Abstract: A switching operation is performed in response to an externally applied DC control signal from an external load. An input connector receives an input audio signal from an external audio source, and an output connector that provides an audio output signal. A DC isolator couples the input audio signal from the input connector as the audio output signal on the output connector while isolating the externally applied DC control signal from the input connector. A switch is responsive to the externally applied DC control signal applied to the output connector so as to perform the switch operation.

Abstract: A coaxial jack has an electrically groundable housing including first and second ports, a printed circuit board supporting a terminating element and conductive traces, and a center conductor disposed within the electrically groundable housing. The center conductor extends through a hole in the printed circuit board and is normally coupled to the electrically groundable housing contact through the terminating element and the conductive traces. A grounding spring has a leaf spring that acts as switch to break the coupling when a plug is inserted into the first port.

Abstract: A switching coaxial jack has an electrically grounded housing that supports first and second connectors at a first end of the housing and third and fourth connectors at a second end of the housing. A first center conductor is disposed within the first connector, a second center conductor is disposed within the second connector, a third center conductor is disposed within the third connector, and a fourth center conductor is disposed within the fourth connector. A sliding switch within the housing has a first position that electrically couples the first and third center conductors to one another and a second position that electrically couples the first center conductor to one of the second center conductor and the terminating element.

Abstract: Accelerations due to excitation of the natural modes of an aircraft's body are suppressed by an active suppression system. Dedicated accelerometers are positioned in the aircraft at optimal locations for sensing modal induced lateral accelerations. The accelerometer produced signals are processed through control logic which, in response thereto, and in response to aircraft velocity and altitude related signals produces output control signals. The control signals effect rudder deployment creating forces to suppress the natural mode induced accelerations.

Abstract: An improved push-push switch (10) suitable for complete automatic assembly is disclosed. The push-push switch (10) contains essentially two moving parts comprising an actuator (50) and a cam (60), the cam (60) coupled by keyway connections (63) for rotation with the actuator (50). Switch contacts (43, 47, 49) are located adjacent the moving switch parts in order to effect a make and break type of switch operation. The actuator (50) has interior (56) and exterior (54) gear teeth which mesh with cover gear teeth (36) and housing gear teeth (14), respectively, to effect rotation of the actuator (50) and the cam (60). The configuration of the cover gear teeth (36) and the associated interior actuator gear teeth (56) provide an axial over-travel of the actuator (50) without effecting any appreciable rotational movement of the actuator (50), thereby compensating for accumulated manufacturing tolerances without affecting switching functions relative to axial displacement of the actuator (50).

Abstract: A multi-stage pressure switch (10) transduces partial vacuum pressure levels to corresponding electrical outputs. The switch (10) comprises a vacuum housing (12) having a bore (16) therein and a port (14) at one end. Positioned within the bore (16) and in engagement with one end of a coaxial spring (48), is a rubber piston (50) having an integral lip seal (54) which wipably engages the wall of the bore, the piston (50) also having a socket (56) disposed therein. A U-shaped switch drive arm (38) has a drive arm extension (40) and ball (41) received within the socket (56) of the rubber piston (50). Contactors (42, 43, and 44,45) are mounted on opposite sides of the drive arm (38). A switch housing (28) having two sets of terminals (32, 33, and 34,35) extending into the housing and terminating at different levels is joined with the vacuum housing (12).
