Abstract: Methods and systems are provided for managing electrical power consumption in a mobile phone or other portable communications device having a battery and a display. A series of views forming a flow are retrieved from a memory or other digital storage device for presentation on the display. For each of the views in the flow, performance information relating to the portable communications device is determined while the view is displayed, and this information is stored in the digital storage medium. Upon subsequent retrieval of each view from the digital storage medium, configuring the operation of the portable communications device in response to the stored performance information to thereby manage the electrical power consumption of the portable communications device.

Abstract: Embodiments of the systems and methods utilize application contexts for extending virtual machines in a resource-constrained device to allow virtual machines to at least exercise scheduling control over platform independent applications and platform dependent native applications. Application contexts can be assigned to each application in the system. An application is represented by one or more data structures and functions. In one embodiment, an “application context” includes an interface to a virtual machine and a container for an execution environment of the application. The interface represents a mapping of services to an execution environment. The application context can isolate control over the execution of the application from the execution environment, thus, allowing the virtual machine to control execution of the application and allowing the application to be executed in a native environment, a virtual machine environment, or any other execution environment.

Abstract: Layers of overburden are progressively removed from one inclined side of a cut by a rotating cutter and deposited on the other side of the cut in substantially the same geological sequence by traversing the cutter along an arm sloping along the inclined side, conveying the removed overburden by the arm to the bottom of the cut, and depositing the overburden by an adjustable endless belt on the opposite sloping side. The arm is moved along the sloping side by self-propelled transport units at the top and bottom of that sloping side.
