  • Patent number: 7918179
    Abstract: The present invention relates to an apparatus and method for a drop indicator having a magnet installed therein. The drop indicator according to the invention is used to determine whether a product has ever been dropped or impacted, either in delivery or in use, by inspecting changes in the original condition of the magnet caused by the interaction between the magnetic force and the acceleration of gravity, inertia force, and colliding force, etc. generated upon collision. Take a cell phone or a PDA, for example, changes in the indicative material of the drop indicator will help decide whether the faulty product has ever been dropped or impacted in delivery or in use, so that liability can be determined.

  • Patent number: 7621173
    Abstract: A nano-indentation ultrasonic detecting system for detecting mechanical properties of a target material. An indentation device, disposed on a surface of the target material, generates an indentation on the surface, obtaining the relation between the Young's modulus and the Poisson's ratio of the target material. An ultrasonic generator is movably disposed on the surface of the target material, generating at least two different ultrasonic signals thereon. An ultrasonic receiver is disposed on the surface of the target material and separated from the ultrasonic generator, receiving the ultrasonic signals. The result of a nano-indentation experiment are applied in the ultrasonic theory and iterated by the ultrasonic experimental data and theory, obtaining the Young's modulus of the target material. The obtained Young's modulus of the target material is substituted back in the result of the nano-indentation experiment, obtaining the Poisson's ratio of the target material.
