NASA's Hot 100 Technologies: Power Generation & Storage

Model-Based Prognostics For Batteries Effective Battery Health Monitoring (BHM) technologies are needed to ensure that battery operation is optimal and, if not, that it stays within design limits. BHM technologies protect the asset’s batteries from degradation due to non-optimal usage, and ensure viable levels of system availability, reliability, and sustainability in the presence of degraded batteries.

NASA's Hot 100 Technologies: Propulsion

Fully Premixed, Low-Emission, High-Pressure, Multi-Fuel Burner This burner is capable of operating on a variety of gaseous fuels and oxidizers, including hydrogen-air mixtures, with a low pressure drop. The burner provides a rapidly and uniformly mixed fuel-oxidizer mixture that is suitable for use in a fully premixed combustion regime that has the benefits of low pollutant emissions and freedom from harmful flashback effects, combustion instabilities, and thermal meltdown problems.

NASA's Hot 100 Technologies: Robotics, Automation & Control

Inductive Monitoring System IMS software utilizes techniques from model-based reasoning, machine learning, and data mining to build system-monitoring knowledge bases from archived or simulated sensor data. In real time, IMS performs monitoring functions, determining and displaying the degree of deviation from nominal performance. IMS trend analyses can detect conditions that may indicate a failure or required system maintenance.

NASA's Hot 100 Technologies: Sensors

Gas Sensors Based on Coated and Doped Carbon Nanotubes Electronic, inexpensive, low-power gas sensors are based on single-walled carbon nanotubes (SWCNT) and provide a method for gas detection by coating or doping the SWCNTs with suitable materials. Applications include detection of flammable gases for the petrochemical industry, methane detection for the mine safety industry, environmental monitoring of toxic industrial gases, and monitoring gases in a patient’s breath.

Industry Roundtable: Imaging Technology

Few technologies have impacted the scientific community – and non-scientific community for that matter – as much as digital imaging technology. From exotic, high-speed imaging systems to rugged machine vision systems to a vast array of sophisticated consumer devices, digital cameras are everywhere these days, documenting every aspect of this world we live and work in. Photonics Tech Briefs recently spoke with executives from four well-known imaging companies to get their perspectives on where imaging technology is today, and where it is going in the future.

Evaluating Electrically Insulating Epoxies

Epoxies are versatile polymer systems that are “go-to materials” for electrical, electronic, and microelectronic systems, especially in applications where outstanding electrical insulation properties are needed. Their wide usage is due to their excellent adhesion to a wide variety of substrates, superb chemical and heat resistance, and long-term durability. They are serviceable for bonding, sealing, coating, and encapsulating/potting applications.
