The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. The serpents are traversed using a defect descriptor table and one or more physical zone tables. The first and second semi-conductor components are coupled to a vacuum chamber and free space electron transmitters and receivers. Receive information related to the payload packet and to the reference packet is generated, at the receiving node. As the results, the moving orbit of the lid body can be made small, and the inner diameter of the storage space can be made small.
