Raytheon to create DARPA’s airborne “wireless internet for energy”

Posted by in categories: internet, robotics/AI

DARPA has tapped Raytheon to design and develop a wireless, airborne relay system to “deliver energy into contested environments,” as part of its Energy Web Dominance program, in which DARPA wants to be able to power anything from nearly anywhere.

Under a two-year, US$10 million DARPA contract, Raytheon will create a Persistent Optical Wireless Energy Relay (POWER) system, using a series of high altitude unmanned aircraft equipped with laser-based power receiving and transmitting capabilities. Energy will be beamed up to high altitude, then relayed across however many jumps are necessary to reach the target area.

That target might be on the ground, or it might itself be another autonomous aerial platform, in which case it could stay airborne as long as necessary, its batteries being constantly charged from afar.

Hong Kong develops world’s first antenna for ultra-secure 6G

Posted by in categories: computing, internet, physics

Researchers call it the ‘Holy Grail’ for physicists and engineers.


A group of researchers, led by Professor Chan Chi-hou from the City University of Hong Kong, created a special antenna that can control all five important aspects of electromagnetic waves using computer software.

The antenna, which they have named ’microwave universal metasurface antenna,’ is capable of dynamically, simultaneously, independently, and precisely manipulating all the essential properties of electromagnetic waves through software control.

Amazon tests space laser to transmit internet, aims 3,236 satellite web

Posted by in categories: internet, satellites

Project Kuiper seeks to deploy a swarm of small satellites into low Earth orbit (LEO) to enhance global broadband access, particularly to remote locations of the planet.


Amazon’s Project Kuiper initiative has marked a significant achievement with the successful in-orbit testing of a critical technology known as optical inter-satellite links (OISL).

The Emergence Of Smart Cities In The Digital Era

Posted by in categories: internet, nanotechnology, robotics/AI, security, sustainability, wearables

By Chuck Brooks


Realizing the potential of Smart Cities will require public-private cooperation and security by design.

The idea of smart cities is starting to take shape as the digital era develops. A city that has developed a public-private infrastructure to support waste management, energy, transportation, water resources, smart building technology, sustainability, security operations and citizen services is referred to as a “smart city”. Realizing the potential of Smart Cities will require public-private cooperation and security by design.

Starlink triples its internet traffic amid geopolitical tensions

Posted by in categories: internet, satellites

Starlink has around 5,000 satellites in orbit, far more than any other provider.


According to Cloudflare, Starlink’s internet traffic has nearly tripled in 2023 compared to 2022. In the US, the traffic has grown by 250%, while in Brazil, where Starlink launched last year, the traffic has surged by 1700%.

Study: Customized GPT has security vulnerability

Posted by in categories: internet, robotics/AI, security

One month after OpenAI unveiled a program that allows users to easily create their own customized ChatGPT programs, a research team at Northwestern University is warning of a “significant security vulnerability” that could lead to leaked data.

In November, OpenAI announced ChatGPT subscribers could create custom GPTs as easily “as starting a conversation, giving it instructions and extra knowledge, and picking what it can do, like searching the web, making images or analyzing data.” They boasted of its simplicity and emphasized that no coding skills are required.

“This democratization of AI technology has fostered a community of builders, ranging from educators to enthusiasts, who contribute to the growing repository of specialized GPTs,” said Jiahao Yu, a second-year doctoral student at Northwestern specializing in secure machine learning. But, he cautioned, “the high utility of these custom GPTs, the instruction-following nature of these models presents new challenges in .”

A new model that allows robots to re-identify and follow human users

Posted by in categories: information science, internet, robotics/AI

In recent years, roboticists and computer scientists have introduced various new computational tools that could improve interactions between robots and humans in real-world settings. The overreaching goal of these tools is to make robots more responsive and attuned to the users they are assisting, which could in turn facilitate their widespread adoption.

Researchers at Leonardo Labs and the Italian Institute of Technology (IIT) in Italy recently introduced a new computational framework that allows robots to recognize specific users and follow them around within a given environment. This framework, introduced in a paper published as part of the 2023 IEEE International Conference on Advanced Robotics and Its Social Impacts (ARSO), allows robots re-identify users in their surroundings, while also performing specific actions in response to performed by the users.

“We aimed to create a ground-breaking demonstration to attract stakeholders to our laboratories,” Federico Rollo, one of the researchers who carried out the study, told Tech Xplore. “The Person-Following robot is a prevalent application found in many commercial mobile robots, especially in industrial environments or for assisting individuals. Typically, such algorithms use external Bluetooth or Wi-Fi emitters, which can interfere with other sensors and the user is required to carry.”
