Going Direct: The Future of LTE

Could we see a future free from unsightly cell phone towers? A number of companies are working hard on technology that will let smartphones communicate directly with other devices, provided they’re within a 500 meter range. These will use LTE radio frequencies to connect, bypassing cell phone towers to talk with other mobile devices, local businesses, and other devices within this range. This new wireless technology is called LTE Direct, and it could become a common feature in the near future.

A Broader Range

With a range spanning up to 500 meters, LTE Direct is an exciting prospect because it can reach farther than either Bluetooth or Wi-Fi. Big-name companies including Facebook, Yahoo, and Qualcomm are currently experimenting with it, and we could see LTE Direct enabled devices later this year. So what would the benefits be of this type of technology, and will it become a widespread future of our LTE phones?

Multiple Benefits

One benefit of LTE Direct could be its ability to automatically connect with nearby businesses, landmarks, and people. This would be useful when you’re travelling and want to find a certain type of business, or if you’re looking for specific information on a local level. From the business standpoint, this would provide companies with new opportunities for targeting their customers.

Another benefit of this technology is its ability to connect with other devices without draining its power. IT would be able to discover phones and beacons in public transportation networks or businesses while using very little power, compared to alternative technologies such as Bluetooth. It would constantly be scanning your environment, looking for these connections. Beacons would be particularly useful for commuters and tourists, in need of special information about train delays or weather reports.

On a social level, the technology could also have a number of new and exciting uses. It’s easy to see why Facebook is interested in this technology when you think about how it could be used to broadcast information about local meet-ups and special events. A band could play a surprise gig, broadcasting details with little notice to fans in the area, for example. Community groups could LTE Direct to organize impromptu meetings.

From a technological standpoint, LTE Direct could help reduce network traffic as well. In major cities or during busy events, a high volume of people often try to connect to a single cell tower, which reduces network speeds and leads to glitches. LTE Direct would effectively eliminate this traffic, because the devices would simply communicate with one another to glean information rather than clogging the network.

The Bottom Line

LTE networks are already considered to be the future of connectivity. At the moment, there are two configurations, including FDD and TD LTE configuration with Nokia Networks and other 4G providers. It’s not a huge leap to think about how these could be combined with the LTE Direct technology that’s currently in development. These are just a few ways that LTE Direct could lead to a more immersive mobile experience, creating new apps that route data between devices and make it easier to receive user-targeted information when and where you want it.

The Night Vision Technology Evolution


Camera companies have long been deep in research trying to find the perfect formula to get quality photos and video in low light. the night vision technology evolutionThough night vision is not a new idea, it’s constantly being altered and further developed.

Night vision evolved from military technology developed in the late 1940s.

It combines several methods for better images to allow a person to see in absolute darkness. So what are these methods?

How Does it Work?

The first method: gather light that is not part of the usual visible spectrum for humans, namely infrared. This part of the light spectrum is given off passively by everything as heat. By looking at the differences between the infrared light given off by objects the cameras, we are able to create a picture even when the visible light is too low for most people to perceive. This image can be mapped to show different temperatures as different colors but converting the image into black and white is the more common application.

Next, images can be sent through a type of device that will enhance the image by artificially increasing the amount of electrons the video sensor sees. When a photon hits an image sensor, an electron is generated and the software in the camera is able to map that electron into part of the image. However, if the number of photons given off is too small then the image cannot generate enough detail to give a usable image. This is where “image-intensifier tubes” come in. These tubes take the single photon that hits the sensor and will add additional photons, increasing the ability for the software to make a usable image.

Night vision devices also use materials that are more efficient at converting photons into electrons for the software to create into images. Current military technology uses gallium arsenide to convert photons. Other materials may be developed and this current, cutting-edge tech may filter down to consumer products.

Finally many consumer systems include lighting that is only visible in the infrared spectrum, allowing these cameras to get better images when the subject is closer to the camera. By adding these lights, which cannot be seen except through another night vision device, the user is able to get a better image because there is less after-the-fact enhancement. Enhancements done through software or image intensifier tubes will degrade the image.

Military & Consumer

The equipment used by the military and other professional-level organizations utilize all these same basics but the cutting-edge technology has yet to be allowed into the civilian market. While these top-of-the-line models all work in essentially the same way as the consumer-level equipment, the main difference comes from the lack of active infrared lighting. In a military situation, adding lights to your device isn’t a solid option, so instead they have continued to develop more sensitive sensors and better enhancement devices.

As newer technology is developed by the military and other imaging companies, the enhancements will continue to filter down toward the private and consumer markets.

How to save place in your hose with linear motion systems


Introduction

Improving efficiency and performance are important factors for the success of linear actuators. Nonetheless, linear actuators should also be judged on other criteria, including the ability to help in saving space.  Hence, improving on space ought to be taken into account when choosing among different linear actuators. Linear motion systems that are robust and compact can save on space in the house highlighting the benefits of linear actuators in the homestead.

Configuration

According to Progressive Automation service (also known as PA custom linear actuator service), one of the ways to save space using linear actuators is through having multi-axis configurations. This option is suitable when loading at home, as there is minimal movement of linear actuator, since it is configured to suit the desired results. Belt driven actuators need not be bulky for them to perform the desired wok, and since there can be two mounting configurations; the user can choose to rely both of them.

Sliding

In the loading process, linear actuators can ensure that there is no sliding by holding things together after loading. This creates space as things ate put in more compact positions than they would if there was no form of fastening. In other words, besides loading linear actuators act as fasteners to loaded objects in the house especially the kitchen and store where there are many goods.

Motor mounting

In the process of loading, motor mounting plays an important role, where mounting various components in linear actuators facilitates linear movement and coupling depending on the intended purpose of motor mounting and the design of linear actuators. The more compact a linear actuator is, then the more likely it will take less space while also moving other objects.  However, this function is mostly applicable to linear actuators with belt systems, but other forms can also perform the action.
