The present invention relates to an improved treadmill which includes a massaging body suitable for massaging the soles of the feet and mounted on a base plate between a tread frame. The information associated with the captured data is repackaged, viewed, and stored in a database. Linear expansion coefficient of the disk is larger than the same of the insert. Optionally, the insertion layer may be formed within the AP2 pinned layer. The second encapsulant made by injection molding can prevent resin flash over the exposed terminals, thereby assuring electrical-connection quality of the semiconductor package. This camera allows taking pictures of blanks on-site in the plant and process them off-line to regenerate geometrical information by use of photogrammetric principles.
