Virtual reality technology (VR) mainly includes simulation environment, perception, natural skills and sensing equipment. The simulation environment is a computer-generated, real-time, dynamic, three-dimensional, realistic image. Perception means that the ideal VR should have the perception that everyone has. In addition to the visual perception generated by computer graphics technology, there are also perceptions such as hearing, touch, force, and motion, and even olfactory and taste, also known as multi-perception.
Natural skills refer to the rotation of the person's head, eyes, gestures, or other human behaviors. The computer processes the data that is appropriate to the actions of the participants, responds to the user's input in real time, and feeds back to the user's facial features. . A sensing device is a three-dimensional interactive device. Let's take a look at the 2016 Enthusiasts.
Recently, VR fire can't work, there is a kind of meaning that you don't know that VR is embarrassed to go out and chat with others. However, there are still many people who read a lot of articles, that is, they don't know what VR is. What is the difference between VR and AR? It is even more difficult for MR and CR. Today, we will answer these questions for you.
VitualReality, virtual reality, is the use of computing equipment to simulate the creation of a three-dimensional virtual world, providing users with simulations of visual, auditory and other senses, with full "immersion" and "presence". As the saying goes, everything you see is computer-generated and fake. Typical output devices are the Oculus Rift, HTC Vive, and more.

According to foreign media reports, Oculus has recently updated and upgraded the "Platform Integrity Check" program. This will mean that HTC Vive users can no longer use Revive to experience Oculus content, because the upgraded system will directly check whether the hardware is the Oculus Rift platform. If it is not Oculus Rift, the system will refuse to run the corresponding content.
In this regard, Oculus said that the update does not target HTC Vive, just to prevent pirated helmets. This statement can give full marks, but considering that the number of users who purchase VR devices is still a minority, this "closed" approach seems to be difficult to get the hearts of the people.

Closed impellers have a back and front wall around the vanes, to increase strength. Closed impellers are used primarily in larger pumps and can be used in applications that handle suspended-solid service.
These types of impellers are commonly found in clear liquid applications. They don't do well with solids and are difficult to clean if they become clogged.
Still not sure which impeller will be best for your next pumping application? Be sure to check wtih an application engineer who is well versed in pumps and selection best practices.
