In recent years, with the advancement of technology, wearable electronic devices have gradually been favored by more and more users. The three giants of the mobile phone industry, Huawei Samsung Apple, have released a variety of smart watches. Recently, there is a very unique smart watch that attracts my attention. Not only does it have an Android built-in system, but it also comes with a 360-degree rotating camera, which is practical and full. Previously, this watch attracted wide attention during crowdfunding abroad. Now, this watch will be registered on the domestic crowdfunding platform Jingdong Crowdfunding on April 24. In some special agent movies, you can often see some cool things, shoes that can be called, cars that can launch missiles, and of course multi-function watches. Agents often use watches for special shooting, which is also envied by many people, although some manufacturers have introduced a camera with a camera, but because of the poor adjustment of the shooting angle, the need for a variety of curved wrists, many people have given up this experience . Introducing the ARROW 360 smart watch today, it is equipped with a rotatable camera that can easily adjust the shooting angle. This design allows the watch to take pictures to meet the needs of photography in most situations. Not only that, ARROW 360's camera bezel also has a directional microphone, shooting video is also hand-to-hand, and also has anti-shake function. Completely solved the pain point above, making you cool to no friends. When you see a beautiful view, press the camera button on the right side of the watch to enter the camera directly. After entering, press the button again to complete the shooting, eliminating the cumbersome steps of taking out the phone and turning the camera on. The beautiful moments are always fleeting, and this ARROW 360 can help you record the moment well. The 1080P HD camera also guarantees the image quality. After the shooting is finished, the watch can be previewed in real time, and the watch also comes with a photo editing function, which can not only perform cropping and rotating operations on the watch, but also add filters. Even more powerful is the ability to send directly to mobile phones via Bluetooth and to social networking sites. In the self-timer, the ARROW 360's 360-degree rotatable design plays a big role. Turning the dial directly can turn the camera to the self-timer direction. At this time, the watch will automatically enter the self-timer mode, and the good moment will be recorded. This feature is perfect for outdoor play. As an excellent smart watch, ARROW 360's highlight function is far more than just taking pictures. In configuration, ARROW 360 is equipped with MTK6580 quad-core processor and 1+8GB memory configuration. The powerful processor ensures the smooth running of the system. 1G running memory guarantees the fluency of multi-tasking, 8GB of large memory can also let you take pictures as you like, equipped with 480mAh battery, can continue to shoot for two hours. It can also be seen from this that this is a sincere product. For outdoor enthusiasts, this watch is a perfect partner. It is very difficult to use mobile phones in hiking, cycling, and other sports, but if you want to record these moments, this ARROW 360 is a very good choice. For example, for many cycling enthusiasts, it is often necessary to wear various protective gears during riding, including gloves. When you see a beautiful scenery, you must first take out the mobile phone, then take off your gloves and then shoot. The process is more cumbersome and it is easy to miss the beautiful scenery. With this watch, you can directly raise your hand and press the button twice to complete the shooting. It not only helps you capture the beautiful moments, but also makes you more convenient in the usual shooting process. In daily use, this watch also supports notification reminders, weather forecasts, call reminders, text messages and other functions. It is reported that this watch was originally created by a group of young people in Canada. They are very passionate about outdoor sports. They are familiar with the pain points of outdoor sports enthusiasts. They have been conceived since 2014, and then designed, patented, developed, and finally in 2017. Indiegogo crowdfunding was launched in the month, winning the support of many users and raising $520,000. This project has also attracted the attention of Google, and it has been used in Android wear, which has aroused widespread concern.
Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
1. SCSI can support multiple devices, SCSI-2 (fastscsi) can connect up to 7 SCSI devices, and widescsi-2 can connect 15 SCSI devices. In other words, all devices only need to occupy one IRQ. At the same time, SCSI also supports a wide range of devices, such as CD-ROM, DVD, CDR, hard disk, tape drive, scanner, etc. SCSI-180°DIP Section ShenZhen Antenk Electronics Co,Ltd , https://www.antenkwire.com
2. SCSI also allows one device to transfer data and another device to look up its data. This can achieve higher performance in multitasking operating systems such as Linux and windows NT.
3. SCSI occupies a very low CPU, so it has obvious advantages in multitask system. Since the SCSI card itself has a CPU, it can handle all the transactions of SCSI devices. When the host CPU sends work instructions to the SCSI card, the SCSI card will work by itself. After the work is finished, the work results will be returned to the CPU. In the whole process, the CPU can carry out its own work.
4. The SCSI device is also intelligent. The SCSI card can queue CPU instructions by itself, which improves the work efficiency. In multitasking, the hard disk will be in the current head position, and the adjacent tasks will be completed first and then processed one by one.
5. The fastest SCSI bus has a bandwidth of 160MB / s, which requires the use of a 64 bit 66MHz PCI slot. Therefore, the maximum speed that can be achieved in the PCI-X bus standard is 80mb / s. if it is used with a dedicated hard disk with 10000rpm or 15000rpm, it will bring obvious performance improvement.
