    Integral habitat transport system (1994)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: In the 1993 Fall quarter, the ME 4182 design class was sponsored to study various scenarios that needed to be studied for Martian travel. The class was sponsored by NASA and there were several different design projects. The design that group three chose was an integral transport system for a Martian habitat. An integral transport system means the design had to be one that was attached to the habitat. There were several criteria that the design had to meet. Group three performed an in depth study of the Martian environment and looked at several different design ideas. The concept group three developed involved the use of kinematic linkages and the use of Martian gravity to move the habitat. The various design concepts, the criteria matrices and all other aspects that helped group three develop their design can be found in their 1993 ME 4182 design report. Now it is Winter quarter 1994 and group three is faced with another problem. The problem is building a working prototype of their Fall design. The limitations this quarter were the parts. The group had to make the prototype work with existing manufactured parts or make the parts themselves in a machine shop. The prototype was scaled down roughly about twelve times smaller than the original design. The following report describes the actions taken by group three to build a working model.

    Collectors Of Airborne And Spaceborne Particles (1991)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Brushlike collectors capture samples of dust and other particles in space vacuum or air for optical, scanning-electron-microscope, and/or x-ray analysis. Gently decelerates particles without damaging them, minimizing tendency of some particles to rebound. Depending on design of specific collector of this type, it captures particles ranging upward in size from fractions of micrometer to few micrometers.

    Polarization-Rotating Sensors Connected To Optical Fibers (1992)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Proposed optoelectronic sensor system includes polarization-rotating sensing elements interrogated by polarized light transmitted to and from sensing elements along optical fibers. Polarization of light altered by combinations of inherent birefringence, stress-induced birefrigence, and Faraday rotation. Advantages include: light weight, fast response, immunity to electromagnetic interference at radio and lower frequencies, and no need to supply electrical power to sensing elements.
