Law enforcement authorities seeking to detect bioterrorism attacks, doctors diagnosing diseases and regulatory agencies checking product safety may find a new ally in a Lawrence Livermore National Laboratory (LLNL) detection technology.

The advance, known as the Lawrence Livermore Microbial Detection Array (LLMDA), could enable law enforcement, medical professionals and others to detect within 24 hours any virus or bacteria that has been sequenced and included among the array's probes.

Developed between October 2007 and February 2008, the LLMDA detects viruses and bacteria with the use of 388,000 probes that fit in a checkerboard pattern in the middle of a one-inch wide, three-inch long glass slide.

From Texas Instruments (available soon for $49.00): eZ430-Chronos Wireless Watch Development Tool (915 MHz US Version): "The eZ430-Chronos is a highly integrated, wireless development system based for the CC430 in a sports watch. It may be used as a reference platform for watch systems, a personal display for personal area networks, or as a wireless sensor node for remote data collection. Based on the CC430F6137 <1 GHz RF SoC, the eZ430-Chronos is a complete CC430-based development system contained in a watch. This tool features a 96 segment LCD display and provides an integrated pressure sensor and 3-axis accelerometer for motion sensitive control. The integrated wireless feature allows the Chronos to act as a central hub for nearby wireless sensors such as pedometers and heart rate monitors. The eZ430-Chronos offers temperature and battery voltage measurement and is complete with a USB-based CC1111 wireless interface to a PC. The eZ430-Chronos watch may be disassembled to be reprogrammed with a custom application and includes an eZ430 USB programming interface." [More at Ti]

Jing Li, a physical scientist at NASA's Ames Research Center, Moffett Field, Calif., along with other researchers working under the Cell-All program in the Department of Homeland Security's Science and Technology Directorate, developed a proof of concept of new technology that would bring compact, low-cost, low-power, high-speed nanosensor-based chemical sensing capabilities to cell phones.

The device Li developed is about the size of a postage stamp and is designed to be plugged in to an iPhone to collect, process and transmit sensor data. The new device is able to detect and identify low concentrations of airborne ammonia, chlorine gas and methane. The device senses chemicals in the air using a "sample jet" and a multiple-channel silicon-based sensing chip, which consists of 16 nanosensors, and sends detection data to another phone or a computer via telephone communication network or Wi-Fi.

"Usually I write about ham radio. But looking at communication devices of the future from the past, I thought it would be fun to have a Star Trek: The Original Series Bluetooth communicator for a cellphone. I worked with Dave Clausen to hack one together from a toy Star Trek communicator, a Bluetooth module, and a microcontroller. Following are the directions and program to make your own. And of course a video to show how the Star Trek Bluetooth Communicator works."

Getting developing world data with Android and Open Data Kit, Ars Technica

"In the developed world, getting real-time data can be a simple matter: simply carry whatever sensor is required, get the data, and then plug into the local network--you're set. Things aren't so simple in the developing world, where there may not even be a power source available, much less specialized hardware or a network. To help field workers obtain the information they need and integrate it into a data collection system, computer science researchers at the University of Washington have developed the Open Data Kit, which includes server software for aggregation and management, developer tools to create forms, and client software that runs on the Android platform."

In previous work, two platforms have been developed for testing computer-vision algorithms for robotic planetary exploration (McGuire et al. 2004b,2005; Bartolo et al. 2007). The wearable-computer platform has been tested at geological and astrobiological field sites in Spain (Rivas Vaciamadrid and Riba de Santiuste), and the phone-camera has been tested at a geological field site in Malta.

In this work, we (i) apply a Hopfield neural-network algorithm for novelty detection based upon color, (ii) integrate a field-capable digital microscope on the wearable computer platform, (iii) test this novelty detection with the digital microscope at Rivas Vaciamadrid, (iv) develop a Bluetooth communication mode for the phone-camera platform, in order to allow access to a mobile processing computer at the field sites, and (v) test the novelty detection on the Bluetooth-enabled phone-camera connected to a netbook computer at the Mars Desert Research Station in Utah.

News media are invited to see a demonstration of first-generation laboratory prototypes of new technology that would bring chemical sensing capabilities to cell phones on Tuesday, Oct. 27, 2009 at San Diego State University Regional Technology Center, San Diego, Calif.

Jing Li, a physical scientist at NASA's Ames Research Center, Moffett Field, Calif., along with other researchers working under the Cell-All program in the Department of Homeland Security's (DHS) Science and Technology Directorate, will demonstrate their proofs of concept. Li has developed a device, designed to be plugged in to an iPhone, which collects sensor data and sends it to another phone or a computer via telephone communication network or Wi-Fi.
