Abstract: An electronic device comprising an electronic paper display that displays a first set of data, and a second display that displays a portion of the first set of data displayed on the electronic paper display. Preferably, the second display is a Liquid Crystal Display and displays the portion of the first set of data in color, whereas the portion is displayed on the electronic paper display in monochrome.

Abstract: A system and process for controlling multiple displays from a single graphical stack. Frame data is written to a single virtual frame buffer from a single graphical stack. The frame data is subsequently displaced from the virtual frame buffer to a plurality of display buffers. In this manner, a plurality of displays are updated. The system and process can operate with displays with different display technologies, such as an electronic paper display and a Liquid Crystal Display (LCD).

Abstract: A method and computer-readable medium for a dual dialer state machine are provided. The state machine allows a Radio Interface Layer (RIL) to make decisions on whether to allow calls to be initiated or terminated depending upon the type of call (interconnect or dispatch). The RIL uses the state machine to coordinate the functions of an interconnect phone application and a dispatch phone application.

Abstract: Methods of and corresponding systems for assessing performance of a processor in a thread based system are discussed. One method comprises: registering with an operating system kernel as a coprocessor; capturing, responsive to the registering, thread events for the processor; managing memory allocation corresponding to a multiplicity of threads; monitoring thread activity for the multiplicity of threads; tracking thread run time and thread idle time based on the monitoring thread activity; and determining a performance level for the processor based on the thread activity.
