Upcoming iOS devices, specifically the iPhone 6 and the iPhone 5S, are envisioned by Apple to better manage component temperature, produce excellent images and deliver precise touchscreen functions.

In the first invention, among the fresh set of patent applications discovered by Patently Apple this week, the tech giant is revealed working on handsets that are less prone to overheating.

This is due to a new technology that will use "an amorphous diamond-like carbon (DLC) coating for increasing the thermal conductivity of the structural frames of any Apple mobile device that is battery-powered," the report said.

Apple normally relies on efficient component design or parts placement on the device board in order to facilitate the distribution of heat inside an iPhone and avoid overheating. But with the new design scheme, a "DLC coating is deposited on the surfaces and the edges of the structural frame, which increases the thermal conductivity of the structural frame," the report said.

In one of the practical applications, the embodiment could come in a structural form that is made of the following composite materials: stainless steel, zinc, magnesium, aluminium, copper and glass-filled plastic, the report added.

In another patent, Apple hinted that future iPhone makes will be deployed with multi-touch capacitive touch sensor panels that "can be created using a substrate with column and row traces formed on separate layers of the substrate."

In essence, the new design aims "to reduce the effects of noise and thermal drift and to provide users with more precision in their interaction with a touch display," Patently Apple said on its report.

This invention further backs speculations that Apple is increasingly moving into the touchscreen sphere for its device control keys, thereby pointing to the gradual elimination of the physical keys.

The latest iPhone 6 concepts pointed to an Apple phablet that has a wrap-around display with disappearing control buttons. As for the iPhone 5S, it is widely believed that the handset is without a physical Home button on release date, replaced by capacitive key that is coated in sapphire.

The last patent in subject deals with illuminant estimation for the next-generation iPhone and iPad cameras, "in particular to a method of chromagenic illuminant estimation which concentrates on the brightest pixels," Patently Apple said.

The core benefit from the new camera feature is the elimination of "the colour biases from images due to the illumination."

With the feature, camera enthusiast and professionals alike will be able to produce top-quality pictures using only the iPhone 6 or the iPhone 5S.
