A.I. Generating Dreams & Turning Wi-Fi Routers Into Cameras to See Through Walls

Jul 3, 2023

0:00
aging the latest paper the one that
0:02
happened even after this which is
0:03
already better uses stable diffusion
0:06
uses the thing that you use to make art
0:09
like what should a thing that you use to
0:10
make art have anything to do with
0:11
reading your brain but of course it goes
0:13
further so in this one they said can
0:16
they understand
0:18
um the inner monologue the things you‘re
0:20
saying to yourself in your own mind my
0:23
dude by the way when you dream your
0:24
dream like your visual cortex runs in
0:26
Reverse so your dreams are no longer
0:28
safe
0:29
um but we‘ll try this so they had people
0:31
watch a video and just narrate what was
0:33
going on in the video in their mind so
0:35
there‘s a woman she gets hit in the back
0:37
she falls over this is what the computer
0:40
reconstructed the person thinking
0:43
see a girl looks just like me get hit in
0:45
the back and then she is knocked off
0:48
so our thoughts like are starting to be
0:51
decoded
0:53
yeah just think about what this means
0:55
for authoritarian States for instance
0:58
or if you want to generate images that
1:00
maximally activate your pleasure sensor
1:03
anything else okay but let‘s keep going
1:04
right to really get the sense of the
1:06
combinatorics of this how about can we
1:08
go from Wi-Fi radio signals you know
1:10
sort of like the Wi-Fi routers in your
1:12
house they‘re bouncing off radio signals
1:14
that work sort of like sonar can you go
1:16
from that to where human beings are to
1:19
images so what they did is they had
1:21
um you know a camera looking at a space
1:24
with people in it
1:25
um that‘s sort of like coming in from
1:26
one eye the other eye is the radio
1:28
signals so sonar from the Wi-Fi router
1:31
and they just learn to predict like this
1:33
is where the human beings are then they
1:35
took away the camera so all the AI had
1:38
was the language of radio signals
1:40
bouncing around a room and this is what
1:43
they‘re able to reconstruct
1:45
Real Time 3D pose estimation right so
1:50
suddenly AI has turned every Wi-Fi
1:53

router into a camera that can work in
1:56
the dark specially tuned for tracking
1:58
living beings
2:01
already

Is Your Router Spying on You?

(January 7, 2025)

What’s probably the most interesting aspect of the sudden focus on WiFi routers is that security experts have been complaining for years that most routers on the market have shoddy security measures and are easy to hack. Perhaps one outcome of the sudden focus on routers will be new government rules demanding better security for all devices.

It’s always a little hard to distinguish politics from reality. Politicians are suddenly lining up to dump on the Chinese, which is easy to do for an issue with no domestic political backlash.

The U.S. Is Trying To Blind Ukraine—By Kicking It Out Of Orbit. It Won’t Work.

Ukraine relied heavily on America’s own large fleet of spacecraft—hundreds of satellites for communication and surveillance—plus commercial space services paid for by the U.S. or other allies.

The satellites helped Ukrainian troops, drones and munitions navigate and communicate, spotted—via radar and camera—Russian forces on the move and traced Russian command networks by detecting their radios.

(20.09.2023)

It‘s only a tiny incremental step towards Musk‘s sweeping vision for his company‘s brain chip. In 2020, Musk promised Neuralink devices could solve numerous neurological conditions, including addiction or memory loss, or restore movement for people with spinal cord injuries. He‘s even promised that one day, a Neuralink brain chip could allow for human-to-human telepathy.

In short, despite Musk‘s grand ambitions, Neuralink still has a lot of work to do to catch up with its competitors — and isn‘t about to completely revolutionize the field just yet.

DER MOBILE TELEVISOR (III): “Boden durchdringender Radar” aus Luftraum und Orbit

(17. Februar 2013)

Die optische Auflösung von Bildern mobiler “Televisoren” (durch Materialien sehender visueller Erfassungsapparaturen) hängt grundsätzlich von der Wellenlänge / Frequenz ab und nimmt mit zunehmender Wellenlänge (d.h.: abnehmender Frequenz) ab.

Für potentiell flächendeckende Durchleuchtung von Metropolen mit ihren tausenden Gebäuden und Kellerräumen bietet sich – wenn auch nicht mit gleicher optischer Auflösung wie bei unmittelbarer Nähe des Zielobjekts und Verwendung von hochfrequenter elektromagnetischer Strahlung – der Einsatz von etwas niedriger frequenten Millimeterwellen aus der Luft an, etwa durch Drohnen. Bereits im September 2008 hatte das U.S.-Militär, nach jahrelanger und in Zeiten des “Antiterrorismus” massiv finanziell geförderter Forschung, an die Presse dringen lassen, man setze in Kriegsgebieten Drohnen mit Überwachungstechnologien ein, die “das Verfolgen von menschlichen Zielen erlauben, selbst wenn sie in Gebäuden oder auf andere Art versteckt sind”.

The Thing (listening device)

The Thing, also known as the Great Seal bug, was one of the first covert listening devices (or „bugs“) to use passive techniques to transmit an audio signal. It was concealed inside a gift given by the Soviet Union to W. Averell Harriman, the United States Ambassador to the Soviet Union, on August 4, 1945. Because it was passive, needing electromagnetic energy from an outside source to become energized and activate, it is considered a predecessor of Radio-Frequency Identification (RFID) technology.

Psyche mission launches as NASA’s first trip to a metal world

(October 13, 2023)

To accomplish the rest of the mission, the van-size spacecraft will rely on its new solar electric propulsion system, powered by Hall-effect thrusters, Oh said. The thrusters will utilize the spacecraft’s large solar arrays and “use electricity to ionize xenon gas and accelerate those charged ions through an electric field to very, very high speeds,” Oh said. (…)

Also along for the ride is the Deep Space Optical Communications technology demonstration, or DSOC. Occurring during the first two years of the journey to Psyche, it will be NASA’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser.

ILLUMA-T

NASA wants to update its existing radio communications system on the International Space Station (ISS) with optical communication technology. Optical communication systems, which use laser beams to transmit information through space, promise the ability to transmit data between a spacecraft and Earth at a much higher rate than radio-frequency systems. Our researchers are designing ILLUMA-T*, a laser terminal that will provide an optical communications link from the ISS to NASA‘s Laser Communications Relay Demonstration satellite, which, in turn, will use optical communications to relay the data from the ISS link to a ground terminal at a rate 10 to 100 times faster than current radio frequency communications systems.

NASA’s Laser Communications Relay: A Year of Experimentation

(Jun 28, 2023)

The Laser Communications Relay Demonstration (LCRD) uses infrared light, or invisible lasers, to transmit and receive signals rather than radio wave systems conventionally used on spacecraft. Infrared light’s tight wavelengths allow space missions to pack significantly more data – 10 to 100 times more – into a single transmission. More data means more discoveries.

Now, at the halfway point in its experimentation phase, LCRD has shown laser communications’ significant advantages over traditional radio wave systems.

Giant gravitational waves: why scientists are so excited

On 29 June, four separate teams of scientists made an announcement1–4 that promises to shake up astrophysics: they had seen strong hints of very long gravitational waves warping the Galaxy.

Gravitational waves are ripples in the fabric of space-time that are generated when large masses accelerate. They were first detected in 2015, but the latest evidence hints at ‘monster’ ripples with wavelengths of 0.3 parsecs (1 light year) or more; the waves detected until now have wavelengths of tens to hundreds of kilometres.

Here Nature reports what these monster gravitational waves could mean for our understanding of the cosmos, and how the field could evolve.

The Cosmos Is Thrumming With Gravitational Waves, Astronomers Find

(June 28, 2023)

The scientists strongly suspect that these gravitational waves are the collective echo of pairs of supermassive black holes — thousands of them, some as massive as a billion suns, sitting at the hearts of ancient galaxies up to 10 billion light-years away — as they slowly merge and generate ripples in space-time.

“I like to think of it as a choir, or an orchestra,” said Xavier Siemens, a physicist at Oregon State University who is part of the North American Nanohertz Observatory for Gravitational Waves, or NANOGrav, collaboration, which led the effort. Each pair of supermassive black holes is generating a different note, Dr. Siemens said, “and what we’re receiving is the sum of all those signals at once.”

Searching for the Nano-Hertz Stochastic Gravitational Wave Background with the Chinese Pulsar Timing Array Data Release I

(Published 29 June 2023)

Observing and timing a group of millisecond pulsars with high rotational stability enables the direct detection of gravitational waves (GWs). The GW signals can be identified from the spatial correlations encoded in the times-of-arrival of widely spaced pulsar-pairs. The Chinese Pulsar Timing Array (CPTA) is a collaboration aiming at the direct GW detection with observations carried out using Chinese radio telescopes. This short article serves as a „table of contents“ for a forthcoming series of papers related to the CPTA Data Release 1 (CPTA DR1) which uses observations from the Five-hundred-meter Aperture Spherical radio Telescope. (…)

A Pulsar Timing Array (PTA; Foster & Backer 1990) is an array of pulsars, which are regularly observed. The times-of-arrival (TOAs) are measured for pulses that we see beams of electromagnetic waves emitted by the pulsars sweeping over the Earth. As the directions of the radiation beam and the pulsar rotational axis do not coincide, we observe this radiation as regular pulses synchronized to the pulsar rotation (Gold 1969).

A global environmental crisis 42,000 years ago

(19 Feb 2021)

Do terrestrial geomagnetic field reversals have an effect on Earth‘s climate? Cooper et al. created a precisely dated radiocarbon record around the time of the Laschamps geomagnetic reversal about 41,000 years ago from the rings of New Zealand swamp kauri trees. This record reveals a substantial increase in the carbon-14 content of the atmosphere culminating during the period of weakening magnetic field strength preceding the polarity switch. The authors modeled the consequences of this event and concluded that the geomagnetic field minimum caused substantial changes in atmospheric ozone concentration that drove synchronous global climate and environmental shifts.

(…)

We precisely characterize the geomagnetic reversal and perform global chemistry-climate modeling and detailed radiocarbon dating of paleoenvironmental records to investigate impacts. We find that geomagnetic field minima ~42 ka, in combination with Grand Solar Minima, caused substantial changes in atmospheric ozone concentration and circulation, driving synchronous global climate shifts that caused major environmental changes, extinction events, and transformations in the archaeological record.
