Techno-advanced lifestyle of smart city: Chicago

Chicago's IQ will be measured by Sensors now...!

The University of Chicago (UChicago) announced that the National Science Foundation has awarded a $3.1 million grant to support the development of Array of Things, an urban sensing instrument that will serve as a fitness tracker for the city. Starting next year, 500 Array of Things (AoT) nodes will measure data on Chicago’s environment, infrastructure and activity to scientifically investigate solutions to urban challenges ranging from air quality to urban flooding. The ultimate goal of this innovative community technology platform is to help make cities cleaner, healthier and more livable.

The grant will support a multidisciplinary team of designers, engineers and scientists at the Computation Institute (a joint initiative of UChicago and Argonne National Laboratory), the School of the Art Institute of Chicago, Northern Illinois University and the University of Illinois at Urbana-Champaign.The Array of Things (AoT) is an urban sensing project, a network of interactive, modular sensor boxes that will be installed around Chicago to collect real-time data on the city’s environment, infrastructure, and activity for research and public use. AoT will essentially serve as a “fitness tracker” for the city, measuring factors that impact livability in Chicago such as climate, air quality and noise.

The nodes will initially measure temperature, barometric pressure, light, vibration, carbon monoxide, nitrogen dioxide, sulfur dioxide, ozone, ambient sound intensity, pedestrian and vehicle traffic, and surface temperature. Continued research and development will help create sensors to monitor other urban factors of interest such as flooding and standing water, precipitation, wind, and pollutants.

Array of Things is interested in monitoring the city’s environment and activity, not individuals. In fact, the technology and policy have been designed to specifically avoid any potential collection of data about individuals, so privacy protection is built into the design of the sensors and into the operating policies. Array of Things will not collect any personal or private information.

The nodes utilize an Argonne-developed technology platform called Waggle, created by Argonne’s Peter Beckman, Rajesh Sankaran and Catlett, that allows for powerful and secure remote processing of measurements before transmission of data to a central server.

Because all of the data will be published openly and without charge, it will also support the development of innovative applications, such as a mobile application that allows a resident to track their exposure to certain air contaminants, or to navigate through the city based on avoiding urban heat islands, poor air quality, or excessive noise and congestion.

In partnership with the City of Chicago, the nodes will be mounted on streetlight traffic signal poles around the city by 2017. Fifty nodes will be installed in early 2016, and the number is expected grow to 200 by the end of 2016 and 500 by the end of 2017. The location of these nodes will be determined in collaboration with the City of Chicago and input from researchers and community members.

Eleven nodes are currently undergoing testing on the University of Chicago campus. Additional funding for the project was provided by the University of Chicago Innovation Fund, Argonne, and the John D. and Catherine T. MacArthur Foundation.

What Is The Array of Things? 

US Air Force to use vibration sensors to detect vehicles in anti-access and denied areas.

Air Force Research Laboratory at Wright-Patterson Air Force Base, Ohio, announced an

upcoming program this week for Vibrometry Interrogation for Battlefield Exploitation
(VIBE). The objective of VIBE is to develop combat identification (CID) automatic
target recognition (ATR) for vibrometry sensor data for use within anti-access/area
denial (A2/AD) environments.

Vibrometry sensors utilize the principal of micro-Doppler measurements between the
sensor and target caused by surface deflections. These deflections are due to vibrations mainly caused by mechanical systems (motors) or transformer hum (magnetostriction) during operation of military and civilian vehicles and equipment. These measurements enhance air-to-ground (A/G) and air-to-air (A/A) remote identification of targets. The
addition of vibration measurement to the sensor suite provides an additional non-imagery based identification modality at ranges where traditional electro-optical imaging is resolution limited. The vibrometry modality also provides unique capabilities in settings where a vibration signature is available such as facility interrogation, power plant assessment, obscured targets, and Battle Damage Assessment (BDA).

One of the VIBE program's key challenges will be to extracting features from vibrometry
signatures that remain consistent, and filter out irrelevant noise. For this project
Air Force researchers are not interested in any proprietary hardware, software, or
data solutions. Instead, the program will focus on basic algorithm development.
Program funding will be about $15 million from 2016 to 2022, researchers say.

Vibration technology based security system has been proposed by NIT-K to secure unmanned level crossings.

Recently, an MoU has been signed between Palakkad division - Southern Railway and ECE department, National Institute of Technology Karnataka, Surathkal on a system to provide advance warning at unmanned level crossings.

NIT department focused on vibration technology  and detailed the approach stating that motion of train generating vibration will be used in this system development where a sensitive vibration sensor/acoustic sensor will be installed on the track or sleeper near the level crossing which be constantly monitored for its output.  Further, the output of the vibration sensor will be monitored by the micro-controller device which will process the readings and infer the presence of the train, its type and velocity. 

This simple system that can detect the presence of the train after sensing the unambiguous presence of the train and can provide an audio-visual warning so that people, vehicles, people and livestock can move away from the location of the level crossing. The system will reset itself for next train detection.
