Abstract: In one embodiment, a method includes providing, to each of a number of client devices, at least part of a graphical user interface (GUI) corresponding to a virtual room. The virtual room contains a number of users. The method further includes providing, to each of the client devices, a first portion of the GUI identifying at least some of the users in the virtual room. The method further includes providing, to each of the client devices, a second portion of the GUI, where the second portion of the GUI displays: (1) one or more user interactions from one or more of the users in the virtual room; and (2) for each user interaction, an identification of each particular user who generated the that user interaction.

Abstract: A method and apparatus for providing automatic power switching in a portable external defibrillator is disclosed. The power supply switching circuit includes a plurality of power supply ports for receiving power sources such as batteries and external power sources. The power supply switching circuit works with both batteries that include monitoring devices (smart batteries) and batteries that do not include monitoring devices (dumb batteries). The power supply switching circuit also includes microprocessor controllable switches for selectively coupling the power supply ports to the output of the power supply switching circuit, and a microprocessor for controlling the switches and for monitoring the power supply ports. Resident in the microprocessor is a control program for controlling the switching and monitoring operations. The control program uses data received from the power sources to select the best available power source to be used as the output for the power supply switching circuit.
