Controlling Devices Using the Ear as an Output Source
Read More >>
This method creates a hands-free way of controlling devices such as medical equipment, wheelchairs, computers, and cell phones.
Current methods of device control include joysticks, which involve using one or both hands, external microphones that are cumbersome and pick up ambient noise, and external arrays that are also ...Read More >>
Wireless Patient Monitoring Based on Personal Area Networks
Read More >>
This system can integrate with devices such as blood pressure meters and electrocardiograms.
The Wireless Patient Monitoring System deploys the Zigbee standard to create a Personal Area Network (a wireless network with a coverage area of around 10 m) that is capable of integrating into the same wireless network ...Read More >>
Particle Distribution on Webs or Cloths
Read More >>
This technology provides the ability to uniformly distribute and attach particulate matter onto fibrous composite sheet or web materials.
This technology provides a methodology and products that are formed from fibrous substrates or film-like surfaces by uniform impregnation with a particulate that is subsequently firmly attached. The extremely ...Read More >>
Apparatus for Cold, Pressurized Biogeochemical Experiments
Bacteria are grown under conditions imitating those at ocean depths.
A laboratory apparatus has been devised as a means of studying plausible biogeochemical reactions under high-pressure, low-temperature aqueous, anaerobic conditions like those conjectured to prevail in a liquid water ocean on Europa (the fourth largest moon of ...

Hollow Radiopaque Bioactive Microspheres Carry Drugs in Embolization Procedures
Read More >>
Combining embolization therapy with localized drug delivery, application of biomaterials is more effective.
The number of applications of synthetic biomaterials continues to expand. However, the imaging of injected biomaterials is important to control the treatment procedure in real time, to avoid complications, and to assess therapeutic success. Embolization ...Read More >>
Isolation of Resistance-Bearing Microorganisms
Strategies were explored for inactivating resistance-bearing microorganisms, focusing on a new species (Bacillus horneckii sp. nov.) discovered on the surfaces of the Kennedy Space Center cleanroom facility in which the Phoenix lander was assembled. Two strains that belong to this novel species were isolated and subjected to a comprehensive, polyphasic ...

Growing B Lymphocytes in a Three-Dimensional Culture System
Read More >>
Cells grown in this system live long and closely resemble in vivo cells.
A three-dimensional (3D) culture system for growing long-lived B lymphocytes has been invented. The capabilities afforded by the system can be expected to expand the range of options for immunological research and related activities, including ...Read More >>
Liquid Cooling/Warming Garment
Read More >>
This lightweight garment can be used by firefighters, soldiers, and personnel working with hazardous materials.
The NASA liquid cooling/ventilating garment (LCVG) currently in use was developed over 40 years ago. With the commencement of a greater number of extra-vehicular activity (EVA) procedures with the construction of the International ...Read More >>
Tissuelike 3D Assemblies of Human Broncho-Epithelial Cells
Read More >>
Experimental conditions are more realistic than those of 2D monolayer cell cultures.
Three-dimensional (3D) tissuelike assemblies (TLAs) of human bronchoepithelial (HBE) cells have been developed for use in in vitro research on infection of humans by respiratory viruses. The 2D monolayer HBE cell cultures heretofore used in such ...Read More >>
Oscillating Cell Culture Bioreactor
Read More >>
This bioreactor is well suited to work with different biological specimens.
To better exploit the principles of gas transport and mass transport during the processes of cell seeding of 3D scaffolds and in vitro culture of 3D tissue engineered constructs, the oscillatory cell culture bioreactor provides a flow ...Read More >>
Dual Optics/Ultrasound Imaging and Contrast Media for the Detection and Characterization of Prostate Cancer
Read More >>
Acousto-optic imaging could be used to detect prostate cancer in vivo.
Detection of prostate cancer has frequently been plagued with inadequate sensitivity and specificity. Hypoxia is the hallmark of malignancy because aggressive cancers outgrow their blood supply. Optical imaging is emerging as a physiologic tool capable of quantifying ...Read More >>
Photochemical Tissue Bonding for Military Medical Applications
Read More >>
A two-wavelength laser and albumen stent easily repair separated vessels.
Joining severed vessels is a recurring problem in trauma and surgery. The basic technology of joining vessels using sutures has been available for centuries, but remains a slow and tedious process. A complete system for micro-anastomosis of vessels ...Read More >>
Magnetic Nanoparticles and Devices for Biomedical Uses
Read More >>
Potential applications include detecting selected biomolecules and treating some brain injuries.
A program comprising several collaborative research efforts has been dedicated to advancing the art of utilization of magnetic nanoparticles for biomedical purposes. The research has been performed by three teams, each focusing on different aspects of the ...Read More >>
Endotracheal Intubation Device with Built-in Stylet and Colormetric Indicator
Read More >>
This device requires no assembly, saving time in life-threatening situations.
An endotracheal intubation device is utilized by doctors and paramedics to mechanically create an airway and to ventilate an injured person. The most common ventilating practice in the paramedic industry today requires assembly of a three-piece system at ...Read More >>
