Embedded Control - Record Layouts Improve Database and RFID Sensor Testing

Software application designers and hardware application developers are working as teams to incorporate control-record layouts into end-to-end XML services for RFID networks. Using these newly formed XML tag sets made up of customized control-records has improved the design and development scenarios across diverse hardware platforms, operating systems, applications, and databases.

As software application developers begin to build RFID-and-sensor networks within key growth areas, it has become common place to witness recent deployments of control-record structures embedded in sensors and their supporting software. These control records contribute immensely to the major functions of any RFID sensor application including inputs, data-lookup and storage, interface programming and outputs.

These five major features are now incorporated into the application as a new and more efficient XML and database schema. This improved configuration has proven to meet growing demands to test multi-vendor RFID and sensor products for their ability to withstand extreme conditions. These conditions include excessive heat and cold, shock, humidity, vibration, altitude, pressure and all are reliably monitored using the new control-record layout approach.

The key design feature in the programming arrangement described in this article is the idea that an intermediate control record receives and distributes signals to and from the software and hardware sides of the full application. This nicely integrates selected signals from both spheres of operation and allows an interface to adapt dynamically to different device types. As new devices are attached and configured with the application, no appreciable interference is noticed in the originally attached devices.

Because the embedded layout of many types of devices can be addressed through the use of control records, new applications are provided with better XML testing languages. Additionally, this feature provides designers with the opportunity to introduce database simulators for a more accurate and dynamic portrayal of RFID and Sensor operation. This dynamic portrayal is added to the accumulated testing history and a better picture of performance emerges.

As RFID becomes more widely deployed, network reliability, security, and data integrity become increasingly critical. And for most companies, the task of ensuring those three things will be overwhelming and complex, especially across multiple hardware platforms and configurations and diverse supplier and partner networks and databases.

But because it is now feasible to virtually attach these control-record layouts to alleviate some of the major complexities associated with the required tests, any company can develop new products that may have been prohibitive in the past.

How A Humidity Sensor Can Help You Improve the Air Quality

What is humidity?

Humidity is the total amount of water vapor or moisture present in the air. You, your family members, and even your pets produce moisture at the time of breathing. Did you know, even your indoor plants can create moisture? Moreover, we use water in various indoor activities like bathing, showering, washing clothes, cooking, and dish washing. All these can form moisture, that, if not controlled or measured properly with the help of a humidity sensor, can cause serious health problems. And, if you run a health center like hospital, blood bank, and pharmacy then you keeping track of the temperature is an absolute necessity.

When does humidity becomes a problem?

Certain amount of humidity is required for the comfort and health of you and your family members. However, too much or too little amount of humidity can create a lot of problems. Such problems generally becomes intolerable when all the windows and doors are closed and the indoor air cannot circulate properly.

How a humidity sensor can help

It is a device that is used to measure and get the report of the relative humidity present in the indoor air. If you or any of your family members suffer with illness affected by humidity, then you can consider buying a measurement device as a part of your heating, ventilating, and air conditioning (HVAC) systems. Apart from that, they can also be used in wine cellars, cars, commercial HVAC systems, and meteorology departments to predict and report weather.

How does it work

Such devices sense relative humidity (RH) and measures moisture and air temperature. Wondering what is RH? Well, it is the ratio of the total moisture present in the air and how much temperature the air can hold. Generally, the warmer the air gets, the more moisture it becomes. That is why relative humidity or the ratio fluctuates in temperature. A humidity sensor will sense the ratio and convert it into digital reading to show the amount of moisture.

What are the options available

However, there are different types of humidity sensors available in the market but not all of them can provide precise measurement of temperature and humidity. Moreover, if you do not want to get into the hassles of wires and huge devices, then you should consider buying a compact WIFI device for your requirements. These devices are accurate, small in size, and affordable as well.

Want to buy superior quality humidity sensor from a company that is an industry leader and is renowned for manufacturing WIFI Sensor products? Then, SensoScientific, Inc. is the name you should trust.

Graphite & Talc Powders - Improve Seeding Yields on the Farm

Graphite and Talc Powders: Increase Crop Yield Through Better Seed Planting. It is common practice in the mid-west and some other isolated regions to add graphite and talc powders to improve the performance of seed planters. When planting seeds in high humidity environments there is a tendency for the seeds to bridge in the hoppers and not flow consistently causing poor distribution of the seeds.It was found that adding graphite to the seed in the hopper created improved flow and got rid of seed bridging in the hopper improving distribution and increasing crop yields. Also the graphite powder added lubrication to mechanical parts of the planter exposed to the seeds. Depending on the composition of the graphite powder, that is the graphite content, the higher content the better lubrication and less wear from the ash content.

Graphite is used in mechanical planters and the introduction of more advanced planters in the mid-nineties using vacuum and optical seed sensors required a different additive which was talc powder.Talc powders performed the same functions as graphite powders in preventing bridging, reducing wear on mechanical components and its chemical composition allowed its use in the newer planters introduced by John Deere, etc.The talc powders are sensitive to humidity levels and agglomerate easily which can be a problem when used in the early morning or during rainy conditions. This has been overcome by adding some graphite powder to the talc which improves the powder flow without having negative effect on the newer planters.

The packaging of the powders has evolved to meet application conditions since the early cans were difficult to apply in windy conditions and the black graphite powders sometimes would blow back on the operators. The introduction of pourer cans and 5lb jugs has got rid of that problem.Wilmar Graphite Company, who the author works for, now makes less than case quantities available for Talc Powder and 80-20 Talc Graphite Powder, Slide Coat Graphite and Clean Deck Graphite, in order to enable individual farms to buy direct. Information is available at http://www.Farm.WilmarGraphite.net

Nest Learning Thermostat to Improve the Comfort of Your Nest

Background

Steve Jobs will not only be remembered for his visionary genius in the lifestyle changes his technology brought to the media and music genres, but also for his creative team. One example is Tony Fadell, the hardware engineer that approached Apple with the original idea of the iPod. The iPod did for music what the Mac did for computers. Both brought technology to a higher level. Since the iPod's introduction in 2001, it has evolved many times. Over 8 years Fadell led the team that produced 18 generations of the iPod and 3 versions of the iPhone.

When Fadell left Apple in 2008 he promised Jobs that he wouldn't compete with Apple. Fadell took time off to figure out what new idea would excite his creativity again enough to bring him out of retirement. True to his word, on October 25, 2011 Fadell revealed the project he and his copartner, former iPhone software manager Matt Rogers, have been developing for the past 18 months. So what is this new revolutionary product? A thermostat. Yes, that's correct, a thermostat. But this is no ordinary thermostat. This is the iPod of thermostats. When building his green home, Fadell found a less than impressive selection of thermostats, even high-end options. He researched and found that a properly programmed thermostat can amount to a 20% energy savings and a change of just one degree can cut energy costs by 5%. Approximately 50% of a home's energy bill is controlled by a thermostat. Why does it have to be an ugly beige box on the wall? With these facts and his engineering knowledge, he formed the Nest Labs and developed the Nest learning thermostat.

Aesthetic style and Hidden Functions Menu

As with the iPod and iPhone, Fadell adds a unique aesthetic style to the simple round dial made of high quality stainless steel rings which reflects the light and color around it. The rings act as a dial that can be turned left or right in order to manually adjust the temperature up or down. The main menu is cleverly hidden. In order to access the main menu, the black button in the middle is tapped and the menu lights up. The menu includes an away function that allows for optimum energy savings when the user is not at home. Fadell incorporated the smart phone technology that allows remote access from an iPhone or iPad app.

Learning Program and Energy Savings

Instead of a programmable program that only around 10% of consumers bother to set, he developed a more user-friendly interface learning program. After gathering pattern information, the program eventually programs itself with little input from the user. The green leaf is a visual feedback that displays when heating or cooling wisely. When the temperature is initially set by the user, the thermostat will adjust itself by an almost undetectable 1 or 2 degrees resulting in a 5 - 10% instant energy savings. The Nest includes five different sensors - temperature, humidity, light, near field and far field. The sensors can sense when the user is a home, sunlight from windows, and room lighting. The latter two sensors act much like the motion sensor of a security system.

Fadell emphasizes that his product focuses on the end-user and their needs. As an end-user, he desired a product that would save energy, be appealing and easy to use. As an engineer, he was able to draw on his experience and develop the product and offer it to the market. The cost of $249 may at first seem somewhat high, but the potential savings factor will more than pay for itself. At the time of this writing the initial presales have temporarily caused the shutdown of new orders until early 2012.

How Can a Dehumidifier for Your Home Improve Your Environment and Health?

What is a dehumidifier? How does it work?

A dehumidifier is an electronic device usually used in the workplace or in the home. It is used to reduce the humidity in the air -that is the measure of the amount of moisture in the air. A dehumidifier works by controlling the humidity by sucking in the air in the atmosphere through a fan. Once the air is inside of the device is enters the section which contains cooled coils. At this point condensation is used by cooling the air so that it reaches its maximum threshold for holding moisture and converts into water droplets. These water droplets then drip down the coils into a water storage area. The air is then reheated to a temperature usually controlled by a built in humidistat so that the humidity levels are kept at a desired level.

In terms of water storage the dehumidifier will have a built in water reservoir and a sensor to ensure that it does not overflow - this means it switches off automatically when it reaches a certain capacity level. Obviously, this is potentially a problem if the device is in a high humidity area and needs to be switched on all the time; however this problem can be dealt with effectively by the use of a hose to drain the water away or you can get a dehumidifier unit with a condensate pump built in that will ensure the water is regularly pumped out of the device and down a drain.

Different types of dehumidifiers?

There are several types of dehumidifiers but which are the best humidifiers and which one is right for you? Well the choice can be made initially by your requirements. If you are looking for dehumidifiers for home then you have two choices - a portable dehumidifier or a whole-house dehumidifier. The portable devices provide a small, lightweight option, often made of plastic meaning they are very cost effective. These devices are designed to give their best performance in small spaces such as bedrooms or kitchens and as such will be less effective if in a large open space.

If you are looking for an option to control the humidity of your entire house and basement then you will be looking for a larger unit. These larger units will need to be professionally installed, at an obvious additional cost but will provide a much wider area of service and can be especially useful if you have very high humidity areas or a storage area which needs to be carefully controlled. The whole house units will be fitted alongside the heating and air conditioning systems of the house and will work in parallel to work more effectively.

The third choice is a restoration humidifier and these units are more heavyweight machines that are used with heavy water damage so will not be used as dehumidifiers for the home.

Is it expensive?

Using a portable dehumidifier obviously comes with the fact that it uses a lot of electricity. Obviously this varies unit to unit exactly how much electricity it will use and how much this will cost and it is important to balance this into benefits of using a dehumidifier. Using a dehumidifier will give the room a higher perceived temperature meaning that you will be using your heating less which will obviously compensate some of the electricity costs. On top of this you have to factor in the fact that if you are in the workplace then your work efficiency will be much higher in well controlled conditions than in a high humidity office or if you are at home then you will enjoy a less stressful life in general by feeling refreshed. Another way you can reclaim some of the cost is by recycling the water that the dehumidifier produces and using it to water your plants and flowers - extending the benefits of costs involved. It is important to balance all of these factors when choosing the best dehumidifier for you as they will all have different costs for the unit, electricity usage and water storage.

What are the benefits?

On top of the fact that a dehumidifier makes the atmosphere there are many health benefits from getting a dehumidifier for your home. The most noticeable problems that can be seen to be caused by high levels of humidity are mold and fungus forming on your walls, wallpaper peeling away, condensation forming on your windows as well as a general feeling of stuffiness in a room. All these problems are caused by high humidity and especially in the case of the mold it can cause serious illness. Once it forms it can be difficult to get rid of, so it's much better to be prepared and fight it before it forms! On top of this limiting the humidity in the air can help clear the air making your breathing better and fighting off any colds or coughs. A dehumidifier can be exceptionally useful in areas of storage such as basements (which often suffer especially badly from high humidity problems) as they are often the centre of the causes of damp and leaks and so dehumidifiers for basements are very popular.

Disadvantages/problems?

The only problem that you could mention with dehumidifiers is that of the additional cost and it is important to balance this against the whole range of benefits you will gain from installing the unit in your home or basement. The best thing to do is get a list of the best humidifiers for your home and compare the costs and advantages of each and then choose the most suitable one

Overall it is not hard to see how dehumidifiers for home, basement and workplaces have become very common and useful in areas of high humidity and it is well worth the investment to improve your health and lifestyle.

Unique Gardening Tools to Improve Your Garden

Innovative garden tools for the outdoor garden that make gardening easier for the gardening enthusiast are always being invented. One of the newest gardening tools that is presently experiencing rising popularity is a Topsy Turvy hanging tomato planter. Using a Topsy Turvy hanging tomato planter allows you to grow your own juicy tomatoes much easier, since the plant grows upside down. Many upside down containers come with detailed instructions to make growing your tomatoes very easy. Hanging tomato planters that grow plants upright can also be found at your local home improvement store.

One nice thing about a hanging tomato planter is that it helps gardeners to more easily harvest their tomatoes than they would for a traditionally grown tomato bush. The benefit of a hanging tomato planter goes further than ergonomics though; this is a gardening tool that also permits people to grow tomatoes in confined spaces. You will not need a large garden when you put this gardening tool to work. The ability to grow tasty tomatoes in a hanging container spans from homes with a large yard to apartments with no yard. A Topsy Turvy hanging tomato planter can be hung on a small porch in a sunny spot and yield tomatoes as fabulous as those growing in a flourishing garden.

Another innovative gardening tool that is receiving rave reviews is the EasyBloom garden sensor. Many people who really love their plants have taken to using a EasyBloom garden sensor to know exactly what their plants require. A EasyBloom garden sensor has two prongs that are placed into the ground where you are planning on placing a plant or tree. While the plant sensor is kept in place for 24 hours, it then goes to work to track conditions like the amount of sunlight, temperature, and humidity in the soil.

After the 24 hour period is done, the EasyBloom garden sensor is then plugged into a computer which takes you to a website that gives you the results of what your plant may need to thrive. The information the plant sensor has gathered will be presented to you. What you can learn from this is how to select the right plants for that particular area of your garden. Additionally, a plant sensor can be used to diagnose issues with plants that are already planted in your yard. Utilizing the plant sensor in this situation may alert you to deficiencies the plant is experiencing and guide you to correcting the problem.

What the EasyBloom garden sensor does not do is advise gardeners of whether or not a certain plant is best suited for a particular planting zone. It also cannot determine the pH levels in soil, nor can it save data once the data has been collected by the website. As technology improves, it is likely that the EasyBloom garden sensor device will improve over time, allowing users the ability to retain the data which has been collected.

Superior hand garden tools should make gardening chores easier for gardeners. That's exactly what these two unique gardening tools accomplish. Test out a Topsy Turvy hanging tomato planter or EasyBloom garden sensor in your yard this year and you will undoubtedly experience easier growing!
