A portable housing supports a processor coupled to memory for storing medical firmware and wireless radio firmware, first and second radios, a processor, and a power source. Communications are effected between an implantable medical device and the first radio in accordance with program instructions of the medical firmware, and between the second radio and the wireless network in accordance with program instructions of the wireless radio firmware. The first and second radios are configured to operate cooperatively in a first testing configuration, by which the first radio operates as a transmitter and the second radio operates as a receiver, and cooperatively in a second testing configuration, by which the second radio operates as a transmitter and the first radio operates as a receiver. Functional testing of the first and second radios is implemented using one or both of the first and second testing configurations.

Wireless patient communicator for use in a life critical network

A system including a communication circuit and a microprocessor operable to execute instruction code associated with at least a first operating system and a second operating system. The system also includes a volatile system memory to store executable code, a nonvolatile memory to store executable startup code, and nonvolatile image storage to store at least one captured state image. The captured state image includes an image of system memory in a captured state associated with a non-executing operating system. The system further includes a system transition routine to transition between the executing operating system and the non-executing operating system when an application to be run on the microprocessor requires the non-executing operating system. The system transition routine converts content of volatile memory and microprocessor registers to a captured state in accordance with the non-executing operating system captured state image stored in the nonvolatile image storage.
