Vienna has created a transistor that can replace several transistors

Published

on

Researchers at the Vienna University of Technology have developed an “adaptive” transistor. Unlike the transistors used in digital logic circuits now and capable of receiving, depending on the control signal, two states corresponding to “one” and “zero”, the function of the adaptive transistor can be “programmed”.

The structure of the new transistor includes two electrodes that are connected by a very thin germanium element. Above the germanium element is a gate similar to those used in conventional transistors. The decisive factor is the presence of an additional control electrode, which is located at the interface between germanium and metal. It is he who allows you to dynamically program the function of the transistor.

The fact is that germanium behaves in a special way: if a voltage is applied, the current initially increases, but after a certain threshold value it decreases again – this is called negative differential resistance. The control electrode can be used to change the threshold value.

The new transistors are not intended to completely replace traditional transistors. They should be viewed as complementary, much like FPGAs to processors.

Scientists argue that in some circuits this will allow the use of significantly fewer transistors, which will have a positive impact on power consumption and performance. For example, a 160-transistor circuit that performs arithmetic operations can now be built with only 24 transistors. The researchers hope that in the long term it will be possible to get to the point where transistors can adapt on their own as needed, provided AI is developed that can take advantage of their benefits.

Mini PC for those who want to stand out Chatreey

On Aliexpress, an unusual type of mini-PC with a fairly powerful processor appeared on sale. The Chatreey AMR5 model is based on the Ryzen 5 5600U, which offers six cores and a Vega 7 GPU.

The barebone kit is priced at $415, but you can also buy a PC preloaded with 8GB to 64GB of RAM and a 512GB to 2TB SSD. The top version will cost about $1,150.

The novelty stands out, of course, primarily for its design. Moreover, this very design is still associated with one of the functions of the PC. The ring at the top serves as a mode switch. It appears to toggle Windows power modes: Silent, Balance, and Performance Mode.

You can also note support for Wi-Fi 6, backlight, HDMI, DisplayPort, USB-C, USB 3.0 (x4), RJ45 ports and dimensions of 156 x 133 x 71.8 mm.

Amazon has quietly updated its budget Fire 7 tablets. To be more precise, the Fire 7 and Fire 7 Kids have been updated.

There are no cardinal changes – these are all the same ultra-affordable devices with the appropriate parameters. Since technically the novelties are almost identical, we will talk about them as a single product.

So, the tablet still has a seven-inch screen with a resolution of only 1024 x 600 pixels. This is a very low resolution for 2022, but the price of the tablet is only $60 ($110 for the Kids version).

It is based on an unnamed 2 GHz quad-core processor, which is 30% faster than the solution in the previous generation of the tablet. RAM has doubled, but it’s only 2 GB. Flash memory is available 16 or 32 GB, since there is a slot for microSD. Also autonomy increased by 40%, and now Amazon promises up to 10 hours of work. From the rest, we can note the appeared USB-C port, a 2 megapixel camera and three colors.

Apple AirPods Pro ruptured a 12-year-old boy’s eardrums, leaving him disabled. The company was sued

Apple AirPods Pro ruptured a 12 year old boys eardrums leaving him

Apple is facing legal action over AirPods.

According to sources, the company was sued due to the fact that a 12-year-old child was injured due to the use of Apple headphones. One would think that the headphones exploded, as this sometimes happens, but in this case the reason is completely different.

The child was watching a movie on Netflix using an iPhone and AirPods Pro. At some point, the Amber Alert system (child abduction alert system) went off. Initially, the headphones worked at a low volume, but the sound of Amber Alert was so loud that it ruptured the child’s eardrums and damaged the cochlea. After the incident, the boy suffered from hearing loss, nausea, dizziness and tinnitus. He is now required to wear a hearing aid.

In fact, this happened back in 2020, but, as is often the case, the general public will learn about such incidents much later.

The lawsuit alleges that Apple is aware of “defective” AirPods that do not mute Amber Alerts. What’s more, Apple also didn’t include a warning about a potential issue that users might encounter.

The lawsuit against Apple seeks damages for the boy and his parents, who are under enormous emotional stress due to the situation. The lawsuit seeks “punitive damages in an amount that will punish defendants for their conduct and deter other technology companies from engaging in such misconduct in the future.”
