ENSC494-01: Lone Ranger

Lone Ranger Logo

This website contains information, images, an interactive animation, and a report from one laboratory group registered for ENSC494: Special Topics -- Micromachining and Microfabrication, Summer 2001. Since there is only one member in this group, the team name is, in reflection of this fact, "The Lone Ranger". The Lone Ranger submitted 44 designs of simple micromachine motors for fabrication in August 2001, and expects the fabricated desings back for testing in November 2001. Moderate estimates place design yield at 10%, which means I expect at least 4 motors to work. Look at their website.

ENSC494-01: SAM

Technically speaking, a BiStable Switch is a mechanical device which offers two stable end positions with a single actuation. However, complex mechanical devices usually defy explanation so an example of a BiStable Switch can be found on standard mechanical pen. Our goal in the ENSC 494 Micro-machining course was to design a BiStable Switch that could be fabricated as a micro-machined device. Look at their website.

ENSC494-01: Team Slayer

Team Slayer Logo

During the summer of 2001 we designed a bistable switch for implementation using MUMPs surface micromachining technology. In this site, you'll find: An explanation of our project, Screen captures from our design, Links related to ENSC 494 and micromachining, and Biographies of Team Members. Look at their website.

ENSC494-01: Vertically Challenged

Vertically Challenged has been assigned the task to build a linear actuator. In the micromachining world, linear actuators are used to direct tiny silicon mirrors. The specific difficulty in building linear actuators is the fact that all the components are fabricated lying horizontally, and the mirror is not easily tilted up. Vertically Challenged has implemented several ways to solve this problem, and awaits the results of fabrication in September. Look at their website.

Automated Design for Mumps

ADM Logo

Building complex systems is difficult enough without designers having to redesign the wheel over and over again. The bulk of the ADM is a library of customizable MUMPS parts. It also contains several Cadence technology files to help Cadence handle MUMPS designs more intelligently. The ADM has its own website.

Rotating Mirror for Optical Communications

Modern telecommunications rely heavily on optical fibers. That also means that telecommunications rely heavily on all of the components used to modulate and switch optical signals. This project is a design for rotating mirror that could be used for optical multiplexing/demultiplexing. This site has its own website

Gear Train Designs

Device SEM

The main goal of this project is to demonstrate one of the micro machining designs known as the gear train. The gear train design consists of series of interlocking gears with differeing sizes. Gear trains are used in a number of applications. The project has its own website.

Pseudo DAC

This DAC was developed to be used in conjunction with a mirror mounted onto a gear to serve as a proof-of-concept optical switch. The details of the components used in the DAC, the complete optical switch and other MEMS related information is available from this website.
