Military researchers eye electro-optical sensors with machine learning algorithms for defense applications:  ARLINGTON, Va. –  U.S. military researchers are asking industry to develop a new kind of camera and digital signal processing to enable intelligent  electro-optical   sensors for tactical military applications.  Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., issued a broad agency announcement on Friday (HR001121S0001) for the Fast Event-based Neuromorphic Camera and Electronics (FENCE) program.  DARPA FENCE seeks to develop and demonstrate a low-latency, low-power, event-based camera and a new class of digital signal processing and   machine learning   algorithms that use combined spatial and temporal information to enable intelligent sensors for tactical military applications . Neuromorphic describes silicon circuits that mimic brain operation; it exhibits low latency, sparse output , and extreme...

Optical Sensors Advancing Precision in Agricultural Production

Image
Optical Sensors Advancing Precision in Agricultural Production: Agricultural production, already incredibly efficient in much of the developed world, is increasing each year — this is a necessity to feed the 9+ billion people expected on the planet by 2050. A great example of productivity gains is in corn (i.e., maize, Zea mays). One of the most productive crops, corn’s yield has increased sevenfold over the last 100 years in the U.S., meaning that seven times less land is needed to feed the same number of people 1 .  While favorable soils and weather have always played a central role in agriculture productivity, the increases in productivity have been driven by farmers ’ use and adaptation of improved technologies . Despite past successes, agriculture continues to be challenged to “produce more with less” with farm inputs such as phosphorus and irrigation water , which are decreasing in availability and increasing in costs. These challenges are compounded by a changing climate and...

The Schematic Diagram of Automotive Sensor Signal Conditioning

Image
The Schematic Diagram of Automotive Sensor Signal Conditioning   The vehicle sensor is an input device of the automobile computer system. It converts the car’s operating conditions into electrical signals and send to computer, such as vehicle speed, medium temperature, engine operating conditions, etc. There are many vehicle sensors, when you analyze a sensor failure. You should not only consider the sensor itself, but consider the whole circuit. Therefore, when you are looking for a failure, in addition to inspecting the sensor, you should check the wiring harness, the   connector   and the relevant circuit between the sensor and the electronic control unit. The ZSSC3170 from ZMDI company, is an  automotive  sensor signal conditioner which integrates PWM interface, with a maximum  analog  gain of 420 and extended offset compensation: 1. The device is compatible with the forest indicator 1.3 / 2.0 / 2.1; 2. Data conversion rate is up to 430Hz; 3. ...

Sensor Technologies for Intelligent Transportation System

Image
Sensor Technologies for Intelligent Transportation System   Modern society faces serious problems with transportation systems , including but not limited to traffic congestion , safety, and pollution . Information communication technologies have gained increasing attention and importance in modern transportation systems. Automotive manufacturers are developing in-vehicle sensors and their applications in different areas including safety, traffic management, and infotainment. Government institutions are implementing roadside infrastructures such as cameras and sensors to collect data about environmental and traffic conditions. By seamlessly integrating vehicles and sensing devices , their sensing and communication capabilities can be leveraged to achieve smart and intelligent transportation systems. We discuss how sensor technology can be integrated with the transportation infrastructure to achieve a sustainable Intelligent Transportation System (ITS) and how safety, traffic control...

Save electricity with motion sensors

Image
  Save electricity with motion sensors: Motion sensors  can help you save on your bill without your having to do anything. They are responsible for turning on the light when they sense a presence and automatically turning it off when it is no longer there. This way you avoid the risk, and expense, of having lights on where you don’t need them. When we think of  home automation   it is normal to imagine a sophisticated house controlled by a “digital brain” that automatically responds to our needs. Well, you too can enjoy hassle-free home automation with something as simple as motion sensors to   turn lights on and off. Lighting when needed Lighting empty spaces   is an expense, even with energy efficient light bulbs. Especially those you just walk through or where you stay only for a short time but where the lights may remain on for a long time. More or less until you notice and turn them off. Long corridors, dressing rooms, bathrooms, inside wardrobes and c...

Application-specific vibration pre-processing chip

Image
  POLYN Technology has introduced VibroSense , a Tiny AI chip for vibration monitoring sensor nodes. VibroSense greatly reduces the amount of sensor data transmitted to the cloud, saving on power consumption and enabling energy - harvesting designs .                                      VibroSense extracts unique patterns from sensor’s raw signal and passes the valuable data only for classification at the next compute point. It smoothly and simply integrates into existing solutions to improve the ROI and OPEX of the deployment. It is particularly suited to Industry 4.0 applications. “PdM solutions usually require cloud services and are resource-hungry,” said Eugene Zetserov, Vice President of Marketing for POLYN . “The sensor node consumes a lot of electricity on vibration data transmission. Collecting data from many sensors requires considerable resources such as the sensor node itself,...

Tiny smart waste sensor cuts emissions significantly

Image
  OSCAR from adhoc networks is the world’s smallest, smart, waste sensor module, measuring a mere 71- x 43- x 28-mm. The optics can measure up to 4m within a container with a cone angle of 27° to determine the fill level. The company’s waste sensor modules are the key to its automated, fill-level detection and collection scheduling technology for local authorities and private companies that can reduce unnecessary collection trips to containers that are only partly filled.                  The optical sensor in the device monitors the fill level in the waste container and sends that data for centralised processing to enable a schedule of waste collection to be created. Because waste is only collected when the containers are actually full, CO 2   emissions by the collection fleet can be reduced by up to 40% . “Knowing the exact level in every container ensures that there are no wasted collections of part filled containers and, even m...

Bengaluru astronomers help develop low-cost star sensors for satellites

Image
  BENGALURU: Astronomers from the city-based Indian Institute of Astrophysics (IIA) and their collaborators have developed a low-cost star sensor that can help small CubeSat-class  satellites  find their orientation in space. The instrument, Starberry- Sense , built using commercially available off-the-shelf (COTS) components, is ready for launch on the Polar  Satellite Launch  Vehicle’s stage-4 orbital platform and can be used for CubeSats and other small satellite missions in the future. Pointing out that in recent years, CubeSats and small satellite missions have gained a great deal of popularity, astronomers said these missions utilise commercially available components for their design and development, but the typical cost of a commercially available star sensor often exceeds the total budget for a CubeSat. Starberry -Sense can help address this issue. “The sensor developed by researchers at IIA and their collaborators costs less than 10% of those available...
