Abstract: The disclosure is directed to a device interface, system and method for connecting a Tester Interface Unit (TIU) to an automated test equipment that enable data rates of over 1.0 Gbps over scalable high speed cables. The device interface includes at least one flange assembly connecting an electron beam probe (EBP) in a vacuum-controlled environment to an ambient environment, the flange assembly including a vacuum-controlled passthrough environment coupled to the EBP, a plurality of cables coupled to a plurality of connectors within the vacuum-controlled passthrough environment to provide power, control and signal connections to the ambient environment, the plurality cables including plurality of hermetically-sealed printed circuit boards (PCBs) carrying digital high speed signals from the TIU, a plurality of power cables supporting a plurality of power requirements, and a plurality of ATE communication control cables to direct the TIU.

Abstract: Wind buffet noise in a microphone signal is detected using a per-frequency probability of speech estimate as well as short-term and long-term low-frequency energy. Using the probability of speech presence estimate, the buffet-no-speech condition can be accurately detected. But the probability of speech presence, by itself, is insufficient for distinguishing between the buffet-speech and either of the no-buffet conditions. It can be assumed that, if wind buffeting is occurring, it is occurring during both speech and non-speech segments to help distinguish between the other possible states. That is, the probability difference may be used as the criteria for entering the buffet-no-speech state, and then some other information (e.g., low frequency energy) may be used to determine when to transition to the buffet-speech state or one of the no-buffet states once the probability difference criteria is no longer met.
