Military Sensor Inspires Instrument to Search for Life on Mars

This artist’s rendition shows how BILI could operate on Mars. (NASA) A sensing technique used by the U.S. military currently to remotely monitor the air to detect potentially life-threatening chemicals, toxins, and pathogens has inspired a new instrument that could “sniff” for life on Mars and other targets in the solar system.

Algorithms for Change Point Analysis

Given a series of data, change point analysis involves detecting the number and location of change points, locations in the data where some feature, for example the mean, changes. This has applications in a wide variety of areas, including: Finance, quality control, genetics, environmental studies and medicine. - A brief description linking to NAG Library routines that may help in your applications.

Thermocouple Simulator

The P470 thermocouple simulator is the latest in Highland Technology’s (San Francisco, CA) line of USB and Ethernet-connected Bench-top modules. It features 8 isolated channels, each capable of simulating J, K, E, T, R, S, B, and N thermocouple types, or outputting voltage in a range of ±100 millivolts with 20-bits of resolution. It can also simulate an open thermocouple. Two precision external RTD signal conditioners plus one internal RTD are provided for reference junction temperature sensing.

Edward Chow, AUDREY Program Manager, Jet Propulsion Laboratory, Pasadena, CA

Edward Chow leads the development of AUDREY, the Assistant for Understanding Data through Reasoning, Extraction, and sYnthesis. The artificial-intelligence system captures a variety of sensor data, including gases, temperature, and location signals. By sending alerts through a mobile device or head-mounted display, AUDREY could soon be used to guide first responders through dangerous conditions.

New System Allows Buildings to 'Sense' Internal Damage

Researchers at the Massachusetts Institute of Technology have developed a computational model that makes sense of the ambient vibrations that travel up a structure as trucks and other forces rumble by. By picking out specific features in the noise that give indications of a building’s stability, the model may be used to continuously monitor a building for signs of damage or mechanical stress.
