Enhanced Auditory Alert Systems

Auditory warning systems for human interfaces are often designed around criteria that depend primarily upon signal loudness. It is well understood from the auditory literature that, by making an alert signal substantially louder than the measured background noise level, one can insure that an alert signal will be...

Slot-Sampled Optical PPM Demodulation

In order to demodulate an optical PPM signal, the receiver must align its slot clock to that of the received waveform to count the number of arrivals within each slot. The large bandwidth expansion factor of PPM, M/log2(M) requires a prohibitively large sample rate when a fixed sample clock N...

Extended-Wear Patches for Skin Hydration

Moisturizers and active ingredients must be held against human skin in a patch format. To enhance uptake, a new material needs to be designed for extended wear from 1-10 hours. Comfort and physical flexibility are two chief requirements. Ideally, the patch will also reduce the appearance of wrinkles....

Morphable Surfaces Reduce Air Resistance

A morphable surface developed by an MIT team can change surface texture — from smooth to dimpled, and back again — through changes in pressure. When the inside pressure is reduced, the flexible material shrinks, and the stiffer outer layer wrinkles. Increasing pressure returns the surface to a smooth...
