Sharing memory resources of wireless portable electronic devices
View Patent ↗It is not uncommon for two or more wireless-enabled devices to spend most of their time in close proximity to one another. For example, a person may routinely carry a personal digital assistant (PDA) and a portable digital audio/video player, or a cellphone and a PDA, or a smartphone and a gaming device. When it is desirable to increase the memory storage capacity of a first such device, it may be possible to use memory on one or more of the other devices to temporarily store data from the first device.
1. A method to manage data storage of a first wireless portable electronic device, the method comprising:
identifying a calendar appointment, stored in a memory of the first wireless portable electronic device, that is scheduled to occur on a future date that is more than a predetermined time in the future; and
in response to identifying the calendar appointment:
securely transmitting the calendar appointment over a wireless communication link to a second wireless portable electronic device that is within range of the first wireless portable electronic device;
writing in the memory information used to retrieve the calendar appointment from the second wireless portable electronic device;
erasing from the memory the calendar appointment that was transmitted to the second wireless portable electronic device; and
as the future date approaches and is no longer more than the predetermined time in the future, automatically retrieving the calendar appointment from the second wireless portable electronic device and storing the calendar appointment in the memory of the first wireless portable electronic device.
