Claris CAD Claris CAD Claris CAD was a two-dimensional computer-aided design program for Apple Inc. Macintosh. Claris CAD was developed in 1988 by Claris Corporation in a joint effort with Craig S. Young of Computer Aided Systems for Engineering (CASE). It was based on MacDraw II and Young's earlier CAD application, "EZ-Draft". Version 1 was released in 1989 for Macintosh computers running System Software 6 or later. The initial releases were plagued with bugs, especially with the bundled plotter driver. Development halted in June 1991 with the release of version 2.0.3. Currently, Claris CAD can be run on older Macintoshes using the
Computer-assisted orthopedic surgery Computer-assisted orthopedic surgery Computer-assisted orthopedic surgery or computer-assisted orthopaedic surgery (sometimes abbreviated as CAOS) is a discipline where computer technology is applied pre-, intra- and/or post-operatively to improve the outcome of orthopedic surgical procedures. Although records show that it has been implemented since the 1990s, CAOS is still an active research discipline which brings together orthopedic practitioners with traditionally technical disciplines, such as engineering, computer science and robotics. The principal idea behind CAOS is that operative outcomes will be improved through the use of computer technology. Taking the example of joint replacement, the task of the surgeon is to integrate
