We present a new haptic augmented reality system that modulates the perceived stiffness of a real object by changing the perceived material with vibratory subtraction and addition. Our system consists of a stick with a vibrotactile actuator and a pad with an elastic sheet. When a user taps the pad, the innate vibration resulting from the tapping is absorbed by the elastic surface. Simultaneousl...

This paper describes research that explored the issues likely to be encountered when an agile process is introduced into a traditional environment. The methodology used considers strategic, cultural, and process integration issues in the implementation of advanced technologies. The methodology is used to define upstream/downstream process integration issues and impact for the replacement of fix...

THE BIOCAPSULE AND ASSOCIATED E Q U I P M E N T Compared wit'h the capsule for BioFlight 1 the new .capsule was constmeted from a somewhat heavier aluminum alloy sheet to avoid the use of reinforcing ribs. Two access ports located ,on opposite sides of the capsule were provided to facilitate placement of equipment inside the c~psule. An additional small opening was located near fhe one used for...

In recent years, the use of aluminum alloy has tended to increase for building lightweight automobiles to reduce their automotive weight, which is helpful to save energy and protect the environment. In order to join aluminum alloy, a flat-clinching process combined with material forming technology was investigated to join aluminum alloy sheets using an experimental and a numerical method. Al106...

Thin sheets of aluminum alloys are widely used for the packaging pharmaceutical and cosmetic products in food industry; however they present critical issues during forming process. The blow process, which is glass plastics industries hot metal sheets, allows solving problems related to lubrication small tolerance ranges tools required by well-known deep drawing process form a thin sheet. In thi...
