First Claim
1. An electronic system, comprising:
- a mother printed circuit board;
at least one peripheral printed circuit board physically and electrically hardwired to the mother printed circuit board by a hardwired connection defined a system bus, the system bus also connected to a processor; and
a wireless communications system comprising a first wireless communications device coupled to the mother printed circuit board and at least one second wireless communications device coupled to the at least one peripheral printed circuit board, where the first wireless communications device and the at least one second wireless communications device are coupled for wireless communication with one another via a wireless connection.

Abstract
A method and apparatus for providing redundancy, diagnostics, and authentication for hardwired circuit boards in an electronic device. The method and apparatus include a first printed circuit board and at least one second circuit board physically and electrically hardwired to the first printed circuit board. A wireless communications system comprising a first transceiver coupled to the first printed board and at least one second transceiver is respectively coupled to the at least one second printed circuit board. The first transceiver communicates with each of the at least one second transceivers via a respective wireless communications path, such that each wireless communications path runs parallel with at least one hardwired signal path between the first printed circuit board and the at least one second circuit boards.

12. A method of providing a redundant wireless communications signal path in an electronic system comprising a first printed circuit board, at least one second printed circuit board hardwired to the first printed circuit board via a system bus, and a wireless communications system having a first wireless communications device coupled to the first printed circuit board and at last one second wireless communications device coupled to the least one second print circuit board, the method comprising:
-
detecting a fault along at least one hardwired signal path between the first printed circuit board and the least one second printed circuit board; and
establishing a wireless communications path between the first wireless communications device and the at least one wireless communications device, whereby the wireless communications path is an alternative communications path for the at least one hardwired signal path. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method of providing a redundant wireless communications signal path in an electronic system comprising a first printed circuit board, at least one second printed circuit board hardwired to the first printed circuit board, and a wireless communications system having a first wireless communications device coupled to the first printed circuit board and at least one second wireless communications device coupled to the least one second printed circuit board, the method comprising:
-
transmitting authentication codes from the at least one second transceiver to the first transceiver, wherein the authentication codes provide identification of the at least one second printed circuit board;
verifying the authentication codes from the at least one second printed circuit board;
sending an acceptance signal where the authentication codes match;
detecting a fault along at least one hardwired signal path between the first printed circuit board and the least one second printed circuit board; and
establishing a wireless communications path between the first wireless communications device and the at least one wireless communications device, whereby the wireless communications path is an alternative communications path for the at least one hardwired signal path.
