Over 27,000 employees, across many different roles and departments, make up the DIRECTV family. The team is expected to expand even further once their proposed acquisition by AT&T is finalized. For a college student, graduates, and professional job seekers, there is growing reason to turn to a career with DIRECTV. With the opportunity to develop a lifelong career which is challenging, fulfilling, and rewarding in equal measure, DIRECTV is fast becoming a popular destination for talented individuals looking for that dream career.

What Tech Line Actuators Do

As industrial environments are becoming more and more advanced and connected, actuators will require to be used more and more often in the industries. Actuators will ensure perfect and timely delivery of communication features and the intelligence needed to run the industrial plants. The line actuators can provide high-performance processing that is power effective, an advanced human-machine interface feature, and support for high-speed wired or wireless communication within the industry. Actuators can control the human Machine interface that enables smooth signaling and controlling the state of industrial automation equipment. Actuators can be fitted with sensors that are used to position, detect and identify objects or even the rotating axis in a factory automated system. Industrial Communication Automated actuator systems are the heart of effective Industrial communication. Many of the industrial applications such as moving machines, motor combinations, pulleys, back fixtures, piston rod eye and spindle pitch require very elaborate communication options. To meet the increasing demands of field buses and real-time Ethernet solutions, automated actuator systems will be the solution to these growing needs.

Few tips for building reliable SPI interface

Many SPI tutorials use the standard notation of bus design where each device is directly in parallel connected to SCK, MISO, MOSI, and CS lines. This usually works without a problem, but there can be problems when more than one SPI device is on the bus. There might be several issues that can occur on poor design. Here are three suggestions for better SPI improvements: Pull up resistor helps to prevent the response from multiple devices at once. This might come from poor software design when CS pins aren’t appropriately initialized. The second problem is with MISO pin. Some SPI devices don’t enter tri-state even when CS is pulled high. So when talking to other SPI devices this will cause failures. Be sure to check if SPI device supports tri-state when inactive; otherwise, add external tri-state buffer like 74AHC1G125. And last thing is SPI transactions. In systems where multiple SPI devices are used, there is a risk of using different settings that were selected on different devices. Most importantly, transactions can ensure exclusive use of the SPI bus when needed….

How to build self resetting load switch in embedded circuits

In many microcontroller projects, we need to control loads such as relays, bulbs, or motors. From microcontroller side, we simply send a signal that turns the device on or off. Microcontrollers usually don’t care what’s going on further – is load switched on, or is it failing? Of course, we can build feedback and read voltage from sense resistor and switch load off in case it draws too much current. But sometimes, relying on the microcontroller to work reliably when it can be hung due to overload conditions is not accepted. We need to use passive methods of protection. Few additional discrete components can make a big difference. Anthony suggests a transistor-based overload protection circuit, which doesn’t do anything in normal conditions. But once the current exceeds the limit, it shuts off switching the MOSFET transistor immediately, thus probably saving the rest of the circuit from frying. A straightforward solution is to use NPN transistor, which base is connected to the load current sense resistor. It value is selected so that voltage drop on load threshold current would open transistor…

How to Install GSM Repeater

Mobile technology has opened a lot of doors for communication in places that weren’t always possible. Today, you can use your cell phone just about anywhere. For this reason, it can be even more frustrating when you experience a weak signal in your home or office. The best solution for this problem is to install a GSM repeater in the area where you are experiencing low reception. What is a GSM Repeater? A low signal can be caused by a variety of conditions, such as interference, thick walls or other obstructive structures, or the distance from the cell tower. Since cell phones operate by transmitting radio waves from one base station to the mobile unit, the GSM repeater acts as a middle receiver, in which the signal is amplified before being sent to the cell phone.

Forget about Weak Signal with Mobile Phone Signal Booster

Have you ever had the situation in the office when you desperately needed to call your client and agree on a deal, but your mobile phone kept breaking, saying that there was no connection? The Old Story of the Old World The story of people complaining that their mobile phone is always out of coverage is not new and quite typical worldwide. This very problem is rather painful for workers whose work efficiency depends on calls. Unfortunately, it can be a typical problem of many multistoried buildings, where most office plankton works.
