When providing a field to input numbers, SmartPhones can be told to automatically display a number key pad when the field is selected, but specifying <TT><input type="number"></TT>. iOS devices may add commas and remove leading zeros. To further specify the precision of the input, add e.g. <TT>step="0.01"</TT>. To future proof, also add <TT>pattern="[0-9\.]*"</TT>. <TT>type="tel"</TT> will trigger help with entering a phone number.

http://motyar.blogspot.com/2011/09/handling-html5-application-cache-with.html
One unexpected problem with appcache is that if the web page changes on the server, that change will not be seen on the remote device unless the appcache itself is refreshed. On Chrome, you can manage the appcache at <A HREF="chrome://appcache-internals/">chrome://appcache-internals/</A>. Web apps can offer updates when the appcache changes on the server by inserting the following Javascript on the main page:
<PRE>
// on page load.
window.addEventListener('load', function(e) {
//Check if a new cache is available
window.applicationCache.addEventListener('updateready', function(e) {
if (window.applicationCache.status == window.applicationCache.UPDATEREADY) {
// Browser downloaded a new app cache.
// Swap it in and reload the page to get the new version.
window.applicationCache.swapCache();
if (confirm('A new version of this site is available. Load it?')) {
window.location.reload();
}
} else {
// Manifest didn't changed. Nothing new yet.
}
}, false);
}, false);
</PRE>
Note: To trigger the update, the .appcache file, not the .html page, must change. After changing the page, just edit a comment (perhaps include a datecode or version number?) in the .appcache file.

Timothy Henry[TH-yahoo-] Questions:
Hi, i'm really new to stepper motor and it's drivers, so i hope you could help me with choosing a PSU. My stepper motor is 12V 2A/phase. In this site, it is said that i need to use PSU that supply 4-10 volts more than the motor voltage, but since i can't find a PSU in that range, could i just use a 12V PSU, or if properly cooled, could i use a 24V PSU for the linistepper?<BR>
<BR>
Thanks for your help!
