We may not see all of these Apple patents implemented on the iPad 2, but they are interesting nonetheless. Several patents filed by Apple engineers have surfaced in recent days. One modification to the back of the iPad could put some accessory manufacturers out of business.

The diagrams show a built-in stand on the back of the tablet computer that would fold out to provide a comfortable tabletop viewing angle. A dual hinge would allow the iPad to rest on the kickstand in either landscape or portrait position.

We've been awaiting the arrival of the modulR case system since we first featured it back in late March. modulR is an innovative case system that allows a single iPad case to be used with a variety of accessories to achieve a number of different functions. Coupled with its accessories, the modulR case can function as an iPad stand, an iPad wall mount, an iPad swivel arm mount, and an iPad car mount (though the accessory providing the latter two features aren't yet available).

modulR arrived in our offices late last week, and a busy weekend prevented us from getting a first look until this morning. That said, we got to spend a bit of time with the modulR case, the modulR Quick Stand, and the modulR Slim Mount this morning. We've put together a quick first look for those of you who also have had your interest piqued by the modulR system.

The Luxa2 H4 iPad stand just looks cool. With its arms and and aluminum body, it looks like serious hardware. And, at a MSRP of $59.99, reasonably priced for a professional grade stand. There is a matching Luxa2 H1 stand for the iPhone. (There is also an H2 stand for the iPhone that does not have the arms - it relies on a tacky back to hold your phone in place. YMMV in its use, but I would recommend the H2 and keep the arms.)

The iPad Frame Dock is made of real wood and a stainless steel inner frame to give your iPad that classic, framed look when displaying photos. The frame is available in several different color combinations, including stainless dark brown, stainless black, standard light brown, standard dark brown, and standard natural. Standard natural allows the user to stain or paint a custom color on the iPad frame. The iPad Frame Dock runs $49.95.
