Chinese smartphone giant Xiaomi has sued US government officials, including Janet Yellen, over its inclusion on a Pentagon investment blacklist
Chinese smartphone maker Xiaomi has sued the US government over its inclusion on an investment blacklist. It filed a lawsuit Friday against several US government departments and officials. Xiaomi denied being controlled by Beijing, and said the investing ban would cause "irreparable harm." Visit Business Insider's homepage for more stories. Chinese smartphone giant Xiaomi has sued the US government over President Donald Trump's decision to add it to a blacklist that would block American investment.
With the "Mi Air Charge", Xiaomi today introduced wireless charging technology that works without having to hang up the devices. Similar to data, the charge is transmitted wirelessly.
Wireless charging using a charger that is only in the room but does not require the devices to be placed on the charger would be a technological breakthrough. Because it could make the charging process completely seamless.science fiction: wireless electricity charges devices everywhere in the room
devices would be supplied with fresh energy while the users could continue to use it. Loading would no longer be a process that users would have to actively take care of in any way.
After sanctions: Xiaomi is suing the USA
Together with other Chinese companies, Xiaomi is on a blacklist for US investors. Xiaomi has filed a lawsuit against this. © Robson90 / Shutterstock Xiaomi is currently on a blacklist in the USA. After the US Department of Defense blacklisted Xiaomi and eight other Chinese companies in mid-January, Xiaomi is suing this measure. The Chinese smartphone provider rejects the US government's allegations.
has been researching and developing such solutions for years. At first, the US company Energous had already received approval from the regulatory authority FTCcharging technology. That was back in 2017. Devices that use the technology will not yet exist in 2021 either.
So a certain skepticism is appropriate when Xiaomi introduces wireless and contactless charging via "Mi Air Charge" today. As the company confirmed to, there won't be any commercial products that can use the technology this year. There is also no schedule for the availability of the “Mi Air Charge”.

The system sounds exciting., Xiaomi describes the cornerstones of the technology: Accordingly, the core technology of remote charging consists in the spatial location of devices to be charged with subsequent energy transfer. To this end, Xiaomi's self-developed charging station has installed five phase interference antennas, which should be able to determine the exact location of the smartphone to be charged. Once the device is located, a phase control array consisting of 144 antennas transmits millimeter-wide waves directly to the smartphone.
How electric cars may change the future of the Australian service station
Experts predict a shift away from hydrocarbon fuels in the decades to come. Does that mean saying goodbye to the service station as we know it?From refuelling the car to buying an ice cream on a hot day or picking up supplies on a road trip — it has been a hallmark of most Australian lives.
The smartphone or another device to be charged - Xiaomi imagines- must also be equipped with a set of antennas. This set consists of an antenna array that is able to send position information to the charger and another array that can receive the sent charging pulses. This converts the bundled waves into electrical energy via a rectifier and charges the battery in this way.
According to Xiaomi, devices can be charged with a charging power of up to five kilowatts in this way. The "Mi Air Charge" should be able to serve several customers at the same time. Visible obstacles such as cupboards or seating should not impair the charging process.
Xiaomi has not revealed when the system will go on sale. Compared to Energous' Wattup system, Xiaomi has a massive advantage: It has devices into which it could build the charging technology, while Energous would have to convince manufacturers to use their system.
Free electric vehicle charging switched on
Drivers can recharge their electric vehicles for free in regional Victoria after the first of a national network of no-fee charging stations were switched on.Motorists can plug-in at the townships of Nhill and Rainbow in Victoria's west, with another 98 free chargers set to be rolled out across the nation by mid-2021.
Motorola also presents wireless charger
The “Motorola One Hyper” system, which the manufacturer also teased on the Chinese Twitter alternative Weibo today, seems to be at an experimental stage of development. This is what thereport.
The Hyper should also be able to charge devices without contact via radio. The manufacturer has not communicated any details on the technical design. After all, the charger should bridge a distance of up to one meter in the air and charge two devices at the same time.
Unlike the Xiaomi system, obstacles between the charging station and the device cause the charging process to stop. In any case, this is the case as far as the obstacles are body parts. This should also suggest potential health risks.
