Abstract: A touch screen computing device for generating visual feedback responsive to user input includes an electronic display operative to provide feedback responsive to user interaction with the touch screen, a digitizer system operative to receive input responsive to the user interaction and a host computer. The host computer includes an operating system, a display driver for communicating with the electronic display, a digitizer driver for communicating with the digitizer system, and a software module for establishing communication between the digitizer driver and the display driver while bypassing the operating system, wherein the software is operative to provide for generating primary visual feedback responsive to input from the digitizer system.

Abstract: The claimed subject matter discloses a system for measuring power consumption of an electrical appliance. The system comprises a sensing module for sensing physical phenomenon, located externally to the electrical appliance. The system further comprises a transmitter for transmitting information representing the physical phenomenon sensed by the sensing module and a power device. The physical phenomenon sensed by the sensing module provides indication on whether the electrical appliance is ON or OFF and whether the power consumption of the electrical appliance increased or decreased. In some cases, the indication is one or more scalars representing the sensed physical phenomena.
