  • Patent number: 8138034
    Abstract: A flexible electret transducer assembly including an electrical backplate and a membrane made of an electret material is disclosed. A plurality of spacers is formed on a surface of the electrical backplate in a longitudinal or latitudinal direction, and the spacers are used for supporting a vibrating room of the membrane. A working area of the membrane is formed between adjacent spacers, and in each of the working area, the space between the electrical backplate and the membrane is smaller than that in a conventional electrostatic speaker. The spacers between the electrical backplate and the membrane are mass produced through a stamping process. Thereby, an accurate space between the electrical backplate and the membrane can be maintained and accordingly the audio quality can be improved. In addition, a speaker including the flexible electret transducer assembly and a method for fabricating the flexible electret transducer assembly are also disclosed.

  • Publication number: 20100287395
    Abstract: A computer system for processing data in a non-operational state and processing method thereof are provided. The computer system includes a data output unit, a data source, a data processing module and a state monitor unit. The data processing module accesses and processes data from the data source, and transmits the processed data to the data output unit. The state monitor unit monitors a power supply state of the computer system to generate a state switch signal, which indicates whether the computer system is in an operational state or a non-operational state. When the state switch signal indicates that the computer system is in a non-operational state, the data source and the data processing module receives operating voltages to access and process data.

  • Patent number: 7589797
    Abstract: A transmitting-type liquid crystal display projection system including a planar light source which emits planar white beam or planar R/G/B beams in succession is provided. A first polarization filter receives the planar light source and polarizes the same to be in a first polarization state. A liquid-crystal light valve receives the polarized planar light source, and converts the first polarization state to a second polarization state having a corresponding gray level. A second polarization filter receives a light output from the liquid crystal light valve to produce a second polarization light beam. A projection unit projects the second polarization light beam onto a display plane. Using the same planar light source, a polarization beam splitting (PBS) device with a refection-type liquid crystal light valve can be used to achieve the reflection-type projection system.
