Torrance, CA 90501-1510

Proposal Information HSHQDC-14-R-00035-H-SB014.2-001-0005-I - Biological Warfare Agents Remediation System
Topic Information H-SB014.2-001 - Decontamination Technologies for Biological Agents
Award/Contract Number HSHQDC-14-C-00051
Abstract

To address the DHS need for a novel technology platform that is non-destructive to common environmental surfaces but capable of destroying a range of biological agents, Physical Optics Corporation (POC) proposes to develop a Biological Warfare Agents Remediation (BIFAR) system based on photocatalytic ionization of hydrogen peroxide inside porous microcarriers. In Phase I, POC will develop, demonstrate and show material compatibility for an innovative, low cost, environmentally-friendly concept for 6-log reduction of a non-hazardous, biological agent simulant, Bacillus thuringiensis (Bt), on three environmental surfaces such as concrete, wood, and galvanized metal. In Phase II, POC plans to optimize the innovative technical approach and demonstrate 6-log reduction in viable biological agent simulants, such as the Sterne strain of Bacillus anthracis, on the following environmental surfaces: concrete, wood, soil, galvanized metal, glass, plastic, and painted wallboard under required environmental conditions and using commercial components. Also, POC will demonstrate a small pilot-scale production process that can produce the innovative decontamination product in a safe and cost-effective manner that can be readily scaled by a qualified manufacturer for cost-effective production of large, commercial quantities. Commercial applications include pest control, mold and fungus removal, and sterilization of medical facilities and sensitive equipment.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-001-0009-I - Photochemical ClO2 Decontaminant for Biological Agent Neutralization
Topic Information H-SB014.2-001 - Decontamination Technologies for Biological Agents
Award/Contract Number HSHQDC-14-C-00049
Abstract

DHS requires the ability to respond to an attack with biological agents. Specifically, it requires a decontaminant to kill anthrax spores on building exteriors and interiors, and other surfaces. In this proposal we describe an innovative bio-agent decon technology that is particularly suitable for decon over wide areas; and as far as we are aware, no other technology in development can be used on such a large scale. This proposed technology has already demonstrated efficacy against chemical warfare agent simulants and anthrax surrogates. In this proposed DHS project, we would adapt and demonstrate a product currently in commercial development to meet the important needs for a national security biological warfare agent decontaminant.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-001-0013-I - Rapid Low-Cost Biological Warefare Decontamination
Topic Information H-SB014.2-001 - Decontamination Technologies for Biological Agents
Award/Contract Number HSHQDC-14-C-00052
Abstract

Lynntech, Inc. proposes the use of a novel oxidant as a powdered concentrate, that when dissolved in water, yields a potent sporicidal solution capable of reducing spores by greater than 6-logs on a variety of surfaces. The sporicidal formulation will be tested on concrete, wood, galvanized metal, glass, plastic and painted wallboard to determine if the formulation will reduce spores but not harm the contacted surfaces. The formulation will include gelling agents to increase the formulation viscosity to better adherence to walls and ceilings for longer contact times. The formulation will also contain additives to increase efficacy of spore coat penetration and long term shelf life. Potential markets include first responders, military, medical and biomedical industry, and agriculture and industrial sectors for clean up and first response remediation. Alternative end user interest might include clandestine drug synthesis laboratory clean-up companies.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-001-0026-I - In situ Production of Biocidal Reactive Oxygen Via Directed Energy
Topic Information H-SB014.2-001 - Decontamination Technologies for Biological Agents
Award/Contract Number HSHQDC-14-C-00050
Abstract

The in situ production of biocidal reactive oxygen via directed energy work will develop a benign, environmentally safe decontamination solution. The effort will demonstrate the potential to produce biocidal reactive oxygen and thermal effects via exposure to radio frequency directed energy at two frequencies to kill bacterial (Bacillus thuringensis) and mold (Penicillium sp.) spores. Controlled experiments will demonstrate comparative kill based on solution and exposure time. A statistical analysis will be conducted on the results. The effect will be demonstrated on three different surfaces (glass, wood, plastic) to evaluate the potential uses of the system. The resulting data will include compositions of the decontamination system and evaluation of two types of radio frequency sources. The commercial applications of the product include hazardous material cleanup, military biological decontamination systems, mold remediation in buildings, and reduction in hospital acquired illnesses via whole room decontamination.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-002-0004-I - Autonomous Detection and Healing of Silent Vulnerabilities
Topic Information H-SB014.2-002 - Automatic Detection and Patching of Vulnerabilities in Embedded Systems
Award/Contract Number HSHQDC-14-C-00056
Abstract

BlueRISC's proposed solution provides a fundamentally new approach to enable autonomous detection of exploitation attempts as well as healing of silent vulnerabilities. It follows a hybrid approach consisting of (i) new static silent vulnerability point and associated path pre-characterization concepts, and (ii) the insertion of minimal and low-overhead runtime support enabled by the vulnerability characterization framework to enable validation, detection and healing at runtime. As opposed to other solutions, which rely on an attacker successfully injecting functionality in order to detect, this solution is also able to detect the exploitation of silent vulnerabilities, which leak information without modifying the system. The solution is CPU and operating system agnostic and thus widely applicable. Initial sectors that will be targeted are the critical infrastructure Energy Sector and the Defense Industrial Base Sector.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-002-0006-I - GenPatcher: Automatically Evolving Invulnerable Systems
Topic Information H-SB014.2-002 - Automatic Detection and Patching of Vulnerabilities in Embedded Systems
Award/Contract Number HSHQDC-14-C-00055
Abstract

Modern civilization relies on a network of embedded devices that are (i) riddled with security vulnerabilities and (ii) remotely hackable. Unfortunately, there seems to be near universal neglect for ensuring the security of these devices. Moreover, the existing IT solutions, such as antivirus software and intrusion-detection systems, do not provide substantial benefits for protection of embedded systems. To address this problem, we propose GenPatcher, a fully automated end-to-end solution for securing embedded-systems software. GenPatcher will integrate (i) GrammaTech's ongoing research on vulnerability discovery and patch evaluation with (ii) recent breakthroughs in genetic program repair. The key advantage of GenPatcher is that it will be able to operate completely autonomously, without requiring human interaction. Thus we expect GenPatcher to significantly reduce the costs of vetting and deploying critical software. GenPatcher will operate directly on software binaries, even in the absence of source code, and thus, will protect equally well newly developed software, third-party codes, and legacy software. We will build GenPatcher to be easily retargetable to different instruction sets to accommodate a variety of platforms employed in the embedded systems domain.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-002-0011-I - Automated Embedded Vulnerability Identification and Exploitation Mitigation System Using FRAK, Symbiote and Autotomic Binary Structure Randomization
Topic Information H-SB014.2-002 - Automatic Detection and Patching of Vulnerabilities in Embedded Systems
Award/Contract Number HSHQDC-14-C-00053
Abstract

We propose to design a novel framework and associated algorithms to combine the state-of-the-art in static firmware vulnerability analysis and mitigation with a suite of novel dynamic defensive techniques powered by Red Balloon Security's software Symbiote technology. While Symbiotes have traditionally been used directly to enforce dynamic firmware integrity attestation in embedded devices, we propose to design new Symbiote payloads capable of not only dynamic attestation, but live attack forensic data collection, analysis and ultimately, live hardening of vulnerable devices based on forensic data collected by other similar deployed devices. Lastly, we propose to design a comprehensive framework for truly integrating all meta-data collected through both static and dynamic analysis components to continuously, and automatically, identify and mitigate vulnerabilities on all protected devices. Such a framework will allow network defenders to: - Maximize vulnerability identification accuracy while minimizing expert human intervention - Minimize reaction time between threat identification and mitigation deployment for proprietary embedded devices - Maximize forensic data collection capabilities on black-box embedded devices - Minimize downtime of vulnerable and compromised devices while drastically increasing the defenders ability to patch vulnerabilities within embedded devices dynamically - Maximize overall embedded security situational awareness across enterprise-level networks of heterogeneous embedded devices We propose to deliver a phase one report that details the component technology designs and time and cost estimates for a phase two contract to implement, test and evaluate these technologies.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-002-0015-I - Automatic Detection and Patching of Vulnerabilities in Embedded Systems
Topic Information H-SB014.2-002 - Automatic Detection and Patching of Vulnerabilities in Embedded Systems
Award/Contract Number HSHQDC-14-C-00054
Abstract

Embedded devices are vulnerable to cyber attacks and their compromise can severely impair critical infrastructure and mission-critical systems. Power Fingerprinting (PFP) is a novel approach for integrity assessment of critical embedded systems which is capable of detecting malicious intrusions at all levels of the execution stack. PFP is based on fine-grained anomaly detection on the processor's power consumption profile, which allows it to leverage signal detection and classification principles to provide a quantitative metric of execution integrity. PFP enables security monitoring and integrity assessment on platforms that would otherwise not have the memory or processing resources necessary to do it. For this Phase I project we will demonstrate the feasibility of using PFP to perform automatic detection of exploited vulnerabilities and malicious intrusion in networked embedded systems. The specific technical objectives include: 1) Demonstrate the feasibility of PFP technology for automatic detection of exploited vulnerabilities and patching on networked embedded platforms; 2) Develop techniques to enable remote PFP monitoring; 3) Develop techniques to deliver patches and updates to the target device and PFP monitor. A PFP-based automatic vulnerability detection represents a dual-use opportunity with a broad range of applications within the military, the federal government, and several commercial enterprises.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-003-0003-I - Algorithmically Accelerated Iterative Reconstruction for Fast and Cost-Effective CT-based Explosive Detection Equipment
Topic Information H-SB014.2-003 - Development of Cost-Effective Iterative Reconstruction Computing Platforms for Computed Tomography (CT)-based Explosive Detection Equipment
Award/Contract Number HSHQDC-14-C-00057
Abstract

Accurate, realtime detection of explosives is a demanding application. High detection accuracy with a low false positive rate is desired. Noise and artifacts in reconstructed images, especially in the presence of metal, degrade the ability of detection algorithms to identify object's shape, volume, and composition. Model-based iterative reconstruction (MBIR) has been demonstrated to improve image quality over conventional direct reconstruction techniques - improving image resolution while suppressing noise and artifacts. The drawback is the significant increase of computation required for image formation, leading to an algorithm that is infeasible: either the reconstruction is too slow, or the hardware required for the desired throughput is too expensive. We will first establish a baseline iterative algorithm matching published state of the art image quality improvements. We will then reduce its computational demands 60 fold via algorithmic speedup. Cornerstone to this effort are the InstaRecon fast hierarchical operators, which reduce the computational complexity of the main computational burden of MBIR. Additional sources of algorithmic acceleration include variable splitting techniques for improved convergence rate, and approximate gradients. We will assess the combination of these algorithmic accelerations with hardware acceleration such as GPUs in the final technical report. Computation is a limiting factor in bringing iterative reconstruction to the market. Only so much hardware acceleration can be used without making cost a prohibitive factor. The algorithmic acceleration proposed here is an essential component of an iterative reconstruction system that can run at the required throughput on a modest hardware platform, making commercial deployment economically feasible.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-003-0004-I - Inversion Engine: A Custom Hardware/Software/Algorithmic Solution for Fast MBIR Imaging
Topic Information H-SB014.2-003 - Development of Cost-Effective Iterative Reconstruction Computing Platforms for Computed Tomography (CT)-based Explosive Detection Equipment
Award/Contract Number HSHQDC-14-C-00058
Abstract

Model-based image reconstruction (MBIR) has been demonstrated to have great potential value in a variety of DHS applications including baggage and cargo CT scanning. However, while MBIR has the potential to reduce artifacts and increase resolution, the computational requirements remain a barrier to its application. High Performance Imaging LLC seeks to create and commercialize the Inverse Engine, a novel integration of algorithms/software/hardware that will reduce the cost and time for computation of MBIR methods to levels feasible for EDS applications. The Inversion Engine will provide a turnkey OEM solution to vendors that will allow them to incorporate MBIR technology into a wide variety of imaging systems, thereby eliminating an important technical and market barrier. The Inversion Engine is designed to be geometry agnostic, so it will efficiently compute the solution to a wide variety of reconstruction problems, including CT systems with either dense or sparse views. HPI's commercialization plan is to license the technology first to TSA vendors that provide systems for screening baggage and cargo. In addition, other fertile markets exist for the Inversion Engine in scientific imaging, industrial inspection, commercial imaging, and medical imaging.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-004-0001-I - Portable Laser Hazard Identification and Monitoring System
Topic Information H-SB014.2-004 - Radiant Laser Exposure Monitoring for Nominal Hazard Zone (NHZ) Evaluation
Award/Contract Number HSHQDC-14-C-00060
Abstract

Laser beams present potentially serious hazards to the human eye. Retinal damage can occur for laser eye exposure to milliwatts power levels. The purpose of this proposed program is to develop a portable system for detecting and measuring radiant exposure resulting from laser beams, and to determine whether the detected radiant exposure levels exceed established maximum permissible exposure (MPE) limits. Spire will utilize commercially available optical radiation detectors in combination with optical filters and appropriate optics to measure the direction and intensity of incoming laser beams, as well as to determine the spectral content of the laser beams and their temporal and radiant characteristics. These measured values will then be automatically compared to ANSI-established MPE limits so that appropriate warnings, together with summary laser characteristics information can alert personnel in the area. Phase I will demonstrate feasibility by completion of the basic system design, fabrication and laboratory demonstration of the primary system components and initial data accumulation electronics and associated software development. Phase II will implement the system design with the goal of comparing incoming laser radiation characteristics with established MPE limits for the various specified spectral bins. In addition to the obvious military personnel protection applications, potential commercial applications for this laser hazard identification and monitoring system fall into the areas of public transportation (protection of aircraft pilots, train, truck and bus operators, naval and commercial sea vessel personnel,) protection of public safety personnel as well as protection of groups or individuals subject to vandalism laser exposure.

Award/Contract Number HSHQDC-14-C-00059
Abstract

The proposal describes a solution offered by SARA, Inc. in response to the problem of developing a Laser Exposure Monitoring System (LEMS) capable of directly measuring laser exposures relative to Maximum Permissible Exposure (MPE) limits and establishing the boundaries of the Nominal Hazard Zones (NHZ). The approach uses multiple sensors to measure the irradiance and spectrum of the laser irradiation and transmit the data to a laptop computer, where dedicated software process the data to calculate MPE and derive NHZ automatically and with minimal operator intervention. In Phase 1, we will develop and demonstrate the functionality of a brass board system operating at UV, Visible and near-IR portions of the spectrum, and will also present design recommendations for the development of the desired prototype system in Phase 2.

Topic Information H-SB014.2-005 - Status Indicator for Downed Power Lines
Award/Contract Number HSHQDC-14-C-00063
Abstract

The proposed SkySight Technologies Downed Power Line Sensor will detect and alert the presence of a downed power line and its energized status through a sensor on the power line. In the event of a downed power line, an alert message is sent via wireless network to the utility provider regarding the lines energized status, while a concurrent visual onsite indicator flashes to alert first responders and others at the scene to the hazard. The serialized sensor will provide information regarding pole location as well. The study will demonstrate the feasibility of a sensor able to provide real-time line status information that a utility provider can use to plan restoration repairs that return power to the greatest number of people by quickly and accurately dispatching crews to locations where unsafe conditions exist. A Technology Readiness Level (TRL) 2 is expected at the beginning of the Phase I effort, with a TRL 4 expected at completion. The Phase II effort will focus on refining the design and building prototypes for operational evaluation and safety/compliance testing. Commercial applications include use by large and small utility companies maintaining the estimated 500,000 miles of high voltage transmissions lines in the United States.

Award/Contract Number HSHQDC-14-C-00064
Abstract

We utilize a very small single chip communication device connected to a micro controller and a GPS receiver to create a network of rugged, inexpensive, very small pole mounted devices. These devices or "nodes" can determine and report which phase line is disconnected and also which end of the lines are down. The exact location of the node that detects a break is also reported along with the date, time and an indication of whether or not the line is energized. A computer at the nearest sub-station is capable of actively sending an email and/or text message to one or more power company contact points to ensure that the closest responder is dispatched. A message is also sent to the central power management facility where a downed indication can be seen on a map display.

Topic Information H-SB014.2-005 - Status Indicator for Downed Power Lines
Award/Contract Number HSHQDC-14-C-00062
Abstract

Severe weather, aging infrastructure, deferred maintenance, and other reasons contribute to calamitous events with regard to uninterrupted power supply to heavily populated urban areas. Not only are power interruptions considered a sign of poor utility infrastructure, but the events can be extremely deadly in consequence to citizens living in proximity. A majority of all power outages happen to occur on the utility and distribution sub-systems, where people live and work. Moreover, the variety of safety hazards from downed powerlines creates an equally serious threat for those working to recover from the damages of a line failure event. Many downed powerlines are first come across by first responders and not power utility maintenance crews, so it is very important to be able to warn them on-site of the imminent danger. Tanner Research proposes to assist in power restoration and recovery efforts in multiple fashions: First, to alert immediately alert proximal citizenry to apparent dangers and cue first responders. Second, to identify when and where a failure is occurring able to isolate the danger and repair it to contain and reduce the potential number of lives affected. Furthermore, with the current global warming weather patterns leading to drought and high fire danger in brush and forest zones, the ability to warn of a downed powerline will reduce potential causes of accidental brush fires. Our proposed concept will not only warn people who are in close proximity, but wirelessly alert the utility company of the specific location and time of the powerline abnormality.

Topic Information H-SB014.2-006 - Field Detection and Analysis for Fire Gases and Particulates
Award/Contract Number HSHQDC-14-C-00072
Abstract

KWJ proposes to develop an ultra-low power and low cost, handheld device for monitoring of post-fire air quality, including DHS target toxic gases, combustion gases, CO2, LEL and particular matter (PM). The proposed device will significantly improve the current air monitoring instrumentation of protecting fire responders from hazard post-fire environment. Current multi-gas analyzers are not suitable for field applications, either providing insufficient toxic gas analysis (only 4-6 gases), or large, heavy and with a slow analysis time. An additional sampler is required to collect PM information. KWJ possesses several patented sensor techniques for manufacturing small, ultralow power (microwatts per sensor) yet high performance gas sensors: printed amperometric sensor, MEMS sensors and compact multi-channel sensor chips. Integrating these innovative gas sensors with a compact PM detector, KWJ will be able to develop a device that offers a broad range of sensing requirements in a single, highly portable and low power package for personnel safety in the post-fire environment. In Phase I, KWJ will thoroughly evaluate commercially available gas sensors and KWJ sensing technique, choose corresponding KWJ advanced sensing technique, select candidates of CO2, LEL and PM detectors, fabricate ultra-small, ultra-low power printed sensors and compare their performance with commercial sensors, and lay out the detailed design of the proposed device. The prototypes of the device will be built in Phase II and tested in the field.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-006-0014-I - Ultra-Small, Low-Cost Hazardous Gas and Particulate Matter Detector Using Novel Chip-Scale Chemical Sensor Technology
Topic Information H-SB014.2-006 - Field Detection and Analysis for Fire Gases and Particulates
Award/Contract Number HSHQDC-14-C-00066
Abstract

The proposed SBIR phase I project will demonstrate a ultra-small, low-power, low-cost solution for detection of toxic gases and particulate matter (PM) in air. Firefighters are exposed to various toxic gases and PM both during active knock-down and overhaul phases of fire operation. Four-gas toxic monitors, commonly used by firefighters, are ineffective due to limited information it can provide, their large footprint, high power consumption, and high operational and maintenance cost. All those detectors are built using mature sensor technologies (such as catalytic, electrochemical, and photo-ionization detectors)and have severe operational and reliability drawbacks. N5 Sensors will demonstrate a chip-scale chemical sensor architecture that is ideally suited for detection of large number of toxic gases. This will be accomplished by our patent-pending innovation in photo-enabled sensing - which combines the selective adsorption properties of multicomponent photocatalytic nanoclusters together with the sensitive transduction capability of microscale photoconductors formed using standard highly scalable microfabrication processes. This key innovation enables the sensors to operate with very little power and be completely free from cross-sensitivity to other gases. By combining our innovated sensor chips with low-cost, commercial-off-the-shell PM detector, we will demonstrate a multi-gas and PM detector that can monitor 13 gases and PM of 2.5 and 10 micrometer aerodynamic diameters, with significant reduction in SWAP (Size-Wight-And-Power) and cost.

Proposal Information HSHQDC-14-R-00035-H-SB014.2-006-0017-I - A Handheld Multi-Gas Sensor Based on Selective Gas Adsorption on Mass Transducers
Topic Information H-SB014.2-006 - Field Detection and Analysis for Fire Gases and Particulates
Award/Contract Number HSHQDC-14-C-00065
Abstract

We propose to develop a portable, rugged, handheld multi-gas sensor that is well within the solicitation requirements. We will leverage a mature class of mass sensors that include, for example: quartz crystal microbalances (QCMs) and capacitive micromachined ultrasonic transducers (CMUTs). These sensors boast extraordinary sensitivity to changes in mass (e.g., 50 femtograms for CMUTs) and are used today in several applications including high resolution ultrasonic imaging and film thickness monitoring. The membranes will be coated with materials that exhibit highly selective uptake of the target gases specified in the solicitation. When the device is exposed to a gas molecule that binds to the coating material the resulting mass change will be detected by the mass sensor. The chemical kinetics of the coatings will be engineered to selectively adsorb and desorb the target gases with sub-10 second response times. We will integrate a commercial particle counter with multiple mass sensors to measure all 12 gases specified in the solicitation. The mass sensors are small and thin (less than 10x10x1 mm) and light (less than 1 gram) and their readout electronics can fit on a standard pc board that is 3 in x 3 in x 0.2 in while consuming 300 mW of power allowing for 17 hours of continuous operation. Because of the extraordinarily small size of our sensor technology, we will be able to use ruggedized packaging to meet the drop test requirement, while still satisfying the target specifications for size, weight, battery life, cost, and response time.
