Standard Directional Gyroscopes
4000B-series
-
The 4000B is our standard air-driven directional gyro. As the aircraft turns left or right, gears on the sensing unit and dial shaft translate this rotation into rotation of the instrument’s vertical dial. Left turns produce clockwise dial rotation and right turns produce counter-clockwise rotation. The gyro is controlled by a heading selector knob located on the lower left of the instrument. Pressing and turning the knob first disengages the dial shaft and then resets the dial to a new heading, which results in a new course indication. Releasing the selector knob re-engages the dial shaft. The on-course position of the pointer is always at the top of the azimuth circle (0° on the dial with the aircraft headed north).

Serializer/Deserializers & Selector Muxes
-
Serializer/Deserializer muxes use both rising and falling edges of the clock to serialize the data from parallel inputs to serial output while demuxes deserialize the data from its serial input to parallel outputs. Selector muxes routes the differential inputs to either one or more of the desired outputs upon assertion of the appropriately selected port. Muxes can be used in various applications including High Data Rate Ethernet, Fiber Communication, Signal Routing and Broadband Test & Measurement Equipment.

The Emergency Interseat Sequencing System (EISS) was designed an qualified for the F-15K Fighter and has since been installed in the F-15SG and F-15SA configurations of the F-15. The system consists of Thermal Batteries with Initiators, a Digital Interseat Sequencer, Mode Selector, and customer provided cabling Electro-Explosive Devices (EEDs). The system is operated from either thermal battery and aircraft 28Vdc for redundancy. A separate field Test Set (EESSTS) performs both complete system continuity tests and an operational test of the total system installed in the aircraft. The sequencer is programmable and could be used in any escape system.Based on the initiation point, Forward or Aft Seat Handle, Internal or External Canopy Jettison Handles, and the Mode Selector setting, the Sequencer provides firing pulses to the EEDs to support canopy removal, ejection seat inertial reel activation(s) and ejection seat catapult firing(s). Sensing capabilities are provided to determine system state, canopy gone, seat gone, so as to provide the optimum escape timing.
