Reversible connector orientation detection circuitry, reversibly connectible devices having multiple device portions, and methods for determining a connection orientation of multiple device portions of a hardware device are provided herein. A hardware device can include a first device portion and a second device portion. A first resistor can be in a first side of the first device portion. A second resistor can be in a first side of the second device portion, and a third resistor can be in a second side of the second device portion. Connection of the first device portion to the second device portion in different orientations creates, through the resistors, different voltages that can be compared by a digital logic device to indicate orientation. The compared voltages are within either a low voltage range below a digital logic low threshold or a high voltage range above a digital logic high threshold.

Reversible connector orientation detection circuitry

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.
