Shaft-locking bushing

The ETP "Express" Model E keyless locking device uses a double-walled sleeve, piston, and one radial tightening screw to secure drive-component hubs to shafts. Tightening the setscrew expands the sleeve, forming a continuous, tight connection between shaft and hub. The design reportedly minimizes shaft and mounted power-transmission component wear typical of keyway- and taper-type position-locking mechanisms. Available in 15-, 20-, 25-, 30-, 35-, 40-, 45-, and 50-mm shaft sizes, the keyless bushing locks into position sprockets, gears, pulleys, couplings, and other power-transmission components.

Laurie Ann Toupin on Renting Software, Leveraging the Internet

The Internet was perhaps the biggest news at the Computer Technology Solutions Show in Detroit as companies struggled to find ways to leverage the capabilities of cyberspace. MSC.Software announced on-line onDemand Licensing where engineers can basically rent FEA software from MSC, including MSC/NASTRAN and MSC/Patran by the week or month. The 24-hour-a-day, 7-day-a-week service is available from Engineering-e.com. SolidWorks announced eDrawings, a compressed electronic drawing file that enables users to create, view, send, and receive mechanical design drawings via email. Each eDrawing file includes a self-contained viewer, so recipients can start using the drawing information immediately whether or not they are a SolidWorks user. This will be free for a limited time at the SolidWorks website. Engineering Animation Inc. and Hewlett-Packard are also getting into the act. Together, the companies are offering a portal for the manufacturing community through e-vis.com. It offers a secure Internet collaboration where project members can capture the decision making rationale, track issues, hold real-time design reviews, search, and update the team.

Simulation interoperability

Micro Saint Version 3.1, a general purpose discrete-event simulation software, now can communicate and exchange information with other software applications. COM Services allows users to pass variable values into and out of Micro Saint during model executions, and control the event queue that allows users to insert scenario events into the queue at specified times. Model control allows users to pause, halt, and abort the model through parsed expressions. Command line capabilities allow users to start, stop, and continue the model as well as the capability of sending messages to the user when a model has ended or if errors have occurred. With COM Services, a user can begin the process of setting up interoperability using Visual Basic, C++, the High Level Architecture RTI or some other programming language as the middleware between Micro Saint and another application.

CAD-to-web solution

E-Com CAD, a 3D on-line product configurator, dynamically generates CAD models based on specific user inputs. From a web-based entry form, users answer a series of questions about their specific applications. From this input, a properly sized part is selected and the software generates a corresponding 3D model. The model can then be rotated, cross-sectioned, and zoomed in or out live on the Web, or can be downloaded to the user's computer for insertion into the engineer's design drawing. The current program generates 3D models in CATIA, Unigraphics, SolidWorks, or IGS format; 2D formats include .DXF or .DWG.

Precision measurement chips

This chip was designed to make precision measurements at a sample rate of up to 4kHz, for applications such as process control and medical instrumentation. The Crystal(R) CS553x uses the Crystal MultiPathTM amplifier core, an architecture that enables the devices to operate at a very low noise level6nV/=Hz at 0.1 Hz and very high resolution up to 23 bits. By integrating the multiplexer, amplifier, and analog-to-digital converter (ADC) on a single chip, the devices simplify analog front-end design for the system engineer.
