Over the past few years, the market for smart wearables has been growing at a rapid pace. Chinese conglomerate, Xiaomi was one of the first companies to encash on the booming industry. The company launched its first activity tracker, the Mi Band in the year 2014 which was warmly welcomed by the consumers. After the success of the aforementioned device, the company launched two more fitness bands, the Mi Band 2 and the Mi Band 3 in the year 2016 and 2018 respectively. For quite some time, the company has been rumoured to launch yet another fitness band in the form of Mi Band 4. The former was previously certified on the mandatory Bluetooth SIG website which strengthened the claims of its presence.
The existence of the Mi Band 4 is now verified accrediting to its NCC Taiwan certification. The listing is sufficiently detailed to reveal the looks the features of the upcoming fitness band. Notably, in terms of looks, the device is not significantly different than its predecessor. However, the innards of the Mi Band 4 seem worthy of attention.
The fitness tracker looks like an elongated capsule with plastic on the front and bottom. The top of the device accommodates a small display and control button while its rear is occupied by charging pins and a heart rate sensor. The cross section of the Mi Band 4 exhibits the heart rate sensor in all its glory which is an appreciable feature considering it will be aggressively priced.

In terms of features, the Mi Band 4 will support Bluetooth 5.0 LE (Low Energy) which is assumed to provide a longer battery backup. Furthermore, the images also reveal the support for NFC connectivity. Though, reports claim that this feature will only be limited to the Chinese variant of the fitness tracker. All in all, the Mi Band 4 seems to be a worthy upgrade which going by the number of leaks and certifications will launch soon.
The design of the 3D printed microscope is based on digital holographic microscopy. Bahram claims that the images produced by the portable microscope are almost twice the resolution of the images produced by traditional microscopy. The applications of such a device are not limited to research and medical science, rather, it can be used in defence and education as well. Since the entire microscope is manufactured out of 3D printed parts, it can be assembled anywhere and with relative ease. Moreover, unlike other scientific equipment, the 3D printed microscope is not expensive at all. Also, the incorporation of alternative components such as image sensors could drastically reduce the price point of the microscope when/if it is mass produced at some point. 
The core of the new microscope works in similar ways to a traditional digital holographic ones, where a digital camera captures the hologram generated when the light coming from the sample object interferes or colludes with the reference light wave. This process relies on a controlled setup where the environment has to be free of vibrations and temperature fluctuations. Instead, the newly manufactured equipment combines the two images using a super-resolution technique, which is scientifically referred to as Structured Illumination Microscopy. In this process, a structured light pattern is created with the help of a clear disc.

The laptop features a 15.6 inch Full HD IPS display with 300 nits of brightness. It runs on the 8th Gen Intel Core i7 (i7-8565U) processor, which is bundled with up to 12GB of RAM and up to 512GB PCIe SSD for storage. As mentioned previously, the Ideapad S540 features NVIDIA’s latest mobile graphics chip, the GTX 1650. It is based on the Turing architecture, which provides higher performance than its predecessors while consuming lesser power.
As per reports, the performance levels of the GTX 1650 are almost 70 percent better than the GeForce GTX 1050 graphics card. The 4GB GDDR5 GPU chip features a total of 896 CUDA cores with a base clock speed of 1485 MHz and a turbo boost up to 1665 MHz. It does not require it’s separate power source, instead, it consumes power from the 75W power input from the PCIe bus. The company claims that the laptop provides a power backup of up to 12 hours. The Lenovo Ideapad S540 weighs at 1.8 kilograms.

The Japanese manufacturer previously revealed information regarding some features of the upcoming console. For instance, the PlayStation 5 is expected to sport 3D audio technology, which will enable gamers to have an immersive gaming experience. Another speculated feature of the PS5 is the incorporation of a Solid State Drive or an SSD. This will lead to visibly faster game load times and seamless switching between various applications within the console’s interface. 
The Sony PlayStation 5 is expected to be the first console to sport 8K resolution gaming. Of course, to take full advantage of the same, gamers will need to plug in their console to an 8K supported panel, but Sony making a move for future-proof gaming will surely be appreciated. Last but not the least, some new PS5 games may support Ray Tracing. Ray Tracing simulates the interaction of real world light with real time objects in the game, which leads to lifelike graphic rendering. Battlefield 5 was the first game to support Ray Tracing on NIVIDA RTX powered PCs, and we can expect developers to release more titles in accordance with Ray Tracing technology if consoles start supporting it too.

First leaked on April 24 by a Dutch website, the roadmap highlights Intel’s key plans over the next two years. As per the roadmap, the company will launch a whole new refreshed lineup of Coffee Lake CPUs in the latter half of 2019. Intel will then follow up the Coffee Lake processors with the Comet Lake series of processors in the early half of the year 2020. Since Intel often labels its desktop processors as the “S-series”, it’s clearly visible in the roadmap that Intel will keep working on 14-nm S-series processors until 2022. 
Another highlighting fact is that the company has marked its upcoming 10nm “Tiger Lake” processors as TBD, or To Be Decided. Tiger Lake architecture-based CPUs will be released as the “U-series”, and they will be specifically targeted towards mobile devices such as laptops. Planned for release somewhere in the second quarter of the year 2021, the TBD label on the aforementioned CPUs may mean that the company might have different plans for them.
