  • Patent number: 10983078
    Abstract: A computer-implemented method of determining moisture content of a composite structure is provided. The method includes performing a thermal analysis calculation on the composite structure to determine a temporal surface temperature profile of the composite structure based on temporal environmental parameter profiles, wherein the surface temperature profile is determined independently of a moisture content of the composite structure. The method also includes performing a moisture content analysis calculation on the composite structure to determine a moisture content of the composite structure, wherein the moisture content analysis calculation is based on the determined temporal surface temperature profile and a thickness of the composite structure. The thermal analysis calculation is performed iteratively with a first time period and the moisture content analysis calculation is performed iteratively with a second time period that is longer than the first time period.

  • Publication number: 20160370309
    Abstract: A method of determining an allowable moisture content of a composite structure includes performing a thermal analysis on the composite structure to determine a surface temperature profile of the composite structure. The surface temperature profile is determined independently of a moisture content of the composite structure. The method also includes performing a moisture analysis on the composite structure to determine an allowable moisture content of the composite structure such that the moisture analysis is based on the determined surface temperature profile.

  • Patent number: 6970955
    Abstract: A power off method for a wireless device is proposed. A battery is installed in the wireless device as the power supply. When the power source is connected to the wireless device, an identification process is conducted between the wireless device and the wireless receiver connected to a computer. After the completion of successful identification process, the control chip within the wireless device stores a set of ID code that can be identified by the wireless receiver. In order to prevent wireless devices from being inadvertently reactivated, these devices are usually turned off during traveling. The present invention provides a power off method that terminates power to all parts of the wireless device except the control chip by a certain operation on the connect button. Therefore, an individual power switch is not required while the device can be turned off, and resume the normal operation on the next power on.
