  • Patent number: 8864927
    Abstract: A method for making a carbon nanotube film is provided. First, a carbon nanotube array is formed on a grown substrate. The carbon nanotube array is pressed with a first substrate using a first pressing force to form a carbon nanotube film precursor. Then the first substrate and the grown substrate are separated, and the carbon nanotube film precursor is transferred onto the first substrate. After that, the carbon nanotube film precursor is pressed using a second substrate with a second pressing force. Lastly, the first substrate and the second substrate is separated, with part of the carbon nanotube precursor transferred to the second substrate to form the carbon nanotube film.

  • Publication number: 20140310552
    Abstract: Current computer systems support sleep states such as sleep state S3 and sleep state S4. A system in sleep state S3 utilizes more power than one in sleep state S4, however, a system in sleep state S3 can resume function substantially faster than a system in sleep state S4. An idle system is often put into sleep state S3 rather than sleep state S4 because of the shorter resume time even though sleep state S3 utilizes more power. Embodiments include a reduced-power sleep state S3 that uses less power than sleep state S3 yet resumes function faster than sleep state S4. Embodiments reduce the power consumed by compressing and consolidating system context to fewer memory modules, and powering down unused memory modules. Embodiments thus avoid storing system content to non-volatile memory. Embodiments include waking the system by restoring system context in the reverse order to respective memory modules.
