I'll be presenting this work at EHSM: http://ehsm.eu/nnI built an X-ray backscatter imaging system from parts found on eBay. This system works by scanning a very thin beam of X-rays across the target, and measures the amount of backscatter for a given beam position. The beam is scanned mechanically by a rotating chopper (collimator) wheel, and by tilting the rotating wheel on an orthogonal axis. The output image is generated on an oscilloscope by matching the horizontal scan speed to the rotating wheel, and using a potentiometer to measure the vertical axis position. The scope's brightness (z axis) is controlled by the amount of backscatter signal received by a large-area detector. Thus, the image is constructed bit by bit. I used a long-exposure shutter on my camera to see the image formed by the moving oscilloscope trace.nnhttp://www.google.com/patents/US5181234 Less

I just used a respec token to get the incendiary ammo. I decided to get what I thought I wanted originally, the Backscatter Optic. Had I known that the incendiary ammo was only for the LMG's, it would have been a no brainer. Hope this helps if you're trying to decide, since the firing range doesn't do the Backscatter Optic any favors. Less

We present Wi-Fi Backscatter, a novel communication system that bridges RF-powered devices with the Internet. Specifically, we show that it is possible to reuse existing Wi-Fi infrastructure to provide Internet connectivity to RF-powered devices. We believe that this new capability can pave the way for the rapid deployment and adoption of RF-powered devices and achieve ubiquitous connectivity via nearby mobile devices that are Wi-Fi enabled.

The MINI Z system is ideal for security and public safety officials for multiple applications. Examples of areas of application include:nnPublic Safety: Quick screening of unattended and suspicious bags and packages for potential terrorist threats in public spaces.nnBorder and Security Checkpoints: Inspecting vehicle bumpers, tires, panels, and interiors for explosives, plastic weapons, and other concealed threats and contraband.nnDrug Enforcement: Investigating suspected drug labs for drugs or currency.nnEvent Security: Screening hand baggage and deliveries to ensure public safety.nnVIP Security: Security sweeps of meeting rooms and furniture for organic threats and IEDs to ensure personnel safety.nnMaritime Security: Screening the hulls and bulkheads of suspected drug running boats for contraband or narcotics.nnGeneral Aviation Security: Inspecting the seats, compartments, and panels of small planes for hidden contraband.nnnMINI Z — the World's First Handheld Z Backscatter® Imaging System:nnScans in Places Other Systems Can't Reach: The MINI Z system is a compact, single-sided imager that can be used to scan objects in hard-to-reach areas, such as unattended bags, backpacks, or packages in a subway or bus. Unlike density meters, trace detectors, or portable transmission X-ray systems, the MINI Z system produces an easy-to-interpret image to quickly detect organic threats and contraband behind non-metallic surfaces.nnUnsurpassed detection of organic threats: The MINI Z handheld system uses AS&E's signature Z Backscatter technology, an advanced X-ray imaging technology that produces a real-time image of the scan target, highlighting organic materials that transmission X-ray systems can miss, such as explosives, currency, and drugs.nnAn easy to use, all-in-one imaging system: The MINI Z system is self-contained and does not require set-up, enabling immediate operation. The operator controls the scanning function using a simple, intuitive GUI on the system's dedicated tablet, upon which an image of the scanned target appears in real-time.nnSafe, secure and dependable operation: The MINI Z system is safe for operators, bystanders, and the environment. The system's X-ray dose conforms to the appropriate ANSI, ICRP, NCRP, and EURATOM radiation safety standards. Although the MINI Z is a low-energy and low-dose Z Backscatter system, it is not designed to scan people. The MINI Z system must be used in accordance with the manufacturer's instructions as well as applicable laws and regulations. Less

A woman who was the victim of a brutal rape underwent a "horrific" experience at the hands of TSA agents this past weekend at Fort Lauderdale-Hollywood International Airport which ended up with her checking into a psychiatric ward.nnThe woman's husband, posted an account of his wife's experience on the Flyer Talk website.nnHis wife had been subjected to a violent sexual assault and death threats at the hands of three men in Florida five years previously, an experience that led to her committing self-harm and being forced to take medication and attend therapy sessions.nnTraveling out of Florida due to a death in the family, his wife was asked to go through a backscatter x-ray device. When she said she would like to opt out, the TSA agent graphically described to her how "they will need to touch your privates," a threat routinely used by TSA screeners to intimidate people into going through the body scanner.nn"That just about did it for my wife, and she started shaking, sweating, and ended up going through the backscatter," the man wrote.nnHowever, despite passing through the x-ray device, TSA agents claimed an "anomaly" in the woman's bra mandated she be patted down on her breasts.nhttp://www.infowars.com/rape-victim-traumatized-by-horrific-tsa-experience/nby Paul Joseph Watsonnhttp://www.infowars.com/nhttp://www.planetinfowars.com/n[Support infowars and spread the news]nhttp://www.infowarsstore.com/ Less

Smart Laser-Scanner for 3D Human-Machine InterfacenAlvaro Cassinelli, Stephane Perrin, Masatoshi Ishikawa, University of Tokyo, JapannThe problem of tracking hands and fingers on natural scenes has received much attention using passive acquisition vision systems and computationally intense image processing. We are currently studying a simple active tracking system using a laser diode, steering mirrors, and a single non-imaging detector, which is capable of acquiring three dimensional coordinates in real time without the need of any image processing at all. Essentially, it is a smart rangefinder scanner that instead of continuously scanning over the full field of view restricts its scanning area, on the basis of a real-time analysis of the backscattered signal, to a very narrow window precisely the size of the target. The complexity of the whole setup is equivalent to that of a portable laser-based barcode reader, making the system compatible with wearable computers. Less

A study that on the surface appears to be independent has claimed that there are no safety concerns regarding radiation firing body scanners used by the TSA in the nation's airports. However, the research is based purely on old data that was released by the federal agency itself.nnThe LA Times reports today that the study, conducted by assistant professor of biomedical engineering Taly Gilat Schmidt of the Marquette University College of Engineering, has found that the scanners "do not expose passengers to dangerous levels of radiation."nnThe report notes that Schmidt's "new independent analysis" found that "the radiation levels are considerably lower than those of other X-ray procedures such as mammograms."nnSchmidt's findings are due to be published in the Medical Physics journal next month, and will surely be lauded by the TSA, which has sought to fend off constant criticism from concerned scientists and experts who have warned that the radiation from backscatter scanners subjects passengers to an increased risk of cancers.nnHowever, even the LA Times report itself admits that the analysis will likely not allay those concerns because, once again, no independent testing of the body scanners was undertaken.nnAs the report notes, "Schmidt, did not test the actual machines. Instead, she based her conclusions on scanner radiation data released publicly by the TSA."nhttp://www.infowars.com/another-bogus-study-claims-irradiating-tsa-body-scanners-are-safe/nby Steve Watsonnnhttp://www.infowars.com/nhttp://www.prisonplanet.tv/nhttp://twitter.com/#!/RealAlexJonesnhttp://www.facebook.com/AlexanderEmerikJonesn[Check out Alex's New Social Network-'Planet Infowars'nhttp://planet.infowars.com/ Less
