  • Publication number: 20120136896
    Abstract: A system and a method for imputing missing values and a computer program product thereof are applicable to a data matrix. The system includes a storage unit having the data matrix and a computing device. The computing device finds complete and incomplete data transactions from the data matrix, finds at least one target data transaction approximate to each incomplete data transaction from the complete data transactions, and obtains known data at corresponding positions to compute an initial estimated data to replace unknown data. Then, a correction data transaction containing the initial estimated data is selected from the incomplete data transactions, a rough set of the selected initial estimated data is found in a manner of grouping same data into one group, and a numerical value correlated to the initial estimated data is found and used to compute an imputed data, so as to impute the imputed data into the original estimated data.

  • Patent number: 8152350
    Abstract: A sidelight-type backlight module includes a casing body, a light-guiding plate, a reflector plate, a light-emitting unit, and a reflector component. The reflector plate is disposed at a surface of the light-guiding plate, and has an extension part extending beyond a side edge of the light-guiding plate that faces toward the light-emitting unit. The reflector component has a light-reflecting face spaced apart from the reflector plate. The light-emitting unit is disposed between the extension part and the light-reflecting face. The extension part and the light-reflecting face reflect light of the light-emitting unit into the light-guiding plate so that a lamp reflector can be omitted. Preferably, the reflector component is formed integrally with the casing body.

  • Patent number: 7735398
    Abstract: A rechargeable motor-driven ratchet wrench having power-off protection of the present invention includes a motor, a rechargeable battery and a power-off protection device. When the loaded current of the motor exceeds a set default value of a reference circuit, the power-off protection device disconnects the power supply of the rechargeable battery, so as to stop the motor operation. With the circuit design of the power-off protection device, the ratchet wrench can be ensured to provide usage safety and also usage lifespan of the ratchet wrench can be extended.

  • Patent number: 7641489
    Abstract: The present invention discloses a safety plug socket, which mainly includes a sliding insulating base disposed within an outer housing. A pair of contact conducting strips is located on a bottom surface of the sliding insulating base, and conductive clips disposed internal of a pair of socket holes extend to the bottom portion of the outer housing and form folded strips. When a pair of plug terminals is correctly inserted, then the sliding insulating base is pressed down, thereby causing the lower contact conducting strips to make conductive contact with the folded strips, and causing clips on the conductive clips to make contact with the inserted plug terminals to supply power for use by an electronic product. When a plug is incorrectly inserted or metallic foreign body is inserted, then no electric conduction is realized.
