Recently, a member of the Federal Communications Commission (FCC) recommended that the committee should specifically open the 50-60 GHz band for virtual reality (VR) to meet the needs of VR in transmitting high-resolution images. However, as the low frequency band becomes more and more crowded, future wireless communication will develop in the field of high frequency and ultra high frequency, or an inevitable trend. Whether the virtual reality application can successfully obtain the exclusive frequency band at 50~60GHz, I am afraid there are still many variables. According to the RadioMagOnline website, FCC Commissioner Ajit Pai suggested on the C-SPAN program of the US cable channel that the FCC should consider opening up the 50~60GHz high spectrum for VR to meet the huge bandwidth requirements that may arise. Pai pointed out that because high-resolution virtual reality images are extremely hungry for bandwidth requirements, it is necessary to occupy a large number of frequency bands to meet their application needs. As for being asked about the role of the FCC in the development of VR technology, he quoted the idea of ​​a representative of the CES exhibitor that the industry really hopes that the FCC can assist. The industry hopes that FCC can help plan a wide range of channels for virtual reality applications, and this is indeed a place where FCC can help. However, the 50-60 GHz band is currently a virgin land that has not yet been developed, but many industry groups and standards organizations have been eyeing this band. For example, the 5G communication standard, which is expected to be officially released in 2020, is still under development. However, Korean, Japanese, and US-based companies have a keen interest in developing technologies above 6 GHz. South Korea has even expanded its 5G spectrum plan. To the 50.4~52.6GHz and 66~74GHz bands. As the forces of all parties want to develop towards the ultra-high frequency band, whether the virtual reality related industry can obtain the dedicated 50~60GHz frequency band as expected, there still seems to be many variables.

Capsule Slip Ring

What is a Capsule Slip Ring?

Capsule slip rings are a type of electrical connector that are used to transfer power and data between two rotating objects. They are commonly used in applications where there is a need to send or receive signals from a stationary object to a rotating one, or vice versa.


How Does it Work?

Capsule slip rings work by using a series of electrical contacts that rotate with the object on which they are mounted. These contacts are spaced evenly around the circumference of the ring, and as they rotate they make and break contact with corresponding contacts on the other object. This allows power and data to be transferred between the two objects without any interruption.


Advantages of Capsule Slip Rings

There are several advantages to using capsule slip rings in place of other types of electrical connectors.


For example, the rotation of the contacts causes them to be freely accessible and therefore free from dust and debris. This makes them ideal for applications where connector maintenance is often a problem.


Because the contacts are freely accessible, they can be readily replaced if a fault occurs. They also have very low electrical resistance, making them ideal for transmitting radio frequency signals. Because of the low resistance, this type of connector is often used in high-speed data transmissions.


This type of Conductive Slip Ring is similar to the shape of a hat. The brim part is a flange with a conductive slip ring. The function of the flange is to facilitate installation. It is connected to electrical equipment through the fixing hole of the flange. It can be firmly installed on the equipment. Therefore, the stator of the cap-type slip ring is generally fixed by the outer layer with a flange, and the inner part is the rotor with the inner shaft rotating. The stator and the rotor are not fixed, and the details will be different according to the installation method.
