Abstract: A communication console may include a moveable plunger including a body and an arm. The arm may connect to and extend away from the body. A first element may be coupled to the arm. The first element may include a top point and a bottom point, the axis of displacement extending between the top point and the bottom point. The first element may move with the arm along the axis of displacement. A second element may be detached from the arm and positioned adjacent to the axis of displacement. Additionally, one of the first element or the second element may be a sensing element and another may be a detectable element. The sensing element may sense a spatial position of the detectable element and output an indication of a position of the plunger based on the spatial position of the detectable element.

Abstract: An electronic device may include a housing and a directional microphone. The housing may include a front surface, a rear surface positioned opposite the front surface, and a hollow cavity positioned between the front surface and the rear surface. The hollow cavity may include a front opening defined in the front surface and a rear opening defined in the rear surface. The directional microphone may include a front port and a rear port. The directional microphone may be mounted in the hollow cavity of the housing with the front port oriented toward the front opening and with the rear port oriented toward the rear opening.

Abstract: A test apparatus and method of electrical testing especially useful for verifying normal performance of essential functions in an aircraft atmospheric pressure responsive auxiliary altimeter under either of flight line or maintenance shop conditions. The tester provides electrical power and control signals needed to energize each of three functions in the considered altimeter instrument including instrument face illumination, altimeter stiction-limiting mechanical vibration generation, aircraft output signal generating potentiometer function and enables electrical current and voltage monitoring relating to the instrument functions being tested. Replacement of individual test instruments and other informal test apparatus with a convenient and probably more electrical accident-free integrated tester is contemplated.
