  • Spaceborne imaging sensors require periodic calibrations using an on-board calibration device for an image quality of observation satellites. The on-board calibration device consists of a blackbody to provide uniform radiance temperatures and calibration mechanism with a function of stow and deploy to target the blackbody during the calibration. Among these devices, the calibration mechanism is required to implement a fail-safe function to prevent blocking of the main optical path when the mechanism stops at a certain position during on-orbit calibration. In addition, structural safety of the mechanical driving part of the mechanism within the launch environment must be guaranteed. In this study, we proposed a deploy/stow-type calibration mechanism that provides launch-lock and fail-safe function. The effectiveness of the functionality of the proposed mechanism was validated through functional test using engineering model.

  • Ubiquitous computer can be interfaced with many several peripheral devices for information acquisition. Users should be able to easily use these devices without considering when these devices were interfaced, how to use these devices, and interoperability issues (such as plug and play, the installation of device drivers, and so on). Further, computers and their users need an interface technology that provides five-senses information (the recognition and expressions of the user) such that multimodal interaction can be enabled. In this paper, we proposed an IEEE 1451 standard that uses a smart interface standard for interfacing devices with ubiquitous computer. IEEE 1451 describes the property information of a transducer in the transducer electronic data sheet (TEDS). Further, by using the TEDS format, the interoperability between devices can be enabled by means of the plug-and-play function; it also makes the inconvenient installations of device drivers unnecessary.
