AccuSense Product
Overview
Software

AccuSense® gives First Responders the power of a laboratory-grade, gaseous chemical detection system in a field-portable unit. It’s like having the entire GC lab and technicians with you in a simple to use one button system. It is the perfect portable device for the detection, identification, and quantification of Toxic Industrial Chemicals (TICs).

AccuSense uses Dual-Hyphenated Gas Chromatography (DHGC) technology for the separation of chemicals and a proprietary thermal detection system to display concentration levels of multiple chemicals simultaneously. The chemicals and concentration levels are displayed via wireless links to a laptop computer. Identified chemicals and concentrations are automatically displayed relative to published IDLH (Immediately Dangerous to Life and Health) values and displayed on the screen for decision analysis.

Typical GC-based solutions require the use of an inert elute gas, such as argon or nitrogen. Products which rely on these “consumables” cannot be deployed for continuous field operations or hazardous areas where humans should not be exposed.

AccuSense solves the “consumables” problem by using internally conditioned ambient air as its elute gas source. This results in uncompromised continuous operation capabilities and lack of human intervention during unit deployment.

Each AccuSense chemical signature is a three dimensional “fingerprint” that is highly distinguishable from all other chemicals and from “confuser” chemicals which create “false positives/negatives.” The patented detection and identification systems of AccuSense are a technology breakthrough for the industry, giving superior accuracy compared to competitive products and solutions.

AccuSense Neural Network

In the chemical detection business, it is critical to detect, identify, and in the case of AccuSense, provide the concentration levels of the chemicals present. All of this information needs to be provided without the appearance of false positives or false negatives. A false positive is a case in which a device indicates that a chemical is present when in fact it is not, while a false negative is a case in which a devices indicates that no chemicals are present when in fact they are. Unnecessary response to chemical detectors that are reporting false positives is costly and time-consuming, adding to the overall cost of the instruments. The cost of a false-positive reading in an area such as an airport or convention center can be extremely costly due to the unnecessary evacuation of the public and deployment of a HAZMAT team. Continual response to false-positives is unacceptable and the ability of AccuSense to distinguish between chemicals of interest and confusers will significantly limit the cost of unnecessary response actions.

SEER has created a unique state-of-the-art chemical separation and classification algorithm based partly on an artificial neural network algorithm. Because the neural network is trained only on known valid chemical signatures validated against an Agilent™ mass spectrometer, it is inherently robust with respect to false positives.

Part of the performance validation software runs all possible chemical combinations on the Cray™ supercomputer and produces a performance map which indicates exactly how the unit will respond.

The SEER "Picasso" is actually a 3D surface plot produced with Matlab™ scientific software on the Cray™ supercomputer. It is used as a quick visual check of the performance of a trained neural network chemical separation algorithm.

Also, a user does not need to worry about whether false positives will occur with any particular set of chemicals. Part of the performance validation software runs all possible chemical combinations on our supercomputer and produces a performance map which indicates the exact performance of the algorithm.

 

SEERID is an intuitive, easy to use software platform that provides chemical concentration results for multiple units back to one command post outside of the release area.

The color-coded data sets that automatically refresh every three minutes alert the user when concentrations approaching or exceeding IDLH values exist. The operator can then link to the National Institute of Occupational Safety and Health (NIOSH) Pocket Guide to Chemical Hazards to procure additional information about specific chemicals such as exposure limits, chemical properties, and personal protection techniques.

 

Applications

Industrial

Industrial Applications for AccuSense

Industrial chemical manufacturing sites offer a diverse range of deployment scenarios for AccuSense due to the number of chemicals that are manufactured, handled, and transported on a daily basis. The flexibility of AccuSense to be deployed in a fixed-position format or as a field-portable instrument enhances its capabilities in scenarios of all kinds.

Transportation

Transportation Applications for AccuSense

Mass transit systems like subways, train stations, and airports can be monitored with the AccuSense system. The constant foot traffic and constant influx of people creates a situation that needs to be constantly and closely monitored.

HAZMAT
HAZMAT Applications for AccuSense
HAZMAT Applications for AccuSense

HAZMAT teams require the flexibility to respond to a multitude of known and unknown situations involving exposure to dangerous gaseous chemicals. These teams need to quickly assess the magnitude of harm that the event could potentially yield and utilize each and every piece of detection equipment at their disposal. HAZMAT teams need to be empowered with the proper knowledge to formulate and implement a proper strategy for containment and resolution, which AccuSense will help provide.

Law Enforcement personnel are often the first to arrive on scene. As true First Responders, they are confronted with unique requirements that AccuSense can address.

For the Officer in the field responding to an incident, AccuSense provides the ability to quickly and accurately assess a situation for potential chemical danger, therefore bolstering protection protocols and enhanced personnel safety.

The Drug Court Probation Officer can employ AccuSense to efficiently develop and maintain a profile on the use of drugs and alcohol in probationer domiciles.

Perimeter Protection
Perimeter Protection
Perimeter Protection

Monitoring the perimeter of a location is a largely ignored but very important aspect of protection.  Whether it is a command post, manufacturing facility, or chemical storage location, monitoring the perimeter is an important aspect of security and safety.  AccuSense has the unique ability to continuously monitor the perimeter of a facility and provide relevant information to user.

Sporting Events
Stadium Protection
Stadium Protection

The numbers of people that attend sporting events make them attractive targets for terrorist and other intent on causing harm and gaining publicity.  Deploying AccuSense at these events will provide an effective way to provide information to first responders and security forces should the unthinkable happen.  It can also act as an effective deterrent to someone contemplating attacking these events if they know that an effective detection and response is available.
