Abstract: A software and/or hardware to monitor system usage including how long system ran on a battery or with an AC adapter. The software and/or hardware judges whether fast charging is needed and/or how much charge is needed, and optimizes battery charging settings.

Abstract: The present disclosure pertains to stylus' for electronic devices, and in particular, to passive stylus' with multi-faceted functionality. A passive stylus has a first end and a second end wherein at the first end, a first nib is present, and at the second end, a second nib is present. The passive stylus may be suited to effect communication with a touch-input device adaptable to receive input from both ends of the stylus. The touch-input device contains code, when executed, to cause the device to initialize a touch application, receive an indication of touch data, identify a tip pattern from the received touch data, and execute a set of pre-determined instructions associated with the identified tip pattern. Furthermore, the touch-input device includes aprocessing unit communicatively coupled to memory. The memory includes code to identify a tip pattern from a set of known tip patterns associated with touch data.

Abstract: A method and system for sending an interrupt signal is described herein. The method may include detecting sensor data in a sensor controller and detecting a powered down port between the sensor controller and an operating system. The method may also include sending the interrupt signal from the sensor controller to the operating system. In addition, the method may include detecting the operating system has provided power to the powered down port. Furthermore, the method may include sending the sensor data from the sensor controller to the operating system.
