Small CO2 Sensors Operate at Lower Temperature

Lower operating temperature translates to lower power demand. Solid-electrolyte-based amperometric sensors for measuring concentrations of CO2 in air are being developed for use in detection of fires, environmental monitoring, and other applications where liquid-based electrochemical cells are problematic. These sensors are small (sizes of the order of a millimeter), are robust, are amenable to batch fabrication at relatively low cost, and exhibit short response times (seconds) and wide detection ranges.

Tele-Supervised Adaptive Ocean Sensor Fleet

The Tele-supervised Adaptive Ocean Sensor Fleet (TAOSF) is a multi-robot science exploration architecture and system that uses a group of robotic boats to enable in-situ study of ocean surface and subsurface characteristics. TAOSF can study dynamics of ocean phenomena such as coastal pollutants, oil spills, hurricanes, or harmful algal blooms.

Utilizing Ocean Thermal Energy in a Submarine Robot

A proposed system would exploit the ocean thermal gradient for recharging the batteries in a battery-powered unmanned underwater vehicle (UUV) of a type that has been deployed in large numbers to research global warming. A UUV of this type travels between the ocean surface and depths, measuring temperature and salinity.

Alternative OTEC Scheme for a Submarine Robot

An alternative system for exploiting the ocean thermal gradient to generate power would be based on the thawing-expansion/freezing-contraction behavior of a wax, or perhaps another suitable phase-change material. The power generated by this system would be used to recharge the batteries in a battery-powered unmanned underwater vehicle.

Fuel-Cell Power Systems Incorporating Mg-Based H2 Generators

Two hydrogen generators based on reactions involving magnesium and steam have been proposed at NASA’s Jet Propulsion Laboratory as means for generating fuel (hydrogen gas) for motor vehicles. The generators would make it unnecessary to rely on expensive, heavy, bulky, or unsafe hydrogen storage systems previously developed.

Deciphering the New SUMIT™ Specification

The new SUMIT specification is managed by the Small Form Factor Special Interest Group (SFF-SIG). SFF-SIG is a newly formed, non-profit industry group that develops, promotes, and supports small form factor circuit board specifications and related technologies. The group embraces the latest technologies, but also has a philosophy of maintaining legacy compatibility and enabling smooth transitions to next-generation interfaces.
