The security class or burglary resistant capability of a safe is determined by the safe's weakest parts: combinations lock, key lock, keyboard, LCD screen, card reader, fingerprint scanner, etc (referred as weak parts below). The results of an attack to the safe include opening safe door, digging holes on safe door or body, or dysfunction of the above weak parts. The corresponding consequences are: Objects deposited inside the safe are stolen or destroyed. Even if those objects stay intact, the safe owner is no longer able to operate the safe. A new design method about safe is disclosed in this invention. The new safe has no weak parts on its surface. It's obvious that weak parts are easier to destroy than safe door and body, which is why they are called weak parts. For safes without weak parts on their surface, these weak parts (in user's hand or inside safe) are not so easy to be attacked on. The GSA class or UL Certification is improved for the new safe. Users will find the new safe ...

A portable device to detect the spin of table tennis ball is invented. The device helps a user to figure out the spin of a coming table tennis ball during a table tennis game. It is composed of a camera lens to acquire sequential images, an image processing chip to extract features of the table tennis ball and to calculate the direction and strength of the spin, and a mechanism to inform the user about the spin through certain methods. One kind of the product design for the device, is to embed an integrated module into a pair of normal glasses. The integrated module consists of a mini camera lens, an image processing chip, a button battery and switch. The output of the module controls the LED lights located inside the frame of the glasses. For example of 8 points LED, the positions of 0, 3, 6, and 9 o'clock correspond to top spin, right spin, back spin, and left spin, respectively (refer FIG. 1 through FIG. 4). The centers of those position pairs correspond to top right spin, back right ...
