Tech Needs of the Week

A company is looking for effective personal skincare products for niche applications where the efficacy can be clearly demonstrated. The products, product ranges, and/or brands should offer relief for common skin conditions. Products will preferably be topically applied. They should also be on the market and recognizable by the consumer. Orally ingested, prescription, and purely cosmetic items are not of interest. Click here for more info.

Two Mathematical Models of Nonlinear Vibrations

Model parameters are fit to empirical vibration data. Two innovative mathematical models of nonlinear vibrations, and methods of applying them, have been conceived as byproducts of an effort to develop a Kalman filter for highly precise estimation of bending motions of a large truss structure deployed in outer space from a space-shuttle payload bay. These models are also applicable to modeling and analysis of vibrations in other engineering disciplines, on Earth as well as in outer space.

Large Solar-Rejection Filter

This lightweight filter comprises a multilayer spectral coating on a flexible membrane. An optical filter consisting of a multilayer spectral coating on a flexible membrane has been designed to be placed in front of the 200-in. (5.08-m) Hale telescope on Mt. Palomar. The filter is intended to protect the telescope against solar radiant flux and limit solar heating of the interior of the telescope dome while transmitting light at the 1,064-nm wavelength of the Mars Laser Communication Demonstration.
