The Enhanced Decision Analysis for Counter-Terrorism (EDACT) decision fusion tool was designed to assist with surveillance within crowded public areas e.g. shopping centres and sporting events. The tool combines the decisions from multiple security sensors to improve detection rates and reduce false alarms.

An innovative Dstl developed collimator offers benefits to security, medical or industrial x-ray scanning applications. The prolate spheroid twisted slit collimator design allows for higher image quality, lighter and more portable high-energy radiation and particle beam systems.

The new LFT method can revolutionise forensic fingerprint analysis as it enables fingerprints to be identified on items that previously would not have been recoverable. The approach is quick, low cost and does not require any additional dyes to enable visualisation.

Large vertical omnidirectional antenna types are cumbersome and prone to snagging on vegetation and building entrances. A new antenna system has been developed offering smaller size, improved freedom of manoeuvre allied with enhanced field performance.

A digital forensic triage tool that uses statistical techniques along with machine learning to improve the efficiency of identifying potential data of interest during digital forensic investigation.

Matisse is an image exploitation tool used to help the MOD analyse operational imagery.
The algorithms allow registration (alignment of multiple images of an area), change detection (identifying potential changes between images of the same area) and object identification.  The Matisse package consists of many complementary algorithms that are tailored to specific problems, e.g. matching two images with very different observation angles.

Novel video face recognition software for improving detection from poor quality footage.
Current face detection and recognition methods can work well for high quality video with little or no clutter. However, low quality and more challenging video data results are less satisfactory.
This system provides highly accurate tracking of individual faces in a video stream, increasing identification rates.

The analysis of complex DNA mixtures containing three or more DNA profiles is a challenge in forensic DNA analysis.  Asunder is a proprietary method for interrogating mixtures of nucleic acids, it can identify the number of contributors in a mixture and their DNA profile, without any knowledge of the contributors or the contributors’ genotypes. Results have shown significant gains over existing methods of analysis.

A new concept for bi-static synthetic aperture radar (SAR), with a transmit-only satellite component, an airborne rebroadcasting and a ground based image processing component. 
This allows for a major increase in the performance of the satellite component, and significantly reduced cost of the processing component through the avoidance of space qualification of the computing power required to decode the SAR image.

Dstl has developed an assay method for detecting the presence of particular nucleic acid
sequences which may be adapted to quantify the amount of the target sequence in a sample.
Using an assay of this type, a fluorescent label becomes incorporated only into the amplification
product allowing delivery of higher specificity and faster detection of target nucleic acids for
methods such as qPCR.

A means to reduce the adverse effects of bright light sources on image intensification devices as used in night vision sensors.  Dstl have developed an electro-optic protection measure (EOPM) that can be applied to an image intensification tube that employs simple material layers and control electronics that can spatially limit the photo-cathode response for bright areas in an imaged scene.

Saturation and blooming effects caused by high intensity light sources such as sunlight, welding arc, car head lamps or lasers if directed at an optical system or device, are a common problem.  They can cause degradation of image quality, loss of situational awareness for the user and often damage to the sensor pixel array. This invention relates to a charge transfer type imaging sensor that limits the transmission of radiation from high intensity light sources.

One of the major problems with matching measured signals to model signals is that the matching effectiveness can be badly compromised in the presence of noise in the measured signal. The NAFM method operates on statistical features of the signals, rather than the actual waveform shapes of the signals. The NAFM method can deliver a significant improvement in matching accuracy, particularly when large or varying amounts of noise are present in the measured signal, as is typical with the use of voice biometrics for mobile consumer devices.

Lasers are a growing threat to the safety of commercial aviation, with over 3000 laser incidents being reported in the U.S. during 2012. However, Laser Event Recorders (LERs) can capture evidence of laser incidents and a new application, LERapp, has been developed as a low cost and rapidly deployable means of detecting and characterising such incidents. Its use as an intelligence gathering tool has the potential to enhance aviation safety.

CDCAT provides a methodology and scoring system for cyber defence preparedness. The development draws significantly on government and industry and consolidates the most effective best practices. Results are presented in a format consistent with the industry standard for IT service management; ITIL offering a potentially huge market to interact with. CDCAT is available from APMG

The Dstl Integrated Audio-Visual Acoustic Detection has been developed to assist sonar operators by automatically analysing auditory information and presenting it as visual markers, simplifying complex sound detection and identification.

Super Bainite steel is a high performance armour steel, following live fire trials it has been demonstrated to have a hardness matching that of alternative high hardness armour steels, and some ceramic armours, at a much reduced cost.

This invention relates to a nonlinear optical device and more particularly to an optically addressed light valve (see below) suitable for selectively limiting the transmission of radiation from high intensity light sources.

An optically addressed light valve suitable for selectively limiting the transmission of radiation from high intensity light sources independent of wavelength using a liquid crystal cell and a photoconductive material (vanadium doped silicone carbide). Originally designed to prevent ‘dazzle’ of light sensors its applications now include protection from sources such as sunlight, arc welding, head lights; or lasers.

A robust and easy to use device has been developed for swabbing surfaces and the sample run on several different lateral flow test strips. A range of materials from explosives to bacterial contamination can be tested for. The sample is retained in the device for subsequent analysis, or as forensic evidence.

An instrument that can deliver reagent-free, real-time, continuous monitoring of bio-aerosols. This could be used for monitoring of bio-aerosol loads at composting sites, detecting indoor mould spores, environmental research or pharmaceutical clean rooms.

The rodenticide market is dominated by anticoagulant products.  However, due to issues such as humaneness, toxicity, resistance and safety there is increasing pressure to develop new products and find alternatives. A selective, safe, biological based, product would address many of these concerns.

Airborne biological threats pose a real and serious concern for both Departments of Defence and the Homeland Security markets.  Threats range from anthrax spores to biological toxins. Current methods to detect their presence are all liquid based (e.g. PCR, immunoassays).  Potential threat agents need to be efficiently extracted from the airborne state for onward liquid-based analysis, a potential threat detected by a “trigger” can then be assessed.

Significant improvements to the performance of Global Navigation Satellite Systems (GNSS) can be achieved by advances in the modulation techniques of the satellites transmitted baseline signal.  Interoperability is also a key benefit between the GPSIII, Galileo and other networks.

Diagnosed cases of sepsis are exceeding 18 million a year with 1,400 patients dying daily in the developed world. New technologies are urgently required to allow for earlier detection of patients with, or at risk of, sepsis. The described technology allows for the pre-symptomatic diagnosis of sepsis, differentiating the approach from those in current use or development.
