Abstract: A method of responding to an anomalous change in downhole pressure in a bore hole comprises detecting the anomalous change in downhole pressure, sending a signal along the segmented electromagnetic transmission path, receiving the signal, and performing a automated response. The anomalous change in downhole pressure is detected at a first location along a segmented electromagnetic transmission path, and the segmented electromagnetic transmission path is integrated into the tool string. The signal is received by at least one receiver in communication with the segmented electromagnetic transmission path. The automated response is performed along the tool string. Disclosed is an apparatus for responding to an anomalous change in downhole pressure in a downhole tool string, comprising a segmented electromagnetic transmission path connecting one or more receivers and at least one pressure sensor.

Abstract: A keyboard assembly comprises a housing structure and an air circulator apparatus attached to the housing structure. The housing structure has an interior space therein, a key opening within a housing wall thereof and at least one key movably extending through the key opening whereby a gap is provided between the key opening and the at least one key. The air circulator apparatus includes an air circulation device having an air inlet portion and an air outlet portion. The air inlet portion receives substantially an entire portion of air circulated by the air circulation device from outside of the housing structure and the air exits the air outlet portion into the interior space of the housing structure such that the interior space of the housing structure is pressurized thereby causing the air to flow though the gap provided between the key opening and the at least one key.
