A report by investment data analysis company Tracxn pointed out that startups in the virtual reality sector have raised $533 million this year. In addition, 153 investments in startups occurred in 2015, totaling $690 million. YiVian found from the report that investment in VR start-ups increased significantly by 277 percent in 2015, from $ 183 million in 2014 to $ 690 million.
Most of the investment comes from the early stages, followed by the late stage. Early funding was $400 million in 2016, and late funding was $85 million, while seed round investment was only $46 million.
Among them, the B-round investment in the early stage was the highest, reaching 31.8 million US dollars.
In 2016, the largest investment came from the Hinduja Group, which invested $100 million in startups in MindMaze in February. In addition, the startup NextVR completed $80 million in financing in August, led by Netease and CITIC Guoan.
The most active investor in the VR space is Rothenberg Ventures, who have invested in startups such as JauntVR and Matterport. Boost VC, Techstarts, Intel Capital and Qualcomm Ventures are also very active.
Samsung, the electronics giant, has been paying close attention to this area. Samsung Ventures has invested in seven startups, including Wevr, Replay Technologies, Bubl and FOVE.
On the other hand, Intel is more inclined to acquire rather than invest. In September, Intel acquired Movidius, a mobile video processor chip company, for a total of $86.5 million. In addition, Intel acquired Replay Technologies for $175 million in March this year.
Snapchat also acquired two VR startups, Obvious Engineering and Seene, but did not disclose the specific amount. Apple also acquired Faceshift in November this year, and did not disclose the specific amount.
Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
