
