1. A method comprising:
- transmitting a universal serial bus (USB) token packet to a first module within a medical device via an internal bus within the medical device;
when the fast module has a data packet to transfer, receiving the data packet from the first module via the internal bus; and
transferring the data packet to a second module within the medical device via the internal bus using a USB protocol.

Abstract
In general, the invention facilitates improved inter-module communication within a medical device system, such as an automated external defibrillator (AED), by using a serial data interface based on the USB specification to transfer data between modules. As a result, data transmission rates may be improved significantly, thereby providing ample communication bandwidth for a variety of medical device applications. Further, the serial interconnect nature of the USB interface reduces the number of physical interconnects that are needed to support the interface, thereby reducing the design constraints on the medical device system.
