This project will extend the microchannel resonator to the level of a few attograms, which will allow measurement of individual particles as small as 10 nanometers with unprecedented resolution. The Phase I effort will prove the feasibility of this approach by miniaturizing the MEMS sensors, thereby improving their intrinsic mass sensitivity up to 100-fold; and by simultaneously measuring the sens ...

THE "CROWN DICE" CERAMIC ITEMS WILL BECOME AVAILABLE BY POURING CLAY INTO MOLDINGS , THAN BURNING THEM AT THE KILNS AND PAINTING THEM TO BE READY TO GO FOR THE SHELVES . THE DESIGN IS : BELOW BOX --DICE; ON TOP OF THE BOX ARE JOKER STICKS.

Technology research and development in such areas as next-generation atomic clocks, quantum information processing with trapped ions, and atomic spectroscopy is impeded by the lack of commercially available laser sources that meet the required specifications of wavelength tuning range, output power, frequency-stability and reliability. Arete Associates is developing frequency-stable Optically Pump ...

The purpose of this project is to implement the process for a new method for the measurement of LED performance, but in a form that is low-cost, integrated, and easy-to-use, so that the barrier to entry is as low as is possible.

This proposal explores the feasibility of a communication system based on the modulation of a magnetic field. The principle of mutual induction states that the voltage induced by mutual induction in one inductor is always proportional to the rate of current change in the other inductor. If one inductor is in the transmitter, and the other inductor is in the receiver, the induced voltage in the r ...

Out of air situations present a hazard. They can result in a dangerous emergency ascent, or failure of a diver to reach the surface. A low air pressure alert (APA) device can provide a valuable margin of safety, but careful design is required. The device must be effective. In order for the device to be adopted and success, its ease of use, ergonomics and cost must be attractive in relationship ...

The characterization of biologically relevant polymetric materials is a major focus of the bioinstrumentation industry. Of particular interest is the rapid, direct sequencing of DNA through a nanopore as well as the characterization of other biopolymers. Although progress has been made with nanopore sequencing, some fundamental instrumental and system issues have so far kept the method from realiz ...

In recent years, there has been increasing concern about the role of man-made sound on the marine environment. For this effort, we propose developing an intuitive software interface for sound propagation modeling. This will be based on software developed at HLS Research, Inc. for similar applications. The software will use existing propagation modeling codes that have a long history in the unde ...

In this SBIR program, Structured Materials Industries, Inc. www.structuredmaterials.com (SMI) will develop tunable RF capacitors with ultra-low series resistance. The tunable capacitors will be based on the tunable dielectric material barium strontium titanate - BaxSr1-xTiO3 (commonly referred to as BST). Presently, two factors limit implementation of tunable BST capacitors in RF systems; 1) po ...

High resolution magnetic mapping is a technique that has shown great value in the forensic evaluation of magnetic audio recording tapes. The use of single element raster scan systems has shown that the technique has promise in diagnosing many other systems where internal currents or magnetized inclusions generate external measurable fields. NIST has developed a 256 channel MR array sensor that ha ...
