Proposal Information 0714011 - Handheld Trace Explosives Sampler
Topic Information H-SB07.1-001 - Trace Explosives Particle and Vapor Sample Collection
Award/Contract Number NBCHC080100

Non contact trace explosives detection has not been comparable to results obtained from wipe sampling. Many issues, including finding a method to release particles from a surface, efficient particle and vapor transport, and limited particle and vapor trap collection efficiency have all limited the process. Other related issues have included cost of ownership, ease of contamination removal, and compatibility with existing detection equipment. This Phase II proposal summarizes work performed on a Phase I SBIR program to develop solutions for these problems. The methods used in the final prototype hand sampler include aerosol ablation for particle release, a vortex attractor for particle and vapor transport, and a planar stainless steel mesh with optional coating for particle and vapor collection.

Suite 350
Matawan, NJ 07747-3911

Proposal Information 0712002 - Sensor Fusion Software to aid in response and evacuation of subterranean incidents
Topic Information H-SB07.1-002 - Subterranean Response and Evacuation
Award/Contract Number NBCHC080099

The speed at which an attack is detected is a critical trigger for all responses to follow. The accurate determination of the type of attack will determine the type of emergency personnel and response needed. The location will determine the target response area as well as determine by proximity which of the responders that are available can be first on the scene. Therefore, a system that can do that based on a multitude of input feeds such as sensors and other systems is of out most importance. While sensor put out information - making sense in quick fashion of the data is paramount. People tend to panic in situations of high stress whereas a system can help by a "one button" trigger point. A system that can fuse data from multiple sources, correlate it, find the root cause, and then automatically notify the required first responders as well as the victims will play a significant role in helping evacuate victims in a timely manner and therefore save lives.

Waltham, MA 02451-1016

Proposal Information 0714012 - Tamper-Resistant Stretch Wrap
Topic Information H-SB07.1-003 - Secure Wrap
Award/Contract Number D09PC75587 (formerly NBCHC090022)

The selected approach has been devised with the objective of fabricating an anti-tamper stretch wrap material that preserves the essential optical, mechanical, and thermal properties of existing wrap products, while providing a very effective and easily detectable method for tamper detection using low cost materials and processes.

Suite #190
Maple Grove, MN 55369-5457

Proposal Information 0712001 - Mobile Stand-off Secure Wireless Biometrics Screening Device
Topic Information H-SB07.1-004 - Mobile Biometrics Screening
Award/Contract Number D09PC75411 (formerly NBCHC090019)

Lightweight portable biometrics tools are needed to accurately and rapidly screen and manage the identities if individuals at the scene of an incident. Such tools are preferably not dependent on local infrastructure, which may be compromised, and should operate in both land and maritime environments. The output of this phase II project will be a prototype portable biometrics screening device.


Trident Research LLC
2809 Longhorn Blvd
Austin, TX 78758-7623

Proposal Information 0712005 - Global Biometrics Gateway System
Topic Information H-SB07.1-004 - Mobile Biometrics Screening
Award/Contract Number NBCHC090015

DHS field agents do not have a device that provides them the ability to rapidly screen and manage the identities of individuals they encounter during routine operations or following terrorist incidents and natural disaster, when no local communications infrastructure is available. A device to fill this need must be portable, operable in all weather conditions, provide the ability to capture biometric data in the field, and have the ability to send data over a secure link to a biometric database such as the DHS biometric database (IDENT) to query for biometric matches. The Phase I effort identified a viable technical architecture for a Biometrics Gateway System that links COTS handheld scanners with a remote biometric database without relying on local infrastructure. The Biometric Gateway supports a broad range of DHS and US Government agencies in an architecture that can be tailored to meet specific agency CONOPS and provides renewed life to legacy biometrics scanners presently in the field. The Phase II effort will culminate in operational field testing of two prototype biometrics communications managers with 802.11, Bluetooth, cellular, and satellite-based communications capability, and a prototype remote gateway portal to facility queries to CONUS-based databases, such as IDENT.



UtopiaCompression Corporation

Suite 820
Los Angeles, CA 90064-1839

Proposal Information 0712010 - Responder Wireless Physiological Monitoring Device
Topic Information H-SB07.1-005 - Responder Wireless Physiological Monitoring Device
Award/Contract Number NBCHC090020

Today`s state-of-the-art Medical-Vests-Shirts are inflexible and expensive. Typically, data collection component functions as a multi-channel cardiopulmonary digital-recorder with physiologic-sensors-array sewn to the shirt to monitor vital signs. The lack of flexibility-integral-unity and cost of the current vests is a prohibiting factor in their use in first responder applications. The vests also lack an in-built intelligence to accurately determine the health status of the person wearing the vest. UtopiaCompression Corporation UC is developing a hardware-software solution for remote based health monitoring with one specific application to monitoring the health status of first responders in pressurized and adversarial missions. The technology under development consists of two main components. The first component is a physiological vest consisting of a suite of physiological sensors interfaced with energy management units designed to prolong the life of the sensors. The sensor suite is designed to be easily integrable with currently available first responder vests. The sensors communicate wirelessly with a personal server consisting of a Decision Support Software DSS, which forms the second - truncated, over 200 words



AccessData Corporation
384 South 400 West
Suite 200
Lindon, UT 84042-1956

Proposal Information 0712003 - AccessData DNA-Grid Phase II Proposal
Topic Information H-SB07.1-006 - Enhanced Project Safe-Cracker
Award/Contract Number NBCHC080095

AccessData is proposing enhancements to its Distributed Network Attack (DNA) product to increase the functionality which will increase the number of workstations that can participate in the system; from approximately 1,000 to potentially 1,000,000 workstations. This will be accomplished by coupling its world class password attack technology with a proven open source desktop grid computing infrastructure (BOINC) that leverages the unused CPU cycles of existing end-user workstations deployed within an organization. The resulting product will be called DNA-Grid. DNA-Grid will be available as an upgrade to organizations already running DNA. A deployment of DNA-Grid which permits the submission of files via the Internet over an authenticated, secure (HTTPS), connection will allow small law enforcement agencies to gain access to the computing power of the system at a reasonable cost.



Next Dimension Technologies, Inc.
1 West Mountain Street #11
Pasadena, CA 91103-3070

Proposal Information 0712008 - Stabilized Chemisorptive Microsensor Arrays for Small Molecule Gas Detection
Topic Information H-SB07.1-007 - Improved Chemiresistor Sensing Arrays for Detection of Small Molecules Gases
Award/Contract Number NBCHC080092

The release of hazardous chemical vapors has the potential for severe casualties, and the detection of such chemicals is therefore critically important for homeland security. Despite this threat, there exists no commercially available, portable gas detection product that can quickly and cost-effectively sense most hazardous gases. In this Phase II project, we will develop a prototype gas detection system for reactive small molecule gases using a new generation of stable chemisorptive sensor materials that are highly sensitive towards reactive small molecule gases and that can withstand repeated exposures to multiple reactive analytes. The sensor arrays will be fabricated using techniques developed in Phase I that were shown to greatly enhance response stability, and the detection system will incorporate new drift-compensation algorithms. Performance characteristics of the prototype system will be validated with a broad range of hazardous chemical vapors of interest to DHS. In a continuing Phase III effort, we will optimize the prototype system for real-world environments and develop a production-ready system.



Advanced Fuel Research, Inc.
87 Church Street
East Hartford, CT 06108-3728

Proposal Information FY07.1-0711211-II - Radiological Source Surveillance With RedStar Video-Centric Radiation Detection
Topic Information H-SB07.1-008 - Source Surveillance
Award/Contract Number HSHQDC-08-C-00130

Radiological sources are in everyday use in numerous industries. Illicit removal of this material from storage could result in construction of a Radiological Dispersal Device or "Dirty Bomb." A pervasive means of securing radiological materials and identifying breaches in security is required. Ideally, existing passive surveillance technology would be used, thereby enabling rapid and cost effective deployment. Advanced Fuel Research (AFR) developed and is commercializing a software solution designed to reduce the likelihood of malicious use of radiological materials. Analytical software (U.S. Patent #7,391,028) evaluates images from security cameras to search for the characteristic small "spots" that appear in images when a radiological source is nearby. AFR's RadiationEvent Detection System: Tracking And Recognition (RedStar(TM)) software detects these image artifacts. The software¿s data capture and analysis routines feed an alert messaging engine. When the software detects radiological sources, it sends alert messages using a variety of open protocols. Under the Phase 1 project, RedStar data flexibility was upgraded and tested at Hartford Hospital. During the week-long test, it detected the radiation source each time it was used, detected the source while it was still in its shielded container, and produced zero false alarms.



HY-Tech Research Corp.
104 Centre Court
Radford, VA 24141-5123

Proposal Information FY07.1-0711040-II - Manufacturing of a low-cost, high efficiency, solid-state neutron detector
Topic Information H-SB07.1-009 - Improved Solid-State Neutron Detection Devices
Award/Contract Number HSHQDC-09-C-00005

The main objective of this DNDO SBIR-funded effort is to enable large-scale and economical production of high-sensitivity, solid-state, thermal neutron detectors for use in radiological inspection. The Phase I project successfully demonstrated a novel, energetic ion technique for depositing the active material, boron-10, onto the patterned silicon, which forms the substrate for the device. Micron-scale trenches of about 3:1 aspect ratio were completely filled with dense, pure boron, with minimal ridge coating and with no substrate damage. The project paralleled the continuing development of "Pillar Array", high efficiency neutron detectors at the Lawrence Livermore National Laboratory (LLNL). In the Phase II project this deposition processes will be validated and optimized for the devices based on the Pillar Array concept and the work will be in close collaboration with LLNL to help move the optimized device to the commercial stage. The work at HY-Tech will include infill of larger aspect ratio trenches and scale up to 4" wafer. Testing at LLNL will include stress analysis, as well as thermal neutron conversion efficiency measurements to qualify the deposited material. HY-Tech will also work with LLNL to develop partnerships with potential industry partners to facilitate the transition to the commercial stage.


NOVA Scientific, Inc.
Sturbridge Technology Park 10 Picker Road
Sturbridge, MA 01566-1251

Proposal Information FY07.1-0711077-II - Combined Solid-State Neutron Gamma High Efficiency Detector
Topic Information H-SB07.1-009 - Improved Solid-State Neutron Detection Devices
Award/Contract Number HSHQDC-08-C-00190

NOVA Scientific proposes Phase II development of a solid-state, high-efficiency neutron detection alternative to 3He gas tubes employing neutron-sensitive microchannel plates (MCPs) containing 10B and/or Gd. This program supports the DNDO development of technologies designed to detect and interdict nuclear weapons or illicit nuclear materials. This solid-state neutron detector would permit operations in wide-ranging environments limited with 3He. The small prototypes resulting from the Phase II effort will be designed and sized to support the Intelligent Personal Radiation Locator (IPRL) hardware. Phase I neutron detection efficiency measurements of > 25 % were rigorously carried out using a 252Cf source. With a surrounding gamma scintillator measuring the instantaneous 478 KeV gamma from the boron-neutron interaction, an electronic coincidence procedure verified a neutron event with high confidence, rejecting spurious counts and interference from gamma photons at a level of 10-4, comparable to the selected 3He tube used as a standard. The objective of Phase II Year 1 is to move the MCP component capability to its projected full potential of 60-75 % detection efficiency for thermalized neutrons from a fast source and develop the surrounding scintillator system configuration to establish a gamma rejection of 10-5 to 10-6. This would effectively match or exceed 3He tube performance. Additionally a high yield, low noise vacuum encapsulation of the MCP and algorithm peak search will be carried out. Year 2 will assemble repetitive prototypes, establish a breadboard electronics power and data package, and carry out an assessment of pre-commercialization readiness for field operations. NOVA Scientific is teaming with several experts for support; St. Gobain Crystals for expertise in high speed scintillators; VPI Engineering for power and readout electronics and packaging; Sensor Sciences for test and characterization support; and American Electro-Optics for vacuum tube encapsulation.


Radiation Monitoring Devices, Inc.
44 Hunt Street
Watertown, MA 02472-4699

Proposal Information FY07.1-0711133-II - Improved Solid-State Neutron Detector
Topic Information H-SB07.1-009 - Improved Solid-State Neutron Detection Devices
Award/Contract Number HSHQDC-08-C-00169

The use and applications of radiological sources, for power, medical, and defense applications, continuously increases with time. Illicit nuclear materials represent a threat for the safety of the American citizens and the detection and interdiction of a nuclear weapon is a national problem that has not been yet solved. This represents an enormous challenge to current detection methods and monitoring technologies that require improvement to demonstrate accurate radiation identification capabilities. Using neutron signatures represents a promising solution, however, such a detection technique requires capabilities of detecting neutrons, both thermal and energetic neutrons, while rejecting effectively background gamma rays. Rugged and low-power neutron detectors are highly desirable for large-scale deployment. This research develops a neutron detector that has the potential of replacing pressurized 3Hetubes and current solid-state detectors with an ultra-compact detector based on CMOS-SSPM (Solid State Photomultipliers) technology. This technology provides a low-power, portable unit that can be mass-produced and deployed in a wireless network on a large scale. The detector is very fast and, in addition, can provide time and spectroscopy information over a wide energy range, including fast neutrons and is, therefore, capable of identifying threatening incidents in real time. 2. Anticipated benefits/Potential Commercialization The proposed design for neutron detection has a strong potential to replace He-3 tubes, and can also replace current neutron solid-state detectors, which are either sensitive to gamma-rays or cannot have high-scale production to form a deployable technology for a detection network. In addition the proposed technology is fast, can provide energy and time information, and can be easily adapted into compact packages with or without remote readout electronics. The direct application of this project is to contribute to the national effort of protecting the United States against terrorism through DNDO related missions. However, this research as a whole and with its diverse components will have a big impact on many other research fields that are directed toward general public benefit. The proposed technology with its timing resolution of sub-ns and sub-um high-spatial resolution has immediate application in thermal neutron radiography used to probe macromolecular structures in protein crystallography and in investigations of new materials. The double-pulse signature of thermal neutrons interacting with boron-loaded plastic readout by PMT's is being used for which is the NASA discovery mission that will explore two complementary protoplanets, Ceres and Vesta, to provide new information on processes by which the planets formed. Replacing the PMT by CMOS-SSPM for this mission will definitely enhance this research since SSPM detectors are ultra-compact devices, rugged and operate at low voltages, which is very desirable for space missions. Speaking of space, investigation of highenergy neutrons in space necessarily requires a new type of detection material since fast neutron detectors are traditionally made of liquid compounds that are considered hazardous cargo for space flights. The proposed technology can be scaled to few more layers of detector segments to detect fast neutrons. This technique can be also used for neutron detection in nuclear waste management and especially in investigating the amount of fissile materials when enclosed in waste containers. Neutron/gamma discrimination, which is also important for such applications will be tested through two different methods in the Phase I effort. These techniques of thermal neutron capture, and photon detection will have direct implication on neutron capture therapy of cancer. Due to the high-spatial resolution, energy information, the large signal to background ratio and the low cost of CMOS SSPM devices, this technology represents a strong candidate for neutron and even medical imaging such as PET, small animal SPECT imagers, x-ray imaging and biomedical applications that are directed toward the diagnosis and treatment of Cancer, the Alzheimer disease and disease progression studies. Last and not least, high-energy proton accelerator facilities have been constructed for application in various fields of study, such as nuclear physics, material science and radiotherapy. In these facilities, it is very important to monitor doses from neutrons which can penetrate radiation shields and contribute dominantly to the doses of workers and members of the Conventional moderator-based survey instruments, rem-counters, are, however, less sensitive to such high-energy neutron. The proposed effort will boost these studies since the techniques of collecting the scintillation photons and reading them out with CMOS integrated readout circuitry can be applied there as well.

Proposal Information FY07.1-0711147-II - New Neutron Detectors with Pulse Shape Discrimination
Topic Information H-SB07.1-009 - Improved Solid-State Neutron Detection Devices
Award/Contract Number HSHQDC-09-C-00129

Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Preventing the spread of nuclear weapons has reached a state of heightened urgency in recent years, especially since the events on September 11, 2001 and its aftermath. One way to passively determine the presence of nuclear weapons is to detect and identify characteristic signatures of highly enriched uranium and weapons grade plutonium. Neutrons and gamma rays are two signatures of these materials. Gamma ray detection techniques are useful because the presence of gamma rays of specific energies can confirm the presence of a particular isotope. This technique however, has one significant drawback: In the presence of dense surrounding material such as lead, gamma ray attenuation can be significant. This can mask the gamma signatures of these special nuclear materials (SNM). Neutrons, on the other hand, easily penetrate dense, high atomic number materials compared to r-rays. Under these circumstances, passive assay techniques based on neutron detection can provide valuable information. When detected, neutrons are direct indicator of presence of spontaneously fissioning isotopes (plutonium and californium) and induced fissions (uranium). At present, there is a real need for a compact, efficient detection system that would allow neutron detection with an ability to discriminate gamma events from neutron events. The goal of the proposed effort is to address this need.
