Snug Fit Crescent Wrench, Jacob M. Miterko, Michael E. Buchbinder, Gavin J. Griffith, Andrew J. Jarrett

Williams Honors College, Honors Research Projects

The most commonly used brand of adjustable wrench, a Crescent Wrench, dates back to the early nineteen hundreds. The tolerances associated with the adjustable wheel used by the most common adjustable wrench designs allow the position of the lower jaw to vary while using the tool. These undesired fluctuations in the position of the lower jaw make it difficult to adjust the wrench to the desired position and keep it in position once the desired position is set.

The proposed adjustable wrench design addresses the tolerance issues by constraining the lower jaw with a new mechanism. The mechanism makes minor …

Miniature Photogrammetry Rig, Alec Geither, Sean Weber

Williams Honors College, Honors Research Projects

Photogrammetry is a process that accurately gathers measurements from multiple photographs, capturing all sides and angles of the object. As long as a point is visible in at least three different photographs, its position can be triangulated accurately relative to each other point on the model. This process has a diverse range of applications, from surveying land to developing virtual training systems for professional athletes. One interesting application for photogrammetry is to create highly accurate electronic three-dimensional models from a series of photographs. We intend to build a miniature photogrammetry rig for use at the University of Akron.
