Methods and apparatus for an improved signal monitor
First Claim
1. A signal monitor of the type configured to accept a plurality of input signals associated with traffic control at an intersection, said signal monitor comprising:
- an interactive display capable of providing a visual representation of;
a) monitor status information, wherein said monitor status information includes information relating to the status of at least a portion of said plurality of input signals;
b) diagnostic information, wherein said diagnostic information includes an indication of fault type, an indication of faulty input signals, and troubleshooting information associated with said fault type and faulty input signals, wherein said diagnostic information includes a textual interpretation of the results of a field check analysis performed on said input signals.

Abstract
A malfunction management unit (MMU) includes advanced diagnostic and set-up capabilities accessed through a display-based user interface. In general, the MMU is capable of displaying (1) monitor status information, wherein the monitor status information includes information relating to the status of at least a portion of the input signals; and (2) diagnostic information, wherein the diagnostic information includes an indication of fault type, and indication of faulty signals, and troubleshooting information associated with said fault type and relevant faulty signals. The diagnostic information includes a textual interpretation of the results of a field check analysis.
