1. glutting = overrunning [= overflow = переполнение]:
Пример:
"Gluts and starves are very important in debugging video connection problems. They count instances of the MVIP connection network receive message underunning (starving) or overrunning (glutting)"

2. OVD = Output Voter Diagnostic

Пример 2А:
"Digital output modules use output voter diagnostics (OVD). Under system control, each output point is commanded sequentially to both the energized and de-energized states. The forced state is maintained until the value is detected by the system or a time-out occurs (500 microseconds, typical case; 2 milliseconds, worst case). Using the integral OVD capability, each point can be independently verified for its ability to a transition to either state. The OVD is executed in TMR mode, thus assuring nearly 100 percent fault coverage and fail-safe operation under all single-fault scenarios."

Пример 2Б:
"Each type of Digital Output Module executes a particular Output Voter Diagnostic (OVD) for every point. Loop-back on the module allows each microprocessor to read the output value for the point to determine whether a latent fault exists within the output circuit. Dual Digital Output Modules provide a single series path, with the 2oo3 voting process applied individually to each switch"
