Patent ID: 7529610

Claim:
A brake interface module for an electronic air brake (EAB) and/or a magnet valve comprising: a) a positive train control circuitry comprising: i) a first microcontroller with at least one input and at least one output; and ii) a second microcontroller with at least one input and at least one output, the second microcontroller operatively coupled to the first microcontroller; and iii) first combinational logic circuitry with at least a first input, a second input and an output, the first input operatively coupled to an output of the first microcontroller and the second input operatively coupled to an output of the second microcontroller; b) at least one spare input for operatively coupling the brake interface module to, and for receiving input from, external devices; c) second combinational logic circuitry with at least one input and at least one output, at least one input of the second combinational logic circuitry operatively coupled to the at least one spare input; c) a first power supply operatively coupled to the at least one output of the second combinational logic circuitry; and d) a second power supply operatively coupled to the at least one output of the second combinational logic circuitry, wherein the positive train control circuitry allows for switching between the first power supply and the second power supply to insure a correct voltage for proper operation of at least one of the EAB and magnet valve.
