Crib safety is extremely important, as it is the one area of the home where you want to feel comfortable leaving your baby unsupervised. When you lay your child down to sleep -- just before tucking yourself in for the night -- you need to be able to trust that he will be safe and sound all night long. Doing a thorough check of your crib to ensure it meets the federal guidelines for safety standards will do just that, so you and your little one can both have sweet dreams.
Pacifiers can help soothe a baby’s strong urge to suck when he needs some comforting and it’s not mealtime. According to The American Academy of Pediatrics (AAP), pacifiers may also help reduce the risk of Sudden Infant Death Syndrome (SIDS) if used at nap and bedtime. As your baby grows and develops, his pacifier needs change. At a certain point, his mouth will outgrow the smaller stage one pacifier and you will need to switch him to a bigger size.

A mechanical relay is actually only half mechanical, with the second half being electrical. A relay is a switch that uses a low-current power supply to control a high-current power supply. Relays are often used in automotive applications to control headlights, fuel pumps, starters and electric cooling fans, as these devices require a much higher current than a normal switch would be able to sustain under long term use without failing. Your relays will often be located within the engine or passenger compartment fuse box and occasionally behind the dash or center console.
If you own an LG dishwasher, you may experience an "LE" error code, which indicates a problem with the motor. Sometimes the cause is the motion hall sensor, which is attached to the motor and helps determine its speed and direction. If your LG dishwasher is no longer under warranty, you could incur repair costs to have it fixed by a professional. Fortunately, there’s a way to troubleshoot the hall sensor and replace it if needed instead of replacing the entire motor assembly.
Investing in a network switch might make a lot of sense when your computer network starts approaching double-digit numbers of connected devices or high-quality performance becomes a priority.

Both brands produce a wide range of products and comparing individual products to each other may help you find the right hardware solution.
If you are building your own concrete driveway, patio or support columns, you should use reinforcing steel bars, or rebars. These bars are imbedded in the concrete, and increase its ability to withstand tension. You can install rebar in your own home concrete construction projects without any special construction training, but you need to learn how to test the rebar installation to make sure it set properly within the concrete and is safe to use.
Ammeters, as a type of gauge, aren't the most common on automobiles today. Unlike the voltmeter, which measures the energy or "temperature" of electrical flow, an ammeter measures the amount of electrical flow. This means that the primary requirement for any ammeter is that it impedes that flow by almost nothing. So, testing an ammeter is really just a matter of finding out if it still has the internal electrical resistance that it should.
Radio and TV broadcast companies determine how far signals travel by calculating the antenna’s height above average terrain, or AAT, in units of meters. Generally, the taller the antenna, the farther signals go, though the broadcast companies must deal with trade-offs between better transmission coverage and greater construction costs. Tall objects in the antenna’s vicinity obstruct the signal’s transmission, making the height of the average terrain an important factor.

If you're not testing your website in multiple browsers, you could be limiting your site's traffic. Although Internet Explorer still accounts for most Web traffic, as of February 2012, its share is eroding as visitors use a wide variety of devices and browsers. The percentage of browsers you should test for development is dependent on the complexity of your code, but you would be wise to test your site in the most-used browsers and operating systems.
To take the best quality photos in any amount of light, do an ISO test on your Canon Rebel T2i digital SLR camera. ISO, or International Organization of Standards, is a standard measure of a camera sensor's light sensitivity. Each camera handles light slightly differently, so testing your camera's ISO feature gives you an idea of how to adjust the settings specific to your camera in different lighting situations.
Computer programmers can use mocking to test the behavior of objects in the real world through a virtual environment. In short, mocking requires you to replace the real object with simulated objects to determine how the real object will actually behave in certain situations. If you have several interacting objects, you can isolate the behavior of one object by creating mock versions of the other surrounding objects -- to determine how the item you're testing will behave in relation to them.
Checking the stator -- the stationary part of your outboard motor's generator -- requires a digital multimeter. Nearly all problems that are ascribed to the stator are the result of a simple loose connection in the boat's wiring harness or some missing insulation. If the trouble isn't with the wiring harness, it may be a short that grounds a lead on the stator. Once that's proven untrue, the diagnostic path leads away from the stator, perhaps to a short between the stator and the secondary coil-- the output side -- of the ignition coil, or a short between the coil…
As projector technology becomes more versatile and affordable, end users have started installing more and more of them. Applications ranging from sports bars to corporate telepresence suites to advanced home theaters pack multiple projectors into a small area. In many cases, they do not have additional wiring, using a single electrical circuit to drive multiple projectors. While this can work well, it also poses challenges.
When you open up an electronic device, you'll find an array of electrical components such as resistors, capacitors and diodes. When one of these components burns out, it's important to install a replacement with identical specifications to ensure that the device works properly. Failure to use the right type of resistor can result in insufficient power or circuit overload.
Testing a Mercruiser temperature gauge requires you to unplug the instrument cluster connector from the engine's wiring harness. The connector's pins are numbered from 1 to 10 and are arranged in clockwise order around the face of the connector. The No. 1 pin is to the right of the key and the No. 10 pin is inside the ring formed by the others. Testing the temperature gauge requires you insert the probe into the Nos. 1, 3 and 8 pins. Testing the temperature gauge is an excellent excuse to go boating.
The Maytag PYET44AYW is a member of the Maytag Performa Dryer series. The dryer’s door switch is a mechanism that denotes whether the door is open or shut. If the door switch determines that the door is open, the dryer will not be operational. However, if the dryer does start when the door is open, the dryer may have an electrical short. Conversely, if the door is closed and the dryer does not start, the door switch may be malfunctioning.
Ketone production relates to fat metabolism. If the cat's body can't use glucose, his liver will produce ketones by breaking down fat into fatty acids. After accumulating in the blood, ketones pass in the cat's urine. Testing for ketones in felines consists of a urinalysis, with the presence of large numbers of ketones often indicative of a serious veterinary condition. Ketosis is usually a sign of diabetes mellitus in the cat.

A floating stool test, or a fecal flotation test, fecal float, egg flotation or Fecalyzer test, is a veterinary in-house procedure that rules out intestinal parasites in household pets or livestock. All cats should be tested for parasites on a regular basis, even if the cat is on parasite preventative medication. Intestinal parasites may be fatal if untreated, and zoonotic parasites, such as roundworms and hookworms, infect humans and pets, alike.
Federal Communications Commission regulations state that ham radio operators in the United States may legally transmit only the minimum power necessary to carry out the desired communication. No ham station may transmit more than 1500 watts unless otherwise restricted. Two meters represents the most popular frequency range used by ham radio operators.
Whether your webcam is built in to your computer or it's an external device, you may have to do some tweaking to get the program you're using to recognize the camera and to record your images properly. While using an online Flash test may help you see that your webcam is working properly, the test itself can create the need for even more adjustment. Every setup and camera is slightly different, but there are several things you can check to see if you can get your webcam to stop being so dark.
Blind SQL injection is one of the most dangerous SQL exploits due to its simplicity. The attacker doesn't need to know anything about your SQL database to inject third-party code in your tables. Furthermore, nothing is known of the outcome of an operation. Testing for blind SQL injection vulnerabilities in your Web applications is a crucial task that prevents loss of data and sensitive information. Fortunately, you can use a simple URL to test for blinds in SQL.
BCD stands for binary-coded decimal. In the 1950s and 1960s, some of the earliest versions of modern computers used binary. While this may seem like an old-fashioned process, many modern computers still use a form of BCD. Often, this is in the slightly different form of "packed decimal." A BCD switch changes electronic or digital signals into the decimal output.
Older model Toyota 4Runners from the mid-1980s came in two models with two different head sizes, the 22r and the 22re. The main difference between the two types of engines is the fuel system. The 22r is a model that runs on a carburetor, while the 22re is a fuel injected model. The primary problem that do-it-yourselfers run into is getting the right head for the 22re model, but switching out the fuel system is a matter of getting the wiring right.
Chevrolet introduced the S-10 in 1982. The 2001 S-10 was available in nine sub-models equipped with one of two engines options. A 2.2-liter in-line four-cylinder engine was the base engine, producing 120-horsepower and 140 foot-pounds of torque. The more popular 4.3-liter V-6 was available as an option, producing 190-horsepower and 250 foot-pounds of torque. The straplike devices on each end of the tailgate are called tailgate cables. The cables can be replaced with minimal effort and some basic automotive tools.
Synchronous generators on AC circuits supply power with three phases. To connect such a circuit to the power grid you have to synchronize the three phases with the three phases of the power grid to avoid large compensating currents that may cause damage or trip circuit breakers. You first have to match the frequency of the two systems by changing the speed of the generator slightly. Changing the generator field voltage adjusts the voltage to match that of the grid. When the voltage differences between the AC circuit and the grid are close to zero for each phase, the systems…
Substation and electrical system design engineers place disconnect switches on the primary and secondary sides of each transformer. A correctly rated disconnect switch must be able to carry the rated current of the transformer, withstand the maximum possible short circuit current and interrupt the rated voltage of the transformer winding to which it is connected. These switches serve to isolate the transformer for maintenance, or to cut its voltage if it is not needed. To ensure the safety of technicians working on the transformer, each disconnect switch has a feature allowing the technician to lock it in the open position…
If you just bought a Samsung D600 cellphone, test it to ensure it works so that you can promptly return it if you find a problem. The D600 has several features that should be tested, such as the Web browser, call functionality and the ability to record video. Testing the phone's basic functions is not time-consuming and is relatively straightforward.
The central processing unit (CPU) of a computer controls the calculations and executes the commands of all the running programs on that computer. This means that the processor often juggles multiple programs at the same time. To run any program, much less multiple programs, the CPU needs to have certain information from a program so that program can function. This information, called the state, differs from program to program. When switching between programs, the CPU must implement changes between states of programs, called context switching.
A malfunctioning dishwasher thermostat will cause the dishwasher to not work properly and leave your dishes less than clean. In addition, a damaged thermostat will prevent the dishwasher from completing a full cycle. Before you consider replacing the thermostat, try a few tests to determine whether the problem really is with the thermostat and not some other malfunctioning part. For best results, consult your specific dishwasher’s owner’s manual for thermostat troubleshooting.
For almost any electronic circuit of non-trivial complexity, debugging is part of the building process. The circuit may have wiring mistakes, a component may be misconnected or the circuit design may have flaws. By asking a general set of questions, you can quickly isolate and solve problems to get the circuit working.
