LCD Video Wall Systems for Modern Control Rooms

Posted on by

The best display technologies of only 10 years ago are considered primitive by today’s standards. They were a poor return on investment because they were expensive and added little to the control room’s comparative ability to manage critical information. Expensive large format front and rear projectors were the primary choice. They were undependable, relatively low resolution, and required expensive maintenance contracts because they rarely had redundancy when a projection lamp failed. Then you add expensive, bulky hard-wire switchers to bring signals to the projectors and you still don’t have the capabilities of today’s most basic LCD video wall driven by a computerized controller. In fact, much of what was considered state of the art at the time was just “eye candy”; it looked good, but did little to advance the performance of the people using it.

 

What is considered a modern video wall system?

It employs a matrix of displays driven by a sophisticated computer that allows the operator to acquire and display more information faster than with older methods. This also means faster and better decision making. These are the type display systems that do much more than merely connect a switch between computers and individual displays mounted to the wall. These systems allow you to reach out on the data network and bring in an almost unlimited number of sources to the video wall, and as the network grows, it is unaffected except to say that more screen surface could be needed to display more information than before.

 

The growing popularity of LCD video wall systems

These are now more popular because they meet most performance requirements, require less investment and occupy the least amount of floor space. In fact they can be mounted on the wall taking up only 4-6″ in depth. These high resolution displays form a matrix or single pallet. Each display’s ultra-thin bezel is designed to minimize distraction when enlarging images across multiple displays.

 

These are relatively easy to install and require little maintenance or adjustment. They are rarely repaired because it’s easier and faster to replace than repair, however the typical industrial LCD display will run dependably for thousands of hours.

 

I should point out that these systems perform the same as video walls with other type displays because it’s the video wall controller, or brain of the system that acquires and displays what is shown on the video wall. The video controller (processor) doesn’t see the number of displays, or the type or size of displays. The controller sees the matrix of displays as a single display allowing the images to be easily placed and sized anywhere on the overall screen surface.

 

There are two types of LCD video wall used in control rooms; wall mounted or freestanding cabinet. Wall mounted systems require that the wall be reinforced and cannot be installed or easily relocated like a 12″ deep cabinet. The cabinet is modular and stores all supporting electronics in the base and as a result, can be easily expanded and relocated as requirements change.

What is a GPS Antenna?

Posted on by

A GPS antenna is a device that helps boost the reception signal to a GPS unit, whether it is a standalone unit or an embedded unit. Often a GPS antenna is used in a situation where the GPS unit itself is somehow removed from a line of sight to the sky, as in a car, to help the GPS “see” the sky without having to be moved. GPS antennae may be purchased for a range of budgets, or cheaper home versions can be made with fairly common components.

 

GPS, or the Global Positioning System, is a satellite system originally developed by the United States Department of Defense. It utilizes more than two dozen satellites orbiting the Earth to allow receivers on the ground or in the sky to tell exactly where they are, by receiving heads off of multiple satellites. Using this location, devices can detect not just latitude and longitude, but also altitude, and even heading and speed. For years, GPS was reserved for military use in the United States, but following a directive by President Reagan in 1983 it became open for civilian use.

 

Civilian GPS contains certain restrictions, imposed by the US government to make sure hostile forces don’t use the technology in missiles. As a result, consumer GPS isn’t capable of operating when moving at more than 515 m/s at more than 60,000 feet (18 km). Throughout the eighties and early nineties GPS was used primarily in commercial avenues, such as on fishing boats, in airplanes, or for geographic surveying. In the late nineties it began gaining popularity for consumers for hiking or for driving, and by the new millennium cars were being equipped with built-in GPS to give driving directions, and cell phones began having included GPS for directions and location.

 

A GPS unit has a built in antenna, which is usually quite small and located inside of the unit. While this will likely function in ideal circumstances, such as when in a desert moving at slow speeds or staying still, it may not work as well as one would like in more trying circumstances. A GPS unit likes to have a clear, unobstructed view of the sky, to best receive the microwave signals that allow it to communicate with satellites. For GPS units inside of cars, this can be problematic, so often an external GPS antenna will be used, mounted to the outside of the car with a magnet, and connected to the unit itself by a cable.

 

In situations such as heavy canopy cover while hiking, the small GPS antennas built into a consumer unit also may not be able to ideally communicate with the satellites. In this case, a larger, more advanced GPS antenna helps the unit overcome the environmental challenges, to give a clear signal. Similarly, moving at high velocities can overwhelm a smaller, less sophisticated antenna, and an external device can boost the signal.

 

There are a number of different types of GPS antenna, with the patch and Quad Helix styles being the most popular. Both are roughly equal in efficacy, although many people find the quad helix to have a slight bit more sensitivity. Other types of antennae include microstrips, of which the patch is one configuration, planar rings, and spiral helices.

 

Established in 1996, Cirocomm is an outstanding manufacturer of GPS antenna in the industry. We also provide various antenna series, including dielectric filter, Glonass, WIFI, GSM, NFC antenna series and more. If you are interested in and need more details about GPS antennas, welcome to visit our website and send inquiry to Cirocomm!

Video Wall Software Improving Content Management

Posted on by

Let’s face it: today’s technology is miles ahead of the technology from even ten years ago, and it’s improving at an exponential rate. Standard definition is hardly standard anymore; now 1080p high definition is the norm for most types of screens. And the new high definition – 4K Ultra HD – is a full four times sharper than regular HD!

 

With flatter, thinner screens that support ever higher resolutions, it’s clear that our hardware has surpassed our expectations and given us the possibility for the absolute top-of-the-line screen quality when it comes to audio/visual solutions. So what’s left? Where do we go from here, and how can we possibly improve upon what we already have?

 

The answer, which many overlook, is content. Sure, we may have the means to display amazing images and videos on super-sharp screens, but we also need the right content to actually put on those screens, and an easy way of doing so.

 

That’s why video wall software has become just as important as the actual hardware. Video wall installations are ideal for a wide variety of environments, from retail to education to entertainment, but often the content management systems can be complicated and time-consuming.

 

With the right video wall software, you should be able to manage your content with ease. That’s the next step in technological innovation: not just improving the hardware, but improving the ways that we add and manage content. We’re moving towards a world where content is king, and management that is both intuitive and user friendly is the name of the game.

 

Software also adds a level of customization that allows you to really make the content reflective of your identity or brand. Customization is increasingly important in today’s world where we are constantly inundated with information that can seem generic. With software that lets you customize your content, you can create something that is completely unique to you and your company. This is perfect for when you want to stand out in advertising or create dynamic presentations to showcase your business.

 

The right video wall software allows users to program and schedule content so that it will play at specific times-perfect for planning ahead. There are usually plenty of configurations available as well, like picture in picture. Software is also useful when you want to use a combination of different media sources, such as CD/DVD players, cameras, the internet, and more.

 

The future of AV technology is content management, so instead of just thinking about the right hardware, consider also a system that comes with integrated and intuitive software.

Overview of Power Capacitors

Posted on by

What are they?

 

Power capacitors work by acting as a reserve power bank; they store the charge rather than being the source of power such as the battery. When you are listening to your music, and playing a heavy sub-bass note, the power will draw from the capacitor rather than from the battery so to ensure that the rest of the car will not be starved of power i.e. the headlights dimming. It will act as a buffer so that that the power being delivered to the amplifiers will not drop below the recommended voltages and be steady therefore reducing the risk of damage to the components.

 

So what power capacitor to choose?

 

After doing a bit of research, the general rule seems to be 1 farad per 1000 watts of power that your system is running at. So using that, a 1.5 farad power capacitor should be ideally suited to a 1500 watt system. There is a large selection of power capacitors available out there, for example, this power capacitor is a 2 farad power capacitor designed for smaller systems, this is not to say however that it will have a reduction in performance, however for those systems that require more power, a power capacitor with a higher farad will be able to deliver for longer and will usually be of a higher build quality.

 

How to install the capacitor

 

Ideally the capacitor needs to be installed as close to the amplifiers as possible. The capacitor requires a 12 volt positive from the battery and a separate ground, to the amplifier; so that the 12 volt positive is ‘inline’ with the terminal from the battery and the amplifier. The amplifier 12 volt positive is then taken from the capacitor while the amplifier is usually grounded separately as it is important to use as short a ground cable as possible to reduce any potential ground interference.

 

When you need to consider other alternatives

 

Power capacitors will not always be of help when you are listening to music, if the lights for example dim down, and stay dim, this indicates there is a deficiency of power and there are other methods of solving the problem, it could potentially be that the battery is not able to generate a charge sufficient enough to meet the demands, so installing a higher cranking battery is usually the common solution however it is possible that upgrading “The Big Three” may also solve the issue(see below for more details). It is also important to check that the current alternator can produce a charge that will be sufficient with a larger battery.

 

‘The Big Three’

 

The big three is a popular upgrade. It consists of upgrading three wires in the car to ones that are much thicker. As a result of using much thicker wire, more current is allowed to flow through; hence the overall effect seen will be that the voltage running through the car will be higher. The three wires that are upgraded are the wire from the alternator to the battery, the engine ground to the chassis and the battery ground to the chassis. It is common, but not always, that people will choose 0 gauge power wire when going about the big three upgrade. This is vital again to ensure that the voltage delivered to the amplifiers does not drop so low that the risk of damage is possible.

 

Conclusion

 

So in conclusion, there is no hard or fast answer to if a capacitor is necessary or not. However capacitors may have benefits if used appropriately. There are large selections of capacitors; some come with digital volt meters, distribution blocks etc., while others are purely chosen for aesthetic pleasure, I myself went for a 4 farad power capacitor with a built in digital volt meter with an LCD display so that it was something I was able to display and looks pretty damn cool.

Gamma-Resistant FRAM RFID Chips Enable Cradle-to-Grave Tracking of Medical Devices

Posted on by

Japan’s Fujitsu Semiconductor Ltd has developed a radiation-resistant radio-frequency identification (RFID) chip with full traceability. When exposed even to small doses of gamma radiation, the memory of conventional RFID tags with E2PROM or Flash is completely erased or corrupted. By contrast, Fujitsu’s FerVID family of products with ferroelectric random access memory (FRAM) can withstand up to 50 kGy of radiation, more than twice the industry standard.

 

FRAM is a type of memory that uses ferroelectric thin film as a capacitor for storing data, which is not lost when power is shut down. It is a high-performance, low-power technology that combines the benefits of nonvolatile memories (E2PROM and Flash) with high-speed RAM (SRAM and DRAM). Compared to other nonvolatile memories, key advantages of FRAM include a fast read/write speed, low power consumption and high endurance (10 billion read/write cycles). This tamper-resistant, secure memory is not affected by magnetic fields. Most importantly for medical and pharmaceutical applications, FRAM is radiation-resistant. FRAM’s properties combined with the tracking capabilities of RFID simplify the tracking process for medical devices and help to ensure their safety.

 

“If you embed the FRAM RFID tag in medical bags, filters, surgical instruments, syringes, tubes, or other single-use products at the time of manufacture, you can track and manage the devices over their entire lifecycle from manufacturing to sterilisation, shipping, receiving, storage, use and disposal,” says Junichi Teramae of Fujitsu Semiconductor’s Solution Engineering department. “The data stored in this tag can be shared with electronic medical records at hospitals, if NFC smart phones or tablet terminals are used as an RFID reader,” he adds.

 

The FerVID family of products, with the combination of high-impact thermoplastic materials, has also found success in medical products that undergo autoclave sterilisation. Last year, Fujitsu supplied FerVID family products to Japan’s second-largest printing company, Toppan Printing Co., which makes tags for use with disposable gauze, surgical tools, sterilisation containers and other medical products. The new RFID tags, which are fabricated from Radel polyphenylsulphone resins formulated by Solvay Specialty Polymers in the United States, withstand the high temperatures, pressure and humidity produced by the autoclave process.

 

Fujitsu’s FerVID family offers HF and UHF FRAM RFID products. The ISO 15693–compliant devices cover the 13.56-MHz operating frequency and feature 2-kByte and 256-Byte memories, respectively. In the 860 to 960 MHz UHF band, Fujitsu offers 4-kByte and 64-kByte FRAM devices, compliant with the EPC global C1G2 standard. In addition to standard ISO commands, the products feature anticollision capabilities and custom fast read/write transmission commands.

 

Founded in 1999, SAG Securitag Assembly Group is a RFID technology products manufacturer in Taiwan. We provide FRAM RFID for customers. Ferroelectric RAM (FRAM) is a memory technology that combines the best of RAM and ROM. FRAM is ideal for applications that require high-performance, non-volatile and large memory. FRAM offers several major advantages over EEPROM, including its speed, endurance, low power consumption, security, and tolerance for radiation.

 

Looking at all these features, SAG build hard tags with MB89R118/119/112 powered by Fujitsu to target demands from industrial and health care sectors. Constructed by overmolded process, these tags are certified to have its outstanding capability to reach a heavy-duty level.

How Capacitors Work

Posted on by

Capacitors, which were previously known as condensers, are electrical components that store electric charge temporarily. Although capacitors may come in various shapes and sizes, they all have one function in common, storing electrical charge. The capacitor has two terminals that are separated by a non-conducting substance called dielectric. The dielectric can be made of film, paper plastic or air whereas the terminals can be made of aluminum or other conductive metals. One can even make capacitors at home by using two pieces of aluminum foil and a piece of paper. Although it would not be a good capacitor, it would still be able to function.

Although any non-conductive material can be classified as dielectric, only specific materials are used to construct capacitors depending how it will be applied. The dielectric can dictate what type of capacitor it would be and its application. The type and size of the dielectric used would determine the application of the capacitor. Some capacitors may be ideal for high frequency applications whereas others may be better at high voltage applications. They can be used for a variety of applications ranging from torch lights to huge capacitors that can power buses.

Capacitors that use air as a dielectric material in them can be used for radio tuning circuits. Capacitors using Mylar can be commonly found in timer circuits such as alarm clocks and glass and are often used as a dielectric material in capacitors that require high voltage applications. Applications that have high frequency such as x-ray or MRI make use of ceramic capacitors.

The amount of charge that a capacitor can store, which can also be called its capacitance, is measured in units called farads. A capacitor unlike a battery can take only a fraction of a second to completely discharge. A battery may however take minutes to do so. Due to this feature of capacitors, they are often used in the electronic flash on cameras. When you click a picture the flash come and goes off immediately. This is a good example of a capacitor discharging all its stored energy in a fraction of a second. When the flash is not clicked, the battery charges it up and it discharges this energy when a picture is clicked using flash. This however can be dangerous as capacitors such as those in television sets can contain large amount of charge. Therefore, if you were to open your TV set and touch the fully charged capacitor it could kill you.

Capacitors have definitely improved electronic devices tremendously and as well as aided in the advancement of technology greatly. However, when using electronic devices that have capacitors that can store a huge charge, one should always be very careful.
