We propose to develop a MEMS-based optical shutter system with transition times faster than 10 microseconds and attenuations of at least 70 dB.The device will be designed for wavelengths between 780 and 894 nm, as needed for laser systems for cold-atom microsystems.Specific design features and techniques will be incorporated to trap and prevent the passage of stray light through the system.

AlphaTRAC proposes to continue the research and development effort of the AlphaACT? SBIR Phase I Project. We will develop human dynamics (non-verbal) cues and social interaction-based courses of action and incorporate them into a customized version of the AlphaACT decision training platform. The new technology will be called AlphaACT SI.

ColdQuanta proposes to develop a MOT-based laser-cooled microwave atom clock prototype having a stability of at least 1E-12 for a 1 s integration time that can serve as a primary atomic frequency. Phase I focuses on the key challenges facing the development of a cold atom physics package commensurate with 1 liter total system size. We will design, build, and demonstrate an ultrahigh vacuum cell ...

We present a technical approach for the design of a small, portable, microwave cold atomic clock that meets the frequency stability requirement of less than 1X10-12 at 1 s averaging time and less than 5X10-15 for an averaging time of 1 day in the following size weight and power requirements (SWaP). Our approach is based on a laser-cooled atom microwave fountain clock that uses precision microwave ...

In the area of supply chain integrity improvement, the US defense and intelligence sectors anticipate multiple uses for the forensic capability to characterize an electronic component for the purpose of identifying the semiconductor fabrication facility w

This program will develop an automated, computer-assisted method for tracking a semiconductor device back to the fab that produced it. To accomplish this goal, we will measure characteristics of the device that are consistent within a given fab toolset, and compare the results to known authentic parts in order to establish a match. This technique will for the first time enable a simple inspectio ...

Genome-scale predictable cellular design and engineering of biomanufacturing systems is the overarching goal of DARPAs Living Foundries and 1000 Molecules programs and, if realized, will enable rapid engineering of living systems for a broad range of applications in biotechnology and pharmacology. However, constructing living cells with designed genome is an arduous task that is severely limited ...

The proposed Pioneer Sea Glider is a new method for underwater transport of equipment and personnel over long distances in a quiet manner. A unique buoyancy control system is based on the conversion of liquid nitrous oxide to a mixture of gaseous nitrogen and oxygen. This nitrous-oxide-derived buoyancy gas can also provide breathing air and heat for crews and is based on technology developed and p ...

The DARPA Phraselator is a, multilingual phrase translation system. The Phraselator is a rugged, weather resistant, voice-to-voice, translation device with superior audio input and output. It is available to both military and industrial users and more than 2,000 Phraselators have been manufactured and delivered. Because of the significant capabilities of this custom device, the cost is relative ...

We propose to develop and demonstrate thin-film transistors (TFTs) capable of operation at microwave and millimeter-wave frequencies. These ultra-fast devices are based on a patented metal-insulator tunneling hot electron transistor structure. Comprising thin films of only metals and dielectrics, our TFTs require only low temperature processing and should be inherently compatible with large-area ...
