Abstract: User activity on a mobile device is monitored and collected, and a resource usage model is constructed. The resource usage model describes a set of contexts in which the mobile device, and is the basis for determining a first exhaustion point for a resource. Based on the monitored activity, a prediction of a second exhaustion point for the resource time is made. If the second exhaustion point is prior to the first exhaustion point, usage of the resource is reduced.

Abstract: Security is enhanced for a user of an electronic device by providing a method for visually monitoring the progress of a security operation on an electronic device that provides a plurality of objects including at least one of an application, a document, a file, an image, and a record. When a security operation is launched for at least some of the plurality of objects, an operation window is displayed on the electronic device's display screen. The operation window includes a first operation icon corresponding to a first object on which the security operation is currently being performed. The first operation icon includes a thumbnail icon representing the first object and an operation completion indicator that visually indicates a completion level of the security operation currently being performed on the first object.

Abstract: Security is enhanced for a user of a mobile device by monitoring and controlling resource usage. Usage information associated with a mobile device is collected. The collected information is used to build a usage model for a user of the mobile device that describes a set of contexts in which the mobile device is used. User activity on the device is monitored and the model is consulted to determine a first time after which it will be acceptable for a battery of the mobile device to fall below a threshold charge level. Based on the monitored activity, a prediction of a second time is made for when the battery will fall below the threshold charge level. If the second time is before or a predetermined amount of time before the first time, usage of the battery is reduced, else, usage of the battery is not reduced.
