Abstract: An implantable medical device (IMD) with internal processor is configured for diagnostic emulation using an external processor coupled to the internal processor through a high speed serial link. The native external processor parallel data and address bus content can be converted to a serial communications stream, sent into the device, converted back to parallel address and data bus formats, and used to drive the device in place of the internal processor. The serial communication allows use of a small number of contact pads, conductors, or feed-throughs, depending on the device. Some devices allow serialized communication through the feed-through typically used for electrical stimulation. The devices can be used to enhance diagnostic testing with capabilities such as faster testing and more realistic testing. The IMD can be a wide variety of implantable devices such as neuro stimulators, pace makers, defibrillators, drug delivery pumps, diagnostic recorders, cochlear implants, and the like.

The external processor is coupleable to the medical device to execute software involving medical device components with a bus switch coupled to the address bus, the data bus, and the internal processor. The bus switch has a bus switch external connector that when activated is configured to couple an external processor through the address bus external connection to the address bus and the external processor through the data bus external connector to the data bus.

Abstract: A GPS utilizing redundant GPS receivers having position and time mark outputs connected directly to a processing block so that the time marks from both GPS receivers are received by the processing block and, in the event a first of the GPS receivers output becomes unusable and the system uses a second of the redundant GPS receivers while periodically checking the first for reusability, no time will be lost in the validation of the new channel.

Abstract: The present invention is a system that is used on board an aircraft that receives data, examines the data, and directs the data to appropriate memory devices for future use. A plurality of receivers are coupled to a serial data bus for selectively receiving a sequence of data messages on the data bus. Each of the receivers includes a data register for storing one of the sequential flow of data messages. In turn the receiver provides a data ready signal so that a sequencer can selectively read the data messages from the receiver and either store them in one of a plurality of receivers, or discard the information.
