Abstract: In implementations of creating a communication group, a mobile device can receive a selection to enable communication of location information between devices that correspond to entities from a group of entities associated with a user of the mobile device. The mobile device can receive location information that describes a physical location or proximity of the devices that correspond to the entities, and present in a user interface on a display device, a visual representation that indicates at least one of the entities is at a location within a pre-set distance of the mobile device. A communication group can be created that includes the entities selected from the group of entities associated with the user of the mobile device. The mobile device can also communicate the location information of the mobile device to all of the devices that correspond to the entities as a group communication based on the communication group.

Abstract: This document describes tools capable of enabling users of mobile communication devices to create communication groups quickly and easily. With such a communication group a user may call, text, or instant message all persons in the group at once by selecting the communication group rather than each person in the group. In one embodiment, the tools enable a user to build a communication group by dragging and dropping indicators for persons he or she knows from one area of a screen into another area. In another embodiment, the tools automatically collect persons from those that the user knows based on one or more criteria. The user may then easily create a communication group of those collected persons, such as by tapping on an area of a mobile device's display.

Abstract: Systems and methods that intelligently download media files from a repository to a portable device of a user (e.g., cell phone), via an intelligent download engine and based on likelihood that such downloaded files are of interest to the user. Accordingly, from a user's perspective a seamless access to music depository is provided (e.g., typically all files of the depository seem to be virtually present on the portable device), and a user's manual interaction (e.g., selection of files based on memory requirement of the portable unit) is mitigated.

Abstract: An I/O port locking computer security system is implemented in the power management module of the hardware-software interface program (BIOS). A hotkey sequence of keystrokes activates the portlock feature and a system management interrupt signal (SMI) is generated. A SMI handler routine receives the interrupt signal and generates a signal to a hardware device handler. The device handler receives the signal and then disables various data transfer I/O ports on the computer (e.g., serial, parallel, fax, modem, floppy drives, and infrared communication ports). I/O ports in the disabled state cannot be accessed. Thus, data in the computer cannot be transmitted, copied, or "beamed" via infrared, to an unauthorized system or medium. I/O ports in the disabled state are enabled after receiving a password and a SMI interrupt signal is generated. A SMI handler receives the interrupt signal and generates a signal to a hardware device handler.
