ByteDance
ByteDance Ltd. () is a Chinese internet technology company headquartered in Beijing and incorporated in the Cayman Islands. Founded by Zhang Yiming, Liang Rubo and a team of others in 2012, ByteDance developed the video-sharing social networking services and apps TikTok and Chinese-specific counterpart Douyin. The company is also the developer of the news platform Toutiao. As of June 2021, ByteDance hosts 1.9 billion monthly active users across all of its platforms. ByteDance has attracted legislative, regulatory, and media attention in several countries over surveillance, privacy, and censorship concerns.

Wi-Fi 6
IEEE 802.11ax, officially marketed by the Wi-Fi Alliance as (2.4 GHz and 5 GHz) and (6 GHz), is an IEEE standard for wireless local-area networks (WLANs) and the successor of 802.11ac. It is also known as ''High Efficiency'' , for the overall improvements to clients under dense environments. It is designed to operate in license-exempt bands between 1 and 7.125 GHz, including the 2.4 and 5 GHz bands already in common use as well as the much wider 6 GHz band (5.925–7.125 GHz in the US). The main goal of this standard is enhancing throughput-per-area in high-density scenarios, such as corporate offices, shopping malls and dense residential apartments. While the nominal data rate improvement against 802.11ac is only 37%, the overall throughput increase (over an entire network) is 300% (hence ''High Efficiency''). This also translates to 75% lower latency. The quadrupling of overall throughput is made possible by a higher spectral efficiency. ...

Virtual Reality Headsets
A virtual reality headset (or VR headset) is a head-mounted device that provides virtual reality for the wearer. VR headsets are widely used with VR video games but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display (providing separate images for each eye), stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the user's head to match the orientation of the virtual camera with the user's eye positions in the real world. Some VR headsets also have eye-tracking sensors and gaming controllers. The VR glasses use a technology called head-tracking, which changes the field of vision as a person turns their head. The technology may not be perfect, as there is latency if the head moves too fast. Still, it does offer an immersive experience. History The Sega VR, announced in 1991 and seen in early 1993 at the Winter CES, was never released for consoles, but was utilized for ...

Pancake Lens
A pancake lens is colloquial term for a flat, thin camera lens assembly (short barrel). The majority are a prime lens of normal or slightly wider angle of view. Some are zoom lenses. Motivation Pancake lenses are primarily valued for providing quality optics in a compact package. The resulting camera and lens assembly may even be small enough to be pocketable, a design feature which is usually impractical with conventional SLR bodies and lens assemblies. Pancake lenses can be very short and flat because they do not need large amounts of optical correction, i.e. extra lens elements. The problem arises when such lenses have too short a focal length to fit in front of the retractable mirrors used in reflex cameras. In such a situation, a pancake lens focuses in front of, rather than on, the focal plane (film or light sensor) of the camera. This has necessitated the design of retrofocus lenses that refocus the image farther back, which is why such lenses are longer and bulkier ...

Meta Quest 2
Meta Quest 2 (initially sold as Oculus Quest 2) is a virtual reality (VR) headset developed by Meta Platforms (formerly Facebook, Inc.). It was unveiled on September 16, 2020 and released on October 13. As with its predecessor, the Oculus Quest, the Quest 2 can run as either a standalone headset with an internal, Android-based operating system, or with Oculus Rift-compatible VR software running on a desktop computer. It is a refresh of the original Oculus Quest with a similar design, but with a lighter weight, updated internal specifications, a display with a higher refresh rate and per-eye resolution, and updated Oculus Touch controllers with improved battery life. The Quest 2 received mostly positive reviews as an incremental update to the Quest, but some of its changes faced criticism, including its strap, reduced interpupillary distance (IPD) options, and a new requirement for users to log in with a Facebook account to use the headset and Oculus services.

Lithium-ion Battery
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluetooth 5
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet Blue ...
