Part of the power-packed features that Apple will unveil via the new iPad 5 and iPad Mini 2 is the vibrate notification that alerts users on new messages or delivers feedbacks during intense game sessions.

In a new Apple patent unearthed by PatentlyApple, the upcoming iOS tablets will likely include a vibrate features that is similar to that of the iPhone and Android handsets.

If the new invention will make it to the rumoured iPad 5 and iPad Mini release later this year, the upcoming slates will be capable of silently alarming users when messages or game feedbacks come in.

Note that aside from iPhones and Android smartphones, the feature is already a mainstay on premium Android tablets like Samsung's Galaxy Note 10.1 and Galaxy Tab 2 7.0.

"Apple's invention generally relates to a multi-channel audio coder decoder (codec) integrated circuit chip that is capable of driving either a speaker and/or a vibrator simultaneously or a pair of speakers simultaneously, through the same output pins," PatentlyApple said on its report.

The new technology will employ "a variable signal generator and a control input to receive a selection signal. The selection signal determines whether the channel is to be used for an audio signal or whether it is to be used for a vibrator signal," the same report added.

This could be a bit late addition for the next-generation iPad but is welcome for Apple fanboys who expect the fresh tablets to be unleashed as early as April 2013, based on new projections aired by Rene Ritchie of iMore.

Yet with the emergence of more features that both the iPad Mini 2 and the iPad 5 will display, more experts are leaning to a late 2013 release for the iOS 7 tablets, possibly between the months of September and October.

The much-awaited new offerings of the iPad Mini 2 is its Retina display and higher specs while the iPad 5 is generating hyper-interest on talks that its body-design is taking a direct page from the first iPad Mini.

It should be a smaller, thinner, lighter but more powerful iPad. It will shed much of its heft while retaining the 9.7-inch screen size, reports said.
