Facebook about to launch smartwatch?. Illustration The Verge said that Facebook’s smartwatch will have a removable screen, equipped with up to 2 cameras to help take photos and videos without the need for a smartphone. In addition, you can also share photos directly from the smartwatch to Facebook or Instagram easily. A camera of the smartwatch will be mounted on the front to help make video calls and a camera placed on the back of the screen with 1080p resolution with integrated autofocus. Facebook’s idea is to encourage the use of smartwatches to completely replace current smartphones. A plan by Mark Zuckerberg, to be able to surpass Apple and Google, when unable to compete in the smartphone market. Currently, Facebook has also worked with major carriers in the US to support LTE connectivity for its smartphones. That means users can use Facebook’s smartwatch to replace smartphones. Facebook expects to hit around six figures in revenue in its first year. And their products will be distributed through the network’s retail chains. According to the plan, Facebook’s smartwatch will be launched in 2022 and it will use Google’s operating system.

Smartwatch is part of Facebook’s plan to compete with Apple and Google in the hardware market. The device also creates an opportunity for Facebook to confront Apple in the context of the not-so-good relationship between the two companies. Facebook is said to be developing the first smartwatch model. Illustration: The Verge. The conflict between Facebook and Apple stems from the privacy monitoring feature on iOS 14.5. While Apple takes a strong stance on privacy, requiring companies like Facebook to consult before tracking users, the social network argues that it affects advertising revenue, which is “chicken”. lay golden eggs” for the company. The smartwatch development information comes after Facebook faced many privacy-related scandals. According to the The Verge , they could make it difficult for Facebook to convince users to buy this smartwatch, especially when the product is also focused on health monitoring and heart rate monitoring. Many fear that information about health and heart rate could help Facebook better know each user, after the company’s services have collected too much data. An unnamed source said Facebook is also approaching companies that make accessories, helping to attach cameras to many items such as backpacks. Facebook may also work with some carriers in the US to integrate LTE connectivity, allowing the smartwatch to work independently without needing to be connected to a smartphone. Privacy is a concern on Facebook’s smartwatch. Photo: The Tech Lap. Facebook is said to launch the first smartwatch model in the summer of 2022 for $ 400, equivalent to Apple Watch Series 6. Expected sales for the device are several hundred thousand, lower than the 34 million Apple Watch units sold. sold out last year, according to Counterpoint Research . This is not the first time Facebook has launched a hardware product. In 2013, Facebook’s Android smartphone in cooperation with HTC failed miserably, while sales of the Oculus virtual reality headset and Portal smart display were not disclosed. However, a Facebook official said that sales of the Oculus Quest 2 are higher than all of the previous Oculus VR headsets combined. In 2019, Facebook considered buying Fitbit wearables before Google successfully negotiated. Facebook spent about $1 billion, devoting hundreds of employees to developing its first smartwatch. However, even with the camera and unique features, it is unlikely that this company’s device will be as well received as the Apple Watch. ‘I don’t want to be tracked by Facebook’ The iOS 14.5 update allows users to block Facebook from tracking their data. Therefore, advertising on this platform gradually becomes less effective.

It took about 4 years for Huawei to launch the new Watch 3 generation, so it is not difficult to understand that this product is significantly different from the design of its predecessor Huawei Watch 2.

With modern air defense systems, dealing with such UAVs is both extremely difficult and very expensive. REX-1 electromagnetic gun. (Source: Top War) To deal with small pulse and reconnaissance UAVs, Russia is developing specialized equipment such as the Kalashnikov Military Technical Corporation’s REX-series electric guns or special anti-air missiles being developed by engineers of the Russian Nuclear Center. In 2015, Kalashnikov Military Engineering Corporation acquired a stake in drone maker ZALA Aero to develop unmanned technology and anti-UAV weapons. This group is working to develop electronic warfare systems focusing on fighting against modern UAVs. Among them are two models of non-lethal weapons REX-1 and REX-2 that appeared at military technical exhibitions. REX-1 electromagnetic gun In terms of parameters and weight, the REX-1 electromagnetic gun is compact in size, comparable to modern automatic weapons. According to the manufacturer, the weight of REX-1 reaches 4.5 kg, built-in battery backup, ensures 3 hours operation. The main mission of the REX-1 is to protect critical facilities and enclosed areas from intrusive drone vehicles. This is especially important because modern air defense systems are not always guaranteed to destroy UAVs, and detecting small drones using conventional electronic reconnaissance means is difficult. towel. According to the Kalashnikov Group, REX-1 can interfere with the signals of the US GPS satellite navigation system, the BeiDou of China, the European Galileo or the Russian GLONASS within a radius of 5 km. In addition, at a distance of 1 km, REX-1 can block LTE, 3G, GSM signals, interfering with the running frequencies: 900 Mhz, 2.4 GHz, 5.2-5.8 GHz. Thanks to these capabilities, the REX-1 is able to neutralize enemy drones without causing physical harm. Besides, controlling the REX-1 is quite simple. In addition, the REX-1 is equipped with additional lights, target indicators and various points of view. REX-2 electromagnetic gun In the framework of the Army International Forum 2019, the new version REX-2 launched has been rated by many military experts as the world’s most compact anti-drone gun. The main advantage of the REX-2 is its compact size and light weight. If the original design REX-1 weighed approximately 4.2-4.5 kg, the weight of the non-lethal REX-2 was only about 3 kg and the length should not exceed 500mm. According to the developers, the REX-2 is designed to disable all types of UAVs, including optical devices used on the ground or underwater. The lighter and smaller version of this device effectively overwhelms the signal of the satellite navigation systems within a radius of 2km. The REX-2 works by suppressing radio and satellite navigation signals – technology used in the operation of most modern UAVs. The REX-2 developer wants this new weapon to be able to counter a wide variety of targets since their components are interchangeable, as well as tailored to suit missions. Specifically. Antidrone jet rockets Last March, the sheet Izvestia reported that the experts of the Russian Federal Nuclear Center are developing high-speed anti-drone equipment with jet missiles (antidrone). The antidrone missile consists of the missile hull, a target guidance system and a net-trap container (nets with dumbbells in corners). Missiles carrying “mesh bullets” shoot directly to the enemy’s drones, then open the net, ensuring to capture and disable the UAV. However, experts say, similar UAV trap projects in Russia are not effective enough to intercept high-speed vehicles when performing complex aerial maneuvers. According to the news agency RIA Novosti In order to intercept UAVs with mesh bullets, the antidrone missiles need to be adjusted to launch a network of traps at a predetermined rate. The process above will take steps and be difficult as high-speed targets can quickly get out of range of the device. (According to Top War)
