Improving the quality and intensity of the x-ray beam is an important design goal for every synchrotron installation. Although small, the effects of vacuum windows on x-ray absorption and phase contrast cannot be neglected. Synchrotron x-rays have wavelengths on the order of one Angstrom (1 x 10-10m), the same order of magnitude as inter-atomic distances. These x-rays are used to study many differ ...

The ability to electronically identify users and their devices is increasingly becoming an integral part of our interaction with computing platforms. Whether an operating system is contacting the manufacturer's web site to confirm its proper registration and payment today, or a cell phone is broadcasting entrance credentials to a secure physical site tomorrow, it is apparent that identifying infor ...

CAD CAM technologies have had an immense impact on the product development process in the last two decades. Current technologies, however, have limited knowledge representation and computational capabilities to enable collaboration of design decisions beyond commercial Internet based collaboration tools. In the Phase 1 Lateral Eye proposes to develop a new framework for Knowledge Integrated comput ...

This proposal is aimed at developing a full software solution for the next generation advanced optical metrology. Existing simulation tools cannot meet the current and future needs of scattering-based optical metrology for semiconductor manufacturing. Our proposed work will first focus on developing an enhanced RCWA-based simulation engine with advanced algorithms for fast convergence and stabilit ...

New innovative technology for the visually impaired has been developed by NIST. If commercialized, it would provide refreshable tactile graphical information to the visually impaired, enabling them to compete on a more equal footing in the workplace and the education system.

The most practical arrangement for investigating moving fires within a restricted space is to use a high- resolution stand off technique. One such method that fits this description is the use of a staring infrared (IR) sensing device (i.e. imager).

A GHz-rate phase-stabilized fiber-laser frequency comb system is proposed to be used as a light source for coherent Fourier transform spectroscopy. The system will be developed based on our proprietary glass/fiber technology, which features a low-cost, robust, highly stable, mid-infrared light source that enables the development of a robust portable c-FTIR spectrometer for absorption measurements ...

In the proposed Phase I SBIR program, Aymont Technology and CoolCAD Electronics will design and demonstrate prototype silicon carbide (SiC) avalanche photodiodes (APD) specifically designed for high-efficiency, single-photon counting of 121.6 nm Lyman-alpha photons. This detector will be provided to relevant personnel at NIST for calibration and testing. Both discrete APDs and arrays will be used ...

This is an SBIR Phase II proposal to develop a tactile refreshable computer display prototype (TRCD) that will support multiple tactile alphabets (e.g. ELIA, braille, and Roman), multiple lines of text, and graphics to benefit the more than 1.8 million blind Americans. Commercially available TRCDs are expensive (~$12,000, or $19 per actuator), provide only one line of text (with 640 actuators) and ...

A wireless sensor and actuator network capable of providing precision time synchronization between the nodes of the network will be developed. The IEEE 1451.0 smart transducer interface and IEEE 1588 time synchronization standards will be combined, with additional software and hardware to provide synchronization between the clocks on the Wireless Transducer Interface Modules (WTIM) sensors/actuato ...
