Apple sues HTC over two more patents: power conversing process, unlock gesture.
Apple has launched yet another scathing lawsuit against smartphone makers HTC for a second round of patent infringements, in Delaware District Court yesterday. The new lawsuit mentions four patents held by Apple: two of which were included in the previous lawsuit, and two which are new to this case. The patents are:
- Patent 7,383,453 (June 3, 2008): Conversing power by reducing voltage supplied to an instruction-processing portion of a processor.
- Patent 7,657, 849 (Feb 2, 2010): Unlocking a device by performing gestures on an unlock image.
- Patent 6,282,646 (August 28, 2001): System for real-time adaptation to changes in display configuration.
- Patent 7,380,116 (May 27, 2008): System for real-time adaptation to changes in display configuration (this is a continuation of the previous patent, hence the similar names)
Real-time display config adapta–What? Yeah, here is what it all means:
A hot-plugging capability for video devices is achieved by shifting the responsibility for recognizing changes in the configuration of a display environment from a computer’s operating system to a device manager.
When an input/output device is added to or removed from the computer system, an interrupt signal informs a device manager of the fact that a change in configuration has occurred. In response thereto, the device manager determines whether the changed component relates to the computer’s display function.
If so, the device manager makes a call to the computer’s display manager, to inform it of the fact that the display configuration has changed. In response to this call, the display manager reconfigures the display space for the computer system and notifies clients as appropriate, to accommodate display features associated with the added component.
With this change in the configuration of the display space, the added component becomes immediately available for use.
