One of the approaches to solving this problem is to introduce protection functions to real-time operating system used for embedded systems. We added the access protection function of the kernel object to μITRON4.0. Protection function of embedded system is enabled by managing object in the group. This proposition outlined the protection extension of embedded software and describes the result.

However, the dynamic characteristics of the HDR have not always been clarified so far because of its scatter nature and the luck of reliable test data. In this study, new type HDR isolators are tested dynamically in several different conditions. The difference by the order of test giving the magnitude of shear strain is also discussed.

Materials for strip lines, passive devices made of strip lines, amplifiers/frequency multipliers, voltage-controlled oscillators, and phase detectors are studied by experiments. Based on these experimental results, 3.2GHz, 6.4GHz, and 12.8GHz phase-lock loops are designed and their characteristics are evaluated.

The system where the robot autonomous run from current position to the target position was constructed. The robot was setting up the omniwheel every 90 offset degrees. The kinematics of it was derived. The position and posture of the robot were acquired from the video camera set up outside. The robot controlled by positional feedback of the PID control. The color mark was put up on the robot. The position of the color mark was acquired by image data processing using the color threshold. The velocity command value was calculated from the position and posture of the robot and the target position. The value was transmitted to the robot through CUnet.
