Reborn in 2010, the AI ​​in my mind is too powerful.

Chen Yiran had already made arrangements for the simpler things, such as going to Hitachi Metals to customize an exceptionally extravagant permalloy shielding shell.

For vibration isolation, they partnered with the American company Technical Manufacturing Corporation, a global leader in vibration isolation platforms for electron microscopes, semiconductor lithography machines, and laser interferometers.

Their STACCIS series of active air-bearing vibration isolation platforms can attenuate ground vibrations starting from 0.6Hz, providing effective vibration isolation for subways, ocean waves, and island infrastructure construction.

Of course, Chen Yiran still spent money to have them make a more special high-performance version.

The main equipment used in the experiment depends on the experimental method.

Chen Yiran was not prepared to conduct invasive experiments on himself, so he only had three technical routes to choose from: scalp electrodes, functional magnetic resonance imaging, and MEG magnetoencephalography, to see what was special about his brain.

The scalp electrode was excluded because its precision was too poor.

Functional MRI has decent accuracy, accurately locating which brain region is active (at the millimeter level), but it often requires lying still in the lab for two hours to be scanned, resulting in very little data and high latency.

Therefore, MEG (Magnetic Electroencephalography) is the only option. It is a non-invasive detection technology that achieves brain function imaging by detecting the weak magnetic field generated by the electrical current of neurons.

In 1968, the laboratory first used a superconducting magnetometer to measure the magnetic field changes of the human brain's alpha rhythm, marking the birth of MEG magnetoencephalography (MEG) technology.

Then came the superconducting quantum interference device, a flux sensor that converts magnetic flux into voltage.

MEG (Magnetic Electroencephalography) began to develop further, and finally began to be used clinically in 1990.

This technology is commonly used for epileptic focus localization, detection of ischemic penumbra in cerebral infarction, analysis of abnormal thalamic conduction in Parkinson's disease, and plays an important role in the localization of functional areas in neurosurgery.

It also supports language learning, memory mechanism research and brain-computer interface development. Equipped with a high-fidelity audiovisual stimulation system and behavioral workstation, it can conduct high spatiotemporal precision monitoring of whole-brain neural activity.

The only drawback is that it requires a superconducting quantum interference device cooled by liquid helium and a dedicated room that is completely shielded from electromagnetic interference, which would make the cost relatively high.

However, cost is not a problem at all for the super-rich.

However, the superconducting quantum interference device needs to be replaced because this technology requires liquid helium cooling, and the sensor cannot be placed close to the scalp.

Chen Yiran first set his sights on a technology that had just emerged in 2008: the diamond nitrogen-vacancy central magnetometer.

In a diamond crystal, replacing a carbon atom with a nitrogen atom creates a nearby vacancy defect that exhibits quantum-level sensitivity to magnetic fields.

This thing can work at room temperature, and each sensor is only a few micrometers in size; theoretically, it could even be inserted into a pinhole on the scalp.

However, upon closer examination, it was discovered that the advantage of this technology lies in its spatial resolution. A single nitrogen atom color center can be inserted into the tip of an atomic force microscope probe, allowing the resolution of magnetic domains at the 20-nanometer level when scanning the sample surface.

However, each nitrogen atom color center only receives one photon per optical readout, and the signal-to-noise ratio is locked by photon shot noise.

So he turned his attention to the newer OPM optically pumped magnetometer, which was only published in 2012.

Based on the Zeeman effect of atoms, when atoms such as rubidium, cesium, or helium are placed in a magnetic field, their energy levels will split, and the size of the split is proportional to the strength of the magnetic field.

Irradiating atomic gas with circularly polarized light causes the atomic magnetic moments to align in an orderly manner. Then, an radio frequency field is applied. When the radio frequency frequency matches the atomic transition frequency, resonance absorption occurs. The magnetic field strength can be calculated by measuring this frequency.

Michael Romalis' team at Princeton University has achieved a sensitivity of 0.16 femtotes per hertz in the laboratory. Moreover, by utilizing the Zeeman effect of alkaline metal vapor, it can operate at room temperature and is small enough to be woven into a soft hat and placed directly against the scalp.

This technology is still in the laboratory stage. Chen Yiran can only increase investment to accelerate its development.

Michael Romalis's team at Princeton University holds the record for sensitivity of optically pumped magnetometers.

John Kitching's team at the National Institute of Standards and Technology's Boulder Laboratory are pioneers in the miniaturization of optically pumped magnetometers.

Chen Yiran directly invested 300 million US dollars as joint research and development funding, enabling the two teams to jointly establish a new company.

The goal is to deliver the flexible helmet with optical pump magnetometer within 12 months.

Ultimately, it's just a matter of waiting. Chen Yiran feels like she's reading a novel and has reached a key point, but she's still quite far from the crucial moment that follows.

If I were to write something that happened six months later, I would feel a bit lost and could only settle down and live a peaceful life.

However, life also has many ups and downs. For example, Olsen's two older sisters would come to visit their younger sister all the time, which made Chen Yiran feel embarrassed to be affectionate with Dada when she came to visit.

On September 12, Chen Yiran, who had been staying at home for more than a month, finally left her house.

At the Yerba Buena Center for the Arts in San Francisco, another Apple event is about to begin.

This is the first iPhone since Steve Jobs' death, while the previous 4S was designed before Jobs' death. So this is also the first phone that Cook has independently led the development of.

As the current key figure at Apple, Chen Yiran will definitely come to support him.

Cook is a good leader in maintaining the status quo. Later, Apple's watch was also an innovation that spurred the development of the smart bracelet category.

Chen Yiran doesn't have that much time to spend on Apple, so she still hopes that Cook can run Apple the same way he did in his previous life.

Cook's performance was indeed very steady. His style on stage was somewhat deliberately modeled after Jobs, but he was more refined.

The iPhone 5 is indeed quite competitive. First of all, it is thinner and lighter than the 4S, measuring only 7.6 mm.

Although many people prefer glass back covers, the anodized aluminum back cover of the iPhone 5 also has a very good texture, and Chen Yiran actually really likes the design of the iPhone 5.

The A6 chip was also designed entirely in-house by Apple's chip team, resulting in excellent performance.

Chen Yiran also took the lead in optimizing some of the shortcomings that he had a lot of complaints about in his previous life.

First of all, there's the map. The current DuckMap is so much better than Apple Maps from before, it's completely comparable to Google Maps.

Secondly, after the interface was replaced, Chen Yiran quickly asked Apple to update the charging system, and had them customize thicker cables and power management chips.

Apple became the first phone to officially support fast charging, although it was only an increase from 0.5A to 1.5A, achieving a charging power of 7.5W based on 5V voltage, but it was at least a start.

After the press conference, Cook said to Chen Yiran backstage, "Next week, the Apple board will vote to formally address the Disney issue. Are you coming?"

"Never mind, I'll just participate by phone. It's just a formality anyway. Have Disney's independent financial advisor released their assessment?"

"They're all out now, just waiting for the handover of Lucasfilm."

"Okay, just keep an eye on things. I need to prepare for the collaboration with Oracle, and I have to attend their conference at the end of the month."
