    Really Need a Smartwatch

    The first thing to consider is the fact that smartwatches work in collaboration with your smartphone, meaning that even though you sport a wearable tech device on your wrist, it will only work when connected with your smartphone located within a specific range. Smartwatches are designed to provide you with basic notifications such as calls, texts, emails, and most even allow you to reply to them.

    But the chances of you writing or reading an email or reading a long article on a smartwatch are highly unlikely. Unless of course you’re stuck in a dire situation and the only chance of survival is through reading info on the screen of your smartwatch. You may however do these tasks on your smartphone though, and get rid of the extra device you have to haul around on your wrist.

    On a brighter note, there are a few situations where a smartwatch might prove handy such as using it to pay at the gas pump, open your car doors, identify yourself at the bank, or buzz open the door to your school or office. This would eliminate the need to take out your keys, wallet and your ID.

    With notifications on your wrist, you know immediately when you receive an email, text or calls so you don’t have to dig onto your pocket, giving you the ultimate smartphone freedom. And if you’re thinking your wrist will constantly vibrate with frivolous notifications, it’s not rocket science that you can turn on and turn off these notifications as you want.

    You are usually prompted to choose the type of notifications and how you’d like to be alerted – vibrate or beeps or both during the smartphone setup process. Another selling point of smartwatches is their health and fitness tracking capabilities, meaning there are some devices that provide you with several health related metrics including heart rate. They not only track these metrics, but also advise on what to do next such as letting you know when you’re stressed out and how to combat it.

    Unfortunately however not everyone is interested in this data so if it doesn’t matter to you, then this is one feature you will likely not need when buying a smartwatch. New smartwatches when first introduced were goofy looking, clumsy gadgets, but the latest devices all look and work great. Adding to this, they offer several different customization options such as watch faces, straps and even battery life has been considerably improved and now lasts days on end.

    Smart House

    For example you might want to wake up in the morning and already have the coffee brewing, the TV tuned to your favorite channel and the curtains already opened on the east side of the house to let the sun in. All of this is pretty easy, but maybe you also want the outside temperature and weather forecast displayed on your bedroom wall, you might want the water turned on and heated up for your shower. When you leave the house you will want the temperature adjusted in your house, and the doors locked. If you think about your routine around the house most of that can be automated. This is why mapping out your own plan is very important before your start.

    As you can see, so far I am only talking about home automation, however the title of this article is the Smart House. You really can’t talk about a smart house unless you understand home automation and what that means. Simply put, a house can’t be smart unless it is first automated.

    So let me give you some examples of making a house smart. When you are at work and your house is empty, different methods will be used to control temperature. First, your thermostat will adjust depending on the time of the year. As the day progressed curtains would be opened or closed as the sun moved. If it’s winter the curtains would be opened facing the sun to help heat the home, and in the summer the opposite would happen. You would be able to see and control all of this from your smart phone, even when you are away. Before you arrive home the temperature would be adjusted and the curtains would open. The garage door would open as you are pulling into the driveway. The light would turn on as would your TV.

    Benefits of LED Technology

    LEDs are extremely energy-efficient and can consume up to 90% less power than conventional fluorescent bulbs. As such they help to massively cut power costs. Because of low power usage, LEDs are becoming popular light sources in remote areas that use solar panels. LEDs also have long life of up to 60,000 hours compared to 1,500 hours for luminous bulbs. Moreover, they are durable and can withstand shock, vibration and extreme temperature. You can also improve safety by using LED since they produce 3.4 btu’s per hour compared to 85 for incandescent bulbs.

    People are using LEDs in a variety of applications, including residential lighting, aerospace, architectural lighting, automotive, aviation, broadcasting, electronic instrumentation, entertainment and gaming, and more.

    Especially in the micro-projection system, use of LED optics will increase over the years. It is because lighting uniformity and efficiency on spatial light modulators or SLM are two most important factors to gauge performance of micro-projection system. People often use tapered light pipe (TLP) and square compound parabolic concentrator (SCPC) as a beam shaper in LED-based micro projection system. By this, you will get SLM with uniform and efficient illumination.

    However, TLP or SCPC has some disadvantages the primary one been insufficient compactness induced by the working length of TLP or SCPC for the illumination system. To overcome this problem, one can use TIR or Total Internal Reflection lenses.

    Definition of TIR lens

    TIR or Total Internal Reflection lenses are cone-like lenses that usually have rotationally symmetrical designs to distribute light in a rounded pattern. You can use TIR lens to collimated light or to generate a preferred uniform illumination.

    TIR lens manufacturing process

    During TIR lens manufacturing, often the designers do not pay attention to color uniformity, which also limits their application. You can however address this problem through effective color mixing, and use a phosphor-converted white LED module integrated with a compact modified free form to get compact size and high angular color uniformity (ACU).

    Manufacturers design total internal reflection lens with an optimization method to combine and transfer most of the light emitted from LED optics into a rectangular target plane or RTP representing SLM. Typically, TIR lens has six surfaces controlled by seventeen dimensional parameters. Design takes place optimizing dimensional parameters with general algorithms. In order to keep RTP in immovable position with pleasing illumination uniformity and efficiency, designers consider illumination uniformity and efficiency on RTP during the optimization process.

    In the Tracepro program, the simulation result of LED illumination system with the optimized TIR lens shows that the illumination efficiency and uniformity has achieved 61.9%, 76% with considering the limitation angle of light (15 degrees).

    You can manufacture these lenses for multiple LED applications. Manufacturing of different sizes of TIR lenses depends on its optical performance, so one cannot specify FWHM angles, etc.

    Samsung Announces Galaxy Alpha

    The metal form is constantly being promoted for Alpha, even to a point that one would expect that the whole gadget is made of metal. However, it just has a metal casing around the edge, supplanting the plastic painted to look like metal that used to be a part of Samsung’s previous cell phones. The back cover is still made of plastic and is removable to uncover a 1,860 mAh removable battery. The Alpha likewise has a built-in 32GB storage, 2GB RAM, and 12MP camera.

    The Alpha is not intended to be a successor or substitution for the Galaxy S5. The screen on Alpha is more modest at 4.7 inches, yet it is just 1280×720. It does still depend on Samsung’s standard Super AMOLED tech, however. Considering the 720p places, this model clearly lies in Samsung’s mid-range offering.

    Heading off to 720p is a good decision for Samsung. The lower resolution implies that the display will utilize considerably less power than a full HD one would, and that takes into account the utilization of a thinner lithium-ion battery. The overall gadget is consequently more slender and lighter; it is just 6.1mm thick and 115 grams. By correlation, the Galaxy S5 is 8.1mm thick and 145 grams. The screen has a thickness of 312 pixels for every inch, which is great. However Samsung’s AMOLEDs utilize a Pentile subpixel arrangement, which can deliver blurriness with this resolution.

    The lower resolution screen will additionally serve to make the gadget more responsive, to better rival with iPhone. The new Alpha by Samsung has an Exynos 5 Octa processor, which is believed to have no difficulty pushing the pixels on a 720p screen. While the Galaxy S5 was a responsive smartphone, yet Samsung’s gadgets have a tendency to get a bit slower with time. However, Alpha will assuredly evade that. The Samsung Galaxy Alpha is a support against some disappointing trends for the world’s biggest cell phone creator.

    Temperature Sensor for Housed Electronics

    Temperature Sensors

    Even in programmable options, temperature sensors are of a great benefit to anyone who has a 120 mm fan kit and wants to only run it when necessary to save on electricity. This is a great “green” addition to any setup. Many wonder how IC temperature sensors compare to other types; to include RTD, thermocouples and more.

    The best feature of them is the ease of integration with any 120 mm fan kit as well as the many other size fans that are provided by distributors. In addition, they are the low cost solution. Any limitations are not a concern when it comes to electronic system protection applications. This is because they have a smaller temperature range.

    Simple Sensors for Simple Systems

    These sensors can make it easy for anyone to add protective elements to any system. Temperature once the 120mm fan is install depends on many things. Among them are air flow, thermal resistance, ambient temperature and output power. Fans reduce amp temperature but there is always the issue of noise.

    That’s why installing a sensor is smart. It makes the 120 mm fan kit only run when the temperature is that high that forced-air cooling is required. In turn, this minimizes noise output. The result of a well-designed system is reduced noise, and in most cases the fan won’t even be needed unless the components are being overused. When mounting the sensor, the best spot is on the other side of the circuit board, or away from the heat sink.

    The sensor should be mounted in a place that provides good correlation with die temperature. If the heat sink is mounted against one side of the printed circuit board, mounting the sensor on the other side of the circuit board works well. IC1 consists of a temperature sensor, a 1.25 V voltage about, and a dual comparator.

    Finding the Right Products

    There are many suppliers that give both the 120 mm fan kit, mounting supplies, filters, temperature sensors, cords and everything one needs to build the perfect setup at home. Often times, they come at deep discounts when ordered in bulk. However, if they are needed singly that is welcome too.

    Further, the experts that run these supply stores that are found in brick and mortar locations as well as online are usually happy to help anyone to choose what they need. No one should be hesitant to delve in and start building the perfect cooling system to protect their components whether in a residential or commercial setting.
