A very simple and low-cost optical sensor for measuring vibrations of mechanically supported thin films and other small objects will be developed. Such measurements are useful in characterizing elastic materials properties. The sensor is based upon the so-called self-mixing effect in lasers, which enables the assembly of velocimeters containing nothing more than a diode laser, a lens, and a sign ...

This project will demonstrate the technical merit and feasibility of Transition AbleAideTM, a needs-based system for assisting special educators and related service providers in matching students with disabilities with appropriate disability accommodations (including assistive technology, home automation devices, and other simple accommodations) to aid the transition from school to adult life, but ...

The adverse acoustical environments typically found in classrooms have led to the development and proliferation of a new generation of small sound systems usually referred to as "sound field systems" (SFS). Recent studies support the usefulness of SFS to enhance the intelligibility of teachers' voices for the benefit of students with mild unaided hearing losses or attention deficits, and normally ...

We will develop and test an innovative computer Assisted reading device for improving the ability ovisually impaired users to complete independent living tasks. The unique optical character recognitidevice requires only one hand for operation and can read food and pharmacological packaging includinThe user will acquire functional capability after only a few minutes of training. Since the incidencl ...

Enterotoxigenic E. coli (ETEC) is among the most important agents involved in pediatric diarrhea anmost frequently encountered cause of illness in visitors to these regions. It is estimated that 16 mindustrialized nations travel to ETEC-endemic regions annually, and that 30-70% of these travelers cdiarrhea. The overall objective of this work is to facilitate development of passive antibody producd ...
