Cable-line Safety System: Electro/hydraulic Emergency Stop Device for a Winch, Drum or Capstan

This CDC-developed invention entails a system of electrical and hydraulic circuits used to stop a rotating winch in an emergency. Amongst other locations, one stop switch can be positioned on a capstan winch horn. This location makes it available to a victim entangled in rope being retrieved on a gypsy drum. As designed, the stop circuit could be used with an electrically, hydraulically or pneumatically operated winch. A variant of this safety system has been successfully tested on a purse seining fishing vessel in Alaskan waters.

Mining Safety: Personal Dust Monitor Filters for Accurate, Quantifiable Spectrometric Analysis and Assessment of Worker Exposure Levels

This CDC-developed invention pertains to a novel dust monitor filter that is specially constructed of organic materials for spectrometric analysis, ultimately allowing for detection and accurate quantification of a particular chosen analyte (e.g., crystalline silica/quartz dust that may lead to silicosis).

Computer Controlled Aerosol Generator with Multi-Walled Carbon Nanotube Inhalation Testing Capabilities

This invention pertains to a CDC developed sonic aerosol generator that provides a controllable, stable concentration of particulate aerosol over a long period of time for aerosol exposure studies. Specifically, in situ testing data indicate uniform aerosol stability can be maintainable for greater than 30 hours at concentrations of 15 mg/m3 or more. Additionally, the technology was specifically developed for, and validated in, animal studies assessing exposure to airborne multi-walled carbon nanotubes (MWCNT).

Human Influenza Virus Real-time RT-PCR: Detection and Discrimination of Influenza A (H3N2) Variant from Seasonal Influenza A (H3N2) Viruses, Including H3v and Seasonal H3 Assays

This invention relates to methods of rapidly detecting influenza, including differentiating between type and subtype. CDC researchers have developed a rapid, accurate, real-time RT-PCR assay that has several advantages over culture and serological tests, which require 5 to 14 days for completion; this assay can also be easily implemented in kit form. To date, hundreds of human cases of infection with the H3N2 variant virus have been confirmed.

Silica Exposure Safety: Mini-baghouse Systems and Methods for Controlling Particulate Release from Large Sand Transfer Equipment

CDC/NIOSH scientists have developed an effective point-source control for silica-containing dusts that can be generated from machinery on sites where hydraulic fracturing is occurring. The CDC/NIOSH mini-baghouse retrofit assembly is a bolt-on control designed to contain silica-containing respirable dusts generated during refill operations of sand movers during hydraulic fracturing.

Human iPSC-Derived Mesodermal Precursor Cells and Differentiated Cells

Cells, cell culture methods, and cell culture media compositions useful for producing and maintaining iPSC-derived cell lines that are of higher purity and maintain cell type integrity better than current iPSC-derived cell lines are disclosed. Human induced pluripotent stem cells (hiPSCs) can be generated by reprogramming somatic cells by the expression of four transcription factors. The hiPSCs exhibit similar properties to human embryonic stem cells, including the ability to self-renew and differentiate into all three embryonic germ layers: ectoderm, endoderm, or mesoderm.

Compositions and Methods for Improved Lyme Disease Diagnosis

This CDC-developed technology entails novel compositions and methods related to the diagnosis of Lyme disease. Lyme disease, caused by the Borrelia burgdorferi bacterium, is the most common tick-borne infectious disease in the US and Europe. Diagnosis of Lyme disease is particularly challenging as symptoms often appear long after exposure. At present, the only FDA-approved diagnostic for Lyme disease involves patient blood tests for particular antibodies; these include an ELISA to measure patient antibody levels and a Western blot assay to detect antibodies specific to B.

Exposure and Activity Detection Assays for Anthrax Lethal Factor and Lethal Toxin

This CDC developed invention identifies an assay for extremely fast and sensitive detection of Bacillus anthracis lethal toxin (LTx), the toxin responsible for the lethal effects of anthrax infection. This assay has already been successfully tested in animals and will allow for early detection of anthrax exposure and screening of lethal factors to monitor anthrax toxicity, for example for vaccine trial candidates.

Local Positioning System for Position-Time-Condition Correlation, Data-logging and Analysis

This CDC-developed technology describes an automated system for monitoring worker hazard exposures by recording data about where and when hazards occur in a workplace or other environment. This allows the hazards to be avoided and harmful exposures and risks reduced. This field-tested technology consists of an integrated, hand-held electronics instrument and software system that will precisely correlate multiple exposure levels with position coordinates of the user and features real-time data acquisition.

Simple, Field-Usable Fluorescence-Based Isothermal LAMP Assay for the On-Site Diagnosis of Malaria

CDC researchers have developed improved Loop-Mediated Isothermal Amplification (LAMP) assays for the nucleic acid-based diagnosis of malaria in field settings. The approach employs Plasmodium genus-specific LAMP primers and a portable tube scanner to run the LAMP reaction and measure fluorescence signal (e.g., SYBR green) as a measure of DNA amplification in real time. Using this platform, the researchers were able to detect several different species of the human malaria parasites.
