This tracker does not use network remotes signal range 24 km

[Abstract]Drop Tag version sensor built-in low-power processor and power management system, support for receiving GPS signals, built-in six-axis sensor and sonar sensor, support for one-button alarm, and waterproof.

Tencent Digital (Mike) Everyone has a love of things, if the beloved things are lost, the first reaction must be like this.

Then the second reaction was "heartbreaking."

Even if you recall something that you lost, you can't help but sigh.

This feeling is like disappointment, powerlessness, but it is always difficult to extricate themselves. Then always tell yourself that the next time you must be careful and careful, don't lose anything.

However, if you want to not throw things away, you must rely on high technology to help you.

That's right, this is the Drop wireless tracker that we are introducing today. Drop uses Long-Range (LoRa) radio technology to create its own tracking network through Drop without the help of a mobile operator's network and monthly subscription fees.

Drop supports three functions: alarm, GPS positioning, and motion tracking. It also allows wireless charging and tag tag tracking via the cradle.

Drop's base supports LoRa protocol, and also includes Bluetooth connectivity, built-in 2000mAh capacity battery, wireless charging support, compatible with Moto Z, iPhone 6/6s/7 and Android system.

Among them, the Drop Tag version sensor has a built-in low-power processor and power management system that supports receiving GPS signals, built-in six-axis sensors and sonar sensors, one-button alarm, and waterproof.

The Drop's wireless charger can wirelessly charge the Drop Tag and Drop Base at the same time with 2W and 5W respectively.

Drop uses the LoRa peer-to-peer communication protocol and therefore requires less power than standard communication methods.

Drop uses an open connection area and the signal transmission distance can exceed 24 kilometers. If there are a large number of obstacles such as cities and forests, the effective distance can reach 8 kilometers.

At the same time, a plurality of Drops can also form a regional network, can be used as a connection tracker, and expand the effective range of tracking.

How about this, as long as the combination of Drop and smart phone, throwing things this kind of heartbreaking pain, it should not let you experience it again.

Currently, the Drop tracker has started crowdfunding on Indiegogo with a crowdfunding target of US$20,000. The early bird price is US$219 (about RMB1,500). If all goes well, it is expected to ship in September 2017. Interested friends may wish to rush to support it.

Fiber Optic Slip Ring

What is a fiber optic slip ring?


A fiber optic slip ring is a device that allows for the transfer of data, power, and signals between two rotating objects. The ring is made up of one or more optical fibers that are used to transmit light signals. These signals can be used to send power, data, or other signals between the two objects. The fiber optic slip ring is a newer technology that has many benefits over traditional slip rings.


How do fiber optic slip rings work?

A fiber optic slip ring is a device that allows electric current and optical signals to pass through a rotating joint. This is often used in applications where it is necessary to transfer data or power between two stationary points while the object rotates. The fiber optic slip ring uses light rather than metal to conduct these signals, which makes it ideal for use in high-speed or hazardous environments.


Types of fiber optic slip rings


When it comes to telecommunications, fiber optics are king. They're the backbone of almost every network today, and they're getting faster and more reliable all the time. That's thanks in part to a technology called fiber optic slip rings.


Advantages of fiber optic slip rings


A fiber optic slip ring is a device used in optical communication. It is a component of many fiber optic networks and it allows for the transmission of data over long distances without losing signal quality. Fiber optic slip rings are also used to improve the performance of other optical systems.


Disadvantages of fiber optic slip rings

Fiber optic slip rings are growing in popularity for rotating applications. Fiber optic slip rings provide many advantages over traditional electrical slip rings, including much smaller size, weight, and power consumption. However, fiber optic slip rings also have a few disadvantages. One disadvantage is that they can be more expensive than traditional electrical slip rings. Additionally, fiber optic cables are more fragile than electrical cables, so they can be more susceptible to damage.


Conclusion: What are the benefits and drawbacks of fiber optic slip rings?

When it comes to fiber optic slip rings, there are both benefits and drawbacks to consider. On the one hand, fiber optic slip rings offer a number of advantages over traditional metal contact slip rings. They are lighter in weight, which makes them easier to install and transport. They also generate less heat, making them safer to use in hazardous environments. Additionally, they provide superior performance in terms of electrical noise and signal integrity.


However, fiber optic slip rings also have some drawbacks. They are more expensive than traditional metal contact slip rings, and they can be more difficult to repair if they malfunction. Additionally, they may not be suitable for some applications due to their limited range of motion.
