Persistent display of priority information on a portable electronic device
First Claim
1. A method for displaying a prioritized item on a persistent display in response to a low-power determination, the method comprising:
- a processing unit of a programmable personal digital assistant device populating a prioritized data list comprising a plurality of screen image instances listed in an order prioritized as a function of inputs from a user list of items, clock data associated with the user list of items, and calendar data associated with the user list of items;
the processing unit querying a power subsystem of the personal digital assistant device to determine a level of battery power currently available for operating processes of the personal digital assistant device;
the processing unit determining a number of screen display changes effectible on a persistent display device in communication with the personal digital assistant device by the processing unit at the determined level of available battery power;
the processing unit comparing the determined number of screen display changes effectible on the persistent display device by the processing unit at the determined level of available battery power to a specified minimum threshold number of images; and
in response to a determination that the determined number of screen display changes effectible on the persistent display device at the determined level of available battery power is not more than the specified minimum threshold number of images;
the processing unit powering down a subsystem of the personal digital assistant device to conserve battery power, and automatically causing a highest prioritized image of the populated prioritized data list to be displayed on the persistent display device; and
wherein the persistent display device is a non-volatile electronic ink display that, after a loss of power to the persistent display device, relies on reflected light to continue to persistently display the highest prioritized image or a currently displayed image that is displayed on the persistent display device.

Abstract
Personal digital assistant devices are provided that query power subsystems to determine a level of battery power currently available for operating processes, and further determine a number of screen display changes that may be effected on a persistent display device at that determined level. If the determined number of screen display changes that may be effected at the determined level of available battery power fails to meet a specified minimum threshold number of images, the processing unit powers down subsystems of the personal digital assistant device and causes a highest listed image of a prioritized list of screen image instances to be displayed on the persistent display device, which persistently displays the image after a loss of power.

12. A personal digital assistant device system, comprising:
-
a processing unit in communication with a computer readable memory, a computer-readable hardware storage device and a persistent display device; wherein the processing unit, when executing program instructions stored on the computer-readable hardware storage device via the computer readable memory; populates a prioritized data list comprising a plurality of screen image instances listed in an order prioritized as a function of inputs from a user list of items, clock data associated with the user list of items, and calendar data associated with the user list of items; queries a power subsystem of the personal digital assistant device to determine a level of battery power currently available for operating processes of the personal digital assistant device; determines a number of screen display changes effectible on the persistent display device by the processing unit at the determined level of available battery power; compares the determined number of screen display changes effectible on the persistent display device by the processing unit at the determined level of available battery power to a specified minimum threshold number of images; and in response to a determination that the determined number of screen display changes effectible on the persistent display device at the determined level of available battery power is not more than the specified minimum threshold number of images, powers down a subsystem of the personal digital assistant device to conserve battery power, and automatically causes a highest prioritized image of the populated prioritized data list to be displayed on the persistent display device; and wherein the persistent display device is a non-volatile electronic ink display that, after a loss of power to the persistent display device, relies on reflected light to continue to persistently display the highest prioritized image or a currently displayed image that is displayed on the persistent display device. - View Dependent Claims (13, 14, 15, 16)

17. An article of manufacture, comprising:
-
a computer readable hardware storage device having computer readable program code embodied therewith, the computer readable program code comprising instructions that, when executed by a computer processing unit, cause the computer processing unit to; populate a prioritized data list comprising a plurality of screen image instances listed in an order prioritized as a function of inputs from a user list of items, clock data associated with the user list of items, and calendar data associated with the user list of items; query a power subsystem of a personal digital assistant device to determine a level of battery power currently available for operating processes of the personal digital assistant device; determine a number of screen display changes effectible on a persistent display device in communication with the personal digital assistant device by the processing unit at the determined level of available battery power; compare the determined number of screen display changes effectible on the persistent display device by the processing unit at the determined level of available battery power to a specified minimum threshold number of images; and in response to a determination that the determined number of screen display changes effectible on the persistent display device at the determined level of available battery power is not more than the specified minimum threshold number of images;
power down a subsystem of the personal digital assistant device to conserve battery power and automatically cause a highest prioritized image of the populated prioritized data list to be displayed on the persistent display device; andwherein the persistent display device is a non-volatile electronic ink display that, after a loss of power to the persistent display device, relies on reflected light to continue to persistently display the highest prioritized image or a currently displayed image that is displayed on the persistent display device. - View Dependent Claims (18, 19, 20)
