Modern lithium ion batteries are known for their poor safety performance, with many reports of battery failure and fire having been reported. One of the major causes of battery fire is from the use of flammable solvents, such as organic carbonates, as the electrolyte. These hazards have long limited the usage of batteries in dangerous conditions, such as on the battlefield. To combat this issue, t ...

Navigation of aircraft using the crustal magnetic field variation of the earth is a novel and developing technique for use in GPS-denied environments. Location estimation is accomplished by matching the magnetic field measurements in flight to a specific track on a magnetic map of the globe. Atomic scalar magnetometers are ideally suited for use on aircraft because they are not sensitive to aircra ...

We propose a two year program to develop an atomic vector magnetometer to replace standard commercial fluxgate magnetometers in use by the US Navy. Thousands of fluxgate magnetometers are used to measure ship magnetic signatures and they are often limited by low frequency drift. An vector magnetometer based on atomic spin will have significantly improved drift. The alkali metal atomic vector magne ...

Growing amounts of text and visual files are being stored in document archives at organizations' servers, network attached storage devices and cloud storage services. These archives contain valuable information that is not cataloged in a data-driven manner conducive to discovery.  Under an SBIR Phase II effort, Semandex developed Discovery, a cloud-based application that uses Natural Language Pro ...

Under SciTec’s Atmospheric InfraRed Transmittance Calculator (AIRTraC) Small Business Innovative Research (SBIR) effort, we developed a software application to perform autonomous ingest and fusion of available atmospheric profile data with that collected by a ground-based meteorological station to improve the atmospheric correction process for remotely sensed data. SciTec extends this previous w ...

Stealth communications is difficult. RF, including spread spectrum, illuminates, and thus can be used to locate transmitters. Further, RF is blocked by buildings, heavy foliage, water and it can be jammed and/or spoofed. This Static Magnetic Communications (SMC) concept uses vector magnetometer technology to read the change in field strength of a spinning permanent magnet modulated by a mu-metal c ...
