Award Data

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...

The accurate identification of seafood species and origin has become an extremely important topic in the food industry. Mislabeling a lower valued seafood product to represent a species of higher value constitute economic fraud. In addition, this mislabeling compromises proper geographic origin labeling and fishery management efforts. DNA barcoding for seafood species identification provides re ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

During the Phase I SBIR Effort, Mainstream demonstrated a unique vehicle monitoring system (VMS) for tractor trailer applications. The development was driven by the need to easily store, retrieve, and transfer key trailer parameters to the tractor and the need to electronically transfer key driver, tractor, and trailer information to roadside inspectors and maintenance personnel. In Phase I, we ...

Autonomous inspection systems are necessary to increase awareness of track safety and maintenance issues. However, electrical power for these systems is not available under freight railway vehicles. Mainstream Engineering (MEC) proposes development of a small-scale diesel generator with an integrated starter-alternator (ISA) and automated battery charging circuit for this application. The proposed ...
