In the String Formatting article, you saw how you can use the StringFormat property of a data binding to convert any type into a string. For other types of conversions, you need to write some specialized code in a class that implements the IValueConverter interface. (The Universal Windows Platform contains a similar class named IValueConverter in the Windows.UI.Xaml.Data namespace, but this IValueConverter is in the Xamarin.Forms namespace.) Classes that implement IValueConverter are called value converters, but they are also often referred to as binding converters or binding value converters.

The Enable Buttons page in the Data Binding Demos sample demonstrates how to use this value converter in a data binding. The IntToBoolConverter is instantiated in the page's resource dictionary. It is then referenced with a StaticResource markup extension to set the Converter property in two data bindings. It is very common to share data converters among multiple data bindings on the page:

Some value converters are written specifically for particular applications, while others are generalized. If you know that a value converter will only be used in OneWay bindings, then the ConvertBack method can simply return null.

You can write value converters to be more generalized and to accept several different types of data. The Convert and ConvertBack methods can use the as or is operators with the value parameter, or can call GetType on that parameter to determine its type, and then do something appropriate. The expected type of each method's return value is given by the targetType parameter. Sometimes, value converters are used with data bindings of different target types; the value converter can use the targetType argument to perform a conversion for the correct type.

The Switch Indicators page demonstrates how it can be used to display the value of a Switch view. Although it's common to instantiate value converters as resources in a resource dictionary, this page demonstrates an alternative: Each value converter is instantiated between Binding.Converter property-element tags. The x:TypeArguments indicates the generic argument, and TrueObject and FalseObject are both set to objects of that type:

I did. The listing still ended and found a buyer. i dont feel like anything was done about it. I noticed multiped other listings for used catalytic converters being sold. This is why I started to wonder if this was allowed or they were somehow going unnoticed. I couldn't find a clear policy regarding ebay's policy.

The California Air Resources Board, with assistance from aftermarket catalytic converter manufacturers, has been developing a database to store and retrieve information on aftermarket catalytic converters that have been approved for use in California. These catalytic converters comply with the new regulations that became effective January 1, 2009. The database is currently under construction and contains some of the catalytic converters approved for OBD II vehicles. Once finalized, it will also include catalytic converters for non-OBD II vehicles.

For information on Executive Orders issued under the old regulations, view the summary list. All Executive Orders on this summary list are void and no longer in force and effect. The catalytic converters they cover cannot be sold in California effective December 31, 2008. Likewise, the used catalytic converters they covered cannot be sold in California effective July 10, 2008.

Please note that the database and lists are applicable to passenger cars, light-duty trucks, and medium-duty vehicles only. Executive Orders for motorcycle aftermarket catalytic converters can be viewed in the Motorcycle Aftermarket Parts Page.

Today we're diving in to the often debated & sometimes mysterious topic of single disc vs. multi disc lock-up torque converters for use in common OEM-based overdrive transmissions. To begin, we need to understand the purpose of a torque...

We keep about eight pairs of VDSL media converters in stock and use them in last-mile scenarios. They are used where we need very high bandwidth over standard copper wire and can provide 80MB bandwidth in both directions. Not many people are aware of them, but the speed you get out of these devices is fantastic.

Our electric converters and machines are designed specifically for use in mobile work machines, commercial vehicles, and marine vessels to withstand harsh environments such as high temperatures, vibration, and shock ranges. Our portfolio also includes electric systems optimized for mobile elevating work platform (MEWP) and off-highway applications.

The converter acts as the link or the transforming stage between the power source and the power supply output. There are several kings of converters based on the source input voltage and the output voltage and these falls into four categories namely the AC to DC converter known as the rectifier, the AC to AC clycloconverter or frequency changer, the DC to DC voltage or current converter, and the DC to AC inverter.

There three basic converter circuits that are widely used in DC to DC converters are the buck, boost, and the buck and boost. These configurations are the most used topologies due to their simplicity and use of fewer components. Each has its advantages and drawbacks which determines the suitability for any specific application.

They are based on the non-isolated topologies but with the inclusion of a transformer. The commonly used types are, the full bridge, the half bridge, forward and the push pull converters, which are the isolated versions of the buck; and the flyback which is the isolated version of the buck-boost converter.

Converters are widely used in the electronic equipment, in power supplies and other circuits requiring specific voltage and current levels other than the available raw supply energy. The converters provide any type of the required voltage at the desired magnitude. With a proper design and use of the almost ideal components, the available methods of conversion offer variety of reliable and efficient energy to power most of the electronic devices and components.

A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves.

The first widespread introduction of catalytic converters was in the United States automobile market. To comply with the U.S. Environmental Protection Agency's stricter regulation of exhaust emissions, most gasoline-powered vehicles starting with the 1975 model year are equipped with catalytic converters.[1][2][3] These "two-way" converters combine oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) to produce carbon dioxide (CO2) and water (H2O). Although two-way converters on gasoline engines were rendered obsolete in 1981 by "three-way" converters that also reduce oxides of nitrogen (.mw-parser-output .template-chem2-su{display:inline-block;font-size:80%;line-height:1;vertical-align:-0.35em}.mw-parser-output .template-chem2-su>span{display:block;text-align:left}.mw-parser-output sub.template-chem2-sub{font-size:80%;vertical-align:-0.35em}.mw-parser-output sup.template-chem2-sup{font-size:80%;vertical-align:0.65em}NOx);[4] they are still used on lean-burn engines to oxidize particulate matter and hydrocarbon emissions (including diesel engines, which typically use lean combustion), as three-way-converters require fuel-rich or stoichiometric combustion to successfully reduce NOx. 0852c4b9a8
