The Samsung Galaxy Ace S5830 is an international version of the S5830L quad-band phone. The S5830 is manufactured for the international market and features dual-band operation in the 900 and 1900 MHz frequency segments. It is a 3G device recognizing DLNA networking. If the ISP employed is DLNA-compatible, the dual-band Galaxy Ace is capable of 3G wireless network speeds.
Since the Galaxy Ace S5830 recognizes WiFi networking standard 802.11 b/g/n and employs the Android operating system (v 2.2), it is capable of not only recognizing local public hotspots so one can stay in touch with the Internet for up to 11 hours on one battery charge, but it can also be integrated into a home network that uses an older router than may only recognize 802 b/g, which means that you can use and update this smartphone as part of your home network. It also makes heavy use of Bluetooth technology so you can sync other devices to it or you can sync it to your PC via Bluetooth. The 5 MP camera offers you instant image sharing and with the proper amount of memory one can also handle some fairly sophisticated videography chores.
Since the Android operating system is tied to Google and its wide variety of open apps, one can have access to 200,000 or more apps at this moment. From the manufacturer, it is equipped for to keep in touch with email, texting and SNS so that one can stay instantly in touch with not only friends, family, but also the office through texting and web apps offered.
The S5830 offers a minimalist, yet sophisticated approach to networking as it does recognize Google’s networking and should recognize Google’s latest social networking option, Google+, an app that allows one to set up a “social circle” of friends, although it does offer a number of safeguards so that one can keep in touch with those whom one wants to keep in touch with, while keeping others out. It is a nice piece of work that helps ensure a bit more network security than other social networking vehicles are offering. They will likely get to this point, but Google will probably be offering even more sophisticated apps. The whole smartphone market seems to be in a huge state of flux at the moment as each network struggles to maintain its top stop.
Google, though, since it is available for PCs and smartphones because of its tight linkage to Android is likely to maintain a slight edge in this department. Speaking of edges, the S5830 offers predictive texting as it fills in the blanks after one has keyed one or two letters. The S5830 also offers SWYPE technology that lets one hit one of two spots on the QWERTY-like keyboard touch-screen app and the Ace fill in the letters one is typing, another type of predictive typing mode. The sensitive touch-screen quickly updates as the Ace runs on an 800 MHz processor and one can install up to 32 GB of microSD memory so one has enough memory to make up for the lack of a super-high-speed processor.
The fully integrated touch-screen also lets one organize contacts into four categories so that one can have the type of display one needs. For example, if one likes a history of emails or texts, one can use the organizer to display the history. Other features of this organizer include allowing one to organize around activity, mail or type of information. All of this information is displayed on a high-resolution HVGA 3.5-inch screen.
The Ace is a compact smartphone that offers one a high-degree of flexibility and web integration thanks to its operating system in a package that is 4.2 inches by 2.4 inches by 0.4 inches and that weighs 3.5 ounces. It also features built-in GPS capability with A-GPS support so that with access to Google Earth and Maps, available through Android apps, the Ace can also act as a sophisticated navigation device as well as a smartphone.
Do you worry about your moles? Most people have anywhere between 10 and 40 moles on their body, and the good news is that most of those moles do not become cancerous. Moles can appear flat or raised, and can be pink, tan, brown or the same color as the skin.
Skin cancer accounts for almost 50% of all cancers in the U.S. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma and melanoma. Melanoma is not as common as the other two but is much more aggressive and can be fatal if not caught early.
The American Cancer Society reports that more than two million people are diagnosed with non-melanoma skin cancer each year, and about 70,000 are diagnosed with the more serious melanoma. Since the best way to prevent skin cancer is early detection, get familiar with the location, size and color of any moles on your body and be aware of any new or changing moles.
Recognizing Suspicious Moles
Abnormal moles, also known as dysplastic nevi, can develop into melanoma over time. Have your moles checked annually by a dermatologist, or by a doctor during an annual exam. Get in the habit of performing monthly self-exams by standing in front of a full-length mirror with a hand held mirror to check hard-to-see areas. Start at the head and scalp and slowly work your way all the way down to your toes. Note any moles that have changed in size or color, are itchy, bleeding or oozing discharge and have them examined by a dermatologist as soon as possible to determine if they should be removed.
When it comes to moles, learn your ABCDs
When checking your skin for any new moles or changes in existing ones, use the following as a guide to recognize signs of a suspicious mole:
Asymmetry one half of the mole looks different from the other half
Borders edges appear notched, uneven or blurred
Color the color is uneven with varying shades of brown, tan and black
Diameter the mole is larger than 6mm, or the size of a pencil eraser
When should a mole be removed?
If you or your doctor notice any suspicious moles, the doctor will decide if the mole should be removed. Most moles are removed easily during a doctors office visit and might require a few stitches to close the area. Since most atypical moles are hereditary, everyone with a family history of melanoma should be vigilant about checking their moles frequently.
Most skin cancers are curable when detected and treated early. To learn more about the different types of skin cancer or to find a dermatologist anywhere in the U.S., download the free health app iTriage for your mobile device from the iTunes store or Android Market, or visit their website at www.iTriageHealth.com.
RTDs (resistance temperature detectors) are one of the most common temperature sensor types used in industrial applications. Thermocouples and thermistors are popular temperature sensors as well, but RTD sensors are more accurate over a wide temperature range and more stable over time, making them an excellent choice for many applications.
An RTD sensor is essentially a resistor whose resistance value increases with temperature. Due to the predictable change in resistance of certain materials as temperature changes, it is possible to acquire highly accurate and consistent temperature measurements. Most RTD sensors have a response time between 0.5 to 5 seconds or more. RTD sensors can be constructed with pure platinum, nickel or copper. RTDs made with platinum are also known as PRTs (platinum resistance thermometer) and are the most frequently used given their higher temperature capabilities, stability and repeatability.
Specifications for RTD sensors include a base resistance value and a temperature coefficient of resistance (TCR) value. Typical base resistance values can range from 10 to several thousands of Ohms () depending on material and type. The base resistance value indicates the nominal resistance of the sensor at 0C (nickel and platinum) or 25C (copper), with 100 being the most common.
The temperature coefficient of resistance does not affect a sensor’s accuracy, but is important to the measuring device that calculates changes in temperature based on the base resistance. PRTs have two standards of TCRs; the European standard (IEC 751) requires a TCR of 0.00385//C; and the American standard requires a TCR of 0.00392//C. Assuming a TCR of 0.00385//C meaning that for every degree change in temperature, the resistance increases by 0.385 a 100 PRT’s resistance will be 138.5 at 100C. Likewise, assuming a TCR of 0.00392 //C will result in a resistance of 139.2 at 100C. Thus, the measuring device used needs to be attuned to the TCR of an RTD sensor in order to accurately report changes in temperature, but the difference in TCR value has no impact on the sensor itself.
Thermocouples and thermistors are some of the other popular temperature sensors used in industrial applications. Thermocouples basically convert thermal energy into electrical energy, and use that to measure the temperature. While thermocouples measure the highest temperatures, respond quickly to temperature changeswithin fractions of a secondand are easily obtainable at low cost, they are the least stable and repeatable, and suffer from poor accuracy. Thermistors are semiconductors that present a non-linear change in resistance as temperature changes; unlike an RTD, the resistance in a thermistor decreases as temperature increases. In comparison, thermistors feature high sensitivity to small temperature changes and become more stable with use, but are fragile, have a limited temperature range and currently lack standardization.
Between the three types of temperature sensors, RTD sensors are the most accurate and stable over time, and are resistant to contamination under 660C. They also boast high repeatability, which means that RTDs can accurately measure identical temperatures even when exposed to repeated heating and cooling cycles with minimal discrepancies. This means that an RTD sensor will consistently measure 100C after being put into an oven and subsequently a freezer multiple times. In contrast, a thermocouple is more likely to measure 100C, then 98C, then 103C and so on when placed in the same situation. Since most applications do not require immediate responses (less than 0.5 to 5 seconds) to temperature changes, RTDs are an ideal solution for many industrial applications, which Network Technologies Inc (NTI) includes in its product line of ENVIROMUX Enterprise Environment Monitoring Systems and Accessories.
NTI offers a line of platinum 100 RTD sensors that can be used in conjunction with one of three available transmitters to accurately monitor temperatures in many industrial applications. The temperature ranges of the available RTDs are: -67 to 240F (-55 to 115C), accurate to within 0.27F (0.15C); 35F to 140F (2C to 60C), accurate to within 0.6F (0.33C); and -30F to 230F (-34C to 110C), accurate to within 0.6F (0.33C). Rugged, waterproof RTD sensors are available for harsh environments. Some of the common installations for the RTD sensors include: plenum mounting, duct mounting, immersion wells, direct mounting onto sheet metal duct systems, remote temperature sensing for building automation systems and mechanical equipment room instrumentation.
Transmitters are necessary to convert the resistor values into temperature values, and can be connected to NTI’s Enterprise Environment Monitoring Systems for a variety of alert and logging functions. The ENVIROMUX-RTDT-x 100 Platinum RTD Transmitter is available in two ranges, -20 to 140F (-28 to 60C) and 30 to 240F (-1 to 115C), and is accurate to within 0.8F (0.45C). Both units support 2-wire connections and can be calibrated for higher accuracy. With a wider temperature range of -328 to 1562F (-200 to 850C), the ENVIROMUX-RTDT-1562 High-Accuracy Platinum RTD Transmitter is accurate to within 0.2F (0.1C). It supports 2, 3, or 4-wire connections and is configurable to support 100 platinum, 120 nickel or 10 copper RTD sensors. With RS485 signal output, the transmitter boasts precise temperature measurements.
When combining the RTD sensors and transmitters with NTI’s ENVIROMUX Enterprise Environment Monitoring Systems, companies not only can accurately monitor temperature, but they also can monitor a wide range of other environmental threats such as humidity, liquid water presence, power, intrusion and smoke, and receive alert notifications when a sensor goes out of a configurable threshold an ideal preventive measure for many industrial applications.

For the past decade, most of us have spent more and more of our workday in front of a computer. Handling email, writing documents or on the web, whatever the time of day we can be found typing into our PCs or smartphones.
If we’re going to spend hours every day at a screen, there are things we can do to make that time more effective. But first, let’s work out what we’re actually doing. Keep a PC activity log every day for a typical week.
Do this with a pencil and paper, just write down when every task begins and ends, or use an automated time tracking application like Qlockwork for Windows (http://www.qlockwork.com) to do it for you.
Look at the log. There are the 3 simple ways PC time can be used more effectively.
1. Delegate or drop
We all spend time on computer tasks we don’t really need to do. For each regular task, would the world end if we didn’t do it? If the world would indeed end, could we delegate or outsource it?
We know delegation is a powerful tool. It can be painful up front but if we start delegating more of our responsibilities it can be the most effective way to free up time.
2. Don’t let email drive you
Don’t run your inbox or let your inbox run you. Email is a reactive task, not one that generally helps us achieve longterm goals.
Turn off email arrival notifiers. No more sounds. No more pop-ups. Review email at set times of the day like first & last thing. Don’t prioritize email above everything else and complete a genuinely important task before opening your inbox. Good email clients like Microsoft Outlook will let you turn your notifiers off.
3. Avoid interruptions
Stopping and starting on tasks is more destructive than we think. Studies show that jobs can take 30% longer if they aren’t finished in one go. When we pick a task up, ideally we shouldn’t put it down until it’s finished.
Easier said? Email is a great replacement for phone calls because emails don’t have to interrupt you. Unfortunately, we often let them interrupt anyway. Turn off notifiers and only review emails at set times.
Got an office door? Close it sometimes and unplug the internet connection or even work at home for some tasks if there are fewer distractions there. There are times when this won’t be possible but we should look for times when it is.
To summarize, if we want more hours in the day we need track our time and find out where it goes. Delegate or drop, control emails, give ourselves quality time to focus on key responsibilities. That should mean PC time is better spent.
Android is the most widely used OS that is running on many of the greatest cell phone deals. All people wants to get Android phones given that they offer plenty of advantages. Even if it is very high-quality the Android software has some issues that can prove quite frustrating.
The most sensible thing about Android is that is an open software. It lets customers develop new apps that can run on this OS. You can find not many software package that can permit you to do this. This is a real opportunity for those that produce apps. The Android is bringing out a new trend in the marketplace. All the people who choose one of the cell phone deals in the marketplace want to have accessibility to all the programs that can improve the way their machine works. It is true that this applications can prove a protection glitch. Many poor consumers try to make malware software and try to steal your data from your cellphone. This is a big problem for everyone Android running phones. They have safety issues that until now haven’t recently been solved. It is correct that there are a lot of initiatives put in developing sturdy safety software packages.
The Android is extremely good as it is up-to-date really usually. There are small improvements each day that correct a number of errors or open doors in the computer software. It is very important to update the software program on your phone regularly. Using this method you will see that the phone works well and it does not freeze or block. The major downside of this is that you may need a good web connection. Mobile internet connections are pretty expensive and many individuals can not afford to buy a subscription to a mobile phone internet provider. Without the internet connection you cannot update your software and you will remain a potential victim of hacking.
Although the Android has a lot of difficulties with security, it continues to be one of the favorite devices on the market because it has a nice design and it is really friendly to its users. Also, people prefer it because they are really used to all the Google merchandise and they are very open towards new applications made and developed by the company. I am a fan of Google too and I must say that I like the Android software. I am aware of the risks but the OS is extremely good and I like it as it is.
