Abstract: A mobile communications device includes a plurality of first input devices capable of passively collecting input data, a second input device(s) capable of collecting response data based upon a challenge, and a processor capable of determining a level of assurance (LOA) that possession of the mobile communications device has not changed based upon a statistical behavioral model and the passively received input data, and comparing the LOA with a security threshold. When the LOA is above the security threshold, the processor may be capable of performing a given mobile device operation without requiring response data from the second input device(s). When the LOA falls below the security threshold, the processor may be capable of generating the challenge, performing the given mobile device operation responsive to valid response data, and adding recent input data to the statistical behavioral model responsive to receipt of the valid response data.

Abstract: Methods and devices are provided for monitoring a battery to determine whether sufficient battery power remains to perform an event at a pre-scheduled time. A communications device includes a processor that receives instructions to perform the event at the pre-scheduled time, determines a first amount of time until the event is performed, detects an idle mode of the communications device, the idle mode consuming a minimum amount of power, calculates a second amount of time until the battery is depleted, the second amount of time being calculated while the communications device operates in the idle mode, determines whether the second amount of time is less than the first amount of time, activates a first alert if the second amount of time is less than the first amount of time while remaining in the idle mode, and performs an action prior to the pre-scheduled time while remaining in the idle mode.

Abstract: The present disclosure provides a method, system and stylus for drawing tool selection. One or more drawing tool settings, each defined by user-selectable drawing tool attributes, are formed by user interaction with a user interface. A user-activated control on a stylus signals a host electronic device to select a drawing tool setting. The settings may be selected in cyclic order. When a selected drawing tool setting includes color, the host electronic device may signal the selected color to the stylus for display using a color indicator on the stylus.

Abstract: The present disclosure provides for electronic drawing using a virtual ruler. An image rendered on a display of an electronic device executing a drawing application in response to stylus input is bounded by an edge of a virtual ruler. The virtual ruler is rendered in a region of the display in response to user input, the region being bounded by an edge of the virtual ruler. In response to a received stylus gesture, a line is rendered on the display outside of the region bounded by the edge of the virtual ruler. Stylus input inside the region may be ignored or auto-corrected to the edge of the ruler. Stylus input outside of the region may be auto-corrected to the edge of the virtual ruler or used without correction.
